Abstract

An embodiment of the invention discloses an air conditioner, an air conditioner control method and an air conditioner control device. The air conditioner control method includes: detecting the environment temperature of the air conditioner; determining a target temperature range of the environment temperature, and acquiring a first target preset time and a first target preset temperature corresponding to the target temperature range; continuously acquiring target temperatures on the air conditioner within the first target preset time, wherein the target temperatures at least include a plurality of temperatures detected from fins of an outdoor unit of the air conditioner; judging whether a minimum value in the target temperatures is smaller than or equal to the first target preset time or not; under the condition that the minimum value in the target temperatures is smaller than or equal to the first target preset time, controlling the air conditioner to defrost. By the aid of the air conditioner, the air conditioner control method and the air conditioner control device, the problem of inaccuracy of a frosting control manner of the air conditioner in the prior art is solved, the problem of reduction of operational reliability and capability of a unit due to uncleanness in defrosting or frostless frosting can be further avoided, and frosting accuracy of the air conditioner is improved.

Description

technical field [0001] The present invention relates to the field of air conditioners, in particular to an air conditioner and its control method and device. Background technique [0002] The conventional defrosting control methods of air-cooled cold (hot) water units include timing defrosting method, time-temperature defrosting method, and inlet and outlet air pressure difference defrosting method, which adopt a single time, temperature, pressure difference condition or The combination of the two is the condition for the unit to enter defrosting. When the temperature and pressure difference sensors fail, precise defrosting will no longer be possible. The long-term operation of the unit in winter results in large energy consumption, and the heating effect cannot reach the optimal state of the designed unit. [0003] Aiming at the inaccurate defrosting control mode of the air conditioner in the prior art, no effective solution has been proposed yet. Contents of the inventi...
