 What's included?

I welcome you to this short but powerful tutorial about Rittal Therm, a program I use very often on my projects. It's primary goal is to help the user to calculate the heat loss (also called power loss or heat dissipation) inside electrical enclosures and to dimension the climate system (fan, air conditioning) accordingly.

In this short tutorial you are going to learn about:

  • the program itself
  • the basics of heat dissipation and how to find this parameter for different devices
  • the dimensioning of the climate system in the electrical cabinet
  • to calculate the heat loss and dimension the climate system for the example cabinet from our EPLAN courses (CAB2 - power distribution cabinet

This is the 3rd major topic in electrical design.The first one was the dimensioning of the power distribution system (we cover that one in the Simaris Course)The second one is the creation of various circuit diagrams (we covered that one in EPLAN Electric P8 courses)Now it makes sense to go further and to calculate the heat loss inside the cabinets and to dimension the necessary climate system in the cabinet.That's why this course came to life.
