Environmental Control Systems (ECS) are designed to manage and maintain the environmental conditions within a specific area, such as a building or vehicle. These systems regulate factors like temperature, humidity, and air quality to ensure a comfortable and safe environment for occupants. ECS can include heating, ventilation, and air conditioning HVAC systems, as well as air filtration and humidity control mechanisms. In aerospace applications, ECS plays a crucial role in maintaining the right conditions for crew and equipment. For example, in aircraft, ECS ensures that the cabin remains pressurized and at a suitable temperature during flight. This is essential for the safety and comfort of passengers and crew, as well as the proper functioning of onboard systems.
