Welcome back!

In previous courses, you have learned a lot about heating and cooling. However, we neglected the control of humidity in air, which is very important for the indoor environmental quality and for the conservation of materials and art (like in museums) as you can learn in the course: Health and Comfort. During module 2 you will learn about the properties of humid air, which processes can be used to heat, cool, humidify and dehumidify air and how to make estimates of the energy needed for these processes using equations and psychrometric charts. This is the basis for the other modules of the course, in which you will apply the knowledge.

Enjoy!
