Summary

This article is the Spanish translation of an article presented at the 22nd IIR international Congress in Beijing, China (see the Bulletin of the IIR, reference 2007-2195). Small window air conditioners and split units for cooling air in residential buildings, even large apartments and office buildings may not only spoil the architecture and the appearance of buildings, cause extra construction costs, but lead to uncontrollable refrigerant escaping which destroys the environment. Moreover, most of such room air coolers consume too much energy. Based upon typical negative examples of such installations? this paper shows simple means to reduce energy demand for cooling by some 50%. It must be in the interest of every country in avoiding energy waste and in room air cooling which has a huge potential after the improvement of this situation. We should bear in mind that in hot (and humid) countries, some 45% of the total electric energy is presently used in demand of mere cooling buildings. In other words, it is important to save energy. A number of investigations show the deficits of small so-called "air conditioners" compared with available state-of-the-art technologies. Such deficits of small air conditioners cannot be neglected but propulsion to take actions against the horrendous waste of energy.
