In recent years, sorption processes are increasingly gaining attention in the field of TES (thermal energy storage), owing to their advantages of high storage density and no significant heat loss during storage process. In this paper, a novel three-phase sorption cycle is proposed and evaluated...

Adsorption refrigeration and heat pump systems have been considered as important means for the efficient use of low-grade thermal energy of 60–150°C. Sorption systems are merely thermodynamic systems based on heat exchangers, and therefore a good design to optimize heat and mass transfer with...

A compact silica gel-water adsorption chiller without vacuum valves was manufactured and experimentally studied. This chiller contains two adsorption/desorption chambers and one chilled water tank. Each adsorption/desorption chamber consists of one adsorber, one condenser and one evaporator. The...

An adsorption cooling machine with LiCl/Silica gel–methanol was designed and tested, which can work for air conditioning and cold storage. The machine can be driven by low temperature heat source, such as solar energy and industrial waste heat. The composite adsorbent of LiCl/Silica gel has...

One two-phase thermo-syphon silica gel-water solar adsorption chiller and LiBr-H2O absorption chiller with new medium CPC (Compound Parabolic Concentrator) solar collectors were investigated. The reliability of adsorption chiller can be improved, because there is only one vacuum valve in this...

As a type of traditional cycle for electricity generation, the main limitation of the Rankine cycle is the endothermic process for the evaporation (e) of water (w), which does not always fit very well with the trend of the heat source. The Kalina cycle can make up the efficiency loss by using a...
