Ammonia Air Conditioning to the Fore

I had authored an article titled Use of Ammonia for Air Conditioning Applications, published in the April-June 1999 issue of Air Conditioning and Refrigeration Journal (p 63). Since then, a lot of water has flown under the bridge, and my objective in writing a second article on the topic is to update the readers on developments since my first article. Ammonia has received considerable negative publicity from the man-made refrigerants lobby that is keen to recover, as quickly as possible, their huge investments made in developing these refrigerants such as HFCs and HCFCs. We, in India, have a long tradition of following what the multinationals advocate. This is true especially in the field of air conditioning technology and products.
