Commercial Refrigeration

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.
