Into the city of Harbin Wangjiang Hotel or Swire Mall, always feel like spring comfort, who can think of here, heating and cooling neither oil, no electricity yet. The two businesses adopted an internationally leading new technology, which reduced the cost of heating and air conditioning systems from RMB 61 to RMB 41 per square meter before use. It also saved various fees such as sewage charges and air pollution fees. This new technology is "urban primary sewage heat energy technology and technology," and Heilongjiang Provincial Science and Technology Department organized the results of the appraisal meeting was HVAC, refrigeration, engineering thermophysical identification expert group identified. The technology overcomes the international technical problems of sewer contaminants in the sewer, in particular, domestic sewage whose content is over 1% can not be utilized because of the difficulty in regenerating the filter surface, thereby turning the city sewage into a treasure and providing heating and cooling for the building. Professor Sun Dexing, a professor at the Harbin Institute of Technology Institute of Heat Pump Air Conditioning, led his disciples to study hard for more than two years before they developed the world's first, world-leading technology. Residential or office buildings require heating in winter and air conditioning in summer. Both heating and air conditioning require large amounts of energy, especially fossil fuels, which waste resources and pollute the environment. Energy emergency, now we must promote the use of renewable energy, environmental energy, such as wind, tidal energy, solar energy, geothermal and other alternative energy sources, these environmental energy is often low energy, low temperature, unusable. In order to use these energies, a mechanical heat pump is used. Heat pumps and chillers are one and the same principle of the same kind of machinery. Heat pump has both cold and hot ends, heat pump can take heat from the low environment, and then turn it into high temperature and then sent out for people to use. The sewage temperature is high, for example, Harbin City, sewer discharge into the sewer temperature is about 100C, you can use the heat pump to extract heat from the sewage. The heat pump is electrically driven. If you consume 1 part of the energy, you can draw 3 parts of heat, plus the electrical conversion of the heat, that is, the ratio between the energy consumed and the heat gained is 1: 4. The same quality of coal, thermal power efficiency is 0.3, the average efficiency of direct combustion heating is 0.7, if the use of heat pump efficiency is 1.2, equivalent to 40% energy saving. Heat pump requires environmental heat source, unfortunately, heat source is not easy to find. In Harbin, for example, neither water source nor air source heat source, heat pump applications have been suppressed, the professionals found that due to the sewage has a large amount of large, wide temperature and temperature characteristics, so the world has long been the use of sewage treatment Water as a heat source precedent, but only treated with sewage treatment plant discharge of water for the construction of the nearby supply, a small range of applications. The technology takes advantage of sewers throughout the city - collecting water all over the place, greatly expanding the heating area. As long as there is a sewer, and sufficient sewage, you can apply this technology. The technical difficulty is that the sewer sewage has a lot of debris, the content is too high, about 1%, if the filter, the filter surface can not be renewable; if not filtered, will block the heat pump normal operation, it can not be used as a heat pump heat source . New technology to solve the problem of regeneration of the filter surface, with a relatively low investment, heat transfer can be achieved without clogging. Sewage through a special sewage treatment device, adjust the size of the mesh size of the water blocking the contaminants in the heat pump, and other heat pump to seize the heat in the sewage, the sewage through the circulating pump and other machinery will contaminate the belt Go, intact back to the sewage area, so that neither block the heat pump, do not pollute the environment. In the case of no heating in the south, we can turn the waste water into a cold source. That is, the summer to remove heat with sewage, winter waste water to take heat. The technology is non-barrier geographical, can be widely used. Its advantage is low cost, if the city's buildings are used for floor heating or fan coil can use this technology, compared with the traditional winter boiler heating network, central air conditioning system, the initial investment and operation of About 30% cost savings. Heilongjiang belongs to the old industrial base, a large proportion of heavy industry, industrial waste heat recovery should be a lot of articles to do, especially the oil industry, steel industry, printing and dyeing industry, wastewater, each will be a major issue for future research, Professor Sun Said it will continue in-depth research.
