Mixing ventilation, also known as mixing type ventilation or general ventilation, is a method used to dilute and remove contaminants from a space by introducing fresh air and exhausting stale air. The fundamental principle is to mix the incoming fresh air with the existing air in the room, thereby reducing the concentration of pollutants like heat, moisture, or airborne contaminants to acceptable levels. This type of ventilation is characterized by the introduction of supply air at relatively low velocities and often at multiple points throughout the space, allowing for a more uniform distribution and dilution of contaminants.

The effectiveness of mixing ventilation depends on several factors, including the rate of air exchange (how often the entire volume of air in the room is replaced), the location of supply and exhaust air inlets and outlets, and the patterns of air movement within the space. Good mixing ventilation aims to ensure that fresh air reaches all occupied areas and effectively dilutes pollutants before they can accumulate to harmful concentrations. It is often employed in large, open spaces such as factories, warehouses, and auditoriums where localized exhaust might be impractical or insufficient. While it can be a cost-effective solution for general air quality improvement, it may not be suitable for controlling highly localized or high-concentration sources of pollution.
