Although in many applications natural refrigerants remained the ‘emerging technologies’ on display, leading companies like Mayekawa, CAREL, thermea. Energysystems and Itomic quickly turned their attentions to Korea to showcase their CO2 technology and share their success stories with R744.com.
During the 2000 Olympic Games in Sydney, Australia, Greenpeace challenged Coca-Cola to stop using hydrofluorocarbon (HFC) gas as a refrigerant in its millions of vending machines and beverage coolers worldwide. The campaign worked, probably well beyond Greenpeace’s wildest dreams. Coca-Cola’s Tomas Ambrosetti and Steven Cousins explain how the Company’s number of HFC-free units installed worldwide has grown to 1.4 million in the feature interview of the 4th edition of Acceler
Hurtigruten’s cruise liners allow tourists to discover the landscapes of Norway, as well as experience natural phenomena such as the northern lights and the midnight sun. However, like all transport and tourist activities, Hurtigruten’s operations have a direct influence on the environment. The company’s environmental policy therefore has an important role to play, and as part of their sustainability practices, Hurtigruten’s terminal in Bergen uses the natural refrigerant
Kaori’s entrance to the Chinese commercial heat pump market in 2015 was a welcome one. With the revised China Environmental Protection Law to take effect in 2015, the company is intent on meeting the increasing demands for CO2 heat pumps.
The tiny Northern Swedish town of Gällivare has become home to the one of the country’s largest CO2refrigeration installations.
R744 innovations from Japan Part 2: integrated systems and improving CO2 system efficiency in warm climates
In part 2 of our reporting on the CO2 technology innovations discussed at ATMOsphere Asia 2015 we focus on the presentations from Carel, Bitzer, and Danfoss on integrated CO2 systems and technologies to increase the energy efficiency of CO2 in warm climates. These include more traditional systems such as mechanical subcooling and newer ones such as parallel compression and ejectors.
The use of CO2 as a refrigerant is becoming increasingly widespread in food processing industries, and is beginning to make inroads in industrial heat pump applications. TINE Dairy, which is Norway’s largest producer, distributor and exporter of dairy products, is committed to upholding its sustainable profile and strives to keep up to date with the most climate friendly and energy efficient technologies. With this in mind, TINE’s factory close to the city of Trondheim in
The new IntelOil is designed to electronically control the oil level in the compressor crankcase, using high resolution float-sensor technology. The standard product has a maximum working pressure of 60 barg and the high pressure version has a maximum working pressure of 120 barg, which is suitable for use in transcritical CO2 systems.
In part two of our reporting from the 49th Supermarket Tradeshow (SMTS), which took place from 10-12 February 2015 in Tokyo, Japan, R744.com reports on the first rack-type CO2 transcritical booster system installation, a collaborative project between Japanese showcase manufacturer Fukushima Industries and system manufacturer Nihon Netsugen Systems.
