Concerning the piping schematic of the multi-temperature and multi-evaporator system as shown in figure "B" of the illustration, what statement is true? See illustration RA-0038.

Question

Accepted Answer

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.

Answer

The uppermost evaporator coil is a frosting evaporator and the lowermost evaporator coil is a non-frosting evaporator.

Answer

The hot gas solenoid valve opens under low load conditions to prevent frost build-up on the non-frosting evaporator coil.

Answer

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.
