“…The mass recovery cycle increases the amount of refrigerant circulating, it makes a bigger difference between the adsorbed quantity on the adsorption side and the desorption side, and it is expected that the SCP can be improved. AKAHIRA et al [14] presented the equilibrium analysis result with mass recovery cycle using silica-gel/water working pair. It is present that the mass recovery cycle shows more performance improvement in the low-temperature heat source region from 60℃ to 70℃.…”

In order to utilize the adsorption chiller or heat pump as a next-generation air conditioning system, several issues still remain, such as performance improvement, miniaturization, and cost reduction. It is known that the activated carbon-freon refrigerant pair has a relatively lower coefficient of performance (COP) than the silica gel-water or freon refrigerant pair and zeolite-water pair. However, there is a possibility to contribute minimize the adsorption heat pump system utilizing Freon refrigerant since it works in high-pressure regions and has a high saturation vapor density. Therefore, evaluating and improving the performance of Freon refrigerant is an important future task.
