Energy Efficiency incl. Circular Economy

A New Standard Contributes to Improving the Energy Efficiency of Jet Fans

When talking about energy efficiency, one of the most overlooked appliances is fans. Fans of all types are used for ventilation and air conditioning, for process engineering, and agriculture. Their energy use has been calculated as nearly 20% of total worldwide energy usage. To ensure that the fan performance characteristics are common throughout the world, a series of standards has just been developed by ISO and adopted by CEN.

 

Among these, the recently published EN ISO 12759-5 'Fans-Efficiency classification for fans - Part 5: Jet fans' establishes a classification of fan efficiency for all jet fan types driven by motors with an electrical input power range from 5,5 kW to 155 kW. Jet fans are used for producing a jet of air in a space, unconnected to any ducting. They find applications in the control of quality of air in vehicle and train tunnels, as well as in enclosed car parks, and their use has become increasingly popular (from EN ISO 13350:2015 'Fans - Performance testing of jet fans').

This document was prepared by Technical Committee ISO/TC 117 'Fans', in collaboration with the CEN/TC 156 'Ventilation for buildings', whose Secretariat is held by BSI, the British Standards Institute.
