The existence of particulates circulating
throughout the refrigerant-side of an
operating chiller or refrigeration system can
lead to a multitude of problems. The impact
may ultimately include reduced performance,
chiller degradation and/or complete shutdown
and failure. Chief among the identified
offenders include the liberation of rust and
residue from chiller piping and components
that adversely and profoundly impact the
operation of the system (see
Rust
Particulate). Another harmful source
of particulates that has a significant impact
involves the residual contaminants invariably
remaining after the performance of a Hermetic
Motor Burnout cleanup using traditional
methods.
Rust: The refrigerant-side of chillers and
refrigeration systems exposed to moisture (see
Wet Refrigerant) are susceptible to the
formation of rust on shells and piping. This
condition may lead to the formation of
significant particulate concentration as the
rust flakes off and is carried by the
refrigerant throughout the system. Ultimately,
this liberated rust will lead to the plugging
of system components including orifices,
distribution plates, oil filters and the
erosion of compressor blades leading to an
imbalance of the compressor.
Residue: Although, it is well known by
industry professionals that rust particulates
can be menacing to chiller tubing and system
components, what is not widely recognized is
the effect of natural residue buildup on
chiller piping and components that suddenly
becomes liberated into the circulating
refrigerant. Refrigeration systems,
particularly shipboard systems, have
experienced significant residue particulate
problems following conversions from CFC to HFC
refrigerants. A buildup of residue on the
chiller piping system commonly occurs over
time. Upon conversion from CFC to HFC
refrigerant, the residue invariably begins to
flake off and is carried by the refrigerant
throughout the system.
Rust and residue particulates will migrate to
tube surface and lodge in other system
components resulting in the reduction in
efficiency and capacity and may ultimately
lead to catastrophic results. Consequences may
also include the plugging of system components
including orifices, distribution plates and
oil filters.
Hudson has developed unique RefrigerantSide® Solutions that eliminate rust as well as the
stubborn residue formation and restore the
system to optimal performance.
