The aim of this project was to know the existing thermal loads in a refrigerator and their variation in time, and synthesize this knowledge, simplifying it wherever possible, to create a user-friendly calculation program. The program was designed in MATLAB and its fluid simulations are done in FLUENT. The results obtained were compared with experimental approximations and returned favourable results.
