加尔各答地铁车辆客室空调系统总通风量及制冷量计算

Calculation of total ventilation rate and cooling capacity for air conditioning system of passenger room in Calcutta metro vehicle

文章依据加尔各答地铁车辆车体结构设计参数,参考空调系统设计及计算的相关标准,对加尔各答地铁车辆客室空调系统的总通风量及制冷量进行计算,得出总通风量为11 000 m3/h,制冷量为90 kW。通过与深圳地铁1号线车辆相关设计参数的对比,认为该计算结果是可靠的,进而为客室空调机组的选型提供参考依据。

In this paper, the total ventilation rate and cooling capacity of air conditioning system of passenger room in Calcutta metro vehicle are calculated, according to the structural parameters of Calcutta metro vehicle body and the relative standards of air conditioning system design and calculation. The calculation results are that the total ventilation rate is 11 000 m3/h and cooling capacity is 90 kW. The calculation results are proved to be reliable and can provide a reference for the type selection of the air conditioning unit, through comparing the relative design parameters with Shenzhen Metro Line 1 vehicle.
