Leak detection method, especially high-speed train carriages, in which the vehicle interior is over pressurized and heated or cooled using the vehicle climate control system and leaks are then checked for using thermography

摘要

Method for locating leaks between the interior of a vehicle or carriage and its exterior, whereby the air in the interior volume is raised to a higher pressure and a higher or lower temperature than air in the exterior atmosphere. Optimally the over pressure and temperature difference are generated using the vehicle's own air conditioning system. Leaks are detected using thermal imaging cameras.
