  text: We investigate superradiant enhancements in the refrigeration performance
    of a set of N three-level systems that are collectively coupled to a hot and a
    cold thermal reservoir and are additionally subject to collective periodic (circular)
    driving. Assuming the system-reservoir coupling to be weak, we explore the regime
    of stronger periodic driving strengths by comparing collective weak driving, Floquet-Lindblad,
    and Floquet-Redfield master equations. We identify regimes where the power injected
    by the periodic driving is used to pump heat from the cold to the hot reservoir
    and derive analytic sufficient conditions for them based on a cycle analysis of
    the Floquet-Lindblad master equation. In those regimes, we also argue for which
    parameters collective enhancements like a quadratic scaling of the cooling current
    with N can be expected and support our arguments by numerical simulations.
