Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an air conditioning ventilation system that performs ventilation with heat exchange for an entire building.

[Background Art] In recent years, buildings such as general residences have become more airtight, and it has become difficult to provide natural ventilation through gaps in window frames, doors, walls, ceilings, etc. Therefore, unless buildings are proactively equipped with ventilation equipment, indoor contamination by carbon dioxide, carbon monoxide, dust, cigarette smoke, moisture, etc. in living rooms is likely to progress. Carbon dioxide, carbon monoxide, dust, cigarette smoke, etc. are harmful to health, and moisture causes dew condensation on walls, closets, windows, etc., damaging building structures. Particularly in the winter, people tend to rarely open windows for ventilation, and such problems are particularly likely to occur.

By the way, in modern homes, the LDK (living/dining kitchen) is used as a one-room living room and is heated. I spend most of my waking life in this LDK. Therefore, this LDK can be said to be a source of indoor air pollution in general homes. On the other hand, areas other than the LDK, such as bedrooms and closets, are at low temperatures and are particularly susceptible to condensation when air from the LDK flows in. Also, carbon dioxide, carbon monoxide, dust, cigarette smoke, etc. from the LDK are likely to flow in. Therefore, simply ventilating only the LDK with the outdoors will not maintain a comfortable living environment for the entire building. Also, LDK
If all the bedrooms and closets other than the LDK were heated separately and at the same time, the heating costs would be enormous and it would be inefficient.

[Object of the Invention] An object of the present invention is to provide an air conditioning ventilation system that can maintain a comfortable living environment in the entire building while performing efficient heating.

[Structure of the Invention] Therefore, the present invention allows the exhaust flow from a high-temperature and humid partitioned space such as an LDK to exchange heat with the outside air in a heat exchanger and then to be exhausted outdoors. The heated outside air is once introduced into a low-temperature partitioned space such as a bedroom or closet that is separate from the high-temperature and humid partitioned space such as the LDK, and then,
By introducing air from this low-temperature partitioned space into the high-temperature and humid partitioned space, the temperature of the low-temperature partitioned space is raised and the humidity is lowered to prevent condensation, and the ventilation route throughout the building is clearly defined in this way. The purpose is to achieve the above object by preventing contaminated air from the hot and humid partitioned space from flowing into the cold partitioned space. Note that the partitioned space referred to here is not limited to spaces where people go in and out, such as the kitchen, dining room, living room, living room, bedroom, bathroom, and toilet, but also includes spaces where people do not go in and out, such as closets and attics.

[Description of Embodiment] Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows an entire building such as a general residence to which an embodiment of the air conditioning ventilation equipment according to the present invention is applied, and this building has first, second, third, fourth partition spaces 1, 2, 3, and 4, and a heat exchanger 6 is arranged in the attic 5.

The first partitioned space 1 is a high-temperature and humid partitioned space, such as an LDK, for example, and contains carbon dioxide,
It is a source of pollution such as carbon monoxide, dust, cigarette smoke, and moisture. Further, the second partition space 2 is a low temperature partition space such as a bedroom or a closet adjacent to the first partition space 1, and the third partition space 3 is a low temperature partition space such as a bedroom or a closet.
is a source of pollution such as a toilet or washroom, and the fourth partitioned space 4 is a bathroom or the like.

The exhaust flows of the first and third partition spaces 1 and 3 are introduced into the heat exchanger 6 via the exhaust duct 7,
These exhaust streams undergo heat exchange with the outside air taken in by the heat exchanger 6, and then are exhausted to the outdoors via the exhaust duct 8. On the other hand, the intake outside air is introduced into the heat exchanger 6 via a suction duct 9, and the suction port of this suction duct 9 is arranged inside the attic 5. Also, an attic ventilation opening 11 is provided in the attic 5. It is being The intake outside air warmed in the heat exchanger 6 is once introduced into the second partitioned space 2 via the air supply duct 12, and from this second partitioned space 2 is passed through the vent 13.
The liquid is introduced into the first partitioned space 1 and the third partitioned space 3 through the ventilation holes 14, respectively.

The vent 13 that communicates the first partitioned space 1 and the second partitioned space 2 is equipped with a fan coil type radiator 15, as shown in an enlarged view in FIG. This radiator 15 has a coil 16 to which hot soot such as hot water is circulated and supplied from a heat source such as a boiler.
and a fan 17 arranged on the first partition space 1 side.
The circulating air in the first partitioned space 1 and the second partitioned space 2 are supplied to the coil 16 by the fan 17.
The air introduced from the inside is also introduced and heated, and then blown out into the first partitioned space 1.

This embodiment has the following effects.

The intake outside air with low absolute humidity is warmed in the heat exchanger 6 by the high-temperature exhaust flow from the first partition space 1 and then blown out into the second partition space 2 where condensation is likely to occur. It is possible to raise the room temperature of the space 2 and lower its humidity. Therefore,
It is possible to prevent dew condensation in the second partition space 2, where dew condensation was extremely likely to occur in the past.

In addition, when this second partition space 2 is a closet or the like, the effect of preventing dew condensation is particularly large, and
It is also possible to prevent noise such as the sound of balloons.

Furthermore, ducts 7, 9, 12, vents 13, 1
4. Since the fans 17, etc. are arranged as described above to make the ventilation route for the entire building clear, the hot and humid air in the first partition space 1 does not flow into the second partition space 2, etc. From this point of view, condensation in the second partitioned space 2 can be prevented, and the contaminated air in the first partitioned space 1 will not flow into the second partitioned space 2, etc. From these points, the comfort of the entire building will be improved. A safe living environment can be maintained.

Moreover, instead of heating all of the partitioned spaces 1, 2, 3, and 4 individually and simultaneously, the system maintains a comfortable living environment throughout the building by establishing an unprecedented ventilation route, which reduces heating costs. It requires less and is efficient.

Furthermore, by providing the heat sink 15, the heat sink 1
Since the temperature of the supply air introduced into the first partitioned space 1 through 5 is warmed in advance, there is no discomfort caused by cold draft.

In the above embodiment, the radiator 15 takes in a part of the air in the first partitioned space 1 on its suction side to provide a circulation effect and perform heating and ventilation at the same time. , not limited to this,
For example, like the radiator 25 shown in FIG. 3, it may be only for heating the introduced air introduced from the second partition space 2 into the first partition space 1. However, if you want to perform not only the auxiliary function of heating the first partitioned space 1, but also the entire heating, there is a type that simultaneously performs heating and circulation from an area where the air volume is insufficient. Are suitable. Furthermore, although the radiators 15 and 25 are not necessarily necessary, and the positions of the vents 13 and 14 are not particularly limited, it is said that if they are placed near the ceiling, there will be no discomfort as the introduced air will not be blown directly onto the human body. effective. Furthermore, the suction port of the suction duct 9 is not limited to being placed inside the attic 5;
If it is placed inside the attic 5, it has the effect of preventing dew condensation inside the attic 5. Furthermore, although the partitioned spaces 1 and 2 are adjacent to each other, they may be communicated with each other by a duct or the like, but may not be adjacent to each other.

[Effects of the Invention] As described above, according to the present invention, it is possible to provide an air conditioning ventilation system that can maintain a comfortable living environment in the entire building while performing efficient heating.
