A compression refrigeration system includes a switch to select between a plurality of operation modes of a metering device that controls a rate of flow of a refrigerant to an evaporator of the compression refrigeration system. Each operation mode is associated with a respective refrigerant. Further, the compression refrigeration system includes a reference database that comprises pressure-temperature data associated with a plurality of refrigerants. Furthermore, the compression refrigeration system includes a valve adjustment engine that is communicatively coupled to the switch and the reference database. The valve adjustment engine controls the metering device based on an operation mode of the metering device that is selected using the switch. The operation mode is selected based on a refrigerant with which the compression refrigeration system is currently charged.
