针对国内某工程项目的地源系统冷热不平衡实际问题,对地源冷热不平衡问题及其影响进行了简单阐述,并将基于混合式地源热泵的空调控制系统应用在此工程项目中。在对控制方案进行分析和研究后,根据项目实际工况提出冷热侧及地源热泵的控制方案,最终对地源电气控制部分的设计进行了阐述。 Aiming at the actual problem of thermal imbalance in ground source system of an engineering project in China, this paper briefly explains the problem of thermal and thermal imbalance in ground source and its influence, and applies the air conditioning control system based on hybrid ground source heat pump in this project . After analyzing and researching the control scheme, the control schemes of hot and cold side and ground source heat pumps are put forward according to the actual conditions of the project, and finally the design of the control part of ground source is expounded.
