A device that allows a technician to gain access to the 

refrigeration system for charging or measurement.

A type of condenser where refrigerant flows through the 

tubes and rejects heat to air that is drawn across the tubes.

American Society of Heating, Refrigerating and Air-Conditioning 

Engineers

A type of expansion device that uses a long, narrow tube to 

reduce the pressure and temperature of the refrigerant.

A type of air-cooled condenser that uses 

a centrifugal fan instead of a propeller fan, allowing it to overcome the larger 
static pressures associated with ductwork.

The mechanical device in the refrigeration system used to 

increase the pressure and temperature of the refrigerant vapor.

The component of the refrigeration system where refrigerant 

vapor is converted to liquid as it rejects heat to water or air.

A device used to reject the heat from a water-cooled condenser 

by spraying the condensing water over the fill while drawing outdoor air 
upward through the fill.

A device used to ensure uniform refrigerant distribution through 

the multiple-coil circuits of a finned-tube evaporator.

A type of expansion device that uses an 

electronically-actuated valve to sense and control the flow rate of liquid 
refrigerant to the evaporator.

The property of a refrigerant indicating its heat content, both 

sensible and latent, per pound [kg] of refrigerant.

A type of condenser where refrigerant flows through 

the tubes and rejects heat to air. The air is drawn across the tubes, which are 
wetted on the outside by circulating water.

The component of the refrigeration system where cool liquid 

refrigerant absorbs heat from air, water, or some other fluid, causing the 
refrigerant to boil.

The component of the refrigeration system used to reduce 

the pressure and temperature of the refrigerant.

The type of expansion device that maintains the pressure 

difference between the high-pressure and low-pressure sides of the system. It 
also maintains the proper amount of superheat in the system by metering the 
quantity of liquid refrigerant entering the evaporator, ensuring that the 
refrigerant will be completely vaporized within the evaporator
