Steam absorption chiller

<p>Here absorption chiller diagram his absorption cooling cycle relies on three basic principles:&nbsp;<strong>When a liquid is heated it boils (vaporizes) and when a gas is cooled it condenses</strong>.&nbsp;<strong>Lowering the pressure above a liquid reduces its boiling point</strong>.&nbsp;<strong>Heat flows from warmer to cooler surfaces</strong>. An absorption chiller is consisted of four main parts:&nbsp;<strong>generators, condensers, evaporators, and absorbs</strong>. We can model the absorption chiller by considering the energy balance in the four parts. Absorption chillers&nbsp;<strong>collect waste heat from other processes and equipment to drive thermodynamic processes that allows water to be chilled and distributed for HVAC needs</strong>. Absorption chillers do not use mechanical compressors, instead making use of the absorption refrigeration cycle. Accepted refrigerants for this application are:&nbsp;<strong>R-410A, R-404A, R-407C and R-134a</strong>&nbsp;are accepted on all chillers, except for those with scroll compressors. However the GWP of these refrigerants is high, thus their prices are increasing and availability is decreasing&nbsp;</p>
