Multi-working-condition adjustable vertical vortex ventilation testing device

Abstract

The invention discloses a multi-working-condition adjustable vertical vortex ventilation testing device which comprises an exhaust supporting frame and further comprises a plurality of air supply mechanisms, a pollution source item module and an exhaust mechanism, the exhaust mechanism is detachably installed on the exhaust supporting frame, the air supply mechanisms and the pollution source item module are arranged in the air exhaust supporting frame and are positioned right below an air exhaust port of the air exhaust mechanism; the plurality of air supply mechanisms are movably and uniformly arranged around the pollution source item module, and the plurality of air supply mechanisms are hinged to the pollution source item module; the air supply mechanisms which are uniformly distributed are arranged in the air supply device, so that not only is a vertical vortex formed, but also air supply at different angles can be realized by moving the air supply mechanisms; in addition, the pollution source item module can simulate pollutants at different temperatures; and the technical problems that in a current vortex ventilation testing device, working condition adjustment is difficult, flexibility is low, and a pollution source cannot simulate high-temperature pollutants are solved.

Description

technical field [0001] The invention belongs to the field of ventilation, and relates to a ventilation detection device, in particular to a multi-working-condition adjustable vertical vortex ventilation testing device. Background technique [0002] In today's society, the rapid economic development is often accompanied by the emergence of environmental problems, especially the indoor air of industrial buildings and civil buildings needs to be optimally controlled to ensure the normal work, rest and production of residents or workers. Local ventilation is an important means of optimal control of indoor air, but usually requires high energy consumption to achieve better environmental control effects. Vortex ventilation is a new type of ventilation method. Compared with traditional ventilation methods, it can achieve better environmental control effect with lower energy consumption. [0003] Before a new ventilation method is put into production use, it is often necessary to t...
