Absorption Chillers
San Diego Chiller Service has experienced technicians to effectively maintain all types of absorption chillers. Our technicians have training on numerous brands of chillers and we have active accounts at customer sites with every type of absorption chiller, direct fired and indirect fired using either steam, hot water or exhaust gases.
Centrifugal
Chillers
This is the key component in the larger commercial and industrial HVAC
systems. While many service companies will offer to include the centrifugal
chiller in their scope of work they lack the experience to provide the
best service. San Diego Chiller Service has technicians with extensive
training and experience on all of the centrifugal chiller types.
Reciprocating,
Screw, and Scroll Chillers
There are numerous types of compressor packages. Each type requires special
knowledge of the characteristics that are associated with it. The reciprocating
compressor requires the most periodic service as it has many moving parts
that can wear over time. The scroll
type is the newest type of compressor with very few moving parts, but
is limited in its capacity control features. The screw
compressor uses the principle of two meshing helical rotors to capture
and compress a fixed volume of gas. This type of compressor must be properly
applied to match the system that it will operate in.
Package Units
A package unit is a complete assembly of all the components in a refrigeration
cycle. With the exception of the absorption chiller all other chiller
packages will have some type of compressor. There will also be an evaporator,
condenser, and a metering device. Each of the components in a package
will have its own maintenance requirements to keep the package running
efficiently.
Shell and Tube
Vessels
The heat transfer that takes place in a chiller package is done in the
shell and tube heat exchangers. To maximize the efficiency of the package
and to prolong the life of the vessels, periodic service must be done
on these critical components of the chiller package. Eddy current testing,
epoxy coating, brushing tubes, and acid washing are all part of chiller
maintenance.
Cooling
Towers
Cooling towers, sometimes called condensers, are the last component in
the heat transfer cycle. Energy, in the form of heat, is captured by the
refrigerant from the cooling load and rejected to the atmosphere by this
component. Condensers will use water and/or air to assist in the release
of this energy to the atmosphere. A lot of factors come into play for
the effective operation of the cooling tower. These would include ambient
temperature, relative humidity, and prevailing wind direction, among others.
Effectively maintaining a cooling tower requires water treatment, general
house keeping of the sump and nozzles, along with other maintenance requirements
on the mechanical components.
