Abstract

The utility model discloses an integrated distributed energy system characterized in that: steams generated by a high pressure steam generator enter into a condenser after passing through a heating end of a stirling engine, then steam heat energy can be transmitted to refrigeration working medium pair solution, cooling water or heating domestic water which need to be heated through the condenser; pressure reduction is performed to the steams by an electronic expansion valve after the steams are condensed by the condenser, then the steams enter into an evaporator in a liquid state to experience a heat absorption and evaporation process in order to provide cold capacity used for refrigeration; and the evaporated steams are absorbed by a absorbent in a absorber, then are heated by the condenser and a solution heat exchanger, finally enter into the same circulation again through the high pressure steam generator of a high pressure pump. The stirling engine simultaneously plays a role in providing motive power for power generation and absorbing and releasing waste heat of the steams generated by the high pressure generator. The integrated distributed energy system of the utility model adopts the stirling engine based on the existing integrated distributed energy system and a absorption refrigeration system, and makes effective improvements for operation stability of a power system of the stirling engine, thus the stirling engine can perform a stable non-intermittent operation.
