一种基于排取热量平衡的地源热泵系统设计方法

地源热泵空调系统作为一种高效节能的空调系统,正得到日益广泛的应用.然而,由于建筑物的冷负荷及其运行时间往往大于供暖负荷及其运行时间,设计过程中往往取最不利情况下的负荷计算结果作为设计依据,排取热量的不平衡导致地温变化,最终影响空调运行性能.针对于此,提出了一种基于排取热量平衡的地源热泵系统设计方法.

Design method of ground-source heat pump systems based on heat balance

As an efficient air-conditioning system, ground-source heat pump systems have found wide application. Because of the difference between the cooling load and the heat load of the air-conditioning system and the difference of running duration, the load calculation of the most unfavorable conditions was used as the basis for system design. But unbalanced heat have caused the rising in temperature of the soil around the heat exchanger, and had an effect on the performance of the air-conditioning finally. Therefore, a design method of ground-source heat pump was proposed based on heat balance.
