Research On Operation Condition Of The Solar Assisted Water Source Heat Pump System

Solar energy is known to be a type of clean renewable energy, which is inexhaustible and endless.As a energy conservation of green air-conditioning technology,heat pump can promote the useless low grade thermal energy to useful energy for the purpose of improving the energy utilization efficiency and saving energy.By integrating solar and water source heat pump,not only solar and source energy utilization efficiency,but also energy and environmental problems faced these days are alleviated,it has a bright prospect.Based on the combination of advantages and disadvantages of solar assisted heat pump and water source heat pump technology, the concept of solar assisted water source heat pump system is proposed and the working principle, operation mode ,function are also introduced.The characteristic of the solar radiation and calculation model are proposed in the paper. The heat transfer process of the flat plat solar collector is analyzed. The paper deals with the modelling of the main components of a solar hot water system. Mathematical model is developed to describe the thermal behaviour and energy balance of different solar collectors and hot water storage tanks. Performance characteristics under different operation conditions of solar assisted water source heat pump system are analyzedAn example in Zhuhai is proposed and the changement of the parameters in different operation conditions is analyzed. The performance characteristics of the Solar assisted water source Heat Pump System in various operating conditions is studied to provide the reference for design and operation management of Solar assisted water source heat pump system. Finally, economic analysis of the solar assisted water source heat pump system have more advantage than common energy heater.
