Abstract: A power saving operational control method of an air conditioner adapted to maintain a room space at a pleasant state regardless of a distance from an indoor unit and size of the room space, thereby increasing a power saving effect, the method comprising the steps of: turning on or turning off a compressor according to a comparative result between a set-up temperature input by a user and room temperature to maintain the room temperature at the set-up temperature; discriminating whether a power saving operation signal is input; swinging the vertical/horizontal vanes vertically and horizontally to adjust directions of discharged air to the entire area of the room when it is discriminated at the signal input discriminate step that the power saving operation signal is input; discriminating whether the compressor is rendered active when it is discriminated at the signal input discrimination step that the power saving operation signal is input; calculating a power saving set-up temperature according to the room temp

Abstract: A wall type microwave oven having a hood device and an output control method thereof are disclosed. The microwave oven includes a first switch section for switching a power supply to a hood motor of the hood device, and a second switch section for switching power supply to a hood lamp of the hood device. A third switch section controls the output of the microwave oven by several stages. A control section switches/controls the third switch section, responsive to a control of the first or second switch section, such that when the microwave oven is operated with the hood motor or said hood lamp, output of the microwave oven is to be a low level.

Abstract: A multi-inverter air conditioner includes an outdoor heat exchanger having a refrigeration cycle, and a plurality of indoor heat exchangers connected to the outdoor heat exchanger by pipes and wire arrangements. Each indoor heat exchanger includes a control part for detecting a temperature of the respective pipe arrangement. Each pipe arrangement includes a pipe controller for opening the pipe. The outdoor heat exchanger comprises a control section for actuating the various pipe controllers and control parts for performing a test of the system. The outdoor heat exchanger further includes an input section for enabling a user to input a command signal to initiate the testing procedure, and a display section for displaying results of the test. During a test procedure, the temperatures of all pipe arrangements are detected before and after the refrigeration cycle has been actuated.

Abstract: An air conditioner includes a control device and a control method for transmitting and receiving wireless signals between a main control unit and a control selector of the air conditioner. A display unit displays room temperature, room humidity and air flow speed sensed by sensing devices.
