Type I — Small Appliances第 83 / 240 题
A window air conditioner has a burned-out, non-operating compressor. Using self-contained recovery equipment, what recovery level must the technician achieve?
a.90% of the refrigerant
b.80% of the refrigerant
c.4 inches of mercury (Hg) above atmospheric pressure
d.25 mm Hg absolute
解析
For a small appliance whose compressor is NOT operating, self-contained recovery equipment must remove at least 80% of the refrigerant. The 90% level applies only when the compressor still runs. A non-working compressor cannot help move refrigerant, so the lower percentage is allowed.
