ELECTRIC GENERATION AIR CONDITION SYSTEM AND THE CONTROL METHOD FOR THE SAME

摘要

A cogeneration system and a method for controlling the same are provided to maintain the heating efficiency of an air conditioner constantly by supplying the wasted heat of a drive source to the air conditioner. A cogeneration system includes a generator(50), a drive source(52), a wasted heat recovering unit, a wasted heat supplying heat exchanger(80), an air conditioner, and a control unit. The drive source drives the generator. The wasted heat recovering unit recovers the wasted heat of the drive source. The wasted heat recovered by the wasted heat recovering unit is transferred to the wasted heat supplying heat exchanger. The air conditioner includes an outdoor unit and an indoor unit. The outdoor unit includes a compressor, a four-way valve, an outdoor heat exchanger, and an outdoor expansion valve. The indoor unit includes an indoor expansion valve and an indoor heat exchanger. After the refrigerant in the air conditioner is evaporated by the wasted heat of the drive source in the wasted heat supplying heat exchanger, the control unit determines an error according to a suction pressure.
