OZONE-FRIENDLY WORKING MIXTURE FOR REFRIGERATION EQUIPMENT

Title:

OZONE-FRIENDLY WORKING MIXTURE FOR REFRIGERATION EQUIPMENT

Document Type and Number:

WIPO Patent Application WO/1995/009214

Kind Code:

A1

Abstract:

The invention relates to refrigeration technology and can be used in medium-temperature refrigeration equipment, air conditioners including those used in motor vehicles, in heat pumps, and for research purposes. According to the present invention, the proposed ozone-friendly working mixtures contain sulphur hexafluoride and at least one of the following substances: octafluoropropane, octafluorocyclobutane, decafluorobutane. In addition, hexafluoroethane and/or tetrafluoromethane can be added to the mixture in quantities of up to 30 wt %. The optimal compositions of appropriate binary mixtures are also proposed. These ozone-friendly working mixtures can be used in existing refrigeration equipment without any fundamental modifications being made to that equipment.
