Title: The Oak Ridge National Laboratory automobile heat pump model: User`s guide

Technical Report ·
DOI:https://doi.org/10.2172/10176877· OSTI ID:10176877

A computer program has been developed to predict the steady-state performance of vapor compression automobile air conditioners and heat pumps. The code is based on the residential heat pump model developed at Oak Ridge National Laboratory. Most calculations are based on fundamental physical principles, in conjunction with generalized correlations available in the research literature. Automobile air conditioning components that can be specified as inputs to the program include open and hermetic compressors; finned tube condensers; finned tube and plate-fin style evaporators; thermal expansion valve, capillary tube and short tube expansion devices; refrigerant mass; evaporator pressure regulator; and all interconnecting tubing. The program can be used with a variety of refrigerants, including R134a. Methodologies are discussed for using the model as a tool for designing all new systems or, alternatively, as a tool for simulating a known system for a variety of operating conditions.
