Abstract: An air washer adsorbs outside contaminated air to disks, which have water films formed thereon, and settles contaminants in water in a water reservoir, thus purifying and humidifying air.

Abstract: A food refrigerator including a refrigerator compartment for storing therein kimchi, fruit, vegetables, greens, drinking water, wine, beer, etc., and an accessory storage compartment for storing therein a variety of accessories related to the use of the food stored in the refrigerator unit.

Abstract: Disclosed herein is an apparatus for controlling the capacity of an air conditioner and a control method using the same. The capacity control apparatus is configured in such a fashion that a 3-way or 4-way direction-switching member and a low-pressure equalizing solenoid valve are provided at a refrigerant path of the air conditioner having a pair of first and second compressors, so that the compression capacity of the air conditioner is adjusted into three stages of 100%, 60%, and 40% using the first and second compressors, enabling easy variable-capacity operation. This has the effect of considerably reducing energy consumption and of preventing wear of the first and second compressors via a rapid compensation of a pressure unbalance between both the compressors.

Abstract: Disclosed herein is an air conditioner having independent cooling and purifying paths. The air conditioner comprises a body casing formed by assembling a front panel with a rear panel, the front panel having a cooled air discharge opening and one or more suction openings to introduce indoor air into the body casing, a first fan arranged in the body casing to suction air via the suction openings, and a heat exchanger located above the first fan to perform heat exchange of the suctioned air. A cooler housing is arranged in the body casing to receive the first fan therein. Also, an air purifier is mounted in the body casing.

Abstract: A heat pump type air conditioner having an improved defrosting structure and a defrosting method for the same. When frost is not excessively accumulated on piping of an outdoor heat exchanger, a solenoid valve is controlled such that warm refrigerant from a compressor intermittently passes through a second pipe line, a heat discharging pipe line, and a third pipe line. When the air conditioner is operated in heating mode, the amount of frost accumulated on the outdoor heat exchanger is deduced from the temperature of the piping of the outdoor heat exchanger, and then a defrosting operation is performed based on the temperature of the piping of the outdoor heat exchanger. Consequently, the frost accumulated on the outdoor heat exchanger is quickly removed based on the amount of frost accumulated on the outdoor heat exchanger, and the period of time for which the air conditioner is not operated is reduced, whereby more comfortable and pleasant heating function is provided to a user.

Abstract: Disclosed is a spiral heat exchanging device having an improved cooling efficiency in which a plurality of spiral pipes connected to an inlet pipe for introducing a coolant are formed to be spirally wound with a gradually increased diameter toward a blast fan and the coolant is discharged through a discharge pipe so that the wind generated from the blast fan is spread evenly on the spiral pipes.
