Embodiment 1

[0035] Such as Figure 1-4 As shown, an air conditioner outdoor unit includes a compressor, an outdoor heat exchanger and a chassis, and the chassis includes a chassis upper bottom 1 and a chassis lower bottom 2 arranged from top to bottom, and the chassis upper bottom There is an interlayer between 1 and the lower bottom of the chassis 2, and a refrigerant pipeline 3 is arranged in the interlayer, and the refrigerant pipeline 3 is connected in parallel with the outdoor heat exchanger. The inlet of the outdoor heat exchanger communicates with the exhaust pipeline of the outdoor unit of the air conditioner, and the outlet of the outdoor heat exchanger communicates with the air return port of the outdoor unit of the air conditioner.

[0036] The refrigerant pipeline 3 is arranged in the interlayer between the upper bottom 1 of the chassis and the lower bottom 2 of the chassis, that is, in the hollow chamber between the upper bottom 1 of the chassis and the lower bottom 2 of the ...

Embodiment 2

[0048] An air conditioner, comprising the above-mentioned air conditioner outdoor unit.

Embodiment 3

[0050] A control method of an air conditioner, the control method of the air conditioner uses the outdoor unit of the air conditioner described in Embodiment 1 to heat the air conditioner, and when defrosting, the refrigerant pipeline inlet 301 of the refrigerant pipeline 3 is connected to the The exhaust pipeline of the outdoor unit of the air conditioner is connected, the outlet 302 of the refrigerant pipeline 3 is connected with the air return port of the outdoor unit of the air conditioner, and the refrigerant pipeline 3 can discharge the gas from the exhaust pipeline. The high-temperature refrigerant is introduced into the refrigerant pipeline 3, and the ice on the chassis is eliminated by the heat dissipated by the high-temperature refrigerant.

[0051] During cooling and heating, the refrigerant pipeline inlet 301 of the refrigerant pipeline 3 communicates with the exhaust pipeline, and the refrigerant pipeline outlet 302 of the refrigerant pipeline 3 communicates with t...

Abstract

The invention provides an air conditioning outdoor unit, an air conditioner and an air conditioner control method. The air conditioning outdoor unit comprises a compressor, an outdoor heat exchanger and a chassis, wherein the chassis comprises a chassis upper bottom and a chassis lower bottom arranged from top to bottom; an interlayer is arranged between the chassis upper bottom and the chassis lower bottom; and a refrigerant pipeline is arranged in the interlayer and is connected with the outdoor heat exchanger in parallel. The air conditioning outdoor unit, the air conditioner and the air conditioner control method have the advantages of being thorough in deicing, high in long-term operating stability, simple in structure and easy to implement, and improving the refrigerating and heatingeffect of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner outdoor unit, an air conditioner and a control method for the air conditioner. Background technique [0002] At present, the heat pump type household room air conditioner uses an air-cooled finned heat exchanger. When the air flows through the heat exchanger, if the coil temperature of the outdoor heat exchanger is lower than the dew point temperature of the air, the air contained The moisture will precipitate and adhere to the surface of the coil to form a frost layer. The greater the temperature difference between the coil surface and the inlet air, the faster and more severe the frost build-up. As the frost layer forms, the heating capacity of the air conditioner decreases. When the defrosting condition of the air conditioner is reached, the air conditioner starts the defrosting mode to turn the frost layer formed on the condenser into water. Wat...
