subject: Urban sewage as the sewage source heat pump to bring bright prospects - heat pump, Energy - HVAC Industry [print this page] HC HVAC & R Network Sewage Source heat pump, use of recycled urban wastewater in the heat, not only the development of a clean Energy While reducing urban heat emissions to protect the environment. Energy-saving and environmental protection is a double meaning Ground Source Heat Pump Application technology. On the other hand, using water source heat pump ground source heat pump heating is the initial investment minimum of three types of economic benefits is the most significant. One, using water source heat pump in line with national energy-saving Reduction Policies National Development and Reform Commission, Ministry of Construction, Ministry of Finance, and provincial areas have issued a large number of documents has made public a number of policy support, advocacy, encourage ground source heat pump technology. Chinese Premier Wen Jiabao in March 5, 2008 at the Eleventh National People's Congress the first meeting of the government work report that: "increasing energy conservation and emission reduction Environmental Protection Efforts to vigorously promote the reform and building energy-saving wall materials. Steady progress in urban heating system and the reform of municipal public utilities. Development and promotion of conservation, substitution, recycling of resources and pollution of the advanced and applicable technologies to implement major energy conservation technologies and demonstration projects. Services industry to develop energy-saving and environmental protection industry development as wind, solar and other clean, renewable energy. "Used to rationalize the use of sewage heat pump and increased use of natural resources base, means that development plans and policies include environmental concerns and considerations. For building a moderately prosperous society in implementing the spirit of the party's 17 large and constantly open up Chinese characteristics a new situation in the socialist cause, and vigorously promote scientific and technological progress and innovation, scientific development view, play science and technology on economic and social development of the key role, should promote the use of large-scale pollution source heat pump heating system for the heat of the city. to improve high efficiency of energy use and reduce wastage of resources, strengthen ecological and environmental areas of scientific and technological progress and innovation, development of circular economy, energy saving and environmental protection to contribute. Second, sewage source heat pump system is a mature technology, most cities have applied natural conditions, water source heat pump installation, installation costs, operating costs are relatively low. Water source heat pump currently the technology is a mature technology. We have study tour in Shenyang, Taiyuan, a city water source heat pump heating on the application. Focused on understanding the technology of sewage source heat pump system performance and the initial investment, operation and maintenance costs, etc., as well as problems in construction applications. Based on the successful experience in the draw, after investigation and research on the city, found that the city has Shenyang, Taiyuan and other cities use urban sewage source heat pump natural conditions. Shandong Zhucheng urban sewage main pipeline to help Qihe along the sides, from the hot line centers in the past, so that would make low cost pipe network. In addition, the sewage charge Fu Qi River Road in the shore, not in the road, the civil construction cost is relatively low. There are new residential sewage facilities engineering and synchronization features. Water source heat pump is the use of municipal pipe network in large urban sewage, water quality and stability, Shandong Province, the winter temperature Zhucheng water 18 to 21 degrees Celsius, with a new sewage as a heat source for district heating. Water source heat pump with heat output stability, COP value is high, good effect of heat transfer, units and compact structure, is to realize an effective way of water resources. Water source heat pump than Coal-fired boiler Environmental protection and emissions reduction than air source heat pump more than 50%, less than 80% of electric heating. It saves energy, than coal-fired boiler to save 1 / 2 fuel. As the heat source heat pump water more stable temperature throughout the year, heating coefficient than traditional air source heat pump is about 50% higher than its normal operating costs only Central air conditioning 50% ~ 60%. Therefore, the water source heat pump has a broad application prospects. Total operating costs of sewage source heat pump system is about groundwater source heat pump system, 70%, gas + air-cooled air conditioning system is running about 50% of the cost. By comparison, water source heat pump system is more economical than other options. In general, water source heat pump system, the economic benefits of the use is very significant. Zhucheng two main sewage pipe sewage stabilization of emissions at present 200 000 t / r; almost constant flow throughout the year; be able to absorb 1.6 million square meters floor space heating demand. After continually growing, so the development has great potential for water source heat pump.
