本发明揭露一种风力机机舱通风冷却装置及控制方法，其中，该机舱通风冷却装置包含：若干自然进气通风冷却模组，系配置于机舱两侧底部远离轮毂侧；若干自然排气通风冷却模组，系配置于机舱尾端上部两侧；一进气风扇强制通风冷却模组，系配置于机舱两侧底部靠近轮毂侧；一排气风扇强制通风冷却模组，系配置于机舱尾端上部；一控制器，系配置于控制箱内；以及一空气温度感测器，系配置于控制箱外。该通风冷却控制方法，利用空气温度感测类比讯号回馈至机舱内原风力机控制箱I/O模组及PLC控制方式，进行节能兼顾功能设计及控制。该控制器与风力机机舱内控制箱控制结合进行通风冷却控制；包含：一自然通风冷却方式运转；一自然通风冷却及排气风扇强制通风冷却方式运转；一自然通风冷却及排气风扇强制通风冷却及进气风扇强制通风冷却方式运转；以及一自然通风冷却及进气风扇强制通风冷却及排气风扇强制通风冷却方式运转。; several natural exhaust ventilation cooling module is disposed on the upper end of both sides of the nacelle , an inlet fan forced cooling module is disposed on the bottom sides of the nacelle near the hub side, an exhaust fan forced cooling module is disposed on the upper end of the central nacelle, a controller disposed on the control box, and an air temperature sensor is disposed outside of the control box. The ventilation and cooling control method is applied to detect air temperature sensing analog signal back to the original wind turbine control box I/O modules to do PLC control, being capable of energy-saving design and control function. The control method for the wind turbine controller and control box inside the nacelle combined for ventilation and cooling control, comprising a natural ventilation cooling operation mode, a natural ventilation cooling and ventilation exhaust fan forced cooling operation mode, a natural ventilation cooling operation and exhaust fan forced cooling operation and inlet ventilation cooling fan operation mode, as well as a natural ventilation cooling operation and inlet ventilation cooling fan operation and exhaust fan forced cooling operation mode. |
