What does an air handling unit do?

The air handling unit (AHU) is the heart of central air conditioning. It collects outside air and room air, removes dust and other particles from the collected air, adjusts the temperature and humidity and then supplies comfortable and refreshing air-conditioned air into the rooms through ducts.

The air handling unit ensures the quality and applicability of air through a series of processes. In general, an air handling unit will use a mixture of outside air and recirculated air from the building to filter, cool, and heat. Energy recovery devices are used to transfer heat or moisture from exhausted air to supply air, or vice versa. This helps to reduce energy usage while providing fresh air to the building.

These processes include drying, pressure regulation, cooling, filtering, etc. to ensure that the air meets specific requirements. Specifically, the function of the air treatment unit can be subdivided into the following points:

1.Dry and pressure regulation: The air pre-processing unit is cooling and cooling through a pipeline with a heat sink. The precipted water drops are discharged through the drainter, and the pressure regulation valve is regulated to ensure the dryness and pressure of the air. This process is important for preventing equipment damage caused by water, improving the reliability and service life of the pneumatic system.

2.Filter: Automatic drainage and air filters are used to remove pollutants such as moisture, oil and dust in the air, prevent these pollutants from damaging the phee and pipelines, and protect the environment from pollution.

3.Energy-saving and intelligent control: The air handling unit has energy-saving function. When a certain pressure is reached, the signal can be given by the control port to reduce the engine load. In addition, it also has an intelligent control system, which can automatically adjust the air parameters according to the actual situation to achieve the effective use of energy.

The air handling unit ensures the quality and applicability of air through its comprehensive function and processing steps. Whether it is in the fields of industrial, commercial, vehicles, or fire safety, it will play an indispensable role.
