    Thermoeconomic optimization studies of the refrigeration systems using metaheuristic techniques
    (2023) Nagraj, Makkitaya Swarna
    Refrigeration systems play a crucial role in maintaining thermal comfort by removing excess heat from enclosed spaces. These systems are vital for various applications, from cooling buildings to preserving perishable goods. The primary goal is to provide a cooling load to the evaporator through chilled water to maintain a specific temperature within the enclosed space. Among the various refrigeration systems, the vapor compression refrigeration system (VCRS) stands as the most widespread choice due to its high coefficient of performance (COP). However, VCRS consumes a significant amount of electricity because of its compressor, contributing indirectly to substantial CO2 emissions. To address the issues of energy consumption and CO2 emissions, researchers have turned their attention to refrigeration systems driven by alternative low-grade energy sources, such as vapor absorption refrigeration systems (VARS) and vapor adsorption refrigeration systems. Unfortunately, these sorption technologies tend to suffer from lower efficiency compared to conventional VCRS.
