Technician A says that a refrigerant identifier should be installed on the low-side, Technician B says that a refrigerant identifier should always be installed on the high-side. Who is correa? a. Technician A b. Technician B 6. Both Technician A and Technician B d. Neither technician A nor Technician B

The correct answer is b. Technician B.<br /><br />A refrigerant identifier should always be installed on the high-side of the refrigeration system. The high-side is the part of the system where the refrigerant is under high pressure, and it is the most accurate location to measure the refrigerant type. Installing the refrigerant identifier on the low-side would not provide accurate results, as the refrigerant would be under low pressure at that point. Therefore, Technician B is correct in stating that the refrigerant identifier should always be installed on the high-side.
