The invention discloses a thermal mass decoupling heat exchanger and a thermal mass decoupling method thereof in the technical field of energy utilizing. The thermal mass decoupling heat exchanger isa two-stage compression thermal mass decoupling heat exchanger, and is composed of a phase transformation heat exchanger, an absorbing tower, a cooler, a heater, a desorbing device, a compressor, a circulation pump, a throttling valve, padding, a hot water pipeline, a cold water pipeline, a heat pipe and a connection pipeline. The thermal mass decoupling heat exchanger adopts a heat pipe heat exchanging manner, the heat exchanger flow path of two-stage compression and thermal mass decoupling is built, so that the irreversible loss in the heat exchanging process of the heat exchanger and a coldsource and a hot source is remarkably reduced, and efficient transmission of heat under a large temperature difference is achieved; and efficient heat exchanging of a low temperature object and a high temperature object is achieved, heat can be extracted from the low temperature object such as soil, underground water, air or industrial waste heat, high temperature water, steam or chemical media are obtained, and remarkable technological and economical advantages are achieved due to remarkable improvement of the system efficiency.

Description

technical field [0001] The invention belongs to the technical field of energy utilization, and in particular relates to a heat-mass decoupling heat exchanger and a heat-mass decoupling method thereof, in particular to a high-efficiency heat exchanger for extracting heat from low-temperature objects to heat high-temperature objects. Background technique [0002] There are a lot of heat exchange processes in the field of energy utilization, according to the second law of thermodynamics: heat can only spontaneously transfer from high temperature objects to low temperature objects. If it is necessary to transfer heat from a low temperature object to a high temperature object, a certain cost is required. The temperature difference is the driving force for heat transfer. When heat needs to be transferred from a high temperature object to a low temperature object, only a conventional heat exchanger is required, but if heat is transferred from a low temperature object to a high temp...

AI Technical Summary

Problems solved by technology

Conventional heat pump equipment is limited by the performance and flow of the circulating working fluid, and can only work within a limited temperature range. If the temperature difference between the low-temperature object and the high-temperature object is large, its efficiency will be greatly reduced, so the economy of the system will be significantly reduced. It is difficult to actually promote the application
