  • Patent number: 6318102
    Abstract: A vehicle air conditioning apparatus, provided in a vehicle where plural rows of seats are arrayed in the front-to-rear direction of the vehicle, comprises a cooler duct for guiding cool air from a cooler unit of an air conditioning unit to a portion above and between a first rear seat positioned on a second row of seats from a vehicle front and a second rear seat positioned behind the first rear seat. The cooler duct has a first outlet for ejecting cool air to the first rear seat side and a second outlet for ejecting cool air to the second rear seat side, and the first outlet is arranged in a position away from a seated portion of the first rear seat.

  • Patent number: 5603226
    Abstract: This invention has as its object to provide a method and apparatus for controlling a vehicle air conditioner, which can obtain a combination of an outlet air flow rate V.sub.a and an outlet air temperature T.sub.o, which is desirable for comfort of a passenger, under a condition of air-conditioning control based on a heat balance equation. In order to achieve this object, this invention provides a method of controlling a vehicle air conditioner, including the first step of obtaining, from a heat balance equation, a plurality of combinations of the outlet air flow rates V.sub.a and the outlet air temperatures T.sub.o necessary for maintaining the passenger room temperature to be a predetermined target temperature, the second step of calculating comfort indices each representing the comfort level of a passenger on the basis of state amounts of factors which influence comfort felt by the passenger in the passenger room, and the plurality of combinations of the outlet air flow rates V.sub.

  • Patent number: 5518065
    Abstract: An air conditioning control method of a vehicle includes the step of determining a target temperature of a passenger compartment of the vehicle, calculating a comfort index provided as a function of at least an outlet air temperature and outlet air volume flowing out of a heater-air-conditioner system in which air is treated to be introduce to a passenger compartment, setting a target comfort index, determining an optimized combination of the output air temperature and the output air volume which minimizes a deviation of the comfort index from the target comfort index, compensating the target temperature to reduce the deviation when the deviation is greater than a predetermined value. The optimized comfort level can be accomplished quickly through the control.

  • Patent number: 5433266
    Abstract: The present invention relates to an air-conditioning apparatus provided in an vehicle. The apparatus is adapted to deliver conditioned air into a passenger compartment so as to regulate an interior temperature of a passenger compartment at a desired temperature. The apparatus comprises a temperature regulating device for regulating an outlet air temperature, a blower, and a controller for setting a target outlet air temperature and volume.
