Problems solved by technology
However, under the same refrigerant flow rate and indoor working conditions, after increasing the indoor air side air volume, the evaporation temperature will increase, the ratio of sensible heat to latent heat will increase, and the dehumidification capacity will decrease
Since the cooling operation of the air conditioner is accompanied by dehumidification, when the room temperature drops, the capacity output will gradually decrease, resulting in a slower cooling rate

The invention discloses an air conditioner and a control method and device thereof. The method comprises the steps of acquiring target temperature set by a user after the air conditioner is started, and acquiring indoor environmental temperature in real time; controlling the air conditioner to run with the preset maximum dehumidifying output or in the maximum dehumidifying mode, and recording thedehumidifying running time of the air conditioner; when the dehumidifying running range reaches preset time, controlling the air conditioner to switch to run in a refrigerating mode, and controlling the air conditioner to refrigerate based on the preset maximum output capacity; determining whether the difference between the current indoor environmental temperature and the target temperature is less than first preset temperature difference when the air conditioner runs to refrigerate; and if so, performing frequency-reduction control on the air conditioner. With the adoption of the control method, good temperature decrease effect can be realized within a short time; and moreover, the energy consumption can be reduced, so that the energy conservation is achieved.
Description
technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner control method, an air conditioner control device and an air conditioner. Background technique [0002] At present, the existing air conditioner control method mainly adopts the indoor temperature setting control method. Specifically, such as figure 1 As shown, the operating state of the air conditioner is adjusted according to the set indoor target temperature, or the difference between the set temperature and the indoor temperature, so that the temperature of the entire room reaches the set value. When the set temperature is reached, it will be shut down for processing, and if it is not reached, it will operate according to the set rules to ensure that the room temperature fluctuates in a small range around a set temperature center line. [0003] For a cooling system with variable flow, usually the user will give priority to a strong capacity output to obtai...
