Análisis de un sistema energético alternativo para el calentamiento de agua sanitaria en la compañía de economía mixta hotelera y turística Ambato

Abstract

The experimental work is focused on mitigating the emission of greenhouse gases from the burning of Liquefied Petroleum Gas, while operating a Solar Thermal System (SST) that is nearing its useful life, since its installation dates back to 2013, so it is appropriate to consider new alternatives to reduce the environmental impact and supply the energy demand of 59,533.43 (kWh/year). For sanitary water heating, the operational percentage was calculated, the main system is (SST) same that covers 57 percent and the auxiliary system comprises the use of 4 heaters that cover 43 percent, in this sense, the historical data survey was performed during the period (2018-2023), because the hotel demand was directly affected by the pandemic of COVID-19, the data obtained were essential to raise the real situation of the hotel and as a result the study of the different alternatives of thermal generation for Sanitary Hot Water (SHW) was carried out. In order to mitigate the consumption of LPG, different alternatives were established to cover the energy demand: Solar Thermal Collectors, Condensing Gas Boilers and Heat Pump. Based on different configurations, it was determined that the most viable option is the Mixed System between Heat Pumps and Solar Thermal Collectors, because it meets the previously established energy demand and at the same time its operating cost is lower compared to the other proposals.
