‘Advanced Cooling’, launched last weekend at the Clean Energy Ministerial in San Francisco, challenges governments and businesses to develop and use efficient, smart, affordable and climate-friendly cooling technologies.
CO2 is termed a “Natural Refrigerant” because it exists in the natural environment. Release into the atmosphere from refrigeration systems has a negligible effect compared to other CO2 sources that are driving the global warming debate. As a refrigerant, it is a manufactured product that conforms to strict purity specifications. Its physical properties require special handling.
Daikin says the “mildly flammable” refrigerant R32 will be used in its VRV air conditioning systems in the future.
With the introduction of the revised EU Ozone Depleting Substances Regulation and the introduction of a Climate Change Policy by the UK Government, it is considered likely that more refrigeration system designers and users will be turning to alternative refrigerants such as hydrocarbons. The increased application of this technology will bring with it many technical and safety issues.
Fluorocarbon refrigerants are synthetic chemicals which usually have a high global warming potential, and some still have the potential to cause damage to the ozone layer as well if released to the atmosphere.
Climate change is an increasingly important global concern with far reaching effects. The heating, ventilation, air conditioning, and refrigeration (HVAC&R) industry is allotting a significant amount of effort to reduce the environmental impacts of HVAC&R systems. Discussions about the climate impact is often limited to the GWP of the fluids used, but this is far too restrictive, as it does not take into account the real emissions of fluids, and ignores indirect emissions, especially those related to energy use over the life time of the equipment.
A US manufacturer exhibited a ductless air-cooled water chiller using Opteon XL55, a lower GWP replacement for R410A, at the 2016 AHR Expo which opened on 25 January 2016.
This practical guide is designed to improve the skills and knowledge of professionals in the refrigeration sector that need to be certified in accordance with the requirements of the EEU (Eurasian Economic Union). The guide contains basic information on refrigeration equipment, main components of the refrigeration system, Besides, it provides information on commercial, industrial and mobile air conditioners, transport refrigeration, brazing of pipes of the refrigeration system, etc.
The European Commission is to refer Germany to the Court of Justice of the EU for its failure to apply the MAC Directive.
New initiatives on reducing the consumption of HFC refrigerants are expected to save the emission of more than 1 billion tonnes of CO2 equivalent by 2025.
Although global availability is still limited, as of March this year sales of air conditioners using the “mildly flammable” refrigerant R32 had already passed 3 million.
Daikin has approved the use of “alternative materials for jointing and piping” on its air conditioning and heating systems.
A team at the University of Wisconsin-Madison is working with new materials in an effort to produce a viable energy efficient 3D-printed heat exchanger.
In a move to encourage the adoption of R32 refrigerant, Daikin is to offer rival manufacturers worldwide free access to its patents.
Green Point, Bitzer’s compressor remanufacturing operation, is expanding its service in the UK to include other makers of compressor.
The cooling demands of large hyper data centres are set dramatically change the market for precision cooling over the next five to 10 years.
First it went tiny with the mini-VRV, now Daikin has launched an “invisible” VRV air conditioning system.
HFO-1336mzz(Z) is to be promoted as a potential working fluid for high temperature heat pumps at this week’s ICR 2015 conference in Japan.
