Problems solved by technology
In this method, since the power of the indoor unit is an estimated value, especially when the electric auxiliary heat is started, the power of the electric auxiliary heat is relatively high and the fluctuation is relatively large. At the same time, when the indoor fan is an AC PG fan, it cannot be collected Its current and voltage signals, so there will be deviations in the power of the indoor fan, so that the accuracy of the calculated power and power consumption of the air conditioner is relatively low, and it is difficult to meet the actual needs of users

The invention discloses a power consumption detecting method and device for an air conditioner and the air conditioner. The method comprises the steps that an outdoor controller obtains the voltage instantaneous value and the current instantaneous value of an outdoor unit, and active power of an outdoor draught fan and active power of a compressor are calculated; the outdoor controller calculates the voltage effective value of the outdoor unit and sends the voltage effective value to an indoor controller; the indoor controller obtains the rotating speed of a motor of an indoor draught fan, the angle of indoor unit air guiding strips, the temperature of an indoor heat exchanger, the indoor environment temperature and the indoor environment humidity, and the running power of the indoor draught fan is estimated by establishing a power estimation model function; the indoor controller carries out modeling on the running power of a PTC with the temperature of the indoor heat exchanger, the running power of the indoor draught fan and the voltage effective value of the outdoor unit as a first input variable, and therefore the running power of the PTC can be estimated; and the total power of the air conditioner is obtained, and integral operation is carried out on the total power so as to obtain the power consumption of the air conditioner. According to the method, the power consumption of the air conditioner can be accurately obtained without adding hardware cost.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to a method and device for detecting power consumption of an air conditioner, and an air conditioner. Background technique [0002] With the popularization of air conditioners and the increasing awareness of energy saving and emission reduction of users, users are more and more concerned about the power and power consumption of the air conditioner in the process of using the air conditioner. Feedback to users has become the development direction of air conditioners. In the related art, the power and power consumption of the air conditioner are mainly obtained through the following two methods. [0003] 1) Obtain the power and power consumption of the air conditioner by adding power detection hardware: for example, add a dedicated power detection module at the input end of the air conditioner, or add a voltage and current sensor at the input end of the air cond...
