31、the fossil fuels in use. There is also a belief that climatic change is due to an increase in the levels of carbon dioxide in the atmosphere. This has lead to many nations reviewing methods of energy generation and usage. Therefore, there is a need to promote energy efficiency in order to maintain e
32、conomic growth. This requires better selection of equipment by users and better design of this equipment by manufacturers. Fans of all types are used for ventilation and air conditioning, process engineering (drying, pneumatic conveying), combustion air supply and agriculture, etc. Indeed, the energ
33、y usage by fans has been calculated as nearly 20 % of worldwide demand. The fan industry is of a global nature, with a considerable degree of exporting and licensing. To ensure that defined fan performance characteristics are common throughout the world, a series of International Standards has been
34、developed. It is the belief of the industry that there is a need for the recognition of minimum efficiency standards. To encourage their implementation, a classification system is proposed which incorporates a series of efficiency bands. With improvements in technology and manufacturing processes, t
35、he minimum efficiency levels can be reviewed and increased over time. This International Standard can be used by legislators or regulatory bodies for defining future energy saving targets.
