Abstract   By comparision, the relative merits of developing geothermal energy and air-source heatpump products
were expounded, respectively. Based on air-source heatpump products’ defects of easily frosting, heat lacking and poor
performance, corresponding measures were suggested to make their application at low ambient temperature more
simple to implement. In allusion to the discuss on evaporation temperature of air-source, the method of allying it to
waste heat water source was proposed. Meanwhile, by applying the heat and cold effect of the refrigeration system,
some Air-source Air-conditioning Heatpump Water Heater products were exploited, which improved the overall energy
efficiency ratio (EER) of heatpump products. In view of compared analysis on product performance, manufacturing cost,
use cost and develop difficulty, a conclusion can be drawn that it should be cautious to develop geothermal energy
products while there is still a spacious room for the research and development of air-source heatpump products.
