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, the user's heating demand for the indoor environment cannot be met during the defrosting process, which s

Embodiment 1

[0056] Combine below figure 1 and figure 2 , the air conditioner according to the embodiment of the present invention will be described in detail.

[0057] like figure 1 and figure 2 As shown, the air conditioner according to the embodiment of the present invention includes: an indoor heat exchanger 102, a gas-liquid separator 120, a compressor 104 and an outdoor heat exchanger 106 in annular communication; The first end of the defrost bypass 108 is connected to the supplemental air port G of the compressor 104, and the second end of the supplemental defrost bypass 108 is connected to the inlet of the gas-liquid separator 120, wherein when the air conditioner operates in the heating mode At this time, the defrosting refrigerant can flow into the supplemental air defrosting bypass 108 through the exhaust port F of the compressor 104, and continue to flow to the outdoor heat exchanger 106 for defrosting operation.

[0058] In this technical solution, the first end of the s...

Embodiment 2

[0084] image 3 A schematic flow chart of a defrosting method according to an embodiment of the present invention is shown.

[0085] like 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 operating in the heating mode, detecting the operating temperature of the outdoor heat exchanger of the air conditioner; step S304, determining the operating temperature The magnitude relationship between the ambient temperature and the preset temperature is determined, and whether to perform the defrosting process on the outdoor heat exchanger is determined according to the magnitude relationship.

[0086] In this technical solution, a bypass for air supplementation and defrosting is set to be connected in parallel with the indoor heat exchanger, and whether to defrost the outdoor heat exchanger is determined according to the size relationship. When defrosting operation is require...

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 gas-liquid separator, a compressor andan outdoor heat exchanger which communicate annularly, and further comprises a gas supplementation defrosting bypass, the first end of the gas supplementation defrosting bypass is connected to a gas supplementation opening of the compressor, and the second end of the gas supplementation defrosting bypass is connected to an inlet of the gas-liquid separator; and when the air conditioner is in the heating mode, a defrosting refrigerant can flow into the gas supplementation defrosting bypass through an exhaust opening of the compressor and continue flowing towards the outdoor heat exchanger for defrosting operation. Through the technical scheme, on the premise that mode switching of the air conditioner is reduced, defrosting operation is conducted in time, the operation reliability of the airconditioner is improved, the service life of the air conditioner is prolonged, and accordingly, the using experience of a user 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 the related art, when the air conditioner operates in the heating mode, the outdoor heat exchanger may run for a long time to generate frost, and the frost layer will affect the heat exchange efficiency. The compressor switches from the heating mode to the cooling mode, that is, the compressor sends the high-temperature and high-pressure refrigerant to the outdoor heat exchanger for defrosting operation. However, the above defrosting operation includes at least the following technical defects: [0003] (1) When switching from heating mode to cooling mode, a large amount of hardware is required for action switching. For example, the four-way valve needs to switch the flow direction, and the compressor needs to switch the operating frequency, and th...
