CONTROLLING METHOD OF LAUNDRY TREATMENT APPARUTUS

摘要

PURPOSE: A controlling method of a laundry handling device is provided to reduce noise from a laundry handling device by controlling the rpm of a fan and the opening degree of an expansion valve. CONSTITUTION: A controlling method of a laundry handling device(100) is as follows. A fan(32) is rotated at a first RPM and the air is supplied by an air supply unit(22). The operating pressure of a compressor(26) is compared with a given reference. If the sensed operating pressure of the compressor is over the given reference, the RPM of the fan is controlled and the sensed operating pressure is controlled to belong to a confidence interval.
