19. WORKING PAIRS

20. Working pairs
• Activated carbon pairs :-
Activated carbon pairs are proposed in this investigation because
1- they have a large surface area.
2- relatively low cost.
-There are several studies regarding adsorbent–adsorbate working pairs for
adsorption refrigeration systems, pointing their characteristics, performances,
advantages and disadvantages.

21. Working pairs and it’s adsorbent characteristics
1-Silica-gel–water

22. Working pairs and it’s adsorbent characteristics
2-Activated carbon–methanol
3-Activated carbon–ammonia pair
4-Activated carbon-R134a
