We have explored the phase behavior of a set of water-like models in slit pores of nanoscopic dimensions. The interaction between water and pore walls mimics the graphite surface. A version of density functional method is used as theoretical tools. The fluid models are adopted from the work of Clark et al. [Mol. Phys., 2006 104, 3561]. They reproduce the bulk water vapor-liquid coexistence envelope adequately. Our principal focus is on changes of topology of the phase diagram of confined water and establishing trends of behavior of the crossover temperature between condensation and evaporation on the strength of water-graphite interaction potential. Growth of the water film on the pore walls is illustrated in terms of the density profiles. Theoretical results are discussed in context of computer simulation findings for water models in pores.

Key words: associating fluids, density functional theory, wetting, adsorption, water models
