2020-8-13 · A chiller is a machine that removes heat from a liquid via a vapor-compression, Adsorption refrigeration, or absorption refrigeration cycles. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream (such as air or process water). As a necessary by-product, refrigeration creates waste heat that must be exhausted to ambience, or for greater .

Usually absorption machines work with shell-and-tube heat exchangers, which are more expensive at small scales, as compared to ?n-andtube designs. The structural strength of parting sheets and headers is less important than halocarbon/NH3 systems because they only need to endure the vacuum pressure which is less than one atmosphere.

2012-9-24 · In a shell and tube heat exchanger, the conventional segment baffle geometry is largely responsible for higher fouling rates. Uneven velocity profiles, back-flows and eddies generated on the shell side of a segmentally-baffled heat exchanger results in higher fouling and shorter run lengths between periodic cleaning and maintenance of tube bundles.

To simplify the concept of a chiller you should compare it to a drinking fountain where you get cold "chilled" water. There are a variety of water chiller types (see Fig.2). Most commonly, they are absorption, centrifugal .
