Constant air volume control method of air conditioner

Abstract

The invention provides a constant air volume control method of an air conditioner, and belongs to the field of constant air volume control of the air conditioner indoor unit. The key point of the technical scheme is as follows, the running parameters of a motor of the air conditioner indoor unit at different running speeds of the fan in the factory debugging process are acquired, and the standardvalue of the running power is calculated; in the using process of the air conditioner, the running parameters of the motor of the air conditioner indoor unit are acquired in real time, and the corresponding real-time running power value is calculated; the running power standard value and the real-time running power value are compared; if the real-time running power value is smaller than the running power standard value, the rotating speed of the fan is increased; when the rotating speed of the fan is increased, the running power standard value can be reached if the real-time running power value is increased, the rotating speed is increased to the corresponding rotating speed, and if the rotating speed of the fan is increased to the maximum rotating speed, the real-time running power valuecan still not reach the operating power standard value, and then alarm information is sent out.

Description

technical field [0001] The invention relates to an air conditioner control technology, in particular to a technology for constant air volume control of an air conditioner. Background technique [0002] At present, the indoor units of air conditioners are equipped with filter screens, and the dust is deposited on the filter screens after being filtered. Users need to clean them regularly, otherwise bacteria will easily breed and cause secondary pollution, and dust will affect the air supply volume and air supply distance of the indoor units. Thus affecting the cooling and heating effect of the air conditioner. At the same time, the heat exchanger of the indoor unit is also prone to dust collection, and the dust on the heat exchanger will also affect the air supply volume of the indoor unit, thereby affecting the cooling and heating effects of the air conditioner. [0003] In the patent application with the application number CN104990202A, a method for controlling dirty block...

Problems solved by technology

[0009] The purpose of the present invention is to provide a method for controlling the constant air volume of an air conditioner, which solves the problem that the air volume of the indoor unit becomes smaller due to the reduction of the air density and the decrease of the air flow in the application of the current air conditioner at a high altitude, which causes the power to drop or the filter screen to be dirty and blocked. The problem of uneven air volume
