What is the primary function of refrigerant recovery machines in HVAC systems?
✔✔ Refrigerant recovery machines are used to remove refrigerant from an HVAC system before
service, repair, or disposal, ensuring that refrigerants are captured and recycled or properly
disposed of to prevent environmental harm.
How does the use of certified recovery equipment contribute to environmental protection?
✔✔ Certified recovery equipment is designed to meet safety and efficiency standards, ensuring
that refrigerants are recovered effectively and that leaks or emissions are minimized, thus
protecting the environment.
What is the procedure for handling refrigerants that are no longer in use?
1
, ✔✔ Refrigerants that are no longer in use should be recovered using appropriate equipment,
stored in certified recovery cylinders, and either recycled or disposed of through authorized
facilities according to environmental regulations.
Why is it important for technicians to be aware of the ozone depletion potential (ODP) of
refrigerants?
✔✔ Awareness of ODP helps technicians choose and manage refrigerants in a way that
minimizes their impact on the ozone layer, aligning with regulatory standards aimed at reducing
ozone depletion.
What are the key differences between high-pressure and low-pressure refrigerants in terms of
system handling?
✔✔ High-pressure refrigerants require specific recovery and handling procedures due to their
operating pressures, whereas low-pressure refrigerants have different handling and recovery
requirements to ensure safe and effective management.
What should a technician do if they encounter a refrigerant leak during system maintenance?
