Theoretical Analysis of Isentropic and Alternative Refrigerant Based Cooling System and Low Carbon Economy

The current trend of energy supply and its uses are very unstable economically, socially and environmentally. Greenhouse gas emissions are continuing to increase, and it will affect the environment globally. The scope of alternative refrigeration system like vapour absorption (VARS), vapour adsorption and ejector cooling can play significant role in the modern industry with low carbon emission. The experimental setup of 03 Ton of cooling (TR) of dry compression vapour compression refrigeration (VCRS) has been evaluated and compared with single-stage of LiBr-H₂O-based VARS cooling system. The operating condition of condenser, evaporator temperature and pressure have been considered for performance analysis of both systems. The higher value of condenser temperature not suitable for efficient cooling and also decreases the energy performance ratio (EPR or COP) of system. The R134a is commercially useful eco-friendly refrigerant but applicable in VCRS (Energy consumption by VCRS is much more than VARS). The employment of VARS have tremendous potential for space cooling and water chilling application at same range of VCRS operating temperature of condenser with low-grade energy source or solar energy utilization. VARS is low carbon emission and non-toxic technology and able to map decarbonize economy for industrial sector.
