The Matlab code for plotting the absolute humidity at different relative humidity levels against temperature. Plotted for relative humidity levels of 0.2, 0.4, 0.6, 0.8 and 1 with absolute humidity varying from 0.005 to 0.05 g/g and temperature from -10 to 40°C - Figure 3 Data_Fig8-11: Figure 8: Specific water yield of active cooling technology against the condensation temperature, ranging from 0 to 20°C in A and 0 to10 °C in B, in A) a humid climate (phi = 80%, T = 25°C). Figure 9: Plot of maximum specific water yield as a function of ambient temperature, ranging from 0 to 35°C, at different relative humidity levels (0.2, 0.4, 0.6, 0.8, 1) for water extraction from the air by active cooling. Figure 10: Plot of maximum specific water yield against absolute humidity, ranging from 0 to 0.035 g/g, at different relative humidity levels (0.2, 0.4, 0.6, 0.8, 1) for water extraction from the air by active cooling. Figure 11: Plot of maximum specific water yield against ambient relative humidity, ranging from 0.2 to 1, at different ambient temperature levels (5, 10, 15, 20, 25, 30 and 35°C) for water extraction from the air by active cooling. Data_Fig15-16: Matlab code for generating Figure 15 and 16: Figure 15: Maximum specific water yield of a passive solid desiccant based water-from-air extraction device against ambient temperature, ranging from 0 to 35°C. The curves pertain to different desorption temperatures: 40, 60, 80 °C and no sensible heat. Figure 16: Specific water yield of a passive solid desiccant based water from air extraction device against ambient temperature, at a relative humidity of 40% at different heat of desorption values, 2500, 2900, 3300 and 3700 kJ/L at Tdes = 60°C.
