Fresh outdoor air (eg, temperature 31 ° C, O.A 30%) is mixed (27 ° C, O.A 100%) in the mixing unit 18, and passes through the supply air heat exchanger 9 at a temperature and air volume sufficient for indoor cooling (eg, After the temperature is adjusted to 17℃, S.A. 100%), it is supplied to the room through the air supply fan (7), the air supply chamber (1) and the air supply port (1).

In addition, discarded indoor air (e.g., temperature of 25° C., R.A. 30%) passing through the other indoor air inlet 6b cools the compressor 13 while passing through the compression unit 15 and prevents the compressor 13 from overheating. After passing through the outside air inlet (5) (e.g., temperature 31 ° C, air volume E.A. 100%) and mixed again (130%), the exhaust heat exchanger (10), the exhaust fan (8), the exhaust chamber (3), and the exhaust port (4) ) through which it is discharged to the outside.

That is, exhaust waste heat discarded as much as the amount of fresh outdoor air introduced is in the same state as the indoor temperature (25° C.), and is sent to the exhaust heat exchanger 10 for condensation using the waste heat, so that the condensation temperature is lowered and the compressor 13 ) is cooled to prevent overheating.

In addition, since the cooling operation may be stopped while the compressor 13 is stopped due to the high pressure operation according to the outdoor air temperature rise, in the present invention, when the temperature of the exhaust unit 20 is operated above the set value (eg, 45 ° C.), the spraying device The water spray valve 25 is operated to cool the exhaust heat exchanger 10 while cooling water is sprayed, thereby lowering the condensation temperature of the exhaust heat exchanger 10 and increasing the condensation efficiency while preventing overload of the compressor 13, thereby providing stable cooling.

At this time, it is possible to maintain the room temperature of the exhaust unit 20, and only the external ventilation amount is adjusted regardless of the outdoor air temperature, thereby preventing frost that occurs when the outdoor air temperature is low (e.g., 7°C) or lower. Heating operation becomes possible.

The emergency supply air heater 11 generates 20% of the total amount of heat that can be generated by the emergency supply air heater 11 rather than operating the whole, and uses the amount of heat that is bypassed for the remaining amount of heat. As a result, electric energy is greatly reduced and energy efficiency is excellent.
