Description
技术领域technical field

背景技术Background technique
地源热泵系统是利用浅层地能进行供热制冷的新型能源利用技术的环保能源利用系统。地源热泵系统通常是转移地下土壤中热量或者冷量到所需要的地方，还利用了地下土壤巨大的蓄热蓄冷能力，冬季地源把热量从地下土壤中转移到建筑物内，夏季再把地下的冷量转移到建筑物内，一个年度形成一个冷热循环系统，实现节能减排的功能。The ground source heat pump system is an environmentally friendly energy utilization system that utilizes shallow ground energy for heating and cooling. The ground source heat pump system usually transfers the heat or cold in the underground soil to the required place, and also utilizes the huge heat storage and cold storage capacity of the underground soil. In winter, the ground source transfers the heat from the underground soil to the building, and in summer The cooling capacity from the ground is transferred to the building, forming a cooling and heating cycle system every year, realizing the function of energy saving and emission reduction.
传统的地源热泵系统一般由室外地能换热系统、地源热泵机组和室内采暖空调末端系统。而目前常见的用于地源热泵系统的室外地能换热装置一般为高密度聚乙烯换热管，将该换热管直接埋入土壤中，通过换热管直接与土壤接触进行热量交换，但由于土壤的导热率较小，使得热量交换的速度较慢，从而容易导致热量交换的不及时，效率低。The traditional ground source heat pump system generally consists of an outdoor ground energy heat exchange system, a ground source heat pump unit and an indoor heating and air conditioning terminal system. At present, the common outdoor ground energy heat exchange devices used in ground source heat pump systems are generally high-density polyethylene heat exchange tubes. The heat exchange tubes are directly buried in the soil, and the heat exchange tubes are directly in contact with the soil for heat exchange. However, due to the low thermal conductivity of the soil, the speed of heat exchange is slow, which easily leads to untimely heat exchange and low efficiency.
