How Industrial & Commercial Dehumidifiers work

Our Industrial & Commercial Dehumidifier is a refrigerant type. The refrigerant dehumidifier is the most common type in dehumidification industry. The main principle is to lower air dew point in order to realize the dehumidification result. It is perfect to perform especially in warm, humid conditions. The performance is directly related to the difference between the air dry bulb temperature and the air dew point temperature.

Industrial & Commercial Refrigerant Dehumidifier utilizes evaporator and condenser to process the air. The moisture condensed, thus the humidity level decreased. When the humid air passes into the evaporator, the inner temperature is lower than the dew point temperature of humid air. This lead gaseous water in the air to condensed and captured to the tray, and finally drains out through the pipes. The processed air passes into the condenser, being heated and recover to the room temperature. Then the dried air is released into the room back.

This system is similar to the air-conditioning circle. When the surrounding air is dried, the dew point is lowed correspondingly. Consequently, the temperature necessary to form condensation is lowed too. When the dew point relatively lowed to a certain degree, the coil temperature needed to form condensation can easily reach sub-zero. In this status, the dehumidifying efficiency will be reduced sharply. At a certain temperature, the evaporator will start to freeze. So, defrosting of the coil becomes a necessary process. Which part will make the defrosting?  The hot refrigerant gas from the compressor will pass into the evaporator coil. During the defrost cycle, the dehumidifier process ceases to remove water from the air.

The applied temperature of our Refrigerant dehumidifiers 5℃~38℃. If the ambient temperature is relatively lower than the above, we recommend the absorption type dehumidifier that is desiccant rotor dehumidifier.

How to select a suitable Industrial & Commercial dehumidifier?

  • Size & volume of your facility to calculate the required capacity.
  • Present humidity levels and the required humidity levels you need. We always consider the base of on the worst case scenarios, also taking different climatic conditions in different season into account.
  • Required humidity levels that you need to maintain regularly. This will depend on the products being stored by you.
  • Any moisture source or temperature source is also needed to be concerned.
  • Any fresh air will transfer into the room
  • Any people will go into the facility

Based on the above data, we can calculate the required dehumidification capacity and select accordingly. In some complicated cases, we need to know more details of your facility and environment.
