This online engineering PDH course discusses the information needed to design the air distribution system to deliver the proper amount of conditioned air to a space in an energy efficient house.
The heating, ventilation, and air-conditioning (HVAC) system is arguably the most complex system installed in a house and is responsible for a substantial component of the total house energy use. A properly sized HVAC system will provide the desired comfort and will run efficiently. Right-sizing an HVAC system includes the selection of equipment and the design of the air distribution system to meet the accurate predicted heating and cooling loads of the house. This process begins with an accurate understanding of the heating and cooling loads on a space; however, a full HVAC design involves more than just the load estimate calculation; the load calculation is the first step of the iterative HVAC design procedure.
This 3 PDH online course is intended for mechanical engineers, architects, contractors and other professionals interested in learning more about air distribution and duct design for energy efficient homes.
- Learning the different terminologies and concepts of HVAC systems that relate to air distribution
- Understanding the performance criteria related to air distribution systems, which include temperature mixing and uniformity, supply outlets, and noise considerations
- Understanding the design benefits of integrating the HVAC system into the early schematic design phase of the house
- Familiarizing with the design principles of distribution systems, which include pressure drop, supply requirements, return air design, supply air outlets, duct layout, and duct sizes
This online engineering PDH course describes the importance of duct sealing with respect to saving energy in air delivery systems in commercial buildings. This course also explains that the duct sealing method analyzed in this report is technically viable; however, more work is needed to develop a practical cost effective methodology for this process.
Considerable research has been conducted on the leakage levels of various types of ducts and duct fittings. Electricity energy savings potential by eliminating air leakage from ducts in large commercial buildings is on the order of 10 kWh/m2 per year. The research discussed in this paper is based on two large commercial buildings, using a new technology that simultaneously seals duct leaks and measures effective leakage area of ducts.
This 2 PDH online course is applicable to mechanical engineers who design duct systems and write specifications for ductwork sealing in large commercial buildings.
- The importance of duct sealing to safe energy
- The practicality of using aerosol based duct sealants in commercial systems
- Issues related to researching duct sealing methods
- Effective leakage area evaluation criteria
- Aerosol concentration measurements
In this professional engineering CEU course, you need to review the material contained in LBNL Publication, "Duct Sealing in Large Commercial Buildings with Aerosolized Sealant Particles", LBNL 42414.
This online engineering PDH course presents basic information about the various types of duct systems, their classification and application. It also explains the factors involved when sizing duct to comply with specified building requirements. Furthermore this course illustrates the procedures and steps of how to balance duct systems.
To deliver conditioned air to a space, you need air carriers. These carriers are called ducts. They are made of sheet metal or some other structural material depending on their application.
This 2 PDH online course is applicable to engineers, designers, manufacturers and anyone interested to gain an understanding of duct systems.
- Understanding the classification of ducts
- Familiarizing with the duct material of construction
- Understanding the different types of duct systems
- Learning how ductwork is constructed
- Understanding the factors involved in sizing ductwork
- Learning how to balance duct systems
In this professional engineering CEU course, you need to review Chapter 13 of the Naval Education and Training Professional Development and Technology Center “Utilitiesman (Advanced)” NAVEDTRA 14259 - training course.
Once you complete your course review, you need to take a multiple-choice quiz consisting of fifteen (15) questions to earn 2 PDH credits. The quiz will be based on this NAVEDTRA publication.
This online engineering PDH course describes duct thermal performance as evaluated in this report which focused on large commercial buildings. The course discusses the effects of duct deficiencies, duct performance principles such as air leakage, fan performance and heat transfer. In addition the student will gain an understanding of the California Title 24 Duct Systems Compliance Path.
Despite the potential for significant energy savings by reducing duct leakage or other thermal losses from duct systems in large commercial buildings, California Title 24 has no provisions to credit energy-efficient duct systems in these buildings. The overall goal of the Efficient Distribution Systems (EDS) project within the PIER High Performance Commercial Building Systems Program is to bridge the gaps in current duct thermal performance modeling capabilities, and to expand our understanding of duct thermal performance in California large commercial buildings.
This 2 PDH online course is applicable to mechanical engineers who perform HVAC system designs and wish to understand more about how to reduce energy by reducing duct leakage and other thermal losses from duct systems in buildings.
- California Title 24 Duct Systems Compliance Path overview
- Effects of duct deficiencies
- Duct performance principles - air leakage, fan performance, heat transfer
- Duct modeling simulation programs
In this professional engineering CEU course, you need to review the material contained in Duct Thermal Performance Models for Large Commercial Buildings, LBNL-53410 October 2003.
This online engineering PDH course reviews the above criteria in detail and provides guidance on the planning, layout and sizing of supply and return air ducts.
In air conditioning systems the duct is considered a static component of the installation through which air flows within the building, connecting all parts of the system. Ducts can be best described as arteries of the central air-conditioning system. These play an important role in keeping the whole HVAC system fit and achieving comfortable conditions throughout its life span.
Defects in a duct system can waste hundreds of dollars a year by forcing the HVAC system to run longer than necessary. Ductwork problems also make certain rooms too hot or too cold at different times of the year, while introducing dirt and bad odors into the forced-air system.
The objective of good duct design is to:
Optimize duct size (manufacturing costs);
Minimize duct system friction losses (operational cost);
Reduce duct system acoustics (environmental costs); and
Minimize air balance procedures (commissioning costs).
