1、稀釋通風

1. Dilution ventilation

稀釋通風又稱攙雜通風，即送人比室內汙染物濃度低的空氣與室內空氣攙雜，以此下降室內汙染物的濃度，抵達衛生標難。

Dilution ventilation, also known as mixed ventilation, refers to the process of mixing indoor air with air with a lower concentration of pollutants, in order to reduce the concentration of indoor pollutants and achieve hygiene standards.

2、置換通風

2. Displacement ventilation

在置換通風體係中，鮮美冷空氣由房間底部以很低的速度送入，送風溫差僅為2—4Y。送入的鮮美空氣因密度大而像水相同彌散悉數房間的底部，熱源導致的熱對流氣流使室內發生筆直的溫度禪度，氣流遲緩上升，脫節作業區，將餘熱和汙染物推向房間頂部，由設在頂棚上或房間頂部的排風口直接掃除。

In the displacement ventilation system, fresh and cold air is introduced from the bottom of the room at a very low speed, with a temperature difference of only 2-4Y for the supply air. The fresh air sent in is as dense as water and diffuses at the bottom of all rooms. The heat generated by the heat source causes a direct temperature rise in the room, causing the airflow to slowly rise and detach from the work area, pushing waste heat and pollutants towards the top of the room, which is directly swept away by the exhaust vents installed on the ceiling or at the top of the room.

室內空氣近似活塞狀活動，使汙染物隨空氣活動從房間頂部掃除，作業區根本處於送入空氣中，即作業區汙染物濃度約等於送人空氣的濃度，這是置換通風與傳統的稀釋全盤通風的很大別離。在通風麻豆视频官网中，顯著置換通風的通風成效比稀釋通風要好。

The indoor air moves in a piston like manner, allowing pollutants to be swept away from the top of the room along with the air movement. The working area is fundamentally in the incoming air, meaning that the concentration of pollutants in the working area is approximately equal to the concentration of the incoming air. This is a significant difference between displacement ventilation and traditional dilution ventilation. In ventilation ducts, significant displacement ventilation has better ventilation effectiveness than dilution ventilation.

3、片麵通風

3. One-sided ventilation

片麵通風便是欺詐片麵氣流，使片麵當地不受有害物的汙染，構成優異的空氣環境。

One sided ventilation refers to deceiving one sided airflow to prevent local pollution from harmful substances and create an excellent air environment.

片麵通風體係分為片麵送風和片麵排風兩大類。片麵排風是將汙染物當場捕集、淨化後排放室外。片麵送風是將始末處理的、契合要求的空氣送到片麵作業當地，以確保片麵區域的空氣條件。片麵通風辦法作為確保作業和生計環境空氣品性、防備室內環境汙染的技藝對策應優先研究。

The one-sided ventilation system is divided into two categories: one-sided air supply and one-sided exhaust. One sided ventilation is the process of capturing and purifying pollutants on the spot before discharging them outdoors. One sided air supply is the process of delivering air that meets the requirements from the beginning to the end to the local area of one-sided operation, in order to ensure the air conditions in the one-sided area. The one-sided ventilation method should be given priority research as a technical countermeasure to ensure the air quality of the work and livelihood environment, and to prevent indoor environmental pollution.
