Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air conditioner for heating, cooling, and ventilating a building, or for heating, cooling, and air purification.

2. Description of the Related Art The conventional method of heating and cooling is to install an air conditioner 101 with a motor 104, a fan 105, and a cold/hot water coil 106 as shown in FIG. Hot or cold air is sent through the air supply duct 102, and ventilation is returned to the air conditioner 101 through the ventilation duct 1o3. The air returned to the air conditioner 101 is accelerated by a fan 106 driven by a motor 104, heated or cooled by a cold/hot water coil 106, and then passed through the air supply duct 1o2 again to be sent to each room.

(For example, regarding heating and cooling methods, please refer to the ``Practical Knowledge of Air Conditioning Equipment'' (revised 2nd edition)
(Edition) Page 168) Problems to be Solved by the Invention The conventional heating and cooling methods described above do not have ventilation or air purification functions, so they cannot exhaust contaminated air, take in fresh outside air, or remove pollutants. - Contaminated air such as combustion waste gas generated in the room and pollutants such as cigarette odor and smoke were diffused throughout the room, causing discomfort. In addition, the smell of cigarettes and the like seeped into the air supply duct 102, and the discomfort increased as time passed. Therefore, it was necessary to incorporate ventilation and air purification equipment. However, if ventilation is simply performed, even if heat exchange ventilation is performed, there will be heat loss, leading to an increase in the heating and cooling load. In addition, if you simply incorporate an air purification device, wind will continue to flow through the air purification section, which will require more frequent maintenance of the air purification device, which not only takes time and effort, but also shortens the life of the air purification device. had the following issues.

The present invention solves the above-mentioned conventional problems, and provides constant ventilation while suppressing the increase in heating and cooling load due to ventilation.
Indoor ventilation can be changed at any time depending on the contamination situation and returned to the room after purification. This prevents contaminated air and pollutants generated indoors from spreading to each room, and also To provide a ventilation air conditioner that prevents odor from penetrating into the air supply duct of a vehicle, requires less frequent maintenance of the air purifier, and can purify the air without shortening its life.

Means for Solving the Problems In order to achieve the above object, the ventilation air conditioning system of the present invention has the following features:

An air purification device and a damper are built into the diverted air passage,
The configuration is such that it is possible to switch whether or not to purify the indoor ventilation that has been diverted to the heating and cooling section before introducing it.

Function: With this configuration, the indoor ventilation introduced into the divided air passage section is divided into the heating/cooling section and the ventilation section.

The indoor ventilation introduced into the ventilation section is pressurized by the exhaust fan of the ventilation fan motor, and is discharged outdoors through the total heat exchanger. At the same time, outside air is sucked in by the air supply fan of the ventilation fan motor, exchanges heat with indoor ventilation in the total heat exchanger, and then is led to the ventilation fan in the heating and cooling section. 3 On the other hand, indoor ventilation led directly to the heating and cooling section is
If the indoor ventilation is clean, if you close the air purification device with a damper and leave the bypass passage open, the air will be guided directly to the blower fan, mixed with the outside air, and then heated or cooled by the coil. It is supplied to each room and performs heating or cooling and constant ventilation. In addition, if the indoor ventilation is dirty, by opening the air purification device with a damper and closing the bypass passage, the indoor ventilation will pass through the air purification device, and after being purified, it will be guided to the blower fan. After mixing with the outside air, it is heated or cooled by a coil, and then supplied to each room for heating or cooling, constant ventilation, and air purification.
