Description

  The present invention relates to a room temperature thermal equilibrium system that can contribute to uniform room temperature in a dwelling unit and can suppress health damage such as heat shock in residential facilities such as houses, accommodation facilities, and hospitals.

  In recent years, power saving at home has been demanded throughout the year due to the situation where it is difficult to restart the nuclear power plant. On the other hand, the residence time has become longer due to aging, and the improvement of the thermal comfort of the living space is attracting attention again. However, in order to save electricity, the room temperature setting for air conditioners, etc. is set higher in summer and lower in winter. It is difficult to change. Here, as a measure for improving the thermal experience without changing the set temperature of an air conditioner or the like, radiant cooling / heating has been conventionally performed. As a typical example, floor heating is widely used (see, for example, Non-Patent Document 1).

  FIG. 8 shows an image of radiant cooling and heating. In the example shown in the figure, a ceiling radiating panel is provided on the ceiling, and a floor heating is provided on the floor, and a refrigerant pipe for circulating a refrigerant is provided for both the ceiling radiating panel and the floor heating. With such a configuration, in the summer, as shown in the image of FIG. 5A, the temperature of the body can be lowered by cooling the ceiling with the ceiling radiating panel. In winter, as shown in the image of FIG. 5B, the temperature of the body can be raised by warming the floor surface by floor heating.

However, in a dwelling unit, the room temperature distribution becomes obvious in summer and winter (for example, hot air pools, cold drafts by the windows, etc.), and thermal comfort cannot be obtained even if the air conditioning equipment is operated at a predetermined set temperature. There are many cases. Further, since the radiant cooling and heating such as the floor heating illustrated above consumes fuel such as gas, this type of radiant cooling and heating technology is not energy saving as a whole system.
Here, for example, in Patent Document 1, an air passage that circulates through each living room is provided in the dwelling unit, and a ventilation means, a temperature detection means, a heat source for cooling or heating, and a control means are provided. A technique for cooling and heating each of the two to a set temperature is disclosed. However, the technique described in Patent Document 1 is similar to the radiant cooling and heating technique in that fuel is consumed in a heat source that is cooled or heated, and is still insufficient for energy saving.

  Therefore, the present invention has been made paying attention to such problems, and in a residential facility such as a house, an accommodation facility, or a hospital, a room temperature thermal equilibrium system capable of achieving both energy saving and improvement of thermal comfort is provided. The purpose is to provide.

In order to solve the above problems, a room temperature thermal equilibrium system according to one aspect of the present invention is a room temperature thermal equilibrium system that converges the room temperature of a plurality of rooms into a thermal equilibrium state, and is a ceiling finish surface of each room. The end of the metal plate and the metal plate of the adjacent rooms straddle each other in a state where the end protrudes from the ceiling space of each of the plurality of rooms, and the end of the metal plate contacts each other in the ceiling space. and wherein the obtaining Bei and the installed heat transfer member Te.

According to the room temperature thermal equilibrium system according to one aspect of the present invention, the metal plates are used as the ceiling finish surfaces of the rooms, and the heat transfer members are adjacent to each other in the state where the ends of the heat transfer members protrude from the ceiling space of the plurality of rooms. since its ends in the ceiling space are placed in contact respectively with the metal plates of adjacent rooms mutually straddling, a metal plate and the heat transfer member as a heat transfer medium, naturally a plurality of chambers It can be converged to a thermal equilibrium state. Thereby, it can contribute to equalization of room temperature in a dwelling unit and can control health hazards, such as a heat shock. Therefore, thermal comfort can be improved. And according to the room temperature thermal equilibrium system which concerns on 1 aspect of this invention, since a metal plate and a metal heat-transfer member are used as a heat transfer medium, it saves energy without consuming electricity, gas, etc.

Here, in the room-temperature thermal equilibrium system according to an embodiment of the present invention, when or the base of the ceiling finished surface (a metal plate) in light-gauge steel, it is more preferable for further improving the response of the heat transfer between rooms .

In the room temperature thermal equilibrium system according to one aspect of the present invention, if the metal plate and the heat transfer member are made of aluminum or stainless steel having a higher thermal conductivity than the gypsum board, the metal plate and the heat transfer member are placed in a room. It is suitable when it is set as the heat transfer medium which improves the response of the heat transfer between.
Furthermore, if the heat transfer member is a heat pipe, it can be expected that the heat transfer speed is further increased. Here, the “heat pipe” refers to a heat transfer member in which a small amount of a heat transfer medium working fluid is vacuum-sealed in a closed hollow rod-like body and a capillary structure is provided on the inner wall. When the end of the heat pipe is heated, (1) the working fluid evaporates in the heating section (absorption of latent heat of evaporation), (2) the steam moves to the low temperature section, and (3) the steam condenses in the low temperature section (latent evaporation heat). And (4) a heat transfer cycle in which the condensed hydraulic fluid returns to the heating section by capillary action.

  As described above, according to the present invention, it is possible to achieve both energy saving and improvement of thermal comfort in residential facilities such as houses, accommodation facilities, and hospitals.

Hereinafter, an embodiment of a room temperature thermal equilibrium system of the present invention will be described with reference to the drawings as appropriate.
As shown in FIG. 1A, in this room temperature thermal equilibrium system, as a plurality of rooms, a metal plate 1 is used as a ceiling finish surface for each of the living rooms A and B with respect to the adjacent living rooms A and B. In addition, when making the metal plate 1 into a ceiling finishing surface, a design, such as a pattern, can be given to the metal plate surface, and an external appearance can be improved. A design such as a pattern can be applied by providing irregularities on the surface of the metal plate or printing.

  Moreover, with respect to the adjacent living rooms A and B, the solid bar-shaped heat transfer member 2 is installed across the living rooms in a state where the end portion 2t protrudes from the ceiling space T of the adjacent living rooms A and B. Has been. Furthermore, the part M straddling between the living rooms A and B where the heat transfer member 2 is adjacent becomes a heat transfer path between the adjacent living rooms A and B with the heat transfer member periphery of the straddling part M covered with the heat insulating material 3. ing. Here, the metal plate 1 and the rod-shaped heat transfer member 2 are each made of a metal (for example, aluminum or stainless steel) having a higher thermal conductivity than the gypsum board. In addition, if a heat pipe is used for the rod-shaped heat transfer member 2, it can be expected that the heat transfer performance is further improved.

According to this room temperature thermal equilibrium system, in the adjacent rooms A and B, the heat of the air in each room is transmitted to the heat transfer member 2 via the metal plate (ceiling finish surface) 1 and the air in the ceiling space T, Furthermore, it moves to the adjacent rooms A and B through the heat transfer member 2. Therefore, finally, the two rooms A and B converge to the same air temperature and are in a thermal equilibrium state. In addition, although the example of Fig.1 (a) is a comparative example with which the metal plate 1 and the heat-transfer member 2 were spaced apart by the ceiling back space T with respect to this invention , the response of heat transfer is further improved. In doing so, it is preferable to place the metal plate 1 and the heat transfer member 2 in contact with each other in the ceiling space T as in the embodiment of the present invention shown in FIG. Further, in order to further improve the heat transfer response, it is preferable that the base of the metal plate (ceiling finish surface) 1 is a lightweight steel frame.

  Here, the thermal conductivity is about 250 W / (m · K) for aluminum, about 25 W / (m · K) for stainless steel, and about 0.2 W / (m · K) for gypsum board. Therefore, for example, when the room temperature thermal equilibrium system of the present invention is applied to room A at room temperature 30 ° C. and room B at room temperature 10 ° C., aluminum is about 1250 times faster than gypsum board and about 125 for stainless steel. Heat can be transferred at twice the speed, and finally both living rooms A and B can naturally converge to a room temperature of 20 ° C.

  As described above, according to the room temperature thermal equilibrium system of the present invention, the adjacent rooms A and B are connected to each other using a material having a high thermal conductivity as a heat transfer medium, so that it can be quickly performed without consuming electricity or gas. Energy is saved because heat is transferred. Moreover, since it can contribute to equalization of the room temperature in a dwelling unit, health hazards, such as a heat shock, can be suppressed and thermal comfort can be improved.

It should be noted that the room temperature thermal equilibrium system according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.
For example, in the above-described embodiment, the adjacent rooms A and B have been described as a plurality of rooms as an example. However, the present invention is not limited to this. For example, as illustrated in FIG. 2, the dwelling unit includes a living room C and two adjacent rooms. Even when the rooms A and B are provided, the room temperature thermal equilibrium system can be applied to these three rooms.

  Thus, on hot summer days (Fig. (A)) and warm winter days (Fig. (B)), the room (western rooms) A, B separated from the living room C by the room temperature thermal equilibrium system of the present invention. Since the heat transfer to each other and the heat transfer between the adjacent living rooms A and B can be promoted, the room temperature of the entire dwelling unit can be made uniform. The arrows shown in FIG. 6A indicate that the room temperature heat balance system of the present invention moves the living room C from the living room C, which has become hot in the strong sunlight in the summer, to the living rooms (Western rooms) A and B, which are cool and sunny. The image of lowering the room temperature of C is shown. Moreover, the arrow shown to the figure (b) is the cold room (Western style room) by the heat which moves from the living room C which became warm by the sunlight of winter to the cold room (Western style room) A and B by the room temperature thermal equilibrium system of this invention. The image which raises the room temperature of A and B is shown.

In addition, the effect of cooling in the living room C is transmitted to the rooms A and B by the room temperature thermal equilibrium system of the present invention in summer, and the effect of heating in the living room C is transmitted in the winter room by the room temperature thermal equilibrium system of the present invention. It can also be communicated to rooms A and B. This method makes it possible to reduce the number of air conditioning units.
Further, for example, in the above-described embodiment, as an example of a metal heat transfer member installed across the rooms in a state where the end portion of each room protrudes from the ceiling space of a plurality of rooms, Although the heat member 2 has been described as an example, the shape of the heat transfer member is not limited thereto, and may be, for example, a belt shape, a net shape, or a plate shape, or may be a hollow tube shape. An example of a hollow tubular heat transfer member is a heat pipe.

  For example, in the above embodiment, the living rooms A and B have been described as a plurality of rooms. However, the present invention is not limited to this, and the room to which the present invention is applicable is a concept including a bath, a dressing room, and a toilet. . Further, for example, in the above-described embodiment, an example in which a plurality of rooms are separated from each other with a corridor or the like is described. However, the present invention is not limited to this, and heat transfer is performed if the plurality of rooms are adjacent to each other. Since there is no part where the members straddle between the rooms, the metal plate that is the ceiling finish surface of each room and the end of the ceiling projecting in each room are overhanging each other. By providing the heat transfer member, a room temperature thermal equilibrium system according to one embodiment of the present invention can be configured.

  Specifically, FIG. 3 shows an example applied to an adjacent bath and dressing room. As shown in the figure, when the room temperature thermal equilibrium system of the present invention is applied to a bath and a dressing room, the heat of the bath moves to the dressing room, and the room temperature of the dressing room can be raised and the cold can be relieved. Note that the metal plate 1 constituting the room temperature thermal equilibrium system of the present invention is provided so as to cover the entire ceiling of the room as in the above embodiment, and as shown in FIG. You can also Moreover, as shown in FIG. 4, if the room temperature heat balance system of this invention is applied to a living room and a toilet, the warm temperature of a living room moves to a toilet, the room temperature of a toilet can be raised, and cold can be relieved.

For example, in the said embodiment, although the heat-transfer member 2 which comprises the room temperature thermal equilibrium system of this invention demonstrated in the example made into the solid rod-shaped integral structure, it is not restricted to this, Heat-transfer member 2 is made into several members. The plurality of members can be connected to each other and extended, or the connection and interruption of heat transfer between the members can be switched.
Specifically, the modification shown in FIGS. 5 and 6 is configured to be able to switch between connection and disconnection of heat transfer of the heat transfer member 2. In this example, as shown in FIG. 5, in the hallway part located on the opposite side to the rooms A and B, the heat transfer member 2 is transferred to the end position (reference numeral Z) of the heat insulating material 3 near the wall surface. A switching mechanism is provided that enables switching between connection and disconnection of heat.

  Specifically, as shown in FIG. 6, this switching mechanism divides the heat transfer member 2 into a plurality of members 2 a and 2 b, and the adjacent members 2 a and 2 b are spaced apart from each other. ing. A connecting metal plate 2c that is in contact with the ends of the adjacent members 2a and 2b is provided so as to be able to contact and separate from the upper portions of the members 2a and 2b. A vertical bar 4 is fixed vertically downward to the connecting metal plate 2c, and the lower part of the vertical bar 4 is in contact with a push button switch 5 provided on the wall surface. The push button switch 5 can be moved back and forth in the left-right direction in the figure by a pressure operation along a horizontal plane. The back side of the push button switch 5 is a contact surface 5a with the connecting metal plate 2c, and the contact surface 5a has a sloped slope so that it functions as a cam surface. When the operation is not performed, as shown in FIG. 5A, the push button switch 5 is retracted in the left direction of the drawing, so that the vertical bar 4 is in contact with and held on the contact surface 5a at the position moved downward. At this time, the connecting metal plate 2c allows the heat transfer member 2 to transfer heat with the members 2a and 2b in a heat transfer communication state. On the other hand, when the push button switch 5 is pressed, the push button switch 5 moves to the right as shown in FIG. The bar 4 slides up the slope obliquely, and the uppermost connecting metal plate 2c of the vertical bar 4 is separated from the ends of the adjacent members 2a and 2b. Thereby, as a result of the metal plate 2c for connection separating from the heat-transfer member 2, heat transfer is interrupted | blocked. With such a configuration, it is possible to appropriately switch effectiveness / ineffectiveness of heat transfer by the room temperature thermal equilibrium system of the present invention.

  Next, FIG. 7 shows an example in which the heat transfer member 2 is composed of a plurality of members, and the plurality of members are connected and extended. As shown in FIG. 2A, in this example, the heat transfer member 2 has a divided structure at two positions (reference numeral Y) where the heat transfer member 2 is covered with the heat insulating material 3. As shown in FIG. 2B, each divided portion has a divided structure composed of a plurality of members 2a, 2b, 2c. This divided structure divides the rod-shaped heat transfer member 2 into a plurality of members 2a, 2b. Thus, the end portions of the adjacent members 2a and 2b are provided apart from each other. A connecting metal plate 2c that is in contact with the ends of the adjacent members 2a and 2b is fixed to the ends of the members 2a and 2b from above. The fixing method using the connecting metal plate 2c is not easily peeled off by soldering or the like. With such a configuration, even if the separation distance between the plurality of rooms to which the room temperature thermal equilibrium system of the present invention is applied is long, the plurality of rooms are brought into a heat transfer communication state by the heat transfer member 2. This is preferable.
