Abstract
A cogeneration system is disclosed which includes a waste heat recovering heat exchanger for recovering waste heat generated from a drive source when the drive source operates to drive a generator, heating heat exchangers for heating indoor air, and a heat transfer unit for transferring heat from the waste heat recovering heat exchanger to the heating heat exchangers. The waste heat of the drive source can be used to heat indoor air present in an indoor space. Accordingly, it is possible to maximize the efficiency of the cogeneration system, and to heat indoor heat without driving a compressor.
Claims20
A cogeneration system comprising:
- a generator;
- a drive source which operates to drive the generator, and generates waste heat during the operation of the drive source;
- a waste heat recovering heat exchanger which recovers the waste heat of the drive source;
- at least one heating heat exchanger which heats indoor air;
- and
- a heat transfer unit which transfers heat from the waste heat recovering heat exchanger to the heating heat exchanger.
A cogeneration system comprising:
- a generator;
- a drive source which operates to drive the generator, and generates waste heat during the operation of the drive source;
- a waste heat recovering heat exchanger which recovers the waste heat of the drive source;
- at least one heating heat exchanger which heats indoor air;
- and
- a heat transfer unit which transfers heat from the waste heat recovering heat exchanger to the heating heat exchanger;
