The air volume and wind pressure test device adopts a multi-nozzle air chamber structure, and the corresponding nozzle can be selected according to the measured flow rate to accurately measure the air output of the combined air conditioning unit (horizontal air output and top air output) with an air volume of less than 13,000-13,000 air volumes. Related technical data such as static pressure, air volume and power consumption. In order to adapt to a wider test range, auxiliary fans, multi-nozzle measurement, and air valve coordination are adopted. Equipment operation adopts programmable controller + human-machine interface control. The interface is intuitive, convenient and reliable. The measured values are processed and archived by computer. The test report is automatically printed. The test results and test data can be analyzed. Written using LABVIEW.

1. The group adopts the frequency conversion starting method. The high-frequency power meter is used to test the power value after frequency conversion to improve the accuracy.

2. For direct air outlet type: single air outlet maximum size: 1790mm × 1790mm,

                                          Maximum size of double air outlet: 1120mm × 1423mm,

    For the wind chamber type: single outlet maximum size: 2640mm × 1340mm.

This laboratory is the largest combined air-conditioning air volume and air pressure test device in the industry.
