Numerical Simulation on the Heat Dissipation of the Outdoor Unit in the Groove of High-Rise Building

In order to study the influence of heat dissipation outdoor unit in groove highrise building. Numerical simulation thermal environment a high-rise building is carried out. The results show that: When mean wind speed 2.7m/s, maximum inlet air temperature under full load condition about 43.3 °C, which 2 °C lower than that no condition. monsoon beneficial unit. hot rises, corner flow induced at side refuge layer. Due reverse pressure gradient, separation occurs, resulting blockage channel. flows through layer, expands suddenly due increase cross-section turbulent boundary layer separated. vortex region on upper Since and sides floor cannot be effectively dissipated, higher other floors, reduces working efficiency
