Description

Technical Field

[0001] The utility model relates to the technical field of air outlet pipes, in particular to a pressure-adaptive variable air volume air outlet. Background Art

[0002] A fresh air system is a system that provides fresh air indoors while simultaneously exhausting contaminated air outdoors. It typically includes a fan, an inlet duct connected to the fan's air inlet, and an outlet duct connected to the fan's air outlet. Currently, many villas, office buildings, workshops, and factories use fresh air purification systems to provide a clean indoor air environment. Indoor air purifiers typically purify air by circulating indoor air. Air is drawn in through the purifier's air inlet and, after passing through various filters, is discharged through the exhaust vents.

[0003] Traditional air vents are only the end parts of the ventilation system that guide the airflow and manually adjust its size. They cannot be adjusted automatically. However, manual adjustment of the wind direction may affect the air volume (if the air volume is not adjusted, the air intake of the air vent will continue to be constant), which will affect the replacement of indoor air. In addition, when the pressure is lower than the indoor pressure, if the air outlet is not closed, the indoor air will flow outdoors, affecting the indoor environment.

[0004] Therefore, a pressure-adaptive variable air volume tuyere is proposed, which is upgraded and modified based on the device to solve these shortcomings. Utility Model Content
