  In a simple model it is demonstrated that the neutron star surface
temperature evolution is sensitive to the phase state of the triplet superfluid
condensate. A multicomponent triplet pairing of superfluid neutrons in the core
of a neutron star with participation of several magnetic quantum numbers leads
to neutrino energy losses exceeding the losses from the unicomponent pairing. A
phase transition of the neutron condensate into the multicomponent state
triggers more rapid cooling of superfluid core in neutron stars. This makes it
possible to simulate an anomalously rapid cooling of neutron stars within the
minimal cooling paradigm without employing any exotic scenarios suggested
earlier for rapid cooling of isolated neutron star in Cassiopeia A.
