Calculation of Heating Capacity of Heat Pump Assisted Solar Water Heating System
The calculation of heating capacity of heat pump in the solar water heating system,which is the key parameter in pump selection and design of the tank,has not been reported in the literatures so far.Based on a single tank solar water heating system,this article makes an analysis of temperature distribution in water tank when only heat pump works under continuous rainy weather.And this article is first proposed the calculation of the heating capacity of the heat pump.The heating capacity of one solar water heating system is calculated by this way,and the ratio of the heating capacity and the hourly average heat consumption is given.For the general heat pump assisted solar water heating systems,it is more appropriate that the relative height of thermal storage area is 0.20 to 0.25 and the maximum running time of heat pump is 8 hours daily.
