Household metering and charging method and device for multi-split air conditioner

Abstract

The embodiment of the invention provides a household metering and charging method and device for a multi-split air conditioner. The method comprises the steps that operating parameters of the multi-split air conditioner are obtained; the operation parameters are input into a data mining model, indoor unit refrigerating/heating capacity, output by the data mining model, corresponding to the indoorunit of each household is obtained, and household metering of the multi-split air conditioner is conducted, wherein the operation parameters at least comprise the expansion valve opening degree, the rated capacity and the return air temperature of the indoor unit, and the data mining model is obtained by taking the operation parameters as samples and taking indoor unit refrigerating/heating capacity corresponding to the operation parameters as labels through training. The method and device are easy and convenient to operate and high in universality, the indoor unit refrigerating capacity/heating capacity of each household can be conveniently and comprehensively determined according to the multiple operation parameters of the multi-split air conditioner, and therefore household-based metering can be accurately conducted on the indoor unit refrigerating capacity/heating capacity of each household, and household-based fair charging can be achieved on the basis of the energy-type chargingprinciple.

Description

Technical field[0001]The invention relates to the technical field of air-conditioning billing, in particular to a multi-line air-conditioning household metering and billing method and device.Background technique[0002]At present, as a multi-terminal, variable refrigerant flow refrigeration / heating system, the multi-line air-conditioning system has flexible control, energy saving, and low operating cost. It is increasingly widely used in small and medium-sized buildings. In order to achieve the measurement and management of building energy consumption, it is particularly important to measure the performance of the multi-connected air conditioning system and the measurement of energy consumption.[0003]The traditional household billing methods based on multi-line air conditioning systems include area allocation method and time-based billing method. The area apportionment method is based on the user's use of the area to share the electricity billing of the air conditioning unit. However,...
