Research on Improving Technology of Man-machine Comfort of Equipment Shelter

The function and performance requirements of modern radars are getting higher and higher, the amount of equipment in the shelter has increased sharply and heat dissipation and noise increasingly affect the man-machine comfort of the shelter. Thermal control design of the traditional equipment shelter is usually carried out in a human-machine mixed environment. In order to ensure the normal heat dissipation of electronic equipment, the temperature in the personnel area is lower than the comfortable temperature of human body for a long time. At the same time, in the case of a large amount of equipment in the shelter, the noise reduction design is also difficult to meet the requirements of the national military standard. In this paper through the top-level overall consideration, the design of thermal control and noise reduction is optimized. Two independent air supply systems are installed in the shelter to realize normal heat dissipation of the equipment and suitable temperature in the personnel area. Innovation design of the air duct is carried out that the two systems can back up each other under emergency conditions to ensure the normal operation of the equipment. At the same time, by taking effective measures such as controlling the noise source and arranging silencing channels reasonably, it is ensured that under full load conditions the maximum noise of the whole shelter is lower than the national military standard requirement of 65 dB(A). Thus, the man-machine comfort of the equipment shelter is improved and the design ideas are provided for the future shelter design.
