Description

  The present invention relates to a technique for reducing the consumption of fossil fuel in a detached house, particularly a detached house in a cold region.

  In a detached house in a cold region, the indoor temperature is kept comfortable by operating heating devices such as various kerosene stoves arranged indoors in severe cold seasons. Further, in the Hokkaido eastern region and the like, a heating device may be required not only in the severe winter period but also in early spring and summer.

  In a detached house in such a cold area, when a heating device such as a kerosene stove is operated, the room temperature is kept comfortable, but the fuel cost (kerosene expense) increases, so the economic burden increases. There's a problem.

  For this reason, conventionally, the proposal which raises the heating efficiency especially in winter has been made. For example, the indoor wall of a detached house is made into a double structure, and warm indoor air is circulated (patent document 1).

  If the outer wall of a detached house has a double structure and warm indoor air is circulated in the internal space, the heating efficiency is reliably improved. Moreover, if the air which flowed the outer wall space of the double structure is sent under the floor and the underfloor space (the basic space of the house) is always warmed, the heating efficiency is further improved (Patent Document 1).

  A similar outer wall structure is also disclosed in Patent Document 2. This Patent Document 2 discloses that an air flow that causes an outer wall to flow is also sent to a ceiling space and a shed space. This is to warm the ceiling space and the attic space to prevent the temperature of the living room from being lowered as much as possible and to increase the heating efficiency.

JP 2014-051874 A JP-A-2004-060959

  The problem is that in order to circulate the air flow with the outer wall having a double structure, not only the construction cost is increased, but also the construction period is extended. This is because not only the outer wall structure of a detached house becomes complicated, but also derivative construction problems such as the installation of openings for securing the flow of indoor air and the installation of dustproof equipment accompanying the installation of openings arise.

  In addition, it is not technically difficult to flow indoor heating air into the double outer wall space or send it to the floor, ceiling, or shed, but it is technically difficult, but the living room space and the outer wall, under the floor, ceiling, hut Spatial communication between the back and the like is not preferable from a hygienic viewpoint.

  Furthermore, although it is possible to construct a double-structured outer wall from the design stage in a new house, it is difficult to quickly apply it to existing houses, and large-scale construction is required even if renovation is performed.

  Moreover, the conventional proposal presupposes using heating apparatuses, such as a stove. However, there is a problem peculiar to the cold region that if the heating device is operated even at low temperatures in early spring, summer, and autumn, the total amount of fossil fuel costs increases throughout the year.

  Therefore, an object of the present invention is to make it possible to save fossil fuel by improving the heating efficiency of a detached house in a cold region without sanitizing the double structure of the outer wall.

  In order to achieve the above object, an auxiliary heating system for a detached house according to the present invention is provided with a sunlight collecting chamber using a transparent plate on the outside of the outer wall of the detached house, and a heat pump device (air) in the detached house. A solar heat collecting chamber is provided outside the outer wall in the direction of receiving sunlight among the outer walls, and the heat pump device is provided with a heat exchanger in the sunlight collecting chamber or the housing basic space. On the other hand, the radiator was installed in the housing basic space, and the air flow sent from the heat exchanger was returned to the heat exchanger after passing through the sunlight collecting chamber, and was discharged from the radiator The air flow that stores the heat radiation air in the concrete of the house foundation and circulates it through the positive heat collecting chamber is sent to the vicinity of the intake portion of the heat exchanger via the duct (Claim 1).

  The auxiliary heating system for a detached house according to the present invention does not flow indoor heating air, but uses exhaust air from a heat pump device installed in an appropriate place (a solar heat collecting room or a housing basic space) other than the living room. Then, the air in the sunlight collecting chamber provided outside the outer wall is circulated and flowed. The temperature of the air in the sunlight collecting room rises when it is illuminated by the sun (during sunny daylight). Since the air in the high temperature sunlight collecting chamber flows and circulates / circulates to the heat exchanger of the heat pump device, the radiator installed in the housing basic space quickly rises in temperature, so a little electricity to operate the heat exchanger Can gain a large amount of heat energy and warm the floor.

  In this way, it is possible to keep the room at a comfortable temperature without operating the room heating device during the daytime to sunset in the early spring, summer, and autumn seasons. Even if it is lowered, it becomes possible to keep the room at a comfortable temperature, so that the consumption of fossil fuel throughout the year can be greatly reduced.

  Moreover, since it is the circulation of the heat storage air heated by sunlight, and it is an air flow on the conditions spatially separated from the living room, it does not adversely affect the hygiene of the indoor air. Furthermore, since the auxiliary heating system according to the present invention installs the heat pump device radiator in the housing basic space and stores the radiated air in the housing basic space, it also uses the heat storage energy under the floor and uses fossil fuel. Consumption reduction can be made efficient.

  The sunlight collecting chamber may be configured by mounting a colorless and transparent glass plate material on frame means using vertical and horizontal members made of aluminum (claim 2).

  By constructing the sunlight collecting chamber using a colorless and transparent glass plate, the sunlight collecting chamber can accumulate solar heat and maintain a relatively high temperature for a while after sunset from the daytime. In this case, the construction cost for the increase can be suppressed relatively inexpensively by forming a positive heat collecting chamber by attaching a colorless and transparent glass plate material to a frame using vertical / horizontal members made of aluminum. In addition, the heat storage effect of sunlight is maximized.

  Since a colorless and transparent glass plate material is used, it is desirable to use a metal outer wall material for the outer wall into which sunlight is directly inserted. The outer wall material (for example, aluminum decorative material) with good thermal conductivity can be used to efficiently increase the air temperature in the sunlight collecting chamber by utilizing the thermal energy of sunlight.

  A plurality of heat radiators of the heat pump device are arranged at equal intervals in the concrete molded housing foundation space, while the floor under the first floor is molded with slab concrete, and the heat radiated to the housing foundation space through the radiator is In some cases, heat is stored in the concrete of the foundation and the slab concrete under the first floor (Claim 3).

  The number of radiators used in one heat pump device may be at least one. However, when uniformly warming the housing basic space (under the floor of the house), it is more advantageous to arrange a plurality of radiators at even intervals in order to reduce the temperature variation and to keep the heating of the interior space comfortable. .

  If the heat energy released from the radiator is stored in the concrete of the foundation of the house and the slab concrete under the first floor, for example, by starting the heat storage before the start of winter, late autumn-early winter-severe winter- In late winter, you can get warm heat energy from under the floor. For this reason, even if the operating power of the heating device is lowered than before, the room temperature can be kept comfortable, and fossil fuel can be reliably saved.

  According to the auxiliary heating system for a detached house according to the present invention, even if the outer wall is not a double structure, the heating efficiency of the detached house in a cold region can be improved hygienically and fossil fuel can be saved. Will be able to.

It is a figure which shows an example of the auxiliary heating system of the detached house which concerns on embodiment. It is the figure which illustrated the sunlight heat collecting chamber shown in FIG. 1 from a different angle. It is the figure which illustrated the flow of the heat of the auxiliary heating system shown in FIG. It is a figure which illustrates the auxiliary heating system which concerns on other embodiment. It is a figure which shows the specific example of the partition plate which concerns on embodiment. It is a figure which shows the other example of the partition plate which concerns on embodiment. It is a cross-sectional equivalent view of the TT line of FIG.

  FIG. 1 illustrates an embodiment of an auxiliary heating system for a detached house according to the present invention.

  The auxiliary heating device is provided with a sunlight collecting chamber 20 using a transparent plate material on the outside of the outer wall 11 of the detached house 10, and a heat pump device provided with a heat exchanger 31 and a radiator 32 in the detached house 10. Provide. 14 is a concrete foundation of the detached house 10, and 14-2 is a foundation space (a space inside the foundation; an underfloor space). 27 is a partition plate and 38 is a duct. Moreover, the code | symbol Q is the circulation path (pipe material) of the heat medium which connects the heat exchanger 31 and the heat radiator 32, R is the slab concrete of a 1st floor. The duct 38 is desirably provided with a dedicated duct having a large cross-sectional area in order to ensure sufficient air fluidity.

  The positive heat collecting chamber 20 is provided on the outer side of the outer wall 11 that receives sunlight, for example, of the outer wall 11 having a planar rectangle. It is not necessary to provide all the outer walls 11. In this embodiment, the case where the sunlight collecting chamber 20 (20-1, 20-2) is provided in the two outer walls 11 is shown.

  The solar heat collecting chamber 20 is preferably constructed to warm the air with sunlight as much as possible, and is constructed using, for example, a colorless and transparent glass plate material. The glass plate material is appropriately loaded into a frame that is a combination of a vertical material (not shown) and a horizontal material (not shown).

  As the vertical member and the horizontal member used for the frame, for example, various well-known frame members for mounting glass made of aluminum can be used. The area ratio of the colorless and transparent glass plate material is set to be as large as possible within a range that is not unreasonable in structure, and the internal air temperature is raised by receiving more sunlight in the sunlight collecting chamber 20. Structurally, for example, it may be substantially the same as a windbreak room provided outside the entrance of a cold district house. However, the open / close door provided in the air removal chamber is not necessarily provided.

  As shown in FIG. 2, the solar heat collecting chamber 20 includes a glass surface G substantially parallel to the outer wall 11. The distance between the glass surface G and the surface of the outer wall 11 may be set to a size that allows the air flow to freely flow, for example, about 40 to 50 cm. A portion indicated by a symbol P is a space through which an air flow flows. Reference numeral 14-3 denotes a spring foundation for erecting the vertical member of the sunlight collecting chamber 20. The protruding foundation 14-3 is appropriately designed to have a protruding dimension according to the set amount of the separation dimension between the glass surface G and the outer wall 11 surface.

  In addition, when the window W is located in the sunlight collecting chamber 20, it is desirable that the window W has a bay window structure and the opening / closing surface W1 is substantially flush with the glass surface G, for example. This is because the opening / closing surface W1 can be opened to the outside air.

  Returning to FIG. 1, the partition plate 27 includes, for example, an opening F on the downstream side of the air flow, and the air flow A <b> 1 (see FIG. 3) passing below the window W flows above the window W and flows into the heat exchanger 31. It is desirable to return in the direction. The partition plate 27 is made of an appropriate material such as a resin plate, a metal plate, or a wooden plate. The partition plate 27 may be provided with a small hole (not shown) for allowing the air flow A1 to escape upward at an appropriate location. The partition plate 27 is not limited to the lower side of the window W, and may be arranged at the upper position.

  The heat exchanger 31 of the heat pump device is installed in either the sunlight collecting chamber 20 or the basic space 14-2 of the house (10). In this embodiment, the case where the heat exchanger 31 is installed in one (20-1) of the two sunlight heat collection chambers 20 was illustrated. The drive power for the heat exchanger 31 is preferably supplied via a solar panel (solar power generation device; not shown). This is because the solar panel can provide sufficient power to drive the heat pump device (31) in an area where stable sunshine hours are obtained throughout the year, such as Hokkaido's Eastern Hokkaido area. The solar panel is arranged at an appropriate place such as a roof.

  The radiator 32 is installed in the basic space 14-2. Preferably, a plurality of them are arranged at equal intervals in the foundation space 14-2 of a concrete-molded house. This is because the exhaust heat discharged from the radiator 32 is evenly discharged into the foundation space 14-2 so that the concrete foundation 14 (solid foundation) and the slab concrete R can store heat evenly.

  Since the heat exchanger 31 and the radiator 32 can communicate with each other via the circulation path Q, the heat exchanger 31 can be arranged at an appropriate position of the detached house 10, but the heat exchanger 31 according to the present invention takes in the air to be taken in A higher temperature is desired. For this reason, the heat exchanger 31 is not arranged in the state of being exposed to the outdoors, but is installed in either the inside of the sunlight collecting chamber 20 or the basic space 14-2, and the air fed into the heat exchanger 31 The heat collection chamber 20 is circulated and then supplied directly to the intake portion via the duct 38. Note that the air intake port of the duct 38 is preferably opened as high as possible in the sunlight heat collecting chamber 20. This is for taking in warmer air.

  FIG. 3 shows the air flow A <b> 1 exhausted from the heat exchanger 31 and the exhaust heat A <b> 2 exhausted from the radiator 32. The exhaust heat A2 discharged from the radiator 32 is stored in the concrete foundation 14 and the slab concrete R, and the room on the first floor is always warmed from under the floor. In an area where heating is necessary even in early spring, summer, and autumn, the room can be kept at a comfortable temperature due to the presence of warm air in the sunlight collecting room 20 and the heat storage heating effect received from under the floor. This eliminates the need for stove operation in seasons other than winter, as in the prior art, and can greatly reduce fossil fuel consumption.

  The air flow A1 discharged from the heat exchanger 31 disposed in one (20-1) of the sunlight collecting chamber 20 is an appropriate ventilation means D, for example, an opening that spatially communicates the two sunlight collecting chambers 20 or It feeds into the other sunlight collecting chamber 20 (20-2) through the ventilation duct. At this time, the part into which the air flow A1 is first fed is a space below the partition plate 27, and flows through the lower region of the window W downstream, and then flows upward from the downstream opening F to the partition plate 27. The lower region of the window W is caused to flow in the upstream direction. This is because the air temperature in the sunlight collecting chamber 20 (20-2) is higher at the top, so that the air flow A <b> 1 is sent from below and the high temperature air is refluxed to the heat exchanger 31. The air flow A1 is recirculated to the positive heat collecting chamber 20 (20-1) via an appropriate ventilation means D, and sent to the vicinity of the intake portion (back surface or side surface) of the heat exchanger 31 via the duct 38. It is desirable to isolate the intake section and the air supply section (front fan side) of the heat exchanger 31 using a partition plate or the like. This is to prevent the warm air sent to the intake section through the duct 38 from being mixed with the air sent from the air supply section. This makes it possible to reliably send warm air that has passed through the solar heat collecting chamber 20 into the intake portion of the heat exchanger 31.

  On the other hand, the heat medium of the heat exchanger 31 is sent to the radiator 32 via an appropriate circulation path Q such as a pipe. The heat energy of the heat medium is released as exhaust heat A2 through the plurality of radiators 32, and is stored in the concrete of the foundation space 14-2 (concrete foundation 14, slab concrete R under the first floor). As already described, the intake air of the heat exchanger 31 is warm air that has passed through the solar heat collecting chamber 20. For this reason, the temperature of the radiator 32 is reliably increased. According to the experiment, when the warm air that has passed through the sunlight collecting chamber 20 is sent to the vicinity of the intake portion of the heat exchanger 31 and the intake portion and the air supply portion of the heat exchanger 31 are separated by a partition plate or the like, the radiator 32 The temperature was 40-55 ° C. With a small amount of electric power that drives the heat exchanger 31, the underfloor can be effectively warmed.

  Therefore, according to this configuration, sunlight is used to warm the internal air of the sunlight collecting chamber 20 (20-1, 20-2), and the air heated by natural energy (sunshine) is discharged from the heat exchanger 31. The temperature of the radiator 32 can be maintained high by causing the air flow A1 to flow and circulating to the heat exchanger 31. In this way, the housing basic space can be kept at a high temperature with a small amount of electric power, so that the air temperature in the room can be kept relatively high even in the severe winter season, and the amount of fossil fuel used to operate the stove in the room can be reduced. It can be greatly reduced. A comfortable temperature can be obtained without operating the stove in the living room in the season when the outside temperature is not below freezing but it is chilly, such as early autumn and early spring. If the heat exchanger 31 is driven by a solar panel device, the entire power supply can be provided without the need for fossil fuel.

  In the case of a detached house 10 that is not made of concrete, if the heater is turned off and the user goes out in a cold region, the room temperature drops significantly in the severe winter season, and the room air rises to a comfortable temperature even if the heater is turned on after returning home. Although there was a problem that it takes time to do so, it can prevent an extreme temperature drop by receiving heat from the outside of the outer wall 11 or under the floor, so that the room temperature can be quickly raised if the heating device is turned on even in the severe winter season. Will be able to.

  Even in the severe winter season, the temperature of the first-floor room is less likely to decrease, so that the comfort of the room temperature can be maintained even if the operating power of the heating device is reduced. For this reason, it becomes possible to reduce the amount of fuel used for the heating apparatus using fossil fuel, and to greatly reduce the economic burden in winter.

  Although the solar heat collecting chamber 20 has been described to maintain a warm temperature using solar heat, the outer wall 11 is not directly exposed to the outside air even at night when sunlight cannot be used. There is an effect to prevent. In addition, it is desirable not to drive the heat pump device during a time zone (nighttime) other than the sunshine time zone. This is because sunlight cannot be used effectively and heat cannot be stored in the foundation space.

  Unlike the conventional outer wall heating structure in which the outer wall 11 has a double structure, since the solar heat collecting chamber 20 is provided outside the outer wall 11, the indoor air does not mix with the air flow A1. Accordingly, there is no hygienic problem caused by flowing air.

  The auxiliary heating system according to the present invention is not limited to the configuration described above. For example, in the above description, the positive heat collection chamber 20 (20-1) in which the heat exchanger 31 is arranged and the positive heat collection chamber 20 (20-2) provided outside the outer wall 11 with the window W are provided separately. Although it has been described that the air flow A1 circulates between the two, as shown in FIG. 4, another sunlight collecting chamber 20 (20-3) may be additionally provided at an appropriate location in the direction of receiving sunlight. The additional solar heat collecting chamber 20 (20-3) is provided as high as possible. This is because warm air moves up.

  Even when a heat pump device for supplying hot water is used in combination, a heat exchanger (not shown) of the heat pump device is installed in the sunlight collecting chamber 20 (20-1), and a radiator (not shown) is installed in the basic space 14-. 2 can be installed. In this case, it is desirable to isolate the heat exchanger and the heat sink through a partition wall such as a concrete wall. This is to prevent mixing of heat energy between the heat exchanger and the radiator.

  The solar heat collecting chamber 20 (20-1) in which the heat exchanger 31 is arranged is preferably installed toward the southwest direction in order to efficiently use sunlight and the outside air temperature. Even if it receives sunlight, if the outside air temperature is low as in the morning, the internal temperature of the sunlight collecting chamber 20 (20-1) is difficult to rise, so the southwest direction that receives sunlight in the afternoon time zone when the outside air temperature rises It is because the effect which warms the internal air of the sunlight collecting chamber 20 (20-1) can be heightened by providing the sunlight collecting chamber 20 (20-1) toward.

  As shown in FIG. 5, when the heat exchanger 31 of the heat pump device according to the present invention is disposed on the ground floor, it is desirable to provide partition plates 50 and 51. The partition plate 50 is for preventing the temperature drop of the air supply of the heat exchanger 31, and has a function of guiding the air supply of the heat exchanger 31 to the sunlight collecting chamber 20 (20-2) so as not to be mixed with the surrounding air. Run. For example, the partition plate 50 is disposed in parallel with the floor surface at substantially the same height as the upper surface of the heat exchanger 31. Instead of the partition plate 50, a duct that can guarantee a sufficient air flow rate may be used.

  The partition plate 51 is for preventing the circulating air that is returned to the intake portion of the heat exchanger 31 through the duct 38 from being mixed with the air supply of the heat exchanger 31, and the rear surface of the heat exchanger 31 in which the intake port is installed. -Separate the side from the front, which is the air supply port. In this way, the air supplied from the heat exchanger 31 is repeatedly circulated without mixing with the surrounding air and lowering the temperature, so there is no loss of heat energy.

  When the heat exchanger 31 of the heat pump device according to the present invention is arranged under the floor, as shown in FIGS. 6 and 7, the heat exchanger 31 is placed on the duct 38 side of the basic space 14-2, and the first floor slab is placed. The function of the partition plate (50) is given to the concrete R. Also in this case, a partition plate 51 is provided so that the circulating air returned to the intake portion of the heat exchanger 31 through the duct 38 is not mixed with the air supplied from the heat exchanger 31. In FIG. 6, reference numeral 54 denotes a fabric foundation. As shown in FIG. 6, the heat exchanger 31 and the radiator 32 are isolated using a cloth foundation 54 and a partition plate 51 to avoid heat mixing.

  In the case where the heat exchanger 31 is arranged under the floor (foundation space 14-2), for example, from the end opening on the opposite side of the slab concrete R on the first floor, the positive heat collection on the jumping foundation 14-3 Air supply (A1) is sent into the chamber 20 (20-2) (see FIG. 7).

  Further, the air flow A1 passing through the sunlight collecting chamber 20 (20-2) is more preferably allowed to pass through the sunlight collecting chamber 20 (20-4) provided on the inner roof 55 through the duct 38. Return to the intake section of the heat exchanger 31. The sunlight collecting chamber 20 (20-4) is constructed by arranging, for example, a glass plate G having an appropriate inclination angle on the inner roof 55. If the inclination angle is increased, the internal volume can be increased, and the amount of air warmed by sunlight can be increased.
