Refrigeration & heat exchange
vapor absorption cycle
Industrial machinery; Refrigeration & heat exchange
In an absorption refrigerator, a suitable combination of refrigerant and absorbent is used. The most common combinations are ammonia (refrigerant) and water (absorbent), and water (refrigerant) and ...
gas cycle
Industrial machinery; Refrigeration & heat exchange
When the working fluid is a gas that is compressed and expanded but doesn't change phase, the refrigeration cycle is called a gas cycle. Air is most often this working fluid. As there is no ...
heat exchanger
Industrial machinery; Refrigeration & heat exchange
A heat exchanger is a piece of equipment built for efficient heat transfer from one medium to another. The media may be separated by a solid wall, so that they never mix, or they may be in direct ...
tube diameter
Industrial machinery; Refrigeration & heat exchange
Using a small tube diameter makes the heat exchanger both economical and compact. However, it is more likely for the heat exchanger to foul up faster and the small size makes mechanical cleaning of ...
tube length
Industrial machinery; Refrigeration & heat exchange
Heat exchangers are usually cheaper when they have a smaller shell diameter and a long tube length. Thus, typically there is an aim to make the heat exchanger as long as physically possible whilst ...
tube pitch
Industrial machinery; Refrigeration & heat exchange
The tube pitch is the centre-centre distance of adjoining tubes. When designing the tubes, it is practical to ensure that the tube pitch is not less than 1.25 times the tubes' outside diameter. A ...
tube corrugation
Industrial machinery; Refrigeration & heat exchange
This type of tubes, mainly used for the inner tubes, increases the turbulence of the fluids and the effect is very important in the heat transfer giving a better performance.
