In a method for predicting an airflow rate of at least one air delivery device, a plurality of airflow rates through the at least one air delivery device at a plurality of airflow rates of at least one air moving device are received. A conditional probabilistic model is generated with the air moving device flow rates as inputs and the airflow rates through the at least one air delivery device as outputs. Moreover, the airflow rate of the at least one air delivery device is predicted from the conditional probabilistic model.

A method for agent-based operation of a robotic device. In the method, at least one condition is detected in various locations of a room with a plurality of sensors. In a plurality of agents associated with respective areas of the room, the plurality of agents being configured to control at least one condition in the respective associated areas, sensed data is received from at least one of the plurality of sensors. In addition, it is determined whether the received sensed data are outside of respective predetermined ranges, and information related to the sensed data in response to the sensed data being outside of the predetermined ranges is transmitted to the robotic device. In the robotic device, the information received from one or more of the plurality of agents is processed to determine whether components of a cooling system are to be manipulated to vary a characteristic of cooling fluid supplied to the various locations of the room.

摘要:
A system and method for reducing temperature variation among components in a multi-component system. In this respect, component temperatures are controlled to remain relatively constant (approximately within 5° C.) with respect to other components, while allowing for multiple fluctuating heat loads between components. A refrigeration system possessing a variable capacity (speed) compressor and a thermostatic expansion valve is utilized to control the flow of refrigerant through the refrigeration system. The temperatures of the components are reduced by metering the mass flow rate of the refrigerant cooling the components to compensate for the heat load applied to the refrigeration system. The temperature variation among the components is reduced by supplemental heaters independently providing heat to each respective component. In this regard, any relatively inactive, and therefore relatively cooler, component with respect to other components, may be heated by that component's respective supplemental heater, such that the temperature of the relatively inactive component is not reduced below the specified temperature range.
