Industrial refrigeration equipment, chillers

Refrigeration and air-conditioning absorb about 15% of the UK's electrical generation capacity and it is not always appreciated that refrigeration technology is essential to our modern way of life. Without it, distribution of food to urban areas may not be possible. In a typical office, air conditioning can account for over 30% of annual electricity consumption, yet who cares about checking the system to find out if it is working efficiently?

Refrigeration equipment

Reducing the environmental impact of cooling whilst at the same time maintaining and expanding expectations is the driver of many of the developments which have been made since the last edition. Aimed at students, and professionals in other disciplines, not too theoretical but with sufficient depth to give an understanding of the issues, this project takes the reader from the fundamentals, through to system design, applications, contract specifications and maintenance. Almost every category could be expanded into a project in itself and references are provided to assist those wishing to delve deeper. Standards and legislation are subject to change and readers are recommended to consult the Institute of Refrigeration website for the latest developments.

Refrigeration is the action of cooling, and in practice this requires removal of heat and discarding it at a higher temperature. Refrigeration is therefore the science of moving heat from low temperature to high temperature. In addition to chilling and freezing applications, refrigeration technology is applied in air conditioning and heat pumps, which therefore fall within the scope of this project. The fundamental principles are those of physics and thermodynamics, and these principles, which are relevant to all applications.

Reconditioned Chillers and Equipment

• Air and Water-cooled chillers
• Capable of reaching -100 degrees F, leaving process fluids
• Suited for heavy industrial applications
• Designed and manufactured according to customer’s individual needs

One characteristic of industrial refrigeration is the temperature range it embraces. While evaporating temperatures may be as high as 15°C (60°F), the range extends down to about -60° or -70°C (-76° or -94°F). At temperatures much lower than about -70°C (-94°F) another industry called cryogenics takes over, producing and using liquefied natural gas, liquid chiller, nitrogen, liquid oxygen, and other low-temperature substances. If industrial refrigeration were described as the refrigeration that occurs in the food, chemical, and process industries, then probably two- thirds of the applications would be covered. Another significant application exists in the manufacturing industry and in laboratories where special conditions, especially low temperatures, must be maintained. While the low temperature range may be the best single means of characterizing industrial refrigeration, some industrial heat pumping applications that reject heat at much higher temperatures than ambient could also be called industrial refrigeration.
