As shown in fig. 1, a gas-liquid separator according to a preferred embodiment of the present invention includes a cylinder 100 and a liquid level control device 200.
An inlet pipe 110 and an outlet pipe 120 are respectively arranged at two ends of the cylinder body 100, a separation cavity 130 is arranged in the cylinder body 100, the inlet pipe 110 and the outlet pipe 120 are both communicated with the separation cavity 130, a pipe orifice of one end of the outlet pipe 120 extending into the separation cavity 130 is arranged upwards, a preset distance A is arranged between the pipe orifice and the bottom wall of the separation cavity 130, and the other end of the outlet pipe 120 is communicated with the compressor body 400.
The liquid level control device 200 is disposed in the separation chamber 130 and includes a first baffle 210 and a floating ball 220.
The first baffle 210 is arranged in the separation cavity 130, the top of the first baffle 210 is provided with a vent hole 211 for gaseous refrigerant to pass through, and the distance between the bottom of the vent hole 211 and the bottom wall of the separation cavity 130 is less than a preset distance A; the bottom of the first baffle 210 is provided with an oil through hole 212 through which the liquid refrigerant and the refrigerating machine oil pass.
The oil hole 212 is an oil return hole when no liquid refrigerant exists, and can return the refrigerating machine oil to the compressor body 400 under a normal working state, specifically, when the refrigerant enters the gas-liquid separator from the inlet pipe 110, the refrigerant can carry the refrigerating machine oil, the refrigerating machine oil is in a droplet state and is mixed in the refrigerant, when the refrigerant passes through the filter disc 300, the refrigerating machine oil can be separated and mixed with the liquid refrigerant, and the gaseous refrigerant can contact with the liquid level of the liquid refrigerant and the refrigerating machine oil in the process of passing through the first channel 240 and the vent hole 211 and then entering the discharge pipe 120, so that the refrigerant can carry the small droplets of the refrigerating machine oil again to be mixed into the gaseous refrigerant and enter the compressor from the discharge pipe 120, and the engine oil is provided for the movement of the compressor. However, it should be noted that the amount of the refrigerating machine oil is small, and the liquid level thereof does not accumulate at the opening of the discharge pipe 120 in the gas-liquid separator. After the liquid refrigerant enters the gas-liquid separator, the oil through hole 212 is a vaporization orifice.
The first baffle 210 divides the separation chamber 130 into two chambers, and for convenience of description, the chamber on one side of the first baffle 210 facing the inlet pipe 110 is referred to as a first chamber 131, and the chamber on the other side of the first baffle 210 is referred to as a second chamber 132.
The floating ball 220 is located in the separation chamber 130 between the first baffle 210 and the inlet pipe 110, that is, the floating ball 220 is disposed in the first chamber 131. The floating ball 220 is made of a material which does not chemically react with the mixture of the refrigerant and the refrigerating machine oil, and the floating ball 220 is not corroded by the mixture of the refrigerant and the refrigerating machine oil. The floating ball 220 may be made as a hollow ball, and the average density of the floating ball 220 is less than that of the refrigerant and the refrigerator oil, so as to ensure that the floating ball 220 can float on the liquid surface in the mixture of the refrigerant and the refrigerator oil.
The outer diameter of the float ball 220 is larger than the inner diameter of the vent hole 211, so that the float ball 220 does not pass through the vent hole 211.
When the liquid level in the separation chamber 130 rises, the floating ball 220 can float on the liquid level and rise along with the liquid level; when the liquid level rises to the vent hole 211, the float ball 220 closes the vent hole 211.
Specifically, the refrigerant enters the first cavity 131 from the inlet pipe 110, wherein the gaseous refrigerant directly enters the second cavity 132 from the vent hole 211, and then enters the discharge pipe 120 from the second cavity 132, so as to provide the gaseous refrigerant for the compressor body 400. The liquid refrigerant is accumulated in the first cavity 131, and when the liquid level of the liquid refrigerant rises to the oil through hole 212, the liquid refrigerant enters the second cavity 132 through the oil through hole 212, and since the predetermined distance a is set between the pipe orifice and the bottom wall of the separation cavity 130, that is, the height of the pipe orifice is limited, and the height of the oil through hole 212 is lower than that of the pipe orifice, the liquid level of the liquid refrigerant is further away from the position of the pipe orifice, and the liquid refrigerant does not enter the discharge pipe 120 from the pipe orifice, thereby preventing the liquid slugging of the compressor body 400.
As the liquid refrigerant is accumulated, the liquid levels of the liquid refrigerant in the first and second chambers 131 and 132 are the same, and the float ball 220 rises along with the rise of the liquid level until the liquid level rises to the vent hole 211. When the liquid level of the first chamber 131 just rises above the vent hole 211, because it takes time for the oil hole 212 to balance the liquid levels of the first chamber 131 and the second chamber 132, the liquid refrigerant at this moment enters the second chamber 132 from the vent hole 211, and the surface tension of the liquid level drives the floating ball 220 to move toward the vent hole 211 until the floating ball 220 is "sucked" at the vent hole 211 to close the vent hole 211. This process is instantaneously formed, so that the liquid refrigerant introduced into the second chamber 132 from the vent hole 211 is very small, and the liquid refrigerant does not enter the compressor body 400, thereby preventing the occurrence of liquid slugging.
After the floating ball 220 closes the vent hole 211, the compressor body 400 still works, and the gaseous refrigerant in the second chamber 132 is further transported into the compressor body 400 through the discharge pipe 120. This will gradually decrease the air pressure in the second chamber 132, and a pressure difference is formed between the second chamber 132 and the first chamber 131. The liquid refrigerant in the first chamber 131 flows from the first chamber 131 to the second chamber 132 through the oil hole 212 under the action of the pressure difference. When the pressure of the second cavity 132 is lower than the saturation pressure of the refrigerant, the refrigerant in the second cavity 132 changes from liquid to gas, and the gas refrigerant is delivered to the compressor body 400 through the discharge pipe 120 and enters the compressor body 400 along with the change from the liquid refrigerant to the gas refrigerant. In this process, only the gaseous refrigerant enters the discharge pipe 120, and the liquid refrigerant does not enter the compressor body 400, thereby preventing liquid slugging. Thereafter, the liquid refrigerant in the first cavity 131 decreases, the liquid level of the liquid refrigerant decreases, the floating ball 220 also decreases, and the gaseous refrigerant in the first cavity 131 can enter the second cavity 132 through the vent hole 211 and then enter the discharge pipe 120.
Then, the liquid refrigerant is accumulated, and the liquid level rises to form a cycle.
In summary, the gas-liquid separator of the present embodiment does not allow the liquid refrigerant to enter the compressor body 400 during the use process due to the structure, so that the liquid impact of the compressor can be completely prevented. But also broken through among the prior art "vapour and liquid separator holds the volume of liquid refrigerant and received the restriction of self volume size", the vapour and liquid separator of this embodiment no longer through store all liquid refrigerants inside and prevent the liquid attack, but converts partial liquid refrigerant into gaseous refrigerant, makes vapour and liquid separator no longer receive the restriction of self size just can prevent the liquid attack, reduces vapour and liquid separator self size, reduces the occupation to the space.
On the basis, the gas-liquid separator can be further improved.
The fluid level control apparatus 200 further includes a second baffle 230, the second baffle 230 being disposed in the separation chamber 130 between the first baffle 210 and the inlet pipe 110, and the float ball 220 being positioned between the first baffle 210 and the second baffle 230. For convenience of illustration, the separation chamber 130 between the first barrier 210 and the second barrier 230 is denoted as a limit chamber 133.
The second baffle 230 has an upper notch 231 at the top thereof, a first channel 240 is formed between the upper notch 231 and the top wall of the separation chamber 130, the first channel 240 is used for gaseous refrigerant to pass through, and the distance B between the upper notch 231 and the top of the top wall of the separation chamber 130 is smaller than the outer diameter of the floating ball 220. This distance B should be understood as follows: the distance between the lowest point of the upper cutout 231 and the highest point of the top wall of the separation chamber 130, that is, the maximum distance between the upper cutout 231 and the inner wall of the top of the separation chamber 130. So configured, the float ball 220 will not leave the stopper cavity 133 from the first passage 240.
In this embodiment, the cross-sectional area of the first channel 240 is larger than the cross-sectional area of the inlet pipe 110, and the cross-sectional area refers to a vertical cross-section of the flow direction of the refrigerant. Thereby reducing the suction pressure loss of the gaseous refrigerant entering from the inlet pipe.
The bottom of the second baffle 230 is provided with a lower notch 232, a second channel 250 is formed between the lower notch 232 and the bottom wall of the separation cavity 130, the second channel 250 is used for liquid refrigerant and refrigerating machine oil to pass through, and the distance C between the lower notch 232 and the bottom of the bottom wall of the separation cavity 130 is smaller than the outer diameter of the floating ball 220. The distance C should be understood as follows: the distance between the highest point of the lower cutout 232 and the lowest point of the top of the separation chamber 130, i.e., the maximum distance between the lower cutout 232 and the bottom of the separation chamber 130. So configured, the float ball 220 will not leave the stopper cavity 133 from the second passage 250.
Through the structure, the position of the floating ball 220 can be limited, the flowing of liquid refrigerant and gaseous refrigerant can not be influenced, when the liquid level of the first cavity 131 just rises to be higher than the vent hole 211, the floating ball 220 can be more quickly sucked at the vent hole 211 through the limiting cavity 133, and the liquid refrigerant entering the second cavity 132 from the vent hole 211 is further reduced.
In the present embodiment, the inner diameter of the vent hole 211 is larger than that of the inlet pipe 110, so as to reduce the suction pressure loss of the gaseous refrigerant entering from the inlet pipe.
The distance D between the center of the vent hole 211 and the top wall of the separation chamber 130 directly above it is equal to the radius of the float ball 220. The vent hole 211 is disposed on the center line of the first baffle 210, and the top wall of the separation chamber 130 directly above the vent hole 211 is the highest point of the inner wall of the separation chamber 130. Through the structure, when the floating ball 220 floats to the height of the vent hole 211, the floating ball 220 can be tangent to the inner wall of the top of the separation cavity 130, and the floating ball 220 can be ensured to seal the vent hole 211. If the distance D is greater than or less than the radius of the floating ball 220, the floating ball 220 may not be able to close the vent hole 211.
The diameter of the oil passage hole 212 is related to the condition of vaporization of the liquid refrigerant.
Firstly, the discharge side pressure P1 is less than or equal to the gaseous saturation pressure Pb corresponding to the refrigerant, and the volume Qv of the gasified liquid refrigerant is less than or equal to the compressor gas transmission amount Qc, so that the pressure of the second cavity 132 is continuously reduced.
And (3) Qm: the mass flow rate of the refrigerant flowing out of the oil through hole 212;
μ: an efflux coefficient;
a: oil through hole 212 area;
ρ l: density of liquid refrigerant;
Qv＝Qm/ρg
ρ g: density of gaseous refrigerant;
Qc＝Vst·f
vst: compressor displacement;
f: the rotational speed of the compressor;
A＝(π·d^2)/4
ΔP＝P0-P1
p0: suction side pressure;
let Qv = Qc, from the above equation, the relationship of P1 to the aperture d:
P1＝P0-ΔP＝P0-1/(2·ρl)·((Vst·f·ρg)/(μ·π/4·d^2))^2≤Pb
when P1 takes a maximum value, P1= Pb, at which point the aperture d has a maximum value dmax;
namely: when d is greater than dmax, the volume Qv is greater than Qc after the liquid refrigerant passing through the oil through hole 212 is gasified, and the liquid refrigerant on the discharge side cannot be completely sucked by the compressor after being gasified, so that the liquid refrigerant on the discharge side cannot be completely gasified, the amount of the liquid refrigerant is increased, and the risk of entering the core of the compressor exists; in order to ensure sufficient oil return, a minimum aperture dmi n is ensured.
In this embodiment, the diameter of the oil hole 212 is 2mm-4mm, so that the liquid refrigerant in the second chamber 132 can be completely vaporized while the oil return amount is ensured.
The distance between the oil passage hole 212 and the bottom wall of the separation chamber 130 is smaller than the distance C between the lower cutout 232 and the bottom wall of the separation chamber 130. In a specific implementation, the oil through hole 212 is disposed as close to the bottom end of the first baffle 210 as possible.
The distance C between the lower cutout 232 and the bottom wall of the separation chamber 130 is 3mm to 5mm. The distance does not affect the liquid entering the limiting cavity 133, and the normal flow of the liquid refrigerant and the refrigerating machine oil is not affected by the arrangement of the second baffle 230.
The gas-liquid separator of the embodiment further comprises a filter disc 300, and the filter disc 300 is arranged in the separation cavity 130 between the inlet pipe 110 and the liquid level control device 200.
When the refrigerant enters the separation cavity 130 from the inlet pipe 110, the refrigerant passes through the filter disc 300, the filter disc 300 can filter impurities in the refrigerant, and can also separate the refrigerator oil, and both the refrigerator oil and the liquid refrigerant can enter the first cavity 131.
The embodiment also provides a compressor, which comprises the gas-liquid separator. The compressor includes a compressor body 400 and the above-described gas-liquid separator provided at an inlet pipe of the compressor. The compressor is usually connected with a condenser, a throttle valve and an evaporator through pipelines to form a refrigerant circulation loop, so as to form an air conditioning system. The compressor body 400 is used to suck a low-temperature and low-pressure gaseous refrigerant from the evaporator, compress the refrigerant into a high-temperature and high-pressure gaseous refrigerant, and send the compressed refrigerant into the condenser.
To sum up, the embodiment of the utility model provides a vapour and liquid separator and compressor, its vapour and liquid separator can prevent completely that the compressor from taking place the liquid and hit, and vapour and liquid separator also no longer receives self volume restriction moreover, and the reducible self size of vapour and liquid separator reduces the occupation to the space.
