The fresh air system is an independent air treatment system composed of a supply air system and an exhaust system. Intelligent control device is used for 3~35kV indoor switchgear, suitable for central cabinet, hand car cabinet, fixed cabinet, ring network cabinet and other switchgear. With primary loop simulation diagram and switch status indication, high voltage live display, automatic temperature and humidity control, human body induction automatic lighting, voice prompt, electrical parameter measurement and RS485 communication interface and many other functions, set operation, display in one. High-voltage cabinet electromagnetic locks can not be installed in some places mechanical interlocks, you can use electromagnetic locks to lock The conditions for unlocking are met by wiring. High-voltage live display is a kind of indicative safety device that is directly installed on indoor electrical equipment and visually shows whether the electrical equipment has an operating voltage. When the device has an operating voltage, the display window flashes to warn people that the high-voltage equipment is electrified, and there is no indication when there is no power. The device is generally installed in the incoming busbar, circuit breaker, main transformer, switchgear and other places that need to show whether it is live. It is divided into tubular fresh air system and tubeless fresh air system. The pipeline fresh air system is composed of fresh fans and pipe fittings, which enter the room through outdoor air purification, and indoor air enters through the pipeline; The duct fresh air system is composed of fresh air units, which also enter the room through outdoor air purification. Relatively speaking, the number of pipeline fresh air systems is large, which is more suitable for industrial or large-area office use, while the unpiped fresh air system is easy to install and more convenient for family use.
The fresh air system uses special equipment to send fresh air into the room on one side of the closed room, and then discharge it from the other side, forming a "fresh air flow field" in the room to meet the needs of fresh air exchange.
Finally, the application of a temperature and humidity controller in the air purifier fresh fan system is introduced, the sensor is developed and produced by VIA Group, the price and quality are guaranteed, digital temperature and humidity controller - temperature and humidity module, using polymer resistive humidity sensor and NTC temperature sensor, with high-performance single-chip microcomputer. High cost performance, low power consumption, small size, single-wire serial interface, accurate calibration, digital output, the product has the advantages of ultra-fast response speed and strong anti-interference ability.
