Abstract

See full text

An air conditioning apparatus 1 includes first start control and second start control as its start control. In the first start control, first outdoor heat exchangers 24a, 24b are controlled to function as evaporators and second outdoor heat exchangers 25a, 25b are controlled to function as condensers. Thus, even when the compressors 21a, 21b are 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 compressors 21a, 21b from increasing. Also, after end of the first start control, the first outdoor heat exchangers 24a, 24b and second outdoor heat exchangers 25a, 25b are all controlled to function as evaporators, and the compressors 21a, 21b are 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.
