Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of temperature and humidity monitoring, and specifically relates to an intelligent temperature and humidity monitoring and adjusting device for clean workshops. BACKGROUND

[0002] In the environmental control of clean workshops, temperature and humidity adjustment is the core link to ensure the stability of production processes and product quality. Traditional technologies mostly adopt temperature and humidity monitoring schemes with single detection points, such as directly controlling air conditioners or humidifying equipment through indoor sensors. Such systems have problems of response lag and low adjustment efficiency, and it is difficult to achieve precise control, especially when there is a deviation between the temperature and humidity of the air outlet and the actual value of the target area.

[0003] Although the prior art includes a temperature / humidity collection unit and an actuator, its control logic is only based on threshold judgment of a single detection point, without considering the direct impact of air outlet parameters on adjustment effect, which leads to the inability to intervene in time when the air supply parameters are abnormal and the difficulty in preventing local temperature and humidity imbalance; and leads to large fluctuations in environmental parameters, making it difficult to meet the requirements of high cleanliness environments.

[0004] The adjustment accuracy of the traditional device is limited, and it is difficult to achieve fine temperature and humidity control, especially when there is a large temperature difference or humidity difference between the air outlet and the set area, the adjustment effect is not ideal; it usually does not have intelligent judgment function, and cannot automatically adjust the opening and closing of the air outlet or start the temperature and humidity adjusting device according to the temperature and humidity demand of the set area, leading to increased energy consumption and low adjustment efficiency.
