B2-03 Research of the air source heat pump and the water system

By adjusting the operation parameters of an air source heat pump system e.g. decreasing the supply water temperature in cooling operation mode or increasing the supply water temperature in heating operation mode, the air conditioning system can be running more economically while the efficiency decreases. In this paper, we tested the relations among the operation parameters of the system, water system parameters and the overall cost during the life cycle of the heat pump system, we also made the evaluation on energy efficiency and technology of an actual project cases and proposes an optimization option.
