Abstract: An evaporative condenser having improved condensation efficiency is provided. The evaporative condenser includes a condensation module including a connecting tube, a water injection module spraying water passing through the condensation module, above the condensation module, and a blowing module disposed on one side of the condensation module and supplying air passing through the condensation module. In the condensation module, N header rows including a first header extending in a first direction and having a flow path therein, a second header extending in the first direction and having a flow path therein, and a plurality of connecting tubes extending in a second direction between the first header and the second header and connecting the flow paths of the first header and the second header are stacked in a third direction, where N is a natural number greater than or equal to 2.

Abstract: An air conditioner having a water nozzle cleaning system for cleaning a water nozzle spraying water to a heat exchanger, and a braking control method used therein are provided, the air conditioner including an evaporator, an expansion valve, a compressor and an evaporative condenser through which refrigerant circulates includes a water supply line including a first water line and a second water line branching from a water supply source and a third water line at which the first water line and the second water line are joined, and configured to supply water to the evaporative condenser; and a water control module including a control unit configured to control the water supply line.

Abstract: Accordingly, the present disclosure provides an air conditioner including an evaporator, an expansion valve, a compressor, and an evaporative condenser through which refrigerant circulates, comprising: an outdoor unit in which the evaporative condenser is disposed; an indoor unit in which the evaporator is disposed; and a control unit connected to the indoor unit and the outdoor unit; wherein the evaporative condenser includes a cooing flow path through which a refrigerant passe and a condenser injection water module providing water to the cooling flow path, the outdoor unit includes first control valve for controlling water supplied to the condenser injection water module, and the control unit is connected to the first control valve and the evaporative condenser, and changes the amount of water supplied through the first control valve according to operating conditions.

Abstract: A system for ventilation, dehumidification, and cooling according to an exemplary embodiment in the present disclosure may include an outdoor unit dehumidifying and cooling introduced outside air; and an indoor unit connected to the outdoor unit to perform ventilation, in which the outdoor unit includes a dehumidification rotor, an evaporative cooler, an evaporative condenser, a ventilation damper, a heating unit, and a control module operating and stopping at least one of the dehumidification rotor, the evaporative cooler, the evaporative condenser, the ventilation damper, or the heating unit.

Abstract: An indoor unit of an air conditioner with an electronic expansion valve. The indoor unit includes a main body, a heat exchanger disposed at the front portion of the inside of the main body, a control unit, in which electrical components are mounted, disposed at the outside in the lengthwise direction of the heat exchanger, a control case including a first side surface part disposed between the control unit and the heat exchanger and an extension part connected with the first side surface part and extended in the lengthwise direction of the heat exchanger, and an electronic expansion valve disposed in a space defined by two surfaces neighboring with each other by the extension part.
