For the recently introduced μ-deformed analog of Bose gas model (μ-Bose gas model) we study some thermodynamical aspects. Namely, we calculate total number of particles and, from it, the deformed partition function, both involving dependence on the deformation parameter μ. Such dependence of thermodynamic functions on the μ-parameter is at the core of modification of Bose gas model and arises through the use of new techniques given by us, the μ-calculus, an alternative to the well-known q-calculus (Jackson derivative and integral). Necessary elements of μ-calculus are first presented. Then, for high temperatures we obtain virial expansion of the equation of state and find five first virial coefficients, as functions of μ. At the other end, for low temperatures the critical temperature of condensation Tc^(μ) depending on μis found and compared with the usual Tc, and with the Tc^(p,q) of earlier studied p,q-Bose gas model. The internal energy, specific heat and the entropy of μ-Bose gas are also given, both for high and low temperatures. Features peculiar for the μ-Bose gas model are emphasized.
