  "textContent": "A controller controls a displacement of a compressor which is installed in a refrigerant circuit of an air-conditioning system. The controller has a pressure difference detector (40, 54). An air conditioning switch (81) turns the air conditioning system on. A temperature detector (85) detects the temperature in a compartment. A control valve (CV) controls the displacement of the compressor such that the pressure difference detected by the pressure difference detector (40, 54) approaches a target value. A computer (70) determines the target value. The computer (70) changes the target value, depending on the detected temperature. The computer (70) limits the target value to a target value limit. After a predetermined time expires from when the air conditioning switch (81) is turned on, the computer (70) changes the limit. This permits the displacement of the compressor to be promptly and reliably changed.",
