Abstract

A cogeneration system is disclosed. The cogeneration system includes a heat pump type air conditioner, a waste heat recoverer to recover waste heat of a drive source, a waste heat supplying heat exchanger, which is heated by the waste heat recovered by the waste heat recoverer, and a bypassing unit, which causes the waste heat supplying heat exchanger to function as an evaporator during a heating operation of the heat pump type air conditioner. In accordance with this arrangement, it is possible to enhance the heating capacity of the heat pump type air conditioner irrespective of outdoor temperature, to prevent damage of compressors, and to minimize power consumption.
