Abstract：
Used in Cold Region-Shenyang an energy-saving building in the air-ground source dual heat source heat pump system is introduced in this paper, the design of air-soil dual heat source heat pump system effectively using the photo-voltaic photothermal conversion part of heat as a source of heat, to avoid the air source heat pump in cold area of frosting problem, while reducing the soil source heat pump of cloth well area. Using TRNSYS software simulation model is established, the system for selecting the main module, and on the performance of dual heat source heat pump were two seasons of winter and summer simulation analysis. The results prove that the dual heat source heat pump is more stable than the single soil source heat pump system operating and the cop values are high, is more reliable.
