Problems solved by technology

The portable sensing function has the following disadvantages: first, it increases the cost; second, if the remote control is placed too far away, or the infrared transmitter of the remote control is not aimed at the air conditioner, communication may fail, and the air conditioner controller will not receive the remote control The temperature signal sent; Third, if the remote control is placed near the heat source, the temperature sensed by the remote control will be inaccurate

Abstract

The invention relates to an accurate temperature control method of an air conditioner. The method comprises the following steps that: a) the air conditioner is controlled to be in a temperature calibration state; b) the air conditioner is controlled to be in a refrigerating or heating running mode; c) an indoor unit is controlled to run at any of strong wind speed, high wind speed, medium wind speed, low wind speed or mute wind speed; d) after the air conditioner runs for X hours, temperature T1 of a user activity area and wind inlet temperature T2 of the air conditioner are determined; e) the air conditioner memorizes the data of temperature difference delta T between T1 and T2 in a memory which is arranged on the control device of the air conditioner; and f) when the air conditioner runs in the same mode and at the same wind speed at a later stage, the temperature of the user activity area is automatically controlled according to the temperature difference delta T determined at the step e, user set temperature TS and the wind inlet temperature detected by the air conditioner. By actually determining the temperature of the user activity area and the wind inlet temperature of the air conditioner and accurately calculating the temperature difference between the temperature of the user activity area and the wind inlet temperature at the installation position of the air conditioner, the air conditioner can accurately control the temperature of the user activity area and users can enjoy the most comfortable temperature.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a method for accurately controlling the temperature of the air conditioner. Background technique [0002] In actual use, the installation position of some air conditioners is relatively high, resulting in the inconsistency between the temperature of the location of the air conditioner and the temperature of the user's activity area in the room. The air conditioner controls the temperature of the room according to the temperature of the location, and cannot accurately control the temperature of the user's activity area. . At present, there are two ways to solve this problem. The first is to add fixed temperature compensation to the existing air conditioner temperature control algorithm. For example, Chinese Patent Document No. CN101769583A disclosed a compressor control temperature deviation compensation function on July 7, 2010. The air conditioner control method is characterized in that it...
