Problems solved by technology
The outdoor unit of the air conditioner in the precision computer room is located in an extremely cold area. The accumulation of ice and snow on the fan and the guide ring will easily cause the air volume to attenuate and even the fan to stall, which will cause great hidden dangers to the cooling safety and operation stability of the data room.
At present, there is no specific solution to this problem in the field of precision computer room air conditioners. Therefore, in order to ensure the safety, stability and high precision of precision computer room air conditioners, it is of great significance to design an air conditioner external unit and a control method.

The invention provides an air conditioner outdoor unit and a control method thereof. The control method comprises the following steps of 1, acquiring an ambient temperature; 2, acquiring current operating parameters of the air conditioner outdoor unit when the ambient temperature is less than T0; and 3, controlling a fan module and a heating device module according to the operating parameters of the air conditioner outdoor unit. According to the air conditioner outdoor unit and the control method thereof, by monitoring and collecting the outdoor ambient temperature, system condensation pressure and fan operation state data, the accumulated snow condition of the fan module is judged through control operation logic of a system, ice and snow accumulated on a fan of the outdoor unit can be melted away, and therefore the situations that the air volume of the fan is reduced and the fan is even blocked in extremely cold weather can be effectively prevented, the high control precision and operation stability requirements of an air conditioner in a precise machine room are effectively guaranteed, and the service life of the unit can be prolonged.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner external unit and a control method thereof. Background technique [0002] The power density of data cabinets is increasing rapidly in the context of the 5G era. In view of the particularity of the year-round uninterrupted cooling application scenario, the performance requirements for data room cooling equipment are also getting higher and higher. The outdoor unit of the air conditioner in the precision computer room is located in an extremely cold area. The accumulation of ice and snow on the fan and the guide ring will easily cause the air volume to attenuate and even the fan to stall, which will cause great hidden dangers to the cooling safety and operation stability of the data room. At present, there is no specific solution to this problem in the field of precision computer room air conditioners. Therefore, in order to ensure the safety, stability,...
