Product Code:SAE J2765
Title:Procedure for Measuring System COP [Coefficient of Performance] of a Mobile Air Conditioning System on a Test Bench
Issuing Committee:Interior Climate Control Committee
Scope: 1.1This Standard applies to motor driven mobile air conditioning systems consisting of one in-car air coil (evaporator), a compressor, an expansion device, and one under-hood air coil (condenser). 1.1.1This standard can also be used for measuring systems that use electrically driven compressor if measurement of input power to compressor is carefully considered.1.1.2This standard can also be used for measuring systems that include the entire air handling system if air side pressure drop for the entire vehicle system is carefully considered.1.1.3This standard can also be used for measuring systems that include the entire front end cooling module if air side pressure drop for the entire vehicle system is carefully considered.1.1.4This standard can also be used for measuring systems that include a secondary cooling loop if the power to drive the pumps in this system is carefully considered.1.2This Standard specifies procedures, apparatus, and instrumentation that will produce accurate steady state capacity and efficiency data for refrigerant components.1.3This Standard does not:1.3.1Specify tests for dual evaporator systems,1.3.2Specify transient test methods, 1.3.3Make recommendations for safety1.3.4Specify tests for production, specification compliance, or field testing of mobile air conditioning systems.
