The modern data center operates with little human activity, but globally, it consumes nearly 2% of the world's electricity production. With the increase of digital transformation, data center energy consumption will soon reach 8%. In particular, cooling devices account for almost one-third of the electricity consumption of data centers, therefore, effective cooling of data centers has become a challenging problem and an opportunity to reduce IT energy costs and the environmental effects of greenhouse gas emissions. Is. The efficiency of computer room air conditioning (CRAC) systems can be increased by using advanced control techniques, free cooling technologies and the use of renewable energy.
The global development and demand for technology and information services has increased, this has increased their electricity consumption to a significant extent, with the increase in the demand for remote data services, both the workload of the data center and its energy consumption are increasing rapidly. . One of the necessary components of a data center is the cooling system, which places the ambient temperature of the data centers in the standard and optimal range for the operation of the equipment. Among the energy consumption components of a data center, the cooling system can account for 40% of the total energy consumption. Therefore, optimizing the energy efficiency of cooling systems is very important. In this field, energy consumption in the cooling sector of data centers has been significant. In this regard, energy consumption in data centers accounts for about two percent of the world's total energy consumption, which due to the high cost of energy supply and the change in the amount of different time demands, focus on increasing efficiency and useful and effective use of energy and Reducing its wastage increases the efficiency of any energy system. Due to the fact that in most energy projects, the distribution network is designed in static conditions, the necessity of using engineering methods in designing an optimal distribution network in dynamic mode in the field of operation seems necessary and unavoidable.
These goals are studied in two scenarios, considering that in data centers, cooling is needed continuously in all four seasons and every day of the year, and considering that the length of the day and the availability of solar energy provide a significant part of the energy. It is modeled through renewable energy and finally the best model to optimize energy consumption is investigated and concluded.
