Evaluation efficiency of low-power fans used in the means of transport

The article presents test results on low-power fans used in the means of transport. Fans evaluation was in the context of energy efficiency. Interest in scientific topics related to low-power fans has its source in the reports of the Chief Inspector of Environmental Protection on the state of the natural environment in Poland and European Union reports assessing our natural environment. The goal of the article is to compare experimental results with Minister of Economy Regulation of March 11th, 2014, which introduces changes in accordance to European Parliament and Council Directive 2009/125/WE, with regard to ecodesign requirements for fans driven by motors with an electric input power between 125 W and 500 kW.
