A laboratory for the control of positive and negative air pressure in ship cabins

Abstract

The invention relates to a laboratory for the state control of air positive and negative pressure in ship cabins, comprising three functional partitions and five systems; the five systems are respectively an air supply system, an air exhaust system, a return air system, Control system and differential pressure monitoring system. The three functional divisions are control room, equipment room and air experiment area. The air experiment area is the area for controlling the state of indoor air positive and negative pressure. It is divided into four sub-physical divisions, namely: Corridor areas, buffer zones, potentially contaminated areas and core areas. The invention establishes a laboratory for the control of the air positive pressure and negative pressure state of the ship cabin. Through the experiment of the air positive pressure and negative pressure state control carried out in the laboratory, the empirical parameters are obtained, which can be used as a positive pressure protection room and a Data reference for the construction of the negative pressure isolation room; a return air system is set up in the air test area, so that the directional airflow between the sub-physical sub-divisions flows passively under the action of the pressure difference gradient, which simplifies the complexity of the system and improves the operating efficiency of the system.

Description

technical field [0001] The invention relates to a laboratory, in particular to a laboratory used for state control of air positive and negative pressure in ship cabins. Background technique [0002] The positive pressure protection room and the negative pressure isolation room can be collectively referred to as the epidemic prevention room. Different pressure differences are mainly formed by air flow in the epidemic prevention room. Due to the different air times, it is necessary to establish a laboratory for the control of positive and negative air pressure in ship cabins. During the experiment, different experimental data are obtained to provide reference for the construction of epidemic prevention rooms of different sizes. [0003] In addition, the laboratory used for the control of positive and negative air pressure in ship cabins should have different physical partitions. Regardless of whether the laboratory is in a positive pressure state or a negative pressure state, ...

AI Technical Summary

Problems solved by technology

The existing adjustment method is to install variable frequency fans at the air inlets and exhaust outlets of each physical partition, and adjust the air volume of the air inlets and exhaust outlets through the main control unit to adjust the directional air flow of the air inlets and exhaust outlets. The disadvantage of this method is that as the number of physical partitions increases, the number of fans that the main control unit needs to control increases accordingly, which increases the complexity of the system and reduces the debugging efficiency.
