On the one hand, the air flow rate is reduced and the outlet air temperature is increased. However, after switching from a high-speed gear to a medium-speed gear, the air volume will change greatly. Due to the reduction of the air volume, the heat exchange between the refrigerant flowing in the indoor heat exchanger and the surrounding air will decrease, and the compressor will If the operation remains unchanged, on the other hand, it will cause the temperature of the refrigerant in the indoor heat exchanger to rise, and the air conditioner will resume normal operation. After returning to normal operation, the air conditioner will automatically control the indoor fan to switch from the medium speed gear to the high speed gear. Repeated jumps at the critical point will increase the overall noise of the air conditioner indoor unit. Users will also feel that the air supply is sometimes large and sometimes small, which affects the user's actual experience.

针对现有技术中空调防冷风功能室内风机会在档位临界点反复跃变，增加空调室内机的整机噪音，影响用户的实际体验的问题，设计并提供一种空气调节设备的控制方法。如图1所示，控制方法包括以下多个步骤。Aiming at the problem in the prior art that the indoor fan with anti-cold wind function of the air conditioner will jump repeatedly at the critical point of the stall, which will increase the overall noise of the indoor unit of the air conditioner and affect the actual experience of the user, a control method for air conditioning equipment is designed and provided. As shown in Fig. 1, the control method includes the following steps.
S11，采样室内换热器制冷剂管路实时温度。S11, sampling the real-time temperature of the refrigerant pipeline of the indoor heat exchanger.
空气调节装置优选为分体式一拖一空气调节设备，其控制***以微控制器为核心，微控制器的输入端连接温度传感器。温度传感器设置在室内换热器上或者室内换热器附近以采样室内换热器制冷剂管路实时温度。开机状态下，微控制器采样室内换热器制冷剂管路实时温度。The air-conditioning device is preferably split-type one-drag-one air-conditioning equipment, and its control system uses a microcontroller as the core, and the input end of the microcontroller is connected to a temperature sensor. The temperature sensor is arranged on or near the indoor heat exchanger to sample the real-time temperature of the refrigerant pipeline of the indoor heat exchanger. In the power-on state, the microcontroller samples the real-time temperature of the refrigerant pipeline of the indoor heat exchanger.
S12，判定管路实时温度是否满足保护条件。S12, determining whether the real-time temperature of the pipeline satisfies the protection condition.
如果不满足保护条件，则保持室内风机不开机，防止送风温度过低。If the protection conditions are not met, keep the indoor fan off to prevent the temperature of the air supply from being too low.
S13，如果满足保护条件，控制室内风机按照第一设定转速运行，同时开始执行优选的防冷风控制过程。S13, if the protection condition is satisfied, the indoor fan is controlled to run at the first set speed, and at the same time, the optimal anti-cold wind control process is started.
S14，开始计时至第一有效计时周期结束。S14, start timing until the end of the first effective timing period.
S15，判定第一有效计时周期结束时的管路实时温度是否满足预判条件。S15, determining whether the real-time temperature of the pipeline at the end of the first effective timing period satisfies the pre-judgment condition.
S16，如果满足预判条件，即说明管路实时温度下降且位于临界值附近，此时不对室内风机送风进行强制干预，避免出现室内风机送风反复跃变，同时设定第一有效周期结束时的管路实时温度为第一有效温度。S16. If the pre-judgment condition is met, it means that the real-time temperature of the pipeline has dropped and is near the critical value. At this time, no mandatory intervention is performed on the air supply of the indoor fan to avoid repeated jumps in the air supply of the indoor fan. At the same time, the end of the first effective period is set. The real-time temperature of the pipeline at that time is the first effective temperature.
S17，开始计时至第二有效计时周期结束。S17, start timing until the end of the second effective timing period.
S18，设定第二有效计时周期结束时的管路实时温度为第二有效温度。S18, setting the real-time temperature of the pipeline at the end of the second effective timing period as the second effective temperature.

S20，判定有效温差是否满足干预条件。S20, determining whether the effective temperature difference satisfies the intervention condition.
S21，如果有效温差满足干预条件，则说明管路实时温度在连续的第一有效计时周期和第二有效计时周期中遵循大致相同的下降趋势，在这种条件下管路实时温度发生反复跃变的可能性小，即控制室内风机按照第二设定转速运行，对室内风机的送风量进行干预，避免大量冷风送入室内环境中。同时清除第一有效温度和第二有效温度，并将第二有效周期结束时的管路实时温度记为第一有效温度。S21, if the effective temperature difference satisfies the intervention condition, it means that the real-time temperature of the pipeline follows roughly the same downward trend in the continuous first effective timing period and the second effective timing period. Under this condition, the real-time temperature of the pipeline undergoes repeated jumps The possibility is small, that is, the indoor fan is controlled to run at the second set speed, and the air supply volume of the indoor fan is intervened to prevent a large amount of cold air from being sent into the indoor environment. At the same time, the first effective temperature and the second effective temperature are cleared, and the real-time temperature of the pipeline at the end of the second effective period is recorded as the first effective temperature.
通过上述方法，可以在开机初始阶段以及正常运行阶段形成有效的防冷风保护，监测并及时检测管路实时温度下降且位于临界值附近的异常状态，并在发现异常状态之后保持进一步监测，直至判定有效温差满足干预条件，管路实时温度发生反复跃变的可能性小时，控制室内风机按照第二设定转速运行，对室内风机的送风量进行干预，有效避免室内风机转速反复跃变的问题，提高用户体验。Through the above method, an effective anti-cold wind protection can be formed in the initial stage of starting up and in the normal operation stage, and the abnormal state of the real-time temperature drop of the pipeline and near the critical value can be monitored and detected in time, and further monitoring is maintained after the abnormal state is found until the judgment is made. The effective temperature difference meets the intervention conditions, and the possibility of repeated jumps in the real-time temperature of the pipeline is small. The indoor fan is controlled to run at the second set speed, and the air supply volume of the indoor fan is intervened to effectively avoid the problem of repeated jumps in the speed of the indoor fan. , improve user experience.
作为一种可选的方式，判定管路实时温度是否满足保护条件包括以下步骤：判定管路实时温度是否大于基准温度，如果管路实时温度大于基准温度，则管路实时温度满足保护条件。如果管路实时温度小于等于基准温度，则管路实时温度不满足保护条件。基准温度优选设定为38℃。As an optional manner, determining whether the real-time temperature of the pipeline meets the protection condition includes the following steps: determining whether the real-time temperature of the pipeline is greater than the reference temperature, and if the real-time temperature of the pipeline is greater than the reference temperature, the real-time temperature of the pipeline meets the protection condition. If the real-time temperature of the pipeline is less than or equal to the reference temperature, the real-time temperature of the pipeline does not meet the protection condition.

作为一种可选的方式，判定有效温差是否满足干预条件包括以下步骤：判定有效温差的绝对值是否大于等于温差阈值，如果有效温差的绝对值大于等于温差阈值，则有效温差满足干预条件。As an optional manner, determining whether the effective temperature difference meets the intervention condition includes the following steps: determining whether the absolute value of the effective temperature difference is greater than or equal to the temperature difference threshold, and if the absolute value of the effective temperature difference is greater than or equal to the temperature difference threshold, then the effective temperature difference meets the intervention condition.
优选的，第一有效计时周期设定为1-3分钟，第二有效计时周期设定为1-3分钟。第一有效计时周期和第二有效计时周期优选设定为具有相同时长，以准确体现在两段持续的、相同的时间段内，管路实时温度的变化状态和变化程度，以准确的对室内风机的风速进行干预。温差阈值优选设置为1℃。Preferably, the first effective timing period is set to 1-3 minutes, and the second effective timing period is set to 1-3 minutes.

If the intervention condition is satisfied, the speed of the indoor fan is actively intervened again. If the intervention condition is not met, keep the current rotational speed of the indoor fan unchanged, and keep the prediction condition unchanged.
