Therefore, before construction, it is necessary to calculate the air volume to be exchanged. Calculate the volume of basement space. Calculate the required air flow to supply and air circulation speed. After knowing the wind flow, design appropriate and scientific technical drawings.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">When designing, it is necessary to pay attention to the size of the vents, the distance of the vents so that it is reasonable. Usually the air inlets and air supply are arranged on the basement floor. The distance between the doors of the air inlet\/air supply branches is from 3 to 6m. So that the air supply can be distributed to the required areas.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">The vent area depends on the previously calculated air flow. Calculate the wind speed from 1 to 3m\/s to ensure low noise.<\/span><\/p>\n<h3 id=\"ftoc-heading-13\" class=\"ftwp-heading\"><span class=\"ez-toc-section\" id=\"2_Selection_of_construction_and_installation_locations\"><\/span><b><span style=\"vertical-align: inherit;\">2.

Requires the system designer to calculate the location of the fan, duct, and air outlet so that it is reasonable.<\/span><\/p>\n<p><span style=\"vertical-align: inherit;\">It is not recommended to design and install industrial fans in locations where many people pass by. The fan should be installed higher or lower than the head, avoid placing the fan in the head-level position. Because the suction and blowing force from industrial fans is very strong, causing discomfort and affecting human hearing.<\/span><\/p>\n<h3 id=\"ftoc-heading-14\" class=\"ftwp-heading\"><span class=\"ez-toc-section\" id=\"3_Make_sure_the_power_supply_is_stable\"><\/span><b><span style=\"vertical-align: inherit;\">3.

Each type of industrial fan product often has different parameters. Therefore, when installing, it is necessary to choose the right equipment by carefully studying and reading the specifications of each product.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_basement_ventilation_options_are_there\"><\/span><strong><span style=\"vertical-align: inherit;\">What basement ventilation options are there?<\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"vertical-align: inherit;\">Some basement ventilation options most often chosen by investors today include: Natural ventilation and mechanical ventilation. Specifically:<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Natural_ventilation\"><\/span><span style=\"vertical-align: inherit;\">1. Natural ventilation<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"vertical-align: inherit;\">Natural ventilation is applied in the basement with a special air intake window in a large building. These windows are capable of opening and closing at will, evenly spaced, facing each other in the direction of the natural wind to catch the wind in the best way.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Mechanical_ventilation\"><\/span><strong><span style=\"vertical-align: inherit;\">2. Mechanical ventilation<\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"vertical-align: inherit;\">Mechanical ventilation is also known as forced ventilation. Simply put, through the use of industrial exhaust fans in combination with ventilation systems and air vents to create ventilation gaps. However, the system capable of sucking or both supplying and sucking air will be affected by the basement structure and the cost of the building owner.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_principle_of_operation_of_the_ventilation_and_cooling_system_for_the_basement\"><\/span><strong><span style=\"vertical-align: inherit;\">The principle of operation of the ventilation and cooling system for the basement<\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"vertical-align: inherit;\">The exhaust fan will suck the dust and harmful gases in the basement and discharge it to the outside through the pipeline. When the exhaust fan sucks in air, because in the closed cellar, there is a main pressure difference so the outside air will be sucked in to balance the air volume. According to this principle of operation, the air in the basement is always changed.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Choose_the_right_basement_exhaust_fan\"><\/span><strong><span style=\"vertical-align: inherit;\">Choose the right basement exhaust fan<\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"vertical-align: inherit;\">As mentioned above, the selection of equipment is extremely suitable. They contribute to the efficiency of the basement ventilation system. Currently, there are popular types of fans installed for basements as follows:<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Jetfan_ventilation_fan\"><\/span><strong><span style=\"vertical-align: inherit;\">1. Jetfan ventilation fan<\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"vertical-align: inherit;\">Jetfan is a specialized fan for basement ventilation. They have the effect of repelling the wind to help bring out hot gases, dirt, and harmful gases in the basement. With 2 sound-absorbing heads, the jetfan fan operates smoothly without affecting other activities.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Axial_fan\"><\/span><strong><span style=\"vertical-align: inherit;\">2. Axial fan<\/span><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"vertical-align: inherit;\">Axial fans are the most popular industrial ventilation fans today. They have the effect of ventilation, cooling and air circulation. Suitable for installation in basements. With large flow, axial fans have the ability to cool large spaces.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Centrifugal_fan\"><\/span><strong><span style=\"vertical-align: inherit;\">3.
