Description
Technical Field

Background
With the development of internet and information technology, data centers are rapidly built, and precision air conditioners are widely applied as indispensable important basic equipment of the data centers. The precision air conditioner is mainly used for adjusting the temperature and the humidity of a data center. The data center is operated by high-value IT equipment such as a server, a storage device and a network, the stable operation of the equipment can be influenced by the humidity besides the temperature, static electricity can be generated due to too low humidity to easily damage electronic components, condensed water can be generated due to too high humidity to possibly damage the electronic components, and therefore the data center precision air conditioner has a humidifying function for meeting the constant humidity requirement. The precise air conditioner has the humidifying function that water is supplied to the humidifier through an external water supply pipeline, and the humidifier generates a large amount of steam to meet the humidity control requirement. The humidifying water supply pipeline of the precision air conditioner is usually directly connected to a tap water pipeline, and if the installation process is not in place or the quality of pipes is in a problem, the phenomena of water leakage and even splashing can be caused, so that immeasurable loss is caused to a data center.
For the problem of water leakage of the air conditioner, the mainstream practice in the industry at present is to adopt the following two schemes, or adopt a mode of combining the two schemes. The first scheme is as follows: install the retaining dam in air conditioner bottom and take precautions against, the retaining dam keeps off water inside not letting the outflow when air conditioner takes place a small amount of when leaking, reduces the influence to peripheral equipment. Scheme II: and a water leakage alarm is additionally arranged, and when water leakage occurs, the water leakage alarm sends out an alarm signal to inform a manager to process. However, the two schemes can not thoroughly solve the hidden trouble caused by water leakage of the precision air conditioner, the scheme of additionally arranging the water blocking dam at the bottom of the precision air conditioner is adopted, only a small amount of water leakage in the air conditioner is prevented, if the water leakage amount greatly exceeds the capacity of the water blocking dam, the water can flow outwards to damage peripheral equipment, the water blocking dam can only prevent the water leakage in the air conditioner, and if the water leakage amount of an external water supply pipeline of the precision air conditioner is prevented. The scheme of additionally installing the water leakage alarm only plays a role in warning and prompting after water leakage occurs, and if managers cannot timely handle large-area damage possibly caused by equipment in a machine room, economic loss cannot be measured.
In conclusion, how to timely find out when water leakage occurs in a water inlet pipeline and a precision air conditioner of a data center, the problem that the loss is reduced to the minimum by cutting off an external water source at the first time is urgently needed to be solved at present.
