Abstract: Disclosed is an ice making device that is able to selectively make ices having different transparencies from each other. The ice making device includes: an ice making chamber including an ice making container to accommodate ice making water therein; a cooler configured to supply cool air to the ice making chamber to cool the ice making water; an ice making fan configured to circulate the supplied cool air; an ice making heater configured to supply heat to the ice making water when the ice making water is cooled; and a controller configured to control at least one of the cooling unit, the ice making fan and the ice making heater to adjust a rate of change of temperature of the ice making container to generate one of two types of ice having different transparency. The ice making device may adjust the rate of change of temperature of the ice making container to have the transparency desired by a user.

Abstract: An air conditioner includes a dust collection sheet including a first electrode and a second electrode separated from the first electrode and facing the first electrode, and to collect particles in air, a power supplier electrically connected to the first and second electrodes, and a controller configured to control the power supplier to apply a direct current (DC) voltage to the first electrode to perform a dust collecting operation, determine to perform at least one of a first sterilizing operation at a preset first temperature for a first period of time and a second sterilizing operation at a second temperature higher than the first temperature for a second period of time shorter than the first period of time, and control the power supplier to apply an alternate current (AC) voltage to the first electrode and the second electrode for the first sterilizing operation or the second sterilizing operation.
