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.
Catalysed by EIA’s Chilling Facts campaign the global supermarket sector is now shifting towards natural refrigerants.
European retailers are at the forefront of this trend with 10% of the European food retail sector using natural refrigerant based refrigeration (excluding small stores).
Refrigeration systems account for up to 60% of the total energy used in supermarkets, making energy efficiency improvements vital to reducing the climate impact of the sector.

Waitrose Supermarket
Waitrose Supermarket
As of 2017, UK company Waitrose had 168 stores operating on a complete hydrocarbon integralized system. These equate to around 48% of the company’s total number of stores. This water-cooled/propane natural refrigerant system will be installed in all stores by 2020 and a program of work is underway to achieve this. The company estimates that the propane refrigeration technology will reduce its carbon footprint by 20%. Waitrose reports that the water-cooled hydrocarbon integrals have resulted in energy efficiency gains of around 29% since 2012. The system is based on a combination of high-efficiency air-cooled chillers supplied by Klima-therm and manufactured by Geoclima that utilize R290 propane and use water as the condensing medium to supply Carter Retail Equipment integrated cabinets operating on propane hydrocarbon-based scroll compressors. It makes use of split coils to keep the propane charge under 400g, together with liquid pump amplification and floating head pressure and conventional free cooling below 18°C. The system design allows for the harnessing of heat from the integral refrigeration units to deliver warmth into the space between cabinets, in order to offset the in store “cold aisle” effect. This helps boost efficiency and overcomes the need for a separate heating system.

COOP Schweiz
COOP Schweiz
COOP is the second largest supermarket chain in Switzerland, with over 1000 stores. Starting in 1998, the company began to install subcritical CO2 refrigeration systems. In 2004, the company installed its first direct expansion CO2 system, and in 2009 the company opted to make transcritical CO2 booster systems the standard for new and rebuilt stores. In these systems a central system cools the network of display cabinets and walk-in coolers, in both the low and medium temperature range. These systems reduce the direct CO2 equivalent emissions for COOP from 30,000 kg to 30 kg per year. The system is engineered by Frigo-Consulting AG and installed by Alpiq InTec West AG. As of 2014, COOP had 273 stores using natural refrigerants, including one in Russia. Since 2010, all new stores and renovations have used natural refrigeration systems, with almost all of them using CO2 and giving up to 30% better energy efficiency. Furthermore, their logistics centers (distribution centers) all use ammonia. COOP has a goal to be CO2-neutral by 2023.

Coolinn Cryogenic Sauna using Mirai COLD
In October 2019, Coolinn opened a cryogenic sauna using Mirai’s air cycle refrigeration unit. Cryogenic saunas, essentially very cold rooms, are used by athletes to recover from injury and for other health benefits. Mirai COLD units use air as the refrigerant in a one stage system to reach very low temperatures up to -110C. Ambient air is free, abundant, environmentally friendly, non-toxic and non–flammable, and there is no need for refilling – making it the ideal refrigerant. The Mirai Cryo uses nitrogen instead of air and can achieve temperatures from -130C to -160C. . Mirai Cold units can be used for biomedical storage, food storage, freeze drying food, industrial cooling and cryotherapy.
The Mirai COLD 15 air-cycle refrigeration machine won ‘Innovation of the Year’ at the Accelerate Magazine/Europe awards in October 2019.

Al-Salam Supermarket
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.

GEA Refrigeration Technologies, formerly Grasso GmbH, manufactures a spiral chiller with finless evaporator for food freezers. Usually, heat transmitters have fins that increase the evaporator’s surface. However, this also facilitates the deposition of microorganisms and makes the facility harder to clean. Thus, there is demand for finless alternatives offering the same level of efficiency in the foods industry. The heart of the prototype is a spiral chiller equipped with a finless evaporator. The evaporator is tested by cooling 8,000 regular ice packs from ambient temperature to -37°C in 30 minutes. The refrigeration energy is furnished by an ammonia/CO2 cascade: ammonia for the high-temperature cycle and CO2 for the low-temperature cycle. The advantage is that only 40kg of ammonia is used, and it remains confined to the central machine room, while the freezer is supplied with CO2.

EsyCool green
EsyCool green
Viessmann has produced a propane-based energy system the ESyCool green to heat and cool retailer’s stores.
The ESyCool green is a highly efficient energy system that controls and optimises the flows of energy in a supermarket. ESyCool green operates based on heat pumps in combination with optimised refrigerated cabinets and cold rooms, as well as an integrated ice energy storage unit and photovoltaic system.
For a supermarket operator, this means energy savings of around 15% and a significant reduction of lifecycle costs in comparison with conventional refrigeration systems.
Enex
Enex
Enex produces commercial refrigeration systems for supermarkets, hypermarkets, cold stores and freezing tunnels using CO2 as the system refrigerant. The company specializes in transcritical booster systems as well as cascade systems. Its refrigeration systems can also be implemented to use system waste heat for heating purposes in stores. In 2017, it launched an integrated heating and cooling system designed to suit any store size. As the heating comes from heat recovery the energy use associated with heating is zero.
Elcold
Elcold
Elcold is a manufacturer of chest freezers and coolers for both commercial and domestic applications. In the XLE-range, they have increased the insulation to 100 mm. This, in combination with an environmentally friendly refrigerant and optimized compressor, saves on energy and direct global warming impacts.
Derby
Derby
Derby, a division of Metalfrio Solutions, is a commercial refrigeration manufacturer that supplies hydrocarbon refrigerators, coolers and storage cabinets. The company also produces CO2 commercial coolers for Coca-Cola.
CSC Group
CSC Group
CSC Group developed and manufactures a patented CO2 based “ECO2-System” for supermarkets. In addition to reducing greenhouse gas emissions, the system reduces energy costs by recapturing heat from the cooling system, and using it for heating the store. The company estimates that if all 6,500 grocery retailers in Canada would use its ECO2-System, the GHG emission reduction would be equivalent to taking 2 million cars off the road. The cost of maintaining the ECO2-System is reported to be significantly less than competitive systems using HFCs. In 2011, CSC installed the world’s first 100% CO2 ice rink in the Marcel Dutil Arena of the town of Les Coteaux, Quebec. The company’s Eco-2-System uses only CO2, replacing both the use of HCFC-22 and ammonia, in a transcritical refrigeration cycle. The system uses a Danfoss ICMTS valve to regulate the flow of CO2.
