Ice storage air conditioner cooling load demand prediction distribution method and system

Abstract

The invention discloses an ice storage air conditioner cooling load demand prediction distribution method and system, and the method comprises the steps: building a target building moment cooling load prediction map, and dividing an ant colony into a plurality of sub-ant colonies; carrying out cold load demand prediction value search by utilizing each sub-ant colony, and sorting cold load demand prediction value search results of each sub-ant colony according to utility function values; obtaining ants corresponding to the cooling load demand prediction value search results tending to be in the middle in the cooling load prediction value search results according to the sorting result, updating pheromones of the ants to neighbor sub-ant colonies, and comparing the cooling load demand prediction values of the day to be regulated and controlled at the current moment searched by each sub-ant colony, outputting the optimal cooling load demand prediction value of the day to be regulated and controlled at the current moment; and performing curve fitting, and if the current moment is the last moment of the to-be-regulated day, obtaining a total cold load demand prediction value of the to-be-regulated day of the target building, thereby realizing cold load demand prediction distribution. The operation efficiency of the refrigerator is improved, and higher benefits are obtained.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration, and in particular relates to a method and system for predicting and allocating cooling load demand of an ice-storage air-conditioning system. Background technique [0002] Energy problems are becoming more and more serious, and energy conservation and emission reduction work has become the focus of various countries. Air conditioners are one of the most common energy-consuming equipment in buildings, accounting for about 60% of total power and energy consumption. In summer, the demand for electricity in public buildings is high, and the electricity consumption of air-conditioning systems again increases the peak load of the power grid, resulting in insufficient power supply at peak times, excess power at low valleys, and power grid failures such as power rationing and blackouts becoming more common. Ice-storage air conditioners use ethylene glycol aqueous solution as th...
