[0002] At present, the heat source for centralized heating in northern my country's cities in winter mainly relies on coal-fired, gas-fired boilers and cogeneration power plants. In order to achieve the "dual carbon" goal, it is urgent to change the heating method to reduce dependence on fossil energy. Among them, storing industrial waste heat or natural heat energy (such as solar energy, air energy, etc.) in the non-heating season through long-term heat storage and using it for heating in winter is an effective way.

[0003] Due to the advantages of environmental protection, low price and easy availability, large-volume deep pit hot water storage tanks with water as the medium are a major way of long-term heat storage. Specifically, in the non-heating season, heat exchangers, heat pumps and other equipment are used to collect industrial waste heat from power generation, smelting, chemical industry or natural heat energy such as solar energy and air energy to heat the water in the pool to about 90°C; in the heating season, heat exchangers, heat pumps and other equipment are used to release heat and cool the water in the pool, and the heat energy generated by the heat release of water can be used for heating. This deep pit hot water storage tank has been used to a certain extent. However, due to the low heat storage density of water, the volume and floor space of long-term hot water storage tanks are generally very large; secondly, since heat is not suitable for long-distance transportation, hot water storage tanks should be built close to urban heat load areas, but close to urban heat load areas, land is often expensive, so the site selection and land use of hot water storage tanks are also one of the main bottlenecks affecting the implementation of long-term heat storage projects.

[0023] The hot water storage pool of the present embodiment comprises a pool body, and the pool body can be arranged in a deep pit according to the prior art, that is, the hot water storage pool of the present embodiment is a deep pit type pool.

[0024] In this embodiment, a thermal insulation layer is provided in the middle of the pool body.
