Example Embodiment

[0044] The preferred embodiments of the present invention will be described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention. For example, although in this embodiment, when the indoor ambient temperature is less than the first temperature threshold and the difference between the set temperature and the indoor ambient temperature is greater than the preset difference, it is combined with first controlling the wind speed of the blower and then controlling the opening of the electronic expansion valve. However, the control sequence is not static, and those skilled in the art can adjust it, as long as the adjustment can meet the purpose of not turning on or turning on the electric heater. For example, under the condition that the above relationship is also satisfied, the opening ...

Abstract

The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioner. The control method of the air conditioner aims to solve the problems that anexisting air conditioner is high in energy consumption and poor in comfort when an electric heater is used for auxiliary heating. Therefore, the control method of the air conditioner comprises the following steps that the indoor environment temperature and the set temperature are obtained in heating mode; the size of the indoor environment temperature and the first temperature threshold value is compared, and/or the difference between the set temperature and the indoor environment temperature and the preset difference value are compared; according to the comparison result, the wind speed of anair supply fan and/or or the opening degree of a throttling element are selectively adjusted. By means of the control mode, the opening frequency and time of the air conditioner electric heater can be strictly controlled, compared with the prior art, the air conditioner has the advantages that the auxiliary heating of the electric heater can be started less, and the electricity consumption cost of a user is reduced while the comfort of the user is ensured.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method. Background technique [0002] An air conditioner is a device capable of cooling / heating a room. For example, in a cold winter, the air conditioner can increase the indoor temperature by heating and supplying air, thereby making people feel comfortable. [0003] In order to achieve fast and powerful heating of the air conditioner and improve user experience, the existing air conditioners are usually equipped with an electric heater. During the heating operation, when the indoor ambient temperature is lower than the set temperature, the electric heater is directly turned on to assist The air conditioner performs heating; when the indoor temperature reaches the set temperature, the electric heater is turned off. Although the indoor unit of the air conditioner uses an electric heater to assist heating, although rapid heating can be achieve...
