Embodiment Construction

[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Such as figure 1 As shown, in order to solve the above problems, an air conditioner control method is disclosed in the embodiment of the present invention. The control method is used to control the refrigerant heating module installed in the outdoor unit of the air conditioner under the condition of low temperature heating. Specifically, the control method includes the following steps:

[0036] First, when the air conditioner operates in the heating mode and meets the first preset condition, detect the outdoor ambient temperature, indoor ambient temperature and compressor exhaust temperature;

[0037] Secondly, obtain the user's set temperature;

[0038] Then, judging whether the outdoor ambient temperature, the difference between...

Abstract

The invention provides an air conditioner control method. The air conditioner control method is used for a refrigerant heating module of an air conditioner. The air conditioner control method comprises the following steps that an outdoor ambient temperature, an indoor ambient temperature and a compressor exhaust temperature are detected after the air conditioner operates in a heating mode and a first preset condition is met; a user set temperature is acquired; whether the outdoor ambient temperature, a difference value between the user set temperature and the indoor ambient temperature and thecompressor exhaust temperature meet a second preset condition is judged; and if yes, the refrigerant heating module is turned on. The turn-on of the refrigerant heating module is jointly controlled through three parameters of the outdoor ambient temperature, a user heating demand (obtained by the difference value between the user set temperature and the indoor ambient temperature) and the compressor exhaust temperature, the control of the refrigerant heating module is more accurate, and the refrigerant heating module cannot be turned on under the condition that refrigerant heating is not required, so that energy saving is further realized, and low-temperature heating capacity and energy efficiency are improved to the greatest extent.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner system and an air conditioner. Background technique [0002] When the air conditioner operates in the heating mode under low temperature conditions in winter, on the one hand, due to the low outdoor temperature, the evaporating temperature is low, and the refrigerant flow rate becomes smaller, resulting in a decrease in heating capacity; on the other hand, the coil of the condenser often Frosting will occur, and as the frost layer becomes thicker, the heating effect of the air conditioner will become worse and worse, resulting in the situation that the indoor heat cannot meet the needs of users. [0003] In the prior art, the air conditioner often installs an electric auxiliary heating device in the indoor unit to reheat the air to supplement the heating capacity. However, the power of the electric auxiliary h...
