Definitions

  • Air conditioning systems in vehicles are on the rise. The reason for this is not only the need for more travel comfort, but also for more security.
  • a study by the TÜV has shown that increasing the internal temperature of a vehicle from 25 ° C to 35 ° C is equivalent to reducing the ability to drive to a blood alcohol level of 0.8 per thousand.
  • An air conditioning system consumes an average of 0.6 liters of fuel per 100 km during operation.
  • the emissions of CG ⁇ NOx increase accordingly Vehicle pollutants.
  • Cooling in the vehicle is necessary when there is an abundance of energy outside the vehicle, much of it as radiation.
  • DE 37 11 180 AI relates to collapsed photovoltaic elements on the roof, which can be opened to either side of the vehicle when standing, thus doubling the receptor surface of the photovoltaic elements. More than doubling could be achieved using the same system.
  • DE 296 18 379 UI has the object of a solar-powered "parking ventilation system" with which a ventilation fan is operated by photovoltaic elements when parking. It should at least reduce the accumulation of heat when stationary.
  • DE 39 32 526 AI has a mountable car canopy, which on the one hand causes shading of the vehicle by "roller blinds" in park operation, but also operates the vehicle blower by means of a small solar cell in order to counteract heat accumulation in the vehicle by ventilation.
  • sliding roofs with an integrated photovoltaic element are known as so-called “solar parking ventilation” in order to drive the vehicle fan when stationary and thus to lower the interior temperature when parking in the sun.
  • the Audi A-8 with a 25 watt solar generator can achieve an interior temperature of approx. 42 to 45 ° instead of a temperature of 58 to 60 ° C in the same vehicle without “solar parking ventilation". This is still far from the "feel-good temperature of 23 ° C, determined by medical experts.
  • solar-powered cooling devices will not be able to achieve a noticeable increase in the low outputs described, and even only when the vehicle is stationary. This would require photovoltaic elements with much higher efficiencies, which are not available for the time being.
  • the present invention relates to the further development of a system for air conditioning with which drive energy for cooling or air conditioning systems is obtained in vehicles by converting solar energy.
  • Cooling using solar energy not only reduces vehicle fuel consumption and polluting emissions, it also offers a number of other advantages:
  • the air conditioning system can also run during parking and keep the vehicle cool. Only when the supply of solar energy e.g. at dusk falls below certain limits or the vehicle e.g. is parked in a garage, the function of the air conditioning comes to a standstill.
  • the solution according to the invention also brings great advantages to freight vehicles that transport temperature-sensitive cargo.
  • Their roof areas offer large areas to absorb convertible solar energy.
  • the air conditioning systems can be operated in an environmentally neutral way by converting solar energy, with sufficient thermal insulation even when stationary;
  • the conversion of solar energy to drive energy from air conditioning systems is useful for cooling in summer.
  • the opportunities to convert solar energy are limited in low-sun seasons. Cooling is then not necessary, rather heating.
  • converted solar energy can be used as additional heating if the waste heat from the Vehicles for heating the interior are no longer sufficient. Since the energy supply is inherently low in the low-sun season, the concept according to the invention is all the more dependent on the combination with adequately dimensioned thermal insulation.
  • the units preferably photovoltaic, for converting solar energy into drive energy for air conditioning systems and heating systems can be integrated into the large vehicle parts that are particularly exposed to the sun. These are primarily the roof, the bonnet and the tailgate, if not exclusively. But photovoltaic elements can also be integrated in window areas, especially in the side window and rear window.
  • elements for converting solar energy should also be designed to be assembled and disassembled in a similar manner, e.g. Hardtops or ski offers.
  • Hardtops or ski offers When combined with thermal insulation, foldable, unfoldable or similar enlargements of the photovoltaically effective surface, which cannot be operated while driving, are unnecessary. Operation is possible both when driving and when stationary. This makes it possible to only feed these units when they are actually needed, e.g. in the sunny time.
  • Energy not used by the air conditioning / heating is to be fed into the general energy system of the vehicle in order to supply / supply auxiliary units and thus reduce the generation of energy from fossil fuels.
  • the vehicle can be air-conditioned without stressing other vehicle units.

Abstract

L'invention concerne un véhicule à moteur avec système de chauffage et/ou de climatisation présentant des cellules solaires photovoltaïques qui alimentent les dispositifs de chauffage et/ou de climatisation du véhicule. En outre, et de façon complémentaire, l'habitacle du véhicule est thermo-isolé de sorte que l'énergie fournie par les cellules solaires photovoltaïques suffit, au moins dans une large mesure, à assurer une climatisation constante pendant le trajet.
