14/8/2018

For blog readers who may relish a scientific conference about water—The Welch Foundation Conference on Chemical Research "Water: Science and Technology" will take place in Houston, TX October 22-23, 2018. I am going! You can learn more about the conference at http://www.welch1.org/conference/conference-program —be warned— the experience will likely be similar to attending university lectures in chemistry and physics!

Water-from-Air Quick Guide

In response to a reader's comments, the July 2018 reprinted second edition incorporates enhanced temperature versus relative humidity psychrometric tables in Chapter 4 with wider temperature ranges (0–55 °C; 32–132 °F) for finding water vapour density, humidity ratio, and dew-point. This makes the tables more useful for cities like Abu Dhabi, Doha, and Dubai.

This reprint also has a revised Appendix 6: Economics of Off-grid Solar PV for WFA. There are two detailed examples in the Appendix. The first example is for a 1.05 kW input power atmospheric water generator using 1-phase electric power. The second example is for a 2.1 kW input power atmospheric water generator using 3-phase electric power.The Appendix presents clear diagrams showing the main components of single-phase and three-phase off-grid solar PV systems. The Appendix concludes by revealing, for each example, the ratio comparing the price of an off-grid solar PV system to the price of the atmospheric water generator.

The Water-from-Air Quick Guide may be purchased from Amazon.
