Description
Technical field
The present invention relates to a kind of filter, further relates to a kind of air-conditioning for being provided with the filter.
Background technology
Filter element can be used for removing the pollutant in a variety of applications.This class component can include one or more fibers
Net.The web provides the loose structure for allowing fluid (for example, gas, liquid) to flow through the element.Contained by fluid
Contaminant particle can be trapped by web.In the filter element including multiple webs, different nets can be designed as
Different functions is performed, it is possible thereby to take on a different character and property.For example, filter element can include being primarily designed as
The web (for example, efficiency net) of filtering contaminants and be primarily designed as provide mechanical integrity another web (for example,
Backing).
Permeability is related to the ability that web passes through fluid.It can be expressed as the time per unit under fixed pressure difference and pass through
The fluid volume of unit area web.Filter element including multiple webs can include the net with different permeabilities.
Such as, there is provided mechanical integrity but be typically not dependent on its strainability net (for example, backing) can be designed as have height
Permeability so that this kind of net does not reduce total permeability of filter medium.
Web can be folded into the fold of the clear-cut including point, and it increases web surface product, so as to
Improve total efficiency and performance.The web of pleat bad playing is likely to form round uneven fold when folding.It is this kind of not
Uniformity can fill up the space between fold, finally limit air flow, cause efficiency reduction and fluid flows through web
Resistance increase.Several properties of web can aid in its fold and can play well, including rigidity and thickness.Typically
Ground, it may be difficult to make the low web pleating of the high and thick degree of permeability, because this kind of Netcom is normal among other factors
May not have enough rigidity.
