Does a wine cellar refrigeration system really control humidity?
Only if it has controls that will sense the humidity and operate a humidifier and a reheat system. Normally a wine cellar system reduces the humidity as little as possible. If the cellar humidity goes below the ideal 60 to 80% RH levels there is no way the basic system can add humidity without a humidifier. In addition, the controls must be designed for the addition of humidity. Wine Environments can provide optional humidity controls and humidifiers for those applications where the humidity is dropping below the 60 to 80% range.
