Air conditioning energy accounts for more than 50% of the total energy used in buildings. Recently, in general office buildings the cooling load of winter is increasing as it has a server room by establishing its own computer system for the purpose of managing computer and data and strengthening security. As the cooling load of winter increases, a study combining a TES (thermal energy storage) system that reduces operation costs by transferring power demand to late-night hours and a free-cooling system that reduces cooling energy consumption by using low-temperature outdoor air under conditions below a specific temperature is in progress. Therefore, this study intends to deepen the study by focusing on previous studies that implement a complementary model of each system for a building that is subjected to a 24-hour cooling load even in winter. By using DesignBuilder, a dynamic simulation program, cold water produced through WSE is used for 4 months during the winter (December to March) when the outside temperature is low to remove the load occurring at night. At the same time, in this study intend to implement a TES-linked free-cooling system that stores cold water in the TES and discharges heat during the next daytime, and the system will be referred to as a “Combination model”. Buildings and equipment were modeled with reference to ASHRAE standards and guidelines. For the target building, energy consumption and cost savings of cooling operation were reviewed using standard meteorological data of Seoul, and heating operation was excluded from the simulation model. As a result of analyzing the simulation, it was confirmed that the combined model reduced energy consumption by 27% and operating cost by 51% compared to the conventional method. |
