With the launch of the outdoor LCD advertising player market, more and more digital sign manufacturers will turn to the outdoor advertising player market. The outdoor cabinet is directly under the influence of the natural climate and is made of metal or non-metallic materials. It does not allow unauthorized operators to enter the cabinet. It provides outdoor physical working environment and security system equipment for wireless communication sites or wired network site workstations . The control cabinet air conditioner can adjust the temperature, relative humidity, and flow speed of the air in the electrical control cabinet. The difference between the cabinet air conditioner and the ordinary air conditioner is the structure, the object of service, and the use environment.

The main difference between outdoor advertising machines and indoor products is the difference in the use environment. Outdoors, wind and rain must be considered, exposure in summer, and freezing in winter. Therefore, in the aspects of heat dissipation, dustproof, moisture-proof (water), etc., professional design is required. The brightness of the outdoor advertising player screen is generally above 1500 Nit, which means that the heat of the advertising player increases, plus the solar radiation, so it needs special cooling system. Industrial precision air conditioning is the most suitable environmental control system for outdoor advertising machines. It has the integrated functions of cooling and heating, which can completely isolate the internal working environment of the advertising machine from the outside world, completely avoid the internal dust and humidity, and ensure the screen of the outdoor advertising machine And the motherboard is always in the best working environment.

However, if the advertisement is not used properly, the air conditioner will not achieve the desired effect. According to the advertisements of the machine manufacturers with a lot of work experience, we found that the more common problems are:

1. The manufacturer is worried about the waterproofness of the air conditioner, often making the air inlets and air outlets on the external circulation of the air conditioner small, or the angle of the blinds is too large, resulting in insufficient effective ventilation area. This will result in poor cooling of the air conditioner and a severe discount on the cooling capacity.

2. The internal and external circulation of the air conditioner is not isolated, not only the cooling effect is poor, but also the problems of dust and humidity.

3. The internal and external circulation outlets and the return air outlet are short-circuited.

How to avoid these problems, as a professional outdoor advertising air conditioner manufacturer, Suzhou Langji Technology Co., Ltd. recommends as follows:

1. The effective ventilation area reserved for the external circulation of the air conditioner by the advertising machine shell is not less than 1.5 times the actual area of the air inlet of the external circulation of the air conditioner.

2. The external circulation and internal circulation of the air conditioner need to be completely isolated. The external circulation inlet and outlet ducts correspond to the external circulation of the advertising machine to seal the air outlet.

3. The air duct design ensures the direction of the air conditioner and the temperature in front of the screen is not higher than 50 ℃.

Suzhou Langji Technology Co., Ltd. is a professional engaged in the development, production and sales of precision industrial cabinet air conditioner and outdoor air conditioners for advertisements. It has launched more than a dozen air conditioners specifically for the use of outdoor advertisements, completely solving the problems of heat dissipation, heat dissipation, dust prevention and moisture resistance problem. At present, the mainstream outdoor advertising companies on the market basically use air conditioners of outdoor advertising machines.
