Item Análisis del suministro de energía para el calentamiento de agua sanitaria del hospital general Ambato (IESS)(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2023-09) Medina López, Patricio Camilo; López Velástegui, Jorge EnriqueIn the first phase of this study, the equipment that is part of the process for the heating of sanitary water in the machine room of the Hospital General Ambato IESS was identified. These components were classified according to their function, whether for the generation and distribution of steam and the exchanger, which is responsible for taking advantage of this fluid in order to add heat to the water that is then distributed to all the blocks of the institution. For the heating of the hospital's sanitary water, 35.526,152 gallons of Diesel No. 2 are required per year for steam generation. Calculations were made of the system losses during the most current period (April 2022 - July 2023) in order to identify any anomalies affecting the operation of the system, by analyzing numerical and quantifiable data. This resulted in an exchanger effectiveness of 41.46 percent. Thermal generation alternatives for sanitary hot water were proposed with the purpose of reducing the consumption of fossil fuels, establishing four possible systems to cover the energy demand, which are: solar thermal collectors and heat pumps; solar thermal collectors and steam; heat pumps and finally the recovery of sensible heat from the dry gases of the boiler chimney, determining that the most viable option are heat pumps because they cover the calorific consumption required per year, additionally its return on investment is shorter compared to the other processes, because approximately in a year and a half the financing will be recovered.Item Determinación de la eficiencia energética del sistema térmico de la casa de máquinas del Hospital General Ambato (IESS) usando la metodología propuesta por ISO 50001(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2022-09) Salazar Aguilar, Jairo David; López Velástegui, Jorge EnriqueFor elaboration of this investigation, at first stage, components in machine room of the entity were identified. These elements are classified according to their sector: in generation, distribution and heat utilization equipment. Based on this, technical information about equipment installed in the place was collected. System losses were estimated according to the most recent period (December 2021 - March 2022), allowing to know anomalies that interfere in the operation of the environment in relation to numerical and quantifiable data. Similarly, financial costs were established about losses, reaching a value close to ten thousand dollars. The efficiency of the steam generator was evaluated at 84.67 percent (useful heat), distribution at 83.75 percent (harnessed heat) and heat exchanger at 42.43 percent. Improvement proposals were suggested that involve equipment cleaning based on maintenance periods, replacement of insulating materials and application of coating on specific surfaces, with the aim of raising the performance of the environment. Thus, the efficiency of the steam system would increase to 84.79 percent (harnessed heat) based on the recalculation with the suggested improvements. In addition, an annual saving of three thousand dollars was determined with a discount rate of 12 percent, with which the associated investment would be recovered in two years.
