Abstract

The invention discloses a method for cooling a container energy storage system through underground water and a temperature adjusting system thereof. According to the method, an internal circulation cooling mode is adopted, specifically, underground water of a constant-temperature water layer is pumped and then fed into a hot water reservoir through a plurality of fan coils, and meanwhile the temperature adjusting system pumps air in a battery cabin; the extracted air in the cabin respectively flows through each fan coil through internal circulation air ducts to exchange heat with the underground water, and the air in the cabin is blown into the battery cabin to realize cooling; when the temperature in the battery cabin is still continuously higher than the high-temperature threshold value in the internal circulation cooling mode, the temperature adjusting system is switched into an external circulation cooling mode, the internal circulation air ducts are switched into external circulation air ducts communicated with the outside, and the external circulation air ducts suck external air, and the external air flows through each fan coil and then is blown into the battery cabin to realize cooling. Under the condition that direct refrigeration or heating is avoided in a low-temperature environment, the temperature of the energy storage system in different working states is adjusted.

Description

technical field [0001] The invention relates to a method for cooling a container energy storage system by using underground water and a temperature regulating system thereof. Background technique [0002] In recent years, under the vigorous promotion of the country and the government, renewable energy has attracted more and more attention, and the lithium-ion container energy storage system has been widely used on the user side and the power grid because of its low maintenance cost, long service life, and no pollution. side. The container used in the energy storage system is divided into a battery compartment and an equipment compartment. In the battery compartment, a plurality of lithium-ion batteries are arranged through battery racks, and monitoring equipment is arranged in the equipment compartment. However, the lithium-ion battery generates a lot of heat during operation, and it needs to be cooled in time, otherwise the life of the lithium-ion battery will be reduced. ...
