污水源热泵（Sewage source heat pump） Fig. 1 flow chart of sewage source heat pump system The sewage source heat pump, mainly in the city sewage as cold and heat source for the extraction and storage of energy, material circulation changes the internal refrigerant heat pump system, consume a small amount of electricity, an innovative technology so as to achieve the effect of cooling and heating. Compared with other heat sources, the key technology and difficulty of sewage source heat pump are blocking, pollution prevention and corrosion prevention. Edit this section of sewage source heat pump operating principle Working principle flow chart of sewage source heat pump The main working principle of sewage source heat pump is the use of sewage source heat pump compressor system, consume a small amount of electrical energy, make low energy in the water extraction in winter, for users of heating, the indoor heat extraction , released into the water, thereby reducing the room temperature, achieve the cooling effect. The energy flow is the use of heat pump energy (electricity) all the heat absorbed (i.e. to absorb heat energy +) with high-temperature heat source row to lose, and the energy consumption effect is to make medium compressed to high pressure and high temperature, so as to achieve the absorption of low temperature heat source heat energy. The sewage source heat pump system is composed of water source, water pipe, cold and hot water pipeline, water source system, heat pump system, end system and so on. According to whether the raw sewage is directly into the heat pump unit, evaporator or condenser, the system can be divided into two ways: direct utilization and indirect utilization. Direct use refers to the sewage heat through the heat pump recovery after delivery to the heating and air conditioning in buildings; indirect use refers to the sewage through the heat exchanger for heat exchange, then the sewage recycles the heat transported to the building through the heat
