Abstract: An outdoor unit for an air conditioner may include a case, a controller disposed in the case, a coupling member configured to connect the case to the controller, and a cooling pipe coupled to one side of the controller so as to perform heat-exchange with the controller. The controller may include a first controller connected to the coupling member so as to be rotatably coupled to the case, and a second controller coupled to the cooling pipe so as to be fixedly installed inside of the case.

Abstract: An air conditioning apparatus may include an outdoor unit through which a first fluid, such as refrigerant circulates, an indoor unit through which a second fluid, such as water circulates, a heat exchange device which is configured to connect the outdoor unit to the indoor unit and in which the first fluid and the second fluid are heat-exchanged with each other, a first inner tube which is configured to connect the outdoor unit to the heat exchange device and through which the first fluid at high-pressure flows, a second inner tube which is configured to connect the outdoor unit to the heat exchange device and through which the first fluid at low-pressure flows, and a third inner tube which is configured to connect the outdoor unit to the heat exchange device and through which the first fluid in liquid form flows. The heat exchange device may include a bypass tube configured to bypass the second inner tube and a flow control valve provided in the bypass tube.
