Abstract
The present invention has an object to provide a refrigeration cycle apparatus. A refrigeration cycle apparatus according to the present invention includes: a compressor; and a control apparatus configured to calculate a rotation number command of the compressor. The control apparatus includes a capacity controller configured to calculate the rotation number of the compressor as a capacity rotation number, a protection controller configured to calculate the rotation number of the compressor as a protection rotation number and a rotation number selection unit configured to select any one of the capacity rotation number and the protection rotation number as the rotation number command of the compressor. The rotation number command of the compressor is calculated so that at least any one of causing the current capacity value to approach the capacity target value and causing the protection variable to approach the protection target value is satisfied.
