Air conditioner and control method and device of air conditioner

Abstract

The invention discloses an air conditioner and a control method and device of the air conditioner. The control method comprises the steps that first detecting data of an air conditioner humidity sensor when a fan is shut down is obtained, wherein the first detecting data comprises a first temperature and a first moisture content of the located environment at the moment that the fan is shut down; the first detecting data is used for correcting a relative humidity detected by the humidity sensor actually at the current time; and the air conditioner is controlled to operate according to the corrected relative humidity. According to the air conditioner and the control method and device of the air conditioner, the control method solves the problem of detection deviation of the humidity sensor due to refrigerating or heating shutting-down and influences of waste coldness and waste heat of an evaporator, the humidity detection is enabled to be closer to an actual value of the environment, automatic dehumidification and humidification functions of the air conditioner can operate normally, and the usage experience of users is effectively improved.

Description

technical field [0001] The present application relates to the technical field of air conditioners, in particular to an air conditioner and an air conditioner control method and device. Background technique [0002] At present, household air conditioners usually attach an indoor humidity sensor, such as a resistance-capacitance humidity sensor, to the evaporator of the indoor unit on the side facing the air intake grille, so as to obtain the indoor ambient temperature through the return air of the air conditioner. The distance between the measuring point of the humidity sensor evaporates The fins of the device are within 5cm. Among them, the resistance-capacitance humidity sensor is a sensor that uses the characteristics of the resistance value and capacitance value of the humidity sensor to change according to a certain law with the change of the ambient humidity to measure the humidity. [0003] However, due to the structural limitation of the air conditioner, the distance ...

AI Technical Summary

Problems solved by technology

[0004] The embodiment of the present application provides an air conditioner and an air conditioner control method and device to solve the problem that in the prior art, due to the small distance between the humidity sensor and the fins, when the cooling and heating are shut down, it is easy to cause the built-in temperature of the humidity sensor to deviate, and then The technical problem that leads to the deviation of humidity detection, thereby avoiding the problem of detection deviation of the humidity sensor caused by the shutdown of refrigeration and heating, the residual cold and residual heat of the evaporator, making the humidity detection closer to the actual value of the environment, and then making the air conditioner automatically dehumidify , Humidification function can work normally
