Abstract

The invention relates to a water energy storage system using a fire pool. The water energy storage system comprises air cooled heat pump cold and heat storage equipment and water cooled heat pump cold and heat storage equipment. The air cooled heat pump cold and heat storage equipment comprises the fire pool, an air cooled heat pump unit and a heat exchanger, the heat exchanger is arranged in the fire pool, and a first circulation loop is formed between the air cooled heat pump unit and the heat exchanger so as to cool fire water in the fire pool for cold storage or heat the fire water in the fire pool for heat storage. The water cooled heat pump cold and heat storage equipment comprises an energy storage tank, a water cooled heat pump unit and a cooling tower, and a second circulation loop is formed between the water cooled heat pump unit and the energy storage tank so as to cool water in the energy storage tank for cold storage or heat water in the energy storage tank for heat storage. A third circulation loop is formed between the water cooled heat pump unit and the fire pool, so that heat released by the fire water in the fire pool is used for heating the water in the energy storage tank for heat storage. A fourth circulation loop is formed between the water cooled heat pump unit and the cooling tower, so that cold released by cooling water in the cooling tower is used for cooling the water in the energy storage tank for cold storage. Therefore, the fire pool is used for carrying out cold storage and heat storage at the same time, and the cold and heat storage efficiency is high.

Description

technical field [0001] The invention relates to the technical field of water energy storage, in particular to a water energy storage system utilizing a fire-fighting pool. Background technique [0002] The water energy storage system is an energy storage air conditioning system that uses the sensible heat of water to store cold and heat. The water energy storage system includes two parts: water cold storage and water heat storage. Among them, water storage is mainly used for cooling in summer; water heat storage is mainly used for heating in winter. The water-storage air-conditioning system has the characteristics of saving the operating cost of the air-conditioning system, balancing the load of the power grid, and being energy-saving and environmentally friendly. The advantages of the water energy storage system are: simple structure, stable operation, high cold storage efficiency, fast cooling and heat release, and good load followability. The disadvantages of the water...
