Commercial Air Conditioning
Innovative technologies on show at AHR Expo 2020
CCN CHECKS OUT the latest innovations on show at AHR Expo 2020, one of the industry’s biggest international trade shows.
A major theme at the international event, which was held last month in Orlando, was en- ergy efficiency and technologies aimed at reduc- ing our impact on the environment.
One innovation that generated a lot of interest was Dual Path Technology which has been devel- oped by TORO Water Air Thermal Technologies (TORO WATT), a Canadian-based company.
The company’s CEO, Tiger Aster, said the air conditioning technology reduces energy con- sumption by up to 70%.
“Humans are great at sensing temperature and climate conditions. If you’re traveling in the desert in California, for example, which is an ex- tremely dry area of the planet, you know that at
midday it’s hot. It is different to travelling in the Florida Everglades where the humidity is routinely in the 90% range,” he explained.
“While humans are great at knowing the dif- ference in those temperature feelings, air condi- tioning systems traditionally are terrible at sens- ing the difference.”
However a TORO WATT air conditioner senses both the temperature and the humidity level sep- arately and conditions the air for optimal comfort.
Darshi Dhaliwal, CTO and inno- vator of Dual Path Technology, said in a dry atmosphere where there is very little humidity, a traditional air conditioner is still running its dehu- midifier at full blast and is consum- ing all the energy that the system thinks it requires.
“The TORO WATT air conditioner
is able to decide which technology, temperature reduction or dehumidi-
fying, is needed and in what amount. Along with the dual sensing technology, TORO WATT air conditioners also have a patent pending process of recycling condensate and an advanced control panel for maximum customization and efficien- cy,” Dhaliwal said.
REBEL ROOFTOPS
While at AHR Expo, Daikin presented the Rebel Applied rooftop heating and cooling system.
Rebel Applied is the only packaged system to meet ASHRAE’s latest standard for performance in airflow design. Ideal for building retrofits due to its compact and customizable design, Rebel Applied delivers superior comfort, indoor air quality and energy savings, according to Mike Schwartz, CEO of Daikin Applied Americas.
“We believe that quality design needs quality construction to deliver ultimate value,” he said. “So, we opened a new manufacturing facility in southern Minnesota dedicated to the production of Rebel Applied. With advanced fabrication and
automation technologies, we can tailor the build to meet specific customer needs, optimize production and deliver products that will perform at the highest levels.” The rooftop system’s efficient footprint is up to 37 per cent shorter in length and 30 per cent lighter than legacy rooftop units.
It is highly configurable as well; con- tractors can add or remove sections to adjust the length of the unit to fit on old or existing roof curb, saving time
and expense for facility updates and upgrades. Along with Rebel Applied, Daikin previewed two new ultra-high-efficiency chillers at the exhibition – the Magnitude Magnetic Bearing Centrifugal Chiller and Aptitude Oil Bearing Centrifugal Chiller.
Both chillers feature the smallest footprints in the industry compared to equipment with the same cooling capacity utilizing the ultra-low GWP, R1233zd refrigerant, making them ideal for retrofits where real estate is limited or at a premium cost.
The Magnitude chiller builds on Daikin’s lat- est magnetic bearing technology, which elimi- nates oil, seals, gears and wear surfaces for long- er machine life. This allows the equipment to run at peak levels, up to 40 per cent more efficient than standard centrifugal chillers. The Magni- tude can perform at full load efficiencies as low as 0.49 kilowatts per ton (kW/ton) with part load values as low as 0.29 kW/ton. Both chillers will be available later this year. ✺
