热泵热水器中R1234ze(E)/HCs混合工质替代R134a的理论研究
Theoretical Study on the Replacement of R134a by R1234ze(E)/HCs Mixture in Heat Pump Water Heater
摘要
Abstract
In order to replace the R134a used on the heat pump water heater,MIX01(m(R1234ze(E))∶m(R290)=40∶60),MIX02(m(R1234ze(E))∶m(R600)=85∶15),MIX03(m(R1234ze(E))∶m(R600a)=75∶25)were studied in this paper.The thermodynamic model of the heat pump system was established.Matlab was used for theoretical circular calculation of the mixtures by employing property parameters from Refprop de-veloped by NIST.According to the national standard,the three mixed working fluids were calculated under vari-able working conditions,and compared with the working fluid R134a.The results showed that the ozone depres-sion potential(ODP)of the three R1234ze(E)/HCs working fluids was 0,and the global warming potential(GWP)was less than 20.All of them belong to near-azeotropic working fluids.Among them,MIX01 was superi-or to R134a in terms of exhaust temperature,compression ratio and volumetric heating capacity.关键词
