地埋管地源热泵水系统的若干问题研究

摘要

In accordance with the forms and characteristics of water system of ground coupled heat pump system in practical engineering, this paper analysis the existent problems of water system, such as valve structural failures, design mistakes and so on. Discusses design problem of water system of the ground coupled heat pump system, and then pointed out some engineering problems in water system and propose solutions thinking;Analyses the reason of failures and fault effect in water system according to the example of some projects;Furthermore, a scientific running management and optimal design method of the water resource heat pump house is proposed in order to realize energy-saving to the greatest degree.%结合调研测试的实际工程，根据实际工程中地埋管地源热泵系统中水系统的形式及特点，归纳了设计、运行管理、设备故障等几个方面的水系统常见的问题。探讨了地埋管地源热泵水系统的设计问题，指出某些工程水系统存在的问题及解决思路；分析水系统故障的原因及表现，通过对水系统运行状态的观察与测试，从机组COP及系统能效比的角度分析水系统故障的影响；对于运行管理方面，提出相应的水系统形式的运行建议，为优化地埋管地源热泵的设计及运行管理提供了相应参考。
