地温中央空调是一种新型节能空调设备，它根据可逆卡诺循环原理，利用地温能源，冬天采用热泵技术原理，通过热交换将地下水或土壤中的热量提出用于室内采暖，而夏天则利用地下土壤或地下水带走热量，达到制冷效果。并可提供生活用水。地温中央空调的另一特点是环保价值。
Geothermal central air conditioning is a new type of energy-saving air conditioning equipment. According to the principle of reversible Carnot cycle, it uses geothermal energy, uses heat pump technology in winter, and puts forward the heat in groundwater or soil for indoor heating through heat exchange. In summer, it uses underground soil or groundwater to take away heat, so as to achieve refrigeration effect. It can also provide domestic water. Another characteristic of geothermal central air conditioning is its environmental value.
