Whether the water cooling system is loaded or unloaded depends on the water cooling data obtained in step 110. Further, the number of sets of water cooling units loaded or unloaded in the water cooling system also depends on the water cooling data.

Here, the number of load shedding units is the number of water cooling units that need to be shed from the water cooling system. There are various methods for determining the number of load shedding sets according to the water cooling load rate, for example, a difference between a preset load rate and the water cooling load rate may be calculated, one set of water cooling set is shed if each difference is 5%, and then the number of load shedding sets is determined, a table of the number of load shedding sets corresponding to the water cooling load rate may be preset, and the number of load shedding sets is determined by looking up the table, which is not specifically limited in the embodiment of the present invention.

Specifically, after the chilled water supply temperature and the chilled water pump frequency are determined to meet the loading condition of the water cooling system, the number of loading units is determined according to the chilled water supply temperature and the chilled water pump frequency. Here, the number of the loading units is the number of the water cooling units to be loaded in the water cooling system. There are various methods for determining the number of the loading units according to the chilled water supply temperature and the chilled water pump frequency, for example, a difference between the chilled water supply temperature and a preset temperature and a difference between the chilled water pump frequency and the preset frequency may be calculated, a set of refrigeration units may be loaded at each difference of 2 ℃ and each difference of 5Hz, a table of the number of the loading units corresponding to the chilled water supply temperature and the chilled water pump frequency may be preset, and the number of the loading units may be determined by looking up the table.

and 150, acquiring the outdoor wet bulb temperature.

The outdoor wet bulb temperature refers to the lowest temperature that can be reached in an outdoor environment by merely evaporating moisture. In the operation mode, the refrigeration mode means that the water cooling system is completely cooled by the compressor to circulate chilled water; the all natural cooling mode means that the water cooling system completely cools and circulates chilled water through a cooling tower or a heat exchanger without compressor power consumption; the partial natural cooling mode means that the water cooling system cools the circulating chilled water through a cooling tower or a heat exchanger and achieves the required cold quantity through the refrigeration relay of a compressor, namely, the natural cooling and the compressor cooling are operated simultaneously.
After the outdoor wet bulb temperature is obtained, there are various methods for determining the operation state of the water cooling system according to the outdoor wet bulb temperature, for example, a comparison table of the difference between the return water temperature of the chilled water and the outdoor wet bulb temperature and the operation state of the water cooling system is preset, after the outdoor wet bulb temperature is obtained, the difference between the return water temperature of the chilled water and the outdoor wet bulb temperature is obtained, and the corresponding operation state is obtained through table lookup and is switched; for example, a comparison table of the outdoor wet bulb temperature and the operation state of the water cooling system is preset, and after the outdoor wet bulb temperature is obtained, the corresponding operation state is obtained through table lookup and is switched.
The control method provided by the embodiment of the invention can switch the running state of the water cooling system according to the outdoor wet bulb temperature, can utilize a natural cold source to the maximum extent, and can reduce the running energy consumption of the water cooling system.
Based on any of the above embodiments, step 160 specifically includes: if the temperature of the outer wet bulb of the inner chamber is greater than the first preset temperature within the fifth preset time, switching the operation mode of the water cooling system to a refrigeration mode; if the temperature of the outer wet bulb of the inner chamber is less than or equal to the first preset temperature and greater than the second preset temperature within the fifth preset time, switching the operation mode of the water cooling system to a partial natural cooling mode; if the temperature of the outer wet bulb of the inner chamber is less than or equal to the second preset temperature within the fifth preset time, switching the operation mode of the water cooling system to a full natural cooling mode; wherein the first preset temperature is higher than the second preset temperature.
Specifically, the fifth preset time is preset monitoring time of the outdoor wet bulb temperature for judging whether the water cooling system needs to switch the operation mode. The first preset temperature and the second preset temperature are preset outdoor wet bulb temperature thresholds, the first preset temperature is greater than the second preset temperature, and the combination of the first preset temperature and the second preset temperature can form three temperature intervals, namely, the temperature interval is greater than the first preset temperature, between the first preset temperature and the second preset temperature, and is less than the second preset temperature.
After the outdoor wet bulb temperature is obtained, comparing the outdoor wet bulb temperature with a first preset temperature and a second preset temperature, if the outdoor wet bulb temperature is greater than the first preset temperature in a fifth preset time, determining that the current outdoor wet bulb temperature does not have a natural cooling condition, and switching the operation mode of the water cooling system to a refrigeration mode; if the temperature of the indoor and outdoor wet bulb is between the first preset temperature and the second preset temperature within the fifth preset time, confirming that the current outdoor wet bulb temperature has a partial natural cooling condition, and switching the operation mode of the water cooling system to a partial natural cooling mode; and if the temperature of the indoor and outdoor wet bulb is less than or equal to the second preset temperature within the fifth preset time, determining that the current outdoor wet bulb temperature has all natural cooling conditions, and switching the operation mode of the water cooling system to all natural cooling modes.

If the water cooling load rate η is continuously less than 80% within 15 minutes, it is determined that the water cooling units operating in the current water cooling system have excess power, and the water cooling system can be deloaded to achieve the purpose of saving energy while meeting the water cooling requirement of the data center.
And when the number of the deloading machine sets is 2, after one water chilling unit in the deloading water chilling system is deloaded, waiting for 5 minutes, and then deloading the other water chilling unit in the water chilling system.
If the supply temperature of the chilled water is continuously higher than 15 ℃ within 30 minutes and the frequency of a chilled water pump is continuously higher than 45Hz, the water cooling unit running in the current water cooling system is determined to be overloaded, which is not enough to meet the water cooling requirement of a data center, and the water cooling system needs to be loaded, so that the problem that the service life of equipment is influenced due to equipment abrasion caused by overload of the water cooling unit running in the current water cooling system is solved. At this time, the number of loading sets can be obtained by the following table:
and when the number of the load shedding machine sets is 3, after one set of water cooling machine set is loaded in the water cooling system, waiting for 15 minutes, and then loading the other set of water cooling machine set in the water cooling system.

The number of the deloading units is determined according to the water-cooling load rate, so that the unreliability of artificial judgment is avoided, the water-cooling system is deloaded gradually, the instability of the water-cooling system caused by the steep rise of the power of the water-cooling units running in the water-cooling system due to the simultaneous deloading of a plurality of water-cooling units is avoided, the service life of the water-cooling units is influenced, the running energy consumption of the water-cooling system is effectively reduced, and the running cost is reduced.
