1. A The uppermost evaporator coil is a frosting evaporator and the lowermost evaporator coil is a non- frosting evaporator.
2. B The hot gas solenoid valve opens under low load conditions to prevent frost build-up on the non-frosting evaporator coil.
3. C The hot gas solenoid valve opens when the frosting evaporator requires defrosting and the bypass regulator injects enough liquid into the compressor suction line to prevent hermetic motor overheating.
4. D The hot gas solenoid valve opens when the frosting evaporator requires defrosting and the bypass regulator bypasses enough gas around the evaporator during defrosting to prevent liquid flood back to the compressor.
