One, less than 20 squares of led display
1. For the north of Guangdong Province, the led display within 20 square meters does not recommend the use of air conditioning. If conditions permit, the use of two small fans is sufficient.
2 , some cities in the South: Guangdong, Guangxi, Hainan, Wuhan, Chongqing and other places need to install two fans is enough, the diameter of the fan is about ** 500mm , depending on the size of the installation space.
   Second, the display area of ​​more than 20 square meters
1. If your big screen installation position is against the wall, it depends on how much you can spit out on the big screen. If you can protrude one meter from the wall, it is recommended to select the fan according to the size of the area. The fan installation position is on the screen. The top side of the side is arranged in turn. If you buy a display with an 80- square- meter ph16 outdoor led full-color screen , it means that you need 6 fans with a diameter of 600mm . The fan is pumping outside. The kind, and when installing the fan, it is necessary to ensure that there is a net inside to prevent the technicians who repair the large screen from sucking other things into the adult body when repairing the big screen, in order to protect the adult body from injury, in order to be waterproof, to be on the outer aluminum composite panel. The fan outlet is fitted with aluminum shutters. The large screen on the wall can also be equipped with air conditioners. It is necessary to ensure that the main unit of the air conditioner has a position and does not affect the overall appearance of the wall. The choice of air conditioning is required. The most commonly used air conditioners are 1.5P , 2P and 3P . The air conditioning is calculated for 12 square 1P in the northern city. The southern city uses 9 square 1P air conditioning. If the area of ​​the LED outdoor large screen is relatively large, the air conditioner will go directly to the manufacturer to customize it. If the area is not large, it is necessary to go to the store to buy it, but the large screen cooling air conditioner has the call compensation function.
2 , if the installation of the led large screen is to use the column, it is best to use a fan to dissipate heat, the fan is mounted on the back of the large screen aluminum composite panel, preferably up, made into the form of blinds for rain Rain does not enter the large screen. If it is a double column, it will open several louvers in the middle of the double column. This window is the air inlet, and the fan above is the exhaust port, thus forming a complete air convection to make the heat dissipation effect. better. If you require air conditioning, this is no problem, the cost of purchase and the cost of use will increase, and the heat dissipation effect will be worse than that of the fan. This is our experience. There is another problem. If you want to install air conditioners, one of the issues that must be considered is where the external machine is installed, whether it is hung on the column or hanging on the back, whether it can ensure the appearance of beauty.
     According to experience, our large-screen heat dissipation, the wall is generally used for air conditioning cooling, the general use of the column is the fan cooling, if you require good cooling, the fan is the most economical and cost-effective choice
