European Union energy label

A new energy label, introduced in 2010, is based on the energy efficiency index (EEI), and has energy classes in the range A+++ to D The EEI is a measure of the annual electricity consumption, and includes energy consumed during power-off and standby modes, and the energy consumed in 220 washing cycl For the washing cycles, a weighted mix consisting of 42% full-load cycles at 60 °C, 29% ....

Filter Efficiency

The pitfall of the filter efficiency of a nonwoven fabric for particles of the diameter between d p1 and d p2 is unacceptable but inevitable To design a nonwoven filter with high filter efficiency, nonwoven fabrics composed of fibres of more than one diameter is proposed 92 If a nonwoven filter is composed of multiple components of fibres, the filter efficiency of the nonwoven filter for ....

Air Filters

Air filters, and primarily those intended for ventilation of living and working spaces, are classified by efficiency in the CEN/EUROVENT classification given in Table 74Much depends, in their selection, on the degree of protection required and the volume of air to be treated Actual requirements can range from normal room protection to the supply of sterile air for critical processes and ....
