Download or read book Performance and Optimization of an Underfloor Air Distribution System in an Educational Building in a Hot and Humid Climate written by Vasiliy Khmelenko and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Today there is a proliferation of different HVAC system configurations. Design and performance of each HVAC system are dependent on climate and the intended use of the building. Energy recovery ventilation is becoming more common in new buildings and is one of the more popular retrofit options in hot and humid climates. Currently there is a lack of optimization strategies that involve the underfloor air systems combined with Energy Recovery Ventilation (ERV) especially in hot and humid climate. This thesis examines the performance and optimization of underfloor air distribution systems (UFAD) in hot and humid climates. This thesis also compares the UFAD system performance to a typical overhead air handler unit (AHU) system found in Texas. The performance comparison is done with EnergyPlus modeling software. Separate sets of models are created to examine performance of at different operational parameters. The minimum air flow rates are modeled at 0.1 cfm/ft2, 0.2 cfm/ft2, 0.3 cfm/ft2, 0.4 cfm/ft2 for both UFAD and overhead (OH) systems. The supply air temperatures were modeled at 55°F, 60°F, and 63°F. Outside air strategies include simple economizer, energy recovery ventilation (ERV), as well as a combination of both economizer and ERV. The study found that at low minimum (0.1 cfm/ft2) flow rates an overhead system will slightly outperform a UFAD system (OH 2.6% cheaper to operate than UFAD) while at 0.3 cfm/ft2 a UFAD system is more efficient (UFAD 14.8% cheaper to operate). The outside air strategies have the same energy savings effect on both systems. The UFAD system has a higher peak cooling load and a lower peak heating load compared to the overhead system. This thesis also covers the stratification and supply air temperature measurements within two offices inside the Mitchell Physics building, located on the Texas A&M campus. The stratification measurements showed that on average the stratification was lower than expected for such systems with office 411 having average stratification of 1.8°F and office 423 average stratification of 1.5°F. Temperature measurements at the diffuser level showed some reheat, especially during unoccupied periods such as early mornings, late evenings and weekends, even when the outside temperature was above the interior thermostat set point. System level total supply air flow rate showed little variation with a minimum of 0.47 cfm/ft2 and a maximum of 0.59 cfm/ft2. The analysis of energy recovery wheel operation concluded that the low exhaust air flow of only 0.2 of the outside air is responsible for the low temperature difference observed in the outside air stream through the ERV.

Download or read book Underfloor Air Distribution A Comprehensive Guide to Modern HVAC Systems written by Charles Nehme and published by Charles Nehme. This book was released on with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing demand for energy-efficient, sustainable, and flexible building systems has reshaped how we design and operate modern workspaces. As a crucial component of contemporary HVAC systems, Underfloor Air Distribution (UFAD) technology offers an innovative approach to air delivery that can significantly enhance both occupant comfort and energy efficiency. This book aims to provide a comprehensive guide for engineers, architects, facility managers, and professionals involved in the design, installation, and operation of UFAD systems. Over the past few decades, the evolution of building technologies has prompted a shift away from traditional overhead air distribution systems. UFAD systems, with their ability to deliver conditioned air directly from the floor, are proving to be particularly effective in open-plan offices, data centers, and spaces requiring adaptive layouts. However, as with any system, the success of a UFAD system hinges on a thorough understanding of its design principles, proper installation, and ongoing maintenance. This book was born out of the need for a clear, structured resource that can guide professionals through the complexities of UFAD—from the fundamental science behind air distribution to the nuances of real-world system implementation. Each chapter builds upon the last, starting with an introduction to UFAD and gradually delving into more detailed aspects like airflow dynamics, commissioning, and sustainability. While UFAD offers numerous benefits, such as increased energy efficiency, improved thermal comfort, and design flexibility, these advantages are realized only when the system is designed and maintained with precision. Throughout this book, we will explore not only the technical aspects of UFAD systems but also practical insights and lessons learned from successful projects. I hope that this book serves as a valuable resource for professionals at all levels—whether you are considering UFAD for a new construction project or seeking ways to optimize an existing system. By understanding both the opportunities and challenges that UFAD presents, you can leverage this technology to create more comfortable, energy-efficient, and adaptable environments. Thank you for embarking on this journey into the world of UFAD. I am confident that, together, we can push the boundaries of what is possible in building design and air distribution.
