A device used to hold open the refrigeration compressor suction valve during starting to reduce the compression load is called what?
AI Explanation
The correct answer is A) cylinder unloader.
A cylinder unloader is a device used to hold open the refrigeration compressor suction valve during starting to reduce the compression load. This allows the compressor to start more easily by reducing the initial load on the system. The other options are incorrect because:
B) A relief valve is used to relieve excessive pressure in the system, not to assist with compressor starting.
C) A suction line bypass would bypass the compressor entirely, not just hold open the suction valve.
D) A discharge line bypass would not affect the suction side of the compressor.
