Syllabus
Prerequisites: Fundamentals of thermodynamics (laws, inverse cycles, fluids), fluid dynamics, heat transfer and machinery.
Target skills and knowledge: The course:
-provides skills that can be used directly in the design, management and optimization of refrigeration machines and heat pumps;
-wants to make the students aware of the technological evolution of the sector, driven by the replacement processes of refrigerants and energy efficiency requirements;
-intends to provide the ability to analyze and compare different solutions for the production of refrigeration, both in terms of cycle optimization, fluids and components;
-intends to provide the ability to use software tools such as a refrigerant database.
Examination methods: The exam consists of a theory test with open questions.
Students must bring the laboratory report at the exam.
For those wishing to carry out the optional project, the project report must also be delivered at the exam.
Assessment criteria: -Evaluation of the level of learning,
-ability to explain concepts and procedures studied in the course,
-skills of applying knowledge to the laboratory exercise,
-quality of laboratory report,
-ability to develop a software to predict the performance of a refrigerating machine (optional).
Course unit contents: The vapor compression cycles: efficiency analysis and methods to reduce the losses.
The refrigerants: functional features, safety and environmental compatibility.
The refrigerant circuit of the vapor compression and its components:
-volumetric compressors (reciprocating and rotary of various types) and centrifugal compressors;
-air and water condensers;
-expansion devices (control level valves, thermostatic expansion valves, capillary tubes);
-flooded evaporators and dry expansion evaporators;
-control bodies, security devices and accessories.
Technology of two-stage plants.
Technology of heat pumps.
Refrigeration systems with CO2 as refrigerant: technology and applications.
Absorption refrigerating cycles.
Use of Refprop database (NIST) from Excel and Matlab.
Planned learning activities and teaching methods: -Theory lectures.
-Numerical examples.
-Laboratory for the use of Refprop database.
-Technical visits to industry.
-Development of a predicting software of a refrigerating/heat pump equipment (optional)
