In a central air conditioning system, chilled water flows from the chiller through pipes to the AHU system, and from the AHU, it is transferred to the rooms using air conditioning. So, what is an air handling unit or what is an AHU system? What is the AHU structure, and what is the operating principle of the AHU, and what is the schematic diagram of the chiller system?

These devices promise to provide people with a cool, clean, and fresh space. Let’s explore the information related to the AHU system in the article below.
What is an HVAC system?
Heating, Ventilation, and Air Conditioning is the full form of the abbreviation HVAC – HVAC system. These terms refer to a system that provides heating, ventilation, and air conditioning for a room.
HVAC is an integrated system responsible for controlling temperature, humidity, and air quality. The requirement is for the air in a certain space, such as houses, factories, or vehicles, to reach a suitable level.
To avoid monotony, we will alternate between terms like HVAC and air conditioning in this article.
Industrial HVAC systems are designed to provide standard levels of air quality and temperature in a specific area. The design of HVAC systems is based on heat transfer, thermodynamic principles, and fluid mechanics.
Industrial HVAC systems have become a standard in the construction industry with many common applications.
Industrial HVAC systems are installed in: air conditioning and ventilation systems in high-rise buildings, commercial centers,… Or air conditioning systems used in power plants, aircraft, spacecraft, or cleanrooms.
Explanation of some abbreviations in HVAC you should know:
What is an HVAC system?
An HVAC system is a system used for heating, ventilation, and air conditioning in a room.
In other words, an HVAC system is an air conditioning system. It works based on thermodynamic principles, fluid mechanics, and heat transfer.
What is an HVAC engineer?
An HVAC engineer is a professional responsible for tasks related to HVAC systems for heating, air conditioning, and ventilation.
Currently, this profession is divided into 2 types:
- HVAC engineers specializing in air conditioning for industrial applications, working in large factories.
- Civil HVAC engineers specializing in smaller-scale applications such as education, healthcare, forestry, and agriculture.
What is Air conditioning?
- Air conditioning is the process of controlling the temperature, humidity, and air quality in a room.
What is an Air conditioner?
- The answer: An air conditioner is a machine that provides air conditioning.
HVAC system structure, principle, and components
- HVAC systems are designed to meet the specific needs of each area, so almost every project has a different HVAC system design.
- However, in general, an air conditioning system consists of 3 main parts:
Heating system
- The heating system is responsible for generating heat and humidity, including boilers and furnaces (or heat pumps).
- Heating systems are often used to heat water, steam, or air at a central location in the building.
- Heat is transferred by convection, conduction, or radiation. (Due to Vietnam’s tropical monsoon climate, most businesses and production facilities rarely use heating systems).
Ventilation system
- The Ventilation system is responsible for circulating air to replace stale air in the space. The purpose is to control temperature or remove pollutants such as humidity, odors, heat, smoke, dust, bacteria, mold, spores, CO2,… in the air of the area to be cleaned.
- In addition, the air conditioning ventilation system also includes the exchange of air inside and outside the building.
Air Conditioning
The Air Conditioning system is responsible for removing heat generated from within the HVAC system. Air temperature is removed by radiation, convection, or by circulating air through a cooling device.
Heat pump systems have a compressor used to control the cooling cycle using thermodynamics. Here, refrigerants such as water or glycol mixtures are transported by the pump.
Depending on the needs and level of use of each project, HVAC systems are designed accordingly.
