Overview

The control of the fresh air treatment system includes various interlocking contents such as supply air temperature control, supply air speed control, supply air relative humidity control, antifreeze control, CO2 concentration control, and pressure difference control between filter screens. If the fresh air unit needs to consider bearing indoor loads (such as DC units), it is also necessary to control indoor temperature (or indoor relative humidity). A fresh air treatment system is an air conditioning device that provides fresh air. Functionally, it can achieve constant temperature and humidity or simply provide fresh air according to the requirements of the usage environment. The functions of dust removal, dehumidification (or humidification), cooling (or heating) can be customized according to the needs of the usage environment. Mainly used in industries such as electronic factories, purification workshops, and pharmaceutical warehouses, it meets the automation control requirements of buildings.

Product Details

The fresh air treatment system adopts on-site controllers to systematically control the fresh air unit system. Including: supply air temperature control, supply air relative humidity control CO2Concentration control and various interlocking contents.

1. Supply air temperature control

2. Indoor temperature control

3. Relative humidity control

The main point of relative humidity control for fresh air units is to select the setting position or control parameters of the humidity sensor, which is related to its humidification source and control method.

(1) Steam humidification

(2) High pressure spray, ultrasonic humidification and electric humidification

(3) Circulating water spray humidification

(4) Carbon dioxide (CO)2）Concentration control

After processing through the controller, the opening of the inlet valve is controlled by on-site PID and other self-control algorithms to regulate the indoor temperature. The management center can control the start and stop of the fan. The function of the differential pressure switch in the air duct is to activate when the fan starts, otherwise it is judged as a fan failure. Install differential pressure switches before and after the filter screen of the fan. When the dust on the filter screen is too large, the differential pressure value increases. When it exceeds the set value, the switch will trigger an alarm and maintenance or repair can be carried out. The analog signals of the on-site controller are respectively connected to the water valve, air valve, etc., to control the opening and closing of the valves and achieve the goal of energy conservation.
