摘要
对拥有云数据管控平台的复合式地源热泵系统的热平衡控制策略进行了研究。对使用地源热泵系统的某小区采用eQuest软件模拟建筑全年逐时负荷。在逐时负荷下,通过MATLAB软件计算机组的逐时功率并得到热泵机组的逐时释热量和吸热量,进而确定一个负荷参数值k。对于夏热冬冷地区,当系统夏季逐时负荷达到k时开启热泵机组或冷水机组,使这个基于k值的控制策略可以使地源热泵系统对岩土层的释热量和吸热量达到动态平衡的效果。在TRNSYS平台上模拟运行地源热泵系统,比较新旧热平衡控制策略的优劣。
This paper studies the thermal balance control strategy of a hybrid ground source heat pump system with a cloud data control platform.eQuest software was used to simulate the year-round hourly load of a residential area using ground source heat pump system.The hourly power is calculated by MATLAB software and a parameter value k is determined.For hot summer and cold winter areas,the heat pump unit or water cooling unit will be opened when the system’s hourly load reaches k in summer,so that the k-value based control strategy can achieve the dynamic balance of heat release and heat absorption of the ground source heat pump system to the geotechnical layer.The ground source heat pump system is simulated on TRNSYS platform,and the old and new thermal balance control strategies are compared.
