Getu Haile-Michael Livres

The book addresses the inefficiencies of traditional supermarket refrigeration systems, highlighting issues like refrigerant losses and energy-intensive defrosting processes. It introduces innovative numerical models for cascade and secondary coolant systems, demonstrating potential energy savings of 17,500 to 170,000 kWh annually. These systems not only enhance efficiency but also minimize environmental impact by avoiding harmful refrigerants, appealing to supermarket owners. Additionally, it provides a comprehensive guide for designing and retrofitting refrigeration systems using the secondary coolant model.

This book provides first-hand information on the inner workings of the process, dabbed by the international press as the 'creeping coup' that brought the downfall of the legendary Emperor Haile Selassie of Ethiopia. Written by one of the members of the Planning Committee who helped overthrow the Emperor, the book provides first-hand information on what took place in this committee and the Derg at large, during this period. The information provided is of immense value to historians and anybody who wants to research this period in Ethiopian history.
