Abstract
In face of greenhouse effect and growing energy demand, severe restrictions were imposed on the traditional vapour compression cycle, which promoted research for alternative refrigeration cycles. Adsorption cooling is a thermally driven system, which uses natural refrigerants (low or zero GWP and ODP) and requires little maintenance because of the low number of moving parts. Nevertheless, the COP and SCP of the cycle are too low to be economically viable. Improvements in various aspects are being made to make adsorption a competitive alternative. This work presents a review of the following solid adsorption working pairs: activated carbon-methanol, activated carbon-ammonia, zeolite-water and silica gel-water. It contains the operation temperature, applications, drawbacks and different types for each working pair. Equilibrium equations were presented with the coefficients of affinity for several types of working pairs.
