AHR Expo Preview

The 2018 AHR Expo (short for International Air-Conditioning, Heating, Refrigerating Exposition) – to be held Jan. 22-24, 2018 at McCormick Place, Chicago, concurrently with ASHRAE’s Winter Conference – is one of the largest HVAC&R trade shows in the world.

Now in its 88^th year, the AHR Expo, co-sponsored by ASHRAE and AHRI, will encompass 2,000+ exhibitors, including many that market natural refrigerant systems. It will feature 100+ seminar and product presentations, including a number relating to natural refrigerants. And it will attract more than 65,000 attendees, including contractors, engineers, facility managers, distributors, OEMs and other HVACR industry professionals.

Here’s a look at what some companies involved with natural refrigerants will be showcasing at the Expo.

Carel, booth 5377

Italian component maker Carel offers a number of products supporting natural refrigerants, such as its EmJ modulating ejector that improves the efficiency of transcritical CO₂ systems. “This solution makes CO₂ efficient in warmer climates,” said Lisa Murray, Carel’s head of sales North America, Refrigerated Retail.

The continuous modulation ensured by the ejector allows the system to “continuously adapt to the typical variations in operating conditions,” said Carel on its website.

The use of modulating ejectors, in concert with Carel’s pRack pR300T compressor rack controller, allows integrated and synchronized management of all the transcritical rack’s components.

Carel will also showcase Heos water-loop system, which can accommodate CO₂ and propane. This includes a controller that manages individual display cases, a DC technology compressor, an electronic expansion valve and dashboards.

Dorin, booth 4649

At AHR Expo this year the Italian-based manufacturer is planning to bring its inaugural compressor for transcritical applications, Series CD500. The CO₂ semi-hermetic compressor is one of the largest compressors on the market for transcritical use.

Sanden, booth 7565

Japan-based company SANDEN will be displaying its SANCO₂, CO₂-based hot water heat pumps, which have recently been introduced to the U.S. market. The units are ETL (Electrical Testing Laboratories) and EPA approved. They are also four times more energy-efficient than electric water heaters, and about two times more than conventional heat pump water heaters – which typically run on either R410a or R134a.

KeepRite, booth 3118

This year the manufacturer will be unveiling new KEP Extended Profile Evaporators. The KEP Extended Profile line features internally enhanced tubing and SmartSpeed technology. They’re also compatible with low-GWP refrigerants, have high-efficiency and high-strength fan guards, ample electrical and header compartments, and are UL certified.

Emerson, booth 5310

At AHRI 2018, St. Louis-based Emerson’s refrigeration and cold chain teams will feature the refrigeration, controls, monitoring and service solutions available through its distribution network and supported by trained contractors for use in grocery retail, convenience stores, foodservice, distribution and transportation applications. The primary areas of focus will be:

• Copeland low- and medium-temperature refrigeration systems, plus compact condensing units for foodservice applications.
• Copeland natural refrigeration systems optimized for grocery and food processing facilities.
• Emerson supervisory control systems engineered to support efficient refrigeration and facility management in grocery, foodservice and other retail applications.
• Emerson ProAct apps, insights and management services that help operators improve results across their enterprises.
• Transformative Wave rooftop unit controls, which help improve energy efficiency
• In-booth Emerson E360 educational sessions exploring IoT in facility management and the latest in energy and refrigerant regulations

 In the cooling category, Emerson won an Innovation Award for its Copeland Scroll two-stage compressor, covering from one to 10 TR. The compressor is a third-generation technology that was redesigned for more performance and reliability in residential and commercial air conditioning systems. The Copeland Scroll offers up to 5% greater full-load and part-load performance.

ebm-papst, booth 2119

Farmington, Conn.-based ebm-papst will be highlighting the following products aimed for the use in the refrigeration market at the AHR Expo:

– BUS-enabled EC fan assemblies for use in display case and bottle cooler applications, which take full advantage of the “Internet of Things” with BUS communication for evaporator and condenser fans.  BUS communication provides control of fan operation and can enhance energy savings and refrigeration performance and limit downtime.  In addition, these fan assemblies are compatible with hydrocarbon refrigerants that are quickly becoming the industry standard.

– Refrigeration Controls. ebm-papst is able to now provide controls for refrigeration equipment. 

– AxiBlade rooftop condenser fans. ebm-papst’s new fan design significantly reduces energy consumption and at the same time lowers operating noise.  The AxiBlade line is backward compatible to the existing AC and EC product line.

– Evaporator fan assemblies. The AxiCool product line up is designed for the needs of walk-in cooler freezers and cold storage room applications. 

– The S1G305 series fan for the most common 12-inch-diameter walk-in cooler and freezer evaporators. The fan assembly is designed for quick installation, and the EC motor makes it eligible local utility company rebates. 

Munters, booth 6900

Texas-based Munters plans to display its DryCool EVR-Focus, a dedicated outdoor air system (DOAS). The DOAS combines desiccant dehumidification with energy recovery; the features new to this design include: a smaller footprint, easier maintenance, a higher dew-point option with greater controls strategy, and upgraded efficiency features
