The thesis analyzes the functioning of a reverse cycle and its application in refrigeration systems, with particular attention to the performance comparison between two cold rooms. After a theoretical description of the reverse cycle and its role in refrigeration, the structure, functioning and main fields of use of cold rooms are explored in depth. A list of the most common construction materials is also presented, with a focus on their insulating properties. A section is dedicated to refrigerant gases, including their historical evolution and main characteristics.

La tesi analizza il funzionamento di un ciclo inverso e la sua applicazione nei sistemi di refrigerazione, con particolare attenzione al confronto prestazionale tra due celle frigorifere. Dopo una descrizione teorica del ciclo inverso e del suo ruolo nella refrigerazione, si approfondiscono la struttura, il funzionamento e i principali campi di utilizzo delle celle frigorifere. Viene inoltre presentato un elenco dei materiali costruttivi più comuni, con un focus sulle loro proprietà isolanti. Una sezione è dedicata ai gas refrigeranti, includendone l’evoluzione storica e le caratteristiche principali. Infine, la parte di calcolo confronta le due celle dal punto di vista dell’isolamento termico e dell’efficienza energetica, sulla base di dati ipotizzati, per identificare la soluzione più performante.

Abstract
The thesis analyzes the functioning of a reverse cycle and its application in refrigeration systems, with particular attention to the performance comparison between two cold rooms. After a theoretical description of the reverse cycle and its role in refrigeration, the structure, functioning and main fields of use of cold rooms are explored in depth. A list of the most common construction materials is also presented, with a focus on their insulating properties. A section is dedicated to refrigerant gases, including their historical evolution and main characteristics. Finally, the calculation part compares the two cells from the point of view of thermal insulation and energy efficiency, based on hypothesized data, to identify the best performing solution.| File | Dimensione | Formato | |
