Successful HVAC systems are the key to successful buildings. In a central system, air can be conditioned in a remote location in the air-handling units and distributed to the various rooms by ductwork. Or the air can be conditioned directly in the indoor spaces through fan coil units or other terminal devices. The design of air distribution system must combine a proper choice of engineered products efficiently providing conditioned air to the space while adding architectural features which complement the interior design. A good understanding of the various types of commercial HVAC systems is important to ensure the best fit. This quick book course provides basic knowledge about the HVAC distribution systems in design applications. The course provides insight to various systems, technologies and equipment configuration with advantages and disadvantages. This course is applicable to HVAC engineers, facility engineers, architects, energy auditors, environmentalists, operations and maintenance personnel, as well as consultants and contractors who construct, build and manage facilities.
