Regulations & Safety第 63 / 240 题
Why is it important to never mix different refrigerants in the same recovery cylinder?
a.There is no problem mixing refrigerants
b.Mixed refrigerants usually cannot be reclaimed and often must be destroyed at added cost
c.Mixed refrigerants weigh less and are easier to carry
d.Mixing improves the resale value
解析
Mixing different refrigerants in one cylinder generally makes the mixture impossible to reclaim to a purity standard, so it often must be destroyed, which is costly and wasteful. Mixing does not reduce weight, improve resale value, or come without consequences. Technicians should dedicate cylinders to a single refrigerant and label them clearly.
