By comparing and analyzing the characteristics of R290 refrigerant and R410a refrigerant, the optimized design scheme of the R410a system for a desiccant cooling system is transformed into a R290 system. The optimiza-tion design of system is carried out through the compressor displacement, the cooling medium flow volume, and the two tube diameter selection principle. R410A system transformation for R290 compressor should be selected large displacement, displacement to increase by about 71%; refrigerant perfusion can be reduced by 50%; evaporator design selection process is short, condenser design should select tubular diameter.
