New Technology for Heating and Air Conditioning

According to Professor Fang Zhaohong, an expert on ground source heat pump technology and building energy conservation, the environmental problems caused by the massive burning of fossil fuels have increasingly become the focus of attention of all governments and the public. In addition to the type of central heating, there is an urgent need to develop alternative alternative heating methods. Ground source heat pump is a new technology for heating and air conditioning that can effectively save energy, reduce air pollution and emissions of carbon dioxide and other gases.

Ground source heat pump system can be achieved on the building heating and cooling, but also for domestic hot water, a multi-purpose machine. A system can replace the original boiler plus cooler two sets of devices or systems. Compact system, eliminating the boiler room and cooling tower, saving construction space, but also conducive to the appearance of the building. Another notable feature of the ground-source heat pump system is that it greatly increases the utilization of primary energy and therefore has the advantage of being energy efficient. Ground source heat pump than the traditional air conditioning system operating efficiency of about 40-60% higher. In addition, the relatively constant temperature of the ground source makes the operation of the heat pump unit more reliable and stable. The maintenance cost of the entire system is also greatly reduced compared with the boiler-refrigerator system, which ensures the high efficiency and economy of the system. According to foreign experience, due to the low operation cost of ground-source heat pumps, the increased initial investment can be recovered within three to seven years. The average cost of the ground-source heat pump system during the entire service cycle will be lower than that of a traditional air-conditioning system. Ground source heat pump (underground heat pump system) a wide range of applications, low operating costs, energy saving and environmental benefits significantly.

Ground-source heat pump has been widely used in many countries in North America and Europe and is a mature technology. However, our country has just started the application of ground-source heat pump. Xiangtan City, Hunan Province took the lead in the successful application of the first case of the regional geothermal air-conditioning energy saving, environmental protection, low cost, safe and reliable advanced technology, which marks the application of geothermal air-conditioning technology in China has taken a big step forward. This is an environmentally friendly, energy-saving, economical, unprecedented results of heat pump technology.
