What is fresh air dehumidifier

After the fresh air dehumidifier dehumidifies the outdoor air, the relatively dry air that reaches the target relative humidity is sent indoors through the fresh air duct to meet the humidity requirements of the comfortable or technological indoor environment. The dehumidified air is generally used in indoor places where air purification is required

Fresh air dehumidifier application

Fresh air dehumidifiers, in many occasions, require high fresh air volume, and some directly require a fresh air supply system. Fresh air supply puts forward high requirements on the temperature and humidity treatment. The central air-conditioning system simply cannot solve the temperature and humidity at the same time. The problem. Some reduce the outlet air temperature, and then use electric heating to increase the temperature to reduce the relative humidity. This method can be used in an environment where the fresh air volume is very low, but it is also very energy-intensive. Nor is it a desirable method. If it is a fresh air system, it can hardly meet the requirements. Assuming that the cold air outlet temperature is 18 degrees, the relative humidity is higher than 95% at this time, and the temperature is increased to 23 degrees, and the relative humidity should be above 70%. Therefore, independent development of air handling units for fresh air is necessary. After years of industry practice, it can solve the fresh air treatment requirements of different process requirements, mainly supporting the independent pipeline dehumidification section of the central air-conditioning system. For the duct ventilation dehumidification unit of the fresh air ventilator, a fresh air multi-stage processing air conditioning unit has been developed for the space with temperature requirements.

The particularity of fresh air dehumidifier

The fresh air dehumidifier dehumidifies the outdoor air once, while the ordinary dehumidifier placed indoors is a cyclic and progressive dehumidification. Therefore, if the target humidity of the two is the same, the difference in moisture content per unit time of the former is much larger than that of the latter. Therefore, when calculating the wet load, the "one-time" dehumidification capacity of the fresh air dehumidifier should be fully considered. Compared with the confined space circulating dehumidifier, the initial humidity of the fresh air dehumidifier that only treats outdoor air once is always the constant relative humidity of the current outdoor atmosphere, so it is necessary to accurately calculate the dehumidification amount of the fresh air dehumidifier before optional Type in order to achieve the purpose of controlling the target humidity.

Selection of fresh air dehumidifier

The fresh air dehumidifier, based on the dehumidifier manufacturer of Guangdong Nesta, mainly calculates the key values such as the total refrigeration of the dehumidifier and the dehumidification capacity per unit time based on the air flow quality per unit time, the difference in moisture content, and the difference in welding value. Optional; selection of fresh air temperature and dehumidifier, and configuration after calculating its overall cooling/heating load.
