Grosvenor Humidity Chart

摘要

Ashrae Journal and designers of air conditioning, drying, dehumidification, food science and humidification processes, and meteorologists celebrated the 100~(th) anniversary of Willis H. Carrier's hygrometric chart in 2004. Four years later, we celebrate the centennial of the humidity chart produced by William Mason Grosvenor Jr., Ph.D., a chemical engineer of New York City. Both charts are now known as psychrometric charts in most of the world and as Mollier h-x charts in parts of Europe.rnA quick comparison of the lives of the two chart creators is shown in the sidebar "Lives of William Mason Grosvenor and Willis Haviland Carrier." Grosvenor and Carrier were recentrncollege graduates and newly employed in an industry that would benefit significantly from the psychrometric chart.
