Energy efficiency analysis of middle-deep hydrothermal geothermal heat pump heating system

Abstract

With more and more application cases of the middle-deep hydrothermal heating technology, in practical applications, the energy efficiency issues of the heating system are increasingly prominent, and the heating heat pump system is the core of the entire heating system, and its energy efficiency has directly affected the economics of the heat system. This paper mainly analyzes the energy efficiency of the heating system for the one side temperature and host side temperature of the plate change system and the heat pump system, and uses the selection software provided by the heat pump unit manufacturer, combines the operation data of the actual engineering case, and analysis of the effects of comparison of different into and out of water temperature on the energy efficiency of the heat pump unit, summarizes the energy-efficient inlet and outlet temperature range with the energy efficiency of the heat pump system, and provides reference to the actual engineering application of the middle-deep hydrothermal heating heat pump system.
