Description

  The present invention provides an air heat exchanger that is provided with a living room and a corridor adjacent to the living room, and that performs heat exchange between supply air and exhaust air accompanying ventilation while ventilating the living room. It relates to the buildings that have been established.

Conventionally, in this type of building, as shown in FIG. 3, the room temperature can be maintained while the inside of the living room 1 is ventilated by the total heat exchanger 4 installed as the air heat exchanger. Generally, it is configured.
That is, in the total heat exchanger 4, an intake passage 5 for taking in building outside air (hereinafter simply referred to as outside air), an exhaust passage 6 for discharging indoor air (hereinafter simply referred to as inside air), and both passages And a heat exchanging part 7 for exchanging heat between the circulating air of each other, the start end of the intake passage 5 being an air intake part 5a opened to the outside, and the end part being an air supply part opened to the room On the other hand, the exhaust flow path 6 has a start end portion that is open to the indoors, a return air portion 6a that is opened indoors, and a terminal portion that is an outdoor air outlet that is open to the outside (hereinafter simply referred to as an exhaust portion). 6b is connected in communication.
In this way, conventionally, the air intakes and the air outlets are arranged on the premise of ventilation between one living room 1 space and the building exterior space.
However, in the heat exchange between the intake and exhaust by the total heat exchanger 4, it is very difficult to completely recover the heat, so in reality, the air exhausted from the exhaust passage 6 to the outside of the building. Is a state in which some temperature difference from the outside air remains, and the heat (hot and cold) of this temperature difference was not utilized.
In view of this, a technology has been born that makes it possible to save energy by effectively using the heat of the air exhausted while leaving a temperature difference from the outside air (see, for example, Patent Document 1).
In this technique, as shown in FIG. 4, the end portion of the exhaust passage 6 is not opened to the outside of the building, but by providing a long duct D, a toilet 2 provided at a position away from the living room 1. The exhaust passage 6 is extended to the toilet 2 and the exhaust portion 6b is opened toward the toilet 2. And the air in the toilet 2 is exhausted outside the building by the ventilation fan 8a provided in the toilet 2.
Accordingly, the air in the exhaust passage 6 exchanged by the total heat exchanger 4 is exhausted from the duct D through the toilet 2 to the outside of the building, and the temperature of the outside air in the toilet 2 space. The heat of the exhausted air can be transmitted with the difference left, and the temperature environment in the toilet 2 can be brought closer to the temperature environment in the living room 1 without installing a special air conditioner in the toilet. It becomes.

Japanese Patent Laid-Open No. 11-325536 (FIG. 1)

According to the conventional building described above, the positional relationship between the living room and the toilet is not necessarily close, but rather, the water space in the building and the living room space are often separated from each other. From the total heat exchanger to the exhaust part provided in the toilet, the duct length tends to be long, and the material cost and the construction cost increase. There is a problem that the resistance increases, the blower such as a fan becomes larger, and the equipment cost is likely to increase.
Moreover, the use of the heat of the air exhausted from the living room space while leaving a temperature difference from the outside air is limited to the toilet space, and there is a problem that the energy saving effect does not reach a wider range of the building.

In a building provided with an air heat exchanger, an air outlet that allows the air in the hallway to be exhausted to the outside of the building is provided, and an air outlet for indoor air in an exhaust passage of the air heat exchanger is opened in the hallway. It is in the place that is in the state to do.

According to the first characteristic configuration of the present invention, since the indoor air outlet is provided for the corridor located very close to the living room, the duct from the air heat exchanger to the indoor air outlet is provided. However, it is possible to secure the exhaust flow path without making it long as in the past, and to reduce the material cost and the construction cost. This makes it possible to reduce the cost of the entire building including the reduction of the cost.
In addition, considering that corridors themselves are often formed in communication with all other indoor parts such as other living rooms, toilets, and kitchens, the temperature difference between the living room space and the outside air remains. The use of the heat of the air exhausted in the state is not limited to the toilet space as in the prior art, but can be effectively used in a wide range in the building leading to the corridor.
Therefore, for example, even when only the living room is in the cooling operation, the cold heat can be received in a wide range in the building through the corridor, and it is possible to stay relatively cool outside the living room.
In other words, the habitability in a wider area in the building can be improved without incurring little initial cost or running cost, thereby contributing to energy saving.

  According to a second characteristic configuration of the present invention, the exhaust port is disposed at a position higher than the indoor air outlet.

According to the second characteristic configuration of the present invention, in addition to being able to achieve the above-described operational effects according to the first characteristic configuration of the present invention, the building of air blown out from the indoor air outlet to the hallway The discharge to the outside can be promoted by utilizing the effect of the rising airflow generated by the temperature difference of the air.
Therefore, it is possible to achieve natural exhaust without providing a special exhaust device that exhausts the corridor air to the outside of the building, and even if an exhaust device such as a fan is provided, the power can be reduced. It becomes possible to achieve energy saving.

  According to a third characteristic configuration of the present invention, the building body has a plurality of levels, the staircase is provided in a state communicating with the corridor, and the exhaust port is disposed on an upper end side of the staircase. There is.

According to the third characteristic configuration of the present invention, in addition to being able to achieve the above-described operational effect according to the first or second characteristic configuration of the present invention, the air blown out from the indoor air outlet to the hallway It is possible to further promote the discharge of the air to the outside of the building by utilizing the action of the updraft caused by the temperature difference of the air.
That is, the air blown out from the indoor air outlet to the corridor is exhausted from the exhaust port to the outside of the building through the staircase, but by making full use of the height difference of the staircase. A chimney effect can also be expected, and natural exhaust can be achieved without providing a special exhaust device. Even when an exhaust device such as a fan is provided, it is possible to reduce the power of the exhaust device and to promote further energy saving.
