Preferably, in S10, in the operation process of the single unit machine, the air conditioning device may detect the cabinet information of the single unit machine, and may determine whether the outlet air value in the cabinet is sufficient according to the detected cabinet information, so as to adjust the air environment in the cabinet by adjusting the outlet air value of the single unit machine; it can be understood that, because install structures such as computer controller, arithmetic unit and memory in the single machine rack, for guaranteeing that the single machine can normal use, do not influence the availability factor, so need guarantee that the air circumstance in the single machine is in normal condition, in this embodiment, then realized adjusting the air circumstance in the single machine rack to satisfy the device in the single machine rack and can maintain normal operating, and when adjusting the air circumstance in the single machine rack, with the air circumstance in the normal rack as the foundation.
Further, the sensor includes: temperature sensor, humidity sensor, and CO2A concentration sensor, the cabinet information comprising: temperature value T inside cabinet, humidity value H of cabinet and cabinet CO2A concentration value C; by temperature sensor, humidity sensor and CO2The concentration sensor detects the internal temperature value T of the cabinet, the humidity value H of the cabinet and the CO of the cabinet2And (5) concentration value C is obtained, so that the size of the air outlet value M in the air environment is obtained.
It can be understood that when the temperature in the cabinet is around 20 ℃, the relative humidity of the cabinet is around 50% and the cabinet CO2When the concentration is about 350ppm, the environment in the cabinet is more comfortable, and further, CO in the cabinet2The concentration value varies with the operation of the electrical components, when the user opens the cabinet door of the single machine, if the cabinet CO is2When the concentration value C is higher, the health of a user can be influenced after the user inhales, so that high-concentration CO is effectively avoided by setting the air conditioning device2Harm to the user, therefore CO2The concentration sensor detects CO in the cabinet2After the concentration of the mixture is finished,the single machine is adjusted according to the corresponding requirement, namely, the air exchange treatment is carried out in the cabinet through the air conditioning device so as to reduce the CO in the cabinet2The purpose of the concentration value C, thereby reducing the harm to the user.

Preferably, when the sensor detects the cabinet information, the CO first detects the cabinet information2Concentration sensor to CO in cabinet2Concentration detection, in the cabinet CO2When the concentration value C is at the normal value, further in the cabinet CO2On the basis of the concentration value C, the temperature and the humidity in the cabinet are detected by the temperature sensor and the humidity sensor, so that the air outlet value of the air conditioning device is adjusted again, and the normal operation of structures such as a control device in the single machine is met.
Further, in the detection of CO2When the concentration is high, the cabinet CO needs to be judged2The relationship between the concentration value C and a preset concentration value C'; wherein the preset concentration value C' belongs to [320ppm, 380ppm]The preset concentration value C' can be selected from 320ppm, 330ppm, 340ppm, 350ppm, 360ppm, 370ppm and 380 ppm; if detected cabinet CO2When the concentration value C is in the range, the CO in the cabinet is indicated2If the concentration is normal, the cell machine and the air conditioner do not need to be ventilated, if the concentration is normalCabinet CO2When the concentration value C exceeds 380ppm, the air conditioner needs to be ventilated.
Preferably, in S20, when cabinet CO2When the concentration value C is in a normal range, or after the air exchange treatment is carried out on the cabinet through the single machine and the air conditioning device, the normal cabinet CO is adopted2Concentration value C, cabinet internal temperature value T and cabinet humidity value H can obtain the size of air outlet value M in the air environment, specifically, cabinet internal temperature value T, cabinet humidity value H and cabinet CO2Satisfy between concentration value C and the air-out value M:
M=cos[（C×aπ×|T-T'|×|H-H'|）/10Q]；
wherein M is an air outlet value; t is the current cabinet internal temperature value in unit; t' is a preset temperature value in unit; c is the current cabinet CO2Concentration value, in ppm; h is a cabinet humidity value, and H' is a preset relative humidity value; q is the cabinet load cold quantity in W; a is the air output coefficient, and a =3, in units of W/(ppm × ° c); wherein the preset temperature value T' belongs to [20 ℃, 26℃ ]]Optionally 20 deg.C, 21 deg.C, 22 deg.C, 23 deg.C, 24 deg.C, 25 deg.C, 26 deg.C; the preset relative humidity value H' belongs to [ 40%, 60%]40%, 45%, 50%, 55%, 60% can be selected; the air outlet value M belongs to (-1, 1), and different air outlet quantities of the single machine can be correspondingly adjusted according to different sizes of the air outlet value M; specifically, the preset temperature value T 'and the preset relative humidity value H' may be determined according to the actual requirement of the single machine.
Further, the cold volume Q of rack load satisfies: q = Δ T × k × S;
wherein the unit of delta T load temperature difference is; k is the heat transfer coefficient of the cabinet and has the unit of W/(m)2X ° c); s is the area of the outer side of the cabinet, and the unit is m2(ii) a It should be noted that the factors affecting the load cold amount are various, including some heat transfer factors such as the area outside the cabinet and the top cover, and some heat dissipation factors such as the controller and the driver in the cabinet; since there is uncertainty in the heat dissipation factors such as the controller and the driver in the cabinet, in this embodiment, the heat transfer factor is mainly used in calculating the cooling capacity of the cabinet load and passes through the outside of the cabinetAnd calculating the cold quantity Q of the load of the cabinet according to the area.
Specifically, in the formula: in Q = Δ T × k × S, the load temperature difference Δ T satisfies: Δ T ═ T01-T; wherein, T01The temperature value is the external temperature value of the cabinet and is expressed in units; i.e. Q = (T)01-T) xkxS, and the load cooling capacity Q of the cabinet can be obtained through the inside and outside temperature difference delta T of the cabinet, the heat transfer coefficient k of the cabinet and the outside area S of the cabinet, so that the calculation of the air outlet value M in the cabinet can be further realized; it should be noted that, when calculating the cabinet load cooling capacity Q, firstly, the area and height of the cabinet and the thickness of the cabinet side plate can be calculated, so that the area S outside the cabinet can be obtained, and further the cabinet load cooling capacity Q can be obtained; and when the load cold quantity Q of the cabinet is calculated, the calculation can be carried out according to the actual condition of the cabinet.
