The air conditioning system is very easy to cause the phenomenon that the compressor sucks air and carries liquid due to insufficient evaporation and heat exchange under the low-temperature working condition, and even liquid impact can occur in serious conditions, so that the compressor is damaged. In order to deal with the problem, a liquid storage tank is additionally arranged at the air suction end of the compressor to separate gas-liquid refrigerant, so that the gas refrigerant enters the compressor cylinder from the liquid storage tank through a connecting pipe, the liquid refrigerant and lubricating oil are accumulated at the bottom of the liquid storage tank, a liquid return hole is formed in the side wall of the connecting pipe at the bottom of the liquid storage tank, and a mixture of the liquid refrigerant and the lubricating oil can enter the connecting pipe through the liquid return hole and then enter the compressor cylinder through the connecting pipe. The mixture of proper liquid refrigerant and lubricating oil enters the cylinder of the compressor, so that the phenomenon of air suction and liquid entrainment can be inhibited, the smooth oil return of the compressor is ensured, and the abrasion of the compressor is slowed down.
The existing liquid storage tank can inhibit the phenomenon of air suction and liquid entrainment to a certain extent, but the aperture of a liquid return hole of the existing liquid storage tank is fixed and can not be adjusted according to the change of the operation condition, so the application effect on a heat pump system operated at a wide temperature range is not ideal, the phenomenon of air suction and liquid entrainment still occurs, and the phenomenon of air suction and liquid entrainment is particularly obvious during the defrosting of a heat pump. Specifically, under high-temperature working conditions such as refrigeration and the like, evaporation heat exchange of the system is sufficient, the system has good air suction superheat degree, less liquid refrigerant is in the liquid storage tank, the liquid level is low, lubricating oil in the liquid at the bottom contains a large amount of components, the viscosity is high, the resistance is high when the lubricating oil passes through the liquid return hole, and meanwhile, because the liquid level is low, the flowing power of the liquid refrigerant and the lubricating oil mixture is low, the aperture of the liquid return hole is preferably large at the moment in order to ensure smooth oil return; under low temperature operating mode (including during the defrosting) such as super low temperature heating, the evaporation heat transfer of system is not enough, and the liquid refrigerant that gets into the liquid storage pot is many, and the liquid level is higher, and lubricating oil's composition is few in the liquid of bottom, and viscidity is little, and the resistance when passing back the liquid hole is little, and simultaneously because the liquid level is higher, liquid refrigerant and lubricating oil mixture flow power is great, in order to avoid breathing in the production of taking liquid phenomenon, the liquid hole aperture of returning this moment should set up something less. The aperture requirement of the liquid return hole under low-temperature working conditions such as ultralow-temperature heating is just opposite to that under high-temperature working conditions such as refrigeration, so that the existing liquid storage tank cannot meet the requirement of a wide-ring-temperature operation heat pump system.

Detailed Description
For simplifying the description process, the terms of upper and lower directions used in the present embodiment refer to the direction of the liquid storage tank in the use state.
Referring to fig. 1 to 7 in combination, according to an embodiment of the present invention, a liquid storage tank is provided, which includes a housing 1 and a connection pipe 2, wherein the connection pipe 2 is connected to the housing 1, and one end of the connection pipe 2 extends into a cavity formed by the housing 1, and the liquid storage tank further includes an overflow structure, where the overflow structure divides an area of the connection pipe insertion end of the housing 1 into a first liquid storage area 5 and a second liquid storage area 6, so that a liquid refrigerant and lubricating oil mixture in the first liquid storage area 5 can be shunted from the first liquid storage area 5 to the second liquid storage area 6 through the overflow structure after a liquid level rises to a preset height.
Of course, the overflow structure may be in various manners, and the amounts of the liquid refrigerant and the lubricant mixture that need to enter the air compressor are different in the oil storage tanks with different capacities, so that the preset height is matched with the actual working condition.
In the technical scheme, the overflow structure is additionally arranged, so that a single liquid storage cavity in the existing liquid storage tank is divided into a first liquid storage area 5 and a second liquid storage area 6, at the moment, when the air conditioner is under the low-temperature working conditions of ultralow-temperature heating and the like (including the defrosting period), relatively more liquid refrigerant and lubricating oil mixture enters the liquid storage tank, the liquid level formed by accumulation in the first liquid storage area 5 is higher, the viscosity of the liquid refrigerant and lubricating oil mixture is smaller, when the liquid level of the liquid refrigerant and lubricating oil mixture is higher than the liquid level of the overflow structure and is far away from the upper end of the first liquid storage area 5, the liquid refrigerant and lubricating oil mixture flows into the second liquid storage area 6, so that the liquid level in the first liquid storage area 5 is kept constant for a certain time, and the phenomenon that the liquidity of the liquid refrigerant and lubricating oil mixture is overlarge due to overlarge pressure difference caused by the overlarge liquid level in the first liquid storage area 5 is avoided, the mixture of the liquid refrigerant and the lubricating oil enters the connecting pipe 2 in an excessive amount, so that the phenomenon of air suction and liquid entrainment is generated.
When the air conditioner is in a high-temperature working condition such as refrigeration and the like, the liquid refrigerant and lubricating oil mixture sucked into the liquid storage tank through the air suction pipe 9 falls into the first liquid storage area 5 positioned below the liquid storage tank due to the self-weight action, the liquid refrigerant is less under the working condition, the liquid level formed at the lower part of the liquid storage tank is relatively low, the liquid refrigerant and lubricating oil mixture is concentrated in the first liquid storage area 5 at the moment, the accumulated mixture has higher viscosity and lacks necessary flowing power, at the moment, a single liquid storage cavity in the liquid storage tank is divided into the first liquid storage area 5 and the second liquid storage area 6 due to the arranged overflow device, the space of the first liquid storage area 5 is smaller than the original single liquid storage cavity, under the premise of the same liquid refrigerant and lubricating oil mixture, the liquid level of the first liquid storage area 5 is quickly lifted, at the moment, the dead weight of the liquid refrigerant and the lubricating oil mixture generates larger pressure difference along with the improvement of the height, so that the mobility of the liquid refrigerant and the lubricating oil mixture under high-temperature working conditions such as refrigeration and the like is improved, the size of a liquid return hole 3 in the connecting pipe 2 does not need to be adjusted, the size of the liquid return hole 3 is matched with the low-temperature working condition, and the liquid refrigerant and the lubricating oil mixture can enter the connecting pipe 2 without being too small by means of the power provided by the height pressure difference of the liquid refrigerant and the lubricating oil mixture, so that the internal components of the compressor are lubricated, and the phenomenon of air suction and liquid entrainment under the high-temperature working conditions such as refrigeration and the like is effectively prevented.
Therefore, due to the adoption of the liquid storage tank with the overflow structure, under the high-temperature working condition, the rising speed of the liquid refrigerant and lubricating oil mixture in the first liquid storage area 5 can be increased, and under the condition that the size of the liquid return hole 3 is not changed, the flowing power of the liquid refrigerant and lubricating oil mixture is positively correlated with the liquid level height and the liquid level difference of the liquid refrigerant and lubricating oil mixture; under the low temperature working condition, the liquid refrigerant higher than the preset liquid level height can be distributed to the second liquid storage area 6, so that the liquid level of the liquid refrigerant and the liquid lubricant mixture is kept unchanged in a certain time, the flowing power of the liquid refrigerant and the liquid lubricant mixture under the low temperature working condition is not too strong, the phenomenon of air suction and liquid carrying can be effectively prevented no matter under the high temperature working condition or the low temperature working condition, and the requirement of a wide-ring-temperature operation heat pump system is met.
The overflow structure may be of various types, and preferably, the overflow structure includes an overflow wall 4, the overflow wall 4 is a hollow structure, the overflow wall 4 is sleeved around the connecting pipe 2, and the side of the overflow wall 4 facing the insertion end of the connecting pipe of the housing 1 is connected to the housing 1. The overflow wall 4 may be designed in various forms, and in particular, a lower portion of the overflow wall 4 may be connected to an inner wall of the housing 1. As shown in fig. 1, the structure is a simple structure, and the lower end of the overflow wall 4 is directly connected to the inner wall of the casing 1, so that the first liquid storage area 5 and the second liquid storage area 6 are formed at the bottom inside the casing 1, which is particularly simple in process implementation; more preferably, the overflow wall 4 includes an upright portion 41 and a bent portion 42, one end of the bent portion 42 is connected to the upright portion 41, and the other end of the bent portion 42 is connected to the inner wall of the casing 1; of course, preferably, the overflow wall 4 is sleeved around the connecting pipe 2, and one side of the overflow wall 4 facing the connecting pipe insertion end of the housing 1 is connected to the connecting pipe 2, in this case, more preferably, the overflow wall 4 includes an upright portion 41 and a bent portion 42, one end of the bent portion 42 is connected to the upright portion 41, and the other end of the bent portion 42 is connected to the outer wall of the connecting pipe 2. The height of the upper edge of the overflow wall 4 should certainly not be higher than the upper air inlet of the connecting pipe 2, otherwise the function of the liquid storage tank will go out and remain, and therefore, it is not necessary to describe herein.
Preferably, the overflow wall 4 comprises a top opening, and when the liquid refrigerant and lubricant mixture is at a liquid level higher than the top opening, the liquid refrigerant and lubricant mixture is diverted from the top opening to the second liquid storage area 6; and/or, the overflow wall 4 is provided with an overflow hole 7, and when the liquid level of the liquid refrigerant and lubricating oil mixture is higher than the position of the overflow hole 7, the liquid refrigerant and lubricating oil mixture can be shunted from the first liquid storage area 5 to the second liquid storage area 6 under the action of pressure difference. In the technical scheme, when the air conditioner is in a low-temperature working condition (including a defrosting period) such as ultralow-temperature heating, the liquid level in the first liquid storage area 5 obviously rises, at the moment, because the overflow wall 4 is provided with the overflow hole 7, the aperture of the overflow hole 7 is relatively small, a liquid refrigerant and lubricating oil mixture under the working condition can extend into the second liquid storage area 6 through the overflow hole 7, so that the rise of the liquid level of the liquid refrigerant and lubricating oil mixture under the working condition is relatively slowed down, that is, the liquid refrigerant and lubricating oil mixture is ensured not to have too large liquidity due to too high liquid level, and the phenomenon of air suction and liquid entrainment caused by the fact that the liquid refrigerant and lubricating oil mixture enters the connecting pipe 2 in too large amount is effectively prevented; when the air conditioner is in a high-temperature working condition such as refrigeration and the like, the liquid refrigerant and lubricating oil mixture is viscous as described above, and the viscous characteristic causes that the liquid refrigerant and lubricating oil mixture cannot enter the second liquid storage area 6 through the overflow hole 7 with a small aperture, that is, the effect of the overflow hole 7 under the working condition is similar to zero.
Preferably, the overflow hole 7 is a circular hole, the aperture is preferably 0.8mm to 1.5mm, the overflow hole 7 with the aperture can ensure that the liquid refrigerant and the lubricating oil mixture under the low-temperature working condition can pass through the overflow hole 7, and the liquid refrigerant and the lubricating oil mixture under the high-temperature working condition can not pass through the overflow hole 7.
Preferably, the casing 1 is further provided with an air suction pipe 9, an air return baffle plate 8 is arranged in the casing 1 at a position opposite to the air suction pipe 9, the air return baffle 8 is connected with the inner wall of the shell 1, an air return hole 81 is arranged on the air return baffle 8, the air return hole 81 is positioned in the upper area of the first liquid storage area 5, so that the liquid refrigerant and lubricating oil mixture on the air return baffle 8 drops to the first liquid storage area 5 through the air return hole 81, the air return baffle 8 in the technical scheme prevents the liquid refrigerant and lubricating oil mixture from directly absorbing into the cylinder of the compressor by the air inlet end of the connecting pipe after entering the cavity of the liquid storage tank through the air suction pipe 9, and directly causing the phenomenon of air suction and liquid entrainment, meanwhile, the mixture of the liquid refrigerant and the lubricating oil is guided to directly drop into the first liquid storage area 5, so that the effect of avoiding the phenomenon of air suction and liquid entrainment is better.
Preferably, the air-return baffle 8 has a concave annular area on the circumference with the geometric center as the center, and the plurality of air-return holes 81 are uniformly distributed in the annular area, so as to ensure that the liquid refrigerant and lubricating oil mixture accumulated on the air-return baffle 8 can be smoothly guided into the annular area, and can uniformly drop into the first liquid storage area 5 below the annular area through the plurality of air-return holes 81.
