Description

The present invention relates to an environmentally friendly building.

Recently, environmental issues such as air pollution and global warming have been raised, and in the field of architecture, there is an increasing demand for the design and construction of environmentally friendly buildings that are sustainable and coexist with natural energy. being explored. By effectively controlling heat and solar radiation and using natural energy such as sunlight, environmentally friendly buildings can maintain a comfortable indoor environment while reducing the amount of fossil energy used.

As a generally popular environmentally friendly building, heat collection panels are installed at and around the top of the roof ridge, and the outside air taken in from the eaves etc. is heated in the process of flowing along the roof slope in the roof space. A so-called solar heat utilization system is applied, in which air (warm air) that is further warmed by nearby heat collection panels is guided to the underfloor space of the building via heat collection pipes, and warm air is supplied from the underfloor space to each room of the building. There are cases. In this specification, a system for generating and supplying warm air using heat collecting panels will be referred to as a solar heat utilization system, and a system for obtaining electric power from solar panels installed on the roof will be referred to as a solar power generation system. .

Solar heat utilization systems take advantage of the property of warmed air flowing as an upward current. Therefore, it is common to install heat collection panels at the top of the roof or around it, and the space under the floor. After the warm air is supplied, it is common that the warm air is blown upward from the floor surface of the first floor to each room.

Here, with reference to FIG. 1, a building to which a conventional solar heat utilization system has been applied will be described. FIG. 1 is a schematic diagram of a two-story building 10 with a gable roof.

The roof 1 of the building 10 has one ridge top 2, and a heat collecting panel 7 is installed around the ridge top 2 on the roof 1. The outside air taken in from the eaves 1a in the X1 direction is warmed during the circulation process, guided to the ridge top 2, and further warmed by the heat collection panel 7. A heat collection pipe 8 extending from the heat collection panel 7 to the underfloor space 4 is disposed inside the wall 3, for example.

Warm air in the attic space around the ridge top 2 is led to the underfloor space 4 in the X3 direction via the heat collection pipe 8, and is diffused horizontally in the underfloor space 4 in the X4 direction. The warm air diffused in the underfloor space 4 is supplied to the living room R1, the staircase K, etc. on the first floor in the X5 direction through the air outlet 5 on the floor of the first floor. The warm air is further supplied to the living room R2, living room L, etc. on the second floor via the staircase room K and the like. In addition, a ventilation opening 6 is provided in the outer wall of each room, and the warm air that has circulated inside the building is exhausted at an appropriate timing, and the warm air that is newly generated by the heat collection panel 7 is passed through the underfloor space 4. It is circulated to each room.

As a conventional published technique, Patent Document 1 proposes an operation control method for solar heat utilization equipment. This method of controlling the operation of solar heat utilization equipment is based on a solar system in which a handling box as an indoor unit equipped with a damper and a fan is directly or indirectly connected to the roof heat collection section, and a duct from the handling box is guided indoors or into the underfloor space. The house is equipped with an outdoor unit and a hot water storage unit using a heat pump, and a total heat exchanger and an air conditioning heat exchanger using a heat pump are installed in the handling box, which mixes ventilation air that exchanges heat between outdoor air and indoor air with indoor return air. As a condition for heat collection, when the temperature of the collecting air is higher than the air obtained by exchanging heat between outdoor air and indoor air through a total heat exchanger, the collecting air from the roof heat collecting section is taken in, and the handling box When the room temperature is lower than the set temperature, the ventilation air that has passed through the total heat exchanger and the indoor return air are mixed and sucked into the heat pump. When heating operation is performed using air conditioning heat exchanger, or when the room temperature is lower than the set temperature, and the temperature of the heat collecting air from the roof heat collecting section is higher than the air temperature passing through the total heat exchanger. Heating is performed using a heat pump's air-conditioning heat exchanger, and solar heat collection heating is conducted by leading indoors or to the space under the floor via a duct from the handling box. On the other hand, when the room temperature is higher than the cooling room temperature setting, a cooling operation is performed in which ventilation air that has passed through the total heat exchanger and indoor air are mixed and sucked in for heat pump cooling.

By having , two ridge tops can be obtained. Specific heat collection panels are installed at or around the top of these two buildings, and heat collection pipes are installed that extend from each heat collection panel to the first floor. There are multiple combinations of heat pipes, making it possible to use solar heat even more effectively.

Furthermore, by guiding warm air from the tops of multiple buildings to the first floor instead of the conventional underfloor space through their own heat collection piping, when the warm air diffuses into the underfloor space, it will not contain dust or dirt. This solves the problem of reduced cleanliness of warm air, making it possible to supply highly clean warm air from the first floor to the upper floors.

As a result, the heat load on the heating and cooling equipment in each room can be reduced.

Further, in another aspect of the environmentally friendly building according to the present invention,
A skip floor is provided between the first floor and the second floor below the flat roof or the third single-slope roof, and the warm air accumulation room is disposed below the skip floor on the outer wall side. It is characterized in that the circulating warm air clean room is arranged adjacent to the room and on the center side of the skip floor.

Note that in this specification and the drawings, substantially the same constituent elements may be given the same reference numerals to omit redundant explanation.

[Environmentally friendly building according to embodiment]
An example of an environmentally friendly building according to the embodiment will be described with reference to FIGS. 2 to 7. Here, FIG. 2 is a vertical cross-sectional view cut in the east-west direction, illustrating the configuration of a building forming an example of an environmentally friendly building according to the embodiment, and is a vertical cross-sectional view cut in the warm air accumulation room and a circulation cross-sectional view.

Further, FIGS. 6 and 7 are vertical cross-sectional views taken in the east-west direction and the north-south direction, respectively, illustrating the flow of warm air through the return pipe and resupply pipe extending from the circulation warm air clean room.

The building 100 forming the environmentally friendly building shown in FIG. 2 is a two-story building, and is a building of a steel frame structure, a reinforced concrete structure, a wooden structure, or a hybrid structure thereof.

The roof is of different types, including a first single-sided roof 21 having a roof slope on the west side, a second single-sided roof 22 having a roof slope on the east side, and a flat roof 23 located between the first single-sided roof 21 and the second single-sided roof 22. It has a mixed roof of 20. Here, the east side is a direction ranging from northeast to southeast, and the west side is a direction ranging from southwest to northwest.

In this way, since two types of single-sided roofs with different roof slopes are arranged with the flat roof 23 interposed between them, the first single-sided roof 21 and the second single-sided roof 22 have their own unique ridge tops. 25 and 26 are formed. Here, instead of the flat roof 23, it may be a heterogeneous roof including a separate third single-sided roof having a roof slope in the north-south direction. Each of the roofs 22 can have its own unique ridge top portions 25, 26.

It will be easier to understand by referring to FIGS. 2 and 3. In FIG. 2, a vertical cross-sectional view taken along line AA in FIG. 3 is shown on the left side of the center line CL of the building 100, and the center line CL A vertical cross-sectional view taken along line BB in FIG. 3 is shown on the right side of FIG.

The space below each of the first single-slope roof 21 and the second single-slope roof 22 includes an underfloor space 30C on the ground G, a first-floor living room 30A above the first-floor floor 31, and a second-floor living room above the second-floor floor 32. 30B are provided respectively.

On the other hand, in the space below the flat roof 23 in the center, skip floors 41 and 42 are provided between the first floor and the second floor, and at the middle level of the second floor, and above each skip floor 41 and 42, Holes 40A and 40B are provided. For example, both halls 40A and 40B are used for various purposes such as a living room, living/dining room, and bathroom. Further, in the space below this flat roof 23, there are stairs (rooms) connecting each floor.

As shown in FIG. 3, in the space below the skip floor 41 on the lower floor, a warm air accumulation chamber 50 is arranged in an area adjacent to one outer wall 35 (the south outer wall 35 in the illustrated example). In the central area of the space below the skip floor 41 adjacent to the skip floor 50, a circulating warm air cleaning room 60 is arranged.

An environmentally friendly building 200 in which heat collecting panels and solar panels are installed in the building 100 having such a roof configuration and room configuration will be described with reference to FIGS. 4 to 7.

Heat collecting panels 71 and 72 are attached around the ridge tops 25 and 26 of the first single-sided roof 21 and the second single-sided roof 22, respectively. The outside air taken in in the Y1 direction from the eaves 21a, 22a of the first single-sided roof 21 and the second single-sided roof 22 is gradually warmed as it flows in the Y2 direction along the roof slope, and reaches the ridge tops 25, 26. The heat collecting panels 71 and 72 further warm the air to generate warm air.

A unique heat collection pipe 75 extends from each heat collection panel 71 , 72 to the warm air collection chamber 50 . Since the ridge tops 25 and 26 and the heat collection panels 71 and 72 are provided at separate positions to the left and right (east and west) of the central hall space, the heat collection panels 71 and 72 are installed inside each of the left and right partition walls 36 of the hall space. Since the heat pipes 75 can be arranged, there is sufficient space for each heat collection pipe 75, and the installation work of both heat collection pipes 75 is not complicated with each other, good workability is guaranteed.

A ductless heat exchanger 77 is embedded in the partition wall 36 between the warm air accumulation room 50 and the first floor living room 30A, which is an adjacent room on the left and right (east and west) thereof. Furthermore, ventilation holes 78 are buried in the outer wall 35 at positions corresponding to the first floor living room 30A and the second floor living room 30B.

Warm air flows down in the Y3 direction through each heat collection pipe 75 extending from each heat collection panel 71, 72, is sent to the Y4 direction to the warm air accumulation chamber 50, and is accumulated there. Then, warm air is supplied from the warm air accumulation room 50 to the first floor living room 30A, which is an adjacent room, in the Y5 direction via the ductless heat exchanger 77.

The warm air supplied to the living room 30A on the first floor is supplied to each hall 40A, 40B via, for example, a staircase (room) in the central hall space, and is then supplied to the living room 30B on the second floor via, for example, the hall 40B on the upper floor. .

The warm air circulates within the building in this manner, and the warm air, which has been repurified and humidity-adjusted, is re-supplied via the humidity control unit 80 (see Figures 5 to 7) as described below. After such warm air circulation is performed within the building a predetermined number of times, the warm air is exhausted and an appropriate amount of outside air is supplied in the Y6 direction through the ventilation opening 78.

As shown in FIG. 4, a solar panel 73 is attached to the flat roof 23.

In this way, the environmentally friendly building 200 has a solar heat utilization system in which the heat collection panels 71 and 72 are attached to the single-sided roofs 21 and 22, respectively, and also has solar heat utilization systems on the flat roof 23 between them. By installing the panels 73, it will also be equipped with a solar power generation system, making it an environmentally friendly building that can make maximum use of natural energy.

In the environmentally friendly building 200, solar heat is utilized by supplying warm air to the first floor from heat collecting panels 71 and 72 specific to the two ridge tops 25 and 26 through heat collecting piping 75 extending to the first floor. There are a plurality of combinations of heat collection panels 71, 72 and heat collection pipes 75 that constitute the system, making it possible to use solar heat even more effectively.

Further, since the roof slopes of both the first single-sided roof 21 and the second single-sided roof 22 are in opposite directions, with the first single-sided roof 21 facing east and the second single-sided roof 22 facing west, , it is possible to collect heat by utilizing sunlight around sunrise and sunset, and it is possible to effectively bring in warm air in the morning and evening at the time of day when it is desired to be brought into each room.

In addition, since the warm air is led to the warm air accumulation chamber 50 below the skip floor 41 via the heat collection pipe 75 instead of to the underfloor space 30C, when the warm air supplied to the underfloor space 30C is diffused as in the conventional case. This solves the problem that the cleanliness of warm air decreases due to dust and dirt being contained in the air, and it becomes possible to supply highly clean warm air from the warm air accumulation chamber 50 to the adjacent chamber 30A and other chambers.

In addition, since the configuration does not take warm air into the underfloor space 30C and diffuse it horizontally, there is no need to increase the airtightness of the underfloor space 30C, which eliminates the time and effort required to take measures to improve the airtightness of the underfloor space. Costs can also be eliminated.

Furthermore, since the heat collection panels 71, 72 and the solar panel 73 are installed on separate (different types of) roofs, for example, multiple types of equipment work may become complicated (interference) when installing each panel. This allows the degree of freedom in fitting each panel to be increased, and it becomes possible to simplify the fitting of each panel.

Furthermore, by providing the hot air collection chamber 50 directly under the flat roof 23 located between each of the single-sided roofs 21 and 22, the entire length of the heat collection piping 75 leading from both single-sided roofs 21 and 22 to the warm air accumulation chamber 50 can be made as short as possible. Each heat collection pipe 75 can be shortened to The workability is also improved.

Further, a skip floor 41 is provided between the first floor and the second floor below the flat roof 23, and a warm air accumulation chamber 50 is formed in one room facing the outer wall 35 below the skip floor 41. By guiding the plurality of heat collection pipes 75 to the heat collecting pipe 50 and collecting the warm air, the warm air can be collected in a highly airtight room that utilizes the high airtightness and high heat insulation properties of the outer wall 35. That is, the outer wall 35 includes, for example, an outer wall surface material, a heat insulating board such as polystyrene foam, a heat insulating board such as a glass wool board, an outer wall frame, and a filled insulating material such as glass wool filled inside the outer wall frame, and is highly airtight. Forms walls with high thermal insulation properties. By effectively utilizing such an outer wall structure, the highly airtight warm air accumulation chamber 50 can be formed at the lowest possible cost.

The warm air accumulation room 50 collects warm air whose temperature has risen to a certain extent and supplies it to the living rooms 30A and the hall 40A on the first floor, so that when adjusting the temperature of each room, the adjusted temperature of each room and the warm air are adjusted. When comparing the temperature difference A and the temperature difference B between each room and the outside air, the temperature difference A can be made smaller than the temperature difference B, which leads to a reduction in the heat load on the air conditioning equipment in each room. Energy saving can be achieved. For example, if the outside air temperature is 0°C, the temperature of the warm air is 10°C, and the adjusted temperature of each room is 20°C, the temperature difference A will be 10°C and the temperature difference B will be 20°C. The effect of reducing the heat load on the heating and cooling equipment in each room is extremely high.

In addition, by providing the hot air collection chamber 50 on the first floor of the flat roof 23 between the single-sided roofs 21 and 22, the entire length of the heat collection piping 75 leading from both single-sided roofs 21 and 22 to the hot air accumulation room 50 can be increased. Since the heat collection pipes 75 can be arranged on different partition walls 36, the workability of the heat collection pipes is also improved.

In addition, a ductless heat exchanger 77 is embedded in the partition wall 36 between the warm air accumulation chamber 50 and the adjacent room 30A, and by supplying warm air purified by the ductless heat exchanger 77 to the adjacent room 30A, the heat exchange rate can be improved. Highly clean warm air can be supplied to the adjacent room 30A while suppressing the drop in temperature, and the warm air can also be supplied to other rooms via the adjacent room 30A. In the environmentally friendly building 200, warm air is collected in the warm air collection room 50 on the first floor instead of in the underfloor space 30C, so the cleanliness of the collected warm air is extremely high. By further increasing the cleanliness of the warm air through the filter of the ductless heat exchanger 77, it is preferable that extremely clean warm air can be supplied to the adjacent room 30A.

In addition, since the ductless heat exchanger 77 is embedded in the partition wall 36 between the warm air accumulation chamber 50 and the adjacent chamber 30A, the structure of the ductless heat exchanger 77 can be viewed from the warm air accumulation chamber 50 side or the adjacent chamber 30A side. Maintenance (washing, etc.) of elements such as filters and heat storage elements becomes possible.

As shown in FIGS. 6 and 7, a circulating hot air cleaning room 60 is disposed below the skip floor 41 below the flat roof 23 and on the center side of the skip floor 41 adjacent to the warm air accumulation room 50. .

The circulation warm air clean room 60 accommodates a humidity control and arousal unit 80, and is equipped with an air conditioner 89 (see FIG. 5), which is an example of heating and cooling equipment.

As shown in FIG. 6, a return pipe 83 and a re-supply pipe 84 extend from the humidity control and arousal unit 80 of the circulation warm air clean room 60 to each room, and a return pipe is connected to the suction port 86 embedded in the partition wall 36. 83 is connected, and a resupply pipe 84 is connected to an air supply port 85 buried in the partition wall 36.

Further, as shown in FIG. 7, an outside air intake pipe 81 and an exhaust pipe 82 extend from the humidity control and arousal unit 80 to the outer wall 35 via the warm air accumulation chamber 50.

The warm air supplied to each room flows through the return piping 83 in the Y10 direction and is returned to the humidity control and arousal unit 80, where it is cleaned again and the temperature and humidity of the warm air is adjusted again to the desired level. be adjusted.

The warm air, which has been cleaned and whose temperature and humidity have been adjusted by the humidity control and evacuation unit 80, flows through the resupply pipe 84 in the Y11 direction and is resupplied to each room in the Y12 direction.

In this way, after the warm air is recirculated a predetermined number of times using the humidity control and arousal unit 80, the warm air is discharged outdoors from the humidity control and arousal unit 80 in the Y14 direction, and outside air is appropriately taken in in the Y13 direction.

Since the circulating warm air cleaning room 60 is arranged in the center below the skip floor 41 on the lower floor, return piping 83 extends from the circulating warm air cleaning room 60 located in the center or approximately the center of the building to each room. In addition, the total length of the resupply pipe 84 can be made as short as possible.

In addition, since the return piping 83 and resupply piping 84 extending from the circulation warm air clean room 60 to each room can be installed in the vertical direction in principle, air resistance is reduced by reducing the bending of the piping. This makes it possible to maintain high circulation of warm air for a long period of time.

Furthermore, air conditioning equipment 89 is provided in the circulation warm air clean room 60, and the room temperature of the circulation warm air clean room 60 is set to the same or substantially the same temperature as the set temperature of each room to which warm air is supplied again. , it is possible to reduce the heat load on the heating and cooling equipment in each room.

It should be noted that other embodiments may be adopted in which other components are combined with the configurations listed in the above embodiments, and the present invention is not limited to the configurations shown here. In this regard, changes can be made without departing from the spirit of the present invention, and can be appropriately determined depending on the application form.
