  The Bose-Einstein condensation and the liquid-gas first order phase
transition are studied in the interacting pion matter. Two phenomenological
models are used: the mean-field model and the hybrid model. Free model
parameters are fixed by fitting the lattice QCD data on the pion Bose
condensate density at zero temperature. In spite of some minor differences the
two model demonstrate an identical qualitative and very close quantitative
behavior for the thermodynamic functions and electric charge fluctuations. A
peculiar property of the considered models is an intersection of the
Bose-Einstein condensation line and the line of the first order phase
transition at the critical end point.
