Embodiment Construction

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] figure 1 is a flowchart of an air conditioner control method according to an embodiment of the present invention;

[0027] Such as figure 1 As shown, the air conditioner control method includes:

[0028] Step S102, determining the average starting temperature Tm of the air conditioner. Wherein, the average starting temperature may be an annual average starting temperature. The following takes the annual start-up average temperature Tm as an example for description.

[0029] According to the use habits of room air conditioners in China and the distribution of start-up time, the annual start-up average temperature Tm is determined. (The following calculations are based on the cooling condition as an example. The calculation steps of the heating condition are the same as those of the cooling condition, so they will not be re...

Abstract

The invention provides a method and a device for controlling an air conditioner, and the air conditioner. The method for controlling the air conditioner is characterized by comprising the following steps of: s1, determining a power-on average temperature Tm of the air conditioner; s2, calculating the average load of reserved rooms according to the Tm; s3, calculating a rated cooling or heating frequency point, an intermediate cooling or heating frequency point, a frequency point corresponding to the average load and a maximum cooling or heating frequency point of the air conditioner under theTm; s4, determining curved lines of the output capacity of the air conditioner and the frequency and curved lines of the frequency and the energy efficiency under the power-on average temperature T, based on the frequency points; s5, calculating the optimal frequency section of the energy-to-efficiency ratio of the air conditioner according to the curved lines; and s6, controlling the air conditioner to work at the optimal frequency section of the energy-to-efficiency ratio by a controller of the air conditioner. By means of the method and the device disclosed by the invention, the power consumption of the air conditioner can be reduced.

Description

technical field [0001] The present invention relates to the field of air conditioners, and more specifically, to an air conditioner control method and device, and an air conditioner. Background technique [0002] With the development of technology and the improvement of people's living standards, people's demand for air conditioners is getting higher and higher, but the problem of relatively large power consumption of air conditioners is also becoming more and more serious. [0003] The existing inverter air conditioners do not take into account the different needs of different regions or the different usage habits of different regions, so most of the air conditioners cannot operate in the frequency band with the best efficiency of the system, which is not conducive to energy saving. [0004] Aiming at the problems in the related art that the power consumption of the air conditioner is relatively high and it is difficult to adapt to the usage habits of different regions, no ...
