Problems solved by technology

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

Abstract

The present application discloses a cooling system capable of energy storage and an adjustment method thereof. The cooling system comprises a ventilation device, a heat medium distribution system, a heat dissipation system, a cooling medium acquisition system, and at least one medium storage tank. The medium distribution system comprises multiple water distribution branch pipes connected in parallel to each other and connected to the heat dissipation system. In spring, summer, and autumn, a favorable nighttime cooling condition is used, and flow in a medium pump is increased. A heat medium is cooled by leveraging a system cooling capacity margin in an environmental condition, such that the temperature of the medium in the system gradually drops as a whole, so as to cause the temperature of the medium in the medium storage tank to gradually drop; thereby performing cold storage. When the temperature of a low temperature end of the heat dissipation system is too low, the flow in the medium pump is gradually increased so as to heat the heat dissipation system by using the medium stored in the medium storage tank. The present application allows for easy adjustment, a safe and reliable system, and achieves high average thermal efficiency.

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...
