Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to an air intake pipe structure, a liquid distributor and a compressor. Background Art

[0002] At present, a liquid separator is usually provided at the air inlet end of the compressor to separate the liquid refrigerant from the gaseous refrigerant entering the compressor to prevent the liquid refrigerant from causing liquid hammer on the cylinder of the compressor. After the refrigerant passes through the liquid separator, the gaseous refrigerant can enter the compression cylinder of the compressor, and the liquid refrigerant is stored in the liquid storage chamber of the liquid separator and flows back to the compressor through the oil return hole in the liquid separator to meet the refrigerant circulation volume of the air-conditioning system.

[0003] Firstly, in the prior art, the compressor will have different refrigerant return volume requirements as it operates under different working conditions. Under the working conditions of low-temperature heating and maximum cooling, the liquid storage chamber of the liquid distributor is required to store a small amount of refrigerant to give full play to the system capacity and allow as much refrigerant as possible to participate in the circulation process to meet the maximum cooling and low-temperature heating capacity requirements. Under the working conditions of rated cooling and low-temperature intermediate cooling, a certain amount of refrigerant is required to be stored in the liquid storage chamber of the liquid distributor to match the overall energy efficiency of the air-conditioning system. However, the liquid distributor in the prior art cannot meet the requirements of matching the refrigerant return according to different working conditions.

[0004] Secondly, in the air-conditioning system, there will be obvious air-intake liquid in low-temperature heating conditions or when starting after standing still. Since the volume of the liquid separator is limited by the size of the air-conditioning system, the current compressor liquid separator has poor gas-liquid separation under severe air-intake liquid conditions. It is necessary to strengthen the ability of the liquid separator to separate liquid refrigerant as much as possible within a limited space. Summary of the invention

DETAILED DESCRIPTION

[0047] 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.

[0048] like Figure 1-Figure 9 As shown, the present invention provides an air intake pipe structure for connecting a liquid separator 2 and a compressor housing 1 to deliver the gaseous refrigerant that has completed gas-liquid separation in the liquid separator 2 into the compressor; specifically, the air intake pipe structure of the present invention includes an air intake pipe 3 and a flow path regulating component; wherein:

[0049] One end of the air intake pipe 3 is connected to the air intake port of the device to be supplied with air, so as to supply the gaseous refrigerant; it should be noted that, in this embodiment, the device to be supplied with air is a compressor; one end of the air intake pipe 3 is connected to the air intake port of the compressor housing 1;

[0050] The other end of the air inlet pipe 3 is arranged in the supply cavity to deliver the gaseous refrigerant to the air inlet; it should be noted that the supply cavity here is the liquid storage cavity 5 of the liquid separator 2, that is, the other end of the air inlet pipe 3 is located in the liquid storage cavity 5 of the liquid separator 2, and the gaseous refrigerant separated by gas and liquid enters the compressor through the air inlet pipe 3;

[0051] like Figure 1 and Figure 2 As shown, the flow path regulating component is arranged on the air inlet pipe 3 located in the supply cavity to adjust the length of the gaseous refrigerant flow path. In this embodiment, the flow path regulating component is arranged on the air inlet pipe 3 in the liquid storage cavity 5, so as to adjust the overall length of the air inlet pipe 3, and also adjust the length of the flow path of the gaseous refrigerant. The flow path regulating component can realize the switching between the long flow path and the short flow path of the gaseous refrigerant.

[0052] The air intake pipe structure provided by the present invention can adjust the flow length of the gaseous refrigerant in the air intake pipe 3 through the flow path adjustment component, and can realize the control of the refrigerant reflux capacity of the liquid separator 2 under different working conditions, thereby solving the problem that the liquid separator 2 in the prior art cannot meet the requirements of matching the refrigerant reflux according to different working conditions.

[0053] like Figure 1-Figure 9 As shown, as an optional embodiment of the present invention, the flow path regulating component includes an extension pipe 7, a blocking member 4, a first air inlet 31, a second air inlet 32, and a control member; wherein:

[0054] The first air inlet hole 31 and the second air inlet hole 32 are respectively opened on different side walls of the air inlet pipe 3, and there is a gap between the first air inlet hole 31 and the second air inlet hole 32; specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the first air inlet hole 31 is located at the upper part, close to the end of the air inlet pipe 3, and the second air inlet hole 32 is located below the first air inlet hole 31, away from the end of the air inlet pipe 3; a blocking member 4 is provided on the inner wall of the air inlet pipe 3 between the first air inlet hole 31 and the second air inlet hole 32;

[0055] One end of the extension pipe 7 is connected to the end of the air inlet pipe 3, and the other end is connected to the second air inlet hole 32;

[0056] The blocking member 4 is movably disposed between the first air inlet hole 31 and the second air inlet hole 32;

[0057] The control member is in transmission connection with the blocking member 4, and can drive the blocking member 4 to block the inner cavity of the air inlet pipe 3 below the first air inlet hole 31 or block the position of the second air inlet hole 32. Figure 1 When the first air inlet hole 31 and the air inlet pipe 3 are in the position, the blocking member 4 closes the passage between the first air inlet hole 31 and the air inlet pipe 3, so that the gaseous refrigerant can only enter the air inlet pipe 3 through the long flow channel of the extension pipe 7 and then through the second air inlet hole 32. At this time, the path for the refrigerant in the liquid reservoir to enter the compressor is increased, thereby greatly improving the liquid separation ability of the liquid distributor 2; and greatly improving the reliability and service life of the compressor. This innovation makes the liquid distributor 2 more suitable for the application requirements of high-performance compressors and complex refrigeration systems.

[0058] like Figure 2 As shown, when the blocking member 4 is in Figure 2 position, the blocking member 4 blocks the second air inlet hole 32, so that the gaseous refrigerant enters through the first air inlet hole 31 and directly flows into the compressor through the air inlet pipe 3, shortening the refrigerant flow path and being able to control the refrigerant reflux capacity of the liquid distributor 2 under different working conditions.

[0059] Taking into account the liquid separation effect, in this embodiment, Figure 3 As shown, the diameter of the extension pipe 7 is smaller than that of the intake pipe 3. As an optional embodiment of the present invention, the extension pipe 7 is made of the same specification pipe to form an equal diameter structure. Of course, the extension pipe 7 can also be set to an unequal diameter structure.

[0060] like Figure 4 As shown, the extension pipe 7 includes at least two straight pipes, and all the straight pipes are connected end to end to form an L-shaped extension pipe 7.

[0061] Specifically, in this embodiment, the extension pipe 7 is composed of five straight pipes, which are arranged in sequence. The first straight pipe is vertically connected to the end of the air inlet pipe 3, and the fifth straight pipe is connected to the second air inlet hole 32. It should be noted that Figure 1 and Figure 2As shown, the length of each straight pipe section can be determined according to the specifications of the liquid storage chamber 5, and the flow length can be increased as much as possible, or the total length can be calculated according to the design, and then reasonably set according to the specifications of the liquid storage chamber 5. Considering that this part needs to be tested and calculated, the present invention does not make specific details, as long as the extension pipe 7 can be set to increase the flow of the gaseous refrigerant, and the specific straight pipe setting structure is not specifically limited in the present invention.

[0062] like Figure 7 As shown, as another optional embodiment of the present invention, in order to further extend the flow path in a limited space, in this embodiment, the extension tube 7 includes an upper liquid separation channel 8 and a lower liquid separation channel 9 arranged in sequence; the upper liquid separation channel 8 is a spiral structure, and this structural arrangement can increase the flow path as much as possible in a limited space; the lower liquid separation channel 9 is a straight tube structure, specifically, as shown in FIG. Figure 7 As shown, the lower liquid separation channel 9 includes three straight tubes, the first straight tube is connected to the upper liquid separation channel 8, and the third straight tube is connected to the second air inlet 32. It should be noted that the lower liquid separation channel 9 can also be set to a spiral structure as long as it is staggered with the upper liquid separation channel 8 in space.

[0063] When the air conditioning system is in low temperature heating condition or started after being left still, there will be obvious air intake with liquid. Since the volume of the liquid separator 2 is limited by the space size of the air conditioning system, the current compressor liquid separator 2 is not good at gas-liquid separation in the condition of serious air intake with liquid. In order to further improve the gas-liquid separation effect, in this embodiment, if Figure 1-Figure 6 As shown, at least one liquid separator ring 6 is arranged in the extension pipe 7, and the liquid separator ring 6 can effectively separate the liquid amount of the refrigerant passing through to avoid damage to the compressor pump body caused by excessive liquid refrigerant.

[0064] It should be noted that, in order to ensure the liquid separation effect, the number of liquid separation rings 6 is at least 2, and should be more than 2 to achieve a better liquid separation effect. All liquid separation rings 6 can be evenly distributed in the extension tube 7.

[0065] By providing at least one liquid separator ring 6, gas-liquid separation can be further performed, thereby solving the problem of poor gas-liquid separation in the compressor separator 2 leading to wet compression of the compressor and reduced refrigeration capacity, and solving the problem of liquid inhalation and liquid hammer in the compressor leading to damage to the compressor pump body parts.

[0066] In order to ensure the liquid separation effect, the distance L between two adjacent liquid separation rings 6 is the same; in order to achieve a better effect of separating the liquid refrigerant, the distance L between the liquid separation rings 6 satisfies the following formula:

[0067] 0.5D≤L≤2D, wherein D is the diameter of the liquid separator ring 6.

[0068] Furthermore, the liquid separation ring 6 is provided with a first liquid separation hole 61 and a second liquid separation hole 62; wherein:

[0069] The first liquid separation hole 61 is arranged at the center of the liquid separation ring 6;

[0070] There are a plurality of second liquid separation holes 62 , which are located outside the first liquid separation holes 61 and are arranged along the circumference of the liquid separation ring 6 .

[0071] As a further improvement of the present invention, the areas of the first liquid separation hole 61 and the second liquid separation hole 62 should satisfy the following formula:

[0072] n1*S1+n2*S2≥0.3π(D / 2) 2 ; Wherein: n1 is the number of second liquid separation holes 62; n2 is the number of first liquid separation holes 61; S1 is the area of ​​a single second liquid separation hole 62; S2 is the area of ​​a single first liquid separation hole 61; D is the diameter of the liquid separation ring 6.

[0073] like Figure 8 and Fig. 9 As shown, the blocking member 4 includes a connecting end 41, a blocking end 42, and an electrically-memory metal sheet 43; wherein:

[0074] The connecting end 41 is fixedly connected to the inner wall of the air inlet pipe 3;

[0075] One end of the blocking end 42 is hinged to the connecting end 41;

[0076] The electrical memory metal sheet 43 is disposed between the connecting end 41 and the blocking end 42 .

[0077] By energizing the memory metal sheet 43 to deform, different flow paths of the refrigerant in the liquid distributor 2 are further realized, thereby greatly improving the liquid separation capacity of the liquid distributor 2 and greatly improving the reliability and service life of the compressor. This innovation makes the liquid distributor 2 more suitable for the application requirements of high-performance compressors and complex refrigeration systems.

[0078] The present invention provides a liquid distributor 2, comprising a liquid storage chamber 5 and an air intake pipe structure; one end of the air intake pipe structure is arranged in the liquid storage chamber 5, and the other end is connected to the air intake port of the device to be supplied with air.

[0079] In this embodiment, the device to be fed with air is a compressor.

[0080] The compressor control module has a preset current value, which should vary according to the size of the compressor displacement; severe liquid carrying in the working condition will cause the current to increase, and the limit value can be set according to the normal current of the working condition. If it exceeds a certain limit value, the blocking member 4 switches to the blocking state.

[0081] The liquid separator 2 provided by the present invention can accurately control the gas-liquid flow path inside the liquid separator 2 through unique design and structural innovation. Compared with the traditional liquid separator 2, the liquid separator 2 can effectively utilize the energized memory metal sheet 43 to seal the plug 4. The plug 4 is connected in series with the power supply circuit of the body. When the current in the compressor circuit is less than the preset current value, the plug 4 is in the open state. When the current in the compressor circuit is greater than or equal to the preset current value, the plug 4 switches to the blocked state. The different flow paths of the refrigerant in the liquid separator 2 are further realized, thereby greatly improving the liquid separation ability of the liquid separator 2; and greatly improving the reliability and service life of the compressor. This innovation makes the liquid separator 2 more suitable for the application requirements of high-performance compressors and complex refrigeration systems.

[0082] The present invention provides a compressor, comprising a compressor housing 1 and a liquid separator 2; the liquid separator 2 is mounted on the compressor housing 1.

[0083] In this embodiment, the liquid distributor 2 in the compressor has a liquid storage chamber 5, an air inlet pipe 3, and a blocking member 4; the other end of the air inlet pipe 3 is connected to the compressor housing 1, and the other end is located in the liquid storage chamber 5. The side wall of the air inlet pipe 3 located in the liquid storage chamber 5 is provided with a first air inlet hole 31 and a second air inlet hole 32. The gaseous refrigerant in the liquid storage chamber 5 enters the air inlet pipe 3 through the first air inlet hole 31 and then enters the compressor; the blocking member 4 is arranged in the air inlet pipe 3, between the first air inlet hole 31 and the second air inlet hole 32, and the blocking member 4 has a relatively set blocking state and an open state. When the blocking member 4 is in the blocking state, the refrigerant flow route in the liquid storage chamber 5 is as follows Figure 1 , the refrigerant enters from the first air inlet hole 31, passes through the extended pipe 7, enters the straight pipe section of the air inlet pipe 3 from the second air inlet hole 32, and enters the compressor pump body; at this time, the path of the refrigerant in the liquid storage chamber 5 entering the compressor is increased, and a liquid separator ring 6 (such as Figure 3 ), the liquid separator ring 6 can effectively separate the liquid content of the refrigerant, avoiding damage to the compressor pump body caused by excessive liquid refrigerant. Figure 3 , assuming that the diameter of the liquid separator ring 6 is D, and the intervals between the multiple liquid separator rings 6 are the same, and the interval distance is L, in order to achieve a better effect of separating the liquid refrigerant, 0.5D≤L≤2D should be satisfied; Figure 5 As shown, the liquid separation ring 6 is provided with a plurality of liquid separation holes, namely, the first liquid separation hole 61 and the second liquid separation hole 62; assuming that the number of the second liquid separation holes 62 is n1, and the area is S1, and the number of the first liquid separation holes 61 is n2, and the area is S2, if the total area of ​​the liquid separation holes is too small, it will affect the suction smoothness of the compressor. To ensure the suction smoothness while ensuring the liquid separation effect, the design of all liquid separation holes should satisfy n1* S1+ n2* S2≥0.3π (D / 2) 2 .

[0084] When the blocking member 4 is in the open state, the refrigerant flow path in the liquid storage chamber 5 is as follows: Figure 2 The refrigerant enters from the first air inlet hole 31, directly enters the straight section of the air inlet pipe 3, and enters the compressor pump body; at this time, the path of the refrigerant in the liquid storage chamber 5 entering the compressor is shortened, so that as much refrigerant as possible can participate in the circulation process and give full play to the system capacity.

[0085] The blocking member 4 is connected in series with the power supply circuit of the compressor body. When the current in the compressor circuit is less than the preset current value, the blocking member 4 is in the open state. When the current in the compressor circuit is greater than or equal to the preset current value, the blocking member 4 switches to the blocking state.

[0086] The plugging member 4 has a connecting end 41, a plugging end 42, and an electrically powered memory metal sheet 43 that are arranged opposite to each other. The connecting end 41 of the plugging member 4 is fixedly connected to the side wall of the air inlet pipe 3. The plugging end 42 has a hinge hole that is hinged to the connecting end 41. The electrically powered memory metal sheet 43 is arranged between the connecting end 41 and the plugging end 42. Figure 8 The two ends of the energized memory metal sheet 43 will maintain an angle of 180 degrees when energized, so as to ensure that the blocking member 4 effectively separates the first air inlet 31 and the second air inlet 32, so that the refrigerant can enter the compressor after passing through the extended pipe 7. Fig. 9 As shown, in the non-powered state, the two ends of the powered memory metal sheet 43 will maintain a 90-degree angle, thereby effectively blocking the second air inlet 32, allowing as much refrigerant as possible to enter the compressor to participate in the compression cycle, and reducing the amount of refrigerant in the liquid reservoir.

[0087] The principle of separating the gas-liquid two-phase refrigerant by the liquid separator 2 in Example 2 is the same as that in Example 1. The difference between Example 2 and Example 1 is only in the structure of the extension tube 7. In this embodiment, the extension tube 7 includes an upper liquid separation channel 8 and a lower liquid separation channel 9. Figure 7 , the upper liquid separation channel 8 can be set to an axial spiral shape to increase the flow path of the refrigerant, and the liquid refrigerant is affected by its own weight, and the liquid separation ability will be better;

[0088] It should be noted that the upper liquid separation channel 8 and the lower liquid separation channel 9 can both be arranged in a spiral shape, as long as they are staggered in space.
