CONTROL METHOD FOR A HYBRID REFRIGERATION SYSTEM

A method for controlling a transport refrigeration system (TRS) for refrigeration of a transport unit is disclosed. The TRS includes a TRS controller connected to the TRS for operating the TRS. The TRS includes an eutectic device including an eutectic medium, a transport refrigeration unit (TRU) having a refrigerant circuit for directing a refrigerant through the TRU and capable of directing the refrigerant to the eutectic device for cooling the eutectic medium. The TRS includes a cooling fluid circuit in thermal contact with the eutectic medium, wherein the cooling fluid circuit directs a cooling fluid to be in thermal contact with the eutectic medium.
