In case somebody stuck with the same problem I found the solution.
If you edit productContent.php and change line
echo str_replace("\n","<br />",get_the_content());
to
do_shortcode(str_replace("\n","<br />",get_the_content()));
shortcodes will be visible in product description.

Thanks for answer. It’s making me closer to solve the problem.
But as I don’t know anything about programming I have no clue what code should look like when I insert it to shortcodes.php file – as I understand I need to edit this file.

Sorry for trouble.
