  In the case where an evaporator and a condenser are arranged on both sides of the main body, it is necessary to arrange a water tray for processing drain water generated by the evaporator at the lower part of the evaporator, but the body shape is reduced in size. If you try to keep the depth of the water pan small, drain water will splash on the floor inside or outside the main body due to the passing air that passes through the evaporator, so it is waterproof to mechanical parts and electrical parts inside the main body. There is a problem that it is necessary to take countermeasures or to take measures to prevent scattering outside the main body, and it is required to prevent the drain water from scattering without increasing the depth of the water tray.

  In addition, it is necessary to connect the condenser and the evaporator with a capillary tube as an expansion functional part and connect the pipe, but since the condenser and the evaporator are arranged separately, the piping path becomes long. Insufficient fixing in the middle of the piping may cause gas leakage due to the capillary tube diameter being thin, and measures against leakage of drain water generated on the surface of the capillary tube. Therefore, it is required to hold the capillary tube so as not to be cracked and to appropriately treat drain water leaking from the capillary tube.
