VEHICULAR AIR CONDITIONER, AND METHOD OF TEMPERATURE CONTROL BY THE VEHICULAR AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To improve riding comfort in a vehicle compartment by controlling the volume and temperature of air blown into the vehicle compartment independently so as to provide warm air and cool air controlled to a desired temperature and prevent a drop in volume and a rise in temperature at maximum cooling.SOLUTION: First and second blower units 206 and 212 supply air to a casing 202, in which cool air cooled by an evaporator 208 and warm air heated by a heater core 210 are mixed together and blown out to front and rear seat sides of the vehicle. At this time, temperature control dampers 252a and 252b for controlling the temperature of air blown out into the vehicle compartment direct the flow of warm air subjected to heat exchange in the heater core 210 in the direction where the evaporator 208 is installed to make the flow of warm air opposite to the flow of cool air subjected to heat exchange in the evaporator 208, so that the cool air and the warm air are mixed appropriately.
