Control method, device and air-conditioning device for air-conditioning device

Abstract

A method and device for controlling an air conditioning device, and an air conditioning device. An air outlet is arranged at an indoor unit of the air conditioning device. An air channel in communication with the air outlet is provided therein with a fan and a purification unit used to purify an air flow output from the fan. The air outlet is further provided with a first sensor used to detect an air velocity. The method comprises: controlling a first sensor to detect an outlet air velocity of an air flow after the air flow has passed through a purification unit; determining, for the purification unit, and according to a difference between the outlet air velocity and a reference air velocity, an air amount or an air velocity loss value; and adjusting a rotation speed of the fan according to the air amount or the air velocity loss value. The method enables a rotation speed of a fan to be automatically adjusted according to an air amount or an air velocity loss value, thereby adjusting the amount of air purified, ensuring purification efficiency and performance. Moreover, the rotation speed of the fan changes in accordance with the loss value, thereby preventing high energy consumption as a result of continuous rotation of the fan at a higher speed, and effectively reducing energy consumption.

Description

technical field [0001] The present application relates to the technical field of household appliances, in particular to a control method and device for an air conditioning device and the air conditioning device. Background technique [0002] With the improvement of people's living standards, air conditioning devices such as air conditioners and air purifiers gradually appear in thousands of homes and offices. At present, the gas can be purified by the air conditioning device to improve the comfort of the environment in the space where the air conditioning device is located. [0003] However, the applicant found that in actual use, the existing air conditioning device operates at a fixed fan speed. When the filter screen is dirty or blocked or other functional filters with low or high wind resistance are replaced, in this way, If the purification air volume of the air conditioning device cannot be effectively adjusted, the purification effect will not be guaranteed, or energ...

Problems solved by technology

Moreover, the speed of the fan changes with the change of the loss, which can avoid the situation that the fan has been running at a high speed, resulting in high energy consumption, can effectively reduce energy consumption, and is used to solve the problem that the air conditioning device cannot be adjusted in the prior art. The technical problem that the purification air volume cannot guarantee the purification effect
