2009 AHR EXPO, January 26-28 Chicago's McCormick Place

AHR EXPO Still Strong

By Bill Lydon - Contributing Editor
The 61st AHR EXPO was among its biggest and best events of all-time with approximately 35,000 attendees and more than 19,000 exhibitor personnel for a total of 54,000.  The show featured over 1,900 exhibiting companies and now ranks as the second largest AHR EXPO, just behind the 2006 Chicago Show, in terms of number of exhibiting companies (1,911). The 2009 event also ranks as the fourth largest AHR EXPO of all-time in terms of square footage (396,048 net square feet). Since 1930, the AHR EXPO (www.ahrexpo.com) continues to be the largest Heating Ventilation, Air Conditioning, and Refrigeration (HVAC/R) exposition and is endorsed by HVAC/R industry associations. The Exposition is co-sponsored by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the Air-Conditioning, Heating and Refrigeration Institute (AHRI). The Heating, Refrigeration and Air-Conditioning Institute of Canada (HRAI) is an honorary sponsor. ASHRAE's winter meeting is also held concurrently with the AHR EXPO. The AHR EXPO’s is endorsed by thirty-one organizations.
Green Focus
A number of ‘green’ products were displayed - building on the ‘green’ focus of last year’s show in New York.  There were several green seminars and sessions offered to attendees including:
  • The U.S. Environmental Protection Agency’s (EPA) Energy Star Program hosted an information booth and conducted an educational session.
  • The Partnership for Environmental Leadership's HVAC Mobile Green Classroom was on the AHR EXPO Show Floor. 
  • The U.S. Green Building Council (USGBC) presented a full-day LEED educational program.
  • The Green Mechanical Council (GMC) provided two free educational programs.
  • The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) offered several seminars on a variety of important ‘green’ topics. 
Overall Impressions
Embedded Intelligence
More intelligence is moving into smaller field devices with examples from MAMAC, Cypress Envirosystems, and Control Solutions covered in this article.
WEB Servers Everywhere
Web servers are being put in small and large devices.  Plexus came back to AHR after a few years with their Web based automation.  Also, Open General, an Australian company, exhibited their Web-based automation system for the first time at AHR. The company’s system is built on the Microsoft.net architecture incorporating SQL Server and BACnet.
Wireless is pervasive and has been adopted by a wide range of users because of the simple economic decision based on installation savings. The standards issue that is impeding adoption of wireless in the industrial automation market does not appear to be an issue in the building automation market.  Certainly ZigBee looks to be on track to eventually be the major standard.
Tridium remains a phenomenon that just keeps getting larger. Tridium continues to grow as an independent business entity of Honeywell International Inc.   Tridium had two large booths at different locations on the AHR trade show floor - the Vykon booth for the system integrator market and the Tridium booth for OEM.   More information follows in this article.
CISCO’s announcement of the acquisition of Richard-Zeta on the second day of the show certainly created buzz. CISCO’s move in the Building Automation Industry has the potential to ignite the biggest structural change in the industry since DDC.  More follows in this article.
Variable Speed Drives
There was great interest in the offerings of variable speed drive manufacturers focused on reducing physical size, increasing efficiency and lowering electrical noise that will be covered in a separate article.

Products of Interest 
Tridium continues to grow as an independent business entity of Honeywell International Inc.   Tridium had two large booths at different locations on the AHR trade show floor. The Vykon booth for the system integrator market and the Tridium booth for OEM. Tridium was demonstrating its new NiagaraAX and Sedona Framework applications for Building and Residential Automation, Security, Video Integration and Energy Management.
New JACE-202
The company previewed its new JACE-202 XPR, Java Application Control Engines (JACE®) that is a wireless and wired embedded controller/server platform designed for remote monitoring and control applications. The JACE-200 is a member of the Vykon suite of Java-based controller/server products, software applications and tools, and incorporates the NiagaraAX Framework. The JACE-200 can be expanded with optional 16 and 34 point I/O modules. The base unit includes two Ethernet ports, one RS-232 port, and one RS-485 port. Web User Interface and Niagara Connectivity are included along with an oBIX Client/Server driver.
Niagara Video
Niagara Video enables the integration of video with environmental control, intrusion detection, access control, lighting and energy management to add more value in systems.  Tridium showed an example of an HVAC low temperature alarm occurring and the system directing a camera to view the area of where the alarm originated. Personnel review the video to find a leak occurring in the ceiling and remotely shutting down the HVAC system before calling for emergency repair. As I watched the demonstration, I thought of how we relied on intercom systems in early building automation systems to listen for squealing belts, etc. in equipment rooms. www.tridium.com

BACnet Lighting Control Panels
Cristal Controls claims to have the first and only BACnet IP networked lighting control panels. Crtisal also supports BACnet MSTP.  www.cristalcontrols.com
Enocean LONMARK Alliance
LONMARK announced a collaborative agreement with the EnOcean® Alliance, a consortium of more than 60 companies working to promote EnOcean self-powered, wireless technology as an interoperable wireless standard. The partnership will provide a platform for bringing LONMARK's open, interoperable device-level protocol for wired and unwired networks together with EnOcean's RF end-device solution for low/no-power devices.
EnOcean's technology requires no battery maintenance and is designed to work with established, interoperable network technologies. The differentiator that sets EnOcean above other, wireless technologies is the use of sub-gigahertz frequencies: 868 MHz in Europe and the Middle East, and 315 MHz in the USA and the Far East. These frequencies are in contrast to wireless systems nestled in the 2.45 GHz band (i.e. Bluetooth). The lower, more optimal frequencies exhibit lower attenuation through walls and achieve about twice the range for the same transmitting power.
LONMARK also presented Thermokon with the Infrastructure Product of the Year award in honor of its Easysens SRC65-FTT Receiver, a radio receiver using EnOcean’s core technology combined with a LonWorks interface. The receiver directly converts all radio telegrams received to LonWorks standard network variables (SNVT), and offers predefined objects, such as various sensors and switches, with the corresponding output variables (SNVT) for communication in a LonWorks system.  
Contemporary Controls Expands BACnet Offerings

Cypress Envirosystems Wireless Pneumatic Thermostat
Cypress Envirosystems demonstrated their new Wireless Pneumatic Thermostat that provides a quick and efficient way to retrofit buildings that have pneumatic controls. Cypress Envirosystems’s claims the Wireless Pneumatic Thermostat (WPT) can be installed in less than 20 minutes by replacing the old pneumatic.   The hybrid thermostat has an in-built Pneumatic Thermostat that control valves and dampers using the existing pneumatic air pipes.   The Wireless Pneumatic Thermostat (WPT) provides local digital readout, night setback, zone control, and occupancy override.   The WPT can be integrated with existing building automation systems via BACnet/IP using Cypress Envirosystems WPT BACnet Server.
Cypress Envirosystems claims that for a typical use of 4 setpoint changes per day and 30 minute update interval, estimated battery life is approximately 2 years. Less frequent setpoint changes and longer update intervals can extend the battery life to 4 years.
The WPT is directly compatible with the majority of legacy pneumatic thermostats from Honeywell, Johnson Controls, Robertshaw, and Siemens.
The company also demonstrated their Wireless Steam Trap Monitor (WSTM) and Wireless Gauge Reader (WGR) products.
MAMAC IP Sensor Appliance
MAMAC demonstrated their new Maverick IP Sensor Appliance that incorporates a web server, analog/digital inputs and relay outputs.  MAMAC has been a sensor company until introducing this control and information offering. The Maverick IP Sensor Appliance has an embedded lean TCP-IP stack including HTTP, SMTP, DHCP, DNS, FTP, and ARP. The Maverick also has XML embedded with formatted input & output data enabling the Maverick to communicate directly with any IT system which has an XML parser. Similarly, any simple JavaScript can be used to communicate and acquire HTML data. The Maverick can send email alerts to two different email addresses and datalog up to 2048 samples for each input.
The Maverick is available in two I/O versions. The first version has 8 analog or digital inputs and the second has 4 analog or digital inputs and 4 relay outputs. The analog inputs can be specified to be voltage (0-5 or 0-10 VDC) or current inputs. The output relays are rated for 5 Amps @ 250 VAC and can be used for pilot duty or light load switching directly.
Control Solutions BACnet WEB Server
Control Solutions demonstrated their new BACnet Web server designed to add server functionality to MS/TP devices. The device has a BACnet IP client and server and BACnet MS/TP client and server (master and slave). The unit will periodically poll MS/TP devices, or devices may directly write to local objects in the server. COV (Change of Value) subscriptions are supported. This is not a router; this is an object server with two ports (Ethernet and RS485) for accessing its objects.
The company’s goal is to provide a simple and cost effective facility management and remote monitoring solution suitable for use in small sites. The server includes data logging, time & date scheduling, and template or rule based alarm processing with email notification and/or I/O activation in response to events. Data logging simply records the contents of registers on a user specified schedule. Event logging keeps a record of alarm events. Scheduling causes register values to be set according to a schedule. The resulting register manipulation may generate network communication with remote devices, control local I/O, or change setpoints.
