What is the difference between absorption chiller and adsorption chiller?
The main difference between adsorption chillers and absorption chillers is during the adsorption method the water is adsorbed onto a solid (the non-hazardous or corrosive silica gel) and in the absorption method the water is dissolved into a liquid (the corrosive lithium bromide).
What are two types of absorption chillers?
Single effect absorption chiller refers to chillers that have only one generator chamber. In contrast, the double effect absorption chiller concentrates its adsorbent solution in two stages. Once in a high-temperature generator and once in a low-temperature generator.
What is the working principle of adsorption chiller?
Both adsorption coolers and more-conventional compressor cooling units use a liquid refrigerant with a very low boiling point. In both devices, when the refrigerant boils and evaporates, it takes some heat away with it, providing cooling. (The effect is analogous to a human becoming cool by sweating.)
What is the primary disadvantage of absorption chillers when compared to compressive cycle chillers?
Two of the primary disadvantages of absorption chillers are their size and weight, and their requirement for larger cooling towers.
A review of the practically realized solid adsorption solar refrigeration cycles is presented. The cycles also have potentials for use as heat pumps.
