You need to refedine or patch \@acf. The following example replaces the space with dots:

\documentclass{article}
\usepackage{acronym,etoolbox}

\makeatletter
\patchcmd\@acf{\nolinebreak[3] }{\nolinebreak[3]\ldots}{}{}
\makeatother

\begin{document}

\ac{foo}

\begin{acronym}
\acro{foo}{long description of foo}
\end{acronym}

\end{document}


Replace \ldots in the above code with whatever space you want.

If you also want to change the appearance in PDF bookmarks you also need to redefine/patch \acfa.
