THE PSYCHROMETRIC CHART AND ITS USE

complicates the psychrometric processes and calculations. For example, the amount of water vapor in the air varies widely from time to time according to temperature, and the proportion of water vapor in the air must be regulated in order to provide comfortable conditions. THE PSYCHROMETRIC CHART:Theory and Applicationa psychrometric process that involves the cooling of air without heat loss or gain. Sensible heat lost by the air is converted to latent heat in the added water vapor. 1 2. Evaporative cooling:Example 10 Referring to Figure 21, air at state point 1 (65°C Your Guide to Psychrometric Chart Properties CondairDec 04, 2017 · Your Guide to Psychrometric Chart Properties. Psychrometry involves the study of moisture content in the air. In atmospheric conditions, water vapor content in air typically varies between 0% and 3% by mass. Humans require air with a specific amount of moisture in order to remain healthy, safe, and comfortable indoors, which is where proper
