The general purpose of a refrigeration system is to cool and store food and thereby preserve its shelf life. Supermarkets routinely use this last concept.
Refrigeration is only a means to an end.
In most cases, that end is the preservation of foods. Refrigeration is often a significant steady use of year-round electricity since this equipment runs even when the building is unoccupied. Therefore, it is usually cost effective to install the most efficient refrigeration practical. Consequently, CSW's utility representatives work closely with consumers during the early planning stages to help consumers understand their options. They will be alert to consumer expansion needs and the potential replacement of old inefficient equipment with new, improved units.
