Abstract
This paper lists the basic physical parameters of commonly used working fluids of R290,R32,R410A,and R134a household heat pump water heater.Based on a single-stage vapor compression thermodynamic cycle model,the cycle characteristics of the four working fluids are analyzed under different condensation temperatures of 35 to 70℃.The results show that under the same conditions,R290 has low exhaust temperature,exhaust pressure and compression ratio,and is less sensitive to changes in condensation temperature,and has better exhaust characteristics;The R290 does not have many advantages in terms of heating capacity.In order to achieve the same heating capacity level as the R32 and R410A systems,the R290 system requires a larger compressor displacement,but it has better cycle COP and reduces system energy consumption.More potential.关键词
