Almost classification: sewage source heat pump is a water source heat pump, it is relying on the internal refrigerant heat pump unit of state cycle of change, winter to receive heat from the wastewater by the warming of the heat pump unit for the construction of heating, the summer after a heat pump unit the construction of objects in the heat transfer to the sewage and then to complete cooling. Energy efficient, green, safe reliable, the use of a machine, such as bulge strengths. Sewage source heat pump system to complete the bookmakers to take over the application of urban waste heat, turning waste into wealth, new skills for renewable, clean power applications, and fit to continue the establishment of capital-saving situation fraternity society requirements. Source heat pump system skills and the urban sewage to link far-reaching significance in the expansion of urban sewage are typically limited to, expanding the effectiveness of urban wastewater management.

Features and advantages of the two sewage source heat pump

China's northern regions, winter heating is relying on the combustion of coal, oil, natural gas and other fossil fuels to obtain. Heating and environmental protection has become a pair of difficult to deal with the contradictions. Urban sewage is cold northern geographical scarce and rare heat pump source. Its temperature seasons a year relatively unchanged, than the situation in winter air temperature, summer is lower than the situation of air temperature, this temperature characteristics that make the sewage source heat pump is higher than the traditional air-conditioning system operating efficiency, energy efficiency and throttle operating costs results obvious.

Sewage source heat pump units of untreated sewage as heat source, the winter collection of low-level heat from the sewage, with the heat pump system, after consuming the local electricity, indoor heating energy supply; took out the indoor heat in the summer, the release of into the water to reach the goal of the summer air conditioning. It has the following characteristics:

Environmental benefits

Sewage source heat pump is the application of urban waste heat as a heat source, heating and air conditioning systems for energy conversion, waste water through the heat exchanger equipment left behind after the cold or heat back to the trunk sewers, sewage and other equipment or systems does not touch the sewage closed cycle do not pollute the other device or water system. Eliminating the need for coal, gas, natural oil, boiler room systems in heating, there is no combustion process, to prevent smoke pollution; cooling eliminates the need for cooling towers to prevent the noise of the cooling tower and mold contamination. Does not occur any waste, wastewater, waste gas and dust, the situation is obvious benefits. Amounted to 46.4 billion m3 of sewage can throttle the amount of coal 033 million tons, the national annual energy consumption of 30 million tonnes of coal, accounting, reached 1.1% by the first power of the HVAC-consuming amount of 1 billion tons standard coal accounted for 3.3%. Annual reduction of emissions amounted to 720,000 tons.

(2) energy efficient

Winter, sewage body temperature higher than the situation of air temperature, evaporation temperature of the heat pump cycle advances, energy efficiency has improved. Summer water temperatures warmer than air temperature situation is low, so the refrigeration condensing temperature is reduced, better than air-cooled and the cooling tower cooling results, the progress of unit efficiency.

Has available cold heat unit volume of sewage, sewage source heat pump system is required for the construction of the material heating 1.33 the first power-consuming, relatively coal-fired systems can throttle 0.64 the first power.

Set of unit volume of sewage to 100m3 meter, can the application of sensible heat temperature difference is 5 ° C may be applied to the cold heat = 2.1 × 106kJ. Heating: can throttle power (coal) 1.34 × 106kJ, which is equivalent to 71.3 kg (22.8) coal-fired. Can be the first throttle power (gas) 0.651 × 106kJ, which is equivalent to 40.7m3 (48.8 million) gas. Refrigeration throttle once power (coal) 0.357 × 106kJ, equivalent to 19 kg (6.1 million) coal-fired. Can be the first throttle power (gas) 0.168 × 106kJ, which is equivalent to 10.5m3 (12.6 million) gas.

(3) running the same solid

The temperature of the water year four o'clock relatively unchanged shaken limitations far less than the change of air, is a good heat pump heat and air conditioning cold source, the water temperature more constant feature of the heat pump units operate more secure, the same guarantee the system's efficiency and economy. Does not exist winter air source heat pump defrost and difficult problems.

4 of a machine, use the limitations of a wide

This heat pump system, heating, air conditioning, more than one machine, a system can exchange the two sets of installation or system of the original boiler plus air conditioning. Application of urban sewage of the city sewage heat pump system, take thermal heating in winter, summer heat cooling throughout the year to take the heat supply career hot water, hot water supply purposes of the local free career summer air conditioning season. A system of dual-use winter and summer, and completion of the Tri.
