Abstract: A device for determining a temperature in a passenger compartment of a vehicle comprising a sensor unit for detecting infra-red radiation and a temperature determining unit. The temperature determining unit may be configured so as, in dependence upon the measurement data provided by the sensor unit, to determine a surface temperature of a predetermined object located in the vehicle passenger compartment and, from the determined surface temperature of the object using a first functional relationship, to determine an air temperature in the vehicle passenger compartment. The temperature determining unit may be configured as an alternative or in addition thereto so as, in dependence upon the measurement data provided by the sensor unit, to determine a surface temperature for at least one passenger compartment occupant, and from the determined surface temperature using a second functional relationship to determine a measurement for the level of personal comfort.

Abstract: A cold and/or heat accumulator with a plurality of carrier elements (10) which are charged with a cold or heat storage medium, and with a heat exchanger (12) which is designed to have a heat transfer medium flow through it in order to cause heat exchange between the cold or heat storage medium and the heat transfer medium. The heat exchanger (12) has at least one serpentine hollow section (14), and at least at least one carrier element (10) is provided between the legs of at least some of the loops of the serpentine hollow section. In a process for producing the cold and/or heat accumulator, the height of the carrier elements is coordinated to a distance between the legs of the at least one loop such that, after a force-fit connection is formed between the serpentine hollow section and the carrier elements.

Abstract: A process for delivering a cold or heat storage medium into a carrier material, in which the carrier material is located in a container which can be at least partially evacuated. The process includes the steps of: a) placing the carrier material in a container made of film material, b) at least partially evacuating the container made of film material, and c) delivering cold or heat storage medium to the at least partially evacuated container made of film material so as to saturate the carrier material with the cold or heat storage medium.
