Computer room air conditioning water warning linkage shutdown processing method

by:KEBO      2020-05-13
Computer room air conditioning long running will appear abnormal refrigerant pressure, cause the clogging in evaporator is icy, drainage pipeline, especially in the rainy season, the humidity increases, easy to produce a large number of condensed water drop on the ground. Appear this kind of situation, if cannot be handled in a timely manner, will affect the operation of the equipment, in addition, the ground water endangers other devices, cause potential safety hazard. At present, the rooms are all unattended, the air conditioning is leaking monitoring on power environmental monitoring systems all water immersion probe. When there is leaking, water immersion probe even collected the failure, can only be uploaded to the network management system through the work order form or IVR telephone inform maintenance personnel, cannot turn off air conditioning in the first time, will continue to leak before maintenance staff rushed to the scene. Aiming at this problem, suzhou move by improving the current air conditioning water collection technology, prone to leakage in the air conditioning machine ( Such as evaporator tray, drains, etc. ) Adding water probe, expanding the scope of the collection and early warning, in the air conditioning power front-end, setting up a communication controller, two intermediate relay contact and spring reset switch, composed of the secondary control circuit, and implement and monitor acquisition board to cable unicom, database backend directives in the monitoring system software set in the linkage control of intermediate relay portion in the auxiliary contact and instruction, and the monitoring system of power supply and signal of double unicom. When the computer room air conditioning were under water warning automatically & other; Body & throughout; Shutdown, reduced the drops of water to a minimum, for maintenance personnel rushed to the scene to deal with for more time. So far, the plan has been in suzhou moving parts room to pilot installation, and after repeated verification, the success rate reached 100%. The successful practice of this project, making the original ring early warning system for the monitoring system of air conditioning water more intelligent, automation, greatly reduces the leakage fault's sphere of influence and harmfulness.
