dc.description.abstract | The LPA technology utilises a refrigerant pump in
the liquid line after the receiver to maintain a high enough
pressure differential across the expansion valve to
compensate for the pressure drop in long liquid lines. This
allows the condenser pressure to be varied in line with
variations in the ambient temperature leading to lower
discharge pressures during periods of low ambient
temperatures and lower compressor power consumption.
Operation at lower pressures also increases the refrigeration
capacity of the system enabling it to cope with increased load
demands. LPA can be applied to new refrigeration plant and
as a retrofit to existing plant. LPA also enables the use of
liquid injection into the discharge line of the compressor
which de-superheats the refrigerant vapour before entering
the condenser. This increases the capacity of the condenser
which in turn enables operation of the plant at lower
condensing temperatures. This paper considers the
application of a LPA and liquid injection to a cold store
refrigeration system. The analysis has shown that more than
10% energy saving over and above the savings that can be
achieved with floating head pressure, can be achieved by
adopting the use of LPA in conjunction with liquid injection. | en_US |
