Abstract: An air conditioner and a method for detecting an incorrectly connected pipe in an air conditioner are provided. The air conditioner may detect an incorrectly connected pipe by performing a serial pipe inspection when three or less indoor units are connected to an outdoor unit through pipes and performing a group pipe inspection when four or more indoor units are connected to the outdoor unit through the pipes. The structure may enable detecting the incorrectly connected pipe among pipes connecting the outdoor unit to the indoor units within a shorter time.

Abstract: A method of controlling an air conditioner including activating a refrigeration cycle by driving an compressor; detecting a high pressure and a low pressure when the refrigeration cycle is activated; adjusting an operating frequency of the compressor based on the detected high pressure or low pressure of the refrigeration cycle; determining a current load of an inside space through a load detecting unit; determining a load level of the inside space by comparing the current load with a reference load; and determining the operating frequency of the compressor based on the determined load level.
