Due to higher heating costs, over the years heating fee collection has become a dilemma. Relevant experts have suggested that using ground-source heat pump technology in conditions-based areas of our country will save energy, help environmental protection and reduce the cost of heating. According to Zhang Kanghou, secretary general of Daqing Expert Advisory Committee of China's township and village enterprises, the principle of ground-source heat pump technology is very simple. The principle is to utilize the heat exchange coil buried deep in the ground for heat exchange with the soil. In winter, heat pump units and underground coils Get the heat in the soil for indoor heating, the summer indoor heat into the soil, to achieve the purpose of regulating the indoor temperature. Because the deep soil in all parts is warm in winter and cool in summer, the temperature change is relatively stable, which can ensure the normal operation of the ground source heat pump system. He said that compared with central air-conditioners, heat pollution and noise pollution are reduced and emissions of waste gas, waste water and waste are not discharged to the outside world. Therefore, the project is more environmentally friendly and energy-saving. Zhang Kang Hou believes that the ground-source heat pump underground coil covers an area of ​​relatively large, it is not appropriate to promote the crowded areas in the building, its suitable area should be such a vast area north of the vast areas.
