Definitions

  • the invention relates to an air conditioning system for a passenger compartment of a vehicle having a rear, according to the preamble of claim 1.
  • an air distribution chamber is arranged behind each backrest of a front or front seat, which together delimit the rear of the passenger compartment to the front, and is connected to an air duct in each case.
  • the two air ducts are laid on the floor of the passenger compartment. The air flowing in each air duct is brought to the desired temperature in a heat exchanger.
  • the two heat exchangers are each arranged on a door pillar in the front compartment of the passenger compartment and have additional air outlet slots for ventilation of the front compartment.

  • the air flow is cooled in the evaporator arranged in a refrigerant circuit, and the air flow is heated again in the heat exchanger arranged in the coolant circuit of the internal combustion engine of the vehicle.
  • the heat exchanger is divided into four sectors, of which the two upper sectors for heating the left and right halves of the front space and the two un- Other sectors are provided for heating the right and left half of the fund. From the two lower sectors there are two pairs of air ducts, one pair leading to the left and one pair to the right half of the fund. Each air duct is closed with an air vent, one of which is arranged in the left and right half of the fund in the footwell and the other air vent in the center plane of the fund for direct air flow to the rear passengers.
  • the invention is based, an air conditioning system of the type mentioned with the same climate comfort in the task
  • the air conditioning system according to the invention has the advantage that only one air duct is required for the air flow to each half of the fund, the distribution of the conditioned air supplied to the rear being maintained at the footwell and middle level.
  • an air distribution element is provided at the branch point of the duct branch in the air duct, which, depending on the "heating" and “cooling” mode of the air conditioning system, distributes the air on the two air vents.
  • the amount of air flowing into the footwell is preferably throttled or completely shut off and in the "heating" operating mode the larger amount of air is blown in via the footwell.
  • the invention is described below with reference to an embodiment shown in the drawing.
  • the drawing shows a schematic representation of an air conditioning system for a passenger compartment of a vehicle.
  • the air conditioning system which is shown only schematically in the drawing, is used for air conditioning a passenger compartment 10 of a vehicle, which is equipped with two front or front seats and a rear or rear seat bench. Instead of the rear bench seat, there can also be several single or double seats. From the front seats only the backrests 11 and 12 and from the rear bench only the backrest 13 are indicated by dashed lines.
  • the arrangement of the front seats divides the passenger compartment 10 into a front space 14 and a rear 15, which can be individually air-conditioned by means of the air conditioning system.
  • An individual setting of the climate in the left and right half of the passenger compartment 10 is provided both in the front space 14 and in the rear 15.
  • the air conditioning system has, in a known manner, an air conditioning box 16, from which air ducts 17 for ventilation of the front space 14 and air ducts 18 for ventilation of the fund 15 depart.
  • One of the two air ducts 18 leads to the left or right half of the fund 15.
  • the climate box 16 as is known and not shown here, there is an evaporator arranged in a refrigerant circuit and a heat exchanger arranged in the cooling water circuit of the vehicle's internal combustion engine, as well as an air distributor arranged downstream of the heat exchanger, from which the air cooled in the evaporator and heated in the heat exchanger is directed to the air Air channels 17, 18 is distributed.
  • the air flow flowing through the evaporator and heat exchanger and flowing into the air distributor is generated by a fan, which a entrance of the air conditioning box 16 is arranged and optionally draws in fresh air from the vehicle surroundings or recirculated air from the passenger compartment and blows it into the air conditioning box 16.
  • a fan which a entrance of the air conditioning box 16 is arranged and optionally draws in fresh air from the vehicle surroundings or recirculated air from the passenger compartment and blows it into the air conditioning box 16.
  • two air outlets 20, 21 are provided in each half of the fund 15, the air outflow 20 being placed in the footwell and the air outflow 21 in the central plane for direct flow against the rear passengers sitting on the rear bench.
  • the air vents 21 are shown next to the air vents 20 for the sake of simplicity. However, they are more real in a plane running above the level of the air vents 20.
  • the air vents 20 placed in the footwell close off the end of the air channels 18 opening in the rear 15, while the air vents 21 arranged in the central plane are each arranged at the mouth end of a channel branch 19 extending from the air channel 18.
  • the branching of the duct branches 15 is made as close as possible to the end of the air ducts 18 on the fund side.
  • At each branch point of the duct branch 19 there is an air distribution element 22 for dividing the air volume flowing in the air duct 18 between the two air outlets 20, 21.
  • Each air distribution element 22 is designed so that the distribution of the air volume flow between the air vent 20 and the air vent 21 is dependent on the operating mode "cooling" and "heating" of the air conditioning system.
  • the dependency of the distribution of the volume flow on the operating mode is such that in the "cooling" operating mode the partial air flow to the air vent 20 in the footwell is throttled to a very great extent or almost completely blocked.
  • the air volume partial flow reaching the air vent 21 in the middle plane is increasingly throttled as the desired temperature of the air-conditioning air increases.
  • the air distribution element 22 has an air flap 23 and an air flap 23 driving swivel drive 24, which brings the air flap 23 into a desired swivel position between two end positions.
  • the duct branch 19 In the end position of the air flap 23 shown in solid lines in the drawing, the duct branch 19 is completely closed and the entire air volume flow is supplied to the air outflow 20.
  • the duct branch 19 In the end position of the air flap 23 shown in dashed lines in the drawing, the duct branch 19 is completely released and the air supply to the air vent 20 in the footwell is completely shut off.
  • the swivel drive 24 is designed as a servomotor which is controlled by a comparator 25 used as a setpoint / actual value comparator.
  • the comparator 25 is connected on the input side to a temperature sensor 26 and a temperature pre-selection element 27 and compares the temperature setpoint set on the temperature pre-selection element 27 with the actual temperature value supplied by the temperature sensor 26. If the actual temperature exceeds the temperature setpoint, the air conditioning system will operate in its "cooling" operating mode, and the swivel drive 24 will be provided with an actuating signal such that it strongly throttles the partial flow of air to the air vent 20 in the footwell, that is to say Air flap 23 transferred in the direction of the end position indicated in dashed lines in the drawing. As is not shown further here, the size of the setpoint / actual value difference can be used to determine the size of the throttling of the partial air flow.
  • the temperature setpoint value set by means of the temperature preselection element 27 is greater than the actual temperature value supplied by the temperature sensor 26, an opposing control signal is applied to the swivel drive 24 via the comparator 25.
  • the swivel drive 24 now pivots the air flap 23 in the direction of the end position shown in solid lines in the drawing, so that the partial air flow that reaches the air vent 21 placed in the central plane is throttled.
  • the size of the setpoint / actual value difference can also be used here, the size of the Throttling of the partial air flow to the air vent 21 to be determined.
  • control signal for the rotary actuator can be generated or modified as a function of the ventilation temperature, so that the size of the throttling of the partial air volume flows is determined by the ventilation temperature.
  • the ventilation temperature can be detected directly in the air flow flowing in the air duct 18 or at another point in the air conditioning system at which there is an equivalent temperature profile as in the air duct 18.
  • a second air duct 18 with all the associated components is of course omitted, so that they are only present once in the structure and context described.
  • a plurality of air vents 20 in the footwell and a plurality of air vents 21 in the central plane in each half of the rear which are connected together to the same air duct 18 or duct branch 19.

Abstract

L'invention concerne une installation de climatisation destinée à l'habitacle (10) d'un véhicule automobile, cet habitacle ayant une zone arrière. L'installation de climatisation comprend au moins un canal d'air (18) qui conduit à l'arrière (15) et est alimenté en air d'une température présélectionnée, et au moins un dispositif d'écoulement d'air (20, 21) qui est relié au canal d'air et placé à l'arrière de l'habitacle. L'invention vise à simplifier la construction de la climatisation de l'arrière de l'habitacle et à en réduire les coûts de production tout en conservant le confort climatique à l'arrière (15). A cet effet, on dote le canal d'air (18) d'une branche qui est fermée par un deuxième dispositif d'écoulement d'air placé à l'arrière de l'habitacle. De plus, un organe de distribution d'air (22) placé à l'emplacement de dérivation, répartit le flux de volume d'air s'écoulant dans le canal d'air entre les deux dispositifs d'écoulement d'air (20, 21) et donc permet que la répartition du flux de volume d'air dépende du mode de fonctionnement 'refroidissement' et 'chauffage' de l'installation de climatisation.
