Method for calculating electric charge of single refrigeration house of centralized refrigeration system

Abstract

The invention discloses a method for calculating electric charge of a single refrigeration house of a centralized refrigeration system. The method comprises the steps of collecting the opening time ofeach liquid supply electromagnetic valve in each refrigeration house of a centralized refrigeration system, and meanwhile recording the diameter of a tail end liquid supply pipeline in each refrigeration house; multiplying the opening time of each liquid supply electromagnetic valve by the diameter of the liquid supply pipeline at the corresponding tail end to obtain a numerical value; summing all the obtained numerical values to obtain the sum of the products of the opening time of all the liquid supply electromagnetic valves in the single refrigeration house and the diameters of the liquidsupply pipelines at the corresponding tail ends; obtaining the sum of the products of the opening time of all the liquid supply electromagnetic valves in each refrigeration house and the diameter of the corresponding tail end liquid supply pipeline in sequence; arranging an intelligent electric meter on a refrigerating unit and a condenser of the centralized refrigerating system, and meanwhile arranging an intelligent electric meter on a power supply bus of each refrigeration house; setting a time interval, and collecting the electric quantity of all the intelligent electric meters according to the time interval; calculating the electric quantity consumed by the single refrigeration house, and then obtaining the electric charge of the single refrigeration house.

Description

technical field [0001] The invention relates to the technical field of cold storage lease billing, in particular to a method for calculating the electricity charge of a single cold storage in a centralized refrigeration system. Background technique [0002] At present, many large-scale logistics cold storages use a centralized refrigeration system, that is, a set of refrigeration units provides cooling capacity for multiple cold storages, and the power consumption of each cold storage is divided equally among each cold storage according to the total power consumption of the cold storage. The cold storage system cannot calculate the power consumption of each cold storage. Since the power consumption factors of the cold storage are various, such as the amount of goods in and out of the warehouse, the temperature of the goods in and out of the warehouse, the number of times the door is opened, etc., the power consumption of each cold storage is also different. will be the same,...
