However, this control method is mainly used to ensure the cooling and heating effect of the air conditioner, but has a large power consumption.
In order to solve the above problems, the present invention provides a method for controlling the power limit of an air conditioner, as shown in fig. 1 and 2.

After the set temperature Ts, the indoor temperature Tn and the outdoor temperature Tw are obtained, the electricity-limiting adjusting parameters of the air conditioner can be determined according to the temperature difference value of the indoor temperature Tn and the outdoor temperature Tw and the calculation of empirical parameters. The electricity limiting adjustment parameters can enable the air conditioner to reduce the power consumption to the minimum on the basis of ensuring the cold and hot effect.
Wherein, the operation parameter that the temperature difference value of injecing the regulating parameter for present indoor temperature Tn and outdoor temperature Tw needs to be adjusted, the electricity limit regulating parameter is similar with the operation parameter of setting for, mainly includes: compressor frequency reduction parameters delta P, indoor and outdoor fan speed reduction parameters delta F, expansion valve closing parameters delta K and the like.

If the first temperature difference interval is matched, the power-limiting operation parameters are as follows: the compressor frequency P' = P-P1 is defined. The indoor unit wind speed Fn' = Fn-F1 is defined. The outdoor unit wind speed Fw' = Fw-F1 is defined. The expansion valve opening degree Km' = Km-K1 is defined.
The compressor frequency reduction parameter corresponding to the second temperature difference interval is P2, the indoor and outdoor fan speed reduction parameter is F2, and the expansion valve closing parameter is K2. Wherein, K1=60 degrees, F1=100 turns, and P1=10hz.
If the second temperature difference interval is matched, the power-limiting operation parameters are as follows: the compressor frequency P' = P-P2 is defined. The indoor unit wind speed Fn' = Fn-F2 is defined. The outdoor unit wind speed Fw' = Fw-F2 is defined. The expansion valve opening degree Km' = Km-K2 is defined.
The compressor frequency reduction parameter corresponding to the third temperature difference interval is P3, the indoor and outdoor fan speed reduction parameter is F3, and the expansion valve closing parameter is K3. Wherein, K1=30 degrees, F1=50 turns, and P1=5hz.
If the third temperature difference interval is matched, the power-limiting operation parameters are as follows: the compressor frequency P' = P-P3 is defined. The indoor unit wind speed Fn' = Fn-F3 is defined. The outdoor unit wind speed Fw' = Fw-F3 is defined. The expansion valve opening degree Km' = Km-K3 is defined.
By the aforesaid, this embodiment has set up three limit for electricity adjustment parameter, and is less when indoor outer difference in temperature, then compressor operating frequency reduces great, and the wind speed reduces great, and the valve opening reduces great to this makes the air conditioner power saving operation. When the temperature difference between the indoor and the outdoor is large, the running frequency of the compressor is reduced less, the wind speed is reduced less, the opening degree of the valve is reduced less, and the air conditioner can run in a power-saving mode on the basis of ensuring the cold and hot effects.
In another embodiment provided by the present invention, to improve the sensitivity of the adjustment, step S130: the specific steps of determining the electricity-limiting adjustment parameters of the air conditioner based on the temperature difference between the indoor temperature and the outdoor temperature comprise:
step S1304: and acquiring the temperature difference between the outdoor temperature and the indoor temperature.
Step S1305: based on the temperature difference and the operating mode, an electrical limit set temperature is determined.
For the convenience of calculation, the absolute value of the temperature difference between the outdoor temperature Tw and the indoor temperature Tn is calculated to determine the range of the indoor and outdoor temperature differences.
And after the temperature difference is determined, determining the electricity-limiting set temperature according to the operation mode of the air conditioner, so that the air conditioner is controlled by the electricity-limiting set temperature during subsequent work.

And after the power limit set temperature Ts 'is obtained, determining a power limit adjusting parameter corresponding to the power limit set temperature Ts' according to the controlled operation mode.
Wherein the absolute value of the temperature difference is inversely related to the power limiting adjustment parameter. The electricity-limiting adjusting parameter can be an optimal operation parameter under the electricity-limiting set temperature Ts ', and can directly obtain the limited compressor frequency P ', the limited indoor unit wind speed Fn ', the limited outdoor unit wind speed Fw ' and the limited expansion valve opening Km '.
