VEHICLE AIR CONDITIONING SYSTEM Russian patent published in 2003 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to systems aimed at providing control of microclimate in car interiors and van bodies accommodating computing, medicinal, measuring, geological and other similar equipment serviced by operators. Proposed system contains air conditioner communicating through delivery and heat-insulated air ducts with van body interior. Novelty is than L- shaped heat-insulated air duct is rigidly secured on vehicle roof and its longitudinal lower part is formed by roof of van body on which different height guides are rigidly secured to take in air flow. Holes are made in guides to direct air flow into van body interior. Hood is installed over heat-insulated air duct. Suspended ceiling is made in form of sheet following profile of ceiling of van body, being secured on van body ceiling by vertical posts. Delivery heat-insulated air duct consists of two metal housings separated by heat-insulating material. Air processing set of air conditioner is installed in noise isolated compartment of front part of van body, and compressor-condenser set is arranged between van body and vehicle cabin. EFFECT: improved comfort, provision of optimum operating conditions as to noise level, air velocity, cleanness of air and its temperature. 3 cl, 6 dwg
