Question

All refrigeration systems containing more than 50 lbs. of refrigerant must be repaired when the annual leak rate exceeds___?

Answer 1

All refrigeration systems containing more than 50 lbs. of refrigerant must be repaired when the annual leak rate exceeds 20%.

Step-by-step explanation:

All refrigeration systems containing more than 50 lbs. of refrigerant must be repaired when the annual leak rate exceeds 20%.

To calculate the annual leak rate, you need to know the total amount of refrigerant in the system and the amount leaked over a specific period of time. Once you have these numbers, you can use the formula:

Annual leak rate = (Amount leaked / Total refrigerant) * 100%

For example, if a refrigeration system contains 100 lbs. of refrigerant and 5 lbs. of refrigerant is leaked over a year, the annual leak rate would be:

Annual leak rate = (5 lbs. / 100 lbs.) * 100% = 5%

Since the question states that the annual leak rate must exceed a certain value, the refrigeration system must be repaired when the annual leak rate exceeds 20%.
