A refrigerated warehouse uses a commercial refrigeration system with 300 pounds of refrigerant. What annual leak rate threshold applies to commercial refrigeration under the current rules?

a.10 percent
b.20 percent
c.30 percent
d.50 percent

Explanation

Commercial refrigeration appliances have a leak rate threshold of 20 percent per year, higher than the 10 percent for comfort cooling but lower than the 30 percent for industrial process refrigeration. A 50 percent threshold does not exist under the rule. Once the calculated annual leak rate exceeds 20 percent, repairs must generally be completed within 30 days.
