Economic researching of cooling storage in variable electrical price

Chiller system?s capacities are calculated to maximum cooling load that optimized with maximum temperature and operation hour in buildings areas. They will be worked out of peak load times and increase first investments so it causes down the output. In solution to these problems, we can use cool storage systems. In this context we can run the Chiller in other times and than use this cooling energy in operations times therefore chiller capacity is less than before.On the other hand electrical price is changed with last legal arrangements that three times as different price for blocking peak load in electrical trafo and cables. So we can run up the Chiller in economical times for cooling the storage. In this theses, there is a search in concordance with above text doing numerical and economical analysis.Keywords: Cooling systems, Cooling storage, Investment/Running cost.
