2. Carbon Dioxide in Supermarket Refrigeration
Abstract : This thesis theoretically and experimentally investigates different aspects of the application of CO2 in supermarket refrigeration. Theoretical analysis has been performed using computer simulation models developed to simulate CO2 indirect, NH3/CO2 cascade, CO2 trans-critical and direct expansion (DX) R404A systems. READ MORE

5. Combined Energy Systems Applied to Productive Sectors: The Case of Dairy Farms in Central Bolivia
Abstract : Most energy solutions in developing countries focus primarily on solving domestic energy demands of their growing populations without due consideration of sustainable development. On the other hand, in most of these countries, a segment of energy users that has not received enough attention from governments and institutions regarding appropriate energy solutions is the productive sector.
