Along with the expansion of the application field of the air conditioner, dangerous places with more explosive gases exist, the requirement on the required process environment humidity is higher and higher, and along with the increase of the building scale, the application of a centralized air conditioning system is more common, however, in a transition season, the operating efficiency of the centralized air conditioning system is lower, and in order to save energy, a mode of operating with all fresh air in the transition season is often adopted. When the fresh air runs, the air-conditioning chilled water system stops running, the air-conditioning unit is not cooled, the air-conditioning unit cannot carry out heat and humidity treatment on the outdoor fresh air, and the air-conditioning unit directly sends the outdoor fresh air into the room.
Due to the transition season, particularly the 'return-to-south' season of spring and summer in southern areas and the 'yellow plum' season in Yangtze river watershed, outdoor air has high humidity, and when the air conditioning system runs in full fresh air, dehumidification cannot be performed due to the fact that no chilled water is supplied, and humid outdoor air is directly fed into a room, so that a severe humid environment is formed indoors, the life and the working quality of indoor personnel are seriously affected, and indoor articles are likely to become mildewed and bad. In addition, even if the water chiller is started to supply cold water to the air conditioning unit for dehumidification in a transition season, the air conditioning unit in the south area generally does not have a reheating function, the air supply temperature of the dehumidified air conditioner is low, but the outdoor temperature is originally low in the transition season, no cold load exists in the room, and the dehumidified cold air is supplied into the room, so that the indoor temperature is too low, and the thermal comfort in the room is affected.
