ORLANDO, Fla. – It was high fives and congratulations all around as the AHR Expo handed out this year’s Innovation Awards. Gathered in the new technology theatre of the Orange County Convention Center, Orlando, Florida, the Innovation Award winners not only received their plaque, but they waited to find out who among them would be named Product of the Year.

That honor and distinction went to the Danfoss CO2 Adaptive Liquid Management (CALM) Solution.

“It’s a huge honor, not just for me for accepting the awards on behalf of Danfoss, but for all the people in the organization that have contributed to this product,” said Peter Dee, sales and service director — North America, Danfoss. “It is just an honor to be recognized by the industry for this product. This product is unique because it is a combination of all our products coming together with software.”

CALM combines Danfoss’ liquid ejector and adaptive liquid control case controller algorithm to fully utilize the evaporator surface in display cases and cold rooms. This technology provides, without equipment change, up to 10 percent greater energy efficiency in addition to the energy-saving inherent of CO2 refrigeration. The CALM solution works by pulling liquid refrigerant from the suction side and injects it into the evaporator of display cases and cold rooms. Danfoss’ CALM solution aims to assist customers in making the transition to climate-friendly refrigerants while saving energy, maintaining system reliability, and ensuring food safety.


Another tradition of the AHR Expo Innovation Awards is to donate all of the entry fees collected to a local charity outreach. This year, the Orlando Police Athletic League (PAL) received $26,300 in a special presentation during the awards ceremony. Three officers involved with the PAL program were on hand to accept the award. The host of the awards said that this is the highest amount the AHR Expo has awarded in the history of the contest.


Last year’s winner, enVerid’s HVAC Load Reduction® (HLR) module 1000E-M, has been slightly upgraded in 2019 and the indoor model now has an outdoor model as well. According to the company, the HLR 1000-15R is designed for outdoor use, typically on a rooftop. The cabinet is double-walled, insulated, weather-tight, and deployed in horizontal orientation.

We're working on several things from a product standpoint, but the most important thing for us is continuing to expand our offering and presence,” said Udi Meirav, founder and CEO of enVerid. “We continue to make typical generational improvement in the [HLR] system, nothing earth shattering but it does the same thing a little bit better and a little bit more powerful.”
