Direct Use

A groundwater heat pump (GWHP) is one type of ground source heat pump (GSHP) and is a major form of earth energy utilization, which can realize the direct use of groundwater energy or the reuse of stored underground energy. The energy conservation effect of GWHP plays an important role in the national energy strategy, but the groundwater environment has been affected and even damaged to some extent because of over-exploitation and unreasonable utilization. This paper reviews the development and challenges of GWHP in China and surveys the situation of groundwater utilization, which shows that lack of cognitive ability, scientific constraints and reasonable utilization may bring catastrophic damage to the groundwater. A coming work should aim to more researching basic problems, such as thermal interaction, energy transport in the well field, groundwater contamination, etc. In fact, the characteristics of unsteady and transient heat transfer in the complex underground environment, and their control strategies have been being also the most pressing problem. Their explorations and studies will strengthen the theoretical and practical understanding, and guide an orderly, healthy and sustainable development of GWHP.

Constant geothermal temperature is necessary to the long-term efficient operation of the ground source heat pump. SGSHP (Solar-Ground Source Heat Pump) system adopts solar energy as assistant heat source to maintain the geothermal temperature in cold regions. A design method based on equilibrium geothermal temperature was illustrated with an example of a villa in Beijing, China. Flowchart and control strategy of the combined system were introduced. Average heat collection efficiency and necessary area of the solar collector were derived on the basis of energy balance equation. Geothermal temperature variation was also researched to test if the solar energy and geothermal energy were reasonably matched. Results show that the combined system can maintain a constant geothermal temperature if it is well designed. The solar-ground source heat pump system is efficient, reliable and energy-saving.
