The refrigeration industry has expanded and intensified research into low GWP refrigerants to reduce environmental impact and to improve performance of air conditioning and refrigeration components in general. The need to the search for new soft drinks demands performance data and properties that represent an important issue for more detailed studies. The replacement of the R-410A is not an easy task, since it has characteristics such as good transport of thermal properties and high volumetric capacity of refrigeration. The AHRI, Air-Conditioning, Heating, and Refrigeration Institute, report, the source of our study, investigates this substitution by operating a water chiller originally loaded with R-410A and subsequently replaced by R-32, a low GWP refrigerant. For the AHRI tests, thermocouples and pressure sensors were initially installed at the inlet and outlet of the system components, as well as an electromagnetic flow meter to measure the volumetric water flow, the data of which are set forth below. The closed thermodynamic cycle, the respective P-h curves and the mathematical model were reproduced in the present work by a computer program, EES, which provides fluid property. According to the AHRI report, the tests were conducted with some pre-set parameters such as mass water flow and discharge temperature, for safety reasons. After obtaining the energy balance, we will make an analysis based on the design of the exchangers, comparing the refrigerant fluids.
