The article is focused on the infrared measurement method in the air in small closed areas. This method is based on the visualization of temperature fields on an auxiliary material which is inserted into the non-isothermal air flow in a research area. In small closed spaces where is impossible to put the measuring equipment due to various reasons, it is necessary to visualize the temperature fields through a window. This window must be permeable for infrared radiation of known properties, especially the transmissivity. As an auxiliary material for the visualization of temperature fields in these experiments, the ordinary office paper with high emissivity value was chosen and the viewing window was made of a polyethylene. The presented method for the measurement of temperature fields in the air can be applied mainly in closed spaces where is difficult to situate the infrared camera (due to field of view), in spaces where the infrared camera restricts the flowing air or where is aggressive or too hot environment (a potential damage of infrared camera), etc. In this article the parameter analysis, which is important for a particular application, is performed and an example of temperature fields measurement in closed space is presented. This method can be used in cooling and heating design of means of transport, mostly for cabins of cars and trucks.
