The eight roof-mounted units at the Songdo facility provide a nominal cooling capacity of 93.8kW at an evaporating temperature of −5°C.
The manufacturer has adapted its CO2 compressors and GK shell-and-tube gas cooler for marine applications, with optional DNV certification.
The manufacturer analyzed the design for multiple low- and medium-temperature applications using Bitzer’s new Fender simulation tool.
The March installation of the 61.8kW chiller was the manufacturer’s first for its FrigoNatura line.
The lab features a CO2/R290 cascade refrigeration system installed in a Curitiba technical school that simulates a mini-supermarket.
In modeling, the technology increased the COP of a 350,000ft2 cold-storage facility with a transcritical CO2 refrigeration system by up to 17%.
The event, organized by Bitzer and held June 6–7, also featured presentations on a butane high-temperature heat pump and a CO2 chiller system that cools the Large Hadron Collider.
The Innovation of the Year short list features products from Hillphoenix, OLAB, Bitzer and Danfoss.
The Danish manufacturer is ready to meet the European demand for large-scale heat pumps.
The ammonia compressor pack will save Pilgrim’s UK more than £80,000 (US$101,664/ €93,460) annually in energy costs versus its legacy ammonia system.
