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

Nygard Adam, Bartoszewicz Jarosław

Combustion Engines

2020

R. 59, nr 4

15--20

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.

Characteristics of fans used in low-power boilers

Bartoszewicz J., Nygard A., Urbaniak R.

Journal of Power Technologies

2017

Vol. 97, nr 1

69--74

This paper presents the results of tests conducted in the Chair of Thermal Engineering of Poznan University of Technology dedicated to determining the efficiency of low-power barrel fans, which are used in low-power boilers. Operation parameters of fans produced for industry were checked with respect to the requirements of Directive 2009/125/EC of the European Parliament. The tests were used to determine the efficiency of fans and to compare them against values determined according to the European Directive. The test results are presented on graphs as functions of air volume flow. Those characteristics comprise distributions of total pressure, electric power absorbed by the motor, and fan efficiency. The results indicate that there is a need to develop new guidelines. They should concern those efficiencies of low-power fans which are not covered by Directive 2009/125/EC of the European Parliament.
