Available in PDF, EPUB and Kindle. Book excerpt: 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.Learning ObjectiveAt the conclusion of this course, the reader will understand:1.

Book excerpt: This Strategy Guideline discusses the benefits and challenges of using a compact air distribution system to handle the reduced loads and reduced air volume needed to condition the space within an energy efficient home. Traditional systems sized by 'rule of thumb' (i.e., 1 ton of cooling per 400 ft2 of floor space) that 'wash' the exterior walls with conditioned air from floor registers cannotprovide appropriate air mixing and moisture removal in low-load homes. A compact air distribution system locates the HVAC equipment centrally with shorter ducts run to interior walls, and ceiling supply outlets throw the air toward the exterior walls along the ceiling plane; alternatively, high sidewall supply outlets throw the air toward the exterior walls. Potential drawbacks includeresistance from installing contractors or code officials who are unfamiliar with compact air distribution systems, as well as a lack of availability of low-cost high sidewall or ceiling supply outlets to meet the low air volumes with good throw characteristics. The decision criteria for a compact air distribution system must be determined early in the whole-house design process, considering bothsupply and return air design. However, careful installation of a compact air distribution system can result in lower material costs from smaller equipment, shorter duct runs, and fewer outlets; increased installation efficiencies, including ease of fitting the system into conditioned space; lower loads on a better balanced HVAC system, and overall improved energy efficiency of the home.

Available in PDF, EPUB and Kindle. Book excerpt: In this book, various aspects of heating, ventilation, and air-conditioning (HVAC) systems are investigated. HVAC systems are milestones of building mechanical systems that provide thermal comfort for occupants accompanied with indoor air quality. HVAC systems can be classified into central and local systems according to multiple zones, location, and distribution. Primary HVAC equipment includes heating equipment, ventilation equipment, and cooling or air-conditioning equipment. Central HVAC systems are located away from buildings in a central equipment room and deliver the conditioned air by a delivery ductwork system. Central HVAC systems contain all-air, air-water, or all-water systems. Two systems should be considered as central such as heating and cooling panels and water-source heat pumps.

Book excerpt: Substantial commercial building energy savings have been achieved by improving the performance of the HVAC distribution system. The energy savings result from distribution system design improvements, advanced control capabilities, and use of variable-speed motors. Yet, much of the commercial building stock remains equipped with inefficient systems. Contributing to this is the absence of a definition for distribution system efficiency as well as the analysis methods for quantifying performance. This research investigates the application of performance indices to assess design advancements in commercial building thermal distribution systems. The index definitions are based on a first and second law of thermodynamics analysis of the system. The second law or availability analysis enables the determination of the true efficiency of the system. Availability analysis is a convenient way to make system efficiency comparisons since performance is evaluated relative to an ideal process. A TRNSYS simulation model is developed to analyze the performance of two distribution system types, a constant air volume system and a variable air volume system, that serve one floor of a large office building. Performance indices are calculated using the simulation results to compare the performance of the two systems types in several locations. Changes in index values are compared to changes in plant energy, costs, and carbon emissions to explore the ability of the indices to estimate these quantities.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the results of the first phase of a multiyear research project. The project's goal is to investigate ways to improve the efficiency of air-distribution systems in detached, single-family residences in California. First-year efforts included: A survey of heating, ventilating, and air conditioning (HVAC) contractors in California. A 31-house field study of distribution-system performance based on diagnostic measurements. Development of an integrated air-flow and thermal-simulation tool for investigating residential air-distribution system performance. Highlights of the field results include the following: Building envelopes for houses built after 1979 appear to be approximately 30% tighter. Duct-system tightness showed no apparent improvement in post-1979 houses. Distribution-fan operation added an average of 0.45 air changes per hour (ACH) to the average measured rate of 0.24 ACH. The simulation tool developed is based on DOE-2 for the thermal simulations and on MOVECOMP, an air-flow network simulation model, for the duct/house leakage and flow interactions. The first complete set of simulations performed (for a ranch house in Sacramento) indicated that the overall heating-season efficiency of the duct systems was approximately 65% to 70% and that the overall cooling-season efficiency was between 60% and 75%. The wide range in cooling-season efficiency reflects the difference between systems with attic return ducts and those with crawl-space return ducts, the former being less efficient. The simulations also indicated that the building envelope's UA-value, a measurement of thermoconductivity, did not have a significant impact on the overall efficiency of the air-distribution system.
