Silica gel is a synthetic, highly porous solid with a strong affinity for water vapor. It is crushed to a specific grain size. Grains are filled with microscopic pores that are slightly larger than water molecules. By changing the silica gel temperature, it can be made to adsorb or desorb water vapor at different pressures. Inside the chiller, cool silica gel adsorbs water at very low pressure. It is then heated to release water vapor at a higher pressure. “Hot Rod” Silica Gel This temperature swing adsorption cycle enables refrigerant at low pressure to move to a higher pressure, thus creating a cooling effect.

Step 1: Adsorption:

From the Evaporator Water Vapor (0.1 psia) Step 1: Adsorption Silica gel 85⁰F 95⁰F Hot Water The dry silica gel is still packed in the same radiator. It does not move. Cooling tower water runs through the radiator. The cool, dry gel adsorbs water vapor from a cold evaporator. The evaporating water refrigerant provides the cooling effect.

Step 2: Regeneration:

Step 2: Regeneration Silica gel 194⁰F 182⁰F Hot Water Silica gel beads are packed between fins in a radiator coil. Hot water runs through the radiator. Heat is applied in a vacuum. The silica gel dries out. The vapor is sent to a water-cooled condenser where it is captured and re-used. To the Condenser Water Vapor (0.8 psia)

News: Power Partners Teams with DOE's Pacific Northwest National Laboratory 7/15/2010 …on a $2.54 million research program to test new sorbents and refrigerants in a type of air conditioning unit that runs on waste heat or heat from solar thermal collectors. During the three-year program, the team will design, assemble and test an adsorption chiller that takes advantage of PNNL's metal-organic heat carrier technology. The goal is to utilize PNNL's advanced materials and develop adsorption chillers that are smaller, more efficient and affordable enough to be used more frequently in commercial buildings. Power Partners will lead engineering and testing efforts as the project advances from a bench-scale prototype to a 5-ton cooling capacity demonstration unit, utilizing its state-of-the-art test facility.
