Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is installed in the passageway of a building such as a store or factory, and uses an air shutter to reliably block the cold and hot air flowing through the passageway, and to maintain a constant temperature indoors at all times. This invention relates to an air conditioner that also serves as an air curtain and maintains a clean environment.

[Conventional technology]

Normally, air curtains have a blower mechanism with an electric motor and blower installed inside the horizontally elongated fuselage at the top of the passageway, and the blower blows air downward to block air from inside and outside the room.

[Problem to be solved by the invention]

However, as described above, the conventional mechanism blows only the wind downward from the upper part of the passageway and releases it, so the cold or warm air from outside naturally enters the room, and the cold and warm air inside the room leaks to the outside. Not only did this significantly reduce the cooling and heating environment in the room, but it also caused dust to enter the room at the same time as outside air entered the room, which was an extremely serious drawback in terms of health and hygiene.

The present invention is intended to fundamentally solve the various drawbacks of the conventional air shutters as described above, and is aimed at heating the air curtain to an appropriate temperature and blowing air downward from the top, which is well known. The main purpose of this is to reliably prevent air from entering the passageway between indoor and outdoor areas by changing the direction from left to right and laterally, thereby preventing heat energy generated by conventional machines.

[Means for solving the problem] In order to achieve the above-mentioned purpose, the air curtain/air conditioner according to the present invention has mechanisms such as a filter, blower, electric motor, etc. in the blower room on one air supply side of the horizontally elongated body. , and on the other hand, an inner portion of the air conditioner is provided below both sides of the body of the air conditioner, in which necessary mechanisms such as a silencing mechanism are arranged in the air supply chamber on the air supply side, and a heat exchange coil is disposed diagonally inside the body. An air duct with an air outlet and an air intake duct with an air intake on the front facing side of the air outlet are connected in a portal shape to blow cold air or warm air from the heat exchange coil. The heat exchanger is characterized in that the air is sent out from the air outlet through the air duct, and the delivered air is received from the intake port and circulated back to the heat exchange side.

Furthermore, as described in claim 2, an indoor air outlet is provided at a location such as a side surface of the heat exchange chamber, and a damper mechanism is provided in the air outlet passage, and by opening and closing the damper, an air curtain is created by blowing cold and hot air. The system is configured to supply hot and cold air into the room simultaneously or separately.

[Effect]

A horizontal air conditioner will be placed on the ceiling inside the passageway, and ducts on both sides will be installed in a gate-shape on both sides of the passageway.

After that, when the blower in the blower room is operated, the cold air or warm air, which has been heat-exchanged to a predetermined temperature by the heat exchange coil, passes through the blower duct and is sent out from the outlet into the passageway, functioning as an air shutter. At the same time, the supplied air crosses the passage and is received by the intake port on the opposite side, and this air circulates through the intake duct to perform heat exchange again.

In addition, when the above air shutter is in operation, in a configuration in which an indoor air outlet is opened at a location such as the side of the heat exchange chamber, by opening and closing the damper, the air curtain and the cooling/heating air are blown into the room at the same time, or By supplying air differently to each air conditioner, it is possible to freely provide comfortable air conditioning at all times without significantly lowering the indoor temperature.

Furthermore, if high static pressure or other air conditioning is required, this problem can be easily solved by providing a backup blower in the air supply chamber of the air conditioner main body.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.The air conditioner has a body 1 having an overall horizontally elongated shape, with a blower chamber 2 on one side of the air supply side and an air supply chamber 3 on the other side of the air supply side.
A heat exchange chamber 4 is formed in the central part, various mechanisms such as a filter 5, a blower 6, and an electric motor 7 are placed in the blower chamber 2, and necessary device mechanisms such as a noise reduction mechanism 9 are placed in the air supply chamber 3. At the same time, the heat exchange coil 10 is diagonally arranged in the heat exchange chamber 4, and the drain pan 12 is laid down.

The blower duct 11 is a hollow column having a blower passage 13 installed vertically therein, and has a plurality of outlets 14 or outlet grooves formed in the inner column surface portion thereof to communicate with the blower passage 13. The air outlet 1 is provided with an inlet 15 or a suction groove that receives the air in the inner column surface portion on the side opposite to the air duct 11.
Intake ducts 16 opened in four directions are connected to the lower sides of the fuselage 1 at appropriate intervals in a gate-like configuration.

Further, by forming and slanting the air blowing plate 17 in the column of the air duct 11 as shown by the dotted line in the figure, the air from the main body can be blown almost equally over the entire length of the upper and lower sides of the duct.

Furthermore, the present invention provides an air outlet 18 on the indoor side such as the front and rear surfaces of the body 1, and also provides a damper mechanism 19 in the air outlet passage, and by opening and closing the damper mechanism 19, the air curtain is generated by blowing the cold and hot air. At the same time as the air is sent out, hot and cold air at a predetermined temperature is also fed to the indoor side from the air outlet 18.

In addition, a damper mechanism 20 for opening and closing the air supply passage is disposed in the air supply chamber 3 formed on the air supply side of the air conditioner, and the damper mechanism 20 is opened and closed when supplying cold and hot air only to the indoor side. As a result, it is possible to easily distribute the cooled and warmed air at an ideal temperature into the room, especially near the entrance of the passageway, without using any other air conditioner.

Furthermore, in addition to creating an air curtain at the entrance of a passageway, the present invention can be easily installed as a partition wall in locations with different temperature differences in stores and warehouses, and its effects are enormous.

In addition, a preliminary blower 21 is installed in the air chamber 3 of the air conditioner main body.
It is considered that the system is installed in advance and used when high static pressure air conditioning is required.

〔Effect of the invention〕

As described above, the air conditioner combined with an air curtain according to the present invention has an air conditioner in which necessary cooling/heating air conditioning mechanisms such as a blower, a heat exchange coil, a filter, and a silencing mechanism are installed inside, and an air conditioner on both sides of the air conditioner. Since the blower duct and the intake duct are connected downwardly in a gate-like manner at appropriate intervals within the passage, air is sent in the horizontal direction, unlike conventional air sending in the vertical direction. The curtain can be easily formed, and since the air is blown sideways, the air can reliably and easily be circulated to the intake duct on the opposite side, resulting in a beautiful air curtain that is almost equal throughout the left, right, top and bottom passages. It is possible to find.

In particular, the present invention provides that the air curtain has an appropriate temperature because it is cooled or heated to an appropriate temperature by an air conditioner, and this naturally corrects the temperature difference between indoors and outdoors. It completely prevents the intrusion of outdoor cold and warm air and the leakage of indoor air, and furthermore, the cold and warm air is directly received into the intake duct and returned to the heat exchange room, allowing for more effective heat utilization when used again. This invention is ideal as an energy-saving air conditioner and air curtain making machine.

Further, as described in claim 1, an indoor air outlet is provided at a location such as a side surface of the heat exchange chamber, a damper mechanism is provided in the air outlet passage, and a damper mechanism is provided in the air supply chamber so that the passage can be opened and closed. It has various effects such as being able to supply air conditioning and heating at a predetermined temperature only indoors at will, simultaneously or separately by air curtains by blowing cool and hot air into the room. .
