Access Valve
- Access port on the evaporator that allows service personnel to check system pressure.
Accumulator -
A device installed on the suction line that is used to boil off small amounts of liquid refrig-
erant so liquid does not reach the compressor.
Compressor -
An electrically driven piston pump that pumps vapor refrigerant from a low pressure level
to a higher pressure level.
Condenser -
The component in a refrigeration system that transfers the heat that was absorbed by the
refrigerant in the evaporator and the heat of compression from the system by condensing the refrigerant.
Condenser Fan -
Fan that forces air through the air cooled condenser to aid heat transfer.
Dual Pressure Control
- A device that protects the compressor from low charge and high pressure.
Evaporator -
The component of the refrigeration system that absorbs heat from the air by boiling liquid
refrigerant to vapor.
Evaporator Fans -
Fans that circulate air through the case and force air through the evaporator to aid heat
transfer.
Filter Drier -
A device installed on the liquid line of a refrigeration system that removes water and other
impurities from the refrigerant in the lines during initial start-up.
High Pressure Warning Light
- Indicator light that warns the operator that the system pressure is to high.
Receiver -
The component in a refrigeration system that stores liquid refrigerant that is not being used by
the system in low load conditions or when the system is shut down.
Service Valve -
A manually operated valve in the refrigeration system that is used for various service oper-
ations such as isolating the high or low sides of the system.
Suction Line Solenoid
- A device that prevents liquid from entering the compressor.
Thermostatic Expansion Valve (TXV) -
A valve that controls the flow of liquid refrigerant to the evapo-
rator coil and also separates the high pressure side of the system from low pressure side of the system.
Thermostatic Expansion Valve (TXV) Bulb -
A bulb that is attached to the suction line of the evapora-
tor that controls the TXV. Inside the bulb is a charge that reacts to temperature and regulates the flow of
refrigerant through the expansion valve.
