Water-cooled central air conditioner terminal baffle metering device and system

Abstract

The application discloses a water-cooled central air conditioner terminal baffle metering device and system, the device comprises a control unit and a reference air conditioning unit, a sensing detection unit, a user interface unit and a working condition adjusting unit connected with the control unit; the control unit takes four scalars, i.e. the chilled water supply flow of the host computer, the supply and return water temperature difference, the current temperature and humidity of the room, and a vector composed of all terminal baffle opening state values as input, takes the cooling capacity of the terminal baffle per unit time as output, and establishes a neural network; the room is taken as a heat load, the reference air conditioning unit and the terminal baffle respectively generate refrigeration under the same working condition, the calibrated reference air conditioning unit is taken as a cooling capacity reference sample of the terminal baffle, and the trained network is used to predict the cooling capacity of the terminal baffle under the current working condition. The application can dynamically reflect the cooling capacity change of the terminal baffle, improves the metering precision compared with the method of only detecting the terminal, provides a basis for charging according to the cooling capacity, and is helpful to the energy saving and utilization of the air conditioner.
