Problems solved by technology
[0003] However, the existing energy storage system cannot meet the cooling and heating load requirements of the building due to the extension of the heating or cooling operation time of the buried pipe ground source heat pump. Moreover, the heat stored in the ground cannot be effectively gathered together, making it easy to lose a large amount of heat outward, thereby reducing the energy storage and energy supply effects of the energy storage system

The invention discloses a rock-soil energy storage system. The system comprises an air source heat pump main machine, a heat source energy storage pool and a cold source energy storage pool, wherein soil heat exchangers inserted into soil are arranged in the heat source energy storage pool and the cold source energy storage pool correspondingly and distributed in an array series connection structure, the air source heat pump main machine communicates with the soil heat exchangers in the heat source energy storage pool and the cold source energy storage pool through a soil side water return pipe and a soil side water inlet pipe correspondingly, a soil source circulating water pump is arranged on the soil side water inlet pipe, and the heat source energy storage pool and the cold source energy storage pool communicate with a building through energy supply circulating pipes correspondingly to provide a heat source and a cooling medium for the building. According to the rock-soil energy storage system, heat can be uniformly stored in a soil source storage energy storage system, the stored heat is prevented from being dissipated outwards along a soil source, the stored heat can be efficiently extracted to supply energy to the building, a waste rate of the heat is reduced, and the use requirements of cold and heat loads of the building are met.
Description
technical field [0001] The invention relates to the technical field of ground source energy storage, in particular to a geotechnical energy storage system. Background technique [0002] The buried pipe ground source heat pump system is a ground source heat pump system that utilizes the closed-circuit circulation of heat in the underground rock and soil. The buried pipe forms of the buried pipe ground source heat pump mainly include horizontal buried pipes and vertical buried pipes. The advantages of the system are renewability, energy saving, no pollution, and significant economic benefits. The power consumption of ground source heat pumps with buried pipes is lower than that of air source heat pumps and electric heating. It plays an important role in the energy storage and energy supply of modern buildings. role. [0003] However, the existing energy storage system cannot meet the cooling and heating load requirements of the building due to the extension of the heating or ...
