How to use the dehumidification function of air conditioner
With the arrival of summer, the dehumidification function of air conditioners has become the focus of attention for many families. Dehumidification can not only reduce indoor humidity, but also improve comfort, but many people don’t know how to use this function correctly. This article will introduce in detail how to use the dehumidification function of the air conditioner, applicable scenarios and precautions to help you make better use of this function.
1. Principle of dehumidification function of air conditioner

The dehumidification function of the air conditioner is to achieve the dehumidification effect by lowering the air temperature and causing the water vapor in the air to condense into water. Simply put, when operating in dehumidification mode, the air conditioner will operate at a lower wind speed while maintaining a lower evaporator temperature, making it easier for moisture in the air to condense.
| mode | Working principle |
|---|---|
| cooling mode | Cooling effect is achieved by quickly lowering the temperature, and the wind speed is higher |
| Dehumidification mode | Run at low speed to keep the evaporator cool and allow moisture to condense |
2. Applicable scenarios for air conditioner dehumidification function
The dehumidification function is suitable for high humidity environments, especially during the rainy season or humid summer. Here are some common applicable scenarios:
| scene | Description |
|---|---|
| rainy season | The humidity is high and the clothes are not easy to dry. This can be improved by using the dehumidification function. |
| basement | Poor ventilation, prone to moisture, dehumidification function can reduce musty smell |
| southern region | Humidity is high in summer, and the dehumidification function can improve comfort |
3. How to correctly use the dehumidification function of air conditioner
1.Choose the right temperature: In dehumidification mode, it is recommended to set the temperature between 24-26°C. Too low will lead to excessive dehumidification, which will make people feel dry.
2.Control usage time: Turning on the dehumidification mode for a long time may cause the indoor temperature to be too low. It is recommended to turn it off every 2-3 hours to let the air conditioner rest.
3.Use with ventilation: In weather with high humidity, windows can be opened appropriately for ventilation to prevent the indoor air from being too closed.
| Operation steps | Things to note |
|---|---|
| Turn on dehumidification mode | Avoid using it simultaneously with cooling mode |
| Set appropriate temperature | Too low temperatures may affect comfort |
| Clean the filter regularly | Ensure dehumidification effect and air quality |
4. Frequently Asked Questions about Air Conditioner Dehumidification Function
1.Does dehumidification mode consume electricity?: The power consumption of dehumidification mode is usually lower than that of cooling mode, but long-term use will still increase the electricity bill.
2.Can dehumidification mode replace a dehumidifier?: For ordinary households, the dehumidification function of air conditioners is sufficient, but in extremely humid environments, professional dehumidifiers are more effective.
3.Why is the wind speed in dehumidification mode low?: Low-speed operation is to allow air to fully contact the evaporator and improve dehumidification efficiency.
5. Summary
The dehumidification function of air conditioners is very practical in humid environments, but care must be taken to use it rationally and avoid excessive dehumidification or long-term operation. With correct temperature settings and regular maintenance, you can maximize its effectiveness and improve your home comfort. I hope this article can help you make better use of the dehumidification function of your air conditioner and spend a dry and comfortable summer.
