PROBLEM TO BE SOLVED: To continue air conditioning without causing an overload protector to operate even in a low voltage environment. SOLUTION: A variable capacity air conditioner variable in capacity in two stages by the switching of the displacement of a compressor 2 between FULL where all the cylinders are operated for a full capacity operation and SAVE where part of the cylinders are stopped for a controlled capacity operation has a voltage detector 3 or current detector 4 for selecting the FULL operation in a normal load state and switching to the SAVE operation in an overload state including a supply voltage reduction or overcurrent.
