Military shelters contain various electronic devices that generate significant heat during operation due to their high power output. This heat buildup can degrade the performance of the equipment and shorten its operational lifespan. In high-temperature environments, overheating can lead to serious malfunctions in communication systems or information management platforms, jeopardizing the efficiency and reliability of military operations. Conversely, in low-temperature or high-humidity conditions, condensation may form inside the shelter, increasing the risk of physical damage to electronic components. Such damage can significantly compromise the reliability and durability of the equipment, raising the likelihood of system failure. This study proposes using various environmental control systems, including heating, ventilation, and air conditioning (HVAC) units and air ducts, to mitigate the adverse effects of temperature and humidity fluctuations within military shelters. To achieve this, thermal analysis models were utilized to evaluate and verify the performance of these systems. The analysis specifically examined the heat output of individual devices to determine if the proposed control systems could effectively maintain optimal operating temperatures within the shelter. The results of this study aim to provide a valuable foundation for designing environmental control systems that ensure thermal stability in military shelters.

In modern society, industries are being upgraded in various fields. In particular, the defense industry has developed numerous technologies, such as the localization of core military technologies. The defense industry is actively studying technologies in areas such as in helicopters and tanks. In the case of radars, research on the radar itself is very active as is the research on the components that make up the radar. In this study, the temperature distribution of the two types of evacuation centers that make up the radar were analyzed using Computer Fluid Dynamics (CFD) to identify the temperature distribution based on the internal structure of the shelter. The two types of shelters have different heating values in different arrangements in the shelter provided they have the same size of heat source. Simulation results showed that the average temperature at the KA LNA shelter was different. In this study, we analyzed the effects of internal structure on the temperature and confirmed that the internal temperature may be decreased by changing the structure without using an external cooling element.
