Abstract
The article deals with the temperature fields measurement of air using the Jenoptic Variocam infrared camera inside the car Škoda Octavia Combi II. The temperature fields with the use of auxiliary material with a high emissivity value were visualized. The measurements through the viewing window with a high transmissivity value were performed. The viewing windows on the side car door were placed. In the rear car area, the temperature fields of air on the spacious sheet of auxiliary material were visualized which is a suitable method for 2D airstreams. In the front car area, the temperature fields in the air were measured with the use of the measuring net which is suitable for 3D airstreams measuring.

Summary
The temperature fields measurement by the infrared camera is very effective and quick way to measure the temperature. The infrared camera allows measuring the static conditions and the monitoring of dynamic processes but in the comparison to other methods of measurement (e.g. the measurements of the net of thermocouples, interferometry, planar laser-induced fluorescence, etc.) is more suitable by usage outside the laboratory. The temperature visualization by the infrared camera allows the deeper understanding and indentifying connections in the measuring processes during the monitoring of a variable temperature field. This method of measurement of temperature fields in the air can be used in many fields of heating and cooling [3]. With the use of the viewing window the method can be applied for measurements of temperature fields in small closed spaces, such as in cabins of means of transports, air-conditioning units, or in areas which is not suitable for operation staff and others [4]
