REFRIGERATION PIPING

Refrigeration components for OWZA cases are easily acces- sible in the tank and beneath the case.

The expansion valve and suction line 1/4” access valve are both located on the front-left side of the tank and are acces- sible without lifting the fan plenum. These components may be reached by lifting only the left-hand deck pan which mini- mizes the need to remove product.

The diagram on page 7 illustrates all of the refrigeration components in the case – the box-shaped dotted line indicates those components that are located within the case tank.

Basic definitions of these components are listed below.

*

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 refrigerant so liquid does not reach the compressor.

Compressor

An electrically driven piston pump that pumps vapor refriger- ant 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 refrig- erant.

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.

Split 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.

Receiver

The component in a refrigeration system that stores liquid re- frigerant that is not being used by the system in low load condi- tions or when the system is shut down.

Service Valve

A manually operated valve in the refrigeration system that is used for various service operations 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 evaporator that controls the TXV. Inside the bulb is a charge that reacts to temperature and regulates the flow of refrigerant through the expansion valve.
