Measurement and design optimization of air conditioning load inequipment and management room of a subway station in Xiamen

The running state of the air conditioning system in the equipment and management room of a station of Xiamen Metro Line 1 is tested, including the room supply/return air rate, room supply/return air temperature and humidity, room internal surface and equipment surface temperature, and other parameters. The actual room air conditioning load and equipment heat output are calculated. According to the test and calculation results, it is found that the personnel load, design lighting load and equipment load are too large. Therefore, the parameter value of air conditioning load calculation is optimized. Taking the station as an example, the optimized air conditioning load is reduced by 34% compared with the design load, and the energy saving effect is remarkable.
