The background of Humidity Industry

Humidity control is one of the key technologies to the modern industry and residential environment: the most comfortable ambient temperature is at about 25 ℃ and the relative humidity is during 45% ~ 55% RH. And with the appropriate relative humidity, people will feel very comfortable to keep healthy and raise working efficiency, or it can cause skin dry and itchy with the lower relative humidity; In addition, the humidity control in some factories, such as electronic factory, semiconductor plant, program machine room, explosion protection factory, textile mill, printing house, film factory etc., will be related to the production safety and product quality; some are very particular about the ambient humidity just like cigarette, refrigerator fresh-keeping, food resurgence, aging test, heritage preservation. In order to promote the new technologies and productions about humidifying and dehumidifying.
