The invention provides a defrosting control method, a defrosting control device, an air conditioner and a readable storage medium. The defrosting control method comprises the steps that after detection enters into a defrosting mode, a cold outlet temperature in an outdoor heat exchanger flow path and an exhaust temperature of a compressor are detected correspondingly according to a preset detection cycle; the corresponding defrosting trend temperature difference is determined according to the exhaust temperature and the cold outlet temperature which are detected in per detection cycle; and thetrend relation between the first defrosting trend temperature difference and the second defrosting trend temperature difference in per detection cycle is detected so that subsequent defrosting operation is carried out according to the trend relation, wherein each first defrosting trend temperature difference is the defrosting trend temperature difference determined after the current detection cycle is completed, and each second defrosting temperature is the defrosting trend temperature difference after the last detection cycle is completed. Through the technical scheme, the defrosting operation controllability is realized, the probability that an air conditioner outdoor unit still carries out defrosting operation after the defrosting is already finished is lowered, and thus energy attenuation arising from frost-free defrosting operation is reduced.
Description
technical field [0001] The present invention relates to the field of heat pumps, in particular to a defrosting control method, a defrosting control device, an air conditioner and a computer-readable storage medium. Background technique [0002] In the related technology, the outdoor unit of the air conditioner often defrosts cleanly but the outdoor unit of the air conditioner is still in the defrosting mode, leading to a no-frost defrost, and according to the control process, the no-frost defrost will continue for a period of time, and there are the following defects : [0003] (1) It affects the heating energy efficiency of the entire air conditioning system; [0004] (2) Even if the defrosting time without frost is too long, it will affect the normal use of the user. Contents of the invention [0005] In order to solve at least one of the above technical problems, an object of the present invention is to provide a defrosting control method. [0006] Another object of ...
