Özet

In this study, utilization of a solar energy powered absorption cooling system has been investigated instead of conventional cooling systems for milk cooling purpose as an alternative method. In this study, a novel designed milk tank (1000 liter tank capacity and 2BII performance class) with rollbond type heat exchanger around the wall and conventional heat exchanger bottom of the tank for vapor compression cooling system was used. Performance investigation of the tank has been realized while the first and last milking experiments according to International and National Standards for the milk storage tank. Experimental studies have been realized for the hybrid combination of the conventional (vapor compression) cooling and the LiCl-H2O absorption cooling systems with an internal energy storage ability. According to experiments, the conventional and absorption cooling method were cooled down the milk at the first milking period in the reasonable time interval. On the other hand, while the conventional method was being completed in the reasonable time interval, hybrid method was not able to complete in accepted time limit. Utilization of the hybrid combination of the LiCl-H2O absorption and conventional cooling system showed 18.01 Wh/L specific energy consumption, but conventional cooling system showed 21.06 Wh/L specific energy consumption at the same cooling amount. In Turkey, utilization of solar and geothermal energy powered absorption cooling systems to increase energy savings in different cooling application can be significant method since Turkey has advantages about renewable energy sources such as solar and geothermal energy.
