Presents an analysis of using a heat pump to provide heating and cooling for the passenger compartment of motor cars through simulations using both R-12 and R134a, with a mobile heat pump model. The main purposes is to evaluate the effectiveness of currently available and employed motor car air conditioning components as they perform in a heating mode. Additionally, makes comparisons and draws conclusions concerning the relative performances of R12 and R134a.
