Cleaning area ventilation system and differential pressure adjusting method

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of heating and ventilation systems, and in particular relates to a clean area ventilation system and a pressure difference adjustment method. Background technique [0002] A clean room refers to a clean room that removes pollutants such as dust particles, bacteria, and particulates within a certain space, and maintains the indoor pressure, airflow velocity, and airflow direction within a specified range. In pharmaceutical workshops, the concentration of pharmaceutical active ingredients in raw materials is very high, and inhalation of a small amount of dust will cause life-threatening, and pollutants in the external environment are easily mixed into the drug to cause denaturation and failure of active ingredients. Therefore, in order to avoid the spread of harmful substances and To prevent drug contamination, the pharmaceutical workshop needs to set up clean rooms and ensure that the operating parameters in ...
