THE STRUCTURE OF HEAT TRANSFER FLUID IN MICRO COMBINED HEAT AND POWER UNIT

摘要

The present invention provides a circulation structure of a heating medium in a micro combined heat and power generator wherein a low temperature heating medium heat-exchanged in a hot water tank exchanges heat with low temperature inflow direct water flowing through a direct water line, and then is returned to a stirling engine through a heating medium return line to lower a temperature of the stirling engine to maintain high power generation efficiency. Also, since hot water usage can be detected by a flow sensor disposed on one side of the direct water line, setting temperatures when using hot water and by natural heat radiation can be defined to prevent durability degradation caused by repeating frequent running/stopping of the stirling engine and expect smooth operation.
