Hillphoenix installs first CO2 ejector

USA: Hillphoenix has installed the first CO2 booster system with ejector technology in North America at a Sprouts Farmers Market in Woodstock, Georgia.

In warmer climates, like Georgia, a Hillphoenix CO2 Second Nature system using Danfoss ejector refrigeration technology combined with parallel compression is said to boost efficiencies and yield substantial savings.

Lab testing conducted by Hillphoenix is said to have revealed that while parallel compression alone increased the peak energy efficiency of a standard booster system by 8%, using a Danfoss ejector configured as a gas ejector with parallel compression in the same test system increased peak savings to 11.3% when operated under non-optimised conditions.

“When the system has been optimised – as revealed in tests carried out by our Advansor operation in Europe, savings for parallel compression alone and parallel compression combined with gas ejector technology can achieve peak energy reductions of 15% and 23% respectively,” said Jeff Newel, Hillphoenix director of refrigeration systems R&D.

Headquartered in Phoenix, Arizona, Sprouts Farmers Market operates more than 260 stores in 15 US states.

The Danfoss ejectors are said to be the first to be used in the US
