Chiller Installation and Service

Chillers can be thought of like the commercial version of a residential cooling system, and they are used for largely the same purposes, except on a bigger scale. The industrial-sized air-conditioning and process chillers used by commercial concerns require that a stream of water undergoes a temperature reduction before being pumped throughout a building to accomplish its cooling effect.

Much like the condenser unit of an air conditioner, there is a refrigeration cycle used by a chiller to transfer heat from the indoors to an external location. The most significant mechanical or operational difference between a chiller and a residential air-conditioning unit is that the air conditioner will directly interact with interior air, whereas a chiller simply cools the water, which is then distributed throughout the building.

Types of chillers

One of the ways of classifying chillers is by the method with which they transfer heat, which is done in one of two ways: water cooling and air cooling. An air-cooled chiller comes directly in contact with the outdoor air to accomplish heat rejection, while fans are used to create airflow within the unit itself. An air-cooled chiller still requires a water line to remove the indoor heat.

In the case of a water chiller, it requires a first water line for cooling distribution, and an additional water line for heat rejection and this water is then transferred to an outdoor cooling unit, which releases that heat. Sometimes chillers are also classified by the kind of compressor which is built into the unit, and these can be either centrifugal chillers, reciprocating chillers, or rotary-screw chillers.

Reasons for chiller replacement

There are a number of reasons why your commercial or industrial chiller might need replacement, prime among them the energy efficiency which you would gain by installing a newer model. The newest versions of chillers feature more automatic controls than those of the past, along with highly advanced compressors, which can save considerably on the amount of energy used during cooling.

Another good reason for replacing an existing chiller is that you’ve determined you have a size mismatch relative to the building load. If you’ve never had an assessment of your chiller setup, it would be a very good idea to do so, because there’s a fair chance that your chiller unit is not sized correctly for its operational load.

When there is such a size mismatch, it can very often lead to poor performance and poor energy utilization. A common misconception is that an over-sized chiller is much more desirable than an undersized unit or a right-sized unit, but this is simply not the case. Only a properly sized chiller
