Numerical researchof the microclimate in the restaurant hall using a VRF-system

The features of the microclimate formation in the restaurant hall are considered when using inflow exhaust ventilation and indoor units of the multi-zone VRF system. Calculation model grids are constructed taking into account the configuration features of the microclimate systems` elements. Numerical simulation of the thermal-air regime is performed in the STAR-CCM+ hydrodynamic package for various placement options and configurations of VRF-system devices. The most appropriate ways of the microclimate system arrangement with the use of two types of indoor units are identified. The analysis of the study results on the compliance of the microclimate parameters with the regulatory requirements is presented.
