Disclosed is a refrigerator including an ultrathin wall type insulating wall having a reduced thickness while maintaining insulating performance, so as to increase the capacity of a storage chamber. A vacuum insulating material is disposed inside the insulating wall so as to ensure the insulating performance of the insulating wall, and a foam material, in the portion in which the vacuum insulating material is not disposed, is disposed to be thicker than a foam material in the portion in which the vacuum insulating wall is disposed, such that the insulating wall, which maintains insulating performance while maintaining the insulating wall having an overall ultrathin shape, can be formed. Furthermore, auxiliary vacuum insulating materials are additionally disposed in the insulating wall corner regions in which the vacuum insulating material is not disposed, such that the ultrathin wall-type insulating wall is formed while maintaining the overall insulating performance of the refrigerator, thereby reducing the total thickness of the insulating wall so as to increase the capacity of the storage chamber, and enabling a slim design of the refrigerator such that the aesthetics of the refrigerator can be improved.

Refrigerator and manufacturing method therefor

Disclosed herein is a water softening apparatus including an electrosorption unit to adsorb foreign matter contained in water with electrical attraction, a preprocessing unit having a preprocessing chamber which is connected with an external water supply source and is provided with a filter to filter out foreign matter contained in water transferred from the external water supply source, and a cleaning solution supply unit having a cleaning solution storage chamber which stores a cleaning solution to be supplied to the electrosorption unit. Since any one of the water transferred from the preprocessing unit and the cleaning solution transferred from the cleaning solution supply unit is selectively transferred to the electrosorption unit by a valve, a pump to inject the cleaning solution and the like are unnecessary.

Water softening apparatus

A method to control the sleep operation of an air conditioner is provided. The method includes determining whether or not a sleep operation is activated and sequentially performing a plurality of sub-modes of the sleep operation when the sleep operation is activated.

Method to control sleep operation of air conditioner

A compressor controlling apparatus including a bypass unit connected between an outlet and an inlet of the compressor and a control unit. The control unit reduces pressure difference between the outlet and the inlet of the compressor by the bypass unit to start the compressor when the compressor is to be started. The compressor is started while pressure equilibrium is achieved by the bypass unit, thereby preventing poor start-up of the compressor caused due to excessive pressure difference, and thus improving reliability of the compressor.
