Abstract: An air conditioner is disclosed which includes a damper adapted to select a desired path of air humidified by a moisture release portion of a desiccant wheel in accordance with a humidification or dehumidification mode. In accordance with operation of the damper, humidified air is heat-exchanged in a heat exchanger in the dehumidification mode, so that the air is dehumidified. The dehumidified air is discharged into a room. In the humidification mode, the humidified air is directly discharged to the room. Thus, the air conditioner can be used as a humidifier or dehumidifier in accordance with a user selection.

Abstract: A humidifier is disclosed which includes a desiccant wheel, and a heat exchanger adapted to heat-exchange air dehumidified in an absorption chamber with air introduced into a regeneration chamber. The heat of the air dehumidified in the absorption chamber can be used to increase the temperature of ambient air introduced into the regeneration chamber, thereby reducing the load of a heater to heat the temperature of the ambient air introduced into the regeneration chamber, and thus, achieving a reduction in the power consumption of the heater.

Abstract: An air conditioner is disclosed which uses a single blowing fan having one inlet and a pair of outlets to suck air from a room or from the outdoors and to blow a fraction of the sucked air to a dehumidification flow path while blowing the remaining fraction of the sucked air to a regeneration flow path. Accordingly, it is possible to reduce the number of elements constituting the air conditioner, and thus, to reduce the installation costs. Also, it is possible to design a compact structure of the air conditioner.

Abstract: A heat exchanger of an air conditioner is disclosed whereby refrigerant is not biased to a particular heat exchange line but evenly flows in all heat exchange lines. The heat exchanger includes a housing having air inlets and an air outlet; and a plurality of heat exchange lines each formed inside the housing in a serpentine shape for refrigerant to flow and switch the flow direction. The plurality of heat exchange lines are arranged in such a manner that each line crosses each other before and after the infusion directions of air introduced via the air inlets. Each heat exchange line is substantially the same diameter and length. An air quantity initially contacting each heat exchange line is substantially the same, and a heat exchanged quantity of the refrigerant passing through each heat exchange line is substantially the same.

Abstract: A heat exchanger of an air conditioner comprising: at least one or more refrigerant inlets for connecting a compressor for compressing refrigerant to an expansion device for expanding condensed refrigerant via a piping and for receiving high temperature/pressure refrigerant coming from the compressor via a four-way valve; at least one or more refrigerant outlets for discharging the refrigerant to the expansion device, wherein the number of the refrigerant outlets is greater than that of the refrigerant inlets, such that same performances can be achieved for both the cooling and heating purposes albeit the heat exchanger being simplified in the structure thereof, and manufacturing cost can be reduced to thereby improve the productivity.

Abstract: A capacity-variable air conditioner is capable of controlling capacity and consumed electricity in response to operation mode. The refrigerant compression quantity of a compressor is variably adjusted by control of open/close operation modes via selective combination of open/close valves of bypass pipes and bypass valve of the compressor in response to the operation mode. The capacity-variable air conditioner discharges some of the refrigerant infused into the compressor while the bypass valve of the compressor is opened under energy saving operation mode, such that refrigerant circulation quantity can be adjustably reduced under the energy saving operation mode where load of the compressor is less than that of a normal operation mode, thereby enabling a reduction in the capacity and consumed electricity.

The present invention includes periodically detecting a zero crossing time point of an inputted voltage, turning on the power factor compensation switch if a turn-on time point of the power factor compensation switch set to a time point delayed by a prescribed time from the detected zero crossing time of the inputted voltage is reached, and turning off the power factor compensation switch if a prescribed time passes after turning on the power factor compensation switch.

Abstract: A slim-type air conditioner is provided. The slim-type air conditioner blows air by a plate reciprocating back and forth. Accordingly, the air can be discharged through a wide outlet hole, and the size and thickness of the air conditioner can be reduced. Therefore, the convenience of users and installers can be improved.
