This article has made a full analysis to the small temperature difference between intlet and outlet water of air-source heat pump which is located in Xianlin School district of Nan jing normal University.

The Study of the Air Source Heat Pump during the Reverse—Cycle Bypass Defrost;

The reasons were analyzed from the points of how efficiently GSHP uses the underground thermal energy and EER comparison of GSHP with the air source heat pump.

Through the calculations, this paper analyzes the feasibility of the application of the air cooled heat pump units in Ningbo Area, gives out the cal culating methods, and discusses the problems that should be noticed during the p rocess of the application of the air cooled heat pumps.

A Back Propagation Network was built to choose proper air cooled heat pump systems.

Comparing with the static design method, the excellences at the dynamic emulation and design about the underground buildings air cooled heat pump systems were shown.
