The cooling and heating research of an underground water source heat pump system in Qian'an

In recent years, the promotion of renewable energy has been used in many Qian'an's buildings, and in which the use of groundwater source heat pump technology is particularly widespread. This work is focused on the comprehensive economic analysis and energy efficiency evaluation of groundwater source heat pump system for a building in the Qian'an City. As the data analysis shown, we can see that the summer average COP is 2.46 and that of winter is 2.27. Meanwhile, the load fluctuations of the day's operating parameter are relatively stable. In combination with engineering example analysis of factors influencing the operating efficiency, it is concluded that should be adopted "large temperature difference, small flow" operation mode, the comprehensive analysis to get the best combining site. Through this research, the author hopes to further enhance the energy conserving potential of the underground water source heat pump system in Qian'an region to provide important data basis, and operation and management of the maintenance of the relevant system has a certain engineering guidance.
