A cogeneration system including an engine (50), which drives a generator (52) to generate electricity, a cooling/heating unit (60), which comprises at least one compressor (61), a four-way valve (62), an outdoor heat exchanger (63), an expansion device (64), and an indoor heat exchanger (65), to establish a heat pump type refrigerant cycle, and an exhaust heat consuming heating unit (70) to supply heat of exhaust gas discharged from the engine (50) to a heat exchanging zone of the indoor heat exchanger (65) of the cooling/heating unit (60), and thus, to heat a confined space. Since waste heat generated from the engine (50) is directly used in the cooling/heating unit (60), an enhancement in indoor heating efficiency is achieved. |
