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 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...

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.

A mathematical model to simulate the steady- and dynamic-state behaviour of an existing water-to-water electric-motor driven heat-pump has been evolved. The condenser area on the working fluid side has been divided into two sections: namely, condensing section and sub-cooling section, while the...

Heat pump assisted distillation with an external working fluid is one of the most obvious methods to reduce the energy consumption in a distillation process. The heat pump working fluid extracts heat from the top of the column, increases the temperature of the recovered heat and recycles it to...

The design sequence of a heat pump is described. Various design aspects of a heat pump are discussed with reference to individual components of the system. Some of the common refrigerants have been theoretically analysed for their suitability as heat pump working fluids. Rankine coefficients of...
