THE USE OF R22 FOR LOW TEMPERATURE SYSTEMS.

Author(s) : SMITH G. R.

Type of article: Article

Summary

THE AUTHOR SUGGESTS SINGLE STAGE R502 SYSTEMS IN SUPERMARKET TYPE INSTALLATIONS MAY BE RETROFITTED TO OPERATE WITH R22 BY THE CHANGE TO TWO-STAGE OPERATION. THIS MAY BE DONE BY USING THE SMALLER SIZES OF INTERNALLY COMPOUNDED R22 COMPRESSORS NOW AVAILABLE, OR BY USING SEPARATE COMPRESSORS FOR EACH STAE BOTH ARRANGEMENTS CAN INCLUDE A LIQUID SUBCOOLER WITH OVERSPILL FEED TO COOL THE INTERSTAGE GAS BY INJECTION. TWO COMPRESSOR INSTALLATIONS WILL REQUIRE LEVEL OPERATED OIL RETURN FROM A COMMON SEPARATOR. D.W.H.
