Description

  The present invention, in a building space that requires heating, cooling and 24-hour ventilation, can effectively use natural energy, while suppressing the energy consumption related to them, and can be realized at low initial cost and running cost. It is a solar heating / cooling ventilation device that facilitates maintenance and a solar heating / cooling ventilation method using the same.

  The thermal performance of buildings in Japan, which are scarce of petrochemical energy resources, is not sufficient from the viewpoint of energy saving, and the current situation is that they have been comforted by heating and cooling with kerosene and electric power. As part of measures to prevent global warming in recent years, it was considered to raise the thermal performance standards of buildings, and a gradual increase was made.

  FIG. 9 shows the transition of energy saving standards when a general house is assumed. In 1999, the energy saving standards for houses were strengthened, and in 2003, the installation of a 24-hour ventilation system became mandatory. As a result, the heat insulation performance and airtight performance of the building were further improved, and energy consumption related to heating and cooling was suppressed.

  On the other hand, for 24-hour ventilation, the third type ventilation that directly introduces outside air into the room is the mainstream, and although the heat load of the building excluding the ventilation load has decreased, the ventilation load does not change, so the proportion of the ventilation load is rather Doubled.

  Since Japan experienced two oil shocks, technological development using solar heat and sunlight became active. Hot water panels and solar cells are widely known as successful examples.

  Attempts to reduce the heating load of buildings using solar heat have been generalized as a direct gain method (passive solar) that captures solar heat indoors by taking a large glass window at a low cost and is easy for anyone to capture. .

Further, as a technique for more actively using solar heat, a solar floor heating and ventilation system (commonly referred to as OM solar) that guides air collected on the roof surface to the floor by a blower unit and discharges it from the floor to the room is the following patent document etc. It is in.
Patent No. 2626966 (Air cooling method using solar system house)

  The outline of the solar system house will be described with reference to FIG. 10. An air flow path 102 having a roof gradient is formed immediately below a roof plate 101 such as a color iron plate or a slate plate, and one end of the air flow channel 102 is provided at the eaves. The other end communicates with a ridge duct 104 as a heat collection box made of a heat insulating material.

  Inside, a backflow prevention damper 106, a fan 107, and a flow path switching damper 108 are provided, and one of the flow path switching dampers 108 on the outflow side is opened to an outdoor space by an exhaust duct 109 to a hut 122 that is an attic space. Installed, the inflow side of the backflow prevention damper 106 of the handling box 105 is communicated with the ridge duct 104, and the outflow side of the flow path switching damper 108 is connected to the upper end of the falling duct 110. The lower end of the falling duct 110 opened to the air circulation space 113 between the thermal storage soil concrete 111 as the underfloor heat storage body and the floor panel 112, and a floor outlet 114 from the air circulation space 113 to the room was provided.

  As described above, the inflow side of the backflow prevention damper 106 of the handling box 105 is connected to the ridge duct 104. The inflow side of the backflow prevention damper 106 is also connected to a circulation duct 119 that opens indoors through a ceiling or the like. The backflow prevention damper 106 is configured as a flow path switching damper for switching the flow path between the ridge duct 104 side and the circulation duct 119 side. In addition, if the room provided with the suction port 120 through which the circulation duct 119 opens is on the second floor, the room having the floor panel 112 provided with the floor outlet 114 to the room has a blow-off structure as air. It is desirable to make the flow freely.

  In the handling box 105, a hot water take-off coil 115 is provided between the backflow prevention damper 106 and the fan 107, and the hot water take-off coil 115 is connected to the hot water storage tank 117 by a circulation pipe 116. A hot water supply boiler 118 is provided on the way, and a hot water supply pipe 121 connected to a bath, a washroom, and a kitchen is connected.

  Thus, the roof board 101 which is a metal plate heated by sunlight warms the outside air that has entered the air flow path 102, and the warmed air rises along the roof gradient. Then, this heated air is collected in the ridge duct 104 and then enters the handling box 105 by the fan 107 and flows down from the handling box 105 through the falling duct 110 to flow air between the thermal storage soil concrete 111 and the floor panel 112. Enter the space 113. In this air circulation space 113, heated air directly warms the floor surface via the floor panel 112, stores heat in the thermal storage soil concrete 111, and is blown directly into the room as warm air from the floor outlet 114. The three types of heating are performed.

  On the other hand, the hot water coil 115 heats water fed from the hot water storage tank 117 through the circulation pipe 116 and stores it as hot water in the hot water storage tank 117, and from here the hot water supply boiler 118 for reheating as necessary. Then, it is reheated and hot water is supplied from the hot water supply pipe 121 to various places.

  In the solar system house using the heated air collected by sunlight as shown in FIG. 10, all the heated air heated by the roof plate 101 is released to the outside air at a high temperature such as summer and when heating is not necessary. It is necessary to throw it away. In that case, if the falling duct 110 side that is one of the outflow sides is closed by the flow path switching damper 108 and the exhaust duct 109 side that is the other outflow side is opened, the heated air is discharged from the handling box 105 to the exhaust duct. It is thrown away via 109. In addition, since the heated air passes through the handling box 5 to heat the hot water coil 115, it can be ensured that hot water can be obtained by using solar heat even at high temperatures such as summer.

  On the other hand, the backflow prevention damper 106 closes the circulation duct 119 side and opens the ridge duct 104 side, as shown in the case of heat collection during the daytime when heating such as summer is not necessary. Further, the flow path switching damper 108 closes the fan 107 and the falling duct 110 side, and connects the fan 107 and the exhaust duct 109 side.

  When the fan 107 is driven in this way, the heated air that has entered the roof shed 122 from the ventilation opening 125 and then collected in the ridge duct 104 via the air flow path 102 enters the handling box 105, and the hot water coil 115. After being heated, it flows through the exhaust duct 119 and is thrown away outdoors. At that time, the air sent directly from the fan 107 to the exhaust duct 109 gives an attractive force to the falling duct 110, and the air under the floor is sucked into the exhaust duct 109 through the falling duct 110, so that only ventilation of the hut 122 is performed. Moreover, ventilation under the floor can be performed at the same time.

  In the summer night, the backflow prevention damper 106 closes the circulation duct 119 side and opens the ridge duct 104 side in the same way as in the daytime. However, the flow path switching damper 108 includes the fan 107 and the falling duct 110. The fan 107 and the exhaust duct 109 side are closed.

  In this state, if the fan 107 of the handling box 105 is turned, the night cold air enters the roof shed 122 from the ventilation opening 125, and the air in the shed 122 is formed immediately below the roof plate 104 of the south roof. The air flow path 102 is entered, where radiative cooling is performed. Then, after being collected in the building duct 104, it enters the handling box 105, flows down from the handling box 105 through the falling duct 110, enters the air circulation space 113 between the thermal storage soil concrete 111 and the floor panel 112, and stores the heat. Cooling action is performed between the cold storage in the soil concrete 111 and the direct discharge into the room as cold air from the air outlet 114.

  The system of Patent Document 1 can be operated when outside air is introduced, that is, mainly during winter days (when the heat collection temperature is higher than room temperature) and summer nights (when the heat collection temperature is lower than room temperature). It is a condition, and other conditions require some heating and cooling equipment and a 24-hour ventilator.

  In the case of a house where the former facilities are essential but the latter is obliged to provide 24-hour ventilation, a 24-hour ventilation device is required separately from this, resulting in an increase in installation costs.

  Also, if you encounter a power outage for some reason during the summer day or have to stop due to a system failure, the metal plate directly under the glass plate on the roof heat collection surface will be over 100 ° C, As a result, the durability and strength of building materials will be adversely affected.

  On the other hand, although the heating load in winter decreases due to the recent global warming, the cooling period and the cooling load increase, and there is a concern that the supply of power will be insufficient every year.

  Also, it plays an important role as one of the solutions such as hay fever (cannot enter from outside) and sick house (take out polluted air), 24 hours with small initial load, running cost and heat load such as warming the outside air Realization of ventilation is desired.

  The object of the present invention is to solve the disadvantages of the above-mentioned conventional example, and is low in an optimal combination with the minimum heating and cooling equipment essential for realizing a comfortable indoor environment while actively using natural energy including solar heat.

Arrange multiple units in parallel so that the whole is a large panel, adjust the ventilation resistance so that air is evenly sucked in, suck air from the space on the side that receives solar radiation into the thin ventilation layer, Installed on the wall where sunlight can be received, an external air introduction heat collection unit that exchanges heat by convection or conduction with the radiant heat received while passing through the ventilation layer, and blows out the heat exchanged to the side opposite to the side receiving solar radiation, This outside air introduction heat collection unit The heat storage layer provided on the underfloor space communicating further, it is an Abstract that it has established a heating and cooling unit on the floor near.

  According to a fifth aspect of the present invention, as a solar heating / cooling ventilation method using the apparatus according to the first aspect, outside air heated by an outside air introduction heat collecting unit is introduced under the floor during the day when heating is required, When the required room temperature is not reached, such as at night, the room air is sent to the floor while warming through the heating / cooling unit, and cooled by the outside air introduction heat collecting unit when cooling is necessary. The idea is to introduce fresh air under the floor, let the heat storage layer in the underfloor space cool down, and then release it into the room, and if it does not meet the required room temperature, such as during the day, send the room air to the floor while cooling it through the heating / cooling unit. Is.

  According to the first and fifth aspects of the present invention, by combining the outside air introduction heat collecting unit, the underfloor space having the heat storage layer, and the heating / cooling unit installed in the vicinity of the floor, it is close to a horizontal row with little vertical difference. The arrangement can be combined with the apparatus, and the conveyance duct when introducing the heat collection air under the floor can be greatly shortened. This has great merit not only for reduction of construction labor and cost but also for ease of maintenance. In addition, by installing the outdoor air introduction heat collecting unit on the wall surface, unnecessary heat collection in summer can be suppressed while securing useful heat collection in winter compared to the conventional technology installed on the roof surface.

  Furthermore, by installing the heating / cooling unit in the vicinity of the floor, the blown air from the heating / cooling unit can be sent directly under the floor.

  The gist of the present invention described in claim 2 is that the outside air introduction heat collecting unit is installed within 90 degrees east and west and at an inclination angle of 45 degrees or more with respect to the south surface.

  According to the second aspect of the present invention, the installation conditions are for obtaining more solar heat receiving effect during the winter day, but the installation is within 90 degrees east to west and at an inclination angle of 45 degrees or more with respect to the south surface. In the summer day, the solar altitude is high and the outdoor air collecting unit is prevented from becoming excessively hot.

  The gist of the present invention described in claim 3 is that a material having a relatively large heat capacity such as concrete, a water bag, or a latent heat storage material is used as the heat storage layer.

  The gist of the present invention described in claim 4 is to install an air conditioner indoor unit as the heating / cooling unit.

  According to the present invention as set forth in claim 4, heating and cooling can be performed with one facility, and it is most suitable as the cheapest facility with easy maintenance.

  According to the sixth aspect of the present invention, when the outside air warmed by the outside air introduction heat collecting unit is introduced under the floor during the day when heating is required, if the introduced air is cooler than the under floor, it is discharged into the room while being warmed by the heat storage layer. In the night when cooling is necessary, the gist is to introduce the outside air cooled by the outside air collecting unit into the floor, and if the introduced air is warmer under the floor, it is discharged into the room while being cooled by the heat storage layer. .

  According to the sixth aspect of the present invention, during the day when heating is required, when the introduced air is cooler than the floor, it can be discharged into the room while being warmed by the heat storage layer. Therefore, the room does not become cold by ventilation. In addition, when the introduced air is warmer under the floor at the time of cooling, it can be discharged into the room while being cooled by the heat storage layer, so that the room is not heated by ventilation.

  As described above, the solar heating / cooling ventilation device and the solar heating / cooling ventilation method using the solar heating / cooling ventilation method according to the present invention can be used for the minimum heating / cooling equipment while actively using solar heat and the winter warm and cool summer floor space. With this configuration, a more comfortable space can be realized while ventilating the building interior throughout the seasons for 24 hours.

  In addition, by combining an outdoor air introduction heat collection unit, an underfloor space with a heat storage layer, and a heating / cooling unit installed near the floor, the device can be combined in a horizontal arrangement with little vertical difference, and the collected air can be placed under the floor. It is possible to greatly shorten the transport duct when it is introduced into the machine, which not only saves labor and cost but also facilitates maintenance.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1-4 is explanatory drawing which shows embodiment of this invention, and assumes a normal house. It is desired that the heat insulation performance of the house of the present invention is 2 (W / m ² K) or less in terms of heat loss coefficient, and the airtight performance is 2 (cm ² / m ² ) or less in terms of substantial gap area. In buildings with poor thermal insulation, the heating / cooling load is large, making it difficult to effectively use the collected energy, and in buildings with poor airtightness, not only increased heating / cooling load but also stable planned ventilation is not possible. It is.

  In particular, the underfloor space 4 needs to ensure heat insulation of the foundation portion in contact with the outside air and its surroundings, and sealing of the gap between the foundation and the foundation. Thus, the underfloor space 4 can be regarded as the same indoor space as the living room.

  In the figure, reference numeral 1 denotes an outside air introduction heat collecting unit attached to a wall surface, which can be the one disclosed in Japanese Patent No. 4171014 previously invented by the inventor.

  As shown in FIG. 5 to FIG. 6, the outside air introduction heat collecting unit 1 has a distance of about 10 mm or less between a heat receiving plate 12 that is a plate material on the opposite side to a heat receiving plate 11 that is a plate material on the side receiving solar radiation. It is the flat panel-shaped plate-shaped body 50 arrange | positioned in parallel with the ultrathin air-permeable layer 13 interposed. The plate-like body 50 can also have a curved surface shape. It is also conceivable to provide the heat receiving plate 11 on both sides.

  Although the ultrathin air-permeable layer 13 is a thin air-permeable layer, the contact efficiency between the heat receiving plate and the flowing air is improved and the heat exchange performance is improved, but approximately 2 mm is preferable. (However, if the treatment air volume is greatly different, the height of the ventilation layer also changes.)

  The material constituting the plate-like body 50 is not particularly limited as long as the material has relatively good thermal conductivity, but the heat receiving plate 11 may be a black metal plate, a selective absorption film plate, or the like as a heat collecting surface material. Is preferred. Note that a solar cell can also be used as the heat collecting surface material of the heat receiving plate 11. The ability to cool the solar cell prevents the reduction in power generation efficiency.

  The plate-like body 50 has an air suction port 14 on the lower side and an air discharge port 15 on the upper side, and a connection allowance 16 is protruded from the upper end so that a plurality can be arranged.

  The plate-like body 50 has a vertical length of about 120 mm, but product variations are possible within a range of about 60 mm to 1800 mm. Also, the whole is of a horizontally long shape, and the whole heat receiving surface receiving solar radiation is arranged in parallel with a plurality of short lengths (several centimeters to 2 m) in the flow direction of the ultrathin vent layer 13. Arrange it so that it is a large panel, and adjust the ventilation resistance so that air is evenly drawn.

  The plate-like body 50 is used when it is installed on the wall surface 17 of the building, and the collective ventilation layer 18 is formed on the side opposite to the side receiving solar radiation (between the wall surface 17).

  Moreover, you may make it provide the material which permeate | transmits solar radiation, such as glass 19, with the air layer 20 in the side which receives solar radiation.

  The plate-like bodies 50 are arranged, the balance of airflow resistance of the ultrathin air-permeable layer 13 is taken into consideration, the air volume per area is set to the same level, and the divided heat collecting members (plate-like bodies 50) are evenly distributed. By adjusting so as to suck in, a usable temperature can be obtained on a small (short) heat exchange (heat collecting) surface.

  As shown in FIG. 7, the blower fan 3 is provided through the duct 2 to the outside air introduction heat collecting unit 1 which is a combination of a large number of parallel plate-like bodies 50 and the collective ventilation layer 18. Furthermore, it is possible to provide the indoor direct fan 30 via the introduction duct 35. Although illustration is omitted, the indoor direct fan 30 is separately attached with a hermetically closed type when stopped, and the blower fan 3 is separately attached with a damper when hermetically shut when stopped.

  In the figure, 34 is a parting edge (sheet metal winding) for installing the outside air introduction heat collecting unit 1 by combining the plate-like body 50 and the collective ventilation layer 18 in parallel with each other, and 38 is a base of the pneumatic solar heat collecting part. It is made of cement siding and painting. 37 is a ventilation layer, 36 is a base material + moisture-permeable waterproof sheet.

  A heat storage layer 6 was provided in the underfloor space 4 through which the outside air introduction heat collecting unit 1 communicated, and a heating / cooling unit 10 was installed near the floor. In the figure, 5 is a flooring material, 7 is an air outlet installed on the floor, 8 is a room, and 9 is a ventilation register attached to the wall of the room.

  As the heat storage layer 6, soil concrete can be used, but a material having a relatively large heat capacity such as concrete other than soil concrete, a water bag, or a latent heat storage material is used.

  An air conditioner indoor unit can be used for the heating / cooling unit 10.

  In this way, a plurality of plate-like bodies 50 as the outside air introduction heat collecting unit 1 attached to the wall surface that is the position to receive solar radiation are installed, and the outside air on the side that receives solar radiation by the plate-like bodies 50 is sucked into the air. The solar heat is collected by the ultrathin air-permeable layer 13 which is sucked from the mouth 14 and is a thin air-permeable layer, and the collected air blown out from the air outlet 15 of each plate-like body 50 is gathered by the air-collecting layer 18 and is collected by the blower fan 3 Supply to the underfloor space 4.

  The outside air introduction heat collecting unit 1 is arranged by arranging a plurality of plate-like bodies 50 in parallel, so that the heat exchange surface (collecting and radiating surface) is divided relatively finely, and the pneumatic heat exchange unit corresponding to the number of divisions is provided. Attached. Thereby, it is possible to balance the processing air volume, the ventilation resistance of the ultrathin ventilation layer 13 and the fan capacity of the blower 24.

  The outside air introduction heat collecting unit 1 is a thin ventilation layer, thereby improving the contact efficiency between the heat receiving plate and the flowing air, and improving the heat exchange performance to exchange heat with radiant heat by convection or conduction.

  The outside air can be efficiently warmed by the outside air introduction heat collecting unit 1. In the heat collecting unit with the glass 19, a heat collecting temperature of +30 to 40 ° C. can be obtained at the outside temperature in fine weather.

  FIG. 8 shows an application example in which the outside of the outside air introduction heat collecting unit 1 can be covered with a veil 51 of a plant such as a vine. The plant veil 51 is installed near the wall surface to prevent glare caused by solar radiation or to reduce the invasion of solar heat into the room. Water that elevates and evaporates from the plants cools the building walls. The plant veil 51 may be replaced by Yoshizu or the like.

  The glass 19 may constitute an atrium 52. As a planting louver for planting, the combination of the plant bale 51 and the atrium 52 is a louver that is laid horizontally and attached to a support, and a moss plant grows on a planting mat installed on the top surface of the slat. A structure capable of taking in air can also be used.

  The larger the area of the outside air introduction heat collecting unit 1 is, the higher the temperature can be collected, but since it is used for heating, it does not need to be excessively high. In that case, the amount of outside air introduced is increased to suppress the temperature. To adjust.

  Incidentally, the outside air introduction heat collecting unit 1 is installed within 90 degrees east and west and at an inclination angle of 45 degrees or more with respect to the south surface.

  The outdoor air introduction heat collecting unit 1 is installed under the condition of obtaining more solar heat receiving effect during the winter day, but should be installed within 90 degrees east and west and at an inclination angle of 45 degrees or more. Thus, it is possible to prevent the outdoor air introduction heat collecting unit from becoming excessively hot during the summer day.

  The air heated by the outside air introduction heat collecting unit 1 is sent into the underfloor space 4 by the blower fan 3 through the introduction duct 2, warms the flooring 5 and the heat storage layer 6 in the underfloor space 4, and performs floor heating and heat storage. It can be carried out. Further, air is discharged from the air outlet 7 installed on the floor surface to the room 8, and finally discharged from the ventilation register 9 or the like attached to the wall of the room to the outside.

  This series of air flows can also provide room ventilation. This ventilation is equivalent to type 2 ventilation because the room has a positive pressure compared to the outdoors, and has the advantage of preventing the intrusion of outside air, dust, pollen, etc. from invisible gaps in the building.

  FIG. 2 shows a second embodiment of the solar heating / cooling ventilation method at night in winter. As a matter of course, the heat collection temperature in the outside air introduction heat collecting unit 1 is almost the outside air temperature.

  Since the role of the outdoor air introduction heat collection unit 1 at night in winter is for the purpose of indoor ventilation, the amount of introduction outside air is about 0.5 (times / h) relative to the target space (during heat collection during the day Is sent to the floor 4 by the blower fan 3 through the introduction duct 2.

  The temperature of the air introduced under the floor at night in winter is usually lower than the flooring 5 and the heat storage layer 6 in the underfloor space, so it is slightly warmed by the flooring 5 and the heat storage layer 6 and installed on the floor surface. Air is discharged from the air outlet 7 into the room 8.

  If the required room temperature is not reached, the heating / cooling unit 10 installed near the floor is operated to warm the room air and return (circulate) it to the underfloor space 4 to realize heating.

  FIG. 3 shows a third embodiment of the solar heating / cooling ventilation method during the summer day. The outside air introduction heat collection unit 1 attached to the wall has a high altitude of the sun and is shielded by heat from the eaves of the building or roof fence, etc., but the temperature rise is less than in winter, When the weather is fine, the outside air temperature becomes + 10 ° C. As a more proactive heat shielding measure, a method such as covering with a plant bale 51 or reed is extremely effective.

  Since the purpose of the outdoor air introduction heat collection unit 1 during the summer day is to ventilate the interior as in the winter night, the amount of the introduced outside air is about 0.5 (times / h) relative to the target space. Is introduced into the underfloor space 4 by the blower fan 3 through the introduction duct 2.

  The temperature of the air introduced under the floor during the summer day is usually higher than that of the flooring 5 and the heat storage layer 6 in the underfloor space, so that the air is slightly cooled by the flooring 5 and the heat storage layer 6 and Air is discharged from the installed outlet 7 into the room 8. If the required room temperature is not reached, the heating / cooling unit 10 installed near the floor is operated to cool the room air and return (circulate) it to the underfloor space 4 to achieve cooling.

  FIG. 4 shows a fourth embodiment of the solar heating / cooling ventilation method at night in summer. As a matter of course, the heat collection temperature in the outside air introduction heat collecting unit 1 is almost the outside air temperature.

  The air taken in by the outside air introduction heat collecting unit 1 passes through the introduction duct 2 and is sent to the underfloor space 4 by the blower fan 3 to cool the flooring 5 and the heat storage layer 6 in the underfloor space, and the air outlet 7 installed on the floor surface. The air can be discharged from the inside to the room 8 to obtain a cool feeling.

  If the outside air temperature is lower than the room temperature required at night in the summer, the air volume of the outside air is actively increased and the underfloor space 4, the flooring 5, the heat storage layer 6, and the room 8 are cooled, and the next day The rise in room temperature can be suppressed.

  Since the above embodiment is simple, it can be applied to a small space such as when a part of a building is renovated.

  The outside air introduction heat collecting unit 1 can be installed independently from the handrail of the veranda or the building as long as the installation condition of claim 2 is satisfied according to the surrounding situation of the building.
