There are now several options for mfgs. of ADsorption chillers using either zeolite or silica gel adsorbent. These range from 5 tons to 400 tons currently and use hot water from 65 C to 90 C. Yes, zeolite best for lower temp. hot water and silica gel better for higher temp hot water input. It is best to not go over 90C input to current adsorption chiller technology or a condition occurs inside chambers that can damage adsorbent bed material, so do not use 100C for adsorption chillers. Future developments will include a steam fired ADsorption chiller and exhaust heat fired ADsorption chiller, but for now only hot water fired.
If anyone needs any further information about ADsorption chillers let me know...
