Specification

Heat exchange ventilation system

The present invention relates to a ventilation air conditioning unit that recovers heat while ventilating a closed living space with closed windows. Background art

Conventionally, ventilation was performed as follows in a closed living space where the installation space was limited and the windows were completely closed in summer and winter. An example of installing an outdoor air supply duct and an outdoor exhaust duct from a heat exchange ventilation device (hereinafter referred to as a ventilator) near the looper in a partitioned indoor space to ventilate the room in an open state. Are known.

In this case, the louver has a lattice or a slit opened to the outdoor space. And they are fixed to the frame. A conventional ventilation system will be described with reference to FIGS. 18 and 19. As shown in Fig. 18, in the indoor space 102 and the outdoor space 103 separated from the living space 101, the ventilation device 104 is provided in the partitioned indoor space 102. As shown in Fig. 19, the ventilator 104 has an indoor suction duct 1105 with an indoor suction port 116 on the side and an outdoor with an outdoor discharge port 118 on the side. The discharge duct adapter 106 is provided.

Further, an exhaust blower 107 for blowing air to an exhaust air passage extending from the indoor suction duct adapter 105 to the outdoor discharge duct adapter 106 is provided. In addition, the ventilation system 104 is on the side, It has an outdoor suction duct adapter 108 having a suction port 117 and an indoor discharge duct adapter 109 having a indoor discharge port 115. An air supply blower 110 is provided for blowing air into the air supply path from the outdoor suction duct adapter 108 to the indoor discharge duct adapter 109. Further, the ventilator 104 has a heat exchange element 111 at the intersection of the exhaust air path and the supply air path.

An example of such a heat exchange element 111 is disclosed in Japanese Patent Application Laid-Open No. H8-73585.

In addition, known heat exchange elements can be used. The ventilator 104 is fixed to the ceiling surface by the suspended port 112.

Partition 1 between outdoor space 1 03 and indoor space 1 0 2

1 3 is provided with a lever 1 1 4. The living space 101 is provided with an indoor outlet port 115 and an indoor inlet port 116.

In addition, the outdoor suction port 1 17 and the outdoor discharge port 1 18 are installed in the vicinity of the valve 1 14 in an open state. An exhaust air path and an air supply air path from the outdoor space 103 to the ventilation device 104 will be provided. Further, the inside discharge duct adapter 109 and the inside discharge port 115 are connected by a duct. In this way, the air in the outdoor space 103 can be taken into the room. In addition, a duct-type connection is made between the indoor suction / discharge duct adapter 105 and the indoor suction port 116.

Thus, the air in the living space 101 can be exhausted to the outdoor space 103. The above is the conventional ventilation system.

In such a conventional ventilation system, since outside air is taken in from the partitioned indoor space 102, outdoor exhaust air is supplied to the room again. In other words, we can take in fresh air efficiently There is a problem that there is no.

Also, when high humidity air inside the room is exhausted from the louver in winter, it is cooled by the outdoor low temperature air and becomes saturated, and water drops are formed on the louver part. Eventually, icicles are formed and issues such as falling icicles occur.

Also, in winter, there is a problem that condensation occurs in the ventilation system depending on the outside air temperature, and condensed water drops.

Another problem is that insects can enter the room through the air supply duct. Furthermore, in an environment where strong outside wind is generated, there is a problem that outside air blows into the room even when the main unit is stopped.

The present invention solves such a conventional problem, and provides a heat exchange ventilation system capable of recovering heat while performing ventilation in a closed space with closed windows. DISCLOSURE OF THE INVENTION ''

Then, the indoor discharge duct adapter 19 provided in the ventilator 4 and the indoor discharge port 21 provided in the living space 1 are connected by a duct. Thus, the air in the outdoor space 3 can be taken into the room. On the other hand, a duct connects the indoor suction duct adapter 5 provided in the ventilator 4 to the indoor suction port 20 provided in the living space 1. Thus, the air in the living space 1 can be exhausted to the outdoor space 3.

When the ventilator 4 and the chamber part 26 are integrated as in the above configuration, the installation space in the partitioned indoor space 1 can be reduced. As a result, duct piping for connecting the chamber part 26 and the ventilation device 4 is not required, and a heat exchange ventilation system can be constructed at low cost.

Then, heating means A 28 is placed on the flat surface where the outdoor air touches looper 27. Prepare. A heating wire such as a nichrome wire is used as the heating means A. Conventionally, in the winter, high humidity air in the room is exhausted, cooled by the low temperature air outside and becomes oversaturated, and water droplets are formed on the looper part, and the water droplets may become icicles and fall. On the other hand, according to the above configuration, it is possible to provide a heat exchange ventilation system that can prevent icicles from occurring by warming the louver 27.

(Embodiment 5)

As shown in Fig. 11 and Fig. 12, the heating means B is provided in the partial air supply passage 15 of the chamber 19 in the chamber 19 installed in the partition section 13.

2 9 is provided.

The outdoor air supply air is supplied to the chamber air supply passage equipped with heating means B29.

It is sucked into ventilator 4 through 1 5. A heater using dichrome wire or hot water is used as the heating means B29.

With the above configuration, the replacement due to the decrease in the outside air temperature in winter

It can be warmed up until it is sucked in 4 ■ ό.

By reducing the temperature difference between the suction air and the room air in the manner described above, it is possible to prevent the occurrence of dew condensation on the ventilation device 4 or the duct.

(Embodiment 6)

As shown in FIG. 13, the partial chamber air supply passage 15 between the outdoor space 3 and the chamber-side suction port 17 in the chamber 19 is provided between the outdoor space 3 and the chamber-side discharge port 18. A wind direction plate 30 is provided for each of the partial exhaust wind paths 14 and the chamber.

The installation location of the wind direction plate 30 is as follows: only the air supply passage 15 in the chamber, only the exhaust air passage 14 in the chamber, and the air supply For example, there is a case where both the passage 15 and the chamber partial exhaust air passage 14 are provided. The location of the wind direction plate 30 may be any of these.

With the configuration described above, the wind directions of the outdoor exhaust air and the outdoor supply air can be changed, and the outdoor exhaust air can be prevented from being sucked into the room again.
