Appling urban untreated sewage as a cool and heat source of the heat pump air conditioning system is considered to be an effective way to develop urban sewage resource and a critical technique to serve the building energy system.Applications of technical difficulties are to solve the jam on sewage dirt to tube of heat exchanger and pipes. The multi-filter surface backwash technology is used to separate the suspended solids from the sewage and clean the dirt on the grille. By describing the filtration technique in the sewage source heat pump system to introduce the principle of operation and control process of the multi-filter surface backwash technology. By using in commercialese, the technology is proved to be feasible and reliability. These methods could serve as a reference for designing and application untreated sewage source heat pump systems.

Pile foundation thermal response test method was adopted to measure the heat transfer capacity of the pile foundation U-pipe heat exchanger. The heat pump system of pile foundation buried pipe was designed. BIN method was adopted to calculate the annual dynamic load of office in Shanghai and annual energy consumption, and its energy-saving effect was determined by comparing with the air-cooled heat pump air conditioning system. Finally, annual cost method was employed to study the investment and annual operating expenses of pile foundation buried pipe heat pump air conditioner systems, and their economy, advantages and disadvantages by comparing with those of the air-cooled heat pump air conditioning system were analyzed.

The extremely poor sewage quality could make the sewage heat utilization difficult. The paper introduces the content and distribution property of the sewage dirt. For the dirt properties and project experience, it proposes the two basic points of the anti-blocking technique in sewage source heat pump system: filtering surface continuous regeneration and dirt continuous reduction and the request for filtering pore size parameters. It also describes the principle of filtering surface hydraulic continuous regenerative technique and establishes its mathematical model and design method of the device. The calculation and application result indicates that filtering surface hydraulic continuous regenerative technique can guarantee the filtering effect and operation flow stable.
