Embodiment Construction

[0049] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0050] Such as Figure 2-5 As shown, a control method for an inverter air conditioner, comprising steps:

[0051] S1, start the inverter air conditioner, and read the real-time value X of the system operating parameter X n ;

[0052] S2, judging whether the frequency reduction times n or shutdown times m of the air conditioner triggered by the parameter X meet the preset standard within a period of time T1, if so, continue to step S3; if not, the inverter air conditioner maintains the current state and continues to run;

[0053] S3, modifying the threshold value of the parameter X, and the air conditioner enters the protection parameter correction mode;

[0054] S4, the air conditioner operates in the protection parameter correction mod...

Abstract

The invention provides a variable frequency air conditioner control method which comprises the following steps that S1, a variable-frequency air conditioner is started up, and a real-time value Xn of a system operation parameter X is read; S2, whether the frequency reduction frequency n or the shutdown frequency m of the air conditioner triggered by a parameter X meets a preset standard or not within a period of time T1 is judged, if yes, the step S3 continues to be executed, and if not, the variable frequency air conditioner keeps the current state and continues to operate; S3, the threshold value of the parameter X is corrected, and the air conditioner enters a protection parameter correction mode; and S4, the air conditioner operates in the protection parameter correction mode. According to the variable frequency air conditioner control method, self-adaptive control can be achieved through the variable frequency air conditioner control method, frequent frequency increasing and decreasing or starting and stopping are avoided, the operation stability and reliability of the variable frequency air conditioner are improved, and the service life of the variable frequency air conditioner is prolonged.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a control method for an inverter air conditioner. Background technique [0002] Inverter air conditioners have greater advantages in energy saving and comfort because their operating frequency can be automatically adjusted according to changes in indoor loads, and have become mainstream products in the market. In addition, the inverter air conditioner can also automatically reduce the frequency of the compressor to operate under severe working conditions or when certain operating parameters are protected due to objective factors to ensure that the system parameters operate within a reasonable range, which greatly improves the reliability of the whole machine. sex and longevity. [0003] However, the frequency conversion control logic of the inverter air conditioner is not perfect at present, especially when the protection is carried out by some operating parameters with lag, such...
