ABSTRACT
In the cooling-dominated area, the long-time operation of the ground source heat pump will disrupt the underground heat balance, resulting in the deterioration of system performance. The coupling of auxiliary cooling devices and ground source heat pump systems can effectively alleviate the problem of underground heat imbalance and reduce the initial investment. This paper expounds on the types, connection modes, dimensions, and operating parameters of auxiliary cooling devices, as well as the design and research of each part, and points out the current problems and future development direction according to the whole system.
