空气处理单元（Air Handling Unit）是一种用于处理空气的设备，通常用于空调和通风系统。它负责将空气吸入，进行冷却、加热、过滤、加湿等处理，然后将处理后的空气输送到室内或外部环境中。
以下是一篇关于空气处理单元的英文范文：
Air Handling Unit (AHU) is a crucial component of an air conditioning system. It manages the flow of air into and out of a building, ensuring that the indoor environment is comfortable and healthy.
An AHU typically includes a blower, cooling and heating coils, filters, and possibly a humidistat or moisture meter. The blower forces air through the filters and coils, where it can be cooled or heated, depending on the system configuration. The AHU also includes a controller that monitors the airflow, humidity, and temperature, and adjusts the system's components accordingly.
In a central air conditioning system, an AHU receives air from various parts of the building and distributes it to the various rooms. It also extracts air from the rooms and returns it to the cooling and heating system for further treatment.
Air handling units are commonly used in commercial and residential buildings, where they provide a comfortable environment for occupants and ensure that the building operates efficiently and cost-effectively.
空气处理单元（Air Handling Unit）是一种用于处理和输送空气的设备，通常用于空调和通风系统。它包括风扇、过滤器、加热器、冷却器等组件，用于调节室内空气的温度、湿度和洁净度。在英文范文当中，air handling unit可能会出现在关于空调系统、建筑环境、能源工程等领域的文章中，用于描述空气的处理和输送过程。
“Air handling unit”是空气处理单元的意思。AIR HANDLING UNIT 在制冷系统中，主要是负责空气的新风处理，包括新风和回风的送风处理。AIR HANDLING UNIT 的主要部件有：各种风机、过滤器、表冷器、加热器、加湿器、送风机等。
在英文范文中的最新变化可能涉及到其使用语境和表达方式的多样化。例如，它可能被赋予更多的环保或可持续性元素，如强调能源效率、减少污染和资源消耗等。同时，随着全球对健康和舒适环境的需求增加，Air handling unit可能会与相关术语如空气质量、室内空气污染等相结合，以更全面地描述和解释其在现代建筑环境中的作用。
