The invention discloses an air-intake control device for a condensation module of a cooling tower. The air-intake control device comprises pressure sensors (103, 104, 108), air pressure sensors (101, 102), a louver type air-intake device (105), a PLC controller (106), a push-pull rod electric device (107), a cooling tower fan (109) and a condensation module (110). The air pressure sensors are used for measuring pressure P1 and pressure P2 on two sides of each blade of a louver and measuring pressure P3 of a wet hot air outlet and pressure P4 of a dry cold air outlet. Pressure and air pressure signals are inputted into a PLC controller for determining an adjusting direction of cold air rate. Based on the relation of P1 and P2, a power source circuit of the electric device is controlled, and a motor is controlled to turn, start and stop. A push-pull rod is controlled to move by means of a mechanical conveyer so that directions of the blades are adjusted to be in an optimal air-intake state. The pressure sensors are arranged above a mixing segment of the condensation module. Pressure P5 at the mixing segment is conveyed to the PLC controller. The fan is controlled to operate by outputting signals. The air-intake control device for the condensation module of the cooling tower helps to achieve automated control of over air-intake amount of the condensation module of the cooling tower and the cooling tower fan.
