    • A cooling system (28) cools an equipment room (20) wherein the equipment (24) is arranged in a plurality of rows (equipment rows) spaced to define a plurality of corridors (26) between respective rows. The cooling system has a plurality of air handling units (AHU) (32) arranged in a plurality of rows (AHU rows) (30). Each AHU row is respectively associated with a respective said equipment row. Each air handling unit has a cooling heat exchanger (40) and a fan (42) positioned to drive an airflow (500) across the cooling coil from an inlet (36) at one side of the row to an outlet (38) at the other side of the row. A plurality of cooling sources (90A-D) are respectively coupled to the cooling coils of a respective plurality of the AHUs, each row of AHUs including AHUs coupled to different such cooling sources.

    • A heating ventilation and air conditioning (HVAC) system includes a plurality of heating, ventilation and air conditioning (HVAC) units servicing a plurality of zones of a building. A plurality of controllers is connected to the plurality of HVAC units, each controller servicing one or more zones of the plurality of zones. The plurality of controllers include at least one first controller servicing at least one first zone that is powered off when the HVAC system is in a first operating mode and a second controller servicing a second zone of the plurality of zones that remains powered on when the HVAC system is in the first operating mode. The at least one second controller is operably connected to the at least one first controller to enable powering on of the first controller when an environmental condition in the second zone falls outside of a selected range.
    • 加热通风和空调(HVAC)系统包括为建筑物的多个区域提供服务的多个加热,通风和空调(HVAC)单元。 多个控制器连接到多个HVAC单元,每个控制器服务于多个区域中的一个或多个区域。 多个控制器包括至少一个第一控制器,该第一控制器服务于当HVAC系统处于第一操作模式时被关闭的至少一个第一区域,以及服务多个区域的第二区域的第二控制器,该区域在HVAC 系统处于第一个运行模式。 所述至少一个第二控制器可操作地连接到所述至少一个第一控制器,以在所述第二区域中的环境条件落在所选择的范围之外时能够使所述第一控制器上电。

    • A method and apparatus for controlling an HVAC system. The method may include receiving a fan speed signal from a fan control loop, and choosing among an independent mode, a first linked mode, and a second linked mode, depending on the fan speed signal. The method may also include providing a signal to a pressure control loop to reduce a speed of a supply air fan of an AHU, when the first linked mode is chosen. The method may further include providing a signal to a temperature control loop to decrease a speed of a heat exchange wheel, to decrease a flow rate of a heat exchange fluid to an evaporator coil, or both, when the second linked mode is chosen. The method may additionally include allowing the fan control loop to operate independently of the temperature and pressure control loops, when the independent mode is chosen.
    • 一种用于控制HVAC系统的方法和装置。 该方法可以包括从风扇控制环路接收风扇速度信号,并且根据风扇速度信号在独立模式,第一链接模式和第二链接模式之间进行选择。 当选择第一连接模式时,该方法还可以包括向压力控制回路提供信号以降低AHU的供气风扇的速度。 该方法可以进一步包括当选择第二链接模式时,向温度控制回路提供信号以降低热交换轮的速度,以降低热交换流体到蒸发器线圈或两者的流量。 当选择独立模式时,该方法还可以包括允许风扇控制回路独立于温度和压力控制回路工作。
