摘要： A method and apparatus for determining the total flow rate in a ventilation installation with a free suction fan (15) are described. The flow rate is determined by measurement of the local pressure at at least one measurement point in the vicinity of the inlet opening of the free suction fan. A measurement probe (20), open at one end only, is used as measurement means, and oriented with its longitudinal axis in the inflow direction. The measurement point (20a) is situated axially inside an outer radial plane (B), which is located at an axial distance (a) outside an inner radial plane (A). The measurement point is located adjacent to said inner radial plane (A), though always in the narrowest section of the fan inlet. In this way there is obtained good measurement accuracy within a large flow range.

摘要： The present invention relates to an air treatment apparatus (1) having a house (2) housing a suction fan (9). The house (2) has walls (3-8). Air flows through the front wall (5), passes a lateral wall (7 and 8 respectively) and enters into the fan inlet (11) and leaves the house through an outlet (12) in the rear wall (6). With a view to prevent rotation of the air, which flows into the apparatus, guide means (16) are mounted in the space (13) in front of the fan inlet (11), which guide means (16) are made in the form of a triangular plate, the small sides (17, 18) of which extend to the rear wall (6) and one of the lateral walls (7) respectively and the hypotenuse of which (20) lies outside the greater portion of said space (13).
摘要翻译：本发明涉及一种具有容纳吸风扇（9）的房屋（2）的空气处理设备（1）。房子（2）有墙壁（3-8）。空气流过前壁（5），通过侧壁（7和8）并进入风扇入口（11），并通过后壁（6）中的出口（12）离开房屋。为了防止流入设备的空气的旋转，引导装置（16）安装在风扇入口（11）前面的空间（13）中，该引导装置（16）以三角形板的小边（17,18）分别延伸到后壁（6）和一个侧壁（7），斜边（20）位于所述空间的较大部分的外侧（ 13）。
