An Integrated Air Conditioning (AC) Circuit and Cooling Circuit Simulation Model 2001-01-1691

This paper describes the development of an AC circuit simulation capability, within the FLOWMASTER2 computer program, that has been specifically designed to operate in conjunction with other thermal systems, such as the engine cooling circuit. The models used for the major components of an AC system (compressor, condenser, evaporator and expansion device) are briefly described, with some comparison with the available measurements. An example of a combined simulation of an AC system with an engine cooling circuit is also presented.
