This work is devoted to the study of heat and mass transfer apparatus of indirect- evaporative type. This device consists of two channels, in one of which the processes of heat and mass transfer occur. This scheme is known in the literature as the By-pass scheme. Numerical studies of laminar flow and heat and mass transfer are carried out with variations in the input parameters (Reynolds number Re=100, temperature T 0 = 26 ÷ 32 °C and relative humidity φ 0 = 40 ÷ 70 %). The resulting cooling effect in such a heat and mass transfer apparatus can be quite high and comparable with traditional air conditioning schemes, including steam-compression refrigeration machines.
