SUMMARY:

An innovative technology that can collaborate to mitigate environmental problems and make energy consumption more efficient in air conditionig system is thermal energy storage (TES). The TES also helps to decouple the cooling production and the use of it. The main objective of this investigation is to develop a mathematical model that is able to obtain the thermal loads of the environment based on ABNT NBR 15220 and ABNT NBR 16401 standards, and simulate the operation of an air conditioning system integrated with TES, considering the direct consumption of the cold energy, the production for storage and the system working with the stored cold. It simulates the operation of refrigeration systems to evaluate the coefficient of performance of the refrigeration cycle and of refrigeration system, including the TES, during a year for three cities in different regions in Brazil: Fortaleza/CE, Brasília/DF and Belém/PA. In each city will verify the efficiency of two different refrigerant fluids, R410A and R1234yf. Based on the data obtained from the mathematical simulation model, perform a thermal, economic, and environmental impact analysis for Brazil.
