Eco cool

Eco cool bangalore-based Trac Fujico Air Systems Ltd has become the country's first indigenous manufacturer to develop and introduce air conditioners (ac s ) that do not use hcfc (hydrochlorofluorocarbon). hcfc , used widely as a refrigerant, is a potential environmental hazard as it contributes to the depletion of the ozone layer.

Ozone depletion was one of the primary environmental concerns of the last decade when, alarmed by a rapidly-growing hole in the Earth's ozone layer, nations pledged to cut down their use of ozone-depleting chemicals. The ozone layer is critical for our survival, as it absorbs most of the harmful radiation from the Sun. In 1987, through the Montreal Protocol, most developed countries banned the production and use of chloflurocarbons ( cfc s) and halons, the main chemical agents behind the gaping hole in our ozone layer. Certain industries were affected initially, such as the aerosol and refrigeration sectors since these made extensive use of cfc s. Prior to the Montreal Protocol, household and industrial refrigerators, ac s and all other cooling devices used cfc s as their primary cooling agent. Though the ban made these machines obsolete in the West, many of them are still functional in the developing countries. One good sign came earlier this year, when scientists declared that cfc -usage had indeed gone down over the last 10 years. The threat to the ozone layer, however, is far from over. Seeking alternatives to cfc s, industries switched to other chemicals, one of which was hcfc . As the name suggests, it is not very different from their cfc s. Apart from posing a significant threat to the ozone layer, it also contributes to global warming. So thus began another movement, and this one tried to curb the new ozone threat
