Commercial Refrigeration

The commercial refrigeration sector accounts for approximately 26 per cent of the heating, ventilation, air-conditioning and refrigeration (HVACR) sector’s total greenhouse gas emissions.

Commercial refrigeration encompasses refrigerators and freezers used in supermarkets, shops, offices and hospitality and other commercial spaces. This product list features centralised systems, condensing units, standalone systems, waterloop systems and vaccine coolers.

The new systems have reduced energy consumption during refrigeration operation by 10-20% compared to previous HFC systems

AEON is one of the largest retailers in Asia and is also a member of the Consumer Goods Forum. The company operates stores under several brands, including JUSCO and MaxValu. Since 2009, the company has been testing and optimizing a Sanyo CO2 direct expansion refrigeration system for supermarket showcases in Japan. In 2012, the company unveiled a plan to go HFC-free with natural refrigerants: 10% of all new stores in 2012, 15% of all new stores in 2013, 25% of all new stores in 2014 and 100% of all new stores in 2015. The company also plans to gradually convert the refrigeration systems in its existing 3500 stores. As of February 2017, it had 99 supermarkets using CO2. The new systems have reduced energy consumption during refrigeration operation by 10-20% compared to previous HFC systems and reduced CO2 emissions by about 50%.

The system was found to save 20-30% more energy than a similar sized HFC system in a nearby shop and is expected to save hundreds...

The first transcritical CO2 refrigeration system was installed in a supermarket in Amman, Jordan in March 2018.
The system at the Al Salam military supermarket will act as a test bed for HFC-free technology in high ambient countries. It is being implemented by UNIDO and CCAC with the support of the Ministry of Environment of Jordan.
The new CO2 transcritical booster system with parallel compression replaced an R-22 system. To ensure high efficiency, the system also uses multi-ejector technology and non-superheated evaporator technology. The waste heat will be recovered for hot water supply.
The energy use of the supermarket will be monitored to observe and record the energy efficiency gains of the new system. The system was found to save 20-30% more energy than a similar sized HFC system in a nearby shop and is expected to save hundreds of dollars per year.
The technology supplier of the project is Abdin Industrial, a Jordanian family-owned company, which provided the four and five door cabinets, set up all piping and finalised the on-site installation. The company worked closely with Italian-based international system manufacturer Enex who supplied the refrigeration system. Core components used in the installation come from Alfa Laval, Danfoss, Dorin, Lu-Ve, Temprite and others.

Organisations involved in the pilot are already investigating ways to work with government to expand adoption of the technology across the country, where HFC and HCFC refrigeration is widespread.

Reported that a new CO2 transcritical systems will consume approximately 10% less energy than a similar HFC system.

Belongs to the Ahold-Delhaize group. As of 2017 it owned 998 stores of which 367 stores were operating on HFC/CO2 hybrid cascade systems and a further 63 were using CO2 transcritical refrigeration. Albert Heijn has committed to using transcritical CO2 systems in all new Dutch installations.
