Ammonia/ionic liquid based double-effect vapor absorption refrigeration cycles driven by waste heat for cooling in fishing vessels

To use high-temperature waste heat generated by diesel engines for onboard refrigeration of fishing vessels, an ammonia-based double-effect vapor absorption refrigeration cycle is proposed. Non-volatile ionic liquids are applied as absorbents in the double-effect absorption system. In comparison to systems using ammonia/water fluid, the...

Advanced NH3 based absorption refrigeration cycles: Modelling of the ionic liquid based double-effect cycles

Absorption refrigeration cycles are energy saving as they can be driven by waste heat instead of electricity. By doing so, they reduce the use of fossil fuels, resulting in a reduction of emissions. However, many challenges exist for the traditional working fluids of the cycle, such as the crystallization problem of the water-lithium bromide...
