RUNNING SYSTEM • SUSPENSION • STEERING • BRAKING C. COMFORT SYSTEM • HVAC/AC/HEATER SYSTEM • SEATING/UPHOLSTRY/FACIA/INSTRUMENTS • AUDIO/VIDEO/GPS HEATING, VENTILATION & COOLING HVAC SYSTEM ALLOWS THE PASSENGERS TO CONTROL THE CLIMATIC CONDITIONS INSIDE THE VEHICLE TO THEIR COMFORT & CONVIENIENCE. THE VARIOUS FUNCTIONS OF THE HVAC SYSTEM ARE : COOLING - Brings down the temperature of air inside the vehicle when the outside temperatures are very high HEATING - Brings up the temperature of inside the vehicle when the outside temperatures are very low. VENTILATION - Allows to purge the stale air inside the vehicle and bring in fresh air from outside. HEATING, VENTILATION & COOLING (HVAC SYSTEM - SCORPIO) CONDENSOR HEATER VALVE HEATER EVAPORATOR AC COMPRESSOR BLOWER FAN HOT AIR ATM AIR ENGINE COOL AIR CONDENSOR FAN W A R M A I R RECEIVER-DRIER RD BOTTLE EXPANSION VALVE R-134a REFRIGERANT - CFC FREE HEATING, VENTILATION & COOLING (HVAC SYSTEM - SCORPIO) THE HVAC SYSTEM FITTED ON SCORPIO IS OF AIR MIXING TYPE, WHERE THE DESIRED TEMPERATURE IS OBTINED BY MIXING THE HOT AIR FROM HEATER & COLD AIR FROM THE EVAPORATOR. AIR MIXING IS CONTROLLED BY ADJUSTING THE VARIOUS FLAPS & THE HEATER VALVE INSIDE THE HVAC UNIT.
