Psychrometric charts are complex graphs that can be used to assess the physical and thermodynamic properties of gas-vapour mixtures at a constant pressure. They are often used to assess the properties of moist air.

Is psychrometric chart accurate?

While this method is not accurate enough for laboratory calculations, it is useful for field calculations using the psychrometric chart, where extreme accuracy is not of prime importance. On most psychrometric charts space is limited so that only the total heat content of the air is shown.

Why is psychrometric chart important?

The psychrometric chart is an industry-standard tool that is used to visualize the interrelationships between dry air, moisture, and energy. If you are responsible for the design or maintenance of any aspect of air-conditioning in buildings, a clear and comfortable understanding of the chart will make your job easier.
