What is Duct Split?
Duct split, like wall splits, consists of two main parts: external unit (condensing unit) and internal unit (air-generating unit). As it can be seen from the name of split duct, it is the same split with newer technology and its heat transfer system is through ducting or air vent.
1-Duct Split Air Force Unit
The air-generating unit or indoor unit is responsible for air distribution between the spaces, which may be done directly or channeled through the valve according to the capacity and use. Split duct installation is usually done in the false ceiling of the building.
2-Condensing Duct Split
The condensing unit or external unit is responsible for the main task of producing cooling through the compressor, which is connected to the internal unit using insulated copper pipes and energy exchange is done. According to various factors, the external unit is installed on the balcony (terrace) or roof and sometimes to create a roof garden on top of the building.
In some duct split models, there is the ability to heat and cool by refrigerant gas and heat pump, which in our country, due to the more economical use of gas energy in cold seasons, hot water coils are used inside the device for heating. It is possible that the hot water consumed after energy exchange and cooling is reheated by the package or hot water boiler connected to the device through piping. In this case, the duct split device works like a fan coil and only the fan part of the device is turned on. The main consumer of electricity in split and duct splits is the external unit of the device, which is switched off during heating and using the hot water coil in winter, and the internal unit plays the role of a fan, which greatly reduces electricity consumption. It happens in winter. Below is an example of a split channel with a description of the main parts.
