Dehumidifiers can indeed work in cold rooms, but their efficiency may be affected by the temperature.
In fact, most dehumidifiers are designed to work in temperatures between 40°F and 90°F, which is the ideal range for optimal performance.
At lower temperatures, the dehumidifier's ability to remove moisture from the air decreases, which can impact its overall effectiveness.
However, some dehumidifiers are specifically designed for use in cold rooms, such as those used in refrigeration or air conditioning systems, and can operate in temperatures as low as 32°F.
