PROBLEM TO BE SOLVED: To suppress deterioration in air conditioning feeling, while suppressing an increase in power consumption of an air conditioner in a vehicle having PTO. SOLUTION: When discharge pressure Pd of a compressor 10 exceeds a prescribed value, discharge capacity of the compressor 10 is lowered, regardless of thermal load, and thereby rise speed of the discharge pressure Pd can be decreased. Since time required for raising the discharge pressure Pd up to pressure Pdmax in which the compressor 10, that is, a vapor compression type refrigerating machine has to be substantially stopped becomes long, a working ratio (working time) of the compressor 10 can be increased. As a result, frequent repeating of an action for cooling indoor air raised in temperature again while stopping the compressor 10 can be suppressed, and thereby an increase in power consumption in an air conditioner, that is, the vapor compression type refrigerating machine can be suppressed and deterioration in air conditioning feeling can be suppressed.
