Answer:
In-car temperature is controlled in a variable displacement compressor system by varying the capacity of the refrigeration not by cycling the compressor on and off.
Step-by-step explanation:
A Variable Displacement Compressor (VDC) works in a separate and rather more efficient manner than the fixed displacement compressor (FDC). The VDC automatically regulates the cooling effect of the refrigerator by changing its pumping capacity by means of a "wobbling piston" system.
During times of peak load, the refrigeration pumping capacity is increased, delivering a large flow rate of refrigerant, thus giving a high refrigerating effect. The reverse happens during times of load refrigeration load.
The fixed compressor tries to vary the temperature of the car by simply switching off the compressor, and turning it on during times of low and peak loads.
