Recent Status and Development in Researches on Ground-Coupled Heat Pump System
At present, development of ground-coupled heat pump technology in China has entered the stage of large-scale project application from purely theoretical stage. The key question is how to apply theory to practice efficiently. However, there are still a large number of scholars who remain in the Researches on theoretical heat transfer of buried tube heat exchanger and theoretical soil thermal equilibrium. So it is essential to know the status of ground-coupled heat pump, the pressing issues and trends in the development process. This paper revealed the development status of ground-coupled heat pump, analyzed problems combining with engineering examples and predicted the development trend reasonably. The important issues are mass demonstration and promotion, which need reasonable solutions and proven technology.
