Tsutomu Saito - Cooperative society ''CO-OP MIRAI''
PDF document
published on 9 February 2016
Using a CO2 refrigeration system case study, Tsutomu Saito highlighted the main reasons to install CO2 technology, including helping to prevent global warming and making energy savings. In its Shintakakura store, CO-OP Mirai expects to see 27% energy savings compared to HFC refrigerants.

Oliver Javerschek - High-efficient integrated CO2-based solutions around the world
PDF document
published on 9 February 2016
Bitzer’s Olivier Javerschek investigated how high efficiency CO2 systems are staying at the forefront of commercial refrigeration technology. Through integrated solutions for low- and medium-temperature loads, as well as air conditioning and heating, CO2 technologies are constantly evolving to meet the demands of differernt ambient regions.

Abel Gnanakumar - CO2 booster system using mixed scroll/ piston compressor technology
PDF document
published on 9 February 2016
This presentation explored the combined use of scroll and semi-hermetic technology to enhance CO2 booster systems. Studies have shown that no special engineering is required to mix the compressor technologies in building a booster pack, with the added benefit that scrolls offer ease of modulation and ensure that the overall system is more cost-effective.

Tadao Sekiguchi - High efficiency integrated parallel compressor for CO2 systems
PDF document
published on 9 February 2016
Using a case study from the Schaufler Academy in Southern Germany, CAREL’s Tadao Sekiguchi deduced that high efficiency integrated parallel compressors for CO2 systems increase their COPs dramatically, citing third-generation CO2 booster systems as “the future” in light of the revised f-Gas Regulation.

Toshiaki Hosono - Energy efficiency of brine-ice thermal storage system using a new type of CO2 refrigeration unit
PDF document
published on 9 February 2016
Yamato’s Toshiaki Hosono presented case study data on the performance of the Ultra Eco-Ice system with the new CO2 pressure adjust control system, first introduced to the market in 2015. Yamato has found that brine ice thermal storage-equipped systems differ from standard direct expansion CO2 system in three ways: lower energy consumption, higher COP and reduced initial costs via downsizing of the system.
