Summary

A study was conducted in a bank branch in Marrakech, Morocco to explore substituting split Room Air Conditioners (RACs) with high-efficiency, low Global Warming Potential (GWP) refrigerant at an affordable cost. Due to COVID regulations, some weather data from 2020 was unavailable. A Shallow Neural Network was used to recover some of the lost on-site weather data from historical field tests and an open-source weather database, allowing us to make use of the incomplete data. In conclusion, using the predicted weather data, it was found that the new R-32 RACs installed in 2020 used 8 to 29% of the power consumed by the old R-22 RACs under the same ambient conditions in 2019. This was due to a higher indoor room temperature setting as the cold air was directed to occupants by an occupant sensor and a lower usage ratio by COVID regulation. Future work should update these findings with new measurements once the bank's operations return to normal following the easing of COVID regulations.
