Cockpit pressure adjusting system and adjusting method, cockpit and working machine
The invention relates to a pressure adjusting system for a cockpit, the cockpit comprising the pressure adjusting system, a working machine comprising the pressure adjusting system, and a pressure adjusting method for the cockpit. Wherein the cockpit is provided with an air conditioner, the pressure adjusting system comprises an air supply device, a temperature sensor and a controller, the air supply device supplies air outside the cockpit into the cockpit to ensure positive pressure in the cockpit, and an adjusting valve is arranged in the air supply device; the controller is configured to judge whether to automatically adjust the opening degree of the adjusting valve or not according to the difference value between the measured value of the temperature sensor and the preset comfortable temperature under the condition that the air conditioner is turned on. According to the air supply device, the air supply amount of the air supply device is reduced under the condition that rapid heating/cooling is needed, the refrigerating/heating efficiency of the air conditioner is optimized on the premise that the positive pressure requirement in a cockpit is met, and energy loss is reduced. In addition, a pressure sensor can be arranged in a cockpit, so that the opening degree of the regulating valve is reduced on the premise that the positive pressure requirement is met.
本发明涉及一种用于驾驶舱的压力调节系统及包括其的驾驶舱和作业机械，以及一种驾驶舱压力调节方法。其中驾驶舱设置有空调，所述压力调节系统包括送风装置、温度传感器以及控制器，其中送风装置将驾驶舱外空气送入驾驶舱以保证驾驶舱内的正压，并且送风装置中设置有调节阀；控制器被配置成在所述空调打开的情况下，根据温度传感器的测量值与预定舒适温度之间的差值来判断是否自动调节所述调节阀的开度。本发明实现了在需要快速升温/降温的情况下减小送风装置的送风量，在满足驾驶舱内正压需求的前提下优化了空调的制冷/制热效能，降低了能源损耗。本发明还可在驾驶舱内设置压力传感器，以保证在满足正压力需求的前提下才减小调节阀的开度。
