Technical aspects (1) Traditional air-conditioning systems, whether water-cooled or air-cooled, have a negative impact on the building's appearance and the appearance of the building due to the heat exchanger that it must be exposed to the air, The heat exchanger buried in the ground, and away from the main building, it will not have an impact on the shape. (2) The impact of ordinary air-conditioning on the environment is very serious. It not only causes serious damage to the ozone layer and produces unpleasant noise, but also emits waste heat into the atmosphere in summer and absorbs the heat in the atmosphere in winter to make the atmosphere, Residential environment around the more harsh; and ground-source heat pump can make use of the earth's heat storage capacity, the excess summer heat into the earth access in winter, the winter extra cold energy in the summer access, in order to achieve indoor winter and summer Heating and cooling. At the same time, the operation of the device is almost free of emissions and waste, so that it has no influence on the atmosphere and can prevent the earth from overcooling and overheating. (3) Air-cooled heat exchangers and water-cooled heat exchangers heat the environment are the atmosphere, it is inevitably affected by changes in environmental conditions, will significantly reduce the heat transfer efficiency; and ground source heat pump heat exchanger and earth exchange Heat, heat transfer object is less than 1m of the formation, the initial temperature is about equal to the annual average temperature, the basic unaffected by the external environment. This temperature characteristic makes ground-source heat pumps operate 40% to 60% more efficiently than traditional air conditioners. Economic aspects (1) There are many factors affecting the economical efficiency of ground source heat pumps, such as national energy policies, environmental policies, electricity and fuel prices, the built environment, users and weather conditions. According to the current situation in our country, the operating expenses due to these factors have yet to be further studied and it is difficult to obtain accurate conclusions. However, we can learn from the experience of developed countries such as the United States. In a report on the future of air conditioning, the World Environmental Protection Organization Concluded that: Design and installation of a good ground-source heat pump, can save 30% to 40% or even more heating and cooling air-conditioning comprehensive operating costs. (2) Due to technical advantages, you can save operating costs 40% to 60%. (3) ground source heat pump system can also set heating, air conditioning and cooling and provide hot water in one. - Set of heat pump system can replace the original heating boilers, refrigeration and air conditioning and hot water heating three sets of devices or systems, thereby increasing the economy. It can be concluded that although ground-source heat pump system is more complex because of the outdoor part, the initial investment higher than the average air-conditioning system, but the operating costs of ordinary air conditioning is much higher than the ground-source heat pump system, Initial investment recovery. The use of ordinary air-conditioning life expectancy is generally about 15 years, and ground-source heat pump underground heat exchanger due to the use of high-strength inert material, buried life of at least 50 years. Therefore, from the service life and operating costs to consider, the economy of ground source heat pump system is higher than the average air conditioning system.
