EPA regulations require that leaking commercial and industrial process refrigeration be repaired when the leak rate exceeds ____________ percent of the charge each year.

EPA regulations require that leaking commercial and industrial process refrigeration be repaired when the leak rate exceeds ____________ percent of the charge each year.

• A. 0
• B. 15
• C. 25
• D. 35

Answer: (D)

The correct percentage is 15. Under EPA regulations, commercial and industrial process refrigeration systems must be repaired if the annual leak rate exceeds 15 percent of the total refrigerant charge. This regulation is in place to prevent excessive greenhouse gas emissions and to promote environmentally responsible practices in refrigeration. Repairing leaks helps ensure efficiency and compliance with environmental standards, thereby minimizing the impact on ozone depletion and climate change. This regulation is vital for maintaining both the performance of refrigeration systems and adherence to legal requirements.
