Resumo(s)
The problem of water scarcity is nowadays one of the themes under discussion around the world. Currently arise increasingly prevention measures, as well as have been developed and improved systems of production, treatment and storage of water. Based on this serious problem lived by a considerable part of the world's population, the present work proposes the use of a simple dehumidification system to obtain water from a renewable source of water, the Earth's atmosphere. Results will be presented concerning the capacity and costs of this type of equipment to produce water. Although the extracted water, from the atmospheric air by condensation of water vapour, in vapour compression refrigeration systems, require treatment and to be mineralized, this equipment can be used in any house as a source of drinking water. The work includes conducting experimental studies, in a climatic test chamber, using a commercial equipment with a dehumidifying capacity of 20 l/day, for values of 30 ºC and 80% of relative humidity and temperature, respectively. This equipment has an operating range of 5-32 ºC for the temperature and 30-90% for the relative humidity. The tests were realized with The largest production of water occurred for ambient conditions, inside the climate chamber of 43 ºC and 43%, temperature and relative humidity, respectively, being obtained 0,3 l/h.
