The invention belongs to the technical field of heating and ventilation systems, and particularly relates to a cleaning area ventilation
system and a
differential pressure adjusting method. The cleaning area ventilation
system comprises a plurality of first partition plates, a plurality of second partition plates, a plurality of
air treatment units, a plurality of air conveying valves and a plurality of air inlet valves, a cleaning area is divided into a plurality of partitions by the first partition plates, each partition is divided into a plurality of cleaning chambers by the second partition plates, each cleaning chamber is provided with an air inlet and an air outlet, the
air treatment units are in one-to-one correspondence to the partitions, each
air treatment unit comprises an
air conditioning unit, an air conveying pipeline and an air returning pipeline, the air conveying valves are in one-to-one correspondence to the air treatment units, each air conveying valve is used for controlling the air amount conveyed by the
air conditioning unit into the air conveying pipelines, the air inlet valves are in one-to-one correspondence to the cleaning chambers, and each air inlet valveis used for controlling air amount conveyed by the air conveying pipeline into the cleaning chambers. The cleaning area ventilation
system conveniently adjusts
differential pressure of the cleaning chambers, time and labor are saved, and production efficiency is improved.
