Comparative Study of Three Different Adsorbent-Adsorbate Working Pairs for a Waste Heat Driven Adsorption Air Conditioning System Based On Simulation

In a previous study, a laboratory prototype of a thermal-driven adsorption air conditioning system employing activated carbon as adsorbent and methanol as the refrigerant was successfully developed. The experimental results employing the prototype obtained a COP of 0.19 and cooling capacity Q of ar...
