Summary

Two-stage compression using a compound compressor is widely adopted for ultra-super low-temperature cold warehouses. For power-saving reasons, the cascade cooling system is adopted in the same manner, and at present, R23 on the low temperature side/R22 on the high temperature side are used. In the future, R404A, R507A and other HFC refrigerants will be used as substitutes of R22. Efficiency data are given for some combinations, including one involving the use of NH3.
