Diseño de una propuesta que permita disminuir el consumo energético del sistema de climatización en el Edificio las Palmas de la Pontificia Universidad Javeriana Cali

Abstract

The objective of this project is to propose a design of a system that allows to reduce the energy consumption of the HVAC systems of the Las Palmas building at Javeriana University, by means of the reduction of the thermal loads that affect them. To achieve this end, a detailed characterization of the building of construction, materials and geometrical aspects was carried out, as well as information on the operation of this, its components, location and climatic conditions of the environment. Subsequently, the calculation of internal and external thermal loads based on the book Técnicas de climatización of A.L. Miranda, which allowed to identify the variables necessary to carry out said calculation. Once the calculation was made it was possible to determine the highest thermal load that affects the structure, which are computers, ceiling and lighting. Consequence of the above, a systematic search was carried out through secondary sources and databases to determine existing technologies in the market that would reduce the most critical problems evidenced in the calculation of thermal loads. These technologies were evaluated according to criteria established by the authors, in order to choose the technologies with the greatest impact, and thus fulfill the general objective of the project, which focuses on the design of a system. Finally, in order to establish the technical, economic and cost-benefit feasibility of the system, thermal loads were re-evaluated with respect to the new specifications of the technologies, the return period and the savings in CO2 tons were calculated. As a result, savings of 10.9% were obtained in tons of refrigeration, which directly affect the electric consumption costs of the air conditioning system and in turn the CO2 tons emitted by it into the environment.
