Is there a norm for citing sections in other chapters? That is, when I am in Chapter 3 and refer to section 2 in chapter 2. Do I write "Section 2.2" or "Chapter 2.2" or Section 2 of Chapter 2. Logically Section 2.2 seems to be the correct way, since 2.2 is not a chapter but part of a chapter ... I actually saw all three variants and would like to have this decided once and for all.

The answer depends on the numbering scheme. If you have:
Then I would use "Section 2.2", because it's the exact section number used for this section and it's much shorter. Consider referencing a "subsubsection":
If the numbering scheme omits the chapter number:
Then the cumbersome referencing scheme applies "Section 2 of Chapter 2" or "Second section in the second chapter".
