Transport Refrigeration

The term ‘transport refrigeration’ covers several applications including refrigerated vans, refrigerated trucks and trailers and fishing vessels.

HFC 404A is the most commonly used in transport refrigeration and it has a 100 yr GWP of 3922. A leak of just 10kgs of this potent greenhouse gas has the same impact as a passenger car driving for almost a year! Transport refrigeration is now focused on natural alternatives including CO2, ammonia, liquid nitrogen and hydrocarbons.

With operations in Scandinavia and the Baltic region, AGA provides both direct and indirect cooling systems. The flexibility of these systems offers the possibility to either cool trailers in total or trailers separated into different chambers or trolleys. The systems can use dry ice and carbon dioxide to refrigerate dairy, meat, frozen and other perishable food products during transportation. Carbon dioxide cools the air in the vehicle via a heat exchanger and is then vented out through the top of the car. The system will use the warmed cooling water from the car engine to maintain the prescribed temperature in the chamber if needed. The system offers full control of temperature conditions and is free of noise.

American Freedom, one of the world’s largest reefer ships, uses a cascade ammonia and CO2 refrigeration system, helping to generate a cooling output of 4,500kW. The cascade system is able to process around 400 tons of fish per day, storing catch in the hull of the ship where there are 36 vertical plate freezers in operation.

According to DSI, the change from HCFCs to CO2 freezers on board ships yields greater efficiency, as CO2 freezers can attain cooler temperatures (CO2 reaches -50°C, while HCFCs reach -38 to -40°C).

DSI designs and manufactures plate freezers for on-shore and marine installations for transporting and processing seafood. The company offers CO2 plate freezers for installation worldwide. Currently, the company has over 500 CO2 plate freezers in operation in Europe.

Under the name ‘NaturaLINE’, Carrier Transicold (a division of Carrier) has developed the world’s first container refrigeration system using CO2 as the refrigerant. Working with the German shipping company Hapag-Lloyd Carrier has been testing its new system since 2010. Carrier aims for improved refrigeration performance and reduced power consumption.
The CO2 refrigeration system is one of the world’s first entirely naturally refrigerated trailers and is being trialled by Sainsbury’s since 2013. If rolled-out across it’s transportation fleet, Sainsbury’s estimates the Carrier NaturaLine system will reduce the company’s CO2e emissions by 70,000 tonnes each year.
The new NaturaLINE design has been engineered to deliver efficiencies equal to Carrier Transicold’s best-in-class performer, the PrimeLINE unit. By using CO2 as a natural refrigerant, the NaturaLINE design improves upon the PrimeLINE unit’s ability to reduce carbon dioxide emissions 28% compared to previous units.
The CO2 system is in use by shipping companies worldwide.

In 2010, Shoprite became the first South African retailer to use nitrogen-based refrigeration in its transport fleet. The natureFridge systems use liquid nitrogen cooled to -196°C, before being dispersed evenly inside the trailer. One trailer can reportedly save up to 38 tonnes-CO2e tonnes per year.
As of 2014, Woolworths Holdings Ltd. had 4 of these vehicles in operation, with another one in the process of being built. The company reports savings of 3000 tonnes of CO2 per annum as a result of this transition.

Have your say!

ATMO Intelligence, the Market Development division of shecco invites air-conditioning and refrigeration stakeholders to participate in a survey that assesses the F-Gas Regulation, sector by sector, while also looking into what should be included in an upcoming revision of the regulation.

Respondents select the sectors they are active in and complete a custom survey based on their interests. “With these results, we will produce a comprehensive report that will be shared with policymakers across the EU to drive more progressive change, particularly in terms of refrigerants and getting rid of harmful gases in all sectors – from transport refrigeration to domestic air conditioning,” said Ilana Koegelenberg, Market Development Manager at shecco.

Once completed, the report will be freely available for download.The survey should take around 15-20 minutes.
