Therefore, in consideration of their electrical stability, mechanical robustness, aesthetics, and smooth maintenance aspects, there is a demand for a device designed and manufactured to fit the cold and dehumidifying reality in one device.

The present invention has been made in order to solve the above problems, the cold and dehumidification in one device, the initial operation, continuous operation, intermittent operation, including the cold and dehumidification control unit to automatically perform the cold and hot switching, small and lightweight vertical type, Multi-purpose cold / dehumidifying device of horizontal type, diagonal type, contact type, etc., the electronic device's cold temperature dehumidification system which improves reliability of parts by preventing the freezing of winter road toll system and overload vehicle and preventing heat freezing in winter and cooling summer.
