In this paper, we extend the $\\Lambda$CDM+$r$+neutrino/dark radiation models by replacing the cosmological constant with the dynamical dark energy with constant $w$. Four neutrino plus dark energy models are considered, i.e., the $w$CDM+$r+\\sum m_\\nu$, $w$CDM+r + $N_{\\rm eff}$, $w$CDM+r + $\\sum m_\\nu$ + $N_{\\rm eff}$, and $w$CDM+r + $N_{\\rm eff}$ + $m_{\\nu,{\\rm sterile}}^{\\rm eff}$ models.
