Abstract

With global interest in energy saving and emission reduction, the combination of waste water energy recycling and solar energy has attracted great attention. In this work, a solar-assisted waste water source heat pump hot water system was built in TRNSYS. The sensitivity analysis of different factors on the annual heating performance coefficient of the system was conducted and the optimal parameters were selected to improve the basic scheme. The results revealed that the COPsys and COPHP were highly related to the pump flowrate and the storage capacity of heat exchange tank, but the azimuth and inclination angle of solar collector have slight influence on them. Moreover, the increase of heating capacity of solar collector will lead to the decrease of COPHP, while resulting in the decrease of the heat pump power consumption. The suitable pump flowrate is 4.6 m3/h and the appropriate volume of the heat exchange tank is 1 m3. The best azimuth angle and inclination angle of the solar collector are 4° south by east and 42°, respectively. The improved system has more stable hot water temperature in winter with significant decrease of the energy consumption.
