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...

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...

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...

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...

Rotary desiccant wheel cooling system operates on the principle of adsorption dehumidification and evaporative cooling. The system adopts natural substance as working fluid and can be driven by low grade thermal energy such as solar energy. Due to these merits, solar powered rotary desiccant...
