| Abstract: | The thermodynamic features of R134a and R290 are compared to analyze the feasibility of replacing R134a with R290 in large volume commercial display cabinet （LVCDC） , and the performance of LVCDC using R290 is tested. The test results show that, comparing with R134a system,R290 system has a faster cooling speed, lower en- ergy consumption and noise, and less condenser material. The safety requirements of R290 system can be achieved by controlling the refrigerant charge amount and taking the suitable safe measures. |
