Industrial process chilling systems come with four main components: evaporator, throttle valve/ expansion valve, compressor and condenser. All these components demand a lot in terms of initial investment and the subsequent operating costs. In many industries, chillers are the single most energy cons[..]

The total number of heat pump , refrigeration and air conditioning systems in the world stands at 3 billion, according to the International Institute of Refrigeration. Their estimates show that the industry consumes 17% of the global electricity. This enormity has prompted manufacturers and other st[..]

Heat exchangers are totally necessary in the refrigeration cycle: as shown in the diagram below, two out of the four basic steps in the refrigerant cycle are heat exchangers! Their operation affects greatly to the overall plant efficiency, so their maintenance is very important. Heat exchangers, lik[..]

What is power quality? Power quality is not an easy term to define, as there are many factors that could be involved in the definition, but in broad terms power quality is usually related to following concepts:

Most of the industrial processes include the conduction of fluids or energy transfer. This is possible thanks to the centrifugal pumps which are the most popular turbomachinery. The growth and improvement of the industrial processes have been always linked to the improvements in the pumping equipmen[..]

An industrial chiller protects processing equipment despite costing a small fraction of most of these facilities. It also increases production, specifically enhancing accuracy and speed of production in food, beverage, and pharmaceutical among other industries. Therefore, it is a no brainer that the[..]

Any process that does work or uses energy produces heat, according to thermodynamics principles. We know that many systems release heat to the environment during their operations. This includes the refrigerator in your house. In district cooling plants, the amount of waste heat involved is so enormo[..]

It is now more than a century since ammonia first played a role in the refrigeration process. As an irreplaceable natural refrigerant, this refrigerant is now widely used in green buildings where it offers immense operational and environmental benefits. This is to add to the conventional and more po[..]

There is no argument about the advantages of chilled water systems in large commercial facilities. A chilled water refrigeration system offers many advantages, mainly in terms of energy efficiency and ease of maintenance. You can magnify these advantages for your facility by ensuring proper and cons[..]
