REFRIGERATION

Small amounts of liquid returning to the compressor is called ___________?

• Flood back

• Flooded start

• Slugging

• Flooding compressor

Refrigerant changes from vapor to a liquid in which component?

• Liquid line

• Evaporator

• Suction line

• Condenser

Which of the following will cause the compressor work harder?

• High suction pressure

• Low suction pressure

• Low charge

• Low load

It condenses the refrigerant vapor to liquid

• Condensor
• Compressor
• Evaporator
• Expansion Valve

reduces the pressure of the refrigerant liquid and thus cools the liquid

• Expansion Valve
• Evaporator
• Compressor
• Condensor

What is the compressor known as?

• The heart of the system.

• The leg of the system.

• The control system.

• The air system.

What is the temperature of the discharge line if you touch it.

• Warm

• Cool

• Cold

• Very Warm/Hot

What happens in the first 1/3 of the condenser?

• Refrigerant subcools

• Refrigerant superheats

• Refrigerant changes to 25 percent vapor and 75 percent liquid

• Refrigerant desuperheats

What is the job of the condenser?

• Create flash gas, superheat, cool refrigerant

• subcool, superheat, condense refrigerant

• meter refrigerant, create flash gas, condense

• desuperheat, condense, subcool refrigerant

What is the job of the expansion device?

• begin changing liquid into vapor by creating a pressure drop

• begin subcooling liquid by warming the vapor

• begin superheating vapor by cooling the liquid

• maintaining a constant pressure from the high side to the low side
