Abstract
A dynamic numerical model of a compression vapor cycle heat pump is
presented. The model is based on mass and energy balances, thermodynamic and
thermal properties of the working fluid and constructive characteristics of heat
pump components. The model enables the prediction of temporal and spatial
distribution of refrigerant temperatures, pressures and mass flows, as well as
water temperatures for variable boundary conditions that occur during the heat
pump operation. Experimentation has been performed on a laboratory test rig.
Refrigerant pressures and temperatures, compressor electric power consumption,
as well as water temperatures and mass flows were measured. The measurement
of dynamic operating conditions was successfully performed using the data
acquisition system controlled by personal computer. The u
