Abstract: An outdoor unit includes a casing including an air passage, an outdoor fan disposed in the air passage, a compressor disposed in the casing, an outdoor heat exchanger disposed in the casing and including fins and a heat transfer tube connected to the fins, a control board disposed in the casing and including a control unit that controls the compressor, and a heat sink disposed in the air passage in the casing and being in contact with the control board. The heat transfer tube of the outdoor heat exchanger includes a first region in which gas refrigerant or two-phase gas-liquid refrigerant flows when the outdoor heat exchanger is used as a condenser and a second region that is located downstream of the first region in a refrigerant flow direction and in which single-phase liquid refrigerant flows.

Abstract: A monitoring and controlling apparatus includes a functional cabinet, functional units, and a control cabinet. The functional cabinet includes a plurality of frames and a door at an opening of at least a part of the frames, each frame having a predetermined accommodation size. Each functional unit is detachably accommodated in respective frame and including a circuit and a component for a function of the functional unit. The control cabinet is disposed next to the functional cabinet, and configured to monitor and control the functional units.
