FIELD: transport. ^ SUBSTANCE: invention relates to passenger car ventilation and air conditioning systems. Passenger car ventilation system consists of external air intake grid, air filter, supply fan, water or electric fan heater and influent air pipe with outlets arranged along the car length. Additionally, ventilation system comprises refrigerating machine, exhaust fan and air duct, external air exhaust grid, condensate collector and condensate discharge pipeline. Refrigerating machine represents one-piece plant consisting of heat-and-noise isolated two-compartment housing. First compartment accommodates air cooler and supply fan. Said air cooler communicates with air filter via air duct. Second compartment accommodates compressor, four-way valve and condenser communicated via pipelines with control and protection elements, and exhaust fan. Intake chamber of exhaust fan communicates with exhaust pipeline, while pressure chamber communicates with exhaust air external grid. Condensate collector is mounted at car body bottom and communicates with condensate discharge pipeline. ^ EFFECT: reduced costs of passenger car ventilation system operation. ^ 3 cl, 1 dwg |
