Experimental study demonstrates chilled water production via solar activated carbon and methanol adsorption, highlighting a sustainable cooling alternative.
Adsorption cooling systems have drawn a lot of attention in recent decades because they seem promise in terms of greenhouse gas emissions and ozone layer depletion issues. The system performance is greatly impacted by the operating conditions and the thermos physical characteristics of the refrigerant pair. Activated carbon (AC) research is vital for adsorption cooling systems. The limitations of solar adsorption refrigeration technology can be addressed by using ACF as an adsorbent. Higher adsorption capacity per unit kg of adsorbent and quicker adsorption/desorption times are possible with ACF. The effectiveness of adsorption cooling systems taking into account different refrigerant pairings has been thoroughly studied. The adsorbent is contained in collectors that are powered by a solar-powered flat plate. Methanol and activated carbon were used as the adsorbent and adsorbate pair for this investigation. The cooling device endured design, development, and testing. According to preliminary findings, cooled water is produced at 6 ˚C and 12 ˚C.
