Refrigeration Cycle 2

What is the compressor known as?

• The heart of the system.

• The leg of the system.

• The control system.

• The air system.

What state is the refrigerant in when leaving the compressor?

• 100 percent Low Pressure, low temperature, superheated vapor

• 100 percent High Pressure, high temperature, superheated vapor

• 100 percent Low Pressure, low temperature subcooled Liquid

• 100 percent High Pressure, high temperature subcooled Liquid

What is the state of the refrigerant entering the compressor?

• High pressure, high temperature, 100 percent superheated vapor

• High pressure, high temperature, 100 percent subcooled liquid

• Low pressure, low temperature, 100 percent superheated vapor

• Low pressure, low temperature, 100 percent subcooled liquid

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

• Warm

• Cool

• Cold

• Very Warm/Hot

What is the temperature of the suction line if you touch it?

• Warm

• Cold

• Cool

• Very Warm/Hot

What is the temperature of the liquid line if you touch it?

• Warm

• Cold

• Cool

• Very Warm/Hot

What is the temperature of the line at the outlet of the expansion device if you touch it?

• Warm

• Cold

• Cool

• 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
