HVAC (also known as ventilation system) stands for Heating, Ventilating, Air Conditioning. The system includes heating, ventilation and air conditioning systems.

Purpose of using ventilation system:
Adjust room temperature.
Provide cool air for the room.
Remove contaminants from the air by using filters at different stages.
Effective material activities.
The structure of the HVAC system
1. Heating System
The main use of this system is to generate humidity in buildings and commercial centers.
The general construction of the heating system consists of:
Boilers
Fireplaces or heat pumps: For heating water, steam or possibly air at a central location such as a fireplace room in a house, a mechanical room in a large building. The heat can be transferred by convection, thermal conductivity or radiation.
2. Ventilation system
This system is responsible for changing the airflow in any space to control temperature or to remove any humidity, odor, smoke, heat, dust, or bacteria inside the air or CO2. and supplementary oxygen. In addition, the ventilation system also includes the exchange of airflow with the outside as well as inside the building.
Ventilation is considered to be one of the most important factors in maintaining the quality of air inside each building.
There are two methods of ventilation
Ventilators
Natural ventilation.
3. Air Conditioning
Air conditioning will provide pre-installed airflow and humidity for the building. Buildings with air conditioning are usually sealed, opening the window will reduce the cooling effect from the system.
Air-conditioning and refrigeration are usually created by removing heat from the inside of the system. The temperature of the air can be removed by radiation, convection or transmission through a chiller. Some means of cold transmission such as water, air, ice, chemicals or collectors are called refrigerants. These refrigerants are used in the heat pump system, in which the compressor is used to control the thermodynamic cooling cycle, or in a cooling system using a pump for transport. Transfer a coolant (usually water or a glycol mixture).
The operational cycle of the HVAC system
Supply Air: Provide air, including cold air and hot air.
Return Air: Bring the air back.
Exhaust Air: Exhaust air is not clean out.
