Optimization of air conditioning systems utilizing low temperature thermal storage; Optimizacion de sistemas de acondicionamiento de aire utilizando sistemas de almacenamiento termico de baja temperatura

Abstract

In the last few years the different projects on the saving and efficient use of energy in the tertiary sector have been demonstrating the existing great potential in the air conditioning systems and equipment, whose intensive use is due to the predominance of hot and dry and hot and humid climate prevailing in a large part of the Mexican territory. Without any doubts one of the most serious problems facing the complex management and optimization of these systems is related to the variability of the thermal load and the regulation possibilities of the thermal machines, so as to attain, along the day an appropriate use and optimization of the total installed load, with the best possible economic benefits. Among the strategies that allow the optimization of the installed capacity and the variability of the thermal load is the low temperature thermal storage, for instance, the storage of ice, which is produced and stored to be used when the cooling machines are in standby in order to use this stored energy during the peak hours and during the normal operation of the equipment, but diminishing in a significant amount the electrical demand of the system to satisfy the thermal load with  More>>

This paper presents some case histories and the type of thermal storage commonly used; a methodology is discussed that allows to determine technically as well as economically the size of a thermal storage room. Some problems in the control and operation of these thermal systems are also presented. [Espanol] En los ultimos anos los diversos proyectos sobre ahorro y uso eficiente de la energia en el sector terciario han venido mostrando el gran potencial existente en los sistemas y equipos de aire acondicionado, cuyo uso intensivo se debe al predominio de los climas calidos seco y calido humedo en buena parte del territorio nacional. Sin lugar a dudas uno de los problemas mas serios que enfrenta la compleja gestion y optimizacion de estos sistemas esta relacionado con la variabilidad de la carga termica y las posibilidades de regulacion de la o las maquinas termicas, de tal manera de lograr, a lo largo del dia, un adecuado uso y optimizacion de la carga total instalada, con los mejores beneficios economicos posibles. Entre las estrategias que permiten optimizar la capacidad de la instalacion y la variacion de la carga termica esta el almacenamiento termico de baja temperatura, por ejemplo, el almacenamiento de hielo, el cual se produce y se almacena durante las horas en que normalmente las maquinas de refrigeracion estan paradas, y con el fin de usar esta energia almacenada durante el horario pico y durante las horas de operacion normal del equipo, pero disminuyendo en forma importante la demanda electrica de la instalacion al satisfacer la carga termica con una combinacion almacen termico-maquina de refrigeracion. En este trabajo se presentan algunos antecedentes y tipos de almacenes termicos utilizados comunmente, se discute una metodologia que permite dimensionar un almacen termico, tanto tecnica como economicamente, y se plantean algunos de los problemas en el control y operacion de estos sistemas termicos.}
