Description

Technical Field

[0001] This utility model relates to the field of scroll compressor technology, specifically to a scroll assembly, a scroll compressor, and an air conditioner. Background Technology

[0002] Currently, with the expansion of the applicable range of heat pump cycle systems, traditional jet scroll compressors need to meet heating requirements under low ambient temperature conditions, especially for heating in extremely low ambient temperatures. However, the effect of jet enthalpy enhancement is currently limited, and how to further improve heating capacity is a problem to be solved in related fields. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, the present invention proposes a scroll assembly, comprising: a stationary scroll; a moving scroll, which together with the stationary scroll forms a plurality of compression chambers, the plurality of compression chambers including a first compression chamber and a second compression chamber, the moving scroll including moving scroll teeth, the first compression chamber and the second compression chamber being located on opposite sides of the moving scroll teeth along the radial direction of the moving scroll, the first compression chamber facing a first region on the stationary scroll when the first compression chamber is closed after intake, and the second compression chamber facing a second region on the stationary scroll when the second compression chamber is closed after intake; and an enthalpy-increasing air intake group disposed on the stationary scroll, the enthalpy-increasing air intake group being used to increase enthalpy and supplement air into the first compression chamber and the second compression chamber, at least a portion of the enthalpy-increasing air intake group being located in the first region and the second region.

[0005] A first compression chamber and a second compression chamber are formed between the stationary volute and the moving volute. Since the first compression chamber and the second compression chamber are located on both sides of the moving volute along the radial direction of the moving volute, that is, the first compression chamber is the outer compression chamber of the moving volute and the second compression chamber is the inner compression chamber of the moving volute, or the first compression chamber is the inner compression chamber of the moving volute and the second compression chamber is the outer compression chamber of the moving volute.

[0006] One of the first and second compression chambers will draw in air first; in this embodiment, the first compression chamber will draw in air first for illustrative purposes. When the first compression chamber has completed its intake and just closed, its location corresponds to the first region on the stationary scroll plate. After the first compression chamber closes, as the scroll compressor continues to operate, the second compression chamber begins to draw in air. When the second compression chamber has completed its intake and just closed, its location corresponds to the second region on the stationary scroll plate.

[0007] When the first compression chamber has finished intake and just closed, the gas inside the first compression chamber has not yet been compressed, or has just begun to be compressed, and the pressure inside the first compression chamber is relatively low. Similarly, when the second compression chamber has finished intake and just closed, the gas inside the second compression chamber has not yet been compressed, or has just begun to be compressed, and the pressure inside the second compression chamber is relatively low.

[0008] The enthalpy-enhancing intake assembly can replenish gaseous refrigerant into the first and second compression chambers. The gaseous refrigerant replenished into the first and second compression chambers merges with the gas being compressed. Compared with compressors that do not perform jet enthalpy enhancement, the scroll compressor in this scheme has a larger enthalpy difference on the evaporator side, which is beneficial to improving the heating capacity.

[0009] The enthalpy-increasing air intake group is set on the stationary scroll plate, and it is located in the first and second regions. Therefore, the enthalpy-increasing air intake group corresponds to the position with lower pressure in the first and second compression chambers. Under the condition of constant external air intake pressure, the enthalpy-increasing air intake group can more easily add enthalpy to the first and second compression chambers, thereby increasing the amount of air added to the first and second compression chambers per unit time. As the amount of air added increases, the heating capacity of the scroll compressor can be further improved, which is conducive to improving the heating capacity of the air conditioner per unit time.

[0010] In addition, the vortex disk assembly according to the above-mentioned technical solution provided by this utility model may also have the following additional technical features:

[0011] In some technical solutions, optionally, a third region is provided on the stationary vortex disk, which is the overlapping region of the first region and the second region, and at least a part of the enthalpy-increasing intake group is located in the third region.

[0012] The first and second regions have overlapping areas, which are designated as the third region. The enthalpy-increasing intake group is located within the third region.

[0013] The spaces occupied by the first compression chamber and the second compression chamber when air intake is complete overlap, and this overlapping space corresponds to the third region. These overlapping spaces have a relatively large length or width, resulting in lower intake resistance. Therefore, when the enthalpy-enhancing intake assembly is located within the third region, it is easier for the enthalpy-enhancing intake assembly to replenish the first and second compression chambers, increasing the amount of air replenished to the first and second compression chambers per unit time.

[0014] In some technical solutions, optionally, the maximum width of the third region along the radial direction of the moving scroll is W; straight lines L1 and L2 are set to extend radially along the moving scroll, the length of straight line L1 in the third region is W, the length of straight line L2 in the third region is 0.5W, and the enthalpy-enhancing intake group is located between straight lines L1 and L2.

[0015] Along the radial direction of the moving scroll, the wider the third region, the smaller the intake resistance. Therefore, the position of the enthalpy-increasing intake assembly needs to be selected with reference to the width of the third region.

[0016] Both lines L1 and L2 extend radially along the moving vortex. A portion of line L1 lies within the third region, and the length of this portion of line L1 within the third region is W. Since the maximum width of the third region along the radial direction of the moving vortex is also W, line L1 passes through the position with the maximum width within the third region. Similarly, a portion of line L2 lies within the third region, and the length of this portion of line L2 within the third region is 0.5W. Therefore, line L2 passes through the position at half the maximum width within the third region.

[0017] The enthalpy-enhancing intake assembly is positioned between straight lines L1 and L2, thus placing it within the wider area of ​​the third region. This space has lower intake resistance, making it easier for the enthalpy-enhancing intake assembly to replenish the first and second compression chambers with enthalpy, thereby increasing the amount of replenished air supplied to the first and second compression chambers per unit time.

[0018] In some technical solutions, optionally, the enthalpy-increasing air intake group includes: a first air intake port, disposed on a first region, the first air intake port being used to add enthalpy-increasing air to the first compression chamber; and a second air intake port, disposed on a second region, the second air intake port being used to add enthalpy-increasing air to the second compression chamber.

[0019] The first air inlet can supply air to the first compression chamber, and the second air inlet can supply air to the second compression chamber. Therefore, the first compression chamber and the second compression chamber can be supplied with air independently. For example, the first compression chamber can be supplied with air through the first air inlet first, and then the second compression chamber can be supplied with air through the second air inlet, or the first air inlet and the second air inlet can supply air simultaneously.

[0020] With gas replenishment structures installed in both the first and second compression chambers, different enthalpy increases can be achieved in the first and second compression chambers. The enthalpy increase can be adjusted according to usage requirements, which helps to improve the heating capacity of the air conditioner.

[0021] In some technical solutions, optionally, an air intake channel is provided on the stationary vortex disk, and both the first air intake port and the second air intake port are connected to the air intake channel.

[0022] An air intake channel is machined on the stationary vortex disk. Since both the first and second air intake holes are connected to the air intake channel, the gas in the air intake channel can be diverted to the first and second air intake holes.

[0023] The jet enthalpy enhancement structure in this scheme achieves dual-channel air replenishment by setting the first air inlet and the second air inlet as two independent jet structures. On this basis, the first air inlet and the second air inlet share a common air inlet channel, which can achieve the function of simultaneous air replenishment. Compared with the method of sequentially replenishing different cavities with air inlets, the structure of the first air inlet and the second air inlet sharing a common air inlet channel in this scheme can reduce the air replenishment frequency and improve the air replenishment efficiency.

[0024] In some technical solutions, optionally, the number of first air inlets is at least two, and / or the number of second air inlets is at least two.

[0025] The first air inlet is used to replenish air into the first compression chamber. Due to the size limitation of the first compression chamber, the diameter of the first air inlet cannot be too large. Therefore, by increasing the number of first air inlets, rapid air replenishment to the first compression chamber can be achieved.

[0026] Similarly, the second air inlet is used to replenish air into the second compression chamber. Due to the size limitation of the second compression chamber, the diameter of the second air inlet cannot be too large. Therefore, by increasing the number of second air inlets, rapid air replenishment to the second compression chamber can be achieved.

[0027] In some technical solutions, the scroll assembly may optionally include: an enthalpy-increasing valve seat connected to the stationary scroll, the enthalpy-increasing valve seat having a groove, the stationary scroll having an air inlet hole, and the air inlet hole being connected to the enthalpy-increasing air inlet group through the groove.

[0028] The enthalpy-increasing valve seat has grooves machined into it. When the enthalpy-increasing valve seat is installed on the stationary vortex plate, the grooves engage with the stationary vortex plate, thereby forming an enthalpy-increasing channel between the enthalpy-increasing valve seat and the stationary vortex plate.

[0029] An air inlet is provided on the stationary vortex disk, which is connected to the air intake channel. The groove is also connected to the air inlet, allowing gas in the air intake channel to be supplied into the groove through the air inlet. The enthalpy-enhancing air intake assembly is connected to the groove, so the gas supplied into the groove can flow into the first and second compression chambers through the enthalpy-enhancing air intake assembly.

[0030] By forming an enthalpy-increasing channel between the enthalpy-increasing valve seat and the stationary volute, the enthalpy-increasing channel is placed on the outer surface of the stationary volute, thus eliminating the need to machine the enthalpy-increasing channel on the stationary volute, which helps to reduce the machining difficulty of the stationary volute.

[0031] In some technical solutions, optionally, the enthalpy-increasing air intake group is located on the side of the groove extending in the direction of the groove, and the side of the groove extending in the direction of the groove is spaced apart from the air inlet hole. The stationary vortex disk is provided with an air intake channel, one end of the air inlet hole is connected to the groove, and the other end of the air inlet hole is connected to the air intake channel.

[0032] The air intake channel supplies air to the enthalpy-increasing air intake assembly through the air inlet and the groove. The air inlet and the groove are spaced apart on their sides in the extending direction. When the gas in the air inlet is supplied into the groove, the sides of the groove in the extending direction will not obstruct the supplied gas, thus ensuring the smooth flow of gas into the groove.

[0033] When the enthalpy-enhancing air intake group is set on the side of the groove extending direction, when the gas flows to the side of the groove extending direction, it is blocked by the inner wall of the groove side and the gas can only flow to the enthalpy-enhancing air intake group, thereby improving the air intake efficiency of the enthalpy-enhancing air intake group.

[0034] Secondly, this utility model proposes a scroll compressor, including the scroll assembly in any of the above technical solutions.

[0035] Thirdly, this utility model proposes an air conditioner, including the scroll compressor described in the second aspect.

Detailed Implementation

[0048] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0049] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0050] The following reference Figures 1 to 8 This invention describes a scroll assembly, a scroll compressor, and an air conditioner provided according to some embodiments of the present invention.

[0051] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments of this utility model, a scroll assembly 100 is proposed, including: a stationary scroll 110, a moving scroll 120, and an enthalpy-increasing intake assembly 150. The moving scroll 120 and the stationary scroll 110 enclose a plurality of compression chambers 170, the plurality of compression chambers 170 including a first compression chamber 130 and a second compression chamber 140. The moving scroll 120 includes moving scroll teeth 121, along the radial direction of the moving scroll 120 ( Figure 4(The arrow at point R points to) The first compression chamber 130 and the second compression chamber 140 are located on both sides of the moving volute 121. When the first compression chamber 130 is closed after intake, it faces the first region 111 on the stationary volute 110. When the second compression chamber 140 is closed after intake, it faces the second region 112 on the stationary volute 110. Figure 4 (The area enclosed by the dashed line). The enthalpy-increasing air intake group 150 is disposed on the stationary vortex disk 110. The enthalpy-increasing air intake group 150 is used to increase the enthalpy of the gas in the first compression chamber 130 and the second compression chamber 140. At least a portion of the enthalpy-increasing air intake group 150 is located in the first region 111 and the second region 112.

[0052] A first compression chamber 130 and a second compression chamber 140 are formed between the stationary volute 110 and the moving volute 120. Since the first compression chamber 130 and the second compression chamber 140 are located on both sides of the moving volute 121 along the radial direction of the moving volute 120, that is, the first compression chamber 130 is the outer compression chamber and the second compression chamber 140 is the inner compression chamber, or the first compression chamber 130 is the inner compression chamber and the second compression chamber 140 is the outer compression chamber.

[0053] One of the first compression chamber 130 and the second compression chamber 140 will draw in air first. In this embodiment, the first compression chamber 130 will draw in air first for illustrative purposes. When the first compression chamber 130 has finished drawing in air and just closed, the position of the first compression chamber 130 corresponds to the first region 111 on the stationary scroll plate 110. After the first compression chamber 130 closes after drawing in air, as the scroll compressor 200 continues to operate, the second compression chamber 140 will begin to draw in air. When the second compression chamber 140 has finished drawing in air and just closed, the position of the second compression chamber 140 corresponds to the second region 112 on the stationary scroll plate 110.

[0054] When the first compression chamber 130 has finished intake and just closed, the gas inside the first compression chamber 130 has not yet been compressed, or has just begun to be compressed, and the pressure inside the first compression chamber 130 is relatively low. Similarly, when the second compression chamber 140 has finished intake and just closed, the gas inside the second compression chamber 140 has not yet been compressed, or has just begun to be compressed, and the pressure inside the second compression chamber 140 is relatively low.

[0055] The enthalpy-enhancing intake assembly 150 can replenish gaseous refrigerant into the first compression chamber 130 and the second compression chamber 140. The gaseous refrigerant replenished into the first compression chamber 130 and the second compression chamber 140 merges with the gas being compressed. Compared with a compressor that does not perform jet enthalpy enhancement, the scroll compressor 200 in this scheme has a larger enthalpy difference on the evaporator side, which is beneficial to improving the heating capacity.

[0056] The enthalpy-increasing intake assembly 150 is disposed on the stationary scroll plate 110, and the enthalpy-increasing intake assembly 150 is located within the first region 111 and the second region 112. Therefore, the enthalpy-increasing intake assembly 150 corresponds to the position with lower pressure in the first compression chamber 130 and the second compression chamber 140. Under the condition of constant external intake pressure, the enthalpy-increasing intake assembly 150 can more easily increase the enthalpy of the gas supplied to the first compression chamber 130 and the second compression chamber 140, thereby increasing the amount of gas supplied to the first compression chamber 130 and the second compression chamber 140 per unit time. As the amount of gas supplied increases, the heating capacity of the scroll compressor 200 can be further improved, which is conducive to improving the heating capacity of the air conditioner per unit time.

[0057] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, a third region 113 is provided on the stationary vortex disk 110, the third region 113 being the overlapping region of the first region 111 and the second region 112, and at least a portion of the enthalpy-increasing intake group 150 is located in the third region 113.

[0058] The first region 111 and the second region 112 have overlapping areas, which are designated as the third region 113. The enthalpy-increasing air intake group 150 is located in the third region 113.

[0059] The space occupied by the first compression chamber 130 and the second compression chamber 140 when the air intake is completed overlaps with each other. This overlapping space corresponds to the third region 113. The aforementioned overlapping space has a large length or width, and the air intake resistance in this part of the space is small. Therefore, when the enthalpy-enhancing air intake group 150 is set in the third region 113, the enthalpy-enhancing air intake group 150 can more easily supplement the first compression chamber 130 and the second compression chamber 140 with enthalpy-enhancing air, increase the amount of air supplemented into the first compression chamber 130 and the second compression chamber 140 per unit time, and improve the unit's energy efficiency ratio while increasing the heating capacity, thereby improving the heating capacity.

[0060] In this embodiment, the enthalpy-increasing air intake group 150 can be an air intake port, which is located in the third region 113.

[0061] In this embodiment, at least a portion of the enthalpy-increasing air intake group 150 is disposed within the overlapping area of ​​the first region 111 and the second region 112. Of course, in other embodiments, a portion of the enthalpy-increasing air intake group 150 may be disposed within the first region 111, and another portion may be disposed within the second region 112. This can also increase the amount of air supplied to the compression chamber 170. That is, the two portions of the enthalpy-increasing air intake group 150 are respectively disposed at positions where the first region 111 and the second region 112 do not overlap.

[0062] In one possible embodiment, a portion of the enthalpy-increasing air intake group 150 is disposed in the third region 113, another portion of the enthalpy-increasing air intake group 150 is disposed in the first region 111 or the second region 112, and the other portion of the enthalpy-increasing air intake group 150 is disposed above the first region 111 or the second region 112 at a position where they do not overlap.

[0063] In one possible embodiment, a portion of the enthalpy-enhancing intake group 150 is disposed within the third region 113, while another portion of the enthalpy-enhancing intake group 150 is disposed outside the first region 111 and the second region 112.

[0064] Combination Figure 4 and Figure 5 As shown, in some embodiments, optionally, the maximum width of the third region 113 along the radial direction of the moving scroll 120 is W. Lines L1 and L2 are defined to extend radially along the moving scroll 120, with line L1 having a length of W within the third region 113 and line L2 having a length of 0.5W within the third region 113. The enthalpy-enhancing intake assembly 150 is located between line L1 and line L2.

[0065] Along the radial direction of the moving scroll 120, the wider the third region 113, the smaller the air intake resistance. Therefore, the position of the enthalpy-increasing air intake group 150 needs to be selected with reference to the width of the third region 113.

[0066] Both straight lines L1 and L2 extend radially along the moving scroll 120. A portion of straight line L1 lies within the third region 113, and the length of this portion of line L1 within the third region 113 is W. Since the maximum width of the third region 113 radially along the moving scroll 120 is also W, straight line L1 passes through the position with the maximum width within the third region 113. Similarly, a portion of straight line L2 lies within the third region 113, and the length of this portion of line L2 within the third region 113 is 0.5W. Therefore, straight line L2 passes through the position where the maximum width within the third region 113 is halfway down.

[0067] The enthalpy-enhancing air intake assembly 150 is positioned between straight lines L1 and L2, thus placing it within a wider area of ​​the third region 113. This area has lower air intake resistance, making it easier for the enthalpy-enhancing air intake assembly 150 to replenish the first compression chamber 130 and the second compression chamber 140 with enthalpy, thereby increasing the amount of air replenished to the first compression chamber 130 and the second compression chamber 140 per unit time.

[0068] like Figure 4 As shown, the lengths of both straight line L2 and dashed line L3 passing through the third region 113 are 0.5W. Therefore, the enthalpy-increasing intake group 150 can be set between straight line L1 and straight line L2, or between straight line L1 and dashed line L3.

[0069] Combination Figure 4 and Figure 5 As shown, in some embodiments, optionally, the enthalpy-increasing air intake assembly 150 includes: a first air intake 151 and a second air intake 152. The first air intake 151 is disposed on the first region 111 and is used to add enthalpy-increasing air to the first compression chamber 130. The second air intake 152 is disposed on the second region 112 and is used to add enthalpy-increasing air to the second compression chamber 140.

[0070] The first air inlet 151 can supply air to the first compression chamber 130, and the second air inlet 152 can supply air to the second compression chamber 140. Therefore, the first compression chamber 130 and the second compression chamber 140 can be supplied with air independently. For example, the first compression chamber 130 can be supplied with air first through the first air inlet 151, and then the second compression chamber 140 can be supplied with air through the second air inlet 152. Alternatively, the first air inlet 151 and the second air inlet 152 can supply air simultaneously.

[0071] With the gas replenishment structure provided in both the first compression chamber 130 and the second compression chamber 140, the first compression chamber 130 and the second compression chamber 140 can achieve different enthalpy increases. The enthalpy increase can be adjusted according to usage requirements, which is beneficial to improving the heating capacity of the air conditioner.

[0072] Combination Figure 5 and Figure 6 As shown, in some embodiments, optionally, the stationary vortex disk 110 is provided with an air intake channel 114, and the first air intake hole 151 and the second air intake hole 152 are both connected to the air intake channel 114.

[0073] An air intake channel 114 is machined on the stationary vortex disk 110. Since the first air intake hole 151 and the second air intake hole 152 are both connected to the air intake channel 114, the gas in the air intake channel 114 can be diverted to the first air intake hole 151 and the second air intake hole 152.

[0074] The jet enthalpy enhancement structure in this solution achieves dual-channel air replenishment by setting the first air inlet 151 and the second air inlet 152 as two independent jet structures. On this basis, the first air inlet 151 and the second air inlet 152 share a common air intake channel 114, which can achieve the function of simultaneous air replenishment. Compared with the method of sequentially replenishing different cavities with air inlets, the structure of the first air inlet 151 and the second air inlet 152 sharing a common air intake channel 114 in this solution can reduce the air replenishment frequency and improve the air replenishment efficiency.

[0075] like Figure 5 As shown, in some embodiments, optionally, the number of first air inlets 151 is at least two, and / or the number of second air inlets 152 is at least two.

[0076] The first air inlet 151 is used to replenish air into the first compression chamber 130. Due to the size limitation of the first compression chamber 130, the diameter of the first air inlet 151 will not be too large. Therefore, by increasing the number of first air inlets 151, rapid air replenishment to the first compression chamber 130 can be achieved.

[0077] Similarly, the second air inlet 152 is used to replenish air into the second compression chamber 140. Due to the size limitation of the second compression chamber 140, the diameter of the second air inlet 152 will not be too large. Therefore, by increasing the number of second air inlets 152, rapid air replenishment to the second compression chamber 140 can be achieved.

[0078] Combination Figure 5 and Figure 6 As shown, in some embodiments, optionally, the vortex assembly 100 further includes: an enthalpy-increasing valve seat 160, which is connected to the stationary vortex 110. The enthalpy-increasing valve seat 160 is provided with a groove 161, and the stationary vortex 110 is provided with an air supply hole 115. The air supply hole 115 is connected to the enthalpy-increasing air intake group 150 through the groove 161.

[0079] The enthalpy-increasing valve seat 160 has a groove 161 machined on it. When the enthalpy-increasing valve seat 160 is installed on the stationary vortex plate 110, the groove 161 engages with the stationary vortex plate 110, thereby forming an enthalpy-increasing channel between the enthalpy-increasing valve seat 160 and the stationary vortex plate 110.

[0080] A gas inlet hole 115 is provided on the stationary vortex disk 110, which is connected to the air intake channel 114. The groove 161 is connected to the gas inlet hole 115, and the gas in the air intake channel 114 is replenished into the groove 161 through the gas inlet hole 115. The enthalpy-increasing air intake assembly 150 is connected to the groove 161, so the gas replenished into the groove 161 can flow into the first compression chamber 130 and the second compression chamber 140 through the enthalpy-increasing air intake assembly 150.

[0081] By forming an enthalpy-increasing channel between the enthalpy-increasing valve seat 160 and the stationary vortex disk 110, the enthalpy-increasing channel is placed on the outer surface of the stationary vortex disk 110, thus eliminating the need to machine the enthalpy-increasing channel on the stationary vortex disk 110, which helps to reduce the machining difficulty of the stationary vortex disk 110.

[0082] For example, the enthalpy-increasing valve seat 160 is locked to the stationary scroll plate 110 by screws, or the enthalpy-increasing valve seat 160 is welded to the stationary scroll plate 110.

[0083] Combination Figure 5 and Figure 6 As shown, in some embodiments, optionally, the enthalpy-increasing air intake assembly 150 is located in the extending direction of the groove 161 ( Figure 5The side of the L-shaped groove 161 is spaced apart from the side of the air inlet hole 115 in the direction of extension. The static vortex disk 110 is provided with an air intake channel 114. One end of the air inlet hole 115 is connected to the groove 161, and the other end of the air inlet hole 115 is connected to the air intake channel 114.

[0084] The air intake channel 114 supplies air to the enthalpy-increasing air intake assembly 150 through the air supply hole 115 and the groove 161. The air supply hole 115 and the groove 161 are spaced apart in the extending direction. When the gas in the air supply hole 115 is supplied into the groove 161, the side of the groove 161 in the extending direction will not obstruct the supplied gas, thereby ensuring the smooth flow of gas into the groove 161.

[0085] When the enthalpy-enhancing air intake assembly 150 is located on the side of the groove 161 extending in the direction of extension, when the gas flows to the side of the groove 161 extending in the direction of extension, it is obstructed by the inner wall of the side of the groove 161, and the gas can only flow to the enthalpy-enhancing air intake assembly 150, thereby improving the air intake efficiency of the enthalpy-enhancing air intake assembly 150.

[0086] like Figure 8 As shown, in an embodiment of this utility model, a scroll compressor 200 is proposed, which includes the scroll assembly 100 in any of the above embodiments and can achieve the same technical effect, which will not be described again here.

[0087] In one possible application, the scroll compressor 200 also includes a cross-slip ring 210, a main frame 220, a crankshaft 230, and a motor 240. The enthalpy-increasing intake assembly 150 is located on the stationary scroll plate 110, and its function is to inject gaseous refrigerant into the scroll compression chamber. The liquid refrigerant at the condenser outlet, after its injection flow rate is regulated by an electronic expansion valve, undergoes heat exchange with the main refrigerant in the economizer to become superheated vapor, and is then injected into the intermediate-pressure chamber of the scroll compressor 200 via the injection circuit, merging with the gas being compressed in the compression chamber. Furthermore, the main liquid refrigerant is further subcooled in the economizer, resulting in a larger enthalpy difference on the evaporator side compared to a typical heat pump cycle without injection, thus increasing heating and cooling capacity.

[0088] In the embodiments of this utility model, an air conditioner is proposed, which includes the scroll compressor in the above embodiments and can achieve the same technical effect, and will not be described again here.
