Glossary
face-split
A type of finned-tube evaporator arrangement that splits the coil 
into parallel air paths.
fill
The heat transfer surface inside a cooling tower.
finned-tube evaporator
A type of evaporator where refrigerant flows through 
the tubes and air blows across the tubes and fins.
flash
The process of liquid refrigerant being vaporized by a sudden reduction 
of pressure.
hot gas muffler
A device installed at the discharge of the compressor to 
reduce noise and vibration associated with reciprocating compressors.
intertwined
A type of finned-tube evaporator arrangement that splits the coil 
by alternating the tubes fed in each row between two distributors.
liquid-line filter drier
A device installed in the liquid line to
 
remove moisture 
(water) and foreign matter, introduced during the installation process, from the 
refrigeration system.
moisture-indicating sight glass
See sight glass, moisture indicating.
orifice plate
A type of expansion device that uses a fixed plate with holes 
drilled in it to reduce the pressure and temperature of the refrigerant.
pressure–enthalpy chart
A graphical representation of the saturated 
properties of a refrigerant, plotting refrigerant pressure versus enthalpy.
pump-down cycle
A control sequence used in a refrigeration system to pump 
the refrigerant from the low-pressure side of the system to the high-pressure 
side of the system.
refrigeration effect
The amount of heat that each pound [kg] of liquid 
refrigerant will absorb when it evaporates.
row-split
A type of finned-tube evaporator arrangement that splits the coil by 
placing the independently-controlled coil sections in series in the airstream.
shell-and-tube evaporator
A type of evaporator where refrigerant flows 
through the tubes and water fills the surrounding shell.
shutoff valve
Devices used to isolate one part of the refrigeration system from 
the rest.
sight glass, moisture-indicating
A device installed in the liquid line, upstream 
of the expansion valve, used to detect moisture in the system and determine if 
the liquid refrigerant has flashed into vapor before entering the expansion 
valve.
solenoid valve
A device used to stop the flow of refrigerant within the 
refrigeration system.
