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 refrigerant in transport refrigeration and it has a 100 year 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.

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.

The system is said to use 60% to 80% less energy than a conventional diesel-powered system with the same cooling capacity.

The Ecooltec TM182 chiller is an electrically-driven transport refrigeration unit using CO2 and the hydrocarbon refrigerant R1270 (propene) and does not require an integrated diesel engine.

The system is protected from leaks in the body with a patent-pending, fully hermetic refrigeration circuit. The system uses 90% less refrigerant than a conventional transport refrigeration system.

In the box body, the natural refrigerant CO2 is used for the cold distribution. Outside the body, the R1270 and CO2 circuits flow past each other, thermally connected via a plate heat exchanger.

Ecooltec Grosskopf says that the system is suitable for the most demanding applications with high loading volumes and extremely low cold room temperatures, as well as frequent door openings. It claims maximum temperature security and the shortest pull-down times under all conditions.

With a height of 250mm the TRU is designed for complete integration into the vehicle without any significant loss of loading volume.

The ECOOLTEC unit produces neither local pollutant nor CO2 emissions when in battery operation, and up to 98 percent fewer emissions via the alternator drive.

ECOOLTEC already uses future-proof natural refrigerants for all its electrically driven transport refrigeration machines.

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.
