Question: Why is it critical to recover refrigerant rather than simply venting it into the atmosphere?
Answer options:
- To prevent over-pressurization of the system ✅ To comply with environmental regulations and prevent ozone depletion/global warming
- To reuse the refrigerant without any processing
- To ensure the system components remain dry
Correct answer: To comply with environmental regulations and prevent ozone depletion/global warming
Explanation: Releasing refrigerants into the atmosphere is illegal in Canada due to their environmental impact (ozone depletion by ODS like HCFCs and global warming potential by HFCs). Recovery allows for recycling or proper disposal.
