The impacts of air conditioning and refrigeration systems on environment are primarily linked to ozone-depleting refrigerants, energy consumption and heating the environment. Integrated assessment of ozone depletion, global warming, and atmospheric lifetime provides essential indications in the absence of ideal refrigerants, namely those free of these problems as well as safety, stability, compatibility, cost, and similar burdens.
The basic principle relies on cooling by evaporation. When water evaporates it draws energy from its surroundings which produces a considerable cooling effect. Evaporative cooling occurs when air, that is not too humid, passes over a wet surface; the faster the rate of evaporation the greater the cooling. The efficiency of an evaporative cooler depends on the humidity of the surrounding air. Very dry air can absorb a lot of moisture so greater cooling occurs.
This paper aims at finding ways to substitute Air-conditioning with Evaporative cooling and the present efforts in this direction.
