Workshop 2
Optimization of Direct AC Systems with Low GWP Refrigerants
Fundamentals and Applications
Augustus V/VI (Caesars Palace Las Vegas)
Chair:
Martin Dieryckx, Daikin Europe NV
Sponsor: Refrigeration Committee
In view of the requirement to reduce the climate impact of refrigerants, several refrigerants are proposed for use in direct expansions air-conditioning systems. There are test programs such as AREP and PRAHA to evaluate some of the solutions. The results of these tests do not always give the straight answer that we expect. How should we read these results and what parameters are most important to decide the refrigerant for the specific application. This workshop has the target to give a better insight how the next generation refrigerant can be decided for direct expansion AC equipment.
1 Study on Properties of Low GWP Refrigerants
This study explains the differences in thermo-physical and other properties of alternatives that affect performance of direct (Air cooled) AC system. Thermo-physical cycle, pressure losses, heat transfer and thermal losses are discussed. Reasonable saturation pressure of refrigerant is necessary to avoid poor energy efficiency.
2 Analysis of Test Results on Low GWP Refrigerants
Test results with new refrigerants in actual systems vary considerably leading to initial uncertainty about the relative merits of the new fluids. Factors that influence measured performance as compared to theoretical expectations are presented and their relative impact and sensitivity is discussed.
8:00 AM-9:00 AM

Sitting Around Collecting Dust: Evaluating Industrial Dust Collector Performance
Commercial and Industrial IAQ
Roman III (Caesars Palace Las Vegas)
Chair:
Geoff Crosby, Lydall
Technical Committee: 5.4 Industrial Process Air Cleaning (Air Pollution Control)
ASHRAE Standard 199 was published in June 2016 to evaluate the performance of industrial pulse-cleaned dust collectors. This workshop reviews Standard 199, the research that led to this methodology, and explore actual performance data. This method of test applies to bag, cartridge, or envelope industrial dust collectors that recondition the filter media by using pulses of compressed air to discharge the dust cake from the filter media. Attendees will learn how the test evaluates dust collector performance in terms of energy consumption and particulate emissions.
1 Standard 199: Ashes to Ashes, Dust to Dust?
ASHRAE Standard 199 was published in June 2016 to evaluate the performance of industrial pulse-cleaned dust collectors. The workshop covers development of this standard, and its progress to a new ISO standard. This method of test applies to bag, cartridge, or envelope industrial dust collectors that recondition the filter media by using pulses of compressed air to discharge the dust cake from the filter media. Attendees will learn how the test evaluates dust collector performance in terms of energy consumption and particulate emissions.
2 Dusting Off Some Research: From RP-1284 to Standard 199 Test Results
Research Project 1284 provided foundational research for evaluating dust collector performance. Speakers discuss that research and its conclusions, and how those conclusions were applied to ASHRAE Standard 199. The workshop also looks at some actual test data from tests using Standard 199 to explain results.

Workshop 4
What Is Renewable Energy?
Fundamentals and Applications
Roman II (Caesars Palace Las Vegas)
Chair:
Kevin Brown, P.E., The Linc Group
Technical Committee: 2.8 Building Environmental Impacts and Sustainability
This workshop attempts to define renewable energy from several different perspectives (government, industry, society). Additionally, it reviews real world examples of what qualifies for renewable energy credits according to different jurisdictions around the world.
1 PV Systems Cannot Be Attached to the Grid and Other Renewable Energy Myths
Integration of renewable energy systems with the buildings is a mystery to many. Questions about net metering, batteries, peak savings, renewable energy certificates abound as many consider how to reduce their environmental footprint with renewables. One identified barrier is a relatively low working knowledge of the technologies—both wind and solar. This presentation provides an engineer’s perspective on application of these two renewable energy sources in the building sector. It will also provide information on the benefits and challenges associated with metering, renewable energy certificates, resiliency, and cost-effectiveness.
2 The Role of Biomass in a Renewable Energy Future
Biomass is defined in detail; legally and practically, and reviewed for its role in renewable energy. The abundance of biomass, and its many readily available forms is examined as well as the advantages of its use, particularly for heating and cooling. Options for converting biomass to energy such as methane digesters, wood combustion, trash to energy, and biomass gasification will be provided. The impacts of using biomass instead of fossil energy sources is also explored.
8:00 AM-9:00 AM
Workshop 5
What Should Be in a New Applications Handbook Chapter Covering Semi-Conductor and Nano-Technology Facilities
Fundamentals and Applications
Emperors I (Caesars Palace Las Vegas)
Chair:
Michael Connor, P.E., WSP
Technical Committee: 9.2 Industrial Air Conditioning
CoSponsor: 9.11 Clean Spaces
Currently the ASHRAE Handbook, Applications volume contains chapters that affect the design of components of semi-conductor and nano-technology facilities. There is no chapter currently that pulls all of it together. What is lacking in the other chapters that can be addressed in a high level chapter discussing these facilities?
1 Safety Aspects of Semi-Conductor Facilities
ASHRAE members are being asked in the design of systems to consider the safety aspects of systems. Semi-conductor and Nano-technology facilities are among some of the most dangerous facilities that ASHRAE membership may encounter. Should a new chapter be developed for these facilities and should the methodology for assessing risk and developing mitigating factors be a significant portion of that chapter?
2 Beyond Supply and Exhaust: What Else Should We be Concerned with in Semi-Conductor Facilities?
ASHRAE members are typically concerned with supply and exhaust systems in Semi-conductor facilities. However there are many other areas that can affect the performance of HVAC equipment. Should a Handbook Chapter dedicated specifically to Semi-conductor and Nano-technology facilities be created to address these concerns beyond clean room design and industrial gas cleaning?
9:45 AM-10:45 AM

Key Impacts of ASHRAE Standards on Waterside Construction and Design
Building Operation and Performance
Emperors II (Caesars Palace Las Vegas)
Chair:
James Robert Fields, ASHRAE
Technical Committee: 7.2 HVAC&R Construction & Design Build Technologies
ASHRAE standards have become building codes throughout North America. Contractors and design build engineers are expected to apply standards to construction projects. In the real world of HVAC hydronic system construction, we find a lack of understanding of basic sections. This workshop takes a common sense approach to specific sections of Standard 90.1 and others that have a direct impact on HVAC installation and design. Then approach this from a real world perspective, explaining why they are needed from an energy and health standpoint. This workshop is about understanding a few important sections and why ASHRAE has included them.
1 Key Impacts of ASHRAE Standards on Waterside Construction and Design
Many ASHRAE Standards Have become building codes. Contractors and Design Build Engineers apply these standards to their projects. HVAC Hydronice systems construction often reveals a lack of awareness and understanding of basic sections. This workshop takes a common sense approach to specific sections of 90.1 and others that have a direct impact on Waterside construction and design. The goal is to approach this from a real world perspective explaining why they are needed from an energy and health standpoint.
2 Impact of ASHRAE Standards on Piping Systems
Design build contractors make a lot of decisions and sometimes the decisions they make have far reaching impacts on system performance and energy consumption. This short presentation is informative to attendees.
