Question

Many refrigeration units use an open compressor. Which part of the compressor is most likely to weaken if the unit is not used for several months?

1) Piston
2) Crankshaft
3) Valve
4) Motor

Answer 1

The valve in an open compressor is likely to weaken if not used for several months due to the possibility of the seals drying out, causing cracks or loss of elasticity.

Step-by-step explanation:

The part of an open compressor that is most likely to weaken if the unit is not used for several months is the valve. Compressor valves are critical components that ensure proper compression cycle by controlling the flow of refrigerant within the system. If the unit is idle for an extended period, the valve seals may dry out, causing them to crack or lose elasticity. This can result in refrigerant leakage or inefficiency when the unit is restarted. Whereas the piston and crankshaft are more robust and less likely to be affected by inactivity, and the motor's primary risks involve electrical issues rather than inactivity alone.
