Combined cold, heat and power supply apparatus and method with utilization of earth source absorption type refrigeration heat pump

Abstract

The invention discloses a combined cooling heat and power supplying device and a method for a ground source absorption type refrigeration-heat pump. The invention takes natural gas (or other combustible gases) as fuel, after high-temperature flue gas generated by the combustion of the fuel in a combustion chamber drives a gas turbine to generate power, the exhausted flue gas is firstly taken as compensation energy for an absorption type refrigeration-heat pump device, and then heat is supplied to a hot water heat exchanger. The hot water heat exchanger can supply domestic hot water to the external all the year round. The device comprises a power supply part, a refrigeration-heat part and a domestic hot water supply part, wherein the power supply part comprises the combustion chamber (A), the gas turbine (C) and a generator (D); the refrigeration-heat part comprises an afterburning chamber (B), the absorption type refrigeration-heat pump device (I), a split type heat pipe heat exchanger evaporation section (F), a split type heat pipe heat exchanger condensation section (K), a geothermal source buried pipe heat exchanger (S) and an air conditioning user pump (U); the absorption type refrigeration-heat pump device (I) comprises a generator (J), a condensator (L), an evaporator (N) and an absorber (P); the domestic hot water supply part comprises a hot water heat exchanger (G) and a water supply pump (W) of the hot water heat exchanger.

Description

technical field [0001] The patent of the present invention relates to a cogeneration system of heat, electricity and cooling, especially a cogeneration system of heat, electricity and cooling using a ground source absorption refrigeration-heat pump.
