1、 Basic Introduction to Constant Temperature and Humidity Laboratory
The temperature and humidity laboratory uses specific specialized equipment and technical methods to ensure that the room temperature and humidity meet specific atmospheric requirements for humidification and testing standards. The constant temperature and humidity laboratory is the infrastructure for product quality inspection, producer management, and product quality inspection in the distribution field. The constant temperature and humidity laboratory is a department responsible for cotton spinning, wool spinning, chemical fiber, papermaking, packaging, tobacco manufacturing, quality inspection, textile inspection, and related ISO and GB standards for textiles, textile raw materials, paper, and paper products. Widely used for qualitative physical items such as cardboard boxes that should be inspected under standard atmospheric conditions. The standard atmosphere for fiber and fiber raw material inspection complies with ISO139 and GB6529 standards, with a temperature of 20 ± 2 ° C and a relative humidity of 65% ± 2%. The standard atmosphere for inspecting paper, paper products, and cardboard boxes complies with ISO187 and GB10739 standards, with a temperature of 23. ± 1 ° C, relative humidity 50% ± 2%. Constant temperature and humidity, except for the constant temperature and humidity laboratory, low temperature 5-18 ° C, high temperature 30-80 ° C, relative humidity less than 40% RH, low humidity, relative humidity exceeding 80% RH, etc.
2、 Basic Introduction to Constant Temperature and Humidity Cleanrooms
A clean room with constant temperature and humidity refers to the removal of particles, harmful air, bacteria, and other pollutants from the air in a specific space, as well as the removal of indoor temperature, cleanliness, indoor pressure, wind speed, and airflow. More and more distribution, noise, vibration, lighting, and static electricity are being controlled within a certain range, and the rooms are specially designed. This means that regardless of how the external air changes, the room can maintain its original cleanliness, temperature, humidity, and pressure requirements. The main function of a clean room is to control the cleanliness, temperature, and humidity of the air that products come into contact with, so that products can be manufactured in a favorable environmental space.
3、 How is a constant temperature and humidity laboratory defined
1. Volatility: Refers to the difference between the actual measured value (PV) and the target set value (SP/SV) of a device or equipment during control operation. The calculation time for this value varies and different standards are set. In environmental testing equipment, calculations begin 15 minutes after reaching the temperature, while in constant temperature and humidity machines (some called constant temperature and humidity air conditioners and precision air conditioners), the larger the value, the lower the control accuracy of the equipment. It will be easier and more accurate. This term is confusing.
2. Uniformity: refers to the difference between the average of 9 standard test points and the highest or lowest point in 3D space. In addition to the control accuracy of the equipment, the system also has an air circulation design. In a constant humidity system, this value is particularly important and also a particularly difficult indicator to achieve. People with many mysterious motives will steal this value and volatile indexes to reduce the overall demand of the system and achieve their goals, which many customers cannot distinguish.
3. Accuracy: Usually used as an indicator for sensors and instruments, as an important parameter to distinguish their functions, but this setting has a certain impact on controlling fluctuations, but the displayed values are 20.0 and 20.00. As long as. However, it is not used as the primary constant indicator for devices and is often confused with volatility indicators.
4. Deviation: refers to the difference between the measured value and the actual value. This value is usually published by third-party calibration units and is mainly used for constant sensor and instrument performance. Many shrewd people have stolen this value and the uniformity index.
4、 The function of a constant temperature and humidity chamber
A room with constant temperature and humidity is used to test the performance of different materials in different environments, and to test the heat resistance, cold resistance, drought resistance, and moisture resistance of different materials.
The constant temperature and humidity chamber built by our company adopts intelligent control mode to achieve the functions of cooling, dehumidification, heating, humidification, etc. of the unit, meeting the needs of customers for precise control of indoor environmental temperature and humidity. All products sold should be tested before leaving the factory. Therefore, establishing a constant temperature and humidity chamber has brought many conveniences and benefits to many companies, and is also useful for manufacturers to improve quality and meet customer needs.
