Company: Daikin Applied (www.daikinapplied.com; 2017 AHR Expo booth No. C2509)

Innovation: Pathfinder® Air-cooled Screw Chillers with Variable Volume Ratio (VVR) Technology

The new Daikin Pathfinder AWV air-cooled screw chiller features unique variable volume ratio (VVR) technology which allows the chiller’s compressor to adjust its own internal compression ratio as water and air temperatures fluctuate. With VVR technology, its compressor senses the amount of lift needed and adjusts the compression ratio automatically to provide optimal efficiency under any operating condition, equating to reduced energy use, cost of ownership, and carbon footprint. The Daikin Pathfinder AWV air-cooled screw chiller also features VVR slides that operate on the discharge side of the screw to control the refrigerant compression ratio without altering the per-stroke refrigerant volume, unlike typical capacity control slide valves. Variable frequency drives (VFDs) are used in conjunction with the VVR slides to control motor speed, and subsequently compressor capacity. This results in superior performance under Air-Conditioning, Heating, and Refrigeration Institute (AHRI)-standard conditions, and in real-world scenarios in which air and water temperatures can fluctuate greatly.


Company: Carrier (carrier.com/commercial; 2017 AHR Expo booth No. C1510)

Innovation: Dual Stage Relief Economizer (DSRE)

Carrier’s Dual Stage Relief Economizer (DSRE) for light commercial rooftop units combines a traditional economizer with a means of relieving building pressure without the use of a power-consuming device. DSRE uniquely combines an air economizer with two non-powered pressure relief stages, facilitating the relief of pressure during normal ventilation operation and during economizer free cooling. In many applications, DSRE also eliminates the need for a powered exhaust or a separate pressure relief system, thus reducing both installation costs and building energy consumption. In addition to the relief capability, DSRE allows customers to minimize electrical feeds and breakers for installation, and to lower their initial first cost by enabling use of a smaller electrical feed and breaker. According to a recent Carrier energy model analysis, a typical 10-ton DSRE unit can achieve between $189 and $389 in annual savings (based on $0.12 kWh and between 1,200-2,400 hours of economizer operation).


Company: Noritz America (www.noritz.com; 2017 AHR Expo booth No. C5917)

Innovation: Noritz Combination Boiler

The Noritz Combination Boiler delivers hot water for both plumbing and hydronic residential heating applications, while managing the switch between uses without a perceivable difference in performance. With 95 percent annual fuel utilization efficiency (AFUE), it is Energy Star-rated to deliver maximum operational cost savings to homeowners. The Noritz Combination Boiler’s compact, 90-pound package delivers up to 9.2 gallons per minute of domestic hot water — nearly twice the flow of comparable units. A unique flow control valve also facilitates maximum domestic hot water flow rate at stable temperatures and regardless of incoming water temperature. The boiler’s external and booster pump drive terminals (up to 2 amps) do not require a relay, and its integrated condensing technology lowers exhaust temperatures to a level at which stainless steel venting material is no longer required.


Company: Nortec Humidity (www.humidity.com; 2017 AHR Expo booth No. C4706)

Innovation: Nortec GS Series - CS Model (Nortec GS CS) Humidifier

A gas-fired isothermal humidifier producing hygienic and atmospheric steam, the Nortec GS Series CS Model Humidifier fulfills a wide range of humidification requirements for indoor environments. Direct building management integration allows the GS CS humidifier to deliver necessary steam quantities both inside duct systems and directly into a space, thus more quickly elevating indoor humidity conditions to required set points. Its unique gas-fired operation — believed to be the first to employ condensing technology to facilitate high-efficiency performance — is powered with either natural gas or propane, allowing for flexible and economical function. Delivering more than 93 percent total efficiency, the GS CS humidifier is also one of the first in the industry to employ a secondary heat exchanger to pre-heat water before entering the tank, while subsequently cooling down combustion exhaust gases. The result is a reduction of exhaust gas temperatures by more than 50 percent (when compared to the current market standard-efficiency of 80 percent), thus allowing for flexibility in venting options (both BH and CPVC). A low-emissions (NX) version of the GS CS humidifier is also available, offering further reduced efficiency (>88 percent), and with low NOx emissions of approximately 7 ppm (falling within SCAQMD emissions standards for gas-fired humidifiers).

Innovation: SmartPlug Smart Hot Water Recirculation Control

The SmartPlug Smart Hot Water Recirculation Control from Taco allows for easy installation onto existing domestic hot water recirculation pump systems to more efficiently manage on-demand hot water delivery. The plug-in 115-volt control features technology to learn and record a homeowner’s hot water usage pattern, and employ the resulting data to operate a home’s hot water recirculation pump precisely when hot water is typically required. While hot water recirculation pumps typically run continuously or are controlled with an aquastat or timer, SmartPlug provides fully automatic and self-adjusting pump operation — only when hot water is desired. Usage patterns are monitored and recorded on a daily and weekly basis, with the SmartPlug system regularly refreshing data and adjusting any changes to hot water usage patterns. The result is a significant increase in water heater operational efficiency, promoting a simple yet notable way to save on residential energy costs.


Company: Danfoss (www.danfoss.us; 2017 AHR Expo booth No. C4506)

Innovation: Danfoss CTM (Electrical Controlled Transcritical Multi Ejector)

The Danfoss CTM is an electrically controlled multi-ejector designed specifically for the warm climate operation of transcritical CO2 systems in food retail applications. Capable of recovering energy while controlling the high pressure of the transcritical application, the CTM ejector delivers value to the application through significant (20 percent or greater) improvements in energy efficiency. This is achieved by employing energy recovered from the gas cooler and transferring it to increase the pressure of gas being compressed by parallel compressors, thus reducing overall compressor load. As one of the first commercially viable solutions engineered to overcome energy penalties associated with operating transcritical CO2 systems in high ambient temperatures, the CTM ejector also eliminates the need for redundant, cascade refrigeration systems. In cooler and more temperate climates, it can deliver even further energy saving benefits, with ejectors that create a low pressure at high velocities to optimize operational efficiency in a wide range of load conditions.
