The main aim of HVAC systems is to fulfill the thermal comfort of the people by constantly changing the air outside to the ideal conditions of the buildings. Mainly depending upon the external conditions, the air is drawn into the buildings and cooled or heated before it is distributed to the outside space.
The choice of HVAC equipment in any particular building will rely upon the environment, the life of the building, preference of the individual, the budget of the project, the designer of the project, and the architectural, infrastructure design of the buildings. The basic HVAC products convey adapted air to fulfill the comfort of room and people and accomplish the indoor air quality.
HVAC diffusers are characterized as air terminal gadgets that distribute conditioned air in different ways using their deflecting vanes. HVAC diffusers are designed to enhance the mixing of conditioned air with already present air in the space. It is critical to properly mix the adapted air into space, to give cooling/warming and disperse natural air to the whole space, and to maintain a strategic distance from stale air in the space. HVAC diffusers are also helpful to spread air and increase fluid velocity.
