Sanchez and Lacombe have ever developed a lattice fluid theory based on a
well-defined statistical mechanical model. Taking the lattice fluid as a
candidate of dark energy, we investigate the cosmic evolution of this fluid.
Using the combined observational data of Type Ia Supernova (SNe Ia), Baryon
Acoustic Oscillations (BAO) and Observational Hubble Data (OHD), we find the
best fit value of the parameter in the model, $A = -0.3_{-0.1}^{+0.1}$. Then
the cosmological implications of the model are presented.
