Abstract:In part I of this paper, the developing processes of sewage water source heat pump and air conditioning system in north Europe and Japan are depicted. And the newest progress and developing direction of the sewage water intake and heat transfer technologies about the sewage water source heat pump and air conditioning system are introduced. Here, the researches on the sewage water source heat pump in China are summarized. The current problems in engineering application actualities are analyzed. And it pointed out that developed new sewage intake technology is necessary to avoid the disadvantage influence on the COP of the heat pump unit due to inner leakage for the sewage intake technology according to the deficiency of the current technology and the defouling and enhanced heat transfer are key technology problems of the sewage water source heat pump and air conditioning in the future after solving the sewage water intake technology.
