Alternate Refrigerant Consistency Criteria for Use in Mobile Air-Conditioning Systems

SAE J 1658-1999 发布历史

This SAE Recommended Practice applies to refrigerant blends (multicomponent refrigerants) intended for use as retrofit refrigerants to replace CFC-12 (R12) in mobile air conditioning systems. Since the composition of non-azeotropic refrigerant mixtures changes as refrigerant is los, either through the vapor phase or the liquid phase, the method of charging air conditioning systems is important. The purpose of this document is to determine the proper refrigerant phase, liquid or vapor, for system charging by relating system performance changes t the charging method. This document is complete only when combined with the requirements of SAE J1657
