Abstract
In recent years, adsorption technology-based cooling systems are being increasingly examined as a sustainable technological alternative for fulfilling the fast-growing cooling demands due to their potential to employ low-grade heat energy and environmentally benign working fluid. The present study is an attempt to evaluate the cooling assessment of a single-stage adsorption cooling system coupled with a bioenergy heating unit. The maximal, minimal, and optimal limits of heat source temperature are evaluated for two different climate conditions. The Dubinin-Astakhov isotherm model is adopted to analyze the adsorption uptake of ethanol refrigerant over biomass-derived activated carbon sorbents. The MATLAB R2021b platform is used to numerically investigate the effects of various operating parameters such as evaporator temperature, ambient temperature, and regeneration temperatures on the coefficient of performance, cooling power, and mass of adsorbent to combustion fuel ratio. The optimal regeneration temperature for WPT AC is found to be lesser (92 °C) than that of M AC (94 °C) at ambient temperature of 32 °C. Moreover, the theoretical results demonstrate that both adsorbents with ethanol as refrigerant require an equal amount of minimal and maximal regeneration temperature of corresponding to ambient temperature of 38 °C. Overall, the methodology described in the present work is quite valuable for designing and implementing the bioenergy-powered green cooling system.
