Problems solved by technology

In the air conditioner power consumption acquisition method proposed in this technical solution, the server queries the power consumption by judging the air conditioner type and operating state to obtain the corresponding instantaneous power of the air conditioner, and then calculates the air conditioner within the target time according to the instantaneous power and operating state. Electricity, the instantaneous power obtained by this method is the rated instantaneous power in this operating state, not the instantaneous power generated in real time, so this method of calculating electricity consumption is not accurate

Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects of the invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

[0022] A method for calculating electric power of an air conditioner, comprising the steps of:

[0023] S1: Calculate the power of the outdoor unit except the AC fan: sample the input voltage and current through the PFC circuit, and the sampled values ​​are the instantaneous voltage U i and the instantaneous current I i , using formula I avg(t) = α·I sample (t) Compensate and correct the sampling current, where α is the current correction coefficient, I avg is the actual current equivalent waveform, I sample is the actual sampled current waveform; use the formula Obtain the power P of the outdoor unit except the AC fan 1 (If the outdoor fan is a DC fan, then P 1 Including the power of the outdoor DC fan), where N is the number of samples;

[0024] S2: ...

Abstract

The invention discloses a method for calculating the electric energy of an air conditioner. The method comprises the following steps: S1, calculating power of parts, except an alternating-current fan,of an outdoor unit by measuring a current correction coefficient; S2, calculating the power of an outdoor alternating-current fan by establishing a curve model; S3, calculating power of an indoor fanby establishing a curve model; S4, calculating electrical heating power of the indoor unit by establishing a curve model; S5, acquiring power of other parts of the air conditioner; and S6, calculating overall power and an overall electric energy consumption value. According to the invention, no electric meter needs to be set additionally; the electric energy amount is calculated by using instantaneous power generated in real time; the electric energy amount is calculated accurately; and the production and installation costs are saved effectively.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner power calculation method. Background technique [0002] At present, air conditioners have become commonly used electrical appliances. Among household appliances, the power consumption of air conditioners has always been relatively high. When users use air conditioners, they are more concerned about the power consumption of air conditioners. However, most of the methods for calculating power consumption of air conditioners on the market today are An external electric meter greatly increases the user's installation cost, or an additional power module is added to the air conditioner, which increases the manufacturer's air conditioner manufacturing cost. [0003] Even if there is a function that can calculate the power consumption of the air conditioner without adding an additional power metering module, most of them can only roughly estimate t...
