This paper presents the techno‐economic assessment of different selected and proposed, CO 2 booster configurations for supermarket applications. The mathematical model has been developed for eight different configurations and, analyzed for year‐round operations in five selected major cities of India having different climatic conditions. The performance of the configurations is evaluated in terms of annual energy saving, seasonal energy efficiency ratio, life cycle cost, and additional investment recovery time(AIRT). Subsequently, the performance of the systems are compared with the Basic Booster System (BBS). The results show, 357.4 MWh of maximum AES, and 51.2% of enhancement in SEER, for BBS with both low and medium temperature‐flooded evaporator integrated with the modified evaporative cooler (BBSM‐LT + MT) configuration over BBS in Ahmedabad, India, compared to the selected cities in India. The economic analysis reveals that BBSM‐LT + MT configuration has minimum AIRT of 1.2 years for Ahmedabad, India compared to selected cities in India. Hence, the performance of BBSM‐LT + MT is better compared to other investigated configurations, for all the selected cities. The proposed configurations can be considered as suitable option for supermarket application in terms of energy, environment, and economy.
