Question

Lorenzo Alberto · Accepted Answer

Final Answer : B, Explanation :  Technician B is correct because R-22, a refrigerant with ozone-depleting potential, was indeed used in refrigerated trailers until 2020. Technician A is incorrect as cryogenic reefers do not have a heavy carbon footprint or ODP rating since they use liquid nitrogen or carbon dioxide, which do not deplete the ozone layer.
