Research and Analysis of Combined Operational Mode of Solar Energy Hot Water Heating System and Sewage Source Heat Pump Units

Based on the test studies of solar hot water system and water source heat pump units combined heating system and its theory analyses, we discussed the IPLV and electricity consumption of each major equipment in the system under different combined operation mode and control strategies, then it is concluded the best system equipment selection, best joint operation mode, the operation of the best control strategy theory of a complete set of suitable for solar energy and water source heat pump in the joint use,that eventually concluded that it is suitable for cold region of composite energy heating system optimum heating mode.
