Objectives
THIS COURSE INTRODUCES THE FUNDAMENTAL PRINCIPLES OF THERMODYNAMICS HAVING IN MIND TO APPLY THEM TO FEATURE REFRIGERATION AND HEATING SYSTEMS. MOREOVER, THE OPTIMISATION OF THESE SYSTEMS FOR THE PURPOSE OF ENERGY EFFICIENCY IS INTRODUCED. THUS, THE COURSE OBJECTIVE IS TO PROVIDE THE KNOWLEDGE OF THE BASIC YET CRITICAL CONCEPTS CONCERNING THERMODYNAMICS AND ENVIRONMENTAL CONVERSION SYSTEMS. HEATING PLANTS ARE EXPLORED IN THE FRAMEWORK OF THE ACTUAL LAWS PANORAMA AND LIGHT IS GIVEN TO ECONOMIC, ARCHITECTURAL, "COMFORT" AND "ENERGY SAVING" ASPECTS.FURTHER AND UPDATED INFORMATION CAN BE FOUND BY LINKING TO THE URL:HTTPS://WWW.RINOCUCCURULLO.COM
Prerequisites
FOR THE SUCCESSFUL ACHIEVEMENT OF THE OBJECTIVES, THE KNOWLEDGE OF THE BASIC NOTIONS AS GIVEN IN THE FIRST YEAR COURSES OF MATHEMATICS AND PHYSICS, IS REQUIRED.

RADIATIVE HEAT TRANSFER (18) - THERMAL RADIATION: SPECTRAL AND DIRECTIONAL FEATURES. INTENSITY OF THE RADIATION FOR CALCULATING THE RADIATIVE HEAT FLUXES. BLACKBODY RADIATION. RADIATIVE CHARACTERISTICS OF OPAQUE SURFACES: EMISSION - ABSORPTION - REFLECTION, DEFINITIONS AND MODELS. RELATIONSHIP BETWEEN THE EMISSION, ABSORPTION AND REFLECTION. SPECIAL SURFACES. HEAT TRANSFER BETWEEN DIFFUSE GRAY SURFACES.
Teaching Methods
DURING THE COURSE LESSONS AND EXERCISES ARE PROVIDED IN THE CLASSROOM. SELECTED EXERCISES ARE ASSIGNED TO THE STUDENTS IN ORDER TO IMPROVE THE KNOWLEDGE OF THERMODYNAMICS, ENERGY CONVERSION SYSTEMS AND HEAT TRANSFER
Verification of learning
THE ACHIEVEMENT OF THE PREFIXED OBJECTIVES WILL BE REALIZED BY WRITTEN TEST AND ORAL INTERVIEW. THE LATTER IS TO BE HELD NECESSARILY IN THE SAME SESSION IN WHICH THE WRITTEN TEST IS PASSED AND IS TYPICALLY SCHEDULED SEVEN DAYS AFTER THE WRITTEN TEST. IN PARTICULAR, IT IS AIMED TO EVALUATE THE CAPABILITY OF THE STUDENT IN APPROACHING, WITH CRITICAL SENSE AND MATURITY, PROBLEMS TYPICAL OF APPLIED THERMODYNAMICS. WRITTEN TESTS MAY INCLUDE QUESTIONS OPEN AND STRUCTURED SEMI-STRUCTURED TESTS IN ADDITION TO VARIOUS TYPES OF EXERCISES.
