  • the invention relates to a method and a control unit for stationary air conditioning of a motor vehicle interior with a stationary internal combustion engine.
  • the vehicle air conditioning system can be put into operation, for which purpose an electrically operable compressor is provided.
  • the operation of the vehicle air conditioning is hereby 'started by at a lower temperature level than would be the case without solar ventilation. In this way, it is possible to bring the motor vehicle before commissioning, that is, before boarding a person, even on hot days to a tolerable temperature. '' .
  • the invention has for its object to make the stationary air conditioning of a motor vehicle interior as efficient as possible.
  • the invention relates to a method for stationary air conditioning of a motor vehicle interior, which has the following steps when the internal combustion engine is at rest:
  • the blower of the " motor vehicle air conditioning would be put into operation.
  • the power consumption of such a fan is generally greater than the electrical power that can be supplied by a typical solar system in the motor vehicle. Consequently, the battery is discharged by the operation of the blower of the motor vehicle air conditioner, but to a lesser extent than also working compressor.
  • the average electrical power consumption is less than the average electrical power consumption of the blower of the motor vehicle air conditioning.
  • the power consumption of the additional fan which is mounted, for example, in the vehicle roof in the vicinity of the solar modules, is often such that the power supplied by the solar module with average solar radiation is sufficient to operate the fan while using the remaining energy to charge the vehicle battery. In general, therefore, this additional fan can be permanently in operation as long as sufficient energy is supplied by the solar modules; the activation of the blower of the air conditioner, which typically makes it impossible to recharge the battery even in high solar radiation and even discharges the battery, then takes place only after a defined period of time.
  • the average electrical power consumption of the further fan is between 5 and 20% of the average electrical power consumption of the blower of the motor vehicle air conditioning system.
  • the operating conditions described can be realized, that is, in particular, an operation of the further fan with simultaneous charging of the vehicle battery.
  • the average electrical power consumption of the further fan is between 20 and 40 W.
  • blower of the automotive air conditioning system is operated for a period of between 5 and 15 minutes. Operation of the blower over such a period provides significantly better conditions for the subsequent operation of the air conditioner than would be possible without the blower operation.
  • the compressor of the motor vehicle air conditioning system is operated over a period of between 10 and 20 minutes. After such an operating time of the entire motor vehicle air conditioning system, it can be assumed in most climatic conditions that a comfortable climate is encountered when entering the vehicle.
  • the invention is developed in a particularly advantageous manner in that the period over which the blower of the motor vehicle air conditioner is operated without the operation of the compressor as a function of the temperature and / or the solar radiation and / or the state of charge of the vehicle battery is selected as boundary condition (s).

  • the various parameters have various influences on the design of the method according to the invention.
  • a high temperature in the vehicle interior makes it necessary to carry out the process in an optimal manner, in particular with simultaneous existing solar radiation. If there is no solar radiation and there is still a high temperature, it can be assumed that the vehicle can be brought to a lower temperature with less energy consumption.
  • the state of charge of the vehicle battery is to be considered in any case, in particular with regard to the distribution of the stored energy to the various operating conditions and in view of the fact that in any case a sufficient amount of energy must remain to start the vehicle easily.
  • the operation of the compressor takes place over a predetermined period of time and / or a period of time which is selected as a boundary condition (s) as a function of the temperature and / or the solar irradiation and / or the state of charge of the vehicle battery.

  • step SO1 it is first checked whether there is an energy gain due to solar radiation. If this is not the case, then it remains at a repetition of this review. However, if there is an energy gain due to solar radiation, the low-power blower 18 can be switched on in step S02. This can be done right after the

As a criterion for the early commissioning of the vehicle, for example, a received signal a remote control or a preselected time for the stationary air conditioning can serve. If it is determined that the start-up of the vehicle is imminent, the air conditioner is subsequently turned on for 10 minutes (step S04).
