What is the general reason for the surge of the central air conditioning main engine?

Is Trane 500 cold ton CVHE or CVHG? This is a three-stage centrifuge, right? Check the CH530 panel of your equipment to see if there is an alarm display. If there is an alarm, it is recommended to call Trane for maintenance. Trane's centrifuge unit adopts unique patented technology, and the whole unit is in a negative pressure state. Once the shock occurs, there are several situations, 1. Leakage of the device can be observed by checking the exhaust device. There is a report on exhaust in the report column of the panel. He has a daily exhaust minute limit, and if he exceeds it, he will call the police. If this happens, it's a pity that your unit needs to pick up the leak. The approach temperature of the evaporator of the cooler is very high, which is the temperature difference between refrigerant and chilled water. If the temperature difference is too large, it means that the heat transfer effect of your unit is getting worse, and it will also cause suffocation of Trane unit. The approaching temperature can also be seen in the report of the cooler evaporator in the report column. When it reaches 5 degrees Celsius, it needs to be cleaned. 3。 The unit was flooded. From the observation mirror at the filter under the exhaust device, we can see that wet and dry are English abbreviations with corresponding colors, which is easy to see. This situation is the most troublesome. I suggest you find the Trane office in your city to solve this problem.
