Iron 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 friendlyadvantages. As subway passenger trips and more, how to give passengers a comfortable thermal environment satisfactory, becoming the transport sector needs to be considered resolved. This requires careful design of the subway environmental control system in whichtemperature and Engine Water Shaft Position 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.
