Aiming to provide technical guidelines for improving summer-spending performance of direct aircooling units

several technical schemes of improving operating performance of air-cooling units in summer was discussed.The review focuses on the application background

technical scheme and application effect.It shows that

under the condition with fixed operating parameters

the peak cooling system distributes part of steam turbine exhaust and the direct air-cooling system heat load reduces

as well as the operating backpressure.The overall heat transfer area increases by adding several air-cooling units

thus the overall heat transfer performance of the direct air-cooling system improves and the operating back-pressure decreases.For a certain direct air-cooling unit

the technical scheme should be selected according to the unit's actual situation.
