Training objectives
- The course of Thermotechnical Plants deals with the production, distribution and use of heating and cooling energy for the most common civil and industrial applications. In particular, the course deals with the heating and air conditioning systems for the various uses of the environments (civil large-scale - airports, hotels, recreational and large communities - health, clean rooms, industrial, food, livestock, etc .. ..), of the different fluids used (air, water, steam and diathermic oil), of the various systems and types of regulation and distribution of the heating and cooling energy and of the environment terminals. The course also deals with the start-up, balancing and testing of the various plants (TAB, testing, adjusting and balancing). Elements of electrical design will also be provided to service the thermo-technical systems. The main knowledge acquired will be the following: calculation methods of thermotechnical systems of all kinds and their functional and regulation characteristics. The main skills acquired will be the following: ability to design and commissioning large-scale thermotechnical plant systems for the civil and industrial sector
Prerequisites
- Basic knowledge in Applied Thermodynamics, Fluid dynamics and Heat Transfer.
Course programme
- 1.Basic konwlodge of Thermodynamics, fluid dynamics and heat exchange. 2. human body interaction with
external environment (confined or not). 2. Phenomena of contamination (physical, chemichal and microbiological) in different environments. 3. Theoretical approach: mass and energy balance for the civil and industrial applications both in steady and transient conditions. Choice of the thermotechinical system and heat transfer fluid. 4. The generation of thermal and cooling\ energy. Types of boilers for water, steam and diathermic oil, air and water cooled chillers, absorption chillers, cooling towers. Sizing and design and assembly criteria. 6. Piping and air ducts. Sizing and design and assembly criteria. Accessories (safety accessories, anchors, expansion compensators, insulation, cathodic protection, etc.). District heating and cooling systems. 6. Distribution of heating and cooling energy. Sizing and installation criteria. Heat exchangers, re-evaporators, condensation tanks, storage tanks. 7. The environment terminals. Selection and installation criteria. 8. Fuels. Transport, piping and storage systems. 9. Cogeneration and trigeneration plants. 10. Principles of regulation of thermotechnical systems. Flow and temperature regulation for air, water and steam. 10. Water treatment. Air filtration. 11. Balancing and testing of the plants. TAB procedures (testing, adjusting and balancing). Measurement methods and equipment. 12. Special applications. Buildings and large-scale civil systems - airports, hotels, industrial kitchens, recreational facilities and large communities -, hospital and operating rooms, cleanrooms, industrial applications, food insustries, livestock, etc ... 13. Basic knowlodge electrical systems for thermo-technical systems . Didactic methods
- Theoretical lessons and design exercises. During the lessons, the teaching material and the tables necessary for the design of the various components of the thermotechnical systems will be provided.
If possible, practical commissioning exercises will also be carried out at plants under construction. Learning assessment procedures
- At the end of the course there will be a written test focusing on the topics discussed during the course and on the design of a thermotechnical plant project. In the event of a positive verification, with a profit higher than 18/30, the candidate may opt for an oral integration of the exam at his choice in order to improve the grade itself.
