Abstract
The high cost of electricity has done that the air condition sector search for alternatives to produce coldefficiently. It is a necessity, especially in Brazil, where 17% of the total electricity consume is due air condition systems.This work presents a comparative analysis of conventional and an air conditioning with thermal storage system. Thesystems are design for cooling an office considering the climate of Belo Horizonte, Brazil. The refrigerant chosen was theR410A due availability of commercial components. In order to evaluate the performance of the air conditioner with andwithout a thermal storage a quasi-steady-state model was developed using the Equation Engineering Solver (EES). Thesimulations was made considering the climate of Belo Horizonte, Brazil using weather data obtained from June of 2019to May of 2020. The results show that the use of thermal storage increases the average COP in 6% and cooling capacityin 1.7%, reduces the number of running hours in 2% but increase the energy consumption in 42%.
