Hanshoku - CO₂ Refrigeration System Case Study (in Japanese)

Hanshoku, a Japanese retailer with its head office in Osaka and 75 supermarket (SM) stores in Japan, represented by Ryo Kitamura, sees CO₂ refrigeration systems and government subsidies as a perfect opportunity to convert its existing R22 systems while doing the right thing for environment. This is in line with company’s CSR (corporate social responsibility) policy. In December 2014, the company will open a brand new 2,200m2 supermarket in Osaka. The Hanshoku Oasis SM is equipped with four 20HP, four 15HP and one 10HP CO₂ condensing unit installed on the roof of the SM. Energy efficiency is expected to improve by 12% in comparison with same class of SM equipped with R410A. Annual emissions of CO₂ are also estimated to decrease by 344.5 tonnes of CO₂-eq.
