Abstract

As a type of groundwater heat pump, single-well groundwater heat pump systems have received much attention in recent years due to its efficient properties. In this chapter, a sand tank experiment system of single-well systems is designed and set up in Harbin Institute of Technology. The aim of this study is to find the relationship among the temperature of outlet water, the power of the single-well systems, the thermal transfixion, and the distance between pumping screen and injection screen. The data obtained demonstrate that the mean temperature of outlet water and the power are increased, and the coefficient of thermal transfixion is decreased when the distance between pumping screen and injection screen is raised. The distance between pumping screen and injection screen is an important factor in the single-well systems that can affect the power of the system directly. The coefficient of thermal transfixion is an appropriate parameter to evaluate the single-well systems.
