Recovery & Recycling第 211 / 240 题
The main danger of overfilling a recovery cylinder beyond 80 percent is that:
a.The refrigerant will lose purity
b.The valve will freeze open
c.As temperature rises the liquid can expand and hydraulically rupture the cylinder
d.The cylinder color will fade
解析
An overfilled cylinder has no room for the liquid to expand, so a rise in temperature can make it hydraulically full and burst it, releasing refrigerant with great force. This is why the 80 percent limit and weighing are strict rules. Overfilling is one of the most serious cylinder hazards.
