Refrigeration Valve Design and Functions Quiz pt3

What is the function of the solenoid valve located between F-l and G-2 in a refrigeration system?

• Stops liquid refrigerant flow to the freezer evaporator during the defrost cycle and when the compressor cycles off

• Starts liquid refrigerant flow to the freezer evaporator

• Diverts refrigerant vapour directly to the condenser coil

• Regulates the pressure in the evaporator

What is the purpose of the check valve located between B-4 and C-5 in a refrigeration system?

• Prevents refrigerant from flowing into the heat reclaim coil

• Allows refrigerant to flow into the heat reclaim coil

• Diverts refrigerant vapour directly to the condenser coil

• Regulates the pressure in the evaporator

What does the three-way diverting valve at B-6 do in a refrigeration system?

• Stops liquid refrigerant flow to the freezer evaporator

• Prevents refrigerant from flowing into the heat reclaim coil

• Shifts the direction of flow from the condenser coil to the heat reclaim coil

• Diverts refrigerant vapour directly to the condenser coil

What is the function of the evaporator pressure-regulating (EPR) valve located between J-3 and K-4 in a refrigeration system?
