Energy-saving and affordable housing policies help sewage source heat pumps

Editor's note: The sewage source is mainly used as a cold and heat source for extracting and storing energy from municipal sewage. With the help of the change of the state cycle of the refrigerant in the heat pump system, a small amount of electric energy is consumed, thereby achieving an innovative cooling and heating effect. . On August 31st, Beijing released the energy-saving plan for civil buildings during the 12th Five-Year Plan period. It will play a positive role in demonstration and use in September. . .

The so-called sewage source heat pump mainly uses urban sewage as a source of cold and heat for extracting and storing energy, and uses the internal circulation of the refrigerant in the heat pump system to change the state of the refrigerant, consuming a small amount of electric energy, thereby achieving an innovative cooling and heating effect. . Compared with other heat sources, the key technology and difficulty of the sewage source heat pump are anti-clogging, anti-pollution and anti-corrosion.

On August 31, Beijing Municipality issued the “Energy Conservation Plan for Civil Buildings during the Twelfth Five-Year Plan Period” (hereinafter referred to as “Planning”). As an important part of Beijing's "Twelfth Five-Year Plan" planning system, the "Planning" summarizes the achievements and experience of Beijing's building energy conservation during the "11th Five-Year Plan" period, points out the existing deficiencies, and proposes that the building energy conservation in the next five years Development goals, key tasks and safeguards.

Beijing released the energy conservation plan for civilian buildings during the 12th Five-Year Plan period. It will play a positive role in demonstration and use in September. The Beijing Municipal Construction and Development Commission and the National Development and Reform Commission issued the “Energy Conservation Plan for Civil Buildings in the 12th Five-Year Plan” period in Beijing. The plan is clear. During the 12th Five-Year Plan period, the 75% energy-saving design standard will be implemented first, which means that the annual heating energy consumption per square meter of building can be reduced by 2.65 kg of standard coal. By 2016, Beijing will have 30 million square meters of residential buildings and 30 million square meters of public buildings to carry out energy-saving reforms, which will save about 606,000 tons of standard coal. In addition, Beijing will also save 569,400 tons of standard coal through renewable energy building applications, of which: there will be 18 million square meters of civil buildings to adopt shallow geothermal or sewage source heat pump heating and cooling, and save 140,000 tons standard. We analyze that this plan's requirements for building energy conservation are clear and specific, and will play a positive role in driving other northern provinces and cities to implement their respective building energy conservation policies.

Relying on Tianjin as the North Building Energy Efficiency Demonstration Platform, the Tianjin City Development Master Plan has clearly put forward the principles of resource conservation and environmental protection, and established the overall goal of building an ecological city and energy conservation and emission reduction. In 2011, the company signed a sewage source heat pump implementation contract in Lingang and Ninghe, Tianjin, with a total contract value of 1.04 billion yuan and a total area of ​​9.39 million square meters. The company will rely on Tianjin as a renewable energy heating and cooling system project. The platform is of great significance for radiating northern cities.

Water source heat pump unit selected in the list of national affordable housing purchases Good sewage source heat pump business We maintain our opinion on the company's sewage source heat pump business. It is expected that the revenue of the sewage source heat pump business will exceed 250 million yuan, the revenue contribution will be 5%, and the performance contribution will be 13%. Annual performance of 0.07 yuan. The water source heat pump unit was selected into the national list of affordable housing purchases, marking the company's strategic layout in the sewage source heat pump business further.
