057907 - HVAC&R SYSTEMS LAB
The course deals with laboratory tests of components and systems largely used in the heating, air conditioning and refrigeration (HVAC&R) field. The course aims to provide a detailed knowledge of some HVAC&R components and the methods to measure and evaluate their performance adequately.
Risultati di apprendimento attesi
In terms of acquired knowledge and understanding, students will be able to:
Describe the analysed technologies related to HVAC&R systems.
Discuss lab equipment (test rig layout, instrumentation, etc.) and test procedures.
Concerning the ability to apply the acquired knowledge and understanding, according to research objectives students will be able to:
Design and assess a test rig setup.
Design and assess lab test procedures.
Carry out experimental tests, following operational and safety procedures.
Collect and classify experimental data.
Interpret and verify the quality of the obtained results.
Students will improve their communication skills, being able to select relevant information, rearrange data and results, to present the main elements of the work effectively.
The course is divided into theoretical lectures and experimental activities carried out in the laboratory. During the theoretical lectures, the basic knowledge about the operating principles of the components/systems analysed in lab tests is revised. During the lab experiments, the focus is on the correct design of the experimental activity (measurement circuit, testing procedure, etc...), on the interpretation of the observed phenomena, and on the critical assessment of the experimental results.
Three or four experimental activities will be carried out during the course. They will be chosen among the following:
Heat pump working with low GWP refrigerant.
Heat pump working with carbon dioxide.
Heat exchanger (refrigerant – water).
Heat exchanger (PCM in plate heat exchanger).
Heat exchanger (air-to-air, static or rotative).
Direct or Indirect Evaporative Cooling.
Thermochemical heat storage.
The course topics are dealt with through introductory lectures and lab activities. Students will be involved in ongoing experimental lab research activities and specifically-designed lab tests at the Refrigeration Lab and Adsorption Lab of the Department of Energy.
In the course, the working principles and the typical performance of technologies typical of the HVAC&R sector are presented and experimentally analysed. Widespread implementation of these technologies may bring substantial benefits from the energy, economic and environmental point of view. The experimental activities are performed on lab-scale components/systems, but they can be easily scaled up and adapted to the domestic, industrial or city level.
Knowledge of thermodynamics and heat transfer is required as per the background in Energy Engineering.
Modalità di valutazione
Students are asked to prepare a report on the lab activities and to discuss it through an oral presentation.
The report may be prepared in team and aims to evaluate students’ understanding of identification and application of correct methods and procedures as well as their ability to examine and interpret data.
The oral presentation aims to evaluate the ability to select relevant information and present new experimental data to a scientific panel.
