Outdoor Advertising Display Cooling: Fans vs Air Conditioning
Fan-Based Outdoor Advertising Display Cooling
Intelligent direct ventilation is used for heat dissipation, and the fan draws air from the outside into the inside of the machine for cabinet heat dissipation; the display does not go black under the outdoor ambient temperature of -20°C to +50°C, and the whole machine works normally; it adopts an axial flow fan or a centrifugal fan (depending on the model), and a matching fan speed control board to automatically adjust the fan speed by temperature sensing, saving energy and electricity, and extending the service life of the fan; a high-efficiency filtration system to isolate harmful dust from entering the machine, and the protection level of the whole machine reaches IP55. Advantages:
Relatively low cost/energy saving, less power consumption than air-conditioned models. Disadvantages: In summer, when the internal temperature of the digital signage display is high and the external ambient temperature is ≥5°C, the machine may have a black screen when the temperature in front of the screen is higher than 55°C. There is a lot of dust outdoors and it is easy to accumulate dust, so it needs to be cleaned frequently. Humid air cannot be completely prevented from entering the inside of the machine, and moisture-proofing cannot solve the problem. Outdoor advertising display cooling must account for solar load as well as ambient temperature.
Suitable for outdoor environments with temperatures ranging from -10℃ to +50℃ in all seasons Fan-based outdoor advertising display cooling depends on clean and controlled airflow.
Air-Conditioned Outdoor Advertising Display Cooling
The intelligent cooling and heating integrated cabinet air conditioning and temperature control can meet the normal operation of the LCD screen under the ambient temperature of -40℃~+55℃; it can automatically adjust the temperature by temperature sensing to ensure that the internal temperature of the machine is always within the range of 25±15℃; the patented heat dissipation system ensures that the LCD screen will not blacken under direct sunlight; the fully sealed design of the cabinet ensures that no dust enters the inside of the cabinet; the high-efficiency radiator, environmentally friendly refrigerant, high cooling capacity, environmental protection and energy saving.
Advantages: The internal temperature is set according to the needs, and the cooling and heating are integrated to keep the digital signage display always in the optimal working environment; the interior of the outdoor digital signage is completely isolated from the outside, completely solving the dust-proof problem; the air conditioner itself has a dehumidification function, and the internal space is isolated from the outside, which effectively solves the moisture-proof problem. Disadvantages: The cost is relatively high; the power consumption is slightly larger than that of the air-cooled model. Applicable to:
