The Refrigeration Cycle

Superheating will be found in which of the following locations?

• Discharge line

• Liquid line

• Suction line

• Expansion line

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

The area between the valve plate and the top of the piston at top dead center is _____?

• Discharge valve

• Suction valve

• Clearance volume

• Wrist pin

What is the function of Evaporator in an AC refrigeration cycle?

• Absorbs heat from the room

• Compresses gas

• Reduces temperature of refrigerant

• Reduces temperature of refrigerant

What is the function of Compressor in an AC refrigeration cycle?

• Absorbs heat from the room

• Compresses gas to ensure circulation

• Reduces temperature of refrigerant

• Converts gas into liquid

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 Function of Condenser in an AC Refrigeration Cycle ?

• Compresses the gas to ensure circulation

• Reduces the temperature of the refrigerant

• Converts gas into liquid

• Absorbs heat from the room
