Honeywell releases low GWP R404A option
Honeywell has announced the availability of Solstice L40X, aka R455A, its low GWP replacement for R404A.
Ozone hole 2016 back to normal
The 2016 Antarctic Ozone Hole size reached 23 million km2, 5 million km2 smaller than the record 2015 hole, whose larger size was due to colder-than-average temperatures in the stratosphere, while warmer temperatures were encountered this year.
Chillventa 2016: bigger than ever
Chillventa 2016 is bigger than ever, with a 13% increase in the size of the display area. From 11 to 13 October 2016, on what will be its fifth appearance, Chillventa will once again turn Exhibition Centre Nuremberg into the world’s biggest and most important international gathering for the refrigeration, AC, ventilation and heat pump sector. As always, the Chillventa CONGRESS was held the day before the trade fair. As in previous years, the conference is quite impressive with its high-calibre programme and top class speakers from all over the world.
Opportunities for CO2 heat pumps in the lumber sector?
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 Montreal protocol. To coldly go
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.

ALDI wins environmental award for ammonia distribution centre
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.
Examples of NH3/CO2 secondary systems for cold store operators
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.
New low GWP synthetic refrigerants
In this project, two newly developed refrigerants, R1234yf and R1234ze have been studied as promising drop-in replacements for the common high global warming potential refrigerants. In view of that, thermodynamic and transport properties of new refrigerants were obtained by RefProp version 7.01 to study and compare their cycle performances with current refrigerants. Furthermore, their environmental and safety aspects have been studied in order to predict probable risks and suitable preparations in different applications. Basic cycle data of both new refrigerants have been calculated for most commonly used condensing and evaporating temperatures. According to evaluation of these tables, both refrigerants generally have comparable COP and volumetric cooling capacity with R134a for an isentropic compression.
Low GWP refrigerants win at high ambients
The viability of new lower GWP alternative refrigerants in high ambients are said to have been proven in new tests.
