SAE J3094_202004
Test Procedure for Internal Heat Exchangers of Mobile Air-Conditioning Systems with R-134a or R-1234yf Refrigerantstandard by SAE International, 04/02/2020
The purpose of this SAE Standard is to define a common set of thermodynamic test conditions to evaluate internal heat exchangers for use with R-134a and R-1234yf refrigerants in mobile air-conditioning systems. This standard can be used to test actual vehicle IHX designs or standardized IHX samples, which can be used for comparison based on a common length and shape.
