Abstract

The invention discloses a cooling system with an energy storage function and an adjusting method thereof. The cooling system comprises a ventilation device, a heat medium distribution system, a heat dissipation system, a cooling medium collecting system and at least one medium storage tank and the like, wherein the medium distribution system comprises a plurality of water distribution branch pipelines, and the water distribution branch pipelines are connected with the heat dissipation system in parallel. The adjusting method is characterized in that in three seasons of spring, summer and autumn, the flow of a medium pump is increased as far as possible by utilizing relatively good cooling conditions at night, and the allowance of the cooling capacity of the system under the environment condition is fully utilized for cooling heat media, so that the medium temperature of the system is gradually reduced, then the temperature of media in the medium storage tank is gradually reduced, and the cold storage effect is achieved; and when the temperature of a low-temperature end of the heat dissipation system is too low, the flow of the medium pump is gradually increased, so that the heat dissipation system is heated by utilizing the media stored in the medium storage tank. The cooling system with the energy storage function and the adjusting method thereof have the advantages of being convenient to adjust, safe and reliable in system, high in average heat efficiency and the like.

Description

technical field [0001] The invention relates to an energy storage cooling system and an adjustment method thereof, belonging to the field of energy storage and utilization. Background technique [0002] The circulating water cooling system involves the cold end system of the power plant, which is a necessary condition for establishing the vacuum of the steam turbine and taking away the heat source of the cold end. However, affected by changes in ambient temperature, most of the units face insufficient output when the temperature is high in summer, and are forced to operate in a state of high back pressure and high energy consumption in winter due to safety requirements such as antifreeze (surface-type circulating cooling units). It has brought great challenges to the economy, safety, stable operation and load response of the unit. Contents of the invention [0003] The object of the present invention is to provide an energy storage cooling system and its adjustment method...
