Little white must see! Central air conditioning vs. fresh air system, who is more suitable for you? Choosing between central air conditioning and fresh air system is a common confusion among beginners. Both have their strengths, but it depends on individual actual needs.

Central air conditioning adopts a one to many design, with one large unit paired with multiple small units to regulate indoor temperature and achieve a comfortable environment. Suitable for people who spend a whole day in the house and pursue a comfortable life. Central air conditioning ensures temperature balance and high comfort, especially during hot or cold seasons. In addition, the appearance design of central air conditioning is more beautiful, with concealed installation that does not damage the interior decoration style.

But central air conditioning has limitations, mainly in regulating indoor temperature and cannot exchange with outdoor air, which can easily cause indoor air retention, especially for newly renovated housing enterprises.

In contrast, fresh air systems place greater emphasis on indoor air quality. The fresh air system consists of a supply and exhaust system, ensuring indoor and outdoor air exchange and continuously providing fresh air. Especially suitable for newly renovated or households with poor air quality. The fresh air system helps to reduce indoor pollution, such as formaldehyde and dust, making the air fresher.

But the fresh air system cannot regulate indoor temperature, so if you value comfortable temperature, using the fresh air system alone may not be enough.

1.Central air conditioning often adopts a "one to many" design, where one outdoor unit is paired with multiple indoor units to effectively maintain a balanced temperature throughout the house, resulting in an overall aesthetic and energy-saving effect.

2.The fresh air system consists of supply and exhaust systems, and is divided into two modes: ducted and ductless.

2. Comparison of functions between central air conditioning and fresh air systems

Central air conditioning mainly regulates indoor temperature; The fresh air system is responsible for the exchange and circulation of indoor and outdoor air.

3. Limitations of central air conditioning

　　1. The central air conditioning return air outlet cannot exchange with outdoor air.

　　2. Lack of ventilation function makes it difficult to send in fresh air, making it difficult to expel indoor polluted air.

　　3. The fresh air volume is insufficient to meet the standard of changing indoor air every two hours.

　　4. The air supply duct is prone to accumulating bacteria and dust, making it difficult to clean, and there is a problem of secondary pollution.

　　5.The advantages of central air conditioning

　　High comfort, significant energy-saving effect, and strong overall performance.

　　6.The complementarity between central air conditioning and fresh air systems

Indoor air quality is directly related to human health. Although central air conditioning regulates indoor temperature, it can easily lead to carbon dioxide accumulation and insufficient oxygen in enclosed spaces. The addition of fresh air system can ensure indoor and outdoor air circulation without opening windows, provide clean fresh air 24/7, and have a certain air purification effect. In summary, central air conditioning and fresh air systems complement each other. The former is responsible for indoor temperature regulation, while the latter ensures indoor and outdoor air circulation. The two complement each other's functions and jointly create a comfortable and healthy living environment.

So, whether to choose central air conditioning or fresh air system mainly depends on your living needs. If pursuing comfortable temperature, the central air conditioning system is a must-have. But if you care about indoor air quality, fresh air systems are more suitable. Of course, choosing a combination of central air conditioning and fresh air system ensures both comfortable indoor temperature and fresh air, creating a suitable living environment.
