VEHICLE CLIMATIC PLANT Russian patent published in 2003 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to systems providing control of microclimate in vehicles. Proposed plant contains compressed air source, heat exchanger, swirl-type energy divider with inlet connected to outlet of heat exchanger, system of pipelines and three valves. Novelty is that proposed plant is furnished with heating device, air conditioner mixing chamber, noise damper, cooling chamber, cold-hold plate, air cleaning unit and two ejectors. Hot flow outlet of swirl-type energy divider is connected through first valve to heating device with discharge of waste air into atmosphere. Cold flow outer of swirl-type energy divider is connected through second valve with ejector of air conditioner installed in mixing chamber and with vehicle interior through noise damper. Cold flow outer of swirl-type energy divider is connected through third valve with cold-hold plate of cooling chamber, outlet of cold-hold plate being connected to inlet of heat exchanger. Air cleaning unit is connected between compressed air source and heat exchanger, and main ejector is connected with compressed air source and outlet of heat exchanger and it communicates with vehicle cab. EFFECT: improved riding comfort, enlarged operating capabilities. 1 dwg
