METHOD OF AND DEVICE FOR REGULATION AIR TEMPERATURE IN RAILWAY CAR Russian patent published in 1997 - IPC

FIELD: railway transport; ventilation and air conditioning devices. SUBSTANCE: air delivered into car is divided into two streams passing through different sections of heat exchanger with different heat and cold capacity and different temperatures at section outputs and is delivered along different channels into car compartment where streams are mixed and amount of air delivered into car is adjusted to provide maintenance of required air temperature in compartment. Air temperature regulator has filtering and ventilation plant with main and at least one additional air conduits connected to different sections of heat exchanger with different heat and cold capacity. Ventilation outputs of each air conduit in each compartment have controlled louver sets furnished with remote control drive and control unit operating from air temperature setter and air temperature sensor in compartment. EFFECT: enlarged operating capabilities. 3 cl, 4 dwg
