Absorption of Ammonia-Water and CO2-NH3-H2O Mixture in Mini-Channel Heat Exchangers

The energy consumption in the industry field is considerable. Saving energy has great potential in many industrial processes. For example, heat recovery from the spent cooling water can be achieved by applying heat pump technology, and the recovered heat can be used for district heating. Previous study indicates that the compression-resorption...

Absorption of CO₂-NH₃-H₂O mixture in mini-channel heat exchangers

Compression resorption heat pumps (CRHP) are a promising option to upgrade waste heat from industry. Alternative working fluids can further improve the efficiency of CRHP. The ternary mixture NH3-CO2-H2O has been identified as a promising working fluid for CRHP and has the potential to further enhance the coefficient of performance (COP) of the...
