EPA 608 Type III · Leak Repair Requirements · Hard
A chiller with a 1,000-lb full charge needs 50 lbs added, 73 days after the last addition. What is its annualized leak rate?
Answer: D. 25%.
- A5%.
- B10%.
- C20%.
- D25%.✓ Correct
Why D is right
Annualizing method: (50 ÷ 1,000) × (365 ÷ 73) × 100 = 0.05 × 5 × 100 = 25% per year. That is well above the 10% threshold for comfort cooling.
