Theoretical Research and Optimization in Variable Condition of Water Source Heat Pump

This paper considers the centralized energy supply system model which include the winter heating and summer cooling, The author carries on the analysis and the computation through the compressor, condenser and evaporator´s power, the heat transfer and the flow quality, then establishes a steady-state mathematical model of water Source Heat Pump, which applied thermodynamics theory, the parameter distribution and the incident cross-correlation method. In view of the constructed model, the author establishes a computational procedure which take the heat output, cooing capacity and COP as the objective function. In the above foundation, the author analyzes operating characteristic and the inherent laws in variable condition comprehensively, then studies the primary factor which influence the thermal energy performance of water source heat pump ,at last the author gives the concrete effect and the optimized suggestion.
