(inverter-equipped) < Reheating only type > REDUCED ENERGY CONSUMPTION HITACHI Inverter control allows the unit to be used under a wide range of dehumidification load conditions as well as reducing energy consumption. It also makes it possible to reach the set humidity level within a shorter time and to respond to a greater fluctuation of dehumidification load. Depending on the fluctuation of the dehumidification load, the compressor speed is controlled by the inverter to adjust the dehumidification capacity. Compared to the constant speed type, power consumption is reduced as the unit runs more...
