Abstract
An air conditioning apparatusincludes first start control and second start control as its start control. In the first start control, first outdoor heat exchangersare controlled to function as evaporators and second outdoor heat exchangersare controlled to function as condensers. Thus, even when the compressorsare driven on at a given rotation number, the discharge pressures thereof can be prevented from increasing, thereby being able to prevent the internal pressures of the compressorsfrom increasing. Also, after end of the first start control, the first outdoor heat exchangers, 24and second outdoor heat exchangersare all controlled to function as evaporators, and the compressorsare driven on at a given rotation number. This can shorten the rising time of the heating capacity in the start of the normal heating operation.
