| Popis: | The possibility of using alternative cold supply in the life support systems of buildings for the climatic conditions of the Central Black Earth region is considered. The results of calculations and selection of an absorption chiller with an array of solar collectors for an office building planned for construction in Voronezh are presented. The analysis of the efficiency of the heat collectors by the average efficiency showed that for the cold supply of the building taking into account the actual actinometric indicators of the region the use of flat devices was the most appropriate. Vacuum collectors for the solved task under the indicated climatic conditions, despite the generation of a high-potential thermal regime, upon reaching the maximum temperature of the coolant, are characterized by a decrease in efficiency as a result of significant losses to the environment. With justified priority use of flat devices capturing solar radiation, for a deeper extraction of alternative energy, an innovative design of devices of this class is proposed making it possible to increase their efficiency. The use of such devices will reduce their number in the array. |
