土壤源热泵与蓄冷耦合系统的研究分析

Research and Analysis of Ground Source Heat Pump and Cold Storage Coupling System

随着社会经济的快速发展,能源瓶颈问题日益突出。寻找更高效的供暖空调方式刻不容缓。土壤源热泵系统自问世以来,以其高效节能的特点逐渐得到大力发展。蓄冷系统凭借“削峰填谷”的优势一直备受青睐。两系统优点存在理论上的互利共存。本文以某实际工程为例,采用DeST软件建立建筑模型,模拟全年负荷特点,并研究分析土壤源热泵与蓄冷耦合系统特性,得到如下结论:相比多联式空调系统,耦合系统全年运行费用节约40%。

With the rapid development of social economy,the problem of energy bottleneck becomes increasingly prominent.It is urgent to find more efficient heating and air conditioning system.Since its inception,ground source heat pump system has been vigorously developed with its characteristics of high efficiency and energy saving.With the advantage of"cutting peak and filling valley",the cold storage system has always been favored.The advantages of two system are complementary.Taking a practical project as an example,this paper uses DeST software to set up building model to simulate the annual load characteristics,then study analysis the characteristics of ground source heat pump combined with cool storage air conditioning system.The following conclusions are drawn:compared with multi connected air conditioning system,the annual operation cost of coupling system is reduced by 40%.
