This document is applicable to the calculation, measurement and/or verification of energy consumption of railway vehicle HVAC (Heating, ventilation and air-conditioning) systems. The HVAC system energy consumption is simulated, calculated, measured and validated in accordance with the requirements of thermal comfort defined in ISO 19659-2, considering the same category of passenger railway vehicles as detailed in ISO 19659-2, Clause 4. – Category 1 (e.g. main line, intercity, long distance, high speed); – Category 2 (e.g. suburban, commuter, regional); – Category 3 (e.g. urban, LRV, tram, metro/subway). This document will only cover the passenger area HVAC systems. Driver’s cab HVAC systems are excluded but could be treated in a similar way.
