What is HVAC?
HVAC stands for Heating, Ventilation, and Air Conditioning. HVAC refers to the different systems used to move air between indoor and outdoor areas, along with heating and cooling residential and commercial buildings. They are the systems that keep you warm in the winter and feel relaxed and fresh in the summer. They also are the systems that filter and clean indoor air to keep you healthy and maintain humidity levels at comfort levels. The purpose of an HVAC system is more than just warming or cooling a space. Instead, it improves indoor air quality and provides comfort for everyone inside a building. While there are several different HVAC systems, they all begin with the same essentials. First, there is a source of fresh air intake from the outside or from within the home. This process is called ventilation, and it happens in two different ways. Natural ventilation refers to how air typically moves in and out through windows, doors, vents, and other openings. This exchange of air is necessary to provide fresh oxygen and remove carbon dioxide and excessive moisture. Mechanical ventilation uses a mechanical system to move air in and out. In the past, there was plenty of natural ventilation in most homes from gaps and cracks in the construction along with opening and closing of doors.
However, modern construction is creating far more tightly sealed homes, so ventilation is becoming an increasingly important component in home HVAC systems. Once the air is brought in, it is drawn into an air handling unit, where the work begins. The atmosphere is drawn through filters to remove dirt, dust, and particles. Next up is comfort. Air is either sent to be heated or sent to be cooled and have excess humidity removed. Once the air is clean, fresh, and comfortable, it is directed into the home. This means moving through a network of ducts and registers to different rooms for central systems. For other systems, this usually means being directed right into the space.
HVAC simulations in ANSYS Fluent software
The basic theory behind the HVAC modeling process can be explained by coupling the Navier-stokes equation with the energy. The former is used to analyze airflow behavior inside a room or space, while the latter is used to obtain and calculate temperature changes and distribution inside the mentioned space. While these two are the primary modules for solving an HVAC modeling problem, another module that will take your project to a whole new level is implementing species and discrete phase modules. Using these four modules, an HVAC engineer can analyze space from the perspective of thermal comfort, optimal humidity, and contamination control due to the existence of particulate matter alongside predicting the airflow pattern entering and exiting the mentioned space and, therefore, design and impeccable HVAC system.
