室外换热器的换热盘管的中部设有第一温度感应器，该温度感应器能测量室外换热器的盘管中部温度，即冷凝温度。室外机上还设有检测室外环境温度的第二温度感应器。上述的两个温度感应器均与空调主控制器电连接。室外机还设有上、下两个换热的风机，两个风机也与空调的主控制器电连接。两个风机在空调主控制器控制下，可以以五个风档运行，即高风档、中风档、低风档、超低风档和停风档。高风档指两个风机均高风档运行，中风档指两个风机均中风档运行，低风档指两个风机均低风档运行，超低风档指一个风机低风档运行而另一个风机停机，停风档指两个风机均停机。A first temperature sensor is provided in the middle of the heat exchange coil of the outdoor heat exchanger, and the temperature sensor can measure the temperature in the middle of the coil of the outdoor heat exchanger, that is, the condensation temperature.

变频压缩机的运行频率随着室外环境温度的高低和室内机制冷量的需求的大小（即室内机开机的台数）不断变化，而室外换热器的换热面积是不变的，其换热量取决于风机运行的风档，如果风机运行的风档与空调的压缩机运行频率不匹配，如风档过高，则噪音大、风机能耗大，而且盘管中部压力过低、冷凝温度低，不能正常制冷，而风档过低，则盘管中部压力大、冷凝温度高，容易出现高压故障，同样无法正常制冷。The operating frequency of the inverter compressor changes continuously with the outdoor ambient temperature and the cooling capacity demand of the indoor unit (that is, the number of indoor units powered on), while the heat exchange area of the outdoor heat exchanger is constant, and its heat exchange The volume depends on the wind gear of the fan. If the wind gear of the fan does not match the operating frequency of the compressor of the air conditioner. If the windshield is too low, the pressure in the middle of the coil will be high, the condensation temperature will be high, and high pressure faults will easily occur, and normal cooling will also not be possible.

f、室外风机启动过程完成后，实时监测第一温度感应器的冷凝温度，并即时调整室外风机运行的风档，如果此刻的冷凝温度≤42℃，则降低一个风档运行室外风机，如果此刻的冷凝温度＞42℃且≤49℃，则保持原风档运行室外风机，如果此刻的冷凝温度＞49℃且＜52℃，则提高一个风档运行室外风机，如果此刻的冷凝温度≥52℃，则直接高风档运行室外风机；f. After the start-up process of the outdoor fan is completed, monitor the condensation temperature of the first temperature sensor in real time, and adjust the wind speed of the outdoor fan immediately. If the condensation temperature at the moment is ≤ 42°C, reduce a wind speed to run the outdoor fan. If the condensing temperature is > 42°C and ≤ 49°C, keep the original wind gear to run the outdoor fan. If the current condensing temperature is > 49°C and < 52°C, then increase a wind speed to run the outdoor fan. If the current condensing temperature is ≥ 52°C , then run the outdoor fan directly at high wind speed;
g、风机启动过程完成后，实时监测第一温度感应器的冷凝温度，并即时调整室外风机运行的风档，如果此刻的冷凝温度≤30℃，则停止运行室外风机，直到冷凝温度上升到40℃，再以低风档运行室外风机，如果此刻的冷凝温度＞30℃且≤42℃，则降低一个风档运行风机，如果此刻的冷凝温度＞42℃且≤49℃，则保持原风档运行风机，如果此刻的冷凝温度＞49℃且＜52℃，则提高一个风档运行风机，如果此刻的冷凝温度≥52℃，则直接高风档运行风机。g.

该控制方法的原理为：多联式空调机组制冷运行时，冷凝温度能反应出室外机盘管中部压力的大小，如果加强室外风机运行的风档，则换热量增大，气体冷凝的量增多，冷凝温度和盘管中部压力会降低；而降低室外风机运行的风档，则换热量减少，气体冷凝的量减少，盘管中部的压力及冷凝温度会提高；而室外环境温度越高，空调的换热效果越差，室外风机运行的风档要求越高；而运行的室内机的台数越多，压缩机的运行频率和工作负荷越大，室外风机的运行的风档要求也越高，故能根据冷凝温度、室外环境温度、开机的室内机台数，综合合理调节室外风机的运行风档。The principle of this control method is: when the multi-connected air conditioner unit is in cooling operation, the condensation temperature can reflect the pressure in the middle of the outdoor unit coil. If the temperature increases, the condensing temperature and the pressure in the middle of the coil will decrease; if the windshield of the outdoor fan is lowered, the heat exchange will decrease, the amount of gas condensation will decrease, and the pressure in the middle of the coil and the condensing temperature will increase; and the higher the outdoor ambient temperature , the worse the heat transfer effect of the air conditioner, the higher the wind gear requirement for the outdoor fan; the more indoor units are running, the greater the operating frequency and workload of the compressor, and the higher the wind gear requirement for the outdoor fan. High, so the operating wind gear of the outdoor fan can be comprehensively and reasonably adjusted according to the condensing temperature, outdoor ambient temperature, and the number of indoor units that are turned on.
采用以上方法，本发明变频多联式空调机组制冷时室外风机的控制方法与现有技术相比，具有以下优点：By adopting the above method, compared with the prior art, the method for controlling the outdoor fan of the frequency conversion multi-connected air conditioner unit in the present invention has the following advantages:

Avoid the high pressure in the middle of the coil caused by the low windshield and the occurrence of high pressure faults, and ensure normal cooling.
