Abstract
Air source heat pump heating technology has been widely used in the clean heating engineering,such as reducing and replacing coal heating in North China.With the development of low-temperature air source heat pump heating technology,it is technically feasible to apply and popularize the clean alternative energy heating technology into part of Northeast China.This article analyzes the heating performance of low-temperature air source heat pump coupled with scroll compressor and enhanced vapor injection (EVI) in terms of thermodynamic theory and experimental comparison.According to the results,under the condition that the simulated outdoor air temperature is-25 ℃ and RH is 86%,the COPh of a 10 hp EVI is 1.38,which can meet the heating demand in part of Northeast China.Through the running test of an engineering example applying in Suizhong County,Liaoning Province,it is verified for the technical feasibility to apply the EVI in the heating engineering in part of Northeast China.But to make it have a better economic feasibility,it still needs to match other economical energy saving technology participating in saving the operation cost,and needs the supporting policies of government,such as fiscal subsidy,to recover the initial investment together.关键词
