We all know that it is necessary to install air ducts and air outlets for evaporative air cooler cooling system.  In order to transport the cool fresh air to the work positions that need to be cooled. Then we should think how high the vertical distance between the air outlets of the air cooler and the ground is the most reasonable. The design of the air outlet is the most comfortable and cool for people to blow, and it is more ergonomic, so that the cool fresh air will be comfortable for workers.

The design of the air outlet is actually related to the installation scheme of the air cooler. If the air cooler is side wall hanging and direct blowing solution is adopted, the large air outlet 750*400mm is generally used , though the vertical height of the air outlet from the ground It is best between 2.5-3.5 meters, because the large air outlets are all wind-driven air outlets, so in order to ensure a better cooling effect, sometimes the size and height of the air outlets will be adjusted according to the cooling environment during design; if the position cool scheme is adopted. At this time, it is necessary to make an air supply duct, and then open a small air outlets 270*250 at the bottom and sides of the air supply duct. The small air outlet will not keeps swinging like a wind-operated. Generally, the wind speed, pressure, and air supply direction are manually adjusted according to the conditions of the personnel at the workplace during use. Therefore, the best design height for the air duct is generally 2.0- 2.5 meters is the most reasonable. If the height is too low, it is easy to hit the head and affect the normal passage of people. What if the height is too high! The cooling effect will not be optimal;

Of course, in addition to the height design of these two types of air outlets, there is another type of installation with holes in the roof. This installation method is generally made into T-shaped pipes, direct blowing, and mushroom head air outlets. The size of the air outlet of the T-shaped pipe It is almost the same as the height design and fixed-point post cooling scheme, but the design height of direct blowing and mushroom head outlets is different, because the machine is installed on the roof, and the air is directly introduced to the workshop through the straight pipe, without any wind loss, in fact The wind pressure and wind speed are very high. The average height of steel structure iron tile factory buildings is more than 10 meters, so the vertical height from the ground should be 5-8 meters, which is more reasonable.

The above design standards for the air outlet of the air cooler are only reference data for the design of general-purpose main units. When the air volume selection of the main unit is different, the size and design height of the air outlet must also be adjusted. Therefore, at this time, professional environmental protection air-conditioning project installation and design personnel are required to go to the site to investigate the environment, and then make an overall plan for the installation environment and workshop environment, in order to achieve the best improvement of the environmental protection air-conditioning cooling project.
