Sažetak
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 use of graphic interface enabled analyses of working conditions at operating limits of the heat pump. Results of the dynamic heat pump model were confirmed by comparison with experimental data.
