[0021] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0022] The present invention provides an air-inflation liquid separator, comprising a liquid separation component and an air-inflation component. The liquid separation component and the air-inflation component are an integrated structure, and the gaseous refrigerant separated by the liquid separation component and the gaseous refrigerant introduced into the air-inflation liquid separator can be mixed in the air-inflation liquid separator and then transported to a compressor.

[0023] The air-inflation liquid separator integrates the air-inhalation liquid separator with the air-inflation liquid separator, which not only realizes the gas-liquid separation function of the conventional liquid separator, but also realizes the air-inflation enthalpy-increasing function. The air-inflation liquid separator integrates the air-inhalation liquid separator with the air-inflation liquid separator, which not only realizes the gas-liquid separation function of the conventional liquid separator, but also eliminates the independent assembly of the air-inflation liquid separator, reduces the parts processing procedures, and improves the production efficiency. When installing the whole machine, there is no need to install the enthalpy-increasing pump suction pipe and the enthalpy-increasing liquid separator at the same time, which improves the assembly efficiency of the whole machine.

[0024] As an optional implementation, the gas-liquid replenishing separator includes a shell, which is connected to an intake pipe 1 for introducing low-temperature and low-pressure gas from the outlet of the evaporator, an enthalpy-increasing gas-replenishing pipe 6 for introducing low-temperature and medium-pressure gas from the outlet of the flash evaporator, and an exhaust pipe 5 for connecting to the compressor; the shell includes an isolated liquid separation chamber and an enthalpy-increasing gas-replenishing chamber, the intake pipe 1 is connected to the liquid separation chamber to form a liquid separation component, and the enthalpy-increasing gas-replenishing pipe 6 is connected to the enthalpy-increasing gas-replenishing chamber to form an gas-replenishing component.

[0025] The suction pipe 1 is used to introduce the low-temperature and low-pressure gas from the evaporator outlet, and the enthalpy-increasing air supply pipe 6 introduces the low-temperature and medium-pressure gas from the flash evaporator outlet. The exhaust pipe 6 discharges the mixed gas to the compressor, combining the traditional gas-liquid separator and the gas-liquid supply separator into one, reducing the processing and assembly procedures of parts and greatly improving production efficiency and assembly efficiency.

[0026] As an optional implementation, a mixing buffer tube 3 is further provided in the shell, the liquid separation chamber and the enthalpy increase gas supplement chamber are respectively connected to the mixing buffer tube 3, and the outlet of the mixing buffer tube 3 can be connected to the compressor through the exhaust pipe 5.

[0027] The low-temperature and low-pressure gas introduced by the suction pipe 1 is mixed with the gaseous refrigerant after gas-liquid separation and the low-temperature and medium-pressure gas introduced by the enthalpy-increasing air supply pipe 6 in the mixing buffer pipe 3 and then transported to the compressor. The structure is simple and reliable; and the mixing buffer pipe 3 is located inside the shell, which reduces heat loss and has a compact and reasonable structure.

[0028] As an optional implementation, the mixing buffer tube 3 includes a mixing passage and a first branch and a second branch connected in parallel. The inlet of the first branch is located in the liquid separation chamber, and the inlet of the second branch is located in the enthalpy increase and gas supplement chamber. The first branch and the second branch are connected to the mixing passage after they intersect.

[0029] The mixing buffer tube 3 introduces the gas from the liquid separation chamber and the enthalpy increasing gas supplement chamber respectively through the first branch and the second branch. The first branch and the second branch are merged to form a mixing passage, and the pipeline is simple.

[0030] The inlet on the first branch is set at the starting section of the first branch, and the starting section of the first branch can be provided with upper and lower inlets; the inlet on the second branch is set at the starting section of the second branch, and the starting section of the second branch can be provided with upper and lower inlets to facilitate the circulation of gas.

[0031] As an optional implementation, the first branch includes an inclined pipe section, and the second branch is a straight pipe.

[0032] The first branch includes an inclined pipe section, which reduces the gas mixing resistance.

[0033] As an optional implementation, the inner diameter of the first branch is smaller than the inner diameter of the second branch.

[0034] The first branch contains gas with lower pressure. The inner diameter of the first branch is smaller than that of the second branch. The first branch will produce a certain low-pressure area, which will prompt the low-temperature and low-pressure refrigerant to flow here, reduce the flow resistance of the refrigerant, and at the same time, reduce the mixing loss of the low-temperature and low-pressure gas and the low-temperature and medium-pressure gas, thereby improving the performance of the compressor.

[0035] As an optional implementation, the air intake pipe 1 and the enthalpy-increasing air supply pipe 6 are located at a first end of the shell, and the exhaust pipe 5 is located at a second end of the shell opposite to the first end.

[0036] The gas inlet is located at the first end of the shell, and the gas outlet is located at the second end of the shell opposite to the first end, which is conducive to gas mixing and flow with small loss.

[0037] As an optional implementation, the exhaust pipe 5 is a bent pipe.

[0038] The exhaust pipe 5 is a curved pipe, which increases the refrigerant flow path and further improves the gas-liquid separation effect.

[0039] like Figure 1As shown, the present invention improves on the structure of a conventional liquid distributor. The shell of the gas-supplementing liquid distributor includes a body 2 and a lower cover 4. Two air intakes are arranged on the body 2, which are connected to the air intake pipe 1 and the enthalpy-increasing air intake pipe 6 respectively. The air intake pipe 1 is fed with low-temperature, low-pressure gas from the outlet of the evaporator, with a pressure of Pe, and the air intake pipe 6 is fed with low-temperature, medium-pressure gas from the outlet of the flash evaporator, with a pressure of Pm. The refrigerant through the enthalpy-increasing air intake pipe 6 is relatively independent of the air intake pipe 1. The low-temperature, low-pressure gas enters the liquid-supplementing chamber from the air intake pipe 1, and then flows to the right to the lower cover 4, and then flows to the left to the entrance of the steel pipe serving as the mixing buffer tube 3, and enters the inclined tube serving as the first branch, while the low-temperature, medium-pressure gas enters the air intake chamber from the enthalpy-increasing air intake pipe 6, and then enters the straight tube serving as the second branch of the mixing buffer tube 3. The low-temperature low-pressure gas and the low-temperature medium-pressure gas are mixed at the intersection of the straight pipe and the inclined pipe of the enthalpy increase gas supply pipe 6, and then enter the compressor through the exhaust pipe 5.

[0040] Among them, Pm needs to be greater than Pe, and the inner diameter of the inclined tube of the enthalpy increase air supply pipe 6 is smaller than the inner diameter of the straight tube. According to the ejector principle, at the intersection of the inclined tube and the straight tube, the inclined tube will produce a certain low-pressure area, prompting the low-temperature and low-pressure refrigerant to flow here, reducing the flow resistance of the refrigerant, and at the same time, reducing the mixing loss of the low-temperature and low-pressure gas and the low-temperature and medium-pressure gas, thereby improving the performance of the compressor.

[0041] Since the liquid separator of the present invention integrates the gas-liquid separation effect of the conventional liquid separator and the gas-increasing enthalpy-increasing effect of the gas-increasing liquid separator, the compressor does not need to add an enthalpy-increasing component, thereby improving the production efficiency of the compressor.

[0042] The present invention provides a compressor, comprising any one of the above-mentioned air-infusing liquid separators.

[0043] The air-supply liquid distributor integrates the air-intake liquid distributor with the air-supply liquid distributor, which not only realizes the gas-liquid separation function of the conventional liquid distributor, but also realizes the air-supply enthalpy increase function, while reducing the flow resistance of the air-supply gas, reducing the power consumption of the compressor, and improving the production efficiency of the enthalpy increase compressor; since the independent assembly of the air-supply liquid distributor is cancelled, the flow resistance of the refrigerant and the air-supply gas resistance are reduced, and the production efficiency of the compressor is improved.

[0044] The present invention provides an air conditioner, comprising the above-mentioned compressor.

[0045] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
