What is Duct Split?

Duct splits are one of the most common ventilation systems due to their ability to provide high cooling and heating and efficiency.

This system consists of an internal unit- air conditioner – and an external unit – condenser – connected to each other by copper tubes.

Cooling Cycle

The refrigeration cycle in duct splits is similar to air conditioners and splits, which includes compressors, condensers, expansion valves, operators and refrigerant phase changes.

In this cycle, the cooling gas inside the compressor, which has the role of compressing the compressible fluid by expending mechanical energy, condenses.

And because of this and its high pressure transfer to the condenser, the gas temperature increases significantly.

By transferring to the condenser or condenser, the heat from the bite is taken and converted into a liquid state.

Then, while leaving the condenser and passing through the capillary tube or the expansion valve, the desired liquid undergoes a severe pressure drop, which assumes a two-phase state (liquid/gas) and
Then it is transferred to the operator (evaporator).

In the operator, which is a set of copper pipes and mesh aluminum plates, which is installed in the inner part of the device,

The refrigerant evaporates and becomes a gas, and in the meantime, it transfers its coldness to the operator’s pipes.

The air in the room enters the unit from one side with the rotation of the internal fan impeller and loses its heat by passing through the cooled pipes of the operator.
It is cooled and injected into the desired environment with the help of a built-in fan.

The evaporated refrigerant by the operator is returned to the cycle and condensed by the compressor, and this process continues in the same way.

Heating Cycle

The method of providing heating in duct splits is similar to fan coils in that the flow of hot water supplied by the engine room or the packages enters the device and passes through the coils and heats them.

The temperature of the incoming air flow through the fans increases by passing through the heated coils and is transferred to the desired environment with the help of the built-in fan.
