RESUMO

The simplest process for water to reach adequate purity is the conventional distillation, however this method has drawbacks such as their high expense with electric energy and their high water consumption. Searching alternatives to produce purified water with saving energy and water cooling, but with production as purity as conventional, there is the possibility of developing a system for purifying water by dehumidification the air with a heat pump. The equipment designed for water purification operates on a thermodynamic cycle of cooling and is composed of two parts: a heat pump vapor compression, the type air-air coupled into an air duct, and a chamber where it occurs humidifying the air, with recirculated air. Were tested also two types of humidifiers, with filling of glass and a sprayer. The water produced can be considered as purified, since it showed electrical conductivity values between 4 and 5 ms / cm. The heat pump showed a better performance when the spray was used, since the COP obtained were higher than those obtained in tests with a filling of glass on the adiabatic humidification
