冷却塔辅助排热的复合地源热泵系统及其运行控制

摘要

The ground source heat pump heating system is the main form of application of renewable energy source in energy saving building. In view of the fact that the air-conditioning load is much more than heating load in the southern region of China, the hybrid ground source heat pump system and its running control strategy with cooling tower as aided heat dissipation system are presented in this paper. Furthermore, a design example and its detailed control strategy of this hybrid ground source heat pump system are given. All results in this paper can provide some reference values for the engineering design.%地源热泵空调采暖是建筑应用可再生能源的一种主要形式。针对我国南方地区夏季空调负荷远大于冬季供暖负荷的特点，介绍了采用冷却塔作为辅助排热的复合地源热泵系统，以及这种复合系统的实际运行控制策略。给出了一个关于这种复合地源热泵系统的设计实例及其具体控制策略，内容可供相关工程设计参考。
