Regulations & Safety第 45 / 240 题
An industrial process refrigeration system in a chemical plant contains 1,000 pounds of refrigerant. Which annual leak rate threshold applies?
a.10 percent
b.20 percent
c.30 percent
d.15 percent
解析
Industrial process refrigeration has the highest leak rate threshold at 30 percent per year, reflecting the large charges and specialized nature of these systems. Comfort cooling is 10 percent and commercial refrigeration is 20 percent, while 15 percent was part of the older pre-2019 framework. Exceeding 30 percent triggers the repair and, if needed, retrofit or retirement requirements.
