Abstract: A movable multi-functional air-conditioner equipped with wheels for high mobility is disclosed having a front chamber with an air inlet and an air outlet, an evaporator and a fan mounted in the front chamber, a rear chamber with an air inlet and an air outlet, a heater and a condenser mounted in the rear chamber, a front valve mounted in the air inlet of the front chamber, a rear valve mounted in the air inlet of the rear chamber, and an intermediate valve for controlling the air passage between the front chamber and the rear chamber so that the user to select hot mode, cold mode, dehumidifying mode, or simultaneous dehumidifying and drying mode by opening/closing the front valve, the rear valve, and the intermediate valve.

Abstract: A power-saving drying machine control method used in a drying machine is disclosed to include the steps of (a) enabling the temperature (or relative humidity) control unit of a central control unit to start working and to detect the temperature (or relative humidity) at the exhaust port of the drying machine through a temperature (or relative humidity) sensor once per a predetermined time unit when the temperature (or relative humidity) sensor detected a predetermined temperature (or relative humidity) value, and (b) driving the central control unit to shut off the drying machine when at least two temperature (or relative humidity) differences of at least three proceeding temperature (or relative humidity) values obtained from the exhaust port of the drying machine through the temperature (or relative humidity) sensor are within the precision of the temperature (or relative humidity) sensor.
