what temperature should a clean room be

Dust-free room temperature and humidity refer to the requirements for controlling indoor temperature and humidity within a certain range to maintain the quality and effect of objects in the dust-free room. With the advancement of science and technology and the continuous expansion of application fields, dust-free rooms have been widely used in Electronics, Semiconductors, medical, optics and other industries. In order to ensure the normal operation and efficient work of the dust-free room, a set of strict temperature and humidity standards need to be formulated to achieve the requirements of the dust-free environment.

The temperature standard of the dust-free room should be determined according to the specific use and process requirements of the room. Generally speaking, the temperature of the dust-free room should be maintained between 20℃±2℃ to prevent high temperature from damaging equipment and materials. For some special industries such as chip production and biological experiments, the temperature requirements may be more stringent and precise. In this case, the temperature can be controlled within 0.1℃.

The humidity standard of the dust-free room is also very important. Humidity refers to the amount of moisture contained in the indoor air, which directly affects the quality and effect of indoor objects. Excessive humidity can cause corrosion and mildew of equipment and materials, while too low humidity can have an adverse effect on human health. Generally speaking, the humidity of the dust-free room should be maintained between 40%RH±5%RH. For some industries with higher humidity requirements, such as optical manufacturing and precision instruments, the humidity control range can be more stringent.

The temperature and humidity standards of the clean room also need to take into account the comfort and work efficiency of the indoor personnel. An overly humid or dry environment will cause human discomfort and affect work efficiency. Reasonable temperature and humidity standards should take into account the comfort of personnel while meeting the dust-free requirements. Generally speaking, the human body has a strong adaptability to room temperature and humidity. The temperature should be maintained between 22℃ and 26℃, and the humidity should be maintained between 40%RH and 70%RH.

The formulation of dust-free room temperature and humidity standards needs to be continuously adjusted and improved in practice. According to different industry and process requirements, corresponding technical means and control measures should be taken, such as strengthening the updating and maintenance of Air conditioning systems, humidity sensors and humidity control equipment. Strengthen temperature and humidity monitoring and recording, and perform regular calibration and adjustment to ensure that the temperature and humidity of the clean room are controllable and stable.

The formulation of dust-free room temperature and humidity standards is one of the key factors to ensure the normal operation of the modular clean room environment and production quality. Reasonable temperature and humidity standards can ensure the health of equipment and materials, improve work efficiency, and also ensure the comfort of personnel in the working environment. When formulating temperature and humidity standards, they should be evaluated and adjusted according to specific industry and process requirements, and the temperature and humidity control technology of clean rooms should be continuously improved and optimized.
