Embodiment
[0052] see figure 1 , this embodiment provides a static pressure detection method, which is mainly used to detect the target static pressure value of the air duct machine 13. The static pressure detection method provided by this embodiment can improve the detection accuracy of the target static pressure value, thereby realizing the air duct Machine 13 constant air volume control.
[0053] The static pressure value refers to the magnitude of the pressure that the air duct machine 13 is subjected to when it is stationary or moving in a straight line at a uniform speed. The static pressure value of the same air duct machine 13 is different in different working environments. The static pressure value in the working environment is also different.
[0054] The static pressure detection method provided in this embodiment is mainly applied to the air conditioner 10, the air conditioner 10 includes a controller 11, a current detector 12 and an air duct machine 13, the current detector...

The invention provides a static pressure detection method, device and air conditioner, and relates to the technical field of air conditioners. The static pressure detection method includes: responding to the start-up command, controlling the air duct machine to run at a preset speed corresponding to the set static pressure value; obtaining the three-phase current value when the air duct machine runs at the preset speed; calculating the air duct machine according to the three-phase current value. The torque current value of the air duct machine; the detected static pressure value of the air duct machine calculated according to the torque current value; the target static pressure value of the air duct machine is calculated according to the detected static pressure value. In the embodiment of the present invention, since the torque current value of the air duct machine is only related to the load, the torque current value is calculated according to the three-phase current value, and the target static pressure value can be calculated by using the torque current value to ignore the AC voltage for static pressure interpretation To improve the accuracy of the target static pressure value, so as to achieve the constant air volume control of the duct machine.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a static pressure detection method and device and an air conditioner. Background technique [0002] With the continuous improvement of people's living standards, air conditioners have become an indispensable electrical appliance in the family. At the same time, people's requirements for the performance of air conditioners are also gradually increasing. During the actual operation of the current air conditioners, the speed of the internal motor is fixed in the three gears of high, medium and low. However, due to the different static pressure of the environment used by each user, the final output Air volume varies. However, the detection accuracy of the static pressure value in the prior art is relatively low. Contents of the invention [0003] The problem solved by the invention is how to improve the detection accuracy of the target static pressure value. [0004] In...
