Mechanism Of Air Circulation
Air circulation in HVAC systems involves the intake of external air via the ventilation system. The air is subsequently filtered, conditioned, and transported throughout the building via ductwork. Air circulation ensures that indoor temperatures and ventilation remain stable.
Myth Busting: External Air Intake
Reality Of Outdoor Air Use
HVAC systems frequently bring in outside air to preserve indoor air quality, contrary to popular belief that they only recirculate indoor air. This fallacy originates from a misunderstanding of the role of external air intake in HVAC systems.
Factors Influencing Outside Air Utilization
Several factors determine the extent to which HVAC systems use outside air, including local air quality, weather conditions, and the system’s design and capacity. These elements are critical in defining the optimal balance of energy efficiency and indoor air quality.
Design Variations In Hvac Systems
Heating, ventilation, and air conditioning (HVAC) systems control indoor temperature, humidity, and air quality. These systems come in a variety of designs to suit the type of building, environment, and budget. One of the most important design changes in HVAC systems is the supply of air. HVAC systems can draw air from within or outside the structure, or both. In this post, we will look at the many types of HVAC systems that receive air from outside.
Types With Outdoor Air Intake
HVAC systems that draw air from outside are intended to improve indoor air quality by introducing fresh air. These systems are appropriate for buildings located in locations with low pollution and moderate weather. The types of HVAC systems that get air from outside include:
| System Type | Description |
|---|---|
| Single Duct | The space receives air through a single duct that combines outdoor and inside air. |
| Dual Duct | Air enters the space via two ducts, one for outdoor air and one for internal air. Mixing the two streams regulates the air’s temperature and humidity. |
| Mixed Air | Air is delivered to the room via a single duct, but temperature and humidity are controlled by mixing outdoor and inside air in a separate chamber. |
Systems Relying Solely On Indoor Air
HVAC systems that rely only on interior air are designed to circulate air within the building rather than bringing in fresh air from outside. These systems are appropriate for buildings located in locations with high pollution levels or extreme weather. Examples of HVAC systems that rely primarily on indoor air include:
- Constant Volume
- Variable Air Volume
- Chilled Beam
In conclusion, HVAC systems that draw air from outside are intended to improve indoor air quality by bringing in fresh air. The climate, pollution levels, and budget all influence the type of HVAC system that is most suited to a particular building. Understanding the various design variants in HVAC systems allows building owners to select the best system for their needs.
