Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and device for temperature balancing in a building, and is particularly characterized in that it utilizes the radiant heat of the sun incident on windows to reduce the imbalance in temperature distribution within a building. The present invention relates to a method and apparatus for temperature balancing in a building.

Recently, buildings have been constructed with solar collectors installed on their rooftops in order to save on heating, cooling, and utility costs.
Experience with these buildings has shown that solar systems for buildings must be designed from fundamentally different perspectives than solar systems for private residences. In other words, in conventional solar buildings, solar heat collectors are installed on the roof like solar systems in private homes, but the temperature of the hot water obtained from this solar heat collector is significantly higher than the temperature expected at the beginning of the design. At best, it is possible to obtain only low-temperature hot water of the order of (outside temperature +10°C).

This fact shows that the solar system was designed without sufficient knowledge of the building's solar radiation conditions, outside temperature, surrounding wind speed, etc.

As described above, the reason why only low-temperature hot water can be obtained from conventional roof-mounted solar collectors is that the influence of wind in high-rise areas of buildings has not been taken into consideration. For this reason, in solar buildings that rely heavily on roof-mounted solar collectors, only a small portion of the water heater can be saved, and it takes many years to amortize the solar system equipment costs.

On the other hand, despite the low efficiency of solar heat collectors, in high-rise buildings, sunlight entering through windows causes an unexpected increase in cooling costs, so further consideration must be given to the use of solar heat in buildings. No.

Generally, the amount of solar heat input through the windows of a building is quite large, and therefore the temperature distribution inside the building becomes significantly more biased during sunny days than when it is cloudy. For example, on sunny days, rooms on the sunny side of a building can become hot enough to require air conditioning even in the winter, whereas rooms on the shaded side of the building can have their heating turned off even in the spring or fall. is impossibly low. In this way, sunlight has the effect of biasing the temperature distribution within a building, so it has rather become an obstacle when the aim is to equalize the temperature distribution within a building. Therefore, in the design of modern office buildings in which ventilation and temperature control inside the building are performed solely by air conditioning equipment, the amount of solar radiation input to windows and exterior walls is calculated as the cooling load. No attempt has been made to actively utilize heat to correct the imbalance in temperature distribution within the building. In addition, in the design of buildings and private residences that are configured to adjust the temperature inside the building by opening windows, the bias in the temperature distribution inside the building caused by the amount of solar heat input can be It had not been considered to correct the problem by using heat itself.

This invention was made against the background as described above,
The purpose of this invention is to eliminate errors in conventional building solar systems, and correct the imbalance in temperature distribution inside a building caused by the amount of solar radiation input from windows by utilizing the solar radiation itself. It is an object of the present invention to provide a method and device for temperature balancing in a building that can minimize temperature differences at various locations.

The method according to the present invention utilizes the radiant heat of sunlight incident on a window on the sunny side of a building to provide movement energy to a heat transport fluid, and transfers the heat transport fluid to a room or a cool area in a shaded part of the building. It is characterized by correcting significant deviations in temperature within the building by allowing natural flow. Furthermore, the in-building temperature balance device according to the present invention includes a solar heat absorbing section provided in a window on the sunny side of the building, a radiator provided in a room or cold area on the shade side of the building, and the solar heat absorbing section provided in a window on the sunny side of the building. and a heat transport fluid conduit connecting the radiator and the radiator.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram of a first embodiment of the invention.

In the figure, 1 is a building, 2 is a window on the sunny side, and 3 is a window on the shaded side. The window 2 on the sunny side constitutes a solar radiation heat absorption section 4 which is a part of the device of the present invention. A circulation pipe 5 that circulates between the sunny side and the shaded side is provided inside the walls, ceiling, and floor of the building 1, and this circulation pipe 5 includes a solar heat absorption section 4 and a radiator 6 on the shaded side. It is connected. In addition, a check valve 7 is provided at a rising portion 9 on the sunny side of the circulation pipe 5.The circulation pipe 5 is filled with a refrigerant such as freon or a heat transport fluid such as prine. There is. As shown in FIGS. 2 and 3, the window 2 on the solar surface side that constitutes the solar heat absorption section 4 has a triple window structure, and has an outer glass 8, a heat ray absorbing glass 9, and an inner glass 10. However, a sealed space S1+82 is formed between these window glasses. The upper frame 11 of these window glasses 8 to 10 is an intermediate member, as shown in FIG. A fluid port 14 and a fluid outlet 15 are provided so that fluid can pass therethrough, and a circulation pipe 5 is connected thereto.

Fins 16 are provided in the portions of the upper frame 11 facing the spaces S1 and S2, and are configured to efficiently transfer the heat of the high temperature air accumulated in the spaces S1 and S2 to the heat transport fluid within the upper frame 11. There is. The entire outer periphery of the upper frame 11 is covered with a heat insulating material 17 to prevent heat from dissipating into the outside air.

The lower frame 12 and side frames 13 are made of solid metal, similar to ordinary window frames, but insulation materials 18 and 19 are filled in the grooves into which the peripheral edges of the window glass are inserted. The structure is such that heat from the window glass does not escape to the respective metal parts of the lower frame 12 and side frame 13.

The radiator 6 is an air-cooled heat exchanger, and is equipped with a fan or guide vane that can be reciprocated in the forward and backward directions. (not shown) is designed to rotate forward or reverse in response to detection signals from temperature detectors (not shown) installed in the sunny side of the room and the shaded side of the room.For example, the temperature inside the sunny side of the room changes. When the temperature is higher than the indoor temperature on the shade side, it rotates in the normal direction and releases the heat inside the radiator 6 into the room, but when the indoor temperature is 2.
When the temperature exceeds 7℃, the reverse occurs and the hot air inside the radiator is discharged to the exhaust pipe 20.
It operates to exhaust air out of the building through the

In addition, as shown in FIG. 3, it is a good idea to insert a heat insulating material 21 between the contact surfaces of the upper frame 11 and the side frames 13 to prevent the heat from the upper frame 11 from escaping to the side frames 13. Next, the operation of the apparatus of the present invention configured as described above will be explained.

When sunlight enters the window 2 on the sunny side, the heat rays in the sunlight are absorbed by the heat ray absorbing glass 9, and only the spectral parts other than the heat rays are absorbed by the heat ray absorbing glass 9 and the inner glass 10.
It passes through and enters the room on the sunny side. The temperature of the heat ray absorbing glass 9 that has absorbed the heat rays becomes quite high, and the air in the spaces S1 and S2 is thereby heated by the heat ray absorbing glass 9, creating an upward air current within the spaces Sl and S2. Therefore, heat is carried to the top of the space 51182 and the upper frame 1
1 is heated, but since the fins 16 are cooled by the heat transport fluid in the upper frame 11,
Space S1. The heat within S2 is transferred to the heat transport fluid within the upper frame 11. As a result, when the heat transport fluid is heated, it rises in the circulation pipe 5, reaches the upper transverse pipe section in the ceiling, and further passes through the upper transverse pipe section to reach the shaded side of the building. . Therefore, the heat transport fluid flows down the descending pipe section of the circulation pipe 5 and enters the radiator 6, and after dissipating heat in the radiator 6, it passes through the lower transverse pipe section under the floor and enters the rising pipe section on the sunny side. Enter the bottom end. Then, the heat transport fluid gradually rises up the rising pipe section due to the pressure of the subsequent heat transport fluid flowing from behind, but since this rising pipe section is provided with a check valve 7, the heat transport fluid flows backward. The liquid is pushed up without any movement and flows into the upper frame 11 of the window 2 on the sunny side again. As mentioned above, the fan installed in the heat radiator 6 rotates cartwheel according to the temperature detectors installed in the room on the sunny side and the room on the shaded side, and releases the heat released from the heat transport fluid into the room on the shaded side. However, when the indoor temperature on the shaded side exceeds 27° C., the situation is reversed and nuclear heat is released outside the building 1 through the exhaust pipe 20.

As described above, according to the present invention, a new method and device for temperature balancing in a building can be achieved by utilizing all the heat incident on windows, which has conventionally been an obstacle to uniform temperature distribution in a building. is provided.

FIG. 4 shows a second embodiment of the invention. In this embodiment, a heat exchange part n is provided in the circulation pipe 5 on the sunny side, and the solar heat absorption part 4 is connected to the circulation pipe 5 via a heat transport body 23 inserted into the heat exchange part n. ing. Further, a radiator 6 installed in the room on the shade side is provided in the upper transverse pipe part of the circulation pipe 5, and a heated air pipe 24 is connected to the radiator 6, and the end of the heated air pipe is connected to the radiator 6. An indoor air outlet is provided.

An indoor temperature detector (not shown) is installed in the middle of the heated air pipe 5.
The exhaust pipe 2 is provided with a switching valve 26 controlled by the switching valve 26 and branched from the heated air pipe 5 via the switching valve 26.
7 is provided, and the exhaust pipe n opens to the outside of the building 1. The heat transporter connecting the heat exchange part n of the circulation pipe 5 and the solar heat absorption part 4 may be, for example, a heat pipe, but it is configured as a refrigerant circulation pipe that circulates a refrigerant such as Freon. It's okay. When a heat pipe is used, one end of the heat pipe is entirely housed within the upper frame 11 of the window 2, and a heat tube is drawn out from within the upper frame 11 in place of the circulation pipe 5 shown in FIG.

In addition, in FIG. 4, 7 is installed in the rising pipe part of the circulation pipe 5.
1, which is the same as the embodiment of FIG.

The operation in the second embodiment is as follows.

That is, when the air in the spaces 81 and 82 is heated by the sunlight entering the window 2 on the sunny side, and the heat is transferred to the refrigerant or heat tube in the upper frame 11,
Heat is transferred to heat transporter 2, which is a heat pipe or refrigerant circulation pipe.
3 and enters the heat exchange section 22 of the circulation pipe 5 and is transferred to the heat transport fluid in the circulation pipe 5, and then transferred to the cooling air in the radiator 6 on the shade side due to the movement of the heat transport fluid. Dissipated. The air heated in the radiator 6 enters the heated air pipe array 9, passes through the switching valve 26, and is blown out from the indoor air outlet 5 into the room on the shade side. As a result, the indoor temperature on the shaded side gradually rises. The switching valve prevents communication between the radiator 6 and the exhaust pipe 27 when the indoor temperature on the sunny side is higher than the indoor temperature on the shaded side and the indoor temperature on the shaded side is 27°C or less. When the indoor temperature on the surface side becomes equal to the indoor temperature on the shade side, or when the indoor temperature on the shade side exceeds 27°C, the radiator 6 and the exhaust pipe n are communicated, and the radiator 6 is connected to the indoor air outlet or the shade. The indoor temperature on the side is 27'c'
i, the heat absorbed by the window 2 on the sunny side is transferred to the exhaust pipe γ
is discharged to the outside of the building 1 through the On the other hand, the heat transport fluid that has become low temperature by releasing heat in the radiator 6 is transferred to the circulation pipe 5.
It flows down the downcomer pipe section, enters the downward transverse pipe section, reaches the lower end of the riser pipe section on the sunny side, and is gradually pushed up within the riser pipe section.

In this second embodiment, since the radiator 6 is provided in the upper transverse pipe section of the circulation pipe 5, the flow velocity of the heat transport fluid within the radiator 6 is slowed down, but on the other hand, there are no flow obstacles in the descending pipe section. Therefore, the descending speed of the heat transport fluid in the downcomer pipe section becomes faster, and therefore, the rate at which potential energy in the downcomer pipe section is utilized as push-up energy in the riser pipe section increases. Furthermore, if a heat pipe is used as the heat transporter connecting the heat exchange part n of the circulation pipe 5 and the solar heat absorption part 4, the heat transport efficiency will be high and the structure will be simple.

The embodiment shown in Figure 5 utilizes the heat that was discarded outside when the indoor temperature on the shaded side in the previous embodiment exceeds 27°C (this is mainly the temperature in summer) for cooling purposes, etc. It was designed to do so. In FIG. 5, the line is a heated water supply pipe connected to the generator of the absorption chiller and the water heater, and the heated water supply line is provided with a heat exchanger 4, and the heat exchanger 4 is connected to a branch pipe blade for heating air pipe feeding through a switching valve 26f (the switching valve 26 and other parts are the same as the embodiment shown in FIG. 4). Therefore, in the summer when the indoor temperature on the shaded side is 27°C or higher, or when the indoor temperature on the sunny side and the indoor temperature on the shaded side become equal, the switching valve is turned off and the radiator 6 and heat exchanger 4 are turned off. The heated air generated from the radiator 6 enters the heat exchanger 4 and heats the water flowing into the heated water supply pipe y. Therefore, the excess solar heat absorbed by the window 2 on the sunny side is used as the operational energy key for the absorption refrigerator and as hot water for hot water supply, which not only equalizes the temperature distribution within the building but also contributes to other This will also bring great benefits in terms of energy savings.

In the embodiment shown in FIG. 6, the circulation pipe is omitted and the solar heat absorption section 4 is
and a radiator 6 are connected by a heat pipe 31 (the other parts are the same as those shown in the embodiment of FIG. 5, so the explanation will be omitted). Therefore, this embodiment has a simpler configuration than the previous embodiments. Note that if the heat pipe 31 is laid so that it is lower on the sunny side and higher on the shaded side, the refrigerant liquefied in the radiator 6 will easily return to the heat absorption part side.

In the embodiment shown in FIG.
A solar heat absorption section 4 and a radiator 6 are connected to both ends of the circulation pipe 5, as in the embodiment shown in FIG.

In this embodiment, a refrigerant or pline circulation pipe 5 is used in place of the heat pipe 31 of the previous embodiment, so its operation is the same as that of the embodiment shown in FIG. (
Note that in the figures, parts indicated by the same reference numerals as in FIGS. 1 to 6 are the same parts as in FIGS. 1 to 6. ) The embodiment shown in FIG. 8 is a modified embodiment of FIG. 7, and is an embodiment in which a solar heat collector 32 installed on the outer wall or roof of the building 1 is connected to the heated water supply pipe. . When the solar heat collector 32 is installed on the roof, since the hot water temperature does not become very high in buildings etc., the hot water is further heated using solar radiation heat and the heat absorbed in the heat absorbing section 4, thereby further increasing the amount of water for hot water supply. It can reach high temperatures and supply more operating energy to the refrigerator. The operation of the embodiment shown in FIG. 8 is the same as that of the embodiment shown in FIG. 7 and the embodiment shown in FIG. 5, so a description thereof will be omitted.

As described above, according to the present invention, the uneven temperature distribution inside the building can be corrected by utilizing solar heat from the windows, which conventionally caused uneven temperature distribution inside the building. A novel method and apparatus for temperature balancing in a building is provided that can improve the livability of a room and save on air conditioning energy and the like.

Note that the structure of the solar heat absorbing section can be modified in various ways other than the illustrated embodiment, and the present invention is not limited to the structure of this embodiment. A pump may also be provided in the circulation line to increase the flow rate in the line.
