Both the evaporator and the condensing coil have high heat transfer efficiency to increase the cooling (heating) capacity of the unit and reduce the input power.\r\nThe capacity of the unit can be intelligently adjusted according to the load condition, so that the operating capacity matches the actual load, so as to improve the working efficiency of the compressor and reduce power consumption.\r\nUsing self-adjusting intelligent defrost mode, the defrost is accurate and effective to avoid heat loss.
