Chemical fiber industrial air conditioning system is composed of air valve actuator, temperature and humidity sensor, differential pressure switch, differential pressure transmitter, three-way cold water valve and actuator, steam two-way valve, frequency converter and PLC.
The basic task of the air conditioning system is to keep the air in the workshop at a certain temperature and humidity, so that the excess heat and humidity discharged from the workshop, and in time to supplement the heat and humidity is insufficient. In order to accomplish this task, to make the temperature humidity can approximate the set temperature and humidity value according to the curve of isothermal humidification, adiabatic humidification, cooling and humidification, this paper presents a design scheme of air conditioning control system composed of air system, water system and steam system.
Working principle of chemical fiber industrial air conditioning
The new air window is mainly used to bring in fresh air outside. In order to save energy, sometimes use the return air window to introduce part of the workshop return air. Fresh air Windows and return air Windows are generally equipped with regulating air doors to control the intake air volume and fresh air return ratio. The fresh air return is usually sent to the spray chamber by the fan mixed. The spray chamber has forward spray, reverse spray and multiple rows of nozzles. Deep well water and circulating water spray out fine water through the nozzle, and then reverse jet air through circulating water to complete the adiabatic humidification process, and the cooling and humidification process can be completed after water forward jet in deep well. After the air is treated by water, the regulating valve can be controlled, and the air is isothermal humidification with steam, or the air is heated by the heater. The spray chamber is used to treat the air, so that the relative humidity of the air is more stable, which is conducive to the adjustment and control of the relative humidity of the air in the workshop, so as to meet the higher requirements of the relative humidity of the air in the textile process. At the same time, treating the air with water can also play the role of cleaning the air, which is conducive to reducing the concentration of dust in the workshop air. In addition, the use of heaters can achieve rapid winter temperature rise.
