When decorating a new house or purchasing home equipment, air conditioning is almost a must consider, but facing the various brands and models in the market, many people may feel confused and hesitant. Especially for duct ACs and multi split VRF systems, many people cannot understand the difference between these two products because their indoor air outlets look the same. Today, let's take a look at the differences between duct ACs and multi split VRFs?
Duct AC
Duct AC is the abbreviation for duct air conditioning unit, corresponding to multi split unit, also known as VRF. In terms of external form, the internal unit, like the VRF, needs to be installed inside the ceiling and deliver air to the interior through the air outlet. The difference is that the air duct unit is 1 to 1, i.e. 1 outdoor unit and 1 indoor unit, which is essentially not much different from a wall mounted split AC or a free-standing air conditioner.
The advantages of air duct ACs compared to wall mounted split ACs are space saving and more flexible installation. But because the air duct unit is 1 to 1, if air conditioning needs to be installed in several rooms, there will be more external unit positions required. In addition, the budget invested in the early stage of the air duct AC is slightly lower compared to the VRF, and the installation process is also simpler.
VRF
As the name suggests, VRF refers to the connection of multiple indoor units to one outdoor unit, also known as "1 to multi". One outdoor unit can simultaneously control multiple rooms or the entire building to achieve consistent temperature and humidity.
VRFs can be paired with longer piping, and indoor unit selection is more diverse. Moreover, DC frequency conversion is commonly used, which saves energy. Overall, the control is more precise, the technical content is higher, and indoor units can achieve more control functions, but the price is also higher compared to duct ACs.
Duct ACs are now more commonly used by manufacturers as a product for transitioning from single unit air conditioning to multi split central air conditioning. The functions are relatively simple, but with the continuous development of technology, the functions of duct ACs have become increasingly rich, and even in terms of user experience, they are very close to VRFs.
