Resumen
En este trabajo se realiza un estudio sobre el comportamiento del consumo de energía eléctrica en el sector turístico cubano, en los que se utiliza el kWh/HDO como indicador de la eficiencia. Se denota que los sistemas que consumen más energía eléctrica son: la climatización (42 %), mientras que los motores, elevadores, refrigeración y servicios de lavandería cada uno consume entre un 5 a 7 % de energía. Las variables que más influyen en el consumo son el clima, la categoría del hotel y el tipo de turismo. Se exponen los aspectos técnicos generales que caracterizan a los sistemas de clima y se enfatiza en la Tecnología Inverter, como una de las que se encuentra actualmente en el mercado brindando una disminución del consumo de un 30 a un 40 %. Se caracteriza al Hotel Iberostar Grand Hotel Trinidad en cuanto a su infraestructura, los puntos y puestos claves del consumo energético y el sistema de climatización. Se manifiesta que en el año 2017, con una menor ocupación aumenta el consumo per cápita, aumenta a 41,41 kWh/huesp, esto representa un 8 % respecto al año anterior. Se considera que este incremento se produce por el aumento de la temperatura media anual en Cuba, la afectación del huracán Irma y con la pérdida de eficiencia de los sistemas de climatización. Se propone un sistema VRF marca Carrier modelo Xpower 38 VT-168 HTEE de 168 kW que usa compresor Twin Rotary para surtir la sección de las 40 habitaciones y un chiller YORK modelo YMAA-260 de 255 kW con tecnología Digital Inverter para el resto de las instalaciones. Inversión que permite una disminución del consumo de energía eléctrica del 16,08 % con un plazo de recuperación de 2,3 años.
In this work a study is made on the behavior of electric energy consumption in the Cuban tourist sector, in which the kWh / HDO is used as an indicator of efficiency. It is noted that the systems that consume more electricity are: air conditioning (42%), while engines, elevators, refrigeration and laundry services each consume between 5 to 7% of energy. The variables that most influence consumption are the climate, the category of the hotel and the type of tourism. The general technical aspects that characterize the climate systems are exposed and emphasis is placed on the Inverter Technology, as one of those currently on the market offering a 30 to 40% reduction in consumption. The Hotel Iberostar Grand Hotel Trinidad is characterized in terms of its infrastructure, the key points and positions of energy consumption and the air conditioning system. It is stated that in 2017, with a lower occupancy, per capita consumption increases, increasing to 41.41 kWh / guest, this represents 8% compared to the previous year. It is considered that this increase is due to the increase of the average annual temperature in Cuba, the impact of Hurricane Irma and the loss of efficiency of the air conditioning systems. A Carrier brand VRF system model Xpower 38 VT-168 HTEE of 168 kW that uses Twin Rotary compressor to supply the section of the 40 rooms and a YORK chiller model YMAA-260 of 255 kW with Digital Inverter technology for the rest of the facilities. Investment that allows a decrease in electricity consumption of 16.08% with a recovery period of 2.3 years.
