Air-conditioning system for vehicle with switch-off function for pushing mode, working in relation to switched on mode

摘要

The vehicle is equipped with a system switching the driving mode of the engine from pushing to pulling and vice versa if required. The air-conditioning system is designed in order to be operated with fresh air when the engine works in the pushing mode and with reused air when the engine is switched to the pulling mode. A control unit changes the system automatically using the information about the duration of travelling in a specific mode or the moisture level inside the passenger cabin. The change between the conditions is performed gradually.
