Functioning of Water Cooled Chiller & Water Cooled Air Chiller

It's impossible to imagine our life throughout the summertime without machines designed for cooling our working and home environments. Various kinds of air chillers have been invented and several companies are still polishing ideas to make much more efficient and expedient refrigeration devices. When speaking about air cooled chillers it must be noted that they're considered to be less energy efficient than those operating by water, however, they aren't as pricey as water cooled chiller and more affordable to maintain. And on the other hand air cooled chillers are more energy efficient than traditional freon powered refrigeration equipment, thus, all of these advantages make them the common choice in many companies and industries.

The main aim of such chillers is to cool the surrounding air thus usually these refrigeration devices serve the larger scale industrial and commercial purposes. As a point of interest, In spite of the fact that air cooled chillers function by air, it's absolutely incorrect to think that they don't use water. In many cases, water is part of the integral system, but it's not used to soak up superfluous heat from the units closed system. The structure of a chiller that works by air is the following way: it includes an evaporator with a certain liquid substance used for refrigeration, tubes full of water surround the items supposed to be chilled, then a compressor increases the pressure and the apparatus forms a condensing vapor that in turn, connects back to the evaporator.

The process of cooling starts in the evaporator, its liquid coolant spreads out cold to the tubes full of water. The chilled water is pumped through an area where it absorbs heat from this area thus chilling them. After that, the water in the tubes finally reaches a high temperature that becomes enough to radiate the heat back into the evaporator, where the refrigerant causes the heated water to turn into vapour. It then passes through a special tube in the compressor where the vapour is compressed into a smaller space, thus, put under even higher pressure. Then the condenser picks up the baton and lets the pumped vaporized refrigerant through. The condenser has a set of special portions of the entire device called air cooled vanes, just comparable to those of a car's radiator. The vapour condenses back into a liquid that gives its heat into the surrounding air. The liquid goes back into the evaporator where the production cycle is restarted again.
