Question

When removing a diesel engine from a truck, Technician A says it is OK to disconnect an air con­ditioning hose, but the refrigerant should be vented to the outside of the shop. Technician B says do not loosen any air conditioning hoses until the refrigerant can be recovered. Who is right? *

Answer 1

Answer:

Technician B is right.

Explanation:

Air conditioning refrigerant contains Freon R22 and R410a, which have been linked to environmental damages, including ozone depletion, global warming, and energy-inefficiency.  For environmentally-savvy entities and individuals, there is the modern move to a more environment-friendly refrigerant, known as R-32.   Technician A's advice to vent the refrigerant outside the shop is in bad taste.  He does not seem to be aware of the environmental footprint of such an action.  Venting gas outside, in addition to the environmental damages, is also a waste of resources, and therefore, costly.  This is why Technician B's advice should be preferred.
