Abstract: There is described a controller and method for managing a flow unit. A measured full flow corresponding to a full open position of a flow control element of the flow unit is detected. A calibration nominal is established based on the measured full flow, and calibration relative flows are calculated based on the calibration nominal and calibration measured flows corresponding to calibration positions of the flow control element. Subsequent to calibration, an operation measured flow of the flow unit and an operation position of the flow control element are detected. A dynamic nominal is determined based on the operation measured flow and a particular calibration relative flow corresponding to the operation position of the flow control element. An operation relative flow and a relative flow setpoint are determined based, in part, on the dynamic nominal. The operation position of the flow control element is controlled based the operation relative flow and relative flow setpoint.

Abstract: Various embodiments of the teachings herein include a dynamic prediction control method for a precision air conditioner. An example method includes: generating a three-dimensional simulation model on the basis of a simulation template according to static information of a hardware configuration and layout of an application scene where the precision air conditioner is located, wherein the three-dimensional simulation model and a static model of the hardware configuration and layout of the application scene correspond to each other; running a simulation on the basis of a dynamic parameter of the precision air conditioner corresponding to the three-dimensional simulation model and establishing a correspondence relationship between the dynamic parameter and a simulation result using machine learning, so as to generate a proxy model; and predicting a temperature distribution and change of the application scene on the basis of the proxy model and real-time dynamic data of the precision air conditioner.

Abstract: A system and method for sampling air at multiple locations in a controlled environment. The system and method includes automatic adjustment of mass flow rates and duration of vacuum connections (either via time elapsed or indirectly by volume) based on rates set by an operator. Additionally, the system and method enables users to monitor and control aspects of the system via network-connected devices. Additionally, the system enable a vacuum pump to be disconnected from power in response to a physical emergency button, a software-based emergency stop button available on network connected devices, and an automatic power disconnection in response to an abnormal mass flow reading that could potentially impact the vacuum pump.
