[XAVIKE/Sevico] LCD splicing screen to explain the environment temperature and humidity, air conditioning requirements

The user may have noticed that the parameters of the LCD splicing screen will emphasize the environment temperature and humidity, but whether it is in the LCD splicing screen installation or use process, the surrounding environment temperature, humidity has not been valued by users! In fact, this is very Bad habits, because the liquid crystal materials currently used in LCD splicing screens are all thermotropic liquid crystal materials, which have their temperature range in use and storage. Once they exceed the specified temperature range, the liquid crystal materials will lose their liquid crystal state and will not work properly. , Sometimes it will damage the LCD splicing screen device, causing inconvenience and unnecessary loss to the user. The following is a detailed analysis of the requirements of the LCD splicing screen on the temperature and humidity and air conditioning requirements. 1. Temperature and Humidity Requirements The splicing display system has a good air conditioning environment and air convection within the maintenance channel, and at the same time, the condensation temperature of the splicing system will not cause condensation due to excessive temperature difference. The ideal working environment temperature of the splicing display system is 20Â°CÂ±5Â°C, and the ideal relative humidity is 30% to 70% without condensation. It is not allowed to generate a large temperature difference or a sudden change in wetness, and it is necessary to ensure a slow process of changes in temperature and humidity. 2. Air Conditioning Requirements The splicing system installation room can use the constant-temperature, constant-humidity air-bath type special air-conditioner under the condition, and the other can use the air-cooled split air conditioner (if there is a central air-conditioning system in the building, the corresponding ventilation equipment should also be configured so that The temperature is controlled between 15Â°C and 26Â°C). Requirements for air-conditioning design (more ideal): The air-conditioning ducts for the central air-conditioning in front of the display wall and the maintenance channel on the back of the display wall should be designed for the same air outlet and return air duct. All air-conditioning air outlets should be kept away from the mosaic display wall. About meters, and can not blow directly against the mosaic display wall; air conditioning switch splicing front and rear repair channel centralized installation of a place, in the use of air conditioning should be open or simultaneously closed air supply, to prevent forgetting a switch caused serious temperature difference . In addition, after splicing the display wall, no less than two extraction fans shall be added to the maintenance channel to inhale the air outdoors to ensure air circulation convection before and after splicing the display wall, so as to avoid the phenomenon of damage and dew condensation due to uneven heat and coldness of the display screen wall. In areas with high humidity, dehumidifiers should be installed in the equipment room to ensure that the relative humidity meets the requirements. It is worth noting that before the on-site installation of the LCD splicing display system, the air conditioning system and the fan at the installation point must be continuously operated for 5 days in order to ensure that the dust in the air-conditioning duct is cleared and the dust-free condition can be installed. construction.
