Subway environmental control systems widely used in temperature and humidity sensor

Metro has become an essential transportation in big cities run the tool , it has a large volume, punctuality is good, fast and safe , transport , high efficiency, environmentally friendly advantages. As subway passenger trips and more, how to give passengers a comfortable thermal environment satisfactory , becoming the transport sector needs to be considered and resolved. This requires careful design of the subway environmental control system in which temperature and humidity sensor detection tool is required . Metro 's large volume, which is a large passenger flow , the required variation in fresh air . Therefore subway air conditioning load changes, to achieve energy must resort to automatic control means. Automatic control system as an integral part of , environmental sensors in the subway more plays an important role . The environmental control system in the subway , the main use of the indoor Camshaft Position Sensor and humidity sensor , duct temperature and humidity sensors . We can order at the station concourse and platform areas and other public areas as well as important equipment room set indoor temperature and humidity sensors to monitor real-time temperature and humidity of the station . These parameters can help operational staff working conditions of various systems of the station to make reasonable adjustments to keep always in the public areas of the station more comfortable environment to ensure that the device has been in the right room temperature under . Indoor temperature and  Car Temperature Sensor  are generally mounted on the station concourse , platform and equipment room on the wall or on top . In the meantime, we can at the station 's new air chamber and the return air duct temperature and humidity chamber mounted sensors to monitor the outdoor air and the temperature and humidity inside the station . Environmental control system according to the data collected by sensors to determine the environmental quality of the station , and according to a variety of conditions pre-designed for automatic switch , automatic control system in order to achieve automatic control of the environment of the station , so that the station is always in a more environment comfortable environment, and ultimately achieve the purpose of energy saving and emission reduction . Pipeline temperature and  Crankshaft Positioning Sensor  is usually installed in the new and the return air plenum chamber walls. Thus, the temperature and humidity sensor usefulness in life more and more, it is not only in the station , greenhouse , file management and food industry has applied , is now in the subway environmental control system has also been adopted .
