What is An Exhaust Fan with A Humidity Sensor?
- Definition: Aosun humidity extractor fan is a device that integrates dehumidification and exhaust functions. Essentially, it is an exhaust fan equipped with a humidity sensor. It can not only effectively reduce environmental humidity like a professional dehumidifier, but also be used independently as a fan to promote air circulation, which achieves dual functions in one machine and improves energy utilization efficiency.
- Working Principle: When the device detects an increase in air humidity, its built-in fan will draw in the moist air, and the water vapor in the air will condense into water droplets as it flows through the evaporator, achieving dehumidification. During this process, the air temperature rises, and then it passes through the condenser for partial heat recovery. Finally, the treated dry air is blown out of the machine by the fan, completing the entire dehumidification and air supply process.
Advantages of Humidity Extractor Fans
Dehumidification
Our humidity extractor fan is equipped with a built-in humidity sensor that can actively reduce the indoor air humidity. Its internal refrigeration system reduces the surface temperature of the evaporator to below zero. When moist air flows through, water vapor quickly condenses into water droplets and is collected in the water tank, effectively reducing the moisture in the environment and preventing furniture from getting moldy or deformed due to moisture erosion.
Ventilation
Aosun humidity extractor fan has the ability of forced air circulation. Its built-in fan can not only expel the dried air but also stir and mix the indoor air, achieving effective local ventilation and avoiding dampness in the corners.
Energy Saving
The humidity extractor fan achieves “dual functions in one machine”. You don’t need to purchase separate dehumidifiers and circulating fans at the same time. This not only saves you purchase and installation costs but also reduces the occupied space. In addition, it also supports a low-power air supply mode, which is more energy-efficient compared to starting large appliances.
Intelligent Control
Our humidity extractor fan can be equipped with an intelligent control system. You can set the target humidity, wind speed, and timed on/off through the panel or the mobile phone APP. It will automatically monitor the environment and adjust the operating status to achieve precise dehumidification and energy-saving operation, which greatly enhances your convenience and comfort in use.
How to Choose A Suitable Humidity Extractor Fan?
Core Parameters
- Exhaust Air Volume: You need to calculate the required exhaust air volume value (unit: m³/h) based on the size of the room and the degree of humidity. Generally, the larger and more humid the space is, the higher the required exhaust volume will be. When making your choice, you should leave a certain margin on the basis of the calculated values to ensure that the ideal dehumidification speed can be achieved in actual use.
- Noise: The noise level is related to your comfort during use, especially when used in an environment that requires quietness. Noise is measured in decibels (dB), and the lower the value, the quieter the operation. It is recommended that you give priority to choosing models with operating noise below 40 decibels. This way, even when used at night, it will not disturb your rest.
- Power: Power and energy efficiency are related to the power consumption and economy of a product. You should choose products with moderate power or energy-saving labels under the premise of meeting the exhaust volume and noise requirements to achieve efficient dehumidification and low energy consumption.
Product Configuration
- Humidity Sensing: You should choose a fan equipped with a humidity sensor. It can automatically monitor the humidity changes in the environment. Once it exceeds the safety threshold you have set, it will start automatically. When the humidity drops to a reasonable range, it will automatically shut down. The entire process does not require manual intervention and is particularly suitable for spaces that need to remain dry continuously.
- Check Valve: The check valve is an indispensable key configuration of a humidity extractor fan. It only allows indoor air to be discharged outward, but effectively prevents outdoor cold air, dust, and mosquitoes from flowing back into the room through the air duct. You need to ensure that the product is equipped with a high-quality check valve, which is the foundation for guaranteeing the dehumidification effect and maintaining the cleanliness of the indoor environment.
- Delayed Shutdown Function: After you turn off the fan switch, this function will allow the device to continue to run automatically for a preset period of time, ensuring that after generating a large amount of moisture, the remaining water vapor can also be completely discharged outdoors, avoiding the accumulation of moisture in a closed space.
Protection Level
When choosing a humidity extractor fan, you need to consider its protection level. Generally, it is used in high-humidity environments, so you need to select a fan with an appropriate protection level (IP), which means it has water and dust resistance and can operate safely and reliably even in a humid environment.
Installation and Maintenance
You need to consider a model that matches the installation conditions when choosing a humidity extractor fan, ensuring that the exhaust duct can directly lead to the outside and does not allow damp exhaust gas to enter the mezzanine area, thereby ensuring the dehumidification effect and the safety of the building.
In addition, for later maintenance, you should choose a design where the panel and impeller are easy to disassemble, and regularly clean the dust on them to maintain their best performance. At the same time, it is necessary to check whether the check valve is flexible to prevent it from getting stuck and causing functional failure.
Applications of Humidity Extractor Fans
Bathroom
In a place like the bathroom where there is a lot of moisture and mold is prone to occur, our humidity extractor fan can quickly remove the high-temperature moisture produced after taking a shower to reduce the humidity of the space, prevent fogging on mirrors, mold growth on walls and moldy towels, and keep the floor dry at the same time, which greatly enhances safety.
Kitchen
Aosun humidity extractor fans can help expel the damp air in the kitchen, prevent cabinets and food seasonings from deteriorating due to moisture, and suppress mold in corners such as corners and ceilings, which is conducive to maintaining a clean kitchen environment.
Storage Room
Placing a humidity extractor fan in a sealed wardrobe or storage room can continuously create a low-humidity environment, protecting leather goods and textiles from moisture, solving problems such as yellowing, spotting, and unpleasant odors on clothes.
Basement
The basement has poor ventilation, is rather damp, and prone to mold. Our humidity extractor fans can remove the moisture inside, protecting the stored tools, cartons, and electronic products from getting damp, rusting, deforming, or being damaged.
