Psychrometric Chart

A psychrometric chart is a chart and 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. It is a tool that can make it easier to troubleshoot air-conditioning problems in buildings.

The psychrometric chart is built upon two simple concepts.

1. Indoor air is a mixture of dry air and water vapor.

2. There is a specific amount of energy in the mixture at a specific temperature and pressure.
