Cabinets air conditioning (air conditioner control cabinet) work through the compression refrigeration to achieve cooling down the heat, to counter the heat and moisture transfer, with the case in confined circumstances. In the external environment the high temperature, dust, oil, corrosive gases will not enter the Internal Control, so as to solve the cooling fan brought about by a series of issues. Control cabinet can be maintained at 30 - 35 ℃ ,the proper temperature environment. The life and stability of electronics and electrical equipment have been effectively guaranteed.
