WebJul 31, 2024 · The psychrometric chart explained. The psychrometric chart is a really intimidating looking graph with a ton of lines going in 6 different directions. For the sake of clarity and because conservators don't really need to use them, I have not drawn in the enthalpy or volume lines. Let's leave those to the engineers and HVAC specialists. Webwhere the actual water vapor - air psychrometric chart forms a continuum of lines. The chart relates the mixture's enthalpy to T dp, T wb, h a, h r, and specific volume. Given a combination of these properties, we would be expected to determine the enthalpy. The technique is the same for any combination of properties given.
