S10: and acquiring a remote air supply temperature T1, comparing the remote air supply temperature T1 with a preset air supply temperature Tset, and judging whether the machine room has a refrigeration requirement.
Machine room facilities such as storage data center often adopt air conditioning system to refrigerate and dehumidify the computer lab, and one side or the relative both sides range of computer lab have a plurality of cabinets, install many data storage ware in the cabinet, and a plurality of data storage ware during operation produce a large amount of heats, and one side of cabinet is equipped with cold passageway, and air conditioning system carries cold wind in order to cool down the cabinet to the cabinet through cold passageway.
For example, the remote supply air temperature T1 is a temperature near the cabinet, and the preset supply air temperature Tset is a supply air temperature preset in a controller, which may be integrated with the air conditioner or provided independently.
Optionally, a temperature detection sensor is disposed on the cabinet to obtain the remote supply air temperature T1, and a preset supply air temperature Tset is disposed in the controller, where the preset supply air temperature Tset is, for example, 20 degrees, 25 degrees, and the like, which is not limited in this application.
The remote supply air temperature T1 is the average value T11 and/or the maximum deviation value T12 of the temperature values measured by the temperature detection sensors. For example, the remote supply air temperature T1 may be an average value T11 of a plurality of temperature values measured by one temperature detecting sensor, or it may be only a single temperature value T11 measured by one temperature detecting sensor. Similarly, the remote supply air temperature T1 may be an average value T12 of a plurality of temperature values measured by one temperature detecting sensor with respect to the deviation value of the preset supply air temperature Tset, or it may be only a deviation value T12 of a single temperature value measured by one temperature detecting sensor with respect to the preset supply air temperature Tset.
Optionally, the remote supply air temperature T1 is an average value T11 of a plurality of temperature values detected by the temperature detection sensors on the plurality of cabinets, and is compared with the preset supply air temperature Tset to determine the cooling demand of the machine room.
Optionally, the remote supply air temperature T1 is a maximum deviation value T12 of a plurality of temperature values detected by temperature detection sensors on a plurality of cabinets, so that whether a local hot spot exists in the machine room can be detected, and the local hot spot in the machine room can be automatically eliminated by increasing the rotation speed of the air conditioner fan.
The deviation value is an absolute value of a difference between the temperature value detected by the temperature detection sensor and the preset blowing temperature Tset, and then the maximum value of the deviation values can be taken as the maximum deviation value T12.
In this embodiment, the controller is further provided with a preset temperature deviation threshold Ts in addition to the preset blowing temperature Tset, for example, the preset temperature deviation threshold Ts is 3 degrees, 4 degrees or 5 degrees, and the application does not limit this. For example, the preset temperature deviation threshold Ts is 5 degrees, and when the maximum deviation value of the remote supply air temperature T1 is greater than the preset temperature deviation threshold Ts, it may be determined that a local hot spot exists near the temperature detection sensor, and thus there is a cooling demand for eliminating the local hot spot.
Optionally, the remote supply air temperature T1 may further include the two numerical indicators, i.e., the average value T11 and the maximum deviation value T12, so that the overall refrigeration requirement of the machine room may be considered and the local hot spot may be eliminated.

That is, the average value T11 is greater than the preset blowing temperature Tset, or the maximum deviation value T12 is greater than the preset temperature deviation threshold Ts, the controller can determine that the machine room has a cooling demand, and then step S11 is executed.
When the remote air supply temperature T1 is less than or equal to the preset air supply temperature Tset, which indicates that the temperature in the machine room is good and the machine room does not need to be cooled, step S12 is executed.

S110: and acquiring the air pressure Pr of the cold air channel, and judging whether the air pressure Pr of the cold air channel is within a preset air pressure threshold range.
The refrigerating capacity required by the machine room under normal conditions is within a specific range, and when the air conditioning refrigerating capacity exceeds the range, namely the refrigerating requirement of the machine room is exceeded, the energy consumption of an air conditioner is too high, so that energy waste is caused, and the energy saving is not facilitated; when the air conditioning refrigeration capacity is smaller than the range, the air conditioning refrigeration capacity cannot meet the refrigeration requirement of a machine room and is not beneficial to cooling equipment such as a cabinet and the like; when the air conditioning refrigeration capacity is in the range, the refrigeration requirement of the machine room can be met, and excessive waste of energy can be avoided.
Through the wind pressure that detects cold passageway, and then the detectable amount of wind that records through cold passageway, the refrigeration capacity that the air conditioner passes through cold passageway promptly. And if the air leaks from the machine room, the air pressure of the cold channel is correspondingly reduced. When guaranteeing cold passageway air supply wind pressure Pr and predetermine the wind pressure threshold value within range, explain the amount of wind through equipment that generate heat such as rack, server in a suitable within range, and then avoid leading to the amount of wind through equipment such as partial server, rack not enough because the problem that the computer lab leaks out, and cause the problem that the refrigeration demand of computer lab is not satisfied to take place.

Judging whether the air pressure Pr of the air supplied by the cold channel is within a preset air pressure threshold range, if so, executing the step S111; if the air pressure Pr of the cold channel exceeds the preset air pressure threshold range, executing the step S112; and if the air pressure Pr of the cold channel is smaller than the preset air pressure threshold range, executing the step S113.

The rotating speed of the air conditioner fan is kept unchanged, the air supply pressure of the cold channel is basically kept unchanged, the refrigerating air quantity conveyed to heating equipment such as a server and a cabinet through the cold channel is basically constant, and the refrigerating requirement of a machine room is guaranteed.
S112: and the rotating speed of the air conditioner fan is reduced.
And the rotating speed of the air conditioner fan is reduced, so that the air supply pressure of the cold channel is reduced, and the refrigerating air quantity conveyed to heating equipment such as a server, a cabinet and the like through the cold channel is reduced.
When the refrigerating air quantity conveyed to heating equipment such as a server and a cabinet through a cold air duct is too much, the rotating speed of an air conditioner fan is reduced on the premise of meeting the refrigerating requirement of a machine room, and energy can be saved.
S113: and increasing the rotating speed of the air conditioner fan.
And the rotating speed of the air conditioner fan is increased, so that the air supply pressure of the cold channel is increased, and the refrigerating air quantity conveyed to heating equipment such as a server, a cabinet and the like through the cold channel is increased.
When the machine room leaks wind or other factors cause the refrigeration requirement of the machine room to be not met, the rotating speed of the air conditioner fan is increased, and the refrigeration air quantity conveyed to the heating equipment is increased to meet the refrigeration requirement of the machine room.
S12: and acquiring remote air supply humidity RH1, and comparing the remote air supply humidity RH1 with preset air supply humidity RHSet to judge whether the machine room has a dehumidification requirement.

And a preset air supply humidity Rhset is set in the controller, and the preset air supply humidity Rhset is 0.25, 0.3 or 0.35, for example, and the application does not limit the preset air supply humidity Rhset.
The remote supply air humidity RH1 is the average RH11 and/or the maximum deviation RH12 of the humidity values measured by the humidity detection sensors. For example, the remote supply air humidity RH1 may be the average RH11 of a plurality of humidity values measured by one humidity sensor, or it may be only a single humidity value RH11 measured by one humidity sensor. Similarly, the remote supply air humidity RH1 may be an average RH12 of a plurality of humidity values measured by one temperature sensor relative to a deviation value of the preset supply air humidity RHset, or may be only a deviation RH12 of a single humidity value measured by one humidity sensor relative to the preset supply air humidity RHset.
Optionally, the remote supply air humidity RH1 is an average RH11 of a plurality of humidity values detected by humidity detection sensors on a plurality of cabinets, and is compared with a preset supply air humidity Rhset to determine a dehumidification requirement of the machine room.
Optionally, long-range air supply humidity RH1 is the biggest deviation value RH12 of a plurality of humidity numerical values that humidity detection sensor detected on a plurality of cabinets, and then whether there is the condition of leak source in the detectable computer lab to the influence of the leak source to humidity in the computer lab is reduced to the dehumidification rotational speed through setting up air conditioner fan.
In this embodiment, the controller is provided with a preset humidity deviation threshold RHs in addition to the preset blowing humidity Rhset, for example, the preset humidity deviation threshold RHs is 0.05, 0.10 or 0.15, and the application is not limited thereto. For example, the preset humidity deviation threshold RHs is 0.1, and when the maximum deviation value RH12 is greater than the preset humidity deviation threshold RHs, it may be considered that a leak point exists near the humidity detection sensor, and then, in order to reduce the influence of the leak point on the humidity in the machine room, the dehumidifying requirement of the machine room is obtained.
Optionally, the remote supply air humidity RH1 may further include the two numerical indicators, that is, the average value RH11 and the maximum deviation value RH12, so that the overall dehumidification requirement of the machine room can be considered and the influence of the leakage point on the humidity in the machine room can be eliminated.
When the remote air supply humidity RH1 is greater than the preset air supply humidity RHset, it indicates that the humidity near the equipment such as the cabinet and the server is too high, which is likely to cause a working failure of the equipment such as the data memory or the data processor, and the controller may determine that the machine room has a dehumidification demand, and then execute step S13.
That is, the average value RH11 is greater than the preset blowing humidity RHset, or the maximum deviation value RH12 is greater than the preset humidity deviation threshold RHs, the controller can determine that the machine room has a dehumidification requirement, and then execute step S13.
Otherwise, the machine room has no dehumidification requirement, and step S12 is executed.

The maximum temperature T2 of the far end of the cold channel is further obtained, and the maximum temperature T2 of the far end of the cold channel is compared with the preset maximum temperature Tmax, so that the normal heating of the equipment in the monitoring blind area can be found in time, and further whether the machine room has a refrigeration demand can be judged more accurately.
