Problems solved by technology

In the prior art, the energy consumption of multi-connected air conditioners is mainly concentrated in indoor units and outdoor units. Due to the large number and wide distribution of indoor units, the statistics of energy consumption are relatively cumbersome. For example, currently, an electric meter is installed around each indoor unit. The power consumption is counted through the electric meter corresponding to each indoor unit, but this method of counting power consumption not only has a high cost of statistical equipment, but also the installation operation is complicated and cumbersome, prone to errors, and difficult to operate in actual engineering
[0003] For the above problems, no effective solution has been proposed

Abstract

The invention discloses a metering method, device and system for electric charge of an air conditioner. The metering method comprises the following steps that electric quantity data recorded by a target single electricity meter is acquired; based on electric quantity data, the total power consumption of a multi-split air conditioning system in a pre-designed time period is calculated; the outdoorunit power consumption needing to be borne by a target indoor unit with the electric charge to be calculated in the multi-split air conditioning system and the motor power and the running duration ofthe target indoor unit are determined; based on the total power consumption of the multi-split air conditioning system, the outdoor unit power consumption needing to be borne by the target indoor unitand the motor power and the running duration of the target indoor unit, the apportionment electric quantity of the target indoor unit is determined; and based on the apportionment electric quantity of the target indoor unit and the electricity price, the electric charge of the target indoor unit in the pre-designed time period is calculated. According to the metering method, device and system, the technical problem of relatively high equipment cost for counting the power consumption of the multi-split air conditioner in the related art is solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a method, device and system for measuring electricity charges of air conditioners. Background technique [0002] In related technologies, many buildings, shopping malls, factories and other environments use multi-connected air conditioners to adjust the environment. For example, multi-connected air conditioners are used to adjust temperature and humidity; As a large energy consumer, multi-connected air-conditioning systems generally include multiple indoor units. The operating conditions of each indoor unit are different, and their power consumption is also different. How to measure, apportion and apportion accuracy the power consumption of multi-connected air-conditioning systems , Rationality has always attracted the attention of the industry and users. In the prior art, the energy consumption of multi-connected air conditioners is mainly concentrated in indoo...
