Abstract

The embodiment of the invention discloses an electricity quantity distributing method of a frequency conversion multi-connected central air-conditioning machine set for accurately calculating external shared inner electricity quantity shared to indoor machines at a start-up state by an outdoor machine and actual electricity using quantity of the indoor machines. The method of the embodiment of the invention comprises the following steps of: acquiring electricity meter number within the time delta T, wherein the delta T is greater than 0; calculating the theory consumed electricity quantity of each indoor machine within the time delta T under a working state, and the total theory consumed electricity quantity of all indoor machines within the time delta T; calculating the external shared inner electricity quantity of each indoor machine at the start-up state by the outdoor machine within the time delta T according to the electricity meter number, the theory consumed electricity quantity and the total theory consumed electricity quantity; and calculating other shared electricity quantities and the actual electricity using quantity of the indoor machines.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method for distributing electric power of frequency conversion multi-connected central air conditioning units. Background technique [0002] Frequency conversion one drag multi-variable refrigerant flow central air conditioning system (referred to as frequency conversion multi-connected air conditioning system) is a refrigerant circulation system composed of one outdoor unit and several indoor units. It is a form of variable refrigerant flow air conditioning system. A refrigerant-type air-conditioning system is widely used in schools, hospitals, office buildings, hotels and other buildings. Through centralized management, it charges by room and household. [0003] At present, the room and household billing algorithm of frequency conversion multi-connected air-conditioning system basically adopts rough estimation. When each indoor unit is started, the power consumption...
