PartagerDalian builds China’s first CO2/NH3 cascade cold storage logistics base
China is building the largest cold storage logistics base for aquatic products in Dalian, Northeast China. The 200 000-tonne, RMB 1 billion (roughly 128 million €) cold store is said to be the first large-scale cold storage logistics base adopting a CO2/NH3 cascade refrigeration system in China.

Dalian Zhangzidao Fishery Group and Tokyo-based Chuo Gyorui Co Ltd and Hohsui Corp. from Japan are building the facility.
The first of four new cold stores comprises 12 freezing rooms with temperatures ranging from -25°C to -20°C and an ultralow temperature (-60°C) cold room with a capacity of 500 tons. CO2 is used as the coolant inside the cold store and NH3 is used as the refrigerant providing indirect cooling outside the cold store.
The system needs only 3 tonnes of ammonia refrigerant compared with 30 tonnes for a conventional ammonia cold store. On the average, the system can reduce energy consumption by 30% per annum. In summer, the amount of energy saving is estimated as being 50%.
In China, rising market demand of seafood and other frozen food is creating a big market for NH3/CO2 cascade systems. Several domestic manufacturers have begun to produce NH3/CO2 cascade refrigeration systems and several supermarkets and food cold stores have already used the technology.
Yantai Moon produced China’s first domestically made NH3/CO2 screw cascade refrigeration system in 2008. In 2012, Yantai Ningxing showcased its NH3/CO2 cascade refrigeration system at the China Refrigeration Exhibition. An NH3/CO2 cascade refrigeration system has been successfully installed at Yantai Fengrun, a local Chinese fruit pudding supplier to McDonald’s and Weihai Jiuye, a Chinese export-seafood supplier in the Shandong Province.
