Tesco recently opened its 97th store in China, yet this is the first to feature a CO2 refrigeration system. The 8635-m² supermarket includes a fresh area of 2000 m² and is located in the Cloud Nine Shopping Mall in the Minhang district of Shanghai. The store is the first in China to adopt a CO2 refrigeration system. According to Tesco, the Shanghai store uses 25% less energy than standard store designs.
Designed, installed and commissioned by Shanghai Fute Refrigeration & Electrical Engineering Co, Ltd., the system is a cascade CO2/R404A one, with a low-temperature system capacity of about 60 kW at -33°C, and a medium-temperature system capacity of about 260 kW at -9°C. The exhaust heat from the refrigeration system is recovered and reused to meet the store’s hot water needs. The use of low outdoor temperatures in winter and in transitional periods will generate considerable energy savings.
