3. Why does one of the two air vents of the air conditioner produce air while the other does not?

The problem of single-sided air outlet in air conditioning dual vents is usually caused by four common reasons. 1. Mode setting issue: Some air conditioners support the "single-sided air supply" mode. If the remote control is accidentally touched or set incorrectly, it may cause one side of the air outlet to close. You can try switching settings by pressing the "Wind Direction" or "Mode" button on the remote control, and observe whether the dual air outlet is restored. 2. Abnormal air guide plate. When the air guide plate in the air conditioner is stuck by foreign objects or the motor is faulty, it blocks the air outlet and causes one-sided lack of air. You can use a flashlight to observe the status of the air guide plate through the air outlet - if you find that the air guide plate is tilted, shaking, or stagnant, you need to turn off the power and gently reset it. If the problem persists, you need to contact after-sales maintenance. 3. When the air duct is blocked or the dust accumulation on the filter screen that has not been cleaned for a long time exceeds 80%, the evaporator is prone to frosting, causing internal air resistance imbalance. I

t is recommended to clean the filter screen with a soft brush and neutral cleaner every 2 months. During winter heating, the "anti cold air" mode preheating unit can be started to avoid incomplete defrosting caused by alternating cold and hot air. 4. Installation design defects: If the pipeline bends ≥ 90 degrees or the internal baffle falls off during the installation of central air conditioning, it will cause the air distribution ratio of the dual air outlets to be imbalanced. The wind speed of both air outlets can be measured separately through a mobile wind speed detection app (such as AirFlow Meter), and the normal difference should be ≤ 0.5m/s. If the measured wind speed on one side is ≤ 1m/s and there is no obvious airflow, professional personnel need to inspect the air duct. Contemporary air conditioners commonly use dual motor independent control systems, and high-end models from brands such as Gree and Daikin are equipped with air balance self checking functions. When the difference in wind pressure between the two sides exceeds 20%, the machine display screen or APP will trigger E3/E4 fault code prompts. This intelligent diagnostic function significantly improves maintenance efficiency. Avoid hanging obstructions at the air outlet during daily use, and regular maintenance can reduce the probability of such problems by more than 70%.

4. Function of Automobile Air Flow Meter

Air Flow Meter (AFM) is the abbreviation for Manifold Air Flow Meter (MAFM), also known as Air Flow Sensor (AFS). Its function is to detect the amount of intake air into the engine and convert the intake air information into an electrical signal to input into the electronic control unit (ECU) for calculating and determining th
