What is a duct air conditioning?

Duct air conditioning generally refers to a form of central air conditioning, which delivers cold (hot) air to each room by connecting air supply ducts. This type of air conditioning is usually used in local spaces, such as a single office or living room. Its installation is relatively simple and the cost is low. Duct air conditioning is generally in a one-to-one form, that is, one outdoor unit corresponds to one indoor unit, and the cold (hot) air is distributed to different areas by connecting air supply ducts. Compared with central air conditioning, central air conditioning adopts a one-to-many form, that is, one outdoor unit is connected to multiple indoor units, and the indoor and outdoor units are connected by refrigerant pipes. It is suitable for large buildings, such as office buildings, shopping malls, etc., and can provide unified temperature control for multiple rooms or areas.

The advantages of duct air conditioning include good comfort, strong energy saving and easy installation. Due to the use of variable frequency technology, duct air conditioning can automatically adjust the output of the outdoor unit according to the indoor temperature and humidity, thereby achieving a more energy-saving and environmentally friendly effect. At the same time, since it does not require a large area of ceiling like a multi-split unit, it saves space and costs. However, the disadvantages of duct air conditioning include the need for professional installation and maintenance, because its structure is relatively complex, and once a problem occurs, the maintenance cost may be high.

In general, duct air conditioning is an air conditioning system that distributes cold (hot) air through air supply ducts, and is suitable for local spaces with specific temperature control requirements. The main difference between it and central air conditioning is its structure and applicable scenarios. Central air conditioning is more suitable for large buildings, while duct air conditioning is more suitable for small local spaces.
