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.Convert the fridge to a Type II appliance
b.Locate and repair the leak when practical rather than repeatedly recharging a leaking sealed system
c.Add refrigerant repeatedly, since small appliances are exempt from leak repair
d.Vent the old charge and add a full new charge
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.
