[0003] The above control method is simple and easy to implement, but since the temperature and humidity of the external environment change in real time, when the temperature sensor and humidity sensor in the clean room sense that the temperature and humidity change in the clean room exceeds the preset value, the air conditioning coil will work and the clean The temperature and humidity of the room are adjusted to the appropriate temperature and humidity. The entire adjustment process needs to start when the temperature of the clean room changes beyond a certain level. Therefore, small fluctuations in the humidity of the clean room cannot be avoided, and there is a certain hysteresis, so it is difficult to adapt to the growing environment. Strict clean room standards

The invention discloses a clean room temperature and humidity control system. The clean room temperature and humidity control system comprises a room body; a first temperature sensor and a first humidity sensor are arranged in the room body; the room body is communicated with an air inlet pipe and an exhaust pipe; an air filter, a humidifier and an air conditioner coil pipe are arranged on the airinlet pipe; a fan is arranged on the air inlet pipe and / or the exhaust pipe; a second temperature sensor and a second humidity sensor are arranged on the air inlet pipe; both the second temperature sensor and the second humidity sensor are arranged at the upstreams of the humidifier and the air conditioner coil pipe; the first temperature sensor, the first humidity sensor, the second temperaturesensor, the second humidity sensor, the fan and the humidifier are all electrically connected with a microcomputer. According to the clean room temperature and humidity control system provided by theinvention, a temperature and humidity regulating and controlling process does not delays, and the fluctuation of the temperature in the clean room is extremely small.
Description
technical field [0001] The invention relates to the technical field of clean rooms, in particular to a clean room temperature humidity control system. Background technique [0002] With the promotion of miniaturization, integration and precision in the fields of electronic information and other fields, the standards of clean rooms are becoming more and more stringent. At this stage, most clean room systems convert the temperature and humidity in the clean room into electrical signals and transmit them to the lower computer through temperature sensors and humidity sensors. The lower computer controls the work of the air conditioning coil and regulates the temperature and humidity of the air. [0003] The above control method is simple and easy to implement, but since the temperature and humidity of the external environment change in real time, when the temperature sensor and humidity sensor in the clean room sense that the temperature and humidity change in the clean room exc...
