NONFLAMMABLE MIXED REFRIGERANTS FOR USE WITH VERY LOW TEMPERATURE THROTTLE-CYCLE REFRIGERATION SYSTEMS

Title:

NONFLAMMABLE MIXED REFRIGERANTS FOR USE WITH VERY LOW TEMPERATURE THROTTLE-CYCLE REFRIGERATION SYSTEMS

Document Type and Number:

Japanese Patent JP2009155660

Kind Code:

A

Abstract:

To provide refrigerant blends which require no hardware or oil composition changes to maintain temperatures, pressures and capacity substantially unchanged in a refrigeration system.

In the nonflammable refrigerant blends for use with very low temperature throttle-cycle refrigeration systems, refrigerants containing HCFC's are replaced with new blends by using R-236fa and R-125, or R-125 with R-245fa, or R-236ea, or R-134a with R-236fa in place of HCFC's.
