Sewage source heat pump technology - new breakthroughs in the field of building energy conservation made the Seventeenth Party Congress: "adhere to the conservation and protection of the environment, the basic state policy of the Chinese people's vital interests and the survival and development. Have to build resource-saving, environment-friendly society on the industrialization and modernization strategy in a prominent position, implemented in every organization and family. " At the same time achieving the goal of building a moderately prosperous society in the new requirements clearly pointed out: "Building a conservation culture by basically forming an energy resources and protect the ecological environment of the industrial structure, growth, consumption patterns." The energy consumption of buildings is the main social sectors, which use more than any other energy industry is the main factor affecting climate change. In China, building energy consumption accounted for 30% of total energy consumption, building energy for the country's greenhouse gas emissions "contribution rate" has reached 25%. China's existing building stock of 44 billion square meters, and most are not saving, with the total rising construction and upgrading of living comfort, building energy consumption will continue to rise. Because of changes to speed up the construction of green energy-saving and emission reduction, mitigation of global warming is of great significance. Urban sewage is rare HVAC important new energy, a huge urban sewage water, suitable temperature, with the existing water source heat pump operating temperature of evaporation and condensation have a good match. Urban sewage source heat pump system is not only an important social significance, but also shows the beginning of sewage source heat pump systems have lower investment and operating costs, higher utilization of primary energy system, the application has great potential. Northern China, winter heating mainly rely on coal, oil, natural gas, the burning of fossil fuels to get. Heating and environmental protection become a pair of difficult to resolve conflicts. Urban sewage is rare in northern cold regions heat pump source. It is a relatively stable temperature throughout the year, the winter than the ambient air temperature is high, in summer than the ambient air temperature is low, this makes the water source heat pump temperature characteristics than traditional air conditioning system efficiency is higher, energy efficiency and savings in operating costs results are obvious. Sewage source heat pump to untreated sewage as heat source, the winter low-grade heat from sewage collection, with the heat pump system, by consuming part of the energy, the energy supply will be achieved by indoor heating; in the summer heat out of the indoor, released into the water to achieve the purpose of air conditioning in summer. Sewage source heat pump system and heat source, winter heating, summer air-conditioning and hot water supply throughout the year, eliminating the need for coal in heating, gas and fuel oil boiler system, there is no combustion process, to avoid the smoke pollution, eliminating the need for refrigeration cooling tower, cooling tower to avoid the noise and mold pollution, atmospheric pollution. Does not produce any waste, wastewater, waste gas and dust, a significant environmental benefits.
