Type I — Small Appliances第 116 / 240 题
A homeowner offers to help a Type I technician 'top off' a leaking mini-fridge instead of finding the leak. What is the best professional practice?
a.Add refrigerant repeatedly, since small appliances are exempt from leak repair
b.Locate and repair the leak when practical rather than repeatedly recharging a leaking sealed system
c.Vent the old charge and add a full new charge
d.Convert the fridge to a Type II appliance
解析
Repeatedly recharging a leaking sealed system wastes refrigerant and allows continued release, so the proper practice is to find and repair the leak when practical. Good service reduces emissions and gives the customer a lasting fix. Venting the old charge would be illegal, and adding refrigerant without addressing the leak is poor practice.
