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 reports that the water-cooled hydrocarbon integrals have resulted in energy efficiency gains of around 29% since 2012.

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.

By January 2012, Unilever had placed over 900,000 hydrocarbon ice cream freezers around the world, including South Africa, China, Europe, Brazil, and a trial in the United States. According to Unilever reports, these freezers contain less than 150g of hydrocarbons in their refrigerating circuit, and have a 9% energy savings over their HFC counterparts.
The company will reach the 1-million unit mark by the end of 2012, and by 2015 all of Unilever’s new ice cream freezers will be HFC-free. In an industry precedent setting move, Unilever pioneered the testing of hydrocarbon ice cream freezers in the United States in its Ben & Jerry’s ice cream stores. In 2008, the company requested from the EPA to test up to 2,000 units.
With this move, Unilever penetrated the wall of regulatory obstacles that had, until then, kept hydrocarbon cooling technologies out of North America. Unilever was instrumental in influencing the EPA’s subsequent approval of hydrocarbons in 2011.
In 2012, the company announced plans to roll-out hydrocarbon freezer cabinets in the US for other Unilever brands (including Breyers, Good Humor, Klondike, Magnum and Popsickle). In 2016, Hindustan Unilever, an India-based subsidiary of Unilever announced it was rolling out freezer cabinets that use hydrocarbon refrigerants. Unilever claims that its HFC-free point-of-sale freezers have the potential to reduce energy by 70% compared to its 2008 baseline, making them 20% more efficient than the current technology.

Energy Efficency
Carrier claims that the CO2OLtec Evo can achieve a 52% Annual Energy Consumption (AEC) vs. an average 2009 store and 38% AEC vs. an average 2012-2013 store.

A United Technologies Company, Carrier is the world’s largest producer of heating, ventilation, air-conditioning and refrigeration systems. Under the CO2OLtec label, the company has developed CO2 refrigeration systems for supermarkets and other large applications. Carrier developed a two-step technology with the refrigerant that allows the pressure on the supermarket shop floor to be kept at around 40 bars with only the plant areas requiring higher pressures.The Carrier CO2 integrated system uses one central compressor pack device to operate the air conditioning and heating equipment as well as the refrigerated cabinets. “With one device managing all these functions efficiently together, energy consumption can be optimized. In addition, the waste heat from the system can be reused in operations, reducing CO2 emissions.” In September 2017, Carrier announced it had installed over 6500 racks, the majority of which are CO2 transcritical. Carrier also produces hydrocarbon based refrigerated cases and display cabinets.

Estimated energy savings of 10-20% achieved from pilot stores

Carrefour’s Nichelino store in Northern Italy uses a CO2 Transcritical system with parallel compression, heat recovery for tap water and facility heating (400 kW) and liquid and gas ejectors. It was designed by Swiss refrigeration consulting and engineering company Frigo-Consulting. The system reduces the store’s carbon footprint by reducing both direct and indirect emissions, achieving the former by switching from R-404A (whose GWP is 3,922) and R-134a (GWP of 1,430) to CO2 (GWP of 1), and the latter thanks to the advanced refrigeration and the reduced energy for heating.

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 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.
