HVAC stands for ‘Heating, Ventilation and Air Conditioning’. Although, AC is the last part that is, Air Conditioning that means when we talk about AC, we usually mean the system at buildings that cools the air. But, when say HVAC, we could be talking about a system that does both the heating and the cooling. Or any either one of them.
The HVAC System provides cooling and heating services to homes, offices, and buildings. HVAC services have now become the industry standard required for construction of new buildings.
How does HVAC System Work?
All HVAC systems are not the same, most of them work on some similar underlying principles. Energy effective HVAC systems consist of plenty of moving parts:
The most visible part of the HVAC system is the thermostat. It is the portion you’ll have interaction with the most. It is typically installed on easily approachable walls, it is set manually and functions to keep your place at an ideal temperature. The thermostat prompts the HVAC system to circulate air as required, as soon as the temperature becomes too hot or too cold.
Known as to be the star of the HVAC system, and it is usually huge—it needs the most is out of all the other components. The primary purpose of the furnace is the heating of air, which is then distributed to different rooms of your home via a ductwork or piping. Furnaces commonly use various heat sources, like heat pumps, solar energy, combustion, and electric resistance.
3. EVAPORATOR COIL:
When the thermostat is set to a lower temperature, the evaporator coil works to cool down the air and channel it throughout the place.
4. CONDENSING UNIT:
Set up on the outdoor of your home and filled with refrigerant gas. When the refrigerant is cooled, the condensing unit pushes the liquid to the evaporator coil to be converted into gas again.
The vents support the distribution of heated and cooled air from the duct system into the different areas of the place. They’re usually installed near by ceiling and send the air downward. It’s important to confirm that these vents get never blocked.
6. REFRIGERANT LINES:
The refrigerant is carried to the condensing unit in the form of gas over these lines. The gas is then shifted back to the evaporator coil after being converted into liquid form.
