The invention belongs to the field of power facilities and particularly relates to a power distribution room with cooling and dehumidifying functions. The power distribution room comprises a foundation and a power distribution room body arranged on the upper portion of the foundation. The power distribution room body comprises vertical columns arranged at the end corners of the foundation and wallboards, wherein the wallboards and the vertical column are arranged in a matched mode. The power distribution room body further comprises an overhauling door and a ventilation window. The foundation comprises an enclosing wall and a bottom plate arranged at the top of the enclosing wall and is internally provided with a dehumidifying mechanism. According to the power distribution room with the cooling and dehumidifying functions, by utilizing the dehumidifying mechanism arranged on the lower portion of the bottom plate, the influence of the humid environment on the power distribution room is effectively reduced; each wallboard comprise a main wallboard body and a wind blocking wallboard body which are arranged in the front-rear direction, so that damage of wind force to a power distribution station is reduced effectively; and meanwhile traditional heat dissipation fans are changed into a suction fan and a blower, and the suction fan and the blower are arranged in a matched mode, so that the heat dissipation effect is improved effectively, and accordingly the purposes of cooling, dehumidifying and wind resisting are achieved.
