A cogeneration system including an engine, which drives a generator to generate electricity, a cooling/heating unit, which includes at least one compressor, a four-way valve, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger, to establish a heat pump type refrigerant cycle, and a refrigerant over-heating unit to supply heat of cooling water used to cool the engine to a suction-side refrigerant line of the compressor of the cooling/heating unit, and to supply heat of exhaust gas discharged from the engine to the suction-side refrigerant line of the compressor and to a discharge-side refrigerant line of the compressor. In accordance with the cogeneration system, it is possible to maximize absorption of the waste heat of the engine while preventing compressor malfunction, and thus, to increase the refrigerant condensing temperature of the indoor heat exchanger. Thus, an enhancement in heating performance is achieved.
