(For example, regarding heating and cooling methods, there is a heating and cooling system shown in Air Conditioning and Sanitary Engineering Wire Networks, Inc., "Practical Knowledge of Air Conditioning Equipment" (revised 2nd edition), P. 16B.) Problems The conventional air-conditioning and heating systems described above cannot exhaust contaminated air generated indoors, and it is necessary to provide a separate ventilation system for ventilation. However, simply ventilating the room will not only increase the heating and cooling load, but it will also make people feel uncomfortable because it cannot humidify the room even when it is dry, and electricity usage will also increase. There was the issue of putting it away.

The present invention solves the above-mentioned conventional problems. It enables heating and cooling while discharging contaminated air generated indoors, prevents an increase in the heating and cooling load due to ventilation, and improves indoor temperature and humidity without requiring manual labor. The object of the present invention is to provide a ventilation air conditioning system that can automatically control the air conditioner to a comfortable state and that consumes less electricity.

A control section is provided for controlling the cold/hot water coil and the humidifier based on the signal from the temperature/humidity sensor.

Function When you operate the motor with air supply vanes and exhaust vanes and the ventilation fan motor, if the room is dry but cold or hot, the signal from the temperature and humidity sensor will turn off cold or hot water. The coil and humidifier are operated, and indoor air from each suction port enters from the indoor suction port, and some goes to the exhaust vane.
The remaining waste is then guided through the opening to the fan motor for blowing air.

The air guided by the exhaust vanes passes through the heat exchanger, passes through the outdoor outlet, and is discharged outdoors.At the same time, outside air enters the outdoor air inlet, passes through the supply air vanes, and undergoes heat exchange. After exchanging heat with indoor air in the chamber, it is guided to a blower fan. After mixing with the remaining indoor air that is led directly to the blower fan motor, the air passes through a temperature and humidity sensor, is heated or cooled by a hot and cold water coil, and is humidified by a humidifier to be supplied to each room. Ru. In addition, when the room becomes comfortable, the cold/hot water coil and humidifier are stopped by a signal from the temperature and humidity sensor, and the indoor air from each intake port enters through the indoor intake port, and some of it is exhausted. The remaining air is guided through the opening to the fan motor for blowing air. The air led to the exhaust vanes passes through the heat exchanger, passes through the outdoor outlet, and is discharged outdoors. At the same time, outside air enters the outdoor air inlet, passes through the air supply vanes, and is heated. After exchanging heat with indoor air in the exchanger, it is guided to the fan motor for blowing air.
