Embodiment Construction

[0041] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0042] The air conditioner 10 mentioned in the present application performs a refrigeration cycle of the air conditioner 10 by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle consists of a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to air that has been conditioned and heat exchanged.

[0043] The compressor 100 compresses refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process...

Abstract

The invention discloses an air conditioner and a control method thereof.The air conditioner comprises a compressor, a four-way valve, an indoor heat exchanger, a throttling device, an outdoor heat exchanger, an outdoor fan, a flow control valve set and a controller; the flow control valve group comprises at least two flow control valves which are respectively connected between the outlet of the compressor and the corresponding heat exchange parts; the controller is configured to: operate a heating mode; and when the air conditioner meets the defrosting condition, a defrosting mode is operated, specifically, the outdoor fan is closed, and the at least two flow control valves are opened according to a preset mode until the at least two heat exchange parts complete defrosting. In this way, after the outdoor heat exchanger is frosted, the flow control valve is controlled to be opened, so that the refrigerant enters the heat exchange part to defrost the heat exchange part. And meanwhile, when part of the heat exchange parts in the air conditioner are defrosted, the other heat exchange parts are in a heating mode.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a control method thereof. Background technique [0002] In related technologies, when the air conditioner is in the heating mode for a long time, the outdoor heat exchanger is in the state of absorbing heat for a long time, and a large amount of frost will condense on the outdoor heat exchanger, which will affect the use of the outdoor heat exchanger . In related technologies, the frost on the outdoor heat exchanger can be eliminated by running the air conditioner in a defrosting mode. However, in the prior art, when the air conditioner operates in the defrosting mode, the air conditioner is often not allowed to perform heating. Therefore, when the air conditioner operates in the defrosting mode, the user experience of the indoor environment is poor. Contents of the invention [0003] The present invention aims to solve at least one of the tech...
