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 and the outdoor fan is an AC When the fan is tapped, because the current and voltage signals cannot be collected, it is difficult to detect the power of the 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 detection method and device for an air conditioner and the air conditioner. The method includes the steps that a voltage instantaneous value of an outdoor unit and a current instantaneous value of a compressor are acquired through an outdoor controller and active power of the compressor is calculated; a voltage effective value of the outdoor unit is calculated through an outdoor controller and sent to an indoor controller; the temperature of an outdoor heat exchanger and the outdoor environment temperature are acquired through the outdoor controller and a first power estimation model function is established for estimating the operation power of an outdoor fan; the rotation speed of a motor of an indoor fan, the angle of air guide strips of the indoor unit, the temperature of the indoor heat exchanger, the indoor environment temperature and the indoor environment humidity are acquired through the indoor controller, and a second power estimation model function is established for estimating the operation power of an indoor fan; the indoor controller conducts modeling according to a first input variable so as to estimate the operation power of a PTC; and the total power of the air conditioner is acquired and integrated, so that the power consumption is acquired. By the adoption of the method, the power consumption of the air conditioner can be accurately acquired without adding any 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...
