Description

  The present invention relates to an air conditioning apparatus with a low energy cost and a simple structure for controlling the room temperature of a house by suppressing waste of artificial energy such as oil, gas, and electricity and effectively utilizing sunlight and geothermal heat in the ground.

  Conventional room temperature adjustment in small houses has been using air conditioners in the summer and cooling and heating using energy such as electricity, gas, and oil in the winter. From the viewpoint, it is an urgent need to reduce CO2 emissions accompanying energy consumption, and reduction of energy consumption and further replacement with natural energy are urgently desired.

  Along with this, as a means of utilizing natural energy, what is currently widely used is a solar water heater (thermal efficiency 50-60%) and solar power generation (conversion efficiency 10-15%) using solar energy. However, in both cases, energy-saving technology that uses only solar energy is easily affected by the weather and cannot be used alone because of instability, and has been used in combination with other energy. There is a need for improvements.

  On the other hand, the underground 4 to 5 m underground maintains a stable temperature throughout the year, so that it is cooler than the outside air in the summer and warmer than the outside in the winter. For this reason, facilities that use geothermal heat have been experimentally constructed in large buildings and public facilities, but the method of use is to preserve the ice made in nature during the winter. In general, it is common to transfer the ice to a heat storage tank in the basement in the summer to make cold water, circulate the cold water to each room and cool it. Therefore, it was necessary to replenish the heat storage layer with ice, which was not suitable for small-scale housing.

Furthermore, a heat pump system that uses geothermal heat is also used to supply hot water in the home and to cool and heat the room, but a horizontal loop system (deep a 1-2 m deep moat in the ground, In order to obtain a heat source for a house with a floor area of 100 m ² , it is necessary to embed a 400 to 600 m heat collecting pipe, and a vertical loop system (ground) 2 holes are needed for digging 50-50m deep wells, and pipes for heat collection are buried in them, and it costs 3 to 5 million yen for general housing, and the heat pump is operated. There was a problem that the cost (electricity cost) was about 75% of that of an electric water heater using midnight power.

  In July 2003, the Building Standards Law was amended to require 24-hour ventilation of the room (to ventilate 0.5 times the volume of the room in one hour) as a “sick house measure”.

Therefore, the present applicant has invented and applied for an “earth / solar system (two-layer type)” described in Patent Document 1 and capable of complying with the Building Standard Law. According to the present invention, two tanks, a water storage tank and a hot water storage tank, are buried in the ground, and heat exchange pipes that communicate with the 24 hour air supply pipes of each room from the outside air intake are provided in both tanks. Plumbing and filling the storage tank with rain water, ground water or tap water, filling the storage tank with hot water from the solar water heater, and operating the opening / closing valve provided in the heat exchange pipe in the summer, in the winter Using cold water in the storage tank that has been cooled with cold outside air, the outside air is passed through the heat exchange pipe in the storage tank, and the hot outside air is cooled and sent to each room, so efficient cold wind operation can be performed I can do it. In the winter season, warm water in the water storage tank that has been warmed by hot outdoor air in the summer is warmed to the low temperature water via the heat exchange vapour. Since it passes through the heat exchange pipe, it became possible to send warm air into each room.
Japanese Patent Application No. 2007-42895

  However, in the invention of Patent Document 1 filed by the present applicant, two tanks, a water storage tank and a hot water storage tank, are required, so the piping becomes complicated, the number of open / close valves increases, and the price increases. A long construction period was also required.

Therefore, the present applicant invented and filed an application of “earth / solar system (single layer type)” described in Patent Document 2. According to the present invention, a concrete tank constructed integrally with the foundation of the building is built in the lower part of the building, and the heat exchange pipe is piped in the concrete tank, and the inside of the concrete tank is rainwater, or Filled with tap water or groundwater, the supply air from the total heat exchange type exhaust fan was led to the heat exchange pipe in the concrete tank, and in the summer, the supply air from the total heat exchange type exhaust fan was cooled by underground heat The water in the concrete tank and the heat exchange pipe are cooled and cooled, and then supplied to each floor via the air supply pipe. In the winter, the hot water from the solar water heater is supplied to the concrete tank. It is circulated into the concrete tank to make the inside of the concrete tank warm, and the supply air from the total heat exchange type exhaust fan is led to the heat exchange pipe in the concrete tank to heat and heat the concrete tank. After warming to heat exchange with the conversion pipe, by which the air supply to each floor through the supply pipe, it becomes possible to feed the hot air in each room.
Japanese Patent Application No. 2008-134783

  However, in the invention of Patent Document 2 filed by the present applicant, a concrete tank is required in the ground below the building, so that it is expensive and requires a long construction period.

Therefore, the present applicant invented and filed an application of “Earth Solar System (Ground Heat Recovery Pipe System)” described in Patent Document 3. According to the present invention, there is provided a total heat exchange type ventilation fan installed in a room of a building without installing a vent hole to the outside at the foundation of the building and blocking the air inside the first floor under the outside air to be in a sealed state. Fresh outside air supplied to the inside is sent to the inside of the first floor under the building, and a plurality of underground heat recovery pipes with a U-shaped lower part formed on the foundation floor under the first floor, both ends of the floor below the foundation floor. It is buried in the ground so as to protrude into the section, a blower is attached to one end of the underground heat recovery pipe, and the air inside the first floor is sucked into the underground heat recovery pipe by operating the blower, and the underground The air sucked into the heat recovery pipe is warmed in the ground heat recovery pipe by the underground heat in the winter season, and further, the hot water warmed by the solar water heater is circulated in the hot water heat storage tank provided at the bottom of the first floor Let the air inside the first floor under the floor warm, and summer Does not circulate the hot water from the solar water heater in the hot water storage tank provided at the bottom of the 1st floor, and the air cooled by the underground heat recovery pipe is supplied to the inside of the 1st floor under the ground heat. Warm air that is heated slightly in winter by supplying air under the first floor into the ceiling of each floor through the duct, and supplying the air from inside the ceiling to the room from the gallery installed in the ceiling of each room Can be sent to each room, and cool air that has been weakly chilled in the summer can be sent to each room.
Japanese Patent Application No. 2009-158863

  However, even in the invention of Patent Document 3 filed by the present applicant, when the rainy or cloudy day continues, the temperature of the hot water of the solar water heater does not rise, and the temperature difference between the rainy and cloudy day and the sunny day The problem that is large occurred.

Therefore, the present applicant invented and applied for “earth / solar system (ground heat recovery pipe system)” described in Patent Document 4. According to the present invention, in the winter season, a ventilation hole connected to the outside of the building is not installed in the base of the building, and the air inside the first floor is shut off from the outside air to be in a sealed state, and is installed in the building room. Fresh outside air supplied to the indoor side by the indoor ventilation fan is sent to the lower part of the first floor of the building, and a plurality of underground heat recovery pipes with U-shaped lower parts formed on the base floor under the first floor, both ends of the base floor It is buried in the ground so as to protrude below the first floor, and a blower is attached to one end of the underground heat recovery pipe. By operating the blower, the air inside the first floor is sucked into the underground heat recovery pipe. Because it was heated in the underground heat recovery pipe by the underground heat and warmed the air inside the floor under the first floor, and after using the hot water from the solar water heater in the bath, it was poured into the hot water storage tank, Even if it continues to rain or cloudy, 1st floor below It is possible to warm the temperature of the air without relying only on underground heat, and by reusing the energy of the remaining hot water in the warm bath that has been flowing through the drainage drainage, the interior of the floor under the first floor is lightly heated. Warm air can be supplied to each room. Also, in summer, the remaining hot water from the bath is not supplied to the hot water storage tank, and the outside air sent from the total heat exchange ventilator to the interior of the first floor is cooled in the underground heat recovery pipe by underground heat. After being mixed with the air in the lower floor of the first floor, the duct blower provided inside each floor ceiling is operated to send it from the interior under the first floor via the duct to the ceiling interior of each floor and install it on the ceiling. It became possible to cool the room by supplying air to the room.
Japanese Patent Application 2010-56088

  However, even in the invention of Patent Document 4 filed by the present applicant, there remains a problem in the long-term durability of the hot water heat storage tank installed under the floor, and the heating effect is insufficient only with the remaining hot water of the bath and the underground heat in winter. Such a problem occurred.

In addition, in the case of the geopower system described in Patent Document 5, which is conventionally known as a building air-conditioning ventilation system using a geothermal heat exchanger, in the winter season, only the underground heat alone can produce a heating effect (even underground 5m underground). Because the temperature is around 18 degrees, even if the outside air is warmed by underground heat, the temperature is only lower than that) and the price is high, so there was a problem in terms of cost when constructing a general house .
JP2007-303693A

Furthermore, in the case of the OM solar described in Patent Document 6, which is known as a solar system that uses solar energy, the heating effect is reduced when a rainy or cloudy day continues, so an auxiliary heating device is required. There was a problem and the disadvantage that cold wind operation was not possible in summer.
JP 08-005161

  In view of such conventional drawbacks, the present invention aims at harmony with nature, suppresses waste of artificial energy such as oil, gas, electricity, etc., and reduces solar heat and underground heat. It is an object of the present invention to provide a cooling / heating device that effectively uses and adjusts the room temperature of a house, has a low energy cost, and has a simple structure.

  In the invention according to Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4 filed by the present applicant, the above-mentioned problem has occurred. Therefore, the Company newly improved the invention of Patent Document 4, In the winter season, we developed a new earth / solar system that sends air heated by a solar heat collector installed on the roof to the inside of the floor below the first floor. .

In order to solve this problem, the invention according to claim 1 sends fresh outside air supplied to the room by a total heat exchange type ventilation fan installed in the room of the building to the floor of the first floor of the building and below the floor of the first floor. The bottom of the base plate is 100mm in inner diameter with a U-shaped lower part, and the depth of the PVC heat pipe is 4m deep. The air inside the first floor is sucked into the ground heat recovery pipe, and the air sucked into the ground heat recovery pipe is In the winter, the ground heat recovery pipe is warmed by the underground heat to warm the interior under the first floor, and the black galvalume steel plate on both sides of the roof so that the gap between the roof and the heat collector is 3 cm. Folded into a U shape Bending and forming a 6 mm convex reinforcing bent portion on the surface of the heat collecting plate that receives sunlight to reinforce the heat collecting plate, and the upper end of the heat collecting plate is warmed by sunlight In order to collect air, a solar heat collector with a heat collecting box formed of black galvalume steel plate in a rectangular parallelepiped shape is installed, and the warm air inside the solar heat collector heated by sunlight is 230 sq.m per hour, blower In the first floor, the air is supplied to the interior of the first floor to warm the interior of the first floor, and the air inside the first floor is warmed to the interior of each floor to warm the interior.

Embodiment 1 of the present invention will be described below.
Embodiment 1 of the Invention

  1 to 7 show a first embodiment of the present invention.

  FIG. 1 is a three-dimensional explanatory diagram of a house 1 using the solar heat collector 3 and the underground heat recovery pipes 31, 35, 41, 43 of the present invention. Below, the air conditioning system of the house using solar heat and underground heat is demonstrated.

  FIG. 1 is a three-dimensional explanatory view of a house 1 incorporating an earth / solar system for easy understanding of the earth / solar system of the present invention. The solar heat collector 3 is installed on the roof 2, and the bottom of two PVC pipes (4m PVC pipes) are joined at the four corners of the foundation base 24 with a PVC 90 ° elbow and PVC pipe. 4 sets of PVC pipe underground heat recovery pipes 31, 35, 41, 43 constructed in a U shape (shown in the enlarged view of FIG. 2) so that both ends protrude from the foundation floor 24 into the interior below the first floor. A 90 ° elbow 25 and a 90 ° elbow 27 made of PVC are attached to the tip of the PVC pipe that is buried inside and protrudes into the first floor under the ground heat recovery pipe 31, and the tip of the 90 ° elbow 27 made of PVC. The blower 28 is attached to. Similarly, a PVC 90 ° elbow 33 and a 90 ° elbow 37 are attached to the tip of the PVC pipe protruding into the first floor under the ground heat recovery pipe 35, and the tip of the PVC 90 ° elbow 37 is attached to the tip of the PVC 90 ° elbow 37. A blower 38 is attached. Similarly, a PVC 90 ° elbow 15 and a 90 ° elbow 17 are attached to the tip of the PVC pipe protruding into the first floor under the ground heat recovery pipe 41, and the end of the PVC 90 ° elbow 17 is attached to the tip of the PVC 90 ° elbow 17. A blower 18 is attached. Similarly, a PVC 90 ° elbow 47 and a 90 ° elbow 48 are attached to the tip of the PVC pipe protruding into the first floor under the ground heat recovery pipe 43, and the tip of the PVC 90 ° elbow 48 is attached to the tip of the PVC 90 ° elbow 48. A blower 49 is attached, and the air intake and air outlet of a 90 ° elbow made of PVC attached to the two PVC pipes constituting the underground heat recovery pipes 31, 35, 41 and 43 are perpendicular to each other. The air discharge ports of the four adjacent ground heat recovery pipes and the air intake ports are arranged so as to face each other.

  Further, the air between the roof 2 heated by the heat collecting plate 4 of the solar heat collector 3 and the heat collecting plate 4 rises and is collected in the heat collecting box 5, and the blower 21 attached to the indoor duct 13 is operated. As a result, the outside air collected in the heat collecting box 5 is supplied from the outside air introduction duct 7 to the inside of the first floor under the indoor duct 13 attached indoors. In this case, the outside air inside the outside air introduction duct 7 attached to the heat collecting box 5 and surrounded by the heat insulating material is introduced into the room from the wall immediately below the roof 2 in order to prevent a temperature drop due to the cold outside air in the winter. The air is supplied into the interior of the first floor below the interior duct 13 surrounded by the material as indicated by the arrow 20.

  Furthermore, as shown in FIG. 6, by operating the blowers 18, 28, 38, and 49, the air inside the first floor under the suction of the underground heat recovery pipe 31 is indicated by the arrow in the underground heat recovery pipe 31. It flows in the direction of the arrow 29 from the 30 direction, the temperature is adjusted by underground heat, and is discharged to the inside of the first floor below by the blower 28. The air discharged into the first floor under the air is blown in the direction of the arrow 32 in this way, mixed with the air inside the first floor under the air, and adjusted so that the temperature becomes uniform, and again from the 90 ° elbow 33 made of PVC. It is sucked into the underground heat recovery pipe 35, flows through the underground heat recovery pipe 35 from the direction of the arrow 34 to the direction of the arrow 36, is adjusted in temperature by the underground heat, and is discharged to the inside of the first floor below by the blower 38. The air discharged into the first floor under the air in this way is blown in the direction of the arrow 55, mixed with the air inside the first floor under the air, adjusted so that the temperature becomes uniform, and again from the 90 ° elbow 47 made of PVC. It is sucked into the underground heat recovery pipe 43, flows through the underground heat recovery pipe 43 from the direction of the arrow 44 in the direction of the arrow 42, is adjusted in temperature by the underground heat, and is discharged to the inside of the first floor below by the blower 49. The air discharged into the first floor under the air is blown in the direction of the arrow 50 in this way, mixed with the air inside the first floor under the air, adjusted so that the temperature becomes uniform, and again from the 90 ° elbow 15 made of PVC. It is sucked into the underground heat recovery pipe 41, flows through the underground heat recovery pipe 41 from the arrow 40 direction to the arrow 39 direction, is adjusted in temperature by underground heat, and is discharged by the blower 18 to the inside of the first floor below. The air discharged into the first floor under the air in this way is blown in the direction of the arrow 22 and mixed with the air inside the first floor under the air so that the temperature becomes uniform, and again from the 90 ° elbow 25 made of PVC. It is sucked into the underground heat recovery pipe 31. In this way, the air intakes (the 90 ° elbows 25, 33, 47, 15 made of PVC) of the underground heat recovery pipes 31, 35, 41, 43 arranged at the four corners of the foundation bottom plate 24, and the underground heat recovery pipes By configuring the air outlets (90 ° elbows 27, 37, 48, and 17 made of PVC) to face each other, the air inside the first floor floor is mixed without being stagnated depending on the location inside the floor, The temperature of the air under the floor is adjusted so as to be uniform at any place.

  Furthermore, by embedding underground heat recovery pipes 31, 35, 41, 43 in the four corners of the foundation bottom 24 under the first floor, the heat generated from the underground heat recovery pipes in the underground can be It is possible to reduce the heat interference between the underground heat recovery pipes. In particular, when underground heat recovery pipes are embedded in a narrow area, the temperature of the underground changes due to heat interference between the underground heat recovery pipes (in the summer, hot underground air is sent to the underground heat recovery pipe In the winter, the cold outside air is sent to the geothermal heat recovery pipe to lower the temperature in the ground, and the merit of the geothermal heat recovery pipe is reduced.

  Thus, it became possible to efficiently collect the underground heat by attaching one blower to each of the underground heat recovery pipes 31, 35, 41, and 43 and recovering the underground heat. Furthermore, by installing one blower independently for each of the underground heat recovery pipes 31, 35, 41, 43, the temperature of the air inside the floor under the first floor is cooled (warm) in the beginning of summer (winter). ) If too much, only a few of the four underground heat recovery pipes 31, 35, 41, 43 are operated, and the operation of the other underground heat recovery pipes is stopped. It became possible to adjust the temperature. In our company, the earth / solar system using four sets of underground heat recovery pipes explained in the first embodiment of the present invention is a residential specification with a floor area of up to 40 tsubo, and the floor area of more than that In the case of the above-mentioned housing, the underground heat recovery pipe is added according to the floor area.

  In the present invention, a PVC pipe having an inner diameter of 100 mm is used for the underground heat recovery pipes 31, 35, 41, and 43, and the depth embedded in the underground is about 4 meters. The reason for this is that the standard length of PVC pipe is 4 meters, which is easy to obtain and inexpensive, and the temperature of 4 to 5 meters underground in the Kanto area changes from about 17 to 19 degrees Celsius throughout the year. Because there are few. By the way, at our showroom (with basement) in Oyada, Adachi-ku, Tokyo, we measure underground temperatures of 1 meter, 3 meters and 5 meters every day. The underground temperature is the lowest temperature of 17.1 ° C between May and June, and the highest temperature of 19.3 ° C between November and December. The reason why the minimum temperature of 5 meters underground is from May to June with respect to the lowest ambient temperature (around February) is because it takes time for the temperature of the ground surface to penetrate into the ground. The same applies to the summer season.

  In addition, when the underground heat recovery pipes 31, 35, 41, 43 are buried in the ground, an auger is attached to a small heavy machine (Aborigoshishasha, etc.), and a hole is dug in the ground with the auger. Since the underground heat recovery pipe is embedded, the construction period can be shortened and construction can be performed at low cost.

  In order to prevent moisture from accumulating inside the first floor under the first floor of a general house, the foundation of the foundation and the foundation are ventilated so that the outside air and the air inside the first floor under the floor are always ventilated. Although packing is used, in the present invention, in order to use the interior under the first floor as an outside air temperature adjustment tank, a solid foundation is constructed so that the outside air does not flow directly into the lower floor of the first floor. Use an airtight foundation packing between the foundations so that the interior under the first floor will be in a sealed state without venting to the outside air.

  With the configuration as described above, the low-temperature air operation of the room in winter in FIG. 2 will be described.

  First, in a general method of using a total heat exchange type exhaust fan, fresh outside air that has finished heat exchange inside the total heat exchange type exhaust fan is supplied to the living room. A method of supplying fresh outside air having been heat exchanged inside the heat exchange type ventilation fan to the inside 1 floor under floor 83 will be described. The room-side discharged air (contaminated room air) of the first-floor room A is sucked into the total heat exchange type ventilation fan 75 and exhausted from the hood 78 to the outside through the duct 77. At that time, the indoor air exhausted by the total heat exchanging ventilation fan 75 (indoor discharge air) and the outside air supplied from the hood 78 into the room (outdoor suction air) are heated inside the total heat exchanging ventilation fan 75. The outdoor intake air (fresh air) sucked by the total heat exchange type ventilation fan 75 is all supplied to the first floor lower interior 83 via the duct 86. Similarly, the indoor side discharge air (contaminated room air) of the room B on the second floor is sucked into the total heat exchange type ventilation fan 67 and exhausted from the hood 69 to the outside through the duct 68. At that time, the indoor air exhausted by the total heat exchange type exhaust fan 67 (indoor discharge air) and the outside air supplied to the room from the hood 69 (outdoor intake air) are heated inside the total heat exchange type exhaust fan 67. While being exchanged, all of the outdoor intake air (fresh air) sucked by the total heat exchange type ventilation fan 67 is supplied to the first floor lower interior 83 via the duct 71.

  Thus, by using the total heat exchange type exhaust fans 67 and 75, when the warm air in the room in winter is replaced (ventilated) with the cold outside air, the temperature of the warm air in the room is minimized. It is possible to limit to the limit. By the way, on the Mitsubishi Electric Corporation website, the heat exchange function of LOSSNAY (the product name of the total heat exchange type exhaust fan) is changed to “when the outside air temperature is 0 ° C., the room temperature is 20 ° C., and the temperature exchange efficiency is 75%” It is explained that when air at 0 ° C. is ventilated by LOSSNAY, the temperature of the outside air (0 ° C.) becomes 15 ° C. due to the action of the heat exchanger and is supplied to the room (fresh air).

  Subsequently, how the outside air (outdoor air sucked) from the total heat exchange type exhaust fans 67 and 75 supplied to the first floor lower interior 83 in this way is heat-exchanged in the first floor lower interior 83 and weakened. Explain whether it will be hot air.

  The outside air from the total heat exchange type ventilation fans 67 and 75 supplied from the ducts 71 and 86 is mixed with the air inside the first floor floor 83, and the blower 93 attached to the underground heat recovery pipe 92 is operated. The air in the first floor under floor 83 is sucked into the underground heat recovery pipe 92 from the direction of the arrow 91 and is warmed by the underground heat in the underground heat recovery pipe 92 to become low-temperature air. As shown in FIG. Similarly, by operating the blower 98 attached to the underground heat recovery pipe 96, the air in the first floor lower floor interior 83 is sucked into the underground heat recovery pipe 96 from the direction of the arrow 95, and the underground heat recovery pipe 96 In 96, it is warmed by the underground heat and becomes a low-temperature air, and is exhausted by the blower 98 to the first floor lower interior 83 as shown by the arrow 99 direction. Similarly, by operating the blower 101 attached to the underground heat recovery pipe 97, the air in the first floor lower floor interior 83 is sucked into the underground heat recovery pipe 97 from the direction of the arrow 100, and the underground heat recovery pipe In 97, it is warmed by the underground heat and becomes a low-temperature air, and is exhausted by the blower 101 to the first floor lower interior 83 as shown by the arrow 102 direction. Similarly, by operating the blower 108 attached to the underground heat recovery pipe 104, the air in the first floor lower floor interior 83 is sucked into the underground heat recovery pipe 104 from the direction of the arrow 103, and the underground heat recovery pipe In 104, it is warmed by underground heat and becomes a low temperature air, and is exhausted by the blower 108 to the first floor lower interior 83 as shown by the arrow 109 direction.

  Further, the air between the heat collecting plate 63 of the solar heat collector 62 mounted on the roof 66 and the roof 66 rises by sunlight and is collected in the heat collecting box 64, and the blower (described in FIG. 1). By operating the blower 21), the air is supplied to the first floor lower interior 83 via the outside air introduction duct 65 and the indoor duct (the indoor duct 13 described in FIG. 1) attached to the room. In this case, the outside air introduction duct 65 attached to the heat collection box 64 and kept warm by the heat insulating material is constructed so as to be introduced into the room from the wall surface immediately below the roof 66 in order to prevent a temperature drop due to cold outside air in winter. The air in the first floor lower interior 83 is further warmed by supplying it to the first floor lower interior 83 via the indoor duct kept warm.

  In this way, the outside air that has become a warm air in the first floor under floor 83 warms the first floor room A by warming the first floor, and the air in the first floor under floor 83 that has become a warm air is By operating the blower 82 attached below the first floor, air is supplied from the gallery 81 in the direction of arrow 80 to warm the first floor room, and further, the blower of the duct 117 piped from the first floor lower interior 83 to the second floor. By operating 114, the warm air in the first floor under floor 83 is supplied through the duct 117 in the direction of the arrow 72 from the gallery 118 to warm the second floor room B.

  Next, a description will be given of the operation of the cool air in the room in summer in FIG.

  First, in a general method of using a total heat exchange type exhaust fan, fresh outside air that has finished heat exchange inside the total heat exchange type exhaust fan is supplied to the living room. A method of supplying fresh outside air having been heat exchanged inside the heat exchange type ventilation fan to the inside 1 floor under floor 83 will be described. The room-side discharged air (contaminated room air) of the first-floor room A is sucked into the total heat exchange type ventilation fan 75 and exhausted from the hood 78 to the outside through the duct 77. At that time, the indoor air exhausted by the total heat exchanging ventilation fan 75 (indoor discharge air) and the outside air supplied from the hood 78 into the room (outdoor suction air) are heated inside the total heat exchanging ventilation fan 75. While being exchanged, all of the sucked outdoor outside air (fresh air) is supplied to the first floor lower interior 83 via the duct 86. Similarly, the indoor side discharge air (contaminated room air) of the room B on the second floor is sucked into the total heat exchange type ventilation fan 67 and exhausted from the hood 69 to the outside through the duct 68. At that time, the indoor air exhausted by the total heat exchange type exhaust fan 67 (indoor discharge air) and the outside air supplied to the room from the hood 69 (outdoor intake air) are heated in the total heat exchange type exhaust fan 67. While being exchanged, all the sucked outdoor outdoor air (fresh air) is supplied to the first floor lower interior 83 via the duct 71.

  In this way, by using the total heat exchange type exhaust fans 67 and 75, when the cool indoor air in the summer is replaced (ventilated) with the hot outdoor air, the rise in the temperature of the cool indoor air is minimized. It is possible to limit to the limit.

  Subsequently, how the outside air (outdoor air sucked) from the total heat exchange type exhaust fans 67 and 75 supplied to the first floor lower interior 83 in this way is heat-exchanged in the first floor lower interior 83 and weakened. Explain whether it will be cold.
