AIR CONDITIONING SYSTEM FOR AUTOMOTIVE VEHICLES

摘要

PURPOSE: An air conditioning for a vehicle is provided to prevent the unnecessary air-flow resistance generation by preventing cold air of an evaporator passing through an electronic heater. CONSTITUTION: An air conditioning for a vehicle comprises an air conditioning case(10), an evaporator(12a), an electric heater(12b), a defrost bent(20), a face bent, a floor bent(24), a bypass path(30), a rotary door(40), and a controller(60). The bypass path bypasses to a branched point of the defrost bent and face bent before passing through the electronic heater. The rotary door is installed in the branched point of the defrost bent and face bent to be rotated. The controller controls the rotary door so that some of cold air have passed through the evaporator by opening the bypass pass is directly supplied to the defrost bent and face bent.
