An activated carbon–methanol adsorption refrigeration system is tested, in which the performances of a granular bed and a solidified bed are compared. Results are presented and the effects of heat and mass transfer are analyzed. It is proved that the coefficient of performance of refrigeration...

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 novel double heat pipe type adsorber, which uses compound adsorbent of CaCl2 and expanded graphite to improve the adsorption performance, is designed. The double heat pipes are integrated into the adsorbers in order to solve the problem of the corrosion between seawater and the steel adsorber...

Adsorption heat pump and refrigeration systems are noiseless, non-corrosive and environment friendly. For these reasons the research activities in this sector are still increasing to solve the crucial points that make these systems not yet ready to compete with the well-known vapor compression...

Modern large and fast ocean fishing vessels include mechanical refrigeration, but all of them consume precious fuel or electricity to achieve refrigeration. Fishing vessels with tonnage at about 100 tons cannot attach compressor-icemaker onboard because of their small horsepower of diesel...

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...
