Abstract

The Curricular Integration Work project presents the dimensioning of an atmospheric water generator equipment to produce drinking water by condensing the humidity in the air. The prototype uses the active method cooling by refrigeration cycle, to condense 3 liters of water per day in Quito-Ecuador. To size the atmospheric water generator equipment, is calculated the thermal load required to cool the air below the dew point and condense the steam, using an evaporator temperature of 0 [ºC]. Determine the heat released and compressor power using condenser temperature of 60 [ºC] and the refrigerant R-134a. To determine the heat transfer areas of a flat plate evaporator, and a tube and wire condenser, is used the logarithmic average of the temperature difference and an analysis of the heat transfer coefficient in each heat exchanger. To select the evaporator and the condenser is considered a area 10% higher than the calculated. In the selection of a hermetic piston compressor, a compressor is chosen with a 10% higher coefficient of performance than refrigeration cycle, and the use of Secop Capillary Tube Selector for the selection refrigeration capillary tube. Based on the results, the atmospheric water generator equipment consists of a doble sided roll evaporator with a total outside area of 1.287 [m2] , a 1/3 HP model wire and tube condenser with a total outside area of 0.88 [m2], an Embraco hermetic piston compressor model EMIS30HHR and refrigeration capillary tube with length of 2.15 [m] and an inside diameter of 0.90 [mm] corresponding to a domestic system.
