Technician A says that high pressure in recycled refrigerant is only caused by air contamination. Technician B says that recycled refrigerant should have the same purity standards as new refrigerant Who is correct? a. A onlyb. B onlyc. both A and Bd. neither A and B

a. A only

Explanation:

When air, is in excess of allowable amounts, it can cause the system to operate at pressures that are higher than normal. This means that the recycled refrigerant is operating at high pressure. Thus Technician A is correct.

However, Technician B is incorrect because unlike reclaimed refrigerants where the process strip the refrigerant of impurities making it to meet the standards of a new refrigerant, the recycled refrigerant is not as pure as it's contaminants are only reduced.

Therefore, only technician A is correct.
