The presence of oil in the
refrigerant of operating chillers or
refrigeration systems is certainly expected.
Oil accumulates in refrigerant primarily due
to oil migration from the compressor. This is
especially true at the end of an overhaul
period, usually about four years, when oil
starts leaking into the refrigerant at a
relatively high rate.
Although, the presence of oil at specific
levels may actually enhance performance in
some systems, excessive oil buildup in the
evaporator, particularly with the new enhanced
tube designs, can adversely affect chiller
performance and energy efficiency. Excess oil
may result in a significant reduction of
capacity; efficiency and heat transfer with
resultant increased energy consumption.
Hudson has developed both online, i.e., while
the chiller continues to operate, and offline
RefrigerantSide® Solutions that effectively
eliminate oil logging, restore system
efficiency and regain optimum capacity.
