东北某图书馆土壤源热泵冬季间歇运行模式的研究

The Study on Interim Operation Mode in Winter by Ground source heat pump in a Library in Northeast China

以东北某高校图书馆为研究对象,运用Equest能耗分析软件对建筑物全年动态负荷进行数值模拟分析,并结合土壤源热泵系统长期的运行特性,将土壤源作为具有典型间歇性负荷特性的建筑物的冷热源,在冬季制热工况下,采用间歇运行的方式,给予土壤一定的温度恢复期,来减缓地下土壤温度的持续走低,更好的满足建筑物空调负荷的动态变化以及确保土壤源热泵长期、高效的运行。

The dynamic load of a building cross the year was simulated and analyzed by means of energy consumption analysis software Equest for a library in northeast China. In association with the long operation features of ground source heat pump, the ground was taken as the sources of heating and cooling for buildings with typical interim loads in winter for heating in order to allow ground to have certain time for recovery in temperature. So, the continuous drop of ground temperature would be slowed down. The long term and efficient operation of ground source heat pump were ensured to satisfy the dynamic changes of air conditioning load in buildings.
