New components are helping to bring CO2 refrigeration systems to warmer climates and heat pumps can broaden the application of this natural refrigerant still further, Giovanni Dorin, the company’s marketing director, told.
Japanese manufacturer Mayekawa sees natural refrigerants playing a huge role in industrial refrigeration, both now and in the future.
An SCM Frigo-designed CO2 system in an Italian supermarket featuring parallel compression, a CO2 heat pump and air conditioning is delivering strong energy savings.
SPAR expects the system to improve energy efficiency and reduce the distribution centre’s carbon footprint. The new facility in Ebergassing is one of the most innovative and sustainable in the world, according to Gerald Geiger, director (building/energy/technology) at SPAR Austria. “Carrier’s CO2 system meets our need for a long-term, cost-effective solution,” he said.
Demand for copper piping capable of withstanding the high pressures of CO2 is increasing in Europe and the United States, Ronnie Nilsson of Mueller Industries told at Chillventa 2016.
Danish manufacturer Advansor is ready to capitalise on the European food retail sector’s move towards smaller stores by providing integrated heating and cooling systems, Managing Director Kim G. Christensen told at Chillventa 2016.
Coldway, a French company, has developed an ammonia mobile refrigeration unit for deliveries for the food, health and pharmaceutical sectors.
“Ammonia is here to stay, because it doesn’t contribute to global warming or harm the ozone layer,” according to Isolde Dobelin, director of the OTTC, a major training centre for using ammonia in HVAC&R applications in South Africa.
CAREL talk through their new control solutions for small-scale CO2 systems and outline their expectations for the future of CO2 as a refrigerant.

Stationary air-conditioning, commercial refrigeration and domestic refrigeration make up 80 percent of India’s installed cooling capacity. Currently 90 percent of India’s cooling capacity and annual refrigeration and air-conditioning (RAC) is based on hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFC) refrigerants, about 10 percent is based on naturals.
Tecumseh showcased its new hydrocarbon compressor range at Chillventa 2016.
Bitzer unveiled its new ECOLINE+ reciprocating compressors for CO2 systems at Chillventa.
Speaking on the first day of the Chillventa Congress, Van Baxter – an engineer from the Oak Ridge National Laboratory in the US state of Tennessee – said that the growth of the United States heat pump market was largely due to the lumber industry.
The world’s most lauded environmental treaty could be about to notch up a new success. In 1974 scientists discovered that chlorofluorocarbons (CFCS), chemicals used in refrigeration and as propellants in products such as hairsprays, release chlorine into the stratosphere as they decompose. This depletes the ozone that protects Earth from ultraviolet radiation. CFCS are also powerful greenhouse gases, which absorb solar radiation reflected back from the planet’s surface and so trap heat in the atmosphere.

German retail giant ALDI has earned LEED (Leadership in Energy and Environmental Design) gold certification from the U.S. Green Building Council (USGBC) for its ammonia distribution centre and regional headquarters in Moreno Valley, California.
The wide acceptance of new technologies depends on a myriad of factors, in the technological, economic and social field, that form part of a complex network of interactions. Both innovators and technology adopters share a common concern for respecting the economic bottom-line and for choosing solutions that provide the highest possible level of investment security while being framed by solid industry support and favourable policy conditions.
The wide acceptance of new technologies depends on a myriad of factors, in the technological, economic and social field, that form part of a complex network of interactions. Both innovators and technology adopters share a common concern for respecting the economic bottom-line and for choosing solutions that provide the highest possible level of investment security while being framed by solid industry support and favourable policy conditions. The industrial refrigeration industry is no exception to this. While the use of ammonia has not been challenged on grounds of lacking energy efficiency nor overall environmental benefits, the trend towards reducing the refrigerant charge for increased safety is currently changing the industry.
The viability of new lower GWP alternative refrigerants in high ambients are said to have been proven in new tests.
