Alternatively, if the surface cooler temperature that IBMS systems are collected, which is more than (exceeding), presets surface cooler temperature upper limit
(such as 15 degrees Celsius), and reach 5 minutes or more than after five minutes, surface cooler temperature still persistently rises, then judges pre-cooled air-conditioning box
There is water delivery temperature of freezing water or Traffic Anomaly in system, and produces chilled water and send water fault alarm control signal, cold to trigger
Freeze water and send water fault alarm.
Alternatively, if the primary filter pressure difference that IBMS systems are collected, which is more than (exceeding), presets primary filter pressure difference
Upper limit value (it is to be appreciated that default primary filter pressure difference upper limit value can be determined according to explanation of dispatching from the factory), then judge precooling air-conditioning
There is failure or needs to be cleaned or replaced in case primary filter, and produces primary filter fault alarm control letter
