Problems solved by technology

[0003] (1) When switching from the heating mode to the cooling mode, a large amount of hardware is required to switch the action, for example, the four-way valve needs to switch the flow direction, and the compressor needs to switch the operating frequency, and the above action switching may lead to hardware failure and shortened life
[0004] (2) Since the heating mode is switched to the cooling mode, during the defrosting process, the user's heating demand for the indoor environment cannot be met, which seriously affects the user experience
[0005] (3) When the outdoor ambient temperature is low, for example, below minus 20°C, the humidity in the outdoor ambient temperature is very low. At this time, the outdoor unit of the air conditioner is not easy to frost, but the air conditioner depends on the outdoor ambient temperature and the outlet of the outdoor heat exchanger. The temperature determines whether to execute the defrosting action, which will lead to no frost defrosting or insufficient defrosting

Embodiment 1

[0055] Combine below figure 1 and figure 2 , the air conditioner according to the embodiment of the present invention will be specifically described.

[0056] Such as figure 1 and figure 2 As shown, the air conditioner according to the embodiment of the present invention includes: an annularly connected indoor heat exchanger 102, a compressor 104, and an outdoor heat exchanger 106; a defrosting branch 108 is connected in parallel with the indoor heat exchanger 102, wherein , when the air conditioner is running in the heating mode, the defrosting refrigerant can flow into the defrosting branch 108 through the exhaust port of the compressor 104, and continue to flow into the outdoor heat exchanger 106 for defrosting operation.

[0057] In this technical solution, by setting the defrosting branch 108 in parallel connection with the indoor heat exchanger 102, when defrosting operation is required, there is no need to switch from the heating mode to the cooling mode, and the u...

Embodiment 2

[0082] image 3 A schematic flowchart of a defrosting method according to an embodiment of the present invention is shown.

[0083] Such as image 3 As shown, the defrosting method according to an embodiment of the present invention includes: step S302, when it is detected that the air conditioner is running in the heating mode, detecting the operating temperature of the outdoor heat exchanger of the air conditioner; step S304, determining the operating temperature The size relationship between the ambient temperature and the preset temperature, and determine whether to defrost the outdoor heat exchanger according to the size relationship.

[0084] In this technical solution, by setting the defrosting branch in parallel connection with the indoor heat exchanger, and determining whether to defrost the outdoor heat exchanger according to the size relationship, when defrosting operation is required, there is no need to switch the heating mode to In the cooling mode, the user's ...

Abstract

The invention provides an air conditioner, a defrosting method and a computer readable storage medium. The air conditioner comprises an indoor heat exchanger, a compressor, an outdoor heat exchanger and a defrosting branch, wherein the indoor heat exchanger, the compressor and the outdoor heat exchanger annularly communicate with one other; the defrosting branch is connected with the indoor heat exchanger in parallel; and when the air conditioner is operated in a heating mode, a defrosting coolant can flow into the defrosting branch through an exhaust port of the compressor and continues to flow into the outdoor heat exchanger for defrosting operation. Through the technical scheme, on the premise that air conditioner mode switching is reduced, the defrosting operation is conducted in time,the operation reliability of the air conditioner is improved, the service life of the air conditioner is prolonged, and thus the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to an air conditioner, a defrosting method and a computer-readable storage medium. Background technique [0002] In related technologies, when the air conditioner is running in the heating mode, the outdoor heat exchanger may generate frost after running for a long time, and the frost layer will affect the heat exchange efficiency. Therefore, the control module of the air conditioner usually combines the outdoor operating temperature and The outlet temperature at the bottom of the outdoor heat exchanger determines whether defrosting operation is required. When defrosting operation is required, the air conditioner switches from heating mode to cooling mode, that is, the compressor sends high-temperature and high-pressure refrigerant to the outdoor heat exchanger to Perform a defrosting operation, however, the above-mentioned defrosting operation includes at least...
