Problems solved by technology

[0003] like figure 1 As shown, in the prior art, an oil discharge port and a pipeline are usually provided at the bottom of the gas-liquid separator 100', so that the oil can be discharged from the gas-liquid separator 100' and returned to the compressor 200'. Due to the viscosity of the oil Larger, when the power of oil discharge is insufficient, the oil return efficiency is low, and the gas-liquid separator 100' will still be blocked

Embodiment 1

[0036] like figure 2 As shown, the air conditioning unit provided in this embodiment includes: a gas-liquid separator 100, the gas-liquid separator 100 is provided with an oil discharge port 102; an oil pumping assembly 400 is connected to the gas-liquid separator 100, and the oil pumping assembly 400 is provided with a The oil passage and the oil suction passage communicate with the oil discharge port 102, and the oil suction assembly 400 provides suction.

[0037] The air conditioning unit provided by the present invention is provided with an oil discharge port 102 on the gas-liquid separator 100, and also includes an oil pumping assembly 400 connected to the gas-liquid separator 100, the oil pumping channel of the oil pumping assembly 400 is connected to the oil discharge port 102, The oil pumping assembly 400 provides suction, so that the oil inside the gas-liquid separator 100 can flow out from the oil discharge port 102 smoothly. The air-conditioning unit provided by th...

Embodiment 2

[0039] like figure 2 As shown, in a specific embodiment of the first embodiment, the air conditioner unit further includes: a compressor 200, the compressor 200 has an intake end 201, and the oil suction channel communicates with the intake end 201.

[0040] In this embodiment, the oil suction channel transports the oil extracted from the gas-liquid separator 100 to the compressor 200, so as to supply the compressor 200 with the oil required for its normal operation, so that the oil enters the system for circulation and avoids waste of oil.

Embodiment 3

[0042] like figure 2 As shown, in the above embodiment, the oil extraction assembly 400 includes: an oil extraction pipe 401, the first end of which is connected to the oil discharge port 102; a Venturi tube 402, an oil extraction channel is arranged in the Venturi tube 402, and the oil extraction The channel is provided with an air inlet and an exhaust port, and the Venturi tube 402 is also provided with a connection part 4021. The connection part 4021 is provided with an oil suction port connected to the oil suction channel, and the second end of the oil suction pipe 401 is connected to the oil suction port.

[0043] In this embodiment, according to the principle of the Venturi effect, the pressure is low where the flow rate is fast, and the pressure in the gas-liquid separator 100 is greater than the pressure at the connection part 4021 of the oil suction channel, between the gas-liquid separator 100 and the oil suction channel A pressure difference is formed, the first end ...

Abstract

The invention provides an air conditioning unit. The air conditioning unit comprises a gas-liquid separator and an oil pumping assembly, the gas-liquid separator is provided with an oil discharge port, the oil pumping assembly is connected with the gas-liquid separator, the oil pumping assembly is provided with an oil pumping channel, the oil pumping channel communicates with the oil discharge port, and the oil pumping assembly provides suction force. According to the air conditioning unit, oil discharge power is increased through the oil pumping assembly so that oil in the gas-liquid separator can be pumped out from the oil discharge port, blockage of the gas-liquid separator is avoided, meanwhile, the part of oil flows back to a compressor, continuous reduction of the oil amount of the compressor is avoided, and normal work of the whole air conditioning unit is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to an air-conditioning unit. Background technique [0002] Air-cooled heat pump units are generally equipped with a gas-liquid separator. When the oil in the system flows through the gas-liquid separator with the refrigerant, the oil is retained in the gas-liquid separator due to the reduction of the flow rate. If this part of the oil is not discharged in time, the oil will accumulate more and more, causing the gas-liquid separator to fail. Blockage, so it is necessary to discharge this part of the oil through certain measures. [0003] like figure 1 As shown, in the prior art, an oil discharge port and a pipeline are usually provided at the bottom of the gas-liquid separator 100', so that the oil can be discharged from the gas-liquid separator 100' and returned to the compressor 200'. Due to the viscosity of the oil Larger, when the power of oil di...
