Method for performance testing and detection of natural ventilation filter device

Abstract

The invention relates to a method for performance testing and detection of a natural ventilation filter device. The method is characterized in that a testing apparatus is used for detecting the ventilation rate and the pressure difference, the particle size of the captured dust and the dust removing capability, the dehumidification efficiency and the rain-proof performance of the natural ventilation filter device through a low-speed wind tunnel testing apparatus; an exhaust fan is used as the power source for inducing air or feeding air; the inflowing air is filtered and purified after being rectified when the air flows into the testing apparatus at the rated pressure; the ventilation rate and the pressure difference before and behind the natural ventilation filter device, the particle size of the captured dust and the dust removing capability, the sprayed mist water and a rainwater spraying device are tested to obtain the corresponding data; and the particle size of the dust captured by the device is tested by a digital differential pressure gauge, a digital dust concentration testing instrument, an optical microscope and a humidity meter to observe whether or not water remains in a transparent organic tube. The method is simple, reasonable and effective.

Description

technical field [0001] The performance test and detection method of a natural ventilation filter device of the present invention relates to the natural ventilation filter equipment used for indoor and outdoor air pollution of civil buildings, the ventilation volume and pressure loss, the particle size of the captured dust, the dust removal ability, and the dehumidification. Efficiency, rainproof performance testing equipment and testing methods, so as to meet the products used in the field of building energy saving and environmental protection. Background technique [0002] The indoor air quality of civil buildings is closely related to human health. Due to the wide application of building decoration materials and chemical adhesives, the sealing performance of buildings has been improved, and it has also caused insufficient indoor ventilation and air exchange, making it difficult for indoor turbid air to be discharged. Indoor air pollution, including: formaldehyde, benzene ...

AI Technical Summary

Problems solved by technology

If the windows are not opened, it is necessary to maintain indoor ventilation at all times, realize low-carbon energy saving, and at the same time reduce the impact of indoor and outdoor air pollutants on a healthy house. This kind of ventilation equipment and system technology has not yet appeared, let alone Its corresponding test equipment and detection method and the technical standard of relevant industry; Therefore, it is necessary to develop a kind of natural ventilation filter device for civil buildings, and the performance test and detection method of natural ventilation filter device, so that buildings can realize 24-hour The indoor and outdoor ventilation system realizes building energy saving and low carbon emission, the purpose is to keep indoor and outdoor air pollution and diseases away from human health
