Optimization Design of Ground Source Heat Pump System of Single U Type Buried Pipe

摘要：

　　This paper is based on the new energy reform project of Southwest University of Science and Technology, according to the requirements of relevant technical specifications, test the heat exchanger tube of single U type buried pipe.A 3D numerical simulation model is established and the actual size is exactly the same.after verification by numerical simulation model, dynamic simulation of buried tube heat transfer process of heat exchanger.Study on inlet water temperature and velocity, drilling depth affect the heat transfer performance of heat exchanger of U type buried tube.It should be considered comprehensively when designing the inlet water temperature, and the circulating flow velocity is appropriate for 0.4~0.8m/s, also the drilling depth of 60~100m is more reasonable.

关键词： single U type buried pipe inlet temperature flow velocity drilling depth
