Various methods of capacity modulation of electric motor driven heat pumps have been reviewed with a particular emphasis on variable-speed motors. The effect on the steady-state performance of the heat pump, of variation in the externally-controllable independent parameters, while the compressor...

The mathematical models of the individual components of the heat-pump system presented in Part II have been translated into computer programs. The structures of these for steady- and dynamic-state simulation are presented. The results of the simulation have been compared with some experimentally...

Various mathematical models on mechanical vapour-compression heat pumps since 1975 have been reviewed with particular emphasis on their bases and end uses. These models have been classified according to steady- and dynamicstate simulations.
