Problems solved by technology

At this time, the air conditioner shutdown protection will not be able to perform cooling, which will affect the comfort of the indoor temperature.
That is, if the outdoor temperature detected by the temperature sensor is used as the control temperature, the control accuracy is poor.
On the other hand, when it is detected that the outdoor temperature reaches the set high temperature, the control air conditioner will stop running immediately, which will also affect the comfort of the indoor temperature due to the inability to cool.

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] See figure 1 , which is a flowchart of an embodiment of the air conditioning control method of the present invention.

[0031] Such as figure 1 As shown, the method for controlling the air conditioner in this embodiment includes the following steps:

[0032] Step 101: Obtain the output voltage value corresponding to the working temperature of the variable frequency power module in real time, and compare the output voltage value with the set voltage value.

[0033] As mentioned in the background, the variable frequency power module refers to the power module that realizes the frequency change in the variable frequency air conditioner, and is the main and most important heating module in the air conditioner circuit board. When the air condi...

Abstract

The invention discloses an air conditioner control method which comprises the following steps: acquiring an output voltage value corresponding to the working temperature of a frequency variable power module in real time, and comparing the output voltage value with set voltage values; if the output voltage value is not less than a first set voltage value, controlling an air conditioner compressor to stop; and if the output voltage value is less than a first set voltage value but is not less than a second set voltage value, carrying out the following frequency limiting process: limiting the working frequency of the compressor, which is acquired according a conventional frequency calculation method, and controlling the compressor to operate by taking the limited working frequency as an actual working frequency. Through application of the control method provided by the invention, the accuracy of control temperature detection and the comfort of air conditioner temperature regulation are improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioning control method. Background technique [0002] In hot summer, the outdoor temperature in many areas often reaches above 30°C, and when the air conditioner is running, the outdoor unit will continue to dissipate heat. Therefore, the temperature of the outdoor unit of the air conditioner is often higher than the outdoor temperature. Under high temperature, the cooling effect of the air conditioner is greatly reduced, and there may even be a strike phenomenon of "high temperature jump stop". These objective environments pose higher challenges to the cooling capacity of the air conditioner. [0003] Inverter air conditioners have become the first choice of users because of their advantages such as fast temperature adjustment speed, high temperature control accuracy, low operating noise and low energy consumption. A core component of the invert...
