An air conditioning unit energy-saving operation adjusting control system based on meteorological fluctuation prediction

Abstract

The application relates to the field of air conditioning regulation technology and discloses an air conditioning unit energy-saving operation regulation control system based on meteorological fluctuation prediction, which comprises a building heat response delay module, a pipe network residual cold quantity monitoring module, a variable frequency response phase control module and a meteorological mutation forced switching module. The building heat response delay module corrects a meteorological prediction disturbance curve according to a heat response delay parameter set. The pipe network residual cold quantity monitoring module determines the transient residual cold quantity accumulated in the chilled water pipe network. The variable frequency response phase control module calculates a physical delay span according to the corrected frequency modulation instruction and the transient residual cold quantity, and adjusts the action phase of the compressor. The meteorological mutation forced switching module monitors the outdoor temperature change rate to determine whether to suspend the delay state. According to the phase compensation of the meteorological disturbance and the quantitative utilization of the pipe network thermal inertia, the time deviation between the cold quantity supply and the building heat load demand is eliminated, and the unit operation oscillation is improved.
