The working principle of the Air Conditioner which consists of the process of using a refiner using a dry type evaporator, which results in the evaporator cooling will be sent by the fan into the room so that it becomes cold. By changing the evaporator into a crystal or ice tube mold, the conversion process will no longer be distributed indoors, but will be focused on the crystalline or ice tube molds. With a system that regulates using smart relays, it is hoped the freezing and thawing processes can be faster and more optimal
