Gently press the switch, the river will flow into the "interior", the room becomes warm in winter and cool in summer. From "Yesterday (May 30, 2006)" the city's building new energy and water source heat pump technology seminar "was informed that the use of water source heat pump technology," plumbing and air-conditioning room "will be opened in Chongqing this year, next year, people are expected to stay , Air-conditioning fee will save 25%. By 2020, about 15% of the buildings in the city will use "air-conditioners."
Preferred surface water as a new energy source
Xu Yongguang, director of the city's Center for Building Technology Development, disclosed that the preferred new energy development in Chongqing is not surface water, solar energy, wind energy, but surface water, mainly using the water-heat pump technology developed by Liangjiang Water to build a water-air conditioner for the city's buildings.
Water source heat pump technology is the use of the river water temperature is relatively constant (22 ℃) features, through heat pump treatment, the introduction of indoor winter heat summer cooling. The two rivers plus more than 10 secondary rivers, water energy is also the most abundant Chongqing is also the most development of new energy sources.
Winter and summer cool air conditioning costs 1/4
At present, only 50% of Beidunan district is in Chongqing, and 95% of the buildings are high-energy-consuming buildings. Chongqing Municipality has been listed as two projects of Phase II Project of New Energy Development Demonstration City, Nan'an District Hotel and Science and Technology Entrepreneurship Development Center. This year, it will open 150,000 square meters of "water-air-conditioned" buildings. Chongqing will be divided into demonstration, industrialization, large-scale promotion of three stages of development of "water air conditioning."
Construction using heat pump technology will add some cost to normal buildings. Switch to "water air conditioning", the first is to improve the room comfort, making the room warm in winter and cool in summer. In addition, compared with the use of ordinary air-conditioning, air-conditioning costs savings of 1/4, citizens save more money.
