The key difference is that as the air increases in temperature it can hold more water. The psychrometic chart shows the relationship between air and water. As air takes up water it moves along the line of constant energy D. If the ambient ...
Web5. Adiabatic Mixing of Air Streams: Very often air having different conditions are mixed in the air conditioning system, such as the mixing of fresh air and return or re-circulated air before it enters the process plant. The psychometric chart can be used to find the resulting condition of the mixture.
