 Notes In many supermarket applications refrigerant gas from the discharge line or from the top
of the receiver is used for defrost. This method of defrost diverts a portion of the hot
gas or cool gas (from the top of the receiver) to the suction line and back through the
evaporator being defrosted. The gas condenses in the evaporator and flows in
reverse, through check valves, around the TEV and liquid line solenoid valve. Liquid
refrigerant then flows to the liquid header where it is distributed to evaporators not in
the defrost cycle.

In order for this reverse flow to occur, the pressure of the defrost
header must be greater than the pressure of the liquid header. The difference in
pressure is known as the defrost differential. Several methods are used to obtain the
defrost differential. The (O)LDR is designed to maintain a differential pressure between
the receiver and the liquid header. Sporlan liquid line differential valves have a
solenoid bypass feature that allows the valve to remain full open or modulate to
maintain a differential.
