Embodiment 1

[0035] image 3 It is a flow chart of the defrosting method of the air conditioner of the present invention. Wherein, the air conditioner operates in a heating mode.

[0036] like image 3 As shown, the air-conditioning defrosting method of the embodiment of the present invention includes the following steps:

[0037] S101: When the air conditioner is in a frosting state, detect the air conditioning capability of the air conditioner within a first preset time period.

[0038] It should be noted that, based on the aforementioned air conditioner system, during the heating operation of the air conditioner, the outdoor heat exchanger will frost due to condensation. After the frost state, judge whether to defrost or not.

[0039] It should also be noted that since the outdoor unit of the air conditioner needs to absorb heat when it condenses, if the outdoor unit of the air conditioner is frosted, the temperature near the outdoor unit of the air conditioner will be further reduc...

Embodiment 2

[0065] Figure 5 It is a schematic block diagram of the defrosting device of the air conditioner according to the embodiment of the present invention. like Figure 5 As shown, the air conditioner defrosting device 10 according to the embodiment of the present invention includes: a capacity detection module 11 , a judging module 12 and a control module 13 .

[0066] Among them, the capacity detection module 11 is used to detect the air-conditioning capacity of the air-conditioner within the first preset time period when the air-conditioner is in the frosting state; the judging module 12 is used to judge whether the current frosting speed of the air-conditioner is based on the detected air-conditioning capacity. exceeding the preset frosting speed; the control module 13 is used to control the air conditioner to enter the defrosting process when the current frosting speed exceeds the preset frosting speed.

[0067] Further, the judging module 12 is specifically used to: acquire...

Abstract

The invention discloses an air conditioner, and a defrosting method and device thereof. The air conditioner is operated in a heating mode. The method comprises the steps of detecting the air conditioner capacity in a first preset time period when the air conditioner is in the frosting state; judging whether the current frosting velocity of the air conditioner exceeds the preset frosting velocity or not according to the detected air conditioner capacity; controlling the air conditioner to enter a defrosting process when the current frosting velocity exceeds the preset frosting velocity, and achieving judgment on the frosting condition according to the air conditioner capacity, so that the air conditioner can enter the defrosting process in time, and the defrosting effect is improved effectively under the condition that the heating effect of the air conditioner is ensured.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and its defrosting method and device. Background technique [0002] During the heating operation of the air conditioner, the outdoor heat exchanger operates as a condenser. At this time, due to the low outdoor temperature, the heat absorption and condensation of the outdoor heat exchanger may easily cause frosting on the outdoor heat exchanger. Perform defrosting operation. [0003] In the related art, in order to control the defrosting process of the air conditioner, it is usually determined whether the air conditioner is defrosting by judging whether the temperature of the outdoor heat exchanger reaches a preset temperature. However, the problem with the related technology is that it is difficult to unify the judgment conditions of the defrosting operation due to the different environmental factors of the air conditioner. Problems that affect user ...
