All refrigeration systems containing more than 50 lbs of refrigerant must be repaired when the annual leak rate exceeds what percentage?

All refrigeration systems containing more than 50 lbs of refrigerant must be repaired when the annual leak rate exceeds what percentage?

• A. 20%
• B. 30%
• C. 35%
• D. 40%

Answer: (C)

The correct answer pertains to regulatory guidelines established by the Environmental Protection Agency (EPA) regarding the maintenance of refrigeration systems that contain significant quantities of refrigerant. According to the EPA’s regulations, any refrigeration system holding more than 50 pounds of refrigerant is required to be repaired when its annual leak rate exceeds 35%. This threshold is significant as it emphasizes the importance of maintaining proper refrigerant levels to minimize environmental impact, including the reduction of harmful greenhouse gases released into the atmosphere. In practice, a leak rate exceeding this percentage indicates a concerning level of refrigerant loss, necessitating prompt repairs to ensure system efficiency and compliance with environmental regulations. Maintaining such standards helps to foster more sustainable practices within the refrigeration industry. The percentage specified aligns with the EPA's commitment to reducing ozone-depleting substances and protecting the environment.
