Definitions

  • the invention concerns a process for operating an air conditioning system in the passenger compartment of a motor vehicle of the generic type described in the pre-characterizing portion of claim 1 .
  • the invention further concerns an air conditioning system for a motor vehicle according to the pre-characterizing portion of claim 6 .
  • DE 197 20 293 C1 describes a device and a process for ventilation of a motor vehicle internal space depending upon corrosive gas. There, in the case that harmful substances or pollutants are detected in the outside air, the air conditioning system is switched from a normal fresh air mode operating condition to a recirculation mode.
  • a climate control system and a process for controlling thereof is known from DE 198 50 914 A1.
  • CO 2 is employed as the cooling agent (refrigerant) and a CO 2 -sensor is located in the flow down stream of the heat exchanger, which sensor can detect possible damage of the heat exchanger and interrupt air supply to the passenger compartment of the motor vehicle in order to protect the health of the occupants.
  • the climate control system switches, upon exceeding a predetermined CO 2 -threshold value, which is measured in the passenger compartment of the motor vehicle, into the fresh air ventilation mode.
  • the air quality in the passenger compartment is thus determined by the CO 2 content of the air, and by the switching into the fresh air ventilation mode upon reaching a predetermined threshold it is ensured that the internal space is always supplied in sufficient manner with oxygen-containing fresh air.
  • the CO 2 content thus serves as indicator for the air quality in the passenger compartment of the motor vehicle.
  • the climate control system can generally be operated in recirculation mode for a substantially longer period of time than is the case with a time controlled system, which operates based on the presumption of an average, though not maximal, occupancy of the internal space.
  • a climate control system for a motor vehicle is disclosed in claim 6 .
  • a CO 2 -sensor is provided in the passenger compartment of a motor vehicle, which triggers or actuates, upon exceeding a CO 2 -threshold value, a switching of the control system from recirculation mode to fresh air mode.
  • FIG. 1 a motor vehicle with an inventive climate control system
  • FIG. 2 an enlarged representation of the climate control system of FIG. 1
  • FIG. 1 a motor vehicle 1 is shown, which includes a passenger compartment 2 , and engine compartment 3 and a trunk 4 .
  • the passenger compartment 2 there is located, in known manner, front seats 5 and back seats 6 , of which basically only a single one is represented.
  • the dashboard 7 In front of the front seat 5 is the dashboard 7 with a steering wheel 8 and an ashtray 9 .
  • a console 10 On the front seat 5 there is provided a console 10 , into which an ashtray 11 reachable from the backseat 6 is incorporated.
  • a climate control system 12 is provided in the dashboard 7 , of which individual components are shown in detail in FIG. 2 .
  • the climate control system 12 includes a blower 13 , with an evaporator 14 downstream in the flow of air, with the direction of flow shown by arrows.
  • An intake 15 leads to the blower 13 , which after evaporator 14 branches into three lines 16 , 17 and 18 . From this, the first line 16 leads to the windshield 19 of the motor vehicle 1 , the second line 17 leads to the vent in the direction of the steering wheel 8 and the third line 18 opens into the foot space 20 , which is part of the passenger compartment 2 .
  • the intake 15 to the blower 13 is supplied with air from the foot space 20 for recirculation and also by a fresh air line 22 . If the blower 13 intakes air essentially from the recirculation line 21 , then it is in the recirculation mode, since the internal space 2 is then essentially supplied by recirculated passenger compartment air. If the intake 15 intakes at least a certain portion via the fresh air line 22 , than this case is referred to as the fresh air mode of the climate control system 12 .
  • a control element 23 is provided embodied in the present case as a flap or valve, which can be adjusted stepless using an adjustment device 24 embodied as a step motor.
  • the climate control system 12 is operated in the recirculation mode, since thereby in particular during supplying of cooler air in the passenger compartment 2 a substantial amount of energy can be saved.
  • the fresh air amount is variable and depends upon the control of the control element 23 .
  • control over the climate control system 12 is exercised by a control device 25 , which as conventional is located in the engine compartment 3 or in the dashboard 7 , however, for space reasons, is shown in the figure outside of the motor vehicle 1 .
  • the control device 25 is further connected with a CO 2 -sensor 26 located in one foot space 20 of the passenger compartment 2 , wherein of course any larger number of CO 2 -sensors 26 can be provided.
  • the CO 2 -sensor 26 measures the CO 2 concentration in the passenger compartment 2 of the motor vehicle 1 and, in the case of exceeding a certain predetermined CO 2 threshold value in the passenger compartment 2 , provides a signal to the control device 25 , so that this is switched from the previously existing recirculation mode to the fresh air mode.
  • the control element 23 must be moved by means of the actuator or adjustment device 24 from the fresh air line 22 in the direction of the recirculation line 21 .
  • the mode of operation of the climate control system 12 is dependent upon the CO 2 content in the passenger compartment 2 of the motor vehicle 1 and it is ensured that the occupants in the case of exceeding a predetermined CO 2 -threshold value are supplied with fresh air.
  • this CO 2 -threshold value is approximately 800 ppm.
  • the CO 2 -sensor 26 or, as the case may be, the control device 25 can be set to other CO 2 -threshold values, when this is considered useful or necessary.
  • the quality or as the case may be composition of the environmental air can also be taken into consideration.
  • the control device 25 is further connected with two sensors 27 and 28 , which are associated with the ashtrays 9 and 11 . As soon as the corresponding ashtrays 9 or as the case may be 11 are opened, this is detected by the sensor 27 or as the case may be 28 and relayed to the control device 25 , which subsequently switches via the adjustment device (actuator) 24 and the control element 23 of the climate control system 12 as described above into the fresh air mode.
  • the control device 25 which subsequently switches via the adjustment device (actuator) 24 and the control element 23 of the climate control system 12 as described above into the fresh air mode.
  • Such a supplemental control of the switching of the climate control system 12 from recirculation mode into fresh air mode in response to the ashtrays 9 and 11 is useful, since during smoking increased amounts of CO, NO x , etc. are produced and thus an earlier switching into the fresh air mode is desirable.
  • additional ashtrays can be provided with appropriate sensors.
  • other sensors can also be provided in the passenger compartment 2 , with which it can be determined whether smoking is taking place in the internal space 2 of the motor vehicle 1 . It can be advantageous to switch completely to the fresh air mode if one of the sensors 27 or 28 is activated.
  • the sensors 27 and 28 can of course also be activated independent of the CO 2 content measured by the CO 2 -sensors 26 , and switch the climate control 12 into the fresh air mode.
  • the CO 2 -sensor 26 is also very effective and other sensors can be dispensed with in the case that the cooling agent for the evaporator 14 is CO 2 . Thereby a possible leakage of the evaporator 14 can be very quickly detected and the climate control system 12 can be switched off and the blower 13 , following switching of the control element 24 to fresh air operation, can possibly also be switched to an elevated or as the case may be maximal blower setting, so that a safety device is provided for the occupants by the CO 2 -sensor 26 , the control device 25 and the control element 23 . In order to accomplish this switching off by the control system 12 , as shown in FIG.
  • the evaporator 14 can be provided on the pressure side with an expansion valve 29 , which separates the evaporator 14 from the circulation, and which blocks it when the CO 2 -sensor 26 detects a CO 2 leakage, or when the CO 2 -sensor 26 or as the case may be a control signal is lost, for example following an accident.
  • a compressor 31 connected via a line 30 with the evaporator 14 , in the supply line 32 of which a vacuum valve 33 is provided. This valve 33 serves to switch off the compressor 31 in cases of possible leakage of the evaporator 14 .
