A thermochemical resorption refrigeration system was designed and two types of application were investigated: (1) cold … storage and (2) long-distance refrigeration. Manganese chloride and ammonium chloride were used as high-temperature salt (HTS … (140–170°C) and refrigeration temperature (−15 to 5°C). The COP obtained at these conditions varied between 0.20 and 0 …

The entropy generation analysis of heat and mass transfer in a slit microchannel is performed in this study. The flow is assumed to be due to a combination of the electroosmotic body force and the pressure gradient. A fully developed flow with uniform flux at the surface is considered in the...

An increased interest in absorption chillers has been observed [1] because these systems can utilize solar, geothermal and biomass energy sources, but also because they are quiet, vibration-free, require little maintenance and are ecological [2]. Instead of a compressor system, which uses...
