The indoor fan operates according to the set wind speed.
And judging whether the pressure intervention condition is met.
When the rack-type air conditioner is operated to meet the pressure intervention condition, which indicates that the pressure of the whole refrigeration system is higher, the compressor may be in an operation state exceeding the standard pressure condition. If the compressor runs for a long time in such a state, the risk of damage to the compressor is increased, thereby reducing the continuous use time of the rack air conditioner and reducing the product quality.
To avoid this condition, the automatic control room fan is operated at an intervention speed that is less than the set speed when the pressure intervention condition is satisfied.
When the indoor fan operates according to the intervention rotating speed, the heat exchange is also reduced along with the reduction of the wind speed, the operating pressure of the refrigeration cycle of the whole rack-mounted air conditioner is further reduced by , the operating environment of the compressor is automatically adjusted to the standard operating environment, and the compressor is prevented from working under the condition of exceeding the standard pressure.
Step is executed to keep the indoor fan running at the intervention speed and judge whether the quit intervention condition is satisfied.
When the operation of the rack type air conditioner meets the condition of quitting intervention, the pressure of the whole refrigerating system is restored to a normal state, is carried out, the indoor fan is controlled to operate according to the set rotating speed, and the rack type air conditioner is restored to normal operation.

It is determined whether the real-time indoor ambient temperature is equal to or higher than the th set indoor ambient temperature.
It is determined whether the real-time outdoor ambient temperature is equal to or greater than the th set outdoor ambient temperature.
When the real-time indoor environment temperature is greater than or equal to the th set indoor environment temperature and the real-time outdoor environment temperature is greater than or equal to the th set outdoor environment temperature, it is indicated that the current heat load is high, the probability that the compressor operates near the condition of exceeding the standard pressure is high, and in such a state, it is determined that the pressure intervention condition is satisfied.
Preferably, th set indoor ambient temperature and th set outdoor ambient temperature are obtained under experimental conditions, preferably, standard reference temperatures in the same cabinets are set for different models of compressors at experimental time, electric elements or electronic elements in the cabinets of the data center can keep working normally for a long time at the standard reference temperatures, the cabinet air conditioner is operated to maintain the temperature in the cabinets at the standard reference temperatures, in this experimental environment, the working states of the compressors at different indoor ambient temperatures and outdoor ambient temperatures are tested, critical indoor ambient temperatures and critical outdoor ambient temperatures corresponding to the compressors when operating beyond the standard pressure are found, th set indoor ambient temperature and th set outdoor ambient temperature are set according to the critical indoor ambient temperatures and the critical outdoor ambient temperatures, wherein preferably, the th set indoor ambient temperature is set to 90% -95% of the critical indoor ambient temperature, the th set outdoor ambient temperature is set to 90% -95% of the critical outdoor ambient temperature, and specific outdoor ambient values of the critical indoor ambient temperature and the critical ambient temperature are set to th th set as the indoor ambient temperature and the critical ambient temperature are not different models of the compressors.
Similarly, it is also preferable in this embodiment to determine whether the exit intervention condition is satisfied based on the real-time indoor ambient temperature and the real-time ambient temperature. Specifically, the fan operates at the intervention speed in the control room. And continuously sampling the real-time indoor environment temperature and the real-time outdoor environment temperature.
And judging whether the real-time indoor environment temperature is less than or equal to a second set indoor environment temperature or not and whether the real-time outdoor environment temperature is less than or equal to a second set outdoor environment temperature or not. And if the real-time indoor environment temperature is less than or equal to the second set indoor environment temperature and the real-time outdoor environment temperature is less than or equal to the second set outdoor environment temperature, indicating that the pressure of the system is recovered to be stable, and controlling the indoor fan to recover the set wind speed to operate. The second set indoor ambient temperature and the second set outdoor ambient temperature are preferably obtained through experiments, the second set indoor ambient temperature is preferably 70% to 80% of the critical indoor ambient temperature, and the second set outdoor ambient temperature is preferably 70% to 80% of the critical outdoor ambient temperature.
