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, so it is difficult to accurately estimate the power of the indoor unit
At the same time, when the outdoor fan is an AC fan, since its current and voltage signals cannot be collected, there will be deviations in the power of the outdoor unit, 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 needs of users.

The invention discloses a method and device for detecting the electric consumption of an air conditioner and the air conditioner. The method comprises the following steps: an outdoor controller obtains an instantaneous voltage value of an outdoor machine and an instantaneous current value of a compressor and calculates the active power of the compressor; the outdoor controller calculates an effective voltage value of the outdoor machine and transmits the effective voltage value to an indoor controller; the outdoor controller obtains the temperature of an outdoor heat exchanger, the temperature of the outdoor environment and the effective voltage value and estimates the operating power of an outdoor fan through modeling; the indoor controller obtains currents of a d shaft and a q shaft of the indoor motor, calculates the voltages of the d shaft and the q shaft, and calculates the power of the indoor fan according to the currents and the voltages of the d shaft and the q shaft; the indoor controller obtains the temperature of an indoor heat exchanger and estimates the operating power of PTC by using the temperature of the indoor heat exchanger, the power of the indoor fan and the voltage effective value of the outdoor machine as first input variables; the total power of the air conditioner is obtained so as to obtain the electric consumption of the air conditioner. By the method disclosed by the invention, the electric consumption of the air conditioner can be obtained without the increasement of hardware cost.
Description
technical field [0001] The invention relates to the technical field of air conditioners, 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 air conditioners in the process of using air conditioners. Feedback to users has become the direction of air conditioner development. In related technologies, 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 conditioner to detec...
