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.

About the speaker(s)

Toshiaki Hosono


Mr. Hosono holds many responsibilities within brine-ice storage equipment for Ultra Eco-Ice System (Energy and Money Saving System) using CO2 refrigeration. He is in charge of the research of fundamental points such as the amount of appropriate CO2 refrigerant and the behavior of CO2 refrigerant and oil and generation of brine-ice, as well as the research of piping construction for CO2 refrigerant. Hr. Hosono is also responsible for the design and assembly of the evaporation for brine-ice generation and the design and demonstration of brine-ice storage equipment using CO2 refrigeration.
