Embodiment 1

[0045] The air conditioner includes an outdoor unit heat exchanger and an auxiliary heating unit for heating the heat exchanger. The auxiliary heating unit is arranged on the back of the outdoor unit of the air conditioner, and is fixed on the outdoor unit through a support frame. Wherein, the auxiliary heating unit may be an electric heating wire.

[0046] When the air conditioner is running in the non-heating mode, the temperature of the heat exchanger at the outdoor unit is relatively high, and no frosting will occur. Therefore, no auxiliary heating of the heat exchanger is required when operating in non-heating mode. However, when the air conditioner operates in the heating mode, the heat exchanger exchanges heat to the room, and the fins of the outdoor heat exchanger have a relatively low temperature, which is prone to frosting.

[0047] The invention discloses an air conditioner auxiliary defrosting method, such as figure 1 with figure 2 shown, including the followi...

Embodiment 2

[0104] An auxiliary defrosting control device for an air conditioner, comprising: a detection unit, which is used to detect the real-time indoor temperature and the real-time temperature of an outer coil; Operation mode; the calculation unit also uses the real-time temperature of the outer coil to compare the temperature when the air conditioner enters the reverse cycle defrosting mode, and calculates the real-time change rate of the outer coil temperature according to the real-time temperature of the outer coil; the control unit implements the above-mentioned air conditioner Auxiliary defrosting method.

Embodiment 3

[0106] A computer-readable storage medium. The computer-readable storage medium stores a computer program. When the computer program is read and executed by a processor, the method in Embodiment 1 is implemented.

Abstract

The invention discloses an air conditioner auxiliary defrosting method and control device, a storage medium and an air conditioner, and relates to the field of air conditioners. The air conditioner auxiliary defrosting method comprises the following steps that S100, in a heating mode, the indoor real-time temperature T<room temperature> is detected, the operation stage of the air conditioner is judged based on the indoor real-time temperature T<room temperature> and the indoor target temperature T < target >; S200, based on an operation stage, the real-time temperature T<outer disc> of an outer coil pipe is detected, controlling an auxiliary heating unit is carried out according to the real-time temperature T<outer disc> of the outer coil pipe and the preset temperature T<2> of the outer coil pipe; and the air conditioner enters a reverse circulation defrosting mode based on the preset temperature T<2> of the outer coil pipe. According to the conditioner auxiliary defrosting method andcontrol device, the storage medium and the air conditioner, on the basis of not affecting a refrigerating and heating system of the air conditioner, heating an outdoor heat exchanger in an auxiliarymode is carried out, the problem that frost layers or ice layers at the bottom of the outdoor heat exchanger are seriously accumulated is solved, and the unit performance is improved to a certain extent.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner auxiliary defrosting method, a control device, a storage medium and an air conditioner. Background technique [0002] When the air conditioner is in heating operation, a layer of hoarfrost often appears on the windward side of the outdoor heat exchanger. Currently, the air conditioner enters the reverse cycle defrosting mode for defrosting. When the temperature of the outer coil of the heat exchanger is low, When the reverse cycle defrost temperature set by the air conditioner is reached, the air conditioner will perform reverse cycle defrost mode. During the process of entering the reverse cycle defrosting mode, the air conditioner is defrosted within a limited time. In the prior art, there is a method of shortening the time for the air conditioner to enter reverse cycle defrosting by using heating. [0003] However, in actual use, when the temperature of the...
