| Abstract: | To obtain the low temperature of 150 K,the design of four-stage auto-cascade refrigeration(ACR) was set up.The R134a/R23/R14/R50 refrigerant mixture was used in the system.The each point's parameters of the system were calculated using NIST.According to the literatures and the empirical formula,the compressor,condenser,evaporator and heat exchanger were designed and choosed. |
