On the basis of analyzing the thermodynamic properties and cycle performance of pure refrigerants, the paper optimizes their concentration while screening NARMs used in wide variable-temperature heat source. The practical applications of NARMs, such as R22/R123, R123/R125 etc., are studied in geothermal heat pump, seawater heat pump, air dehumidification system and dual-evaporator domestic refrigerator.
