The difference between central air conditioning and ventilation systems

The main differences between ventilation systems and central air conditioning are reflected in the following aspects

√ Ventilation system: By introducing fresh outdoor air and exhausting indoor dirty air, it improves indoor air quality and provides a healthy and comfortable indoor environment.

→ Central air conditioning: The main function is to regulate the indoor temperature and maintain the indoor temperature at an appropriate level through the refrigeration or heating system

√ Ventilation system: Ventilate, introduce fresh air, discharge polluted air, and reduce indoor secondary pollution

→ Central air conditioning: cooling or heating, adjusting indoor temperature, high comfort and good energy saving effect

√ Ventilation system: Utilizes fan power and duct technology to achieve indoor and outdoor air circulation and ventilation

→ Central air conditioning: through the circulation of refrigerant, the indoor heat is transferred to adjust the temperature.

√ Ventilation system: used all year round, especially necessary in situations with poor air quality

→ Central air conditioning: mainly used in summer and winter for cooling or heating

√ Ventilation system: high air exchange rate, can discharge harmful gases and pollutants in time, and introduce fresh air

→ Central air conditioning: Although it has a certain fresh air function, the air exchange rate is usually low and the air quality is not as good as the ventilation system

√ Ventilation system: including heat exchangers, filters, fans, air supply and exhaust ducts, etc., to achieve air introduction, filtration, heating or cooling

→ Central air conditioning: including compressor, condenser, evaporator, air handler, etc., to achieve air cooling or heating

√ Ventilation system: Suitable for occasions that require a large amount of fresh air, such as high-rise residences, schools, hospitals, offices, etc.

→Central air conditioning: suitable for occasions where a certain indoor temperature needs to be maintained, such as shopping malls, hotels, theaters, etc.

In summary, ventilation systems focus on improving indoor air quality, while central air conditioning is mainly used for temperature regulation. There are obvious differences between the two in terms of functions, principles, equipment structures and applicable scenarios.
