Question 145Refrigeration & AC - Assistant Engineer

The correct answer is B) recovery of the refrigerant. Before a system can legally be opened up for repairs, the refrigerant must be recovered and not vented to the atmosphere. This is a requirement under the Clean Air Act and its regulations, which prohibit the venting of halogenated fluorocarbon refrigerants. Recovering the refrigerant ensures that it is properly contained and can be reused or reclaimed, rather than being released into the environment. The other options, such as destruction, reclamation, or recycling, may be necessary steps after the refrigerant has been recovered, but recovery is the minimum required action before the system can be opened for repairs.
