The goal of the secondary refrigeration system project was to design and build a secondary refrigeration loop to interface with an existing primary refrigeration loop for the testing and research of microencapsulated phase change material, as well as an educational tool for students interested in refrigeration. The aim of this report is to discuss and explain the final version of the design, the testing methods, results, conclusion, and any future recommendations. The wind tunnel is operational, reaching an average maximum air velocity close to what the group had aimed for. The heaters were able to heat the air to the desired range. Piping and most components and instrumentation have been connected and mounted. LabVIEW has been set up to read the outputs of the instruments. Unfortunately, the steam generator has not been mounted and the system has not been charged due to time constraints. Since much time was spent fixing the primary loop to an operational state, it is recommended that future groups working on the existing refrigeration loops ensure that they are working prior to the start of a new project. Overall, the client who requested this system is satisfied with the outcome, despite not meeting certain design criteria.
