Abstract

The invention relates to a control method of a ventilation system and the ventilation system using the control method. The control method comprises the steps that an exhaust air speed target value of each room is determined based on the size of each room, the set ventilation frequency and the exhaust outlet area of an exhaust pipeline; based on the exhaust air speed target value, an air supply air speed target value of each room is determined; the exhaust air speed and the air supply speed of each room are detected; the measured exhaust air speed and the measured air supply speed are compared with the corresponding exhaust air speed target value and the corresponding air supply speed target value respectively; and based on the comparison result, the rotating speed of an exhaust fan and the rotating speed of an air supply fan are controlled, the opening degree of an exhaust air valve and the opening degree of an air supply valve corresponding to each room are controlled, the exhaust air speed is larger than or equal to the exhaust air speed target value, the air supply speed is larger than or equal to the air supply speed target value, and the exhaust air speed is larger than the air supply speed. The control method of the ventilation system can be controlled based on the set ventilation frequency and the set pressure difference, and the control precision is high.

Description

technical field [0001] The invention relates to the technical field of ventilation, in particular to a control method of a ventilation system and a ventilation system. Background technique [0002] Ventilation is a control technology for exchanging the air in the room or other regulated areas by means of ventilation dilution or ventilation exclusion. In order to achieve the purpose of ventilation, a ventilation system is usually used for control. The ventilation system can be divided into three types: fresh air system, return air system and recirculation system. Among them, the fresh air system is to deliver outdoor fresh air to the room (that is, "fresh air") to meet the needs of indoor fresh air ventilation; the return air system is to combine part of the fresh air with indoor air (or called "return air") After mixing and processing, it is transported to the room; the recirculation system (or "closed system") uses return air (ie "no fresh air") to supply air to the room....
