What's the difference between a cold dryer and a dehumidifier? It should be the same.

The dehumidification principle of cold dryer and dehumidifier is the same: cooling makes part of gaseous water in the air become liquid water to be removed, and finally reduces the moisture content in the air.

The cold dryer is used as air source treatment equipment to treat the air source;

As an environmental purification device, dehumidifier is used to treat the space environment, which is similar to the principle of air conditioning.
