Evaporator - Types Of Evaporators

The evaporator is kind of heat transfer apparatuses where the heat transfer is done by forced convection or natural convection. And it’s an important component of refrigeration system and air conditioning system. Evaporation process is rejection of water  (or other liquids) by concentrating the solution. The required time for this process can by shortened by increasing the surface area, the solution is exposed to it, or by exposing  the solution to heating to a higher  temperature. How does evaporator work ? For a basic refrigerant cycle shown in figure 1, which is used in many forms in all common air conditioning, refrigeration, heat pump applications. It uses a proper refrigerant that has the capability to change...

What Is An Absorption Chiller ?

What is An Absorption Chiller ? An Absorption Chiller is a machine uses a heat source to generate chilled water rather than electrical source that is used in vapor compression cycle. It’s an attractive idea to produce chilled water with heat. As the same in vapor compression cycle, absorption cycle achieve removing heat using the evaporation of a refrigerant at low pressure and the ejection of heat using the condensation the refrigerant at high pressure. The major difference between  a vapor compression system and an absorption chiller is that a vapor compression system using a compressor to make the pressure difference required to circulate the refrigerant while the absorption chiller using heat. The absorption...
