Abstract: Disclosed is an air conditioner that can operate in a general cooling mode in which indoor air is cooled by heat exchange with a first refrigerant in a main evaporator, or alternatively in a fast cooling mode in which the indoor air is primarily cooled by heat exchange in a midway heat exchanger which includes the main evaporator for the first refrigerant and a fast cooling condenser for a second refrigerant, and then re-cooled in a fast cooling evaporator for the second refrigerant. Accordingly, fast and agreeable air cooling can be achieved.

Abstract: A power-down control circuit utilizes the control signals employed in an active mode operation to operate when a power-down mode entry command is received during an active mode operation. The circuit is simplified requiring less area for devising the control circuit while lowering power consumption. The power-down control circuit in a semiconductor memory device includes at least a clock enable buffer unit, an external clock buffer unit, a latch unit, a control circuit for controlling internally operating clocks employed in active mode operation by using a control signal used in the active mode operation when a power-down mode entry command is received during the active mode operation, and a clock enable generation circuit for outputting clock enable signals for enabling entry to the power-down mode by using the clock control signals, when the external clock pulse signal is low level.

Abstract: Disclosed are a method for removing noise in an image, including the steps of: dividing image data contained in the image into predetermined unit areas; calculating each threshold corresponding to the unit area by using values of pixels contained in the unit area; detecting whether a first pixel containing impulsive noise exists in the unit area by using the calculated threshold; applying a median filter to the first pixel in the case the first pixel is detected; identifying a second pixel adjacent to the first pixel in the case the median filter is applied to the first pixel; and applying a mean-variance filter to the second pixel, and a system thereof.

Abstract: In an air conditioner, in a general cooling mode, an indoor air is cooled by heat exchange with a main evaporator of a first refrigerant, while in a rapid cooling mode, an indoor air is cooled by heat exchange with an intermediate heat exchanger consisting of a main evaporator of the first refrigerant and a rapid cooling condenser of a second refrigerant and then re-cooled in a rapid cooling evaporator of the second refrigerant, thereby performing a cool and pleasant cooling operation immediately whenever necessary.

Abstract: An air conditioner, in which a controller is installed separately from a plurality of indoor units and a plurality of outdoor units so that only the controller is added and conventional outdoor units are used when plural indoor units are required, thereby reducing costs due to the omission of other outdoor units. The controller determines whether or not the outdoor units are respectively operated according to a signal of a temperature sensing unit, and selectively operates the outdoor units according to a required capacity, thereby increasing the operating efficiency of the air conditioner.

Abstract: An air conditioner incorporates valve devices mounted in a plurality of indoor units, respectively, for allowing refrigerant discharged from an outdoor heat exchanger to be introduced into one or more indoor units that are in operation. The refrigerant is prevented from being introduced into the other indoor units that are not in use, and therefore, oil is prevented from being accumulated in the other indoor units that are not in use. Also, an appropriate amount of refrigerant is supplied to the indoor units that are in operation, and therefore, reliability and efficiency of the air conditioner are improved.

Abstract: An air conditioner and a method for controlling the same are disclosed herein. The air conditioner has a capillary tube equipped to a connecting tube which connects a suction pipe and a discharge pipe of a compressor and has an opening/closing valve equipped therein, thereby allowing pressure equilibrium between the suction pipe and the discharge pipe of a compressor to be maintained when the compressor stops operating, and allowing a discharge flux of the compressor to be appropriately controlled when a load is lower than a capacity of the controller under operation. As a result, the air conditioner does not require a separate bypass unit, thereby simplifying the construction of the air conditioner while minimizing the installation space thereof through omission of a separate bypass unit, leading to reduction in costs.

Abstract: Disclosed herein is an air conditioner having a single oil separator mounted on a confluent discharging channel, to which are connected discharging channels provided at a plurality of compressors, and an electronic expansion valve, of which the opening level is controllable, mounted on an oil collection pipe connected to the oil separator. As a result, the number of the oil separators is decreased. Consequently, the present invention has the effect of simplifying the structure of the air conditioner and reducing the manufacturing costs of the air conditioner. Furthermore, refrigerant is bypassed by controlling the opening level of the electronic expansion valve to control the flow rate of the refrigerant. Consequently, the present invention has the effect of eliminating an additional bypassing device, and therefore, simplifying the structure of the air conditioner and the controlling method of the air conditioner.

Abstract: An air-conditioner having multiple compressors includes: an indoor heat-exchanger disposed indoors and heat-exchanging indoor air; an outdoor heat-exchanger disposed outdoors and heat-exchanging a refrigerant with external air; four compressors for compressing the refrigerant to change the refrigerant to have a high temperature and high pressure; and three accumulators disposed at a suction side of the four compressors and separating the refrigerant into a gas and a liquid to supply a gaseous refrigerant to the compressors. Oil can be uniformly supplied to each compressor, thereby enhancing reliability of compressors, and since the three accumulators are small with low capacities, their installation space can be easily secured.
