Buried underground heat pump central air conditioning to create energy-efficient housing

No boiler room in winter, no cooling tower in summer, a direct use of underground soil temperature and seasonal temperature difference between the ground space conversion, air conditioning and heating and heating for the new technology has now been widely used in the Binhai New Area.

Experts said that this buried tube ground source heat pump technology not only has the advantages of environmental protection, energy conservation, economic advantages and monitoring by the state authority monitoring institutions, its energy efficiency up to 1: 4 or more than the traditional central air-conditioning energy efficiency Higher than 30%, energy saving effect in more than 50%. If 100 million square meters of buildings using this technology, each year can save 11,900 tons of standard coal, reduce emissions of 130 million cubic meters, saving nearly 100 million yuan in investment, annual operating cost savings of about 10 million yuan, but also a lot of savings in facilities Land.

In a printing enterprise located in Airport Logistics Processing Zone, the traditional boiler room and cooling tower can not be seen in the factory area of ​​more than 20,000 square meters. The temperature in office buildings, factories and warehouses is very comfortable. According to Tianjin Cold Technology Company's technical staff, the plant's heating and cooling facilities are not on the ground, the heat exchanger buried deep in the ground 100 meters. Underground soil is rich in temperature resources, the average temperature can reach 16 degrees Celsius, the summer underground soil temperature below the temperature above the ground, winter soil temperature below the ground above the ground temperature. Ground source heat pump technology is the use of this seasonal temperature difference, through special devices in the summer will be the transformation of low-temperature underground soil resources to the ground space for cooling in winter will be the underground soil heat resources to heat transfer to the ground space. The Buried ground source heat pump is more direct, it buried in the heat exchanger in the soil, the pipe has a closed water cycle and soil heat exchange, winter soil heat absorption, summer release of heat to the soil for storage, etc. Reuse in winter will not have any impact on groundwater resources. The central air-conditioners manufactured by this technology are non-fuel oil, non-combustible gas and non-combustible coal. They can be flexibly controlled according to needs. The switch is self-ventilated. Generally, the indoor temperature in winter can reach 26 degrees Celsius and the indoor temperature in summer reaches 22 degrees Celsius.

Buried ground source heat pump central air-conditioning system's technical characteristics are "to the earth to be cold and heat source." It is understood that the successful application of Tianjin Bonded Holdings Building, Huiyuan Printing Co., Ltd., Toray foreign storage and transportation companies, Manor Man King Manor and other 20 projects, and achieved good social and economic benefits.
