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.
Experimental studies with test benches made in recent years:
- Experimental study of the aqueous solution of nitrates of lithium, sodium and potassium as the working fluid in water absorption chiller driven at high temperature
- Industrial optimization and control strategy of an absorption chiller using ammonia/lithium nitrate and dissipation by air
- Experimental characterization and modeling of an absorption chiller single / double effect H2O/LiBr operated at two temperatures for air conditioning in buildings
- Modeling of absorption cooling systems with solar concentration
- Modeling of absorption chillers of small power by solar-powered thermal or residual
- Advanced systems of micro-trigeneration with gas microturbines and absorption chillers for air dissipation
- Experimental study of the absorption and desorption processes of the ammonia-lithium nitrate in plate heat exchangers
- Study the process of boiling the ammonia/water mixture in plate heat exchangers
- Study of the absorption process with ammonia / water in a plate heat exchanger
- Test bench for the study of thermal waste energy recovery by cycling mechanical vapor compression with solution circuit.
Some elements usually tested:
- Absorbers
- Desorbers
- Heat exchangers
- Chillers
- Circuits of solution
