Type I — Small AppliancesCâu 100 / 240
A technician connects recovery equipment to both the high and low sides of a small appliance during recovery. What is the main advantage of accessing both sides?
a.It eliminates the need for any recovery cylinder
b.It allows venting of noncondensables to the room
c.It converts passive equipment into active equipment
d.It speeds up recovery and helps remove more refrigerant from the system
Giải thích
Connecting to both the high and low sides opens more paths for refrigerant to flow out, which speeds recovery and helps reach the required recovery level. On a small sealed system this can shorten the job and improve completeness. It does not remove the need for a recovery cylinder, allow venting, or change the equipment type.
