Description

Liquid baffle structure and evaporator of air conditioning equipment
Technical Field
The invention relates to the technical field of air conditioners, in particular to a liquid baffle structure and an evaporator of air conditioning equipment using the same.
Background
The air suction and liquid carrying are common problems in a centrifugal compressor unit, when the compressor sucks air and carries liquid, the power of the compressor is unstable, the current of a motor fluctuates greatly, the refrigerating capacity is unstable, and in addition, the compressor sucks air and carries liquid to operate for a long time, so that the impeller of the compressor is easily damaged. Suction entrainment is therefore a problem that must be avoided in centrifugal compressors.
At present, the working process of a centrifugal unit is that a refrigerant is throttled by an electronic expansion valve from a condenser, enters an evaporator to be evaporated, and then enters a gas suction port of a compressor from a gas outlet of the evaporator. Because the liquid refrigerant and the heat exchange tube become gaseous after heat exchange and evaporation, the gaseous refrigerant often can carry part of the liquid refrigerant when rising towards the air suction port 1 of the compressor, therefore, at present, a gas-liquid separation device is generally arranged at the air outlet of the evaporator or the air suction port of the compressor. When the gaseous refrigerant is discharged from the air outlet of the evaporator or enters the air suction port of the compressor, the gaseous refrigerant and the liquid refrigerant are separated by the gas-liquid separation device. As shown in fig. 1, the gas-liquid separation device in the current centrifugal unit comprises a gas-liquid separation assembly 2 and a liquid baffle 3. When the gas-liquid separation component works, when gaseous refrigerant carrying liquid refrigerant rises, the gaseous refrigerant firstly passes through the gas-liquid separation component 2 with the stainless steel wire mesh, the liquid refrigerant is separated for the first time, then reaches the liquid baffle plate 3 shown in figure 1, and stays on the liquid baffle plate 3 through baffling the liquid refrigerant, and the gaseous refrigerant bypasses the liquid baffle plate and enters the air suction port 1 of the compressor. Under normal operating mode, through the combined action of gas-liquid separation subassembly 2 and fender liquid board 3, most liquid refrigerant in the gaseous refrigerant is separated out, can not be along with gaseous refrigerant by in the suction port 1 of compressor.
As the centrifuge is generally required to operate under the working condition of 7-30 ℃ or 7-32 ℃, and the unit can be debugged under the working condition when the unit is delivered from a factory for testing, the possibility of air absorption with liquid is eliminated. However, in the actual use process of the user, the refrigerant may deviate from the design working condition and operate under the working condition with large pressure difference such as 7-35 ℃, under the working condition with large pressure difference, the amount of the refrigerant in the evaporator is increased, and the conventional gas-liquid separation device cannot completely separate the liquid refrigerant, so that the air absorption and liquid entrainment of the unit are caused. In addition, if the control parameter of the electronic expansion valve is set unreasonably, the opening degree of the electronic expansion valve is larger, and the occurrence of air suction and liquid entrainment can also be caused. In addition, if the unit runs for a long time, lubricating oil of the unit leaks into the refrigerant, and meanwhile, oil is not returned in time, and the unit is also caused to absorb air and carry liquid due to large oil content in the refrigerant.
In summary, when the gas-liquid separation device in the prior art works under abnormal working conditions, the situation that the centrifugal unit sucks air and carries liquid cannot be avoided, and the gas-liquid separation device is difficult to adapt to environments with various complex working conditions.

Detailed Description
To further explain the technical means and effects of the present invention adopted to achieve the predetermined object, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
As shown in fig. 2 to 4, an embodiment of the present invention provides a liquid barrier structure, including:
the baffle plate assembly 100 comprises at least two baffle plates 10 which are connected with each other and arranged in parallel, and a gap is formed between every two adjacent baffle plates 10. Each baffle 10 is provided with a plurality of small holes 11. The baffle plate assembly 100 is arranged at the gas inlet and/or outlet of an external device in a blocking way, for example, in an air-conditioning refrigeration/heating system, the baffle plate assembly 100 is arranged at the gas outlet of an evaporator or the suction port of a compressor, and when gaseous substances enter the gas inlet and/or outlet through the small holes 11, at least part of the liquid substances entrained therein can be blocked at the front end of the gas inlet and/or outlet by the baffle plate assembly 100.
The operation of the two baffles 10 will now be described by way of example. As shown in fig. 5, it is assumed that the upper baffle is a first baffle 12 having a first small hole 121; the lower baffle is a second baffle 13 having a second aperture 131. The gas entrained with the liquid first passes through the second small holes 131 of the second baffle 13 located below, part of the liquid therein being blocked by the second baffle 13 from passing through said second small holes 131 with the gas, and another part of the liquid therein passing through said second small holes 131 with the gas. Due to the gap between the first baffle 12 and the second baffle 13 and the fluidity of the gas, then, when the gas passing through the second small holes 131 continues to move upwards, a part of the gas encounters the first baffle 12 located above, the liquid contained therein is blocked by the first baffle 12 again, and another part of the gas passes through the first small holes 121 of the first baffle 12. So that the liquid entrained in the gas is gradually blocked by the layers of baffles 10 of the baffle assembly 100 at the front end of the outlet/inlet of the external device. Obviously, the more the number of layers of the baffle 10 is, the better the barrier effect is.
According to the technical scheme, the baffle plate assembly is arranged at the gas inlet and/or outlet of the external equipment, and due to the fact that the plurality of small holes are formed in each baffle plate of the baffle plate assembly, when gaseous substances enter the gas inlet and/or outlet through the plurality of small holes, at least part of liquid substances entrained in the gaseous substances can be blocked at the front end of the gas inlet and/or outlet by the baffle plate assembly. And the baffle plate assembly comprises at least two baffle plates which are fixedly connected with each other and are arranged in parallel, and a gap is formed between every two adjacent baffle plates, so that liquid can be blocked by each layer of baffle plate when the gas passes through the baffle plate assembly, and further, the liquid substance carried by the gaseous substance is blocked at the front end of the gas inlet and/or outlet. Thereby effectively reducing the condition that the air suction of the centrifugal unit is carried with the liquid, improving the working stability of the centrifugal unit, and being suitable for the environment with various complex working conditions.
Preferably, as shown in fig. 2 to 4, the small holes on two adjacent baffles can be staggered. As shown in fig. 5, also, it is assumed that the upper baffle is a first baffle 12 having a first small hole 121; the lower baffle is a second baffle 13 having a second aperture 131. Because the first small holes 121 and the second small holes 131 are staggered, i.e. do not correspond up and down, after passing through the second small holes 131 of the second baffle 13 below, the gas carrying part of the liquid cannot directly pass through the first small holes 121 of the first baffle 12 above, but continues to detour upwards to and through the first small holes 121 of the first baffle 12 above through the gap. In the course of the detour, a large part of the liquid in the gas is blocked by the first baffle 12, and a very small amount of the gas with the liquid is discharged upwards from the first small holes 121 of the first baffle 12. If more baffles 10 are provided, the liquid in the gas is further reduced by the layer-by-layer separation.
Preferably, as shown in fig. 2 to 4, the plurality of small holes 11 are arranged uniformly in a first direction, and are formed in a plurality of columns parallel to each other in a second direction perpendicular to the first direction. For example, when the baffle 10 is rectangular, the first direction may be along the length or width of the baffle 10, and the second direction may be perpendicular to the first direction. As long as two adjacent baffle on a plurality of the column is parallel to each other and the interval is staggeredly arranged, just so can guarantee to stagger between the aperture 11 of two adjacent baffles 10.
Preferably, as shown in fig. 2 to 5, when the gas inlet/outlet is provided on an arc surface, the baffle 10 may be an arc plate adapted to the shape of the gas inlet/outlet. For example, the air outlet of the evaporator is arranged on the side wall of the cylindrical evaporator, so that the air outlet of the evaporator has a certain radian, and therefore, the baffle 10 can also be correspondingly curved to adapt to the shape of the air outlet of the evaporator, so that the air outlet of the evaporator has a better liquid blocking effect.
Preferably, as shown in fig. 2-4, the flapper assembly 100 may be a movable structure that is movable from a first position to a second position. Wherein the first position is a non-operative position remote from the gas inlet and/or outlet and the second position is an operative position at the gas inlet and/or outlet.
When the baffle plate assembly 100 moves to the first position (shown in fig. 6), the gas passing through the gas inlet and/or outlet is subjected to gas-liquid separation; the baffle assembly 100, when moved to the second position (shown in fig. 7), does not effect a gas-liquid separation of the gas to be passed through the gas inlet and/or outlet.
Preferably, as shown in fig. 2 to 4, the liquid baffle structure may further include a moving mechanism 20. The moving mechanism 20 may be connected to the shutter assembly 100, and the moving mechanism 20 moves the shutter assembly 100 between the first position and the second position.
Preferably, as shown in fig. 2 to 4, the moving mechanism 20 may include a driving unit 23 and an executing unit 22 connected to each other. The execution unit 23 is connected to the baffle assembly 100, and the driving unit 23 drives the execution unit 22 to move so as to drive the baffle assembly 100 to move. The driving unit 23 may be an electric driving device, such as a motor, an electric actuator, etc. The drive device may be a hydraulic drive power device such as a hydraulic motor, a pneumatic drive power device, or a manual drive device, such as a hand-operated mechanical structure.
Preferably, as shown in fig. 2 to 4, the moving mechanism 20 may further include a connection unit 21. The actuating unit 23 and the barrier assembly 100 are connected by the connecting unit 21. For example, one end of the connection unit 21 may be connected to the barrier assembly 100. The other end of the connection unit 21 is connected to the execution unit 22. Thus, when the execution unit 22 is operated, the connection unit 21 is moved to move the baffle assembly 100. The connection unit 21 and the execution unit 22 may be connected in a hinged manner, a rotatable connection, or a fixed connection (such as welding or hinge connection). The specific structure of the moving mechanism 20 is determined. For example, when the actuating unit 22 of the moving mechanism 20 is an air cylinder, the connecting unit 21 can fix a piston rod of the air cylinder and the baffle 10 together, so that the air cylinder can drive (push or pull) the baffle 10 to move.
Different from the above-mentioned moving manner of the air cylinder, a specific structure form of the slider-crank mechanism composed of the moving mechanism 20 and the shutter assembly 100 will be described.
As shown in fig. 2 to 4, the barrier assembly 100 corresponds to a slide block, the actuating unit 22 of the moving mechanism 20 may include a crank 221 and a connecting rod 222 hinged to each other, the connecting rod 222 is hinged to the barrier assembly 100 (slide block), the driving unit 23 is connected to the crank 221 and drives the crank 221 to rotate, and when the crank 221 rotates, the connecting rod 222 is driven to make the slide block (barrier assembly 100) perform a linear reciprocating motion.
The baffle assembly 100 (sliding block) may be fixedly connected to the connecting unit 21, and the connecting rod 222 may be hinged to the baffle assembly 100 (sliding block) by being hinged to the connecting unit 21. The crank 221 can rotate between 0-360 degrees by any angle. For example, the crank 221 may rotate from 0 degree to 180 degrees, and then return from 180 degrees to 0 degree to realize the reciprocating motion of the slider; the reciprocating motion of the slide block can also be realized by rotating from 0 degree to 180 degrees and then rotating from 180 degrees to 360 degrees. When the crank 221 rotates, the slide block (the baffle assembly 100) is driven by the connecting rod 222 to move from the first position to the second position, and then returns to the first position from the second position. The skilled person can implement the movement of the slider (the baffle plate assembly 100) by using any implementation form of a crank-slider mechanism according to actual needs, and the invention is not limited in particular.
Fig. 2 shows the crank 221 rotated to 180 degrees with respect to the connecting rod 222, wherein the slide (baffle assembly 100) is in a second, working position; FIG. 3 is an intermediate transition condition when the crank 221 is rotated 90 degrees to the connecting rod 222, with the slide (flapper assembly 100) between the first position and the second position; fig. 4 shows the situation when the crank 221 is rotated to 0 degrees with respect to the connecting rod 222, i.e. when the crank 21 is coincident with the connecting rod 222, and the slide (shutter assembly 100) is in the first, non-operating position.
Of course, the moving mechanism 20 may have other structures, and those skilled in the art can design it flexibly according to the needs. And is not particularly limited herein.

Preferably, the evaporator may further comprise a primary separation device 420. The primary separating apparatus 420 is disposed at the gas outlet 310 of the evaporator body 300, and the primary separating apparatus 420 is upstream of the liquid baffle structure 410 in a gas discharge direction.
The gas (gaseous refrigerant) with entrained liquid (liquid refrigerant) is first subjected to a preliminary filtration by a primary separation device 420 to separate a portion of the liquid from the gas before entering the outlet 310 of the evaporator body. The separated gas is further filtered by the liquid baffle plate structure 410, so that the gas purity is higher, the gas suction and liquid carrying conditions of the centrifuge unit are reduced, the working stability of the centrifuge unit is improved, and the centrifuge unit can adapt to various environments with complex working conditions.
Preferably, the primary separating device 420 may include a primary separating unit 421 and a secondary separating unit 422 which are sequentially disposed in a gas discharge direction. The liquid baffle structure 410 is downstream of the secondary separation unit 422. The gas filtering sequence is from the first-stage separation unit 421, to the second-stage separation unit 422, to the liquid baffle structure 410, and finally to the outlet 310 of the evaporator body. The primary separation unit 421 may be a stainless steel wire mesh. The secondary separation unit 422 may be a liquid baffle 3 shown in fig. 1, which is structured as shown in fig. 8, wherein the secondary separation unit 422 may include a liquid baffle body portion having a droplet blocking region configured to enable droplets condensed thereon to be collected to a droplet falling portion lower than an area around the droplet falling portion (detailed structure is described in patent No. CN204438616U, entitled "liquid baffle structure and evaporator of air conditioning equipment"). Fig. 8 is merely one form of the secondary separation unit 422, and other forms are possible, and are not limited to this.
