🔍 Key Concepts

• How refrigeration compressors are started under reduced load to prevent motor overload • The difference between a bypass line and a mechanism on the compressor itself • What happens when the suction valve is held open during the compression stroke

💭 Think About

• Which option describes something that actually holds a valve open on the cylinder rather than routing refrigerant around it? • If the suction valve is held open during the piston’s upstroke, what happens to the gas and the effective compression in that cylinder? • Among the choices, which term is commonly associated with capacity control or load reduction on a multi-cylinder compressor?

✅ Before You Answer

• Identify which choices are piping/valve arrangements in the lines versus a mechanical device on the compressor cylinder • Confirm which term is used in marine refrigeration texts for capacity control by disabling compression in one or more cylinders • Verify that the correct option directly involves the suction valve on the compressor cylinder and not just line pressure relief
