Abstract
Nowadays, with the increase in energy consumption, governments are forced to apply various tariffs to optimally control energy consumption in society. For this reason, electricity consumption meters have been designed and implemented in three modes: low, medium, and peak load. One of the methods that can be used in the summer season to reduce energy consumption is to store cooling load in low-load hours and use it during high-load hours. In this design, an ice chiller is used to prepare ice in a tank. In this thesis, first, a 5-story, two-unit building in the east of Tehran was dynamically simulated with Design Builder software, and accurate heating and cooling loads were obtained. Then, the ice tank was designed in such a way that it can cool all the units from 1:00 p.m. to 11:00 p.m. The amount of savings in the simulation with this year’s electricity tariff was about 965$ in one year, which will result in a return on investment of about 5 years for this building. Also, to reduce energy consumption during the day and based on accurate simulation results, 20 high-efficiency 500-watt panels were used to provide electricity for lighting and equipment, which economic calculations showed that this amount will be returned in less than two years.
