Ultra Eco-Ice System - Innovative solution for Japanese supermarkets

For the supermarkets with total floor space of about 3,000 m², the major scale of Japanese retail food stores, the energy consumption is 3 times of general office buildings. For these supermarkets, the usage of the refrigerants (HFCs), which are non-Ozone layer destruction refrigerant, but high GWP, is increasing. Therefore, due to the phase out HCFCs, a new refrigerant and a new system are needed. YAMATO CO. Ltd., then, introduces a new system that reduces TEWI. This system is called “Ultra Eco-Ice System”, the thermal source equipments for refrigeration equipment and air-conditioner equipment are unified, and accumulate the energy with low-temperature ice (brine-ice) during nighttime and melt them during daytime, then use the cold energy.
