AHR Expo Preview

Co-sponsored by the American Society of Heating, R efrigerating and Air-Conditioning Engineers (ASHRAE) and the Air Conditioning, Heating and Refrigeration Institute (AHRI), the 2024 International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo) is expected to draw more than 50,000 attendees to Chicago, Ill., in January. (The annual show is never closer to the Canadian border than when it rotates to Chicago’s McCormick Place, so it wouldn’t be surprising if many of those attendees were to arrive from parts north!)

Over three days, from Jan. 22 to 24, AHR Expo will showcase more than 1,600 exhibiting heating, ventilation, air conditioning and refrigeration (HVACR) prod- uct manufacturers, along with more than 370 expert speakers through more than 110 free seminars, panel discussions and more than 145 new product and technology theatre presentations, focusing on new trends, regulations, practices and industry forecasts.

“The education program has grown into a true complementary asset to the show floor experience,” says Mark Stevens, show manager. “It will offer discussions about real problems that are shared across the industry. By inviting our associations and community leaders to the table, we can spark important conversations that lead to smarter decision-making.”

The following pages preview just a few of the educational highlights of this year’s AHR Expo that may prove especially relevant to consulting engineers who work with HVACR systems. Canadian Consulting Engineer will be at the show too, so you may see us at some of these!

Educational Highlights

Monday, Jan. 22

10:30 a.m.

Thermal Energy Storage: Current Technologies and Innovations

In this panel discussion, attendees will learn about innovations in thermal energy storage. The presentation will cover rooftop packaged units, chillers and campus-wide tanks, as well as economic and carbon-reduction benefits to users and to the grid.

(Location: S403a)

1 p.m.

Fundamentals of Adiabatic Heat Rejection

This entry-level session will discuss how to compare various heat-rejection systems, how to determine when adiabatic coolers and condensers are right for a specific project, the different types of adiabatic units available and requirements for code compliance. (Location: S401a) effective ventilation systems, air filtration techniques and humidity control, and discuss the pivotal role of source control in minimizing pollutants. (Location: S403b)

1 p.m.

2:30 p.m. and 4 p.m.

Fan and System Curves with Fan Energy Index (FEI)

Tuesday, Jan. 23

8 a.m.

Revolutionary Energy Management: Rethinking the Paradigm

Necessity of

Filtration

on Open Cooling Systems

This is a one-hour entry-level course on the basics of HVAC water filtration. The course will discuss overall benefits in detail (including potential energy savings), system efficiency, various types of filtration typical to HVAC, basic applications and sizing. (Location: S401d)

1:30 p.m.

This two-part session will examine how fan and system curves are derived and interpreted, how static p ressure and velocity pressure change as air moves through a system, how pressure loss is calculated and how the fan energy index (FEI) efficiency metric works. (Location: S404d)

3 p.m.

ACG Building Systems

Commissioning Guideline Overview

This session suggests energy consumption, decarbonization and comfort could be revolutionized by preloading buildings with heating or cooling as a ‘reservoir’ to be tapped as needed, leveraging the Internet of Things (IoT) and artificial intelligence (AI). (Location: S402b)

9 a.m.

The Engineer’s & Integrator’s Role in Creating Cyber Harmony

Indoor Air

Quality: Understanding the Link Between Ventilation, Health & Industry Dynamics

This intermediate session will explore strategies to address indoor air quality (IAQ) challenges, including

This session will present best practices for executing the ASHRAE Standard 202 process, with details for commissioning specific types of building systems while overcoming common challenges encountered in both design and field settings. (Location: S402a)

This presentation will introduce the concept of ‘cyber harmony’ and its relevance to the roles of consulting engineers and systems integrators, delving into hardware and software that must be integrated into designs to ensure the security of their deployments. (Location: S401bc)

11 a.m.

Trending and Driving Forces of Change for Smarter Buildings

In this session, attendees will learn how the Smart Building Academy has made a difference as a driving force in ASHRAE and joint working groups and how industry thinkers continue to change the building automation systems (BAS) business.

(Location: S401bc)

1 p.m.

Heat Pumps, Electrification and the Grid

This panel will discuss deploying heat pumps in retrofits while addressing major barriers to electrification: how to avoid costly upgrades to a building ’s electrical infrastructure; and how to prevent stress on the grid from added load during peak demand. (Location: E350)

3 p.m.

Application, Installation and Maintenance of Life-Safety Dampers

Fire and smoke dampers are integral to fire protection in commercial and industrial buildings, restricting the spread of flame and smoke. This session will address the finer points of these devices’ application, installation and maintenance.

(Location: S404d)

Wednesday, Jan. 24

9 a.m.

Air-Curtain Technology: Theory, Operation and Applications

This presentation will cover all facets of air-curtain technology, which is installed at a building’s entrance to minimize the cross-migration of warm and cold air from buoy ancy pressures and wind, while repelling airborne dust, dirt, fumes, odours and insects.

(Location: S404d)

10:30 a.m.

A Hybrid Solution to Heating, Cooling and Ventilating Schools

As centralized heating and air systems cannot adequately ventilate individual rooms in large school buildings, this presentation will cover decentralized strategies, the measurement of proper ventilation and the importance of indoor air quality (IAQ) to students. (Location: S404d)

12:30 p.m.

The Decarbonization Countdown: What’s in Store for Commercial HVAC Systems

This 60-minute session will highlight the top sustainability challenges on the horizon for the commercial HVAC industry and provide guidance for its professionals as they join the decarbonization movement. (Location: S404bc)

1 p.m.
