HVAC systems are also known as climate control systems since they control our environment. They are mainly used to control heating and cooling operations in our homes and offices. These systems use air from outside to bring fresh air to indoor spaces. The term HVAC stands for heating, ventilation, and air conditioning. Through the ventilation process, HVAC systems remove air contaminants such as dust, smoke, carbon dioxide, odors, and airborne bacteria. These systems also regulate temperatures, control humidity, and replenish oxygen supply.

The HVAC system has three core processes of heating, ventilation, and air conditioning. Each process has a distinct unit performing the function, and they are all controlled by a common electronic control system.
  • Heating
    To maintain comfortable temperatures in an enclosed space, the HVAC system uses the heating unit to raise the temperatures. The unit is made up of heaters and heat exchangers. The size of the heating unit is proportionate to the size of space that requires heat. For large spaces, you can use boilers, furnaces, steam generators, or heat pumps as the heating unit. For small spaces, the heating unit can be a high resistance carbon ribbon. The heat generated by the heating unit is transferred through the normal processes of convection, radiation, or conduction and is transferred to the air through heat exchangers.
  • Air Conditioning
    The role of the air conditioning unit is to cool the temperatures and maintaining humidity in enclosed spaces. This unit applies the refrigeration process where refrigerants absorb the heat from the surroundings. Refrigerants can be air, water, or other substances. An air conditioning unit comprises a compressor, condensation coil, expansion valve, and evaporator.
  • Ventilation
    The ventilation process works on the principle that air naturally moves from hot areas to cold areas and vice versa. This system is mainly effective in spaces that lack an opening that would facilitate natural ventilation.
