Abstract
Abstract An automotive vehicle has an air compressor; a compressed tank for storing air compressed by the compressor; and a system for selectively releasing compressed air from the tank into the vehicle's passenger compartment to cool it. Preferably the vehicle includes a ventilation system and the compressed air is released into the ventilation system's air passageways. If the vehicle include a traditional air conditioning system using the evaporation of refrigerant to cool air, the release of compressed air can be used to provide cooling until a sensor indicates the traditional air conditioning system is capable of providing sufficient cooling. Preferably a radiator is located in the line between the air compressor and the compressed air tank to transfer heat away from the compressed air before it is stored in the tank. It is also preferred that controls in the vehicle's passenger compartment enable a passenger to control the release of the compressed air. Preferably the air compressor is turned on and off as a function of the pressure in the air tank, so the pressure in the tank tends to stay above a certain level. In some embodiments a plurality of compressed air tanks are provided with can separately have compressed air supplied to, or released from, them. Preferably the release of compressed air can be automatically stopped when a sensor detects that air temperature has dropped below a given level.
