AI Technical Summary

Technical Problem

In low-temperature environments, the high pressure of the air conditioner's outdoor fan drops too quickly, causing the low-pressure side temperature to drop too low, triggering the anti-freeze protection and affecting system stability. Conventional adjustment methods are ineffective, and frequent adjustments lead to system instability.

Method used

By obtaining the saturation temperature corresponding to the high pressure of the air conditioner and comparing it with the temperature threshold, the outdoor fan is controlled to increase or decrease its speed to ensure that the high pressure is within a reasonable range. The air volume is also adjusted in conjunction with the filter to stabilize the system.

Benefits of technology

This effectively avoids the need for anti-freeze protection, ensuring the stability of the air conditioner's operation in low-temperature environments and preventing problems caused by system instability and frequent adjustments.

Abstract

This invention provides an air conditioner and its control method, control device, and storage medium. The air conditioner includes an outdoor fan, and the control method includes the following steps: obtaining the saturation temperature corresponding to the high-pressure of the air conditioner; comparing the saturation temperatures T... 高压 With temperature threshold T 阈值 The size of the temperature threshold T is used to control the operating mode of the outdoor fan based on the comparison results. 阈值 Including the first temperature threshold T 阈1 and below the first temperature threshold T 阈1 The second temperature threshold T 阈2 When the comparison result is T 高压 >T 阈1 When the external fan speed is adjusted, the speed of the external fan is controlled; when the comparison result is T 高压 <T 阈2 When necessary, the outdoor fan is controlled to slow down. This invention compares the saturation temperature corresponding to the high pressure with a temperature threshold, and controls the outdoor fan to speed up or slow down based on the result. This allows the high pressure of the air conditioner to be controlled within a reasonable range, ensuring the stability of the air conditioner's operation and preventing the air conditioner from triggering its anti-freeze protection mechanism.
