Follow the to find the Wet Bulb temperature.
The psychrometric chart graphically represents the physical and thermodynamic properties of moist air at a constant pressure (usually standard atmospheric pressure). how do you read a psychrometric chart
Found by following a horizontal line to the left until it hits the saturation curve. It is the temperature where condensation begins. Follow the to find the Wet Bulb temperature
To read the chart, you need two known properties. With two properties, you can find the intersection—this is called the . Once you have the State Point, you can determine every other property of that air sample. It is the temperature where condensation begins
The true power of the chart is visualizing what happens when you heat, cool, or humidify air.
Since humans feel comfort based on a mix of temperature and humidity, the chart helps designers find the "sweet spot" for indoor environments.
The horizontal axis along the bottom. What it is: This is the standard air temperature measured in °F or °C. How to read: Find the number on the bottom. Follow the vertical line straight up. Every point on that vertical line represents that specific temperature, regardless of how much moisture is in the air.
