Aplicación de la simulación energética de edificios en la validación de estrategias operacionales de sistemas HVAC en un hotel tropical. Ingeniería Mecánica [online]. 2017, vol.20, n.1, pp.31-38.

This paper validates a trading strategy of a water-cooled chiller centralized system on a tropical hotel considered a transit hotel during last year 2013 was implemented empirically. For the same thermal loads climate with a building simulation tool called TRNSYS software for critical conditions, occupancy, weather and constructive characteristics of the system was calculated. Thermal load profiles for different levels of occupancy, comparing the installed thermal capacity were evaluated. Also it takes into account the particularities of occupancy in the hotel. This research proposed measures that complement the hotel’s energy management. Finally the strategy implemented allowed the hotel, savings403 123,76 kWh/year, and issuing leaving 371,27 t of CO2/year into the atmosphere. It meant about average consumption of the whole hotel for three months. It had an economic impact of 53212,33 USD/year.
