摘　　要：提出复合式地源热泵系统的顺序控制法与湿球温度控制法,建立了基于TRNSYS的复合式地源热泵系统及其控制系统模拟平台。以郑州某建筑复合式地源热泵系统为研究对象,并对该系统在不同运行控制下的运行及能耗进行动态模拟。模拟结果表明对于该地源热泵系统,采用湿球温度控制法并选定合适的湿球温度能保持土壤的热平衡性并且减少系统能耗。This paper presents a sequence operation control strategy and a wet-bulb temperature-based control strategy for a hybrid ground-source heat pump system. A simulation platform is also developed for this heat pump system and its control system based on TRNSYS. The operation and energy consumption were dynamically simulated. The results show that ground heat balance can be kept well for this system and when the wet-bulb temperature-based control strategy with proper wet-bulb temperature set-point is used for this system.
