An electric compressor that uses the generator as a power source, a motor control means that controls the amount of electricity supplied to the compressor from the generator and changes the rotation speed of the compressor, and a refrigerator that detects the air temperature in the freezer. The rotation speed of the compressor is changed based on the internal temperature detection means and the detected temperature inside the freezer,
A vehicular refrigeration system comprising an internal temperature control means for performing feedback control so that the detected temperature approaches a target value, comprising: a rotation speed detection means for detecting the rotation speed of a compressor; and a lower limit value of the rotation speed of the compressor. is set, and when the rotation speed of the compressor reaches the lower limit value, a rotation speed control means that continues the operation of the compressor so that the rotation speed does not fall below the lower limit value, and a rotation speed control means that heats the air in the freezer. When operating the heater and compressor at the lower limit of rotation speed,
1. A refrigeration system for a vehicle, comprising: heater control means for controlling a heater with a calorific value corresponding to a supercooling load so as to bring the detected temperature inside the refrigerator closer to a target value.
