Why is there no airflow from the air conditioner's heating function?

[LeLucas]

There are several reasons why the air conditioner's heating function may not produce airflow: 1. Improper use or maintenance by the user; 2. A significant increase in power consumption can cause unstable or too low voltage in the local power supply; 3. The air conditioner lacks refrigerant (fluorine); 4. The heating capacity of the air conditioner is insufficient for the room size, resulting in the inability to achieve the desired room temperature, meaning the rated heating capacity is inadequate. Air conditioners are divided into cooling-only and cooling/heating dual-purpose types. The working principle involves the compressor compressing gaseous refrigerant into high-temperature, high-pressure gaseous refrigerant, which is then sent to the condenser. After dissipating heat, it becomes liquid refrigerant at normal temperature and high pressure, which is why the outdoor unit blows out hot air. When water vapor in the air encounters the cold evaporator, it condenses into water droplets that flow out through the drain pipe, which is why the air conditioner produces water.
