摘要
空气源热泵作为冬季燃煤供热的替代品,具有绿色、高效、节能环保等特点,低温环境下空气源热泵系统能效比明显降低,结合国内外研究现状,总结了几种复合热泵性能提升技术,如热水式复合换热器、PV/T式复合换热器、传统的循环式复合热泵,并对它们的特点及问题进行了分析,提出一种空气-水双热源式热泵系统,对该系统的未来进行了展望,旨在指出双热源复合式热泵的巨大推广价值。
As a substitute for coal-fired heating in winter,air source heat pump has the characteristics of green,high efficiency,energy conservation and environmental protection.The energy efficiency ratio of air source heat pump system is significantly reduced in low temperature environment.This paper summarizes several performance improvement technologies of composite heat pump,such as hot water composite heat exchanger,PV/T composite heat exchanger,and traditional circulating composite heat pump,and analyzes their characteristics and problems,an air-water dual heat source heat pump system is proposed,and the future of the system is prospected,aiming to point out the great promotion value of the dual heat source heat pump technology.
