摘要： An all-inclusive fluid flow device that can variably magnify differential pressure, measure, and control a flow of a fluid is described. Various procedures, including measuring, controlling, balancing, or calibration procedures can leverage a variably magnified differential pressure measurement. Differential pressure measurements can be measured across the fluid flow device such that a first pressure measurement is taken upstream of the fluid flow device while a second pressure measurement is taken downstream of the fluid flow device. Moreover, one or more of the various pressure measurements, and in particular the downstream pressure measurement, can be performed at stagnation zone where the flow has stagnated. Such can provide significant magnification and/or turndown capabilities and the magnification can vary based on a damper position and/or apertures dimensions.

摘要： A structure thermodynamic model, which models the physical characteristics of a controlled space, inputs a constraint state curve which gives constraints, such as temperature, that a controlled space is to meet; and outputs a state injection time series which is the amount of state needed for the controlled space to optimize the constraint state curve. The state injection time series curve is then used as input into an equipment model, which models equipment behavior in the controlled space. The equipment model outputs equipment control actions per control time (a control sequence) which can be used to control the equipment in the controlled space. Some embodiments train the models using training data.

摘要： Systems and methods of operating a two-pipe fan coil unit include, controlling the flow control valve and the fan using a controller, wherein the controller includes a heating control mode and a cooling control mode. The controller changes a position of the flow control valve from a first position to a second position, activates the fan to blow air across the heat exchanger coil and into the space of the building, and monitors a space temperature of the space. When the space temperature is determined to be increasing, the controller may determine that the building is in the building heating mode and sets the controller to the heating control mode, and when the space temperature is determined to be decreasing, the controller may determine that the building is in the building cooling mode and sets the controller to the cooling control mode.

摘要： An air conditioner includes an adapter including a control unit that controls the air conditioner using a learning model and a communication unit that communicates with a server device that generates the learning model on the basis of operation history data of the air conditioner. The adapter includes an acquisition unit, a determination unit, an erasing unit, and a transmission unit. The acquisition unit acquires the data every predetermined cycle from the air conditioner. The determination unit determines whether or not an amount of change between temporally continuous data of the data acquired by the acquisition unit is within a predetermined range. The erasing unit leaves at least one of the continuous data and deletes the other data in a case where the amount of change between the continuous data is within the predetermined range. The transmission unit transmits the data after being deleted to the server device.
