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.
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.
