Methods include:
S410、按预设操作规则启动第一冷源模块为液冷服务器的冷板制冷，并启动氟冷单元为液冷机柜侧面氟冷背板通氟制冷。S410.

室外当前湿球温度≥20℃时，启用机械制冷氟冷，即启用第二氟冷机构对氟冷背板制冷，第三排风机变频运行，关闭第一氟冷机构；When the current outdoor wet bulb temperature is ≥20°C, the mechanical refrigeration fluorine cooling is enabled, that is, the second fluorine cooling mechanism is enabled to cool the fluorine cooling back plate, the third exhaust fan operates at a variable frequency, and the first fluorine cooling mechanism is turned off;
室外当前湿球温度＜20℃时，启用自然冷源氟冷，即启用第一氟冷机构和第一制冷单元对氟冷背板制冷，采取氟泵+喷淋的模式进行冷却制冷，第二排风机变频运行。When the current outdoor wet bulb temperature is <20°C, the natural cooling source fluorine cooling is enabled, that is, the first fluorine cooling mechanism and the first refrigeration unit are enabled to cool the fluorine cooling back plate, and the fluorine pump + spray mode is used for cooling and refrigeration.

S420、监测实时室外湿球温度和第一冷源模块的实时运行状况。S420: Monitor the real-time outdoor wet bulb temperature and the real-time operating status of the first cold source module.
具体的，湿球温度就是当前环境仅通过蒸发水分所能达到的最低温度，与本实施例中，室外湿球温度采取现有的测量方法，本实施例对具体测量方法不作限定。示例性的，在水银温度计的水银球体包上脱脂纱布，并将脱脂纱布的下端浸入盛水的容器中，脱脂纱布在毛细管作用下经常处于湿润状态，由此制成湿球温度计。将湿球温度计置于室外温度和湿度的流动不饱和空气中，假设开始时脱脂纱布中水分(以下简称水分)的温度与空气的温度相同，但因不饱和空气和水分之间存在湿度差，水分必然要气化，水分向空气主流中扩散，气化所需要的汽化热只能由水分本身温度下降放出显热来供给。水温下降后，与空气间出现温度差，空气即将因这种温度差而产生显热传给水分，但水分温度仍继续下降放出显热，以弥补汽化水分不足的热量，直至空气传给水分的显热等于水分气化所需要的汽化热时，湿球温度计上的温度维持稳定，这种稳定温度即为室外湿球温度。Specifically, the wet bulb temperature is the lowest temperature that the current environment can reach only by evaporating water. In this embodiment, the outdoor wet bulb temperature adopts the existing measurement method. This embodiment does not limit the specific measurement method. For example, the mercury sphere of a mercury thermometer is wrapped with degreasing gauze, and the lower end of the degreasing gauze is immersed in a container containing water. The degreasing gauze is often in a moist state under capillary action, thereby making a wet bulb thermometer. Place the wet bulb thermometer in flowing unsaturated air with outdoor temperature and humidity. It is assumed that the temperature of the moisture (hereinafter referred to as moisture) in the skim gauze is the same as the temperature of the air at the beginning. However, due to the humidity difference between the unsaturated air and the moisture, Moisture must be gasified, and the moisture diffuses into the mainstream of the air. The heat of vaporization required for gasification can only be supplied by the sensible heat released by the temperature drop of the moisture itself. After the water temperature drops, a temperature difference appears between the water and the air. The air will generate sensible heat and transfer it to the water due to this temperature difference. However, the temperature of the water will continue to drop and release sensible heat to make up for the insufficient heat of vaporized water until the air transfers the water to the water. When the sensible heat is equal to the heat of vaporization required for moisture to vaporize, the temperature on the wet bulb thermometer remains stable, and this stable temperature is the outdoor wet bulb temperature.
第一冷源模块的运行状况具体通过监测第一冷却盘管的进出口温度差进行判定，当进出口温度差小于预设阈值时，证明第一冷源模块的制冷异常，第一冷源模块的运行状况异常，进出口温度差大于或等于预设阈值时，第一冷源模块的运行状况正常。The operating status of the first cold source module is specifically determined by monitoring the inlet and outlet temperature difference of the first cooling coil. When the inlet and outlet temperature difference is less than the preset threshold, it is proved that the cooling of the first cold source module is abnormal, and the first cold source module The operating status of the first cold source module is abnormal and the inlet and outlet temperature difference is greater than or equal to the preset threshold, the operating status of the first cold source module is normal.
S430、基于第一冷源模块的运行状况确定是否需要启动第二制冷单元替代第一冷源模块为冷板制冷，并基于实时室外湿球温度确定是否需要切换氟冷单元运行模式。S430. Determine whether the second refrigeration unit needs to be started to replace the first cold source module for cold plate refrigeration based on the operating status of the first cold source module, and determine whether the operating mode of the fluorine cooling unit needs to be switched based on the real-time outdoor wet bulb temperature.
具体的，当第一冷源模块的运行状况异常时，判断为需要启动第二冷源模块中的第二制冷单元；Specifically, when the operating status of the first cold source module is abnormal, it is determined that the second refrigeration unit in the second cold source module needs to be started;
室外当前湿球温度≥20℃时，启用机械制冷氟冷，即启用第二氟冷机构对氟冷背板制冷，第三排风机变频运行，关闭第一氟冷机构；When the current outdoor wet bulb temperature is ≥20°C, the mechanical refrigeration fluorine cooling is enabled, that is, the second fluorine cooling mechanism is enabled to cool the fluorine cooling back plate, the third exhaust fan operates at a variable frequency, and the first fluorine cooling mechanism is turned off;
室外当前湿球温度＜20℃时，启用自然冷源氟冷，即启用第一氟冷机构和第一制冷单元对氟冷背板制冷，采取氟泵+喷淋的模式进行冷却制冷，第二排风机变频运行。When the current outdoor wet bulb temperature is <20°C, the natural cooling source fluorine cooling is enabled, that is, the first fluorine cooling mechanism and the first refrigeration unit are enabled to cool the fluorine cooling back plate, and the fluorine pump + spray mode is used for cooling and refrigeration.
