Abstract

PURPOSE: To improve dehumidification effects on bodily sensation, by operating an air conditioner in a dehumidification condition while suitably changing over the capacity of a compressor in response to dehumidification loads, to prevent the damages of the compressor due to the abnormal rise, etc. of high pressure when dehumidification operation by the high capacity operation of the compressor while ensuring the dehumidification operation that slightly belongs to cooling.
CONSTITUTION: When dehumidification operation, a cooling dehumidification change-over switch 13 is changed over to the dehumidification side. A pole number change-over switch 21 is changed over to the two pole side or the four pole side in response to dehumidification loads. IF changing over to the two pole side because dehumidification loads are large, an indoor fan motor 26 is conducted while high pressure refrigerant gas discharged from a pole change compressor 1, which is two pole operated, is radiation condensed at a heat exchanger 3 at the outdoor side, is changed into a high pressure refrigerant liquid, enters a 1st heat exchanger 5 at the indoor side through a magnet valve 9, radiates heat, works as a reheater, is pressure reduced at a pressure reducing mechanism 10 for dehumidification, and evaporates at a 2nd heat exchanger 7 at the indoor side, thus ensuring dehumidification action
