During the heating period in 2007, 10 heating companies in Shenyang will adopt ground-source heat pump, a new heating method, in the qualified areas. Recently, Shenyang Municipal Ground Source Heat Pump Planning and Construction Management Office learned of the news. At the same time, as the energy-saving technology that is fully promoted in Shenyang City, the ground source heat pump has obviously conserved its true colors. In 2007, the installation cost per square meter was reduced by 30%. Energy saving and environmental protection are one of the topics of fashion at present. The popularization and application of ground source heat pump came into being at this time. On September 4, Wang Xinbei, a full-time deputy director of the Planning and Construction Management Office of Ground Source Heat Pump in Shenyang, revealed that with the popularity of ground source heat pumps in the market, the current market price of ground source heat pump equipment in Shenyang has been reduced by 20-30% . [Reporter experienced] ground source heat pump "a machine three energy" At present, Shenyang City, application of ground source heat pump residential quarters is still relatively small, but the response after the application is very good, the Golden Sea Park is one of them. Jinhai Park District is located in Hunnan New District of Shenyang City, close to the Hun River, is a newly developed district. Reporters fortunate enough to witness the "real brand air conditioning," the true colors. Garage Park in Gimhae side of the plot, the reporter opened the thick iron gate into the 1000 square meters of "room", saw the "machine room" within the dense pipe, a pump is pumping groundwater, and recharge wells in turn will be After the extraction of heat a fraction of groundwater irrigation back underground. This is the ground source heat pump. According to reports, this set of equipment "a machine three energy" - heating, cooling, providing hot water. So, ground source heat pump in the end what is the difference in refrigeration it? Reporters walked into the residents home to find out. Grandpa Sun is the "old resident" of Jinhai Garden and claimed to be a "conservative person", but Sun Dae-yeh holds a positive attitude toward this new thing about ground source heat pumps. Reporter Sun Grandpa home to see that each room has a similar to the central air-conditioning windows, but did not listen to the general central air conditioning noise. "Very quiet." Uncle Sun said that the general air conditioning is a bit static, but ground-source heat pump but no sound, this advantage is particularly evident when sleeping at night. Ground source heat pump technology is not limited to refrigeration, heating is good enough, Northeastern University swimming pool is the use of ground source heat pump. Xu Guangjuan, director of the Infrastructure Department of Northeastern University, introduced the building area of ​​the swimming pool of Northeast University with a building area of ​​6,775 square meters and a height of 20.49 meters with a cost of 38 million yuan. The swimming pool is unique in that it has a ground-floor heat pump system underground that provides full heating, heating, cooling, air conditioning and showering. All ground source heat pump system to support such a large-scale energy consumption, thermal equipment in the country is rare. Ground source heat pump room, the reporter saw seven ground source heat pump in quiet operation. According to reports, of which three are heated pool water and shower water, the other four are used in winter heating and summer air conditioning. "Since the use of the swimming pool and bathing water temperature is very well maintained, the winter heating temperature can reach 32 ℃; water 100% recharge, no water into the sewer due to blockage, resulting in waste of water resources; after monitoring by the relevant department did not happen Mechanical pollution and surface thermal pollution; due to the cross-use of pumping wells and recharging wells, there is no migration of sand and washing wells due to non-recharge problems. "Shenyang City Ground Source Heat Pump Planning and Construction Management Office, Deputy Director Wang Xinbei said the source The heat pump system is a new type of energy utilization technology that uses sub-floor heating and cooling to clean, efficiently and also save energy. It is estimated that if the Shenyang 10 million square meters of buildings using the technology, a heating period can save 560,000 tons of standard coal, emissions of 7.5 billion cubic meters of flue gas, more than 10,000 tons of sulfur dioxide and more than 20,000 tons Particles also disappear, such as picking off more than 100 coal-fired boiler room. The same is the consumption of electricity, "ground source heat pump" effect, equivalent to three or four air conditioners. [Billing] Ground source heat pump "Save money" In the first source of heat pump benefits so much, then it compared with the traditional air conditioning which one is better and what is weak? Statistics show that the emerging ground-source heat pump central air-conditioning system on the market today, compared with the traditional central air-conditioning, energy-saving up to 30% -50%, and will not cause pollution to the natural environment, is the most energy-saving environmental protection on the market Central air conditioning products. The survey shows that the traditional central air-conditioning is one of the major energy consumers, with energy waste and prominent environmental pollution. Taking Chongqing and Shanghai as examples only, the central air-conditioning power consumption accounts for 23% and 31.1% of the total electricity consumption of the city respectively. At the same time, The traditional gas and fuel air conditioners have large initial investment and high operation cost, and pose threats to nature and living environment due to their own technical defects. Energy-saving than air-conditioning, then how about heating? In this regard, the municipal heat pump planning and construction management office to reporters calculations, with the cost of groundwater heating costs a heating season at about 16 yuan per square meter, and Shenyang city heating prices have now exceeded the per square M 20 yuan mark, while in Harbin, a heating season heating prices have been close to 30 yuan per square meter. With groundwater heating equipment costs, 3 years will be able to "save" back. Similarly, the Affiliated Stomatological Hospital of China Medical University as early as five years ago have tasted the benefits of ground-source heat pump heating and cooling. The hospital installed two ground source heat pump units, usually start a unit in winter, to three or nine days before starting two. Automatic heating and cooling temperature control, heating and cooling costs 800,000 per year, saving more than 1/3. At present, the market price of ground source heat pump equipment in Shenyang has been reduced by 20% -30% on average. To build mid-range level of ground source heat pump system, for example, the market price from September 2006 before 180 yuan / square meter, down to the current 120-130 yuan / square meter. [Development] ground source heat pump to overturn the traditional heating Shenyang City Ground Source Heat Pump Planning and Construction Management Office Director Wang Xinbei told reporters that is expected to October 31, 2007 when the heating period is approaching, there will be 10 heating companies in the conditions of the region to adopt Ground source heat pump this new way of heating. The city's ground source heat pump technology application area will reach 18 million square meters, will be able to achieve this heating period to save 318,800 tons of standard coal, to reduce emissions of 140,300 tons of carbon dioxide, sulfur dioxide emissions to reduce 6400 tons, 4800 tons of emissions and reduce emissions to reduce emissions 82,900 tons of ash. It is expected that by 2010, the city can achieve an area of ​​65 million square meters of ground source heat pump technology, saving 1,265,000 tons of standard coal per heating period, reducing 557,000 tons of carbon dioxide emissions, reducing emissions of sulfur dioxide by 25,000 tons and reducing emission of dust and dust by 19,000 tons , Reduce emissions of 329,000 tons of ash.
