Abstract
An outdoor air conditioner unit is connected to indoor units by a gaseous refrigerant communication pipe and a liquid refrigerant communication pipe. The outdoor air conditioner unit is provided with a gas-side shut-off valve and a liquid-side shut-off valve. The gas-side shut-off valve has a pipe connecting port to which the gaseous refrigerant communication pipe is connected. The liquid-side shut-off valve has a pipe connecting port to which the liquid refrigerant communication pipe is connected. In a plan view, the pipe connecting ports are offset from each other in both the depthwise direction and the widthwise direction. Thus, the outdoor air conditioner unit is configured to reduce interference between the refrigerant pipes connected to the gas-side and liquid-side shut-off valves of the outdoor unit.
