METHOD OF INSPECTING AIR CONDITIONER

摘要

A method for inspecting an air conditioner is provided to shorten the installation state inspecting time by inspecting mal-piping of indoor units with respect to all MCUs. An air conditioner includes a plurality of indoor units(140a~140d) and a plurality of mode converting units(160). The indoor unit includes a cooling valve and a heating valve. The mode converting units are connected to the indoor units through pipes. The mode converting unit controls the cooling operation mode and the heating operation mode of the indoor unit by regulating the flow of refrigerant to the indoor unit. All of the indoor units are operated for a predetermined period of time in one of the cooling operation mode and the heating operation mode. If the corresponding operation mode is normally performed in all of the indoor units, one of a cooling valve and a heating valve which corresponds to the corresponding operation is determined to be normally operated.
