Refrigerant Components and Cycle

The component responsible for absorbing heat and changing liquid refrigerant to a vapor.

• Evap.

• Cond.

• Comp.

• Metering Device.

State of the refrigerant leaving the cond. coil

• HPHT vapor

• LPLT vapor

• HPHT liquid

• LPLT liquid

Device that restricts the flow of refrigerant based on the temperature of the refrigerant leaving the evap coil.

• AXV

• TXV

• Capillary Tube

• Piston

A system that has an evaporator coil that is 70 degrees is working properly.

• True

• False

The refrigerant leaves the compressor as a _______________

What will happen to a system with a blocked return air filter?

• The evap. coil will freeze

• The refrigerant won't be cooled in the condenser coil.

• The metering device will become restricted

• Nothing, the system will work fine.

What will happen to a system with a bad cond. fan?

• The compressor will freeze

• The system will work properly just have to work harder.

• The refrigerant will not change state from a vapor to a liquid

• The refrigerant will not change from a liquid to a vapor.

The line between the condenser coil and metering device is known as:

• Suction Line

• Water Line

• Discharge Line

• Liquid Line

The state of the refrigerant in the suction line?

• LPLT Liquid

• LPLT Vapor

• HPHT Liquid

• HPHT vapor

The state of the refrigerant in the discharge line

• LPLT liquid

• LPLT Vapor

• HPHT Liquid

• HPHT Vapor
