| Solar energy is known to be a type of clean renewable energy,which is inexhaustible and endless.As an 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 prospectBased on the heat source transformation of central hot water supply system in a community of BaBaiShang in DaQing,this paper combined with the advantages and disadvantages of solar collector technology,air source heat pump technology and water source heat pump technology,and put forward four multi-heat-source heating schemes:solar collector and electric boosting system,air source heat pump and electric boosting system,water source heat pump system(using heat exchanger in heating period and groundwater in non-heating period),solar collector and air source heat pump and water source heat pump compound system.It also analyzed the operation mode of each system,the advantages and disadvantages of various solar collectors,performances of air source heat pump and water source heat pump,meanwhile,It introduces the calculation method of area and noise of flat-plate solar collector,control principle and implementation of each system.Finally,It concludes that solar collector and air source heat pump and water source heat pump compound system is the most reasonable by economic and feasibility analysis.It also verified the correctness of economic analysis by operation data of this scheme,the results showed that the system has obvious energy saving effect and high popularization value. |
