Claim:
1. A container refrigeration system, comprising: a refrigerant circuit configured to perform a refrigeration cycle and including a compressor control section configured to, in a defrosting operation in which the compressed refrigerant of the compressor returns to the compressor through the hot gas bypass circuit and the evaporator and the evaporator is defrosted, control an operating speed of the compressor such that a pressure of the compressed refrigerant of the compressor reaches a target value; and a refrigerant amount control section configured to, depending on a superheating degree SH of the compressed refrigerant of the compressor in the defrosting operation, perform wherein in a cooling mode in which refrigerant circulates through the main circuit to perform the refrigeration cycle and an inside of a container is cooled,
