A cogeneration system including an engine, which drives a generator to generate electricity, a cooling/heating unit, which comprises 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 an exhaust heat consuming heating unit to supply heat of exhaust gas discharged from the engine to a heat exchanging zone of the indoor heat exchanger of the cooling/heating unit, and thus, to heat a confined space. Since waste heat generated from the engine is directly used in the cooling/heating unit, an enhancement in indoor heating efficiency is achieved.
