The Research Group in Applied Thermal Engineering has an area of 140 m2 for installation of test benches for processes of heat and mass transfer in absorption and desorption processes. These facilities are designed, assembled and tested by the research group. The aim of this type of facility is the study of various processes of interest in absorption refrigeration technologies, such as the absorption and desorption from the viewpoint of heat transfer material. The main purpose of these facilities is the transfer of technology, either through internal research (Ph.D. dissertations, master, etc.), as well as external service companies, institutions, etc. Some elements usually tested: – Absorbers – Desorbers – Heat exchangers – Chillers – Circuits of solution |
