Description

Technical Field

[0001] This utility model relates to the field of air pollution ventilation technology, specifically a ventilation structure for preventing air pollution in enclosed spaces. Background Technology

[0002] Ventilation equipment is necessary to prevent air pollution in enclosed spaces. Ventilation equipment is a device that achieves air exchange through natural or mechanical means, primarily used to regulate indoor air quality and meet the ventilation needs of industrial production, medical facilities, and agriculture. Its core functions include introducing fresh air, removing pollutants, and controlling temperature and humidity. It can be divided into two categories: natural ventilation (relying on temperature differences or wind power) and mechanical ventilation (using fans for forced air exchange). Mainstream equipment includes roof ventilators, negative pressure fans, evaporative coolers, and evaporative cooling systems, some of which integrate air purification, intelligent frequency conversion, and multi-mode switching functions. Ventilation can also be categorized by scope into general ventilation and local ventilation. General ventilation, also known as dilution ventilation, exchanges air throughout the entire space. Local ventilation directly collects polluted air at the point of origin and exhausts it outdoors, or directly supplies fresh air to a specific area. Local ventilation has advantages such as good ventilation effect and energy saving. However, current ventilation structures for preventing air pollution in enclosed spaces are not convenient to install, making installation time-consuming and labor-intensive. Utility Model Content
