_mim为这里的频率限制值。其中,Fre_
max为频率限制值中压缩机允许运行的最大频率。Fre
_min为频率限制值中压缩机允许运行的最小频率,可预设设定为20Hz或其他数值,也可根据室内风机转速进行获取。基于此,在已知室内风机转 速和环境温度对应的频率限制值后,可将室内风机转速和频率限制值代入上述公式中,以基于室内风机转速对频率限制值进行修正后的计算结果作为第二频率。

Indicates the above-mentioned frequency correction value. Fre_max and Fre_mim are frequency limit values here. Among them, Fre_max is the maximum frequency allowed by the compressor in the frequency limit value. Fre_min is the minimum frequency that the compressor is allowed to run in the frequency limit value, which can be preset to 20Hz or other values, and can also be obtained according to the speed of the indoor fan. Based on this, after the indoor fan speed and the frequency limit value corresponding to the ambient temperature are known, the indoor fan speed and frequency limit value can be substituted into the above formula, and the calculation result after correcting the frequency limit value based on the indoor fan speed is taken as the first Second frequency.

Specifically, in an embodiment, a maximum frequency allowed to run of the compressor corresponding to the outdoor ambient temperature is determined as the frequency limit value. Different outdoor ambient temperatures correspond to different maximum frequencies. The maximum frequency here increases with the increase of the outdoor ambient temperature. In this embodiment, the temperature range where the outdoor ambient temperature is located is determined, and the frequency corresponding to the determined temperature range is used as the maximum frequency here. For example, when T4>40°C, the above Fre_max can be 50HZ (the specific value can be set according to the air conditioner type and other factors); when T4≤40°C, the above Fre_max can be 40HZ (the specific value can be set according to the air conditioner type, etc. Factor requirement setting), it should be noted that, in other embodiments, 40°C here can also be set as thresholds of other values, such as 35°C, 38°C, and so on. In other embodiments, the maximum frequency here may also be directly calculated from the outdoor ambient temperature.

The initial frequency limit values corresponding to different indoor fan speeds have different values. The larger the indoor fan speed, the larger the initial frequency limit value, and the smaller the indoor fan speed, the smaller the initial frequency limit value. In this embodiment, the initial frequency limit value specifically includes an initial minimum frequency and an initial maximum frequency corresponding to the rotational speed of the indoor fan. Based on this, the initial minimum frequency and the initial maximum frequency can be corrected based on the indoor ambient temperature and the outdoor ambient temperature, respectively, and the corrected minimum frequency and maximum frequency are used as frequency limit values.
具体的,可通过以下公式计算得到频率限制值:Specifically, the frequency limit value can be calculated by the following formula:
Fre_
max=Fre_Warmwindmax+a_Warmwind*(T4-35)+
Fre_max = Fre_Warmwindmax+a_Warmwind*(T4-35)+
b_Warmwind*(T1-27)——(2)b_Warmwind*(T1-27)——(2)
Fre_
min=Fre_Warmwindmin+a_Warmwind*(T4-35)+ b_Warmwind*(T1-27)——(3);
Fre_min = Fre_Warmwindmin+a_Warmwind*(T4-35)+b_Warmwind*(T1-27)——(3);
其中,T1为室内环境温度、T4为室外环境温度、a_Warmwind为室外环境对应的修正系数(是已知的常数)、b_Warmwind为室内环境对应的修正系数(是已知的常数),在本实施例中,a_Warmwind大于b_Warmwind,具体分别为1.2和1.0,在其他实施例中,也可根据实际需求设置为其他数值。Fre_
max为频率限制值中压缩机允许运行的最大频率值,Fre_
min为频率限制值中压缩机允许运行的最小频率值。Fre_Warmwindmin和Fre_Warmwindmax为出风温度大于目标温度时风机当前转速所允许压缩机运行频率的最小值和最大值,在本实施例中,Fre_Warmwindmin和Fre_Warmwindmax分别为20Hz和35Hz,在其他实施例中也可设置为其他数值。
Wherein, T1 is the indoor environment temperature, T4 is the outdoor environment temperature, a_Warmwind is the correction coefficient corresponding to the outdoor environment (a known constant), b_Warmwind is the correction coefficient corresponding to the indoor environment (a known constant), in this embodiment , a_Warmwind is greater than b_Warmwind, specifically 1.2 and 1.0 respectively. In other embodiments, it can also be set to other values according to actual needs. Fre_ max is the maximum frequency value that the compressor is allowed to run in the frequency limit value, and Fre_ min is the minimum frequency value that the compressor is allowed to run in the frequency limit value. Fre_Warmwindmin and Fre_Warmwindmax are the minimum and maximum values of the compressor operating frequency allowed by the current speed of the fan when the outlet air temperature is greater than the target temperature. In this embodiment, Fre_Warmwindmin and Fre_Warmwindmax are 20Hz and 35Hz respectively, and can also be set in other embodiments for other values.
这里得到Fre_
max和Fre_
min后可代入上述的公式(1)中计算得到第二频率。
After Fre_max and Fre_min are obtained here, they can be substituted into the above-mentioned formula (1) to calculate the second frequency.
这里,通过室内外温度确定的频率限制值的基础上,结合室内风机转速进行调整后得到第二频率,可保证空调可靠运行、室内温度舒适的基础上,避免出风温度过低,保证空调器的出风温度舒适可满足用户的舒适需求。Here, on the basis of the frequency limit value determined by the indoor and outdoor temperature, the second frequency is obtained after adjusting the speed of the indoor fan, which can ensure the reliable operation of the air conditioner and the comfortable indoor temperature, avoid the temperature of the air outlet from being too low, and ensure that the air conditioner The comfortable air temperature can meet the comfort needs of users.
