Description / Abstract:
The purpose of this SAE Recommended Practice is to establish
uniform test procedures for measuring and rating air delivery and
cooling capacity of truck and off-road self-propelled work machines
used in earth moving, agriculture, and forestry air-conditioner
evaporator assemblies. It is the intent to measure only the actual
cooling capacity of the evaporator. It is not the intent of this
document to rate and compare the performance of the total vehicle
air-conditioning system.
This procedure is designed to provide truck and off-road
self-propelled work machines used in earth moving, agriculture, and
forestry manufacturers and air conditioning system suppliers with a
cost-effective, standardized test method and calculations for
measuring and rating air delivery and cooling capacity of truck cab
air-conditioner evaporator assemblies. This procedure relates to
HFC-134a (R-134a) refrigerant system.
