Shallow geothermal energy is stable and clean. Using a heat pump to produce groundwater and realize heating and cooling can effectively prevent haze and reduce energy consumption. To reduce engineering costs, many buildings in Beijing, China, plan to utilize single-well groundwater source heat pumps. Numerical modeling is an effective way to gain an understanding of thermal transport processes. However, wellbore-reservoir coupling and the uncertainty of productivity due to geological parameters make simulation difficult. A wellbore-reservoir-integrated fluid and heat transport model is defined by T2Well simulator to predict the productivity of a typical single-well system, with consideration of complex geological factors. The model is validated by the analytical model developed in Beijing, China. The fluid processes in the wellbore are described by 1 D non-Darcy flow, and the reservoir 3 D fluid and heat transport processes are calculated. Six crucial factors satisfying a random distribution are used, and for a single well that can supply heat for an area of 9000 m2, the output temperature during the heating season ranges from 11°C to 15°C.

Abstract There have been few practical applications of solar coupled groundwater source heat pump (GWHP) systems in large public buildings, and data on this technology are scarce. A solar coupled GWHP system was investigated in this study. The system uses an underground water source heat pump system for heating in winter, cooling in summer, and providing part of the domestic hot water, and it also uses a solar energy system to prepare domestic hot water. These two types of energy are complementary. The system was tested throughout the cooling season. This experiment ran from May 10, 2021, to September 10, 2021. The results show that the system can guarantee the indoor design temperature and the supply of domestic hot water. The solar water heating system operated for 1233 min in the summer; hot water (2334 m3) was prepared. During the summer, the average energy efficiency ratio of the GWHP unit was approximately 4.88. The energy efficiency ratio of the entire system was approximately 3.34. Such projects can play a key role in demonstrating this type of system.

The potential analysis of geothermal energy based on geothermal characteristics requires research of the regional shallow geothermal energy. Then, an evaluation model can be constructed. Taking Weinan City as an example, this paper studied the depth and temperature characteristics of the constant zone of subsurface temperature, the vertical variation characteristic of geotemperature, and the horizontal distribution characteristic of geotemperature in Weinan City. Based on the analysis of geotemperature characteristic, the analytic hierarchy process was used to construct the zoning evaluation system of the suitability of ground source, groundwater source, and surface water source. Then, the suitability of Weinan city was comprehensively zoned by the zoning evaluation system. The heat capacity and heat-exchange power of the heat pump system at the groundwater source were calculated based on the zoning results, and the heat-exchange power of the ground-coupled heat pump was obtained. According to the evaluation index, the development potential of shallow geothermal energy resources was evaluated. Through the experimental analysis, applying the model in this paper, it can be seen that the heat pump system has great potential for heating in winter and cooling in summer. The area is 50.79 km2. The area of the potential middle region of the buried pipe heat pump is 135.74 km2, and the potential of the ground source heat pump system is low. The potential area of the ground source heat pump is 82.14 km2. Upon comparing the model results with the current results, it was found that the consistency between the two is high.

The groundwater source heat pump (GWHP) system utilizes groundwater as alternative renewable and clean energy source for space heating and cooling, withdraws water from a production well, passes it through a heat exchanger and discharges the water into an injection well. Hebei Province of China is rich of geothermal resources; there are suitable hydrogeological conditions in most areas. Take an office building in Hebei Province for example; a detail loads analysis of the groundwater source heat pump system was conducted.
