Embodiment one: as shown in fig. 1, the data center cooling system based on split evaporative cooling comprises an exhaust fan 2, a cabinet 3, a mixed air static pressure box 7, an air supply air quantity regulating valve 5, an air return air quantity regulating valve 8, a fireproof valve 9 and an air supply pipeline 10. The split evaporative cooling cabinet comprises a wet filtering film section 11 and a blower section 6, wherein the wet filtering film section 11 and the blower section 6 are connected through a blower pipeline 10 and are controlled in a unified and centralized manner.
The wet filtering film section 11 of the split evaporative cooling cabinet is arranged on an outdoor equipment platform 12 of the data center machine room 1, the air feeder section 6 is arranged on an air supply pipeline 10 in the data center machine room 1, and cold air is directly supplied to the split evaporative cooling cabinet 3 for cooling of the data center.
The filtering wet film section 11 of the split evaporative cooling cabinet can automatically switch between a dry working condition (no spraying) or a wet working condition (spraying starting) according to the heat removal amount in the data center and the outdoor climate condition, and simultaneously can adjust the opening of the return air volume adjusting valve 8 to mix partial return air in the air mixing static pressure box 7 so as to prevent the dew condensation of the indoor air supply pipeline 10 and the air outlet 4, so that the air supply temperature is higher than the indoor dew point temperature.
The working principle is as follows:
when the dry working condition (no spray) is running, the following steps are:
when the outdoor environment is lower than a set value (the dry bulb temperature is not higher than 16 ℃ in this example), the exhaust fan 2 and the blower section 6 positioned on the air supply pipeline 10 are started at the same time, outdoor fresh air is filtered by the filtering wet film section 11 of the split evaporative cooling cabinet, directly enters the air mixing static pressure box 7 after passing through the air supply pipeline 10 and the fireproof valve 9, the outdoor air inlet temperature and the dew point temperature of the indoor environment are detected at the moment, if the outdoor air inlet temperature is higher than the dew point temperature of the indoor environment by more than 2 ℃, the return air volume regulating valve 8 is closed, the fresh air supply of the indoor air is completely adopted, and the outdoor fresh air is blown to the split evaporative cooling cabinet 3 through the air outlet 4 under the action of the blower section 6 and is used for cooling the split evaporative cooling cabinet 3. If the outdoor air inlet temperature is lower than the dew point temperature +2deg.C of the indoor environment, the opening of the return air volume regulating valve 8 is regulated according to the air supply temperature PID, so that the air supply temperature is higher than the dew point temperature of the indoor environment by more than 2deg.C, and the air supply pipeline 10 or the air outlet 4 is prevented from dewing.
When wet working condition (spray on) running state:
when the operation is only performed under the dry working condition (without spraying), and all heat cannot be taken away, the wet working condition operation (taking outdoor dry bulb temperature is more than 16 ℃ and the wet bulb temperature is less than or equal to 16 ℃ as an example) is started, at the moment, a spray pump in the filtering wet film section 11 of the split evaporative cooling cabinet is started to heat the wet film, and a water supplementing valve is opened periodically. After the air from the environment is humidified and subjected to isenthalpic temperature reduction under the action of the blower section 6, the air mixing static pressure box 7 is carried out from the air supply pipeline 10, and the return air volume regulating valve 8 is completely closed at the moment to directly supply air.
When the air conditioner is in an operating state (without evaporative cooling):
when the dry working condition and the wet working condition are adopted only and all heat cannot be taken away (the outdoor wet bulb temperature is taken as an example here to be more than 16 ℃), the exhaust fan 1 and the blower section 6 are closed, the air quantity regulating valve 5 is closed and blown at the same time, the original precise air conditioner of the data center is started to refrigerate, and the control system runs by itself according to the setting.
Compared with the existing data center refrigeration technology, the data center cooling system based on split evaporative cooling can fully utilize different outdoor weather conditions, selectively start different cooling modes to meet the air conditioning cooling requirements of a data center machine room, is particularly suitable for the traditional energy-saving reconstruction system of the data center machine room, can make an evaporative cooling split evaporative cooling cabinet into split type, can realize the purpose of controlling indoor air supply temperature, and simultaneously solves the noise problem caused by outdoor arrangement of the split evaporative cooling cabinet. The split type evaporative cooling cabinet is designed in a split type, the natural cold source is fully and efficiently utilized, the energy cost of the air conditioner for cooling of the data center is greatly reduced, meanwhile, the reliability of the system is improved, the application area of the split type heat pipe technology is expanded, and the split type evaporative cooling cabinet is energy-saving, environment-friendly and high in practicability.
