HVAC Distribution 15 PDH Discount Package

This online engineering PDH 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.

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. Alternatively, 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 6 PDH online 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.

This online engineering PDH course discusses the history of chilled water distribution systems and the development of "variable primary flow system". Problems such as low delta-T syndrome associated with the chilled water pumping schemes are defined and also discussed. Finally, this course compares the advantages and disadvantages of primary-secondary and direct-primary pumping schemes.

In large commercial and industrial systems, chilled water system serves as means to transfer heat from building spaces to the refrigeration system. Initially, when energy costs were low, constant volume and primary-secondary systems provided a stable and simple operation of the chillers and distribution systems. However, as energy costs increased, particularly in the late 1970s, the efficiency of the chillers and the costs associated with operating the distribution system became more important. As a result, the need for new schemes to improve chiller performance and reduce energy costs drove the HVAC industry to advance chilled water technology, particularly in the manner that chilled water is delivered.

This 5 PDH online course is applicable to mechanical and HVAC engineers, process engineers, architects, building designers, contractors, energy auditors, facility managers who are interested in gaining a better understanding of HVAC chilled water distribution schemes.

This online engineering PDH course discusses how the UFAD system differs from the conventional HVAC design and reviews several key design issues pertinent to UFAD design.

Underfloor air distribution (UFAD) turns air supply upside down, allowing a floor plenum to deliver conditioned air to the space via floor diffusers in the raised floor system. The floor plenum typically consists of pedestals and removable floor panels that can be rapidly reconfigured. The space is divided into two zones: an occupied zone extending from the floor to head level, and the unoccupied zone extending from the top of the occupied zone to the ceiling.

The systems are designed to condition the lower occupied zone only and the temperature conditions in the upper zone are allowed to float above normal comfort ranges. The fact that conditioned air is delivered at floor level do provide energy savings while improving comfort and indoor air quality. While this strategy is most effective in new construction, it also can work in major retrofits. Thoughtful design is the key to successful application.

This 4 PDH online course is intended for mechanical and HVAC engineers, architects, building designers, contractors, civil estimators, energy auditors, facility managers and general audience interested in gaining a better understanding of underfloor air distribution systems. No specific prerequisite training or experience is required.
