Ammonia

Store cuts energy consumption by 33% and saves $74,640 over 13-month period, thanks to cascade system and other improvements.

Standards, codes and legislation must be adapted to encourage wider rollout of HFC alternatives, argues an upcoming European Commission report.

France sees natural refrigerants as market-ready alternatives to HFCs, according an energy ministry official.

A new paper published by the UK Institute of Refrigeration (IOR) considers the future choice of refrigerant for small industrial refrigeration applications.

The European Commission has warned that the uptake of training in alternative refrigerants is too low to match the requirements of the F-gas phase down.

Nine national refrigeration associations met with a UN body in Belgrade, Serbia recently to tackle the HCFC phase out and hear about how to leapfrog HFCs by using natural refrigerants.

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

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.

The Defense Commissary Agency (DeCA) currently operates a 117,000-square foot commissary in San Antonio, Texas. The store is located in the community service area of the Lackland Air Force Base and is surrounded by other retail stores, banks, schools, and housing.

Heat exchanger, tied to the U-Turn NH₃ separator, to serve growing market for cascade systems.

The growing popularity of “natural” refrigerants has prompted A-Gas to add ammonia to its UK product range.

“The use of natural refrigerants [like ammonia] is probably more prevalent in breweries than in most industrial or commercial refrigeration plants,” said Mark Bulmer (global segment manager (cooling), GF Piping Systems) at BrauBeviale an international beverage trade fair taking place in Nuremberg, Germany on 8-10 November.

Investigators have so far refused to confirm or deny whether the refrigeration system was the source of yesterday’s fatal ammonia leak at the Carlsberg brewery in Northampton.

Johnson Controls’ chiller and heat pump units use no more than 49 kg (108 lbs.) of ammonia.

Kysor/Warren, a division and brand of global refrigeration equipment maker Heatcraft Worldwide Refrigeration, is optimistic that deployment of natural refrigerant technologies will expand in the U.S., but the company admits there are some obstacles to overcome.
