Description

This disclosure relates to a refrigerant recovery cylinder cooling device that cools a refrigerant recovery cylinder.

Conventionally, a cooling device for a refrigerant recovery cylinder is known that includes a cooling member that is in surface contact with the side surface of the refrigerant recovery cylinder, and a water supply member that supplies water to the cooling member. When the cooling member is in surface contact with the side surface of the refrigerant recovery cylinder, water is supplied from the water supply member to the cooling member, causing the water supplied to the cooling member to evaporate. The refrigerant recovery cylinder is cooled by the water supplied to the cooling member evaporating (see, for example, Patent Document 1).

However, the cooling member is cylindrical in shape to match the shape of the side of the refrigerant recovery cylinder. Because the cooling member is cylindrical in shape to match the shape of the side of the refrigerant recovery cylinder and is in surface contact with the side of the refrigerant recovery cylinder, it is time-consuming to attach and detach the cooling member to the side of the refrigerant recovery cylinder. As a result, there was a problem in that it was time-consuming to cool the refrigerant recovery cylinder.

Embodiment 1.
1 is a perspective view showing a refrigerant recovery cylinder to which a cooling device for a refrigerant recovery cylinder according to embodiment 1 is attached. The cooling device 1 for a refrigerant recovery cylinder according to embodiment 1 is a device for cooling a refrigerant recovery cylinder 2.

The refrigerant recovery cylinder 2 is a container for recovering the refrigerant flowing through the refrigerant circuit included in the air conditioner or refrigeration device. The refrigerant recovery cylinder 2 is connected to the refrigerant circuit via piping 201 for refrigerant recovery. Refrigerant recovered from the refrigerant circuit is placed into the refrigerant recovery cylinder 2 via piping 201. The refrigerant placed in the refrigerant recovery cylinder 2 is in the form of a high-pressure gas. The maximum weight of refrigerant that can be placed in the refrigerant recovery cylinder 2 is, for example, 10 kg or 20 kg.

The refrigerant recovered in the refrigerant recovery cylinder 2 is, for example, R410.

When the temperature around the refrigerant recovery cylinder 2 is high, the pressure of the refrigerant stored in the refrigerant recovery cylinder 2 increases. When the pressure of the refrigerant stored in the refrigerant recovery cylinder 2 is high, it becomes difficult for the refrigerant to enter the refrigerant recovery cylinder 2. As a result, when the temperature around the refrigerant recovery cylinder 2 is high, the recovery efficiency of the refrigerant in the refrigerant recovery cylinder 2 decreases. Therefore, when the temperature around the refrigerant recovery cylinder 2 is high, it is necessary to cool the refrigerant recovery cylinder 2.

The shape of the refrigerant recovery cylinder 2 is cylindrical. Therefore, the shape of the side surface 202 of the refrigerant recovery cylinder 2 is circular when viewed from above. The refrigerant recovery cylinder 2 is made of iron. Therefore, the refrigerant recovery cylinder 2 is magnetized by a magnet.

The cooling device 1 for the refrigerant recovery cylinder in embodiment 1 includes a long member 101, a cooling liquid supply member 102, and a cooling liquid recovery member 103.

The long member 101 has a flow path 105 through which the cooling liquid 104 flows. The flow path 105 is formed to extend in the longitudinal direction of the long member 101. The long member 101 is capable of being curved. Therefore, the long member 101 can be wound around the side surface 202 of the refrigerant recovery cylinder 2. The longitudinal dimension of the long member 101 is several times larger than the outer circumferential dimension of the side surface 202 of the refrigerant recovery cylinder 2. Therefore, the long member 101 can be wound in a spiral shape around the side surface 202 of the refrigerant recovery cylinder 2.

An opening 106 connected to the flow path 105 is formed on the side of the long member 101. The opening 106 is formed to extend in the longitudinal direction of the long member 101. When the long member 101 is attached to the side 202 of the refrigerant recovery cylinder 2, the long member 101 is positioned so that the opening 106 faces upward.

The elongated member 101 is made of, for example, iron, copper, or aluminum. Note that the material that makes up the elongated member 101 is not limited to iron, copper, or aluminum, and may be any material that has high thermal conductivity.

The cooling liquid 104 is composed of, for example, water. Note that the material that composes the cooling liquid 104 is not limited to water, and may be any liquid that can cool the refrigerant recovery cylinder 2 by flowing through the flow path 105.

The cooling liquid supply member 102 has a cylindrical shape. The cooling liquid supply member 102 has a shape that allows it to be carried by an operator. The cooling liquid supply member 102 is, for example, made of a plastic bottle. The cooling liquid supply member 102 is filled with cooling liquid 104 in advance. This makes it possible to secure the amount of cooling liquid 104 required for the refrigerant recovery work in advance, even if the refrigerant recovery work is performed in a place without a water faucet, such as the rooftop of a building.

The coolant supply member 102 is held by an operator. When the operator holds the coolant supply member 102 and tilts the coolant supply member 102 relative to a vertical line, the coolant 104 flows from the inside to the outside of the coolant supply member 102. The coolant 104 that flows from the inside to the outside of the coolant supply member 102 enters the flow path 105 of the long member 101.

The cooling liquid recovery member 103 is composed of a container that stores the cooling liquid 104. The cooling liquid recovery member 103 stores the cooling liquid 104 that has passed through the flow path 105. This makes it possible to recover the cooling liquid 104 used in the refrigerant recovery operation and transport the recovered cooling liquid 104 to the drainage facility, even if the refrigerant recovery operation is performed in a location without a drainage facility, such as the rooftop of a building.

Figure 2 is a cross-sectional view showing the main parts of the refrigerant recovery cylinder 2 to which the cooling device 1 for the refrigerant recovery cylinder of Figure 1 is attached. The cooling device 1 for the refrigerant recovery cylinder further includes an attachment member 107. The attachment member 107 is provided on the long member 101. The attachment member 107 is also attached to the side of the long member 101. The attachment member 107 can be fixed to the long member 101, for example, by using an adhesive.

The mounting member 107 is composed of a permanent magnet. Therefore, the mounting member 107 is removably attached to the side surface 202 of the refrigerant recovery cylinder 2 using magnetic force. The mounting member 107 has a sheet shape. The mounting member 107 is capable of being curved and deformed, similar to the long member 101. Therefore, the mounting member 107 can be wound in a spiral shape around the side surface 202 of the refrigerant recovery cylinder 2 together with the long member 101.

Next, the procedure for cooling the refrigerant recovery cylinder 2 using the cooling device 1 for the refrigerant recovery cylinder will be described. First, the worker winds the long member 101 in a spiral shape around the side surface 202 of the refrigerant recovery cylinder 2, and attaches the long member 101 to the side surface 202 of the refrigerant recovery cylinder 2 via the attachment member 107 while the long member 101 is wound in a spiral shape around the side surface 202 of the refrigerant recovery cylinder 2. When the long member 101 is wound in a spiral shape around the side surface 202 of the refrigerant recovery cylinder 2, the worker adjusts the position of the long member 101 so that the long member 101 is wound over the entire height of the side surface 202 of the refrigerant recovery cylinder 2.

When winding the long member 101 in a spiral shape around the side 202 of the refrigerant recovery cylinder 2, the worker places one longitudinal end of the long member 101 on the upper part of the side 202 of the refrigerant recovery cylinder 2, and places the other longitudinal end of the long member 101 on the lower part of the side 202 of the refrigerant recovery cylinder 2. In addition, when winding the long member 101 in a spiral shape around the side 202 of the refrigerant recovery cylinder 2, the worker places the long member 101 so that the height direction is downward from one longitudinal end of the long member 101 to the other longitudinal end of the long member 101.

Then, the worker places the coolant recovery member 103 below the portion of the flow path 105 located at the other longitudinal end of the long member 101. When placing the coolant recovery member 103, the worker adjusts the position of the coolant recovery member 103 so that the coolant 104 that has passed through the flow path 105 of the long member 101 enters the coolant recovery member 103.

Then, the worker uses the cooling liquid supply member 102 to pour the cooling liquid 104 into the flow path 105 located at one end of the long member 101 in the longitudinal direction. The cooling liquid 104 poured into the flow path 105 flows through the flow path 105. The cooling liquid 104 that has passed through the flow path 105 enters the cooling liquid recovery member 103.

The cooling liquid 104 flows through the flow path 105, thereby cooling the entire long member 101. As the long member 101 is cooled, the side surface 202 of the refrigerant recovery cylinder 2 is cooled via the mounting member 107.

The long member 101 is wound over the entire height of the side surface 202 of the refrigerant recovery cylinder 2. Therefore, the entire height of the side surface 202 of the refrigerant recovery cylinder 2 is cooled.

The refrigerant contained in the refrigerant recovery cylinder 2 is cooled by cooling the side surface 202 of the refrigerant recovery cylinder 2. The pressure of the refrigerant contained in the refrigerant recovery cylinder 2 is reduced by cooling the refrigerant contained in the refrigerant recovery cylinder 2. As a result, a sufficient amount of refrigerant recovered from the refrigerant circuit enters the refrigerant recovery cylinder 2. When a sufficient amount of refrigerant recovered from the refrigerant circuit enters the refrigerant recovery cylinder 2, cooling of the refrigerant recovery cylinder 2 using the refrigerant recovery cylinder cooling device 1 is completed.

As described above, the cooling device 1 for the refrigerant recovery cylinder according to the first embodiment includes a long member 101 that is formed with a flow path 105 through which the cooling liquid 104 flows and is capable of being bent and deformed, and an attachment member 107 provided on the long member 101. The attachment member 107 is detachably attached to the side surface 202 of the refrigerant recovery cylinder 2 using magnetic force. The flow path 105 is formed extending in the longitudinal direction of the long member 101. The long member 101 is attached to the refrigerant recovery cylinder 2 via the attachment member 107 in a state where it is spirally wound around the side surface 202 of the refrigerant recovery cylinder 2. With this configuration, the long member 101 can be easily attached to and detached from the side surface 202 of the refrigerant recovery cylinder 2. As a result, the work efficiency of cooling the refrigerant recovery cylinder 2 can be improved.

The long member 101 can also be curved. This allows the shape of the long member 101 to be changed to match the shape of the side surface 202 of the refrigerant recovery cylinder 2. Therefore, the long member 101 can be wound in a spiral shape around each of the side surfaces 202 of multiple types of refrigerant recovery cylinders 2, each of which has a different shape of the side surface 202. As a result, the refrigerant recovery cylinder cooling device 1 can be used for multiple types of refrigerant recovery cylinders 2.

In addition, an opening 106 connected to the flow path 105 is formed on the side of the long member 101. The opening 106 is formed to extend in the longitudinal direction of the long member 101. With this configuration, the cooling liquid 104 can be easily introduced into the flow path 105 from the opening 106. As a result, the operation of introducing the cooling liquid 104 into the flow path 105 can be easily performed.

The long member 101 is arranged so that the opening 106 faces upward when the long member 101 is wound in a spiral shape around the side surface 202 of the refrigerant recovery cylinder 2. With this configuration, the cooling liquid 104 can be easily introduced into the flow path 105 from the opening 106. As a result, the operation of introducing the cooling liquid 104 into the flow path 105 can be easily performed.

Embodiment 2.
3 is a perspective view showing a refrigerant recovery cylinder to which a cooling device for a refrigerant recovery cylinder according to embodiment 2 is attached. The cooling device 1 for a refrigerant recovery cylinder according to embodiment 2 further includes a housing 108 and a fan 109. In FIG. 3, a part of the housing 108 is shown cut away so that the inside of the housing 108 can be seen.

The housing 108 has a cylindrical portion formed into a cylindrical shape. The refrigerant recovery cylinder 2 is accommodated inside the housing 108 with the long member 101 spirally wound around the side surface 202 of the refrigerant recovery cylinder 2. Therefore, the refrigerant recovery cylinder 2, the long member 101, and the mounting member 107 are accommodated inside the housing 108.

The housing 108 has a top plate provided on the upper part of the cylindrical portion of the housing 108. The top plate of the housing 108 has one through hole 110 formed therein. The through hole 110 passes through the top plate of the housing 108 in the axial direction of the cylindrical portion of the housing 108.

A plurality of through holes 111 are formed in the lower part of the cylindrical portion of the housing 108. Each through hole 111 penetrates the cylindrical portion of the housing 108 in the radial direction of the cylindrical portion of the housing 108. The plurality of through holes 111 are arranged in a line in the circumferential direction of the cylindrical portion of the housing 108.

Air can pass through each of the through holes 110 and 111.

A single opening 112 is formed in the lower part of the cylindrical part of the housing 108. In other words, the lower part of the cylindrical part of the housing 108 is open. The refrigerant recovery cylinder 2, to which the long member 101 is attached via the mounting member 107, passes through the opening 112 from below, and the refrigerant recovery cylinder 2, the long member 101, and the mounting member 107 are housed inside the housing 108.

When viewed from above, the housing 108 is positioned inside the side wall of the coolant recovery member 103.

The fan 109 is disposed in the through-hole 110. When the fan 109 is driven, the air inside the housing 108 is forced out to the outside of the housing 108. Specifically, when the fan 109 is driven, air enters the housing 108 from the outside through the multiple through-holes 111 into the housing 108, and air exits the housing 108 from the inside through the through-hole 110. Thus, the fan 109 generates a flow of air that passes through the housing 108.

The fan 109 is driven by a dry cell (not shown) as a power source. This allows the fan 109 to be driven even when the refrigerant recovery work is performed in a place where there is no power source such as an electrical outlet. The fan 109 may also be driven by a power source such as an electrical outlet.

The generation of an air flow passing through the housing 108 causes air to flow around the long member 101 wound in a spiral shape on the side surface 202 of the refrigerant recovery cylinder 2. The air flowing around the long member 101 wound in a spiral shape on the side surface 202 of the refrigerant recovery cylinder 2 promotes evaporation of the cooling liquid 104 flowing through the long member 101. The promotion of evaporation of the cooling liquid 104 flowing through the long member 101 cools the long member 101. The cooling of the long member 101 cools the refrigerant recovery cylinder 2 via the mounting member 107.

In addition, the long member 101, which is wound in a spiral shape around the side surface 202 of the refrigerant recovery cylinder 2, is cooled by air flowing around the long member 101. The cooling of the long member 101 cools the refrigerant recovery cylinder 2 via the mounting member 107.

Air that passes through the through-hole 111 from the outside of the housing 108 to the inside of the housing 108 passes close to the cooling liquid 104 stored in the cooling liquid recovery member 103. By passing close to the cooling liquid 104, the air that passes through the through-hole 111 from the outside of the housing 108 to the inside of the housing 108 is cooled.

Figure 4 is a perspective view showing the state in which the housing 108 and the fan 109 in Figure 3 have been removed from the refrigerant recovery cylinder 2. The cooling device 1 for the refrigerant recovery cylinder according to the second embodiment further includes a cooling liquid circulation device 113.

The cooling liquid circulation device 113 has piping 114, a pump 115, and a flow rate adjustment member 116.

The piping 114 is provided between one longitudinal end of the elongated member 101 and the coolant recovery member 103. The piping 114 is arranged to pass through the inside of the housing 108. The piping 114 may also be arranged to pass through the outside of the housing 108.

The pump 115 is provided in the pipe 114. The pump 115 pumps up the cooling liquid 104 stored in the cooling liquid recovery member 103, and supplies the pumped up cooling liquid 104 to the flow path 105.

The flow rate adjustment member 116 is provided on the piping 114. The flow rate adjustment member 116 can be operated by an operator. By operating the flow rate adjustment member 116, the flow rate of the cooling liquid 104 flowing through the piping 114 is adjusted. By adjusting the flow rate of the cooling liquid 104 flowing through the piping 114, the flow rate of the cooling liquid 104 supplied to the flow path 105 is adjusted. By adjusting the flow rate of the cooling liquid 104 supplied to the flow path 105, the flow rate of the cooling liquid 104 flowing through the flow path 105 is adjusted.

Figure 5 is a cross-sectional view showing the long member 101 and the mounting member 107 wrapped around the side surface 202 of the refrigerant recovery cylinder 2 in Figure 3. The long member 101 has a long member body 117 and a fin portion 118 provided on the long member body 117.

A flow path 105 is formed in the long member body 117. An attachment member 107 is provided on one side in the width direction of the long member body 117. Therefore, one side in the width direction of the long member body 117 is attached to the side 202 of the refrigerant recovery cylinder 2 via the attachment member 107.

The fin portion 118 is provided on the other side in the width direction of the elongated member main body 117. A plurality of grooves 119 are formed in the fin portion 118. Each groove 119 is formed to extend in the longitudinal direction of the elongated member 101. Each groove 119 may be formed to extend in the vertical direction when the elongated member 101 is wrapped around the side surface 202 of the refrigerant recovery cylinder 2.

Air passing through the housing 108 passes around the fin portion 118. As the air passing through the housing 108 passes around the fin portion 118, the fin portion 118 is cooled. As the long member 101 has the fin portion 118, the surface area of the long member 101 is increased. Therefore, the long member 101 is more effectively cooled by the air passing through the housing 108. As the long member 101 is more effectively cooled, the side surface 202 of the refrigerant recovery cylinder 2 is more effectively cooled via the mounting member 107. The other configurations are the same as those of the first embodiment.

Next, the procedure for cooling the refrigerant recovery cylinder 2 using the cooling device 1 for the refrigerant recovery cylinder will be described. First, the worker winds the long member 101 in a spiral shape around the side surface 202 of the refrigerant recovery cylinder 2, and attaches the long member 101 to the side surface 202 of the refrigerant recovery cylinder 2 via the attachment member 107 while the long member 101 is wound in a spiral shape around the side surface 202 of the refrigerant recovery cylinder 2. When the long member 101 is wound in a spiral shape around the side surface 202 of the refrigerant recovery cylinder 2, the worker adjusts the position of the long member 101 so that the long member 101 is wound over the entire height of the side surface 202 of the refrigerant recovery cylinder 2.

When winding the long member 101 in a spiral shape around the side 202 of the refrigerant recovery cylinder 2, the worker places one longitudinal end of the long member 101 on the upper part of the side 202 of the refrigerant recovery cylinder 2, and places the other longitudinal end of the long member 101 on the lower part of the side 202 of the refrigerant recovery cylinder 2. In addition, when winding the long member 101 in a spiral shape around the side 202 of the refrigerant recovery cylinder 2, the worker places the long member 101 so that the height direction is downward from one longitudinal end of the long member 101 to the other longitudinal end of the long member 101.

Then, the worker places the coolant recovery member 103 below the portion of the flow path 105 located at the other longitudinal end of the long member 101. When placing the coolant recovery member 103, the worker adjusts the position of the coolant recovery member 103 so that the coolant 104 that has passed through the flow path 105 of the long member 101 enters the coolant recovery member 103.

The worker then attaches the housing 108 to the refrigerant recovery cylinder 2 so that the refrigerant recovery cylinder 2 is positioned inside the housing 108.

Then, the worker uses the cooling liquid supply member 102 to put the cooling liquid 104 into the cooling liquid recovery member 103. The cooling liquid 104 put into the cooling liquid recovery member 103 enters the part of the flow path 105 arranged at one end of the long member 101 in the longitudinal direction by the cooling liquid circulation device 113. The cooling liquid 104 put into the flow path 105 flows through the flow path 105. The cooling liquid 104 that has passed through the flow path 105 enters the cooling liquid recovery member 103. In addition to the cooling liquid 104, for example, ice may be put into the cooling liquid recovery member 103. By putting ice into the cooling liquid recovery member 103, the temperature of the cooling liquid 104 put into the cooling liquid recovery member 103 can be lowered.

The cooling liquid 104 flows through the flow path 105, thereby cooling the entire long member 101. As the long member 101 is cooled, the side surface 202 of the refrigerant recovery cylinder 2 is cooled via the mounting member 107.

The fan 109 generates an air flow that passes through the housing 108. By generating an air flow that passes through the housing 108, the elongated member 101 is cooled more effectively.

The long member 101 is wound over the entire height of the side surface 202 of the refrigerant recovery cylinder 2. Therefore, the entire height of the side surface 202 of the refrigerant recovery cylinder 2 is cooled.

The refrigerant contained in the refrigerant recovery cylinder 2 is cooled by cooling the side surface 202 of the refrigerant recovery cylinder 2. The pressure of the refrigerant contained in the refrigerant recovery cylinder 2 is reduced by cooling the refrigerant contained in the refrigerant recovery cylinder 2. As a result, a sufficient amount of refrigerant recovered from the refrigerant circuit enters the refrigerant recovery cylinder 2. When a sufficient amount of refrigerant recovered from the refrigerant circuit enters the refrigerant recovery cylinder 2, cooling of the refrigerant recovery cylinder 2 using the refrigerant recovery cylinder cooling device 1 is completed.

As described above, the cooling device 1 for the refrigerant recovery cylinder according to the second embodiment further includes the cooling liquid recovery member 103 and the cooling liquid circulation device 113. The cooling liquid 104 that has passed through the flow path 105 is stored in the cooling liquid recovery member 103. The cooling liquid circulation device 113 pumps up the cooling liquid 104 stored in the cooling liquid recovery member 103 and supplies the pumped up cooling liquid 104 to the flow path 105. According to this configuration, the cooling liquid 104 that has passed through the flow path 105 and is stored in the cooling liquid recovery member 103 is reused and supplied to the flow path 105. This allows the refrigerant recovery cylinder 2 to be cooled more effectively using a constant amount of cooling liquid 104.

The cooling device 1 for the refrigerant recovery cylinder according to the second embodiment further includes a housing 108 and a fan 109. The refrigerant recovery cylinder 2 is housed inside the housing 108 with the long member 101 wound in a spiral shape around the side surface 202 of the refrigerant recovery cylinder 2. The fan 109 generates an air flow passing through the housing 108. This configuration can promote the evaporation of the cooling liquid 104 flowing through the flow path 105. This allows the long member 101 to be cooled more effectively. In addition, by generating an air flow passing through the housing 108, the air flows around the long member 101. By having the air flow around the long member 101, the long member 101 can be cooled more effectively.

The long member 101 also has a long member body 117 and a fin portion 118 that is provided on the long member body 117 and has a groove 119 formed therein. Air passing through the housing 108 passes around the fin portion 118. With this configuration, the air passing through the housing 108 passes around the fin portion 118, thereby cooling the fin portion 118. This allows the long member 101 to be cooled more effectively.

Embodiment 3.
6 is a cross-sectional view showing a main part of a refrigerant recovery cylinder to which a cooling device for a refrigerant recovery cylinder according to embodiment 3 is attached. In the cooling device 1 for a refrigerant recovery cylinder according to embodiment 3, the long member 101 has a contact part 120 that contacts the side surface 202 of the refrigerant recovery cylinder 2. The mounting member 107 has a pair of mounting parts 121 that sandwich the contact part 120 in the thickness direction of the long member 101. The thickness direction of the long member 101 is the direction that coincides with the height direction when the long member 101 is attached to the side surface 202 of the refrigerant recovery cylinder 2.

The contact portion 120 is made of a material having a higher thermal conductivity than the mounting portion 121. Therefore, the thermal conductivity of the contact portion 120 is higher than the thermal conductivity of the mounting portion 121.

The cooling device 1 for the refrigerant recovery cylinder according to the third embodiment further includes a vaporization promotion member 122 provided on the housing 108. The vaporization promotion member 122 is provided on the inner wall surface of the housing 108. The vaporization promotion member 122 promotes the vaporization of water droplets contained in the air passing through the housing 108. The vaporization promotion member 122 is made of, for example, diatomaceous earth.

The air passing through the housing 108 is cooled by promoting the evaporation of water droplets contained in the air passing through the housing 108. The air passing through the housing 108 is cooled, thereby cooling the long member 101. The refrigerant recovery cylinder 2 is cooled by cooling the long member 101. The other configurations are the same as those of the first or second embodiment.

As described above, in the cooling device 1 for the refrigerant recovery cylinder according to embodiment 3, the long member 101 has a contact portion 120 that abuts against the side surface 202 of the refrigerant recovery cylinder 2. The mounting member 107 has a pair of mounting portions 121 that sandwich the contact portion 120 in the thickness direction of the long member 101. According to this configuration, the pair of mounting portions 121 attached to the side surface 202 of the refrigerant recovery cylinder 2 sandwich the contact portion 120. This allows the long member 101 to be more stably attached to the side surface 202 of the refrigerant recovery cylinder 2.

The contact portion 120 is made of a material with a higher thermal conductivity than the mounting portion 121. By having the contact portion 120 contact the side surface 202 of the refrigerant recovery cylinder 2, heat transfer between the long member 101 and the refrigerant recovery cylinder 2 can be performed more effectively. As a result, the refrigerant recovery cylinder 2 can be cooled more effectively.

The cooling device 1 for the refrigerant recovery cylinder according to the third embodiment further includes a vaporization promotion member 122 provided on the inner wall surface of the housing 108. This configuration promotes the vaporization of water droplets contained in the air passing through the housing 108. This allows the elongated member 101 to be cooled more effectively. As a result, the refrigerant recovery cylinder 2 can be cooled more effectively.

In each embodiment, water has been used as an example of the cooling liquid 104. However, the cooling liquid 104 is not limited to water, and may be any liquid that can cool the refrigerant recovery cylinder 2 via the long member 101.

In each embodiment, the configuration of the cooling device 1 for the refrigerant recovery cylinder is described, which includes the long member 101 in which the flow path 105 is formed. In addition to this configuration, the cooling device 1 for the refrigerant recovery cylinder may be configured to further include a cooling liquid retention member that is provided in the flow path 105 and absorbs and retains the cooling liquid 104 supplied to the flow path 105. An example of a material that constitutes the cooling liquid retention member is cotton. By the cooling liquid retention member retaining the cooling liquid 104, the speed of the cooling liquid 104 flowing through the flow path 105 can be reduced. This allows the refrigerant recovery cylinder 2 to be cooled more effectively using a constant amount of cooling liquid 104.

In addition, in each embodiment, the configuration of the cooling device 1 for the refrigerant recovery cylinder including the long member 101 in which the flow path 105 is formed has been described. In addition to this configuration, the cooling device 1 for the refrigerant recovery cylinder may be configured to further include a wall provided in the flow path 105 to block a portion of the cooling liquid 104 supplied to the flow path 105. The wall that blocks a portion of the cooling liquid 104 may be disposed at multiple locations along the flow path 105. By providing a wall that blocks a portion of the cooling liquid 104 in the flow path 105, the speed of the cooling liquid 104 flowing through the flow path 105 can be reduced. This allows the refrigerant recovery cylinder 2 to be cooled more effectively using a constant amount of cooling liquid 104.

In addition, in each embodiment, a configuration in which the long member 101 is wound in a spiral shape on the side surface 202 of the refrigerant recovery cylinder 2 has been described. In addition to this configuration, an inclination angle determining member for determining the inclination angle of the spirally wound long member 101 with respect to the horizontal plane may be further provided. An example of the inclination angle determining member is a triangular sheet. The worker attaches the inclination angle determining member to the side surface 202 of the refrigerant recovery cylinder 2 so that the part corresponding to the base of the triangle in the inclination angle determining member is along the horizontal plane. Then, the worker attaches the long member 101 to the side surface of the refrigerant recovery cylinder 2 along the part corresponding to the hypotenuse of the triangle in the inclination angle determining member. The angle between the base and hypotenuse of the triangle in the inclination angle determining member coincides with the angle determined with respect to the horizontal plane of the spirally wound long member 101. As a result, when the long member 101 is attached to the side surface 202 of the refrigerant recovery cylinder 2, the variation in the angle of the spirally wound long member 101 with respect to the horizontal plane is suppressed.

In addition, in each embodiment, a configuration has been described in which an opening 106 is formed on the side of the long member 101. However, a configuration in which an opening 106 is not formed on the side of the long member 101 is also possible. In this case, the shape of the long member 101 is a tube shape.

In addition, in the second and third embodiments, the configuration in which the cooling liquid 104 that has passed through the pipe 114 enters the flow path 105 as is has been described. However, the cooling liquid circulation device 113 may be configured to further have a spray nozzle that is provided at the outlet portion of the cooling liquid 104 in the pipe 114 and sprays the cooling liquid 104 in a mist form. The mist of cooling liquid 104 sprayed from the spray nozzle is sprayed not only onto the flow path 105 but also onto the side surface 202 of the refrigerant recovery cylinder 2. The refrigerant recovery cylinder 2 can be cooled by spraying the mist of cooling liquid 104 onto the side surface 202 of the refrigerant recovery cylinder 2. In addition, the mist of cooling liquid 104 sprayed onto the side surface 202 of the refrigerant recovery cylinder 2 is vaporized, thereby allowing the refrigerant recovery cylinder 2 to be cooled more effectively. In addition, the mist of cooling liquid 104 sprayed from the spray nozzle may be sprayed onto the evaporation promotion member 122. The mist of cooling liquid 104 sprayed from the spray nozzle is sprayed onto the evaporation promotion member 122, which promotes evaporation of the mist of cooling liquid 104 sprayed onto the evaporation promotion member 122. By promoting evaporation of the mist of cooling liquid 104 sprayed onto the evaporation promotion member 122, the air passing through the housing 108 can be cooled.
