The embodiment of the present invention provides a multi-connected air conditioner household metering and billing method and device, the method includes: obtaining the rated capacity of each indoor unit and the rated opening, actual opening and minimum opening of the expansion valve corresponding to the indoor unit ; Determine the proportion coefficient of the expansion valve opening, which is determined by the ratio of the difference between the actual opening and the minimum opening of the expansion valve to the difference between the rated opening and the minimum opening; according to the expansion The product of the proportion coefficient of the valve opening and the rated capacity of the corresponding indoor unit determines the first cooling / heating capacity of each indoor unit; Household metering is carried out in order to realize household fair billing based on the principle of energy-based billing.
Description
technical field [0001] The invention relates to the technical field of air-conditioning billing, in particular to a multi-connected air-conditioning household metering and billing method and device. Background technique [0002] At present, as a cooling / heating system with multiple terminals and variable refrigerant flow, the multi-connected air-conditioning system is widely used in small and medium-sized buildings because of its flexible control, energy saving, and low operating costs. In order to realize 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] Traditional household billing methods based on multi-connected air-conditioning systems include area apportionment method and time-based billing method. The area apportionment method is based on the area used by the user to evenly apportion the electricity b...
