热管是一种长而密封的翅片管，内充制冷剂。管子略微倾斜，一端在室外进气口，另一端在排气口。在加热应用中，制冷剂在较低的一端在温暖的排气中蒸发，蒸汽在较冷的室外空气中向较高的一端上升，在那里它放弃蒸发热并冷凝。吸管将液态制冷剂带回热端，循环在热端重复。热管不需要能量输入。对于冷却，通过将管道倾斜到另一个方向来反转该过程。控制装置可以是气动、电动、电子、数字或组合。在每个系统上使用独立的控制回路可以实现令人满意的控制。控制系统可根据区域的要求调整中央系统的运行，从而达到大的运行效率和舒适度。这样的系统可以节省足够的运营成本，以便在短时间内自行支付费用。空气处理系统和区域的控制装置是由设计建筑的建筑师、工程师或团队专门为建筑设计的。控制装置通常安装在作业现场。终端装置控制装置通常在工厂安装。锅炉、热泵和屋顶机组通常与专为该机组设计的工厂安装控制包一起出售。

A heat pipe is a long, sealed, finned tube charged with a refrigerant. The tube is tilted slightly with one end in the outdoor air intake and the other end in the exhaust air. In a heating application, the refrigerant vaporizes at the lower end in the warm exhaust air, and the vapor rises toward the higher end in the cool outdoor air, where it gives up the heat of vaporization and condenses. A wick carries the liquid refrigerant back to the warm end, where the cycle repeats. A heat pipe requires no energy input. For cooling, the process is reversed by tilting the pipe the other way. Controls may be pneumatic, electric, electronic, digital, or a combination. Satisfactory control can be achieved using independent control loops on each system. Maximum operating efficiency and comfort levels can be achieved with a control system which adjusts the central system operation to the demands of the zones. Such a system can save enough in operating costs to pay for itself in a short time. Controls for the air handling system and zones are specifically designed for a building by the architect, engineer, or team who designs the building. The controls are usually installed at the job site. Terminal unit controls are typically factory installed. Boilers, heat pumps, and rooftop units are usually sold with a factory-installed control package specifically designed for that unit.
