How can concentration in terms of rich and poor be affected by adding nanoparticles to LiBr-Water?
Dear Cenker Aktemur,
Actually,
In refrigeration systems, nanolubricant improves tribological characteristics improving compressor performance; nanorefrigerant improves thermo-physical properties, improving refrigerating effect. Presence of nanoparticles enhances solubility between oil & refrigerant and returns more oil back to the compressor.
Hope this following link will help you to enhance information related to that question.

Thanks.
The heat transfer in binary nanofluids are enhanced more than that in base fluid and the highest absorption mass flux is observed by adding nanoparticles. The effectiveness of the nanofluid becomes higher than that with the base fluid
when the Reynolds number and concentration are lower and when the temperature and pressure are higher.
Gamal B. Abdelaziz tnx for comments, but I need equations to integrate with absorption refrigeration system
Zia Hameed tnx for comments, but I need equations to integrate with absorption refrigeration system
Adding nano fluid may increas the heat transfer and make th absorption unit work better but may be the circulation wuold be low
Dear Kenkar,
In diffusion absorption coolers regarding to the heat performance of the system, ammonia/water couple with alumina (Al2O3) particles in nano-size can be a better option. It can provide better absorption of heat from the generator and faster evaporation of the cooler from the cooling/absorption fluid. Considering the effect of fluids containing nanoparticles the connection units of the heat transfer in the system operation time of the system might be reduced due to shorter heat transfer periods.
