Compressor manufacturer Bitzer has launched a horizontal oil separator designed to work with its ammonia screw compressors.

The 2016 editions of ASHRAE’s major refrigerants-related standards have been published as a package with 30 new refrigerants and refrigerant blends added.

Among the more than 75 educational sessions, many are related to natural refrigerant technologies.

The first round of case studies showcasing innovations for industry leaders has been selected for ATMOsphere Japan 2017.

Didier Coulomb, director-general of the International Institute of Refrigeration (IIR), argued at COP 22 that the refrigeration and air-conditioning sector can play a greater role in addressing climate change.

Hydrofluorocarbons (HFCs) are the fastest growing source of greenhouse gases globally, but also one of the areas where climate-friendly, energy-efficient alternatives, such as natural refrigerants, are readily available for a growing number of applications. In 2014, the EU took regulatory action to limit the use of these gases through a combination of measures. The EU F-Gas Regulation, which entered into force in 2015, is rapidly changing the face of European industry and influencing markets beyond Europe’s borders.

German compressor manufacturer Bitzer has established a subsidiary company in Iran.

Two ammonia heat pumps from Star Renewable Energy have been shortlisted for awards in the UK.

CO₂ Academy is the natural choice for training in transcritical CO₂ technology. As a technicians it is not only essential to understand the technical aspects of CO₂ technology, but also to acquire the relevant communication skills.

The EU’s ‘Winter Package’ of climate legislation, tabled yesterday, proposes to increase energy efficiency by 30% by 2030 in an effort to cut emissions and meet Europe’s obligations laid out in the Paris Agreement.

In mobile air conditioners, the performance and environmental benefits of using R290 surpass R22, research has found.

The Ammonia Piping Handbook serves as a guide for the design and implementation of Colmac Coil’s DX ammonia refrigeration system.

Climate change, greenhouse effect and global warming – scarcely any other issue is so omnipresent and so controversially discussed in the 21st century. Those who are convinced in doubting that climate change is man-made refer to various eras in the history of our planet where the earth has heated up or cooled down drastically even without any contribution on our part. In future too, they see climate change as the result of natural causes, including among others a changed ellipsoid orbit of the earth around the sun.

The decision as to which refrigerant should be used in a refrigerating or air-conditioning system is based on the major criteria of safety, costs and environment protection. But against the background of constantly increasing energy prices, the energy consumption of a system also plays an increasingly important role. Ideally, the chosen refrigerant should have excellent thermodynamic properties, high chemical stability and good physical characteristics. Furthermore, it should have no or only a negligible impact on the environment, while also being inexpensive and available worldwide.

This report characterizes the current landscape and trends in the global A/C market, including discussion of both direct and indirect climate impacts, and potential global warming impacts from growing global A/C usage. The report also documents solutions that can help achieve international goals for energy efficiency and GHG emissions reductions. The solutions include pathways related to low-global warming potential (GWP) refrigerants, energy efficiency innovations, long-term R&D initiatives, and regulatory actions.

Facility managers count on efficient, safe refrigerant solutions to provide cost-effective comfort to building occupants. Today, future refrigerant options are being discussed. Alternative refrigerants are under development; a few are already on the market. With an upcoming refrigerant transition, now is the time for facility managers to learn about what’s changing and why. Facility managers who educate themselves now will be in a better position to make the best equipment choices in the future based on refrigerant safety, efficiency, reliability, cost, and availability.
