Abstract

A ventilation system includes a refrigerant circuit, supply and exhaust fans, and a control unit. The refrigerant circuit has a compressor and first and second heat exchangers connected by a refrigerant pipe with a refrigerant flowing in the refrigerant circuit. The supply fan is arranged to supply air from an outdoor space to an indoor space through the first heat exchanger. The exhaust fan is arranged to exhaust air in the indoor space to the outdoor space through the second heat exchanger. The control unit determines whether the supply fan and the exhaust fan are normal. The control unit, upon determining that one of the supply fan or the exhaust fan is abnormal, stops the one of the supply fan or the exhaust fan determined to be abnormal, and continues an operation of an other one of the supply fan or the exhaust fan determined to be normal.
