Salamanca, Gto., September 19, 2016.- The Mexican Society of Thermodynamic A.C. and the Technological Institute of Durango gave the National Award of Doctoral Thesis in the area of Thermodynamics to the professor at the University of Guanajuato (UG), Vicente Pérez García.
With his project "Application of CO2 to produce cold: dimensioning and construction of a trans critical installation," the Engineering professor of Mechanical Engineering from Campus Irapuato-Salamanca, achieved the distinction of best doctoral thesis presented during 2014 and 2015.
The project consists in dimensioning an installation to produce cold in a medium refrigeration level, with temperatures inside the room from 0° to -10°, with an application in the conservation of perishable food and some medicines such as insulin.
Currently they use fluid that contribute to global warming. Using CO2 or carbon dioxide as a refrigerant is common in Europe but nor in America, hence the professor proposes a change in the fluids used in Mexico for the acclimatization and refrigeration.
"When I presented this work to people from the Netherlands and Germany, they were surprised because they thought only United States was incurring in the area, then they mentioned that Mexico is in the competitive development," said the full-time professor of the Division of Engineering.
Currently, luxury automotive companies are using this technology to acclimate their units. Other companies opt for a synthetic fluid, explained Pérez García, at the time of pointing out the use of this product has its advantages and disadvantages: in case of CO2 leaks, since it is a natural gas, contributes to the cycle of carbon and doesn't affect the atmosphere, in addition that its cost is equal to the 25% of the most used fluid today.
However, the construction is not so economic, but it proposes something similar to what happened 10 years ago with the solar panels: that the investment was high, but when the new technology was proven the costs diminished and became more competitive.
He complemented his thesis in Spain, in a stay at the Universitat Jaume I and perfected it on Holland, at the Technologic University of Delft. His thesis advisors were Dr. Juan Manuel Belman Flores from UG and Dr. Joaquín Navarro Esbrí, in Spain.
The university professor received the recognition from the President of the Mexican Society of Thermodynamic; Dr. Ascensión Romero Martínez, during the National Congress of Thermodynamic held in the Technological Institute of Durango, led by the engineer Jesús Astorga Pérez.
Finally, he thanked the University of Guanajuato for the support given to make his stay abroad and present his work in the International Conference Gustav Lorentzen.
