[0003] Therefore, there is an urgent need for a new type of jet enthalpy-enhancing compressor that can simplify the structure, reduce the size, and improve energy efficiency while ensuring system performance, so as to adapt to a wider range of application scenarios. Utility Model Content

[0015] Thirdly, an electrical device is provided, including the refrigeration system as described above.

[0016] The application employs the above technical solution and has at least the following beneficial effects: This application provides a vapor injection enthalpy enhancement system, a refrigeration system, and electrical equipment. The vapor injection enthalpy enhancement system includes a compressor, a gas injection passage, and a refrigerant passage. A gas injection pipe is provided at the gas injection port of the compressor, and a micro-orifice plate throttling device is installed inside the gas injection pipe. One end of the gas injection passage is connected to the gas injection pipe, and the other end is connected to the condenser. One end of the refrigerant passage is connected to the throttling device, and the other end is connected to the condenser.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this utility model will be described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Traditional jet enthalpy enhancement systems, such as Figure 1 As shown, it includes: condenser 4, compressor 1, four-way valve 7, primary throttling device 9, secondary throttling device 11, flash evaporator 10 (such as a flash tank), and evaporator 8. It is understandable that... Figure 1 The structure shown is only an example; some existing systems do not use the four-way valve 7.

[0022] Its workflow is as follows: Compressor 1 draws in low-temperature, low-pressure refrigerant gas from evaporator 8, compresses it into high-temperature, high-pressure gas, and enters condenser 4. The high-pressure liquid condensed in condenser 4 is reduced in pressure and throttled by a first-stage throttling device 9, forming a medium-pressure gas-liquid mixture that enters flash evaporator 10. Flash evaporator 10 performs gas-liquid separation, and the separated gas enters the compression chamber of compressor 1 through the compressor 1's gas inlet to participate in compression. These gases are compressed again in compressor 1, increasing the total discharge capacity of compressor 1, improving the refrigerant circulation of the system, and thus increasing the system's heating / cooling capacity.

[0023] The liquid separated from the flash evaporator 10 enters the secondary throttling device 11, and after throttling, it enters the evaporator 8 to absorb heat from the air and complete the cycle.

[0024] Traditional enthalpy-increasing systems are prone to gas injection noise and stress concentration-induced pipe breakage during operation because the flash evaporator 10 is mounted on the system. In addition, the structure is complex and the cost is high. It should be noted that flash evaporation is when high-pressure saturated water enters a lower-pressure container, and due to the sudden drop in pressure, this saturated water is transformed into saturated water vapor and saturated water under the container's pressure.

[0025] Relationship between boiling point and pressure The boiling point of a substance increases with increasing pressure and decreases with decreasing pressure. Utilizing this property, the boiling point of a high-pressure, high-temperature fluid decreases after depressurization. When these fluids enter a flash tank, their temperature remains above their boiling point at that pressure. In the flash tank, the fluid rapidly boils and vaporizes, achieving vapor-liquid phase separation.

[0026] Taking a flash tank as an example, the working principle of flash evaporator 10 is explained as follows: Flash evaporators utilize the difference in saturated vapor pressure of substances at different temperatures to promote the rapid evaporation of liquids by reducing pressure, thereby achieving the conversion of liquid into gas.

[0027] Structure of flash tank A flash tank typically consists of a tank body, inlet pipe, outlet pipe, steam pipe, and vent pipe. The tank body is the core component of the flash tank and is usually made of stainless steel, offering excellent corrosion resistance, high-temperature resistance, and pressure resistance. The inlet and outlet pipes are responsible for inputting and outputting liquid into and out of the flash tank, respectively. The steam pipe is used to introduce steam into the tank, while the vent pipe is used to expel gases from the tank.

[0028] When a liquid substance is introduced into the flash tank, high-temperature, high-pressure steam is injected through the steam pipe, rapidly increasing the pressure inside the tank. As the pressure increases, the saturated vapor pressure of the liquid substance also rises accordingly. However, due to the low temperature of the liquid substance, its saturated vapor pressure remains at a low level. Once the pressure inside the pipe reaches a certain value, the saturated vapor pressure of the liquid substance will fall below the pressure inside the tank, thus triggering a rapid evaporation process that converts the liquid substance into a gaseous state.

[0029] The brilliance of flash evaporators lies in their ability to efficiently convert liquid substances into a gaseous state, thereby improving production efficiency. At the same time, they also offer advantages in energy conservation and environmental protection, achieving this conversion at relatively low temperatures, reducing energy consumption and environmental pollution.

[0030] Taking water as an example, under atmospheric pressure, the boiling point of water is 100°C. Above this temperature, water can only be converted into steam, and its temperature cannot be further increased. The heat energy absorbed in this process is called "sensible heat" or saturated water sensible heat. Under the same conditions, the heat energy required to convert saturated water into steam is called "latent heat." However, when water is heated in a pressurized environment, its boiling point exceeds 100°C, thus requiring more sensible heat to sustain the heating process.

[0031] As pressure increases, the boiling point of water also rises, and its heat content also increases. When pressure decreases, some sensible heat is released, and this energy is absorbed as latent heat, causing some water to "flash" into steam.

[0032] However, in actual use, flash evaporators are large in size, take up a lot of space, and are expensive. Another serious problem is their extremely high noise level, which severely impacts the user experience. To solve the above problems, refer to Figure 2 This utility model provides a jet enthalpy enhancement system, including: a compressor 1, a gas injection passage, and a refrigerant passage; The compressor 1 is provided with an air supply pipe 2 at the air supply port, and the air supply pipe 2 is provided with a micro-orifice plate throttling device 3. In one embodiment, such as Figure 4As shown, the gas supply pipe 2 is not specially designed. However, in actual use, the micro-orifice plate throttling device 3 may not be able to completely convert the high-pressure liquid condensed by the condenser 4 into medium-pressure gas, resulting in liquid entering the compression chamber of the compressor 1, causing liquid slugging and other phenomena, seriously affecting the reliable operation of the compressor 1. Therefore, when using... Figure 4 When using the gas supply pipe 2 as shown, it is necessary to control the amount of high-pressure liquid entering the gas supply pipe 2 so that the high-pressure liquid condensed by the condenser 4 can be completely converted into medium-pressure gas, preventing liquid from entering the compression chamber of the compressor 1. However, controlling the amount of high-pressure liquid entering the gas supply pipe 2 will inevitably result in a smaller gas supply, affecting the efficiency of the compressor 1.

[0033] Therefore, in another embodiment of this application, such as Figure 5 As shown, the gas supply pipe 2 is provided with a liquid storage bend 12; The lowest point of the liquid storage bend 12 is at a lower horizontal height than the connection point between the gas supply pipe 2 and the compressor 1. Because the lowest point of the liquid storage bend 12 is at a lower horizontal height than the connection point between the gas supply pipe 2 and the compressor 1, any refrigerant that has not been converted into gas will remain in the liquid storage bend 12 and will not enter the gas supply pipe 2.

[0034] It is understandable that the liquid refrigerant in the liquid storage bend 12 can be cleaned periodically, or a drain outlet can be provided in the liquid storage bend 12 for direct discharge (in this case, it is necessary to prevent the refrigerant from entering the gas supply pipe 2, i.e., control the gas supply channel to be closed).

[0035] In one embodiment, the air supply pipe 2 contains only one microporous plate throttling device 3.

[0036] In another embodiment, the air supply pipe 2 is provided with a plurality of microporous plate throttling devices 3; The distance between any two of the microporous plate throttling devices 3 is not zero.

[0037] Multiple micro-orifice plate throttling devices 3 can ensure that the high-pressure liquid condensed by the condenser 4 is converted into medium-pressure gas. Furthermore, it can reduce the pressure reduction requirement of each micro-orifice plate throttling device 3. That is, when it is necessary to reduce the pressure of the high-pressure liquid at pressure A to B, the pressure reduction requirement for using one micro-orifice plate throttling device 3 is (AB). However, if n1 micro-orifice plate throttling devices 3 are set, the pressure reduction requirement for each micro-orifice plate throttling device 3 is (AB) / n1. Of course, due to the length limitation of the gas supply pipe 2, its number is limited; therefore, the specific number should be set according to the actual situation.

[0038] As a preferred implementation of the embodiments of this application, such as Figure 6 As shown, the microporous plate throttling device 3 is provided with multiple throttling holes.

[0039] Preferably, the microporous plate throttling device 3 is provided with n throttling orifices, where n is a positive integer greater than or equal to 60.

[0040] In addition, the diameter of each of the throttling orifices is 0.3-0.5 mm.

[0041] It should be noted that the micro-orifice throttling device 6 reduces the flow cross-section, causing the fluid velocity to increase and the static pressure to decrease as it passes through, thus achieving pressure reduction. Before entering the micro-orifice, the fluid has a higher pressure and a lower velocity. As it passes through the micro-orifice, the cross-sectional area decreases sharply, the velocity rises rapidly, and the static pressure drops. After exiting the micro-orifice, the velocity gradually decreases, but the pressure is already lower than the inlet pressure, completing the pressure reduction. After throttling, the refrigerant temperature is higher than the saturation temperature under the new pressure, and the system will spontaneously vaporize to restore equilibrium.

[0042] One end of the gas supply passage is connected to the gas supply pipe 2, and the other end is connected to the condenser 4; One end of the refrigerant passage is connected to the throttling device 6, and the other end is connected to the condenser 4.

[0043] As a preferred implementation of this application, a three-way valve 5 is also included; The inlet of the three-way valve 5 is connected to the condenser 4; The first outlet of the three-way valve 5 is connected to the refrigerant passage; The second outlet of the three-way valve 5 is connected to the air supply passage.

[0044] The three-way valve 5 has a flow regulation function.

[0045] The workflow of this application embodiment is as follows: Compressor 1 draws in low-temperature, low-pressure refrigerant gas from evaporator 8, compresses it into high-temperature, high-pressure gas, and enters condenser 4. The high-pressure liquid condensed in condenser 4 enters three-way valve 5. Part of the liquid enters the orifice plate throttling device 3 at the compressor 1 end, where it is depressurized and throttled, transforming into medium-pressure gaseous refrigerant. This gas then enters the compression chamber of compressor 1 to participate in compression. This further compression within compressor 1 increases the total discharge capacity of compressor 1, improves the refrigerant circulation rate of the system, and thus enhances the system's heating / cooling capacity. The remaining liquid enters the system throttling device 6, and after throttling, enters evaporator 8 to absorb heat from the air, completing the cycle.

[0046] It should be noted that, Figure 2 The system shown is a system using the four-way valve 7, but in practice, it can also be applied to systems that do not use the four-way valve 7.

[0047] The flow rate to the compressor 1 air inlet micro-orifice plate throttling device 3 is V1, and the flow rate to the system throttling valve entering the evaporator 8 is V2. Preferably, 0.05≤V1 / V2≤0.1, the air conditioning system has the best energy efficiency.

[0048] The vapor injection enthalpy enhancement system provided in this application includes a compressor, a gas injection passage, and a refrigerant passage. A gas injection pipe is provided at the gas injection port of the compressor, and a microporous plate throttling device is installed inside the gas injection pipe. One end of the gas injection passage is connected to the gas injection pipe, and the other end is connected to the condenser. One end of the refrigerant passage is connected to the throttling device, and the other end is connected to the condenser. In this application, a portion of the high-pressure liquid refrigerant condensed by the condenser enters the gas injection pipe through the gas injection passage. The microporous plate throttling device inside the gas injection pipe converts the high-pressure liquid refrigerant into medium-pressure gas, which then enters the compressor to supply gas. The other portion of the high-pressure liquid refrigerant condensed by the condenser passes through the refrigerant passage and the throttling device, returning to the evaporator to complete the cycle. Because the gas injection is depressurized and vaporized through the microporous plate throttling device inside the gas injection pipe, a flash evaporator is not required, resulting in a small footprint and low noise, greatly improving the user experience.

[0049] like Figure 3 As shown, this application embodiment also provides a jet enthalpy enhancement system, including: a compressor 1, a gas injection passage, and a refrigerant passage; The compressor 1 is provided with an air supply pipe 2 at the air supply port, and the air supply pipe 2 is provided with a micro-orifice plate throttling device 3. In one embodiment, such as Figure 4 As shown, the gas supply pipe 2 is not specially designed. However, in actual use, the micro-orifice plate throttling device 3 may not be able to completely convert the high-pressure liquid condensed by the condenser 4 into medium-pressure gas, resulting in liquid entering the compression chamber of the compressor 1, causing liquid slugging and other phenomena, seriously affecting the reliable operation of the compressor 1. Therefore, when using... Figure 4 When using the gas supply pipe 2 as shown, it is necessary to control the amount of high-pressure liquid entering the gas supply pipe 2 so that the high-pressure liquid condensed by the condenser 4 can be completely converted into medium-pressure gas, preventing liquid from entering the compression chamber of the compressor 1. However, controlling the amount of high-pressure liquid entering the gas supply pipe 2 will inevitably result in a smaller gas supply, affecting the efficiency of the compressor 1.

[0050] Therefore, in another embodiment of this application, such as Figure 5 As shown, the gas supply pipe 2 is provided with a liquid storage bend 12; The lowest point of the liquid storage bend 12 is at a lower horizontal height than the connection point between the gas supply pipe 2 and the compressor 1. Because the lowest point of the liquid storage bend 12 is at a lower horizontal height than the connection point between the gas supply pipe 2 and the compressor 1, any refrigerant that has not been converted into gas will remain in the liquid storage bend 12 and will not enter the gas supply pipe 2.

[0051] It is understandable that the liquid refrigerant in the liquid storage bend 12 can be cleaned periodically, or a drain outlet can be provided in the liquid storage bend 12 for direct discharge (in this case, it is necessary to prevent the refrigerant from entering the gas supply pipe 2, i.e., control the gas supply channel to be closed).

[0052] In one embodiment, the air supply pipe 2 contains only one microporous plate throttling device 3.

[0053] In another embodiment, the air supply pipe 2 is provided with a plurality of microporous plate throttling devices 3; The distance between any two of the microporous plate throttling devices 3 is not zero.

[0054] Multiple micro-orifice plate throttling devices 3 can ensure that the high-pressure liquid condensed by the condenser 4 is converted into medium-pressure gas. Furthermore, it can reduce the pressure reduction requirement of each micro-orifice plate throttling device 3. That is, when it is necessary to reduce the pressure of the high-pressure liquid at pressure A to B, the pressure reduction requirement for using one micro-orifice plate throttling device 3 is (AB). However, if n1 micro-orifice plate throttling devices 3 are set, the pressure reduction requirement for each micro-orifice plate throttling device 3 is (AB) / n1. Of course, due to the length limitation of the gas supply pipe 2, its number is limited; therefore, the specific number should be set according to the actual situation.

[0055] As a preferred implementation of the embodiments of this application, such as Figure 6 As shown, the microporous plate throttling device 3 is provided with multiple throttling holes.

[0056] Preferably, the microporous plate throttling device 3 is provided with n throttling orifices, where n is a positive integer greater than or equal to 60.

[0057] In addition, the diameter of each of the throttling orifices is 0.3-0.5 mm.

[0058] It should be noted that the micro-orifice throttling device 6 reduces the flow cross-section, causing the fluid velocity to increase and the static pressure to decrease as it passes through, thus achieving pressure reduction. Before entering the micro-orifice, the fluid has a higher pressure and a lower velocity. As it passes through the micro-orifice, the cross-sectional area decreases sharply, the velocity rises rapidly, and the static pressure drops. After exiting the micro-orifice, the velocity gradually decreases, but the pressure is already lower than the inlet pressure, completing the pressure reduction. After throttling, the refrigerant temperature is higher than the saturation temperature under the new pressure, and the system will spontaneously vaporize to restore equilibrium.

[0059] One end of the gas supply passage is connected to the gas supply pipe 2, and the other end is connected to the condenser 4; One end of the refrigerant passage is connected to the throttling device 6, and the other end is connected to the condenser 4.

[0060] As a preferred implementation of the present application, it further includes a first solenoid valve 13 and a second solenoid valve 14; The first solenoid valve 13 is disposed in the refrigerant passage; The second solenoid valve 14 is disposed in the air supply passage.

[0061] That is, the refrigerant passage and the gas supply passage are independent of each other and do not affect each other. Their respective flow rates are determined by the first solenoid valve and the second solenoid valve 14.

[0062] The workflow of this application embodiment is as follows: Compressor 1 draws in low-temperature, low-pressure refrigerant gas from evaporator 8, compresses it into high-temperature, high-pressure gas, and enters condenser 4. A portion of the high-pressure liquid condensed in condenser 4 passes through the second solenoid valve 14 into the orifice plate throttling device 3 at the compressor 1 end. The orifice plate throttling device 3 reduces the pressure and converts the liquid into medium-pressure gaseous refrigerant, which then enters the compression chamber of compressor 1 to participate in compression. This gas is further compressed in compressor 1, increasing the total discharge capacity of compressor 1 and improving the refrigerant circulation rate of the system, thereby enhancing the system's heating / cooling capacity. The remaining liquid passes through the first solenoid valve 13 into the system throttling device 6, and after throttling, enters evaporator 8 to absorb heat from the air, completing the cycle.

[0063] It should be noted that, Figure 3 The system shown is a system using the four-way valve 7, but in practice, it can also be applied to systems that do not use the four-way valve 7.

[0064] The vapor injection enthalpy enhancement system provided in this application includes a compressor, a gas injection passage, and a refrigerant passage. A gas injection pipe is provided at the gas injection port of the compressor, and a microporous plate throttling device is installed inside the gas injection pipe. One end of the gas injection passage is connected to the gas injection pipe, and the other end is connected to the condenser. One end of the refrigerant passage is connected to the throttling device, and the other end is connected to the condenser. In this application, a portion of the high-pressure liquid refrigerant condensed by the condenser enters the gas injection pipe through the gas injection passage. The microporous plate throttling device inside the gas injection pipe converts the high-pressure liquid refrigerant into medium-pressure gas, which then enters the compressor to supply gas. The other portion of the high-pressure liquid refrigerant condensed by the condenser passes through the refrigerant passage and the throttling device, returning to the evaporator to complete the cycle. Because the gas injection is depressurized and vaporized through the microporous plate throttling device inside the gas injection pipe, a flash evaporator is not required, resulting in a small footprint and low noise, greatly improving the user experience.

[0065] Based on the same inventive concept, this application also provides a refrigeration system that utilizes the following vapor injection enthalpy enhancement system, such as... Figure 2 As shown, it includes: Compressor 1, gas supply passage and refrigerant passage; The compressor 1 is provided with an air supply pipe 2 at the air supply port, and the air supply pipe 2 is provided with a micro-orifice plate throttling device 3. In one embodiment, such as Figure 4As shown, the gas supply pipe 2 is not specially designed. However, in actual use, the micro-orifice plate throttling device 3 may not be able to completely convert the high-pressure liquid condensed by the condenser 4 into medium-pressure gas, resulting in liquid entering the compression chamber of the compressor 1, causing liquid slugging and other phenomena, seriously affecting the reliable operation of the compressor 1.

Figure 4 When using the gas supply pipe 2 as shown, it is necessary to control the amount of high-pressure liquid entering the gas supply pipe 2 so that the high-pressure liquid condensed by the condenser 4 can be completely converted into medium-pressure gas, preventing liquid from entering the compression chamber of the compressor 1. However, controlling the amount of high-pressure liquid entering the gas supply pipe 2 will inevitably result in a smaller gas supply, affecting the efficiency of the compressor 1.

[0066] Therefore, in another embodiment of this application, such as Figure 5 As shown, the gas supply pipe 2 is provided with a liquid storage bend 12; The lowest point of the liquid storage bend 12 is at a lower horizontal height than the connection point between the gas supply pipe 2 and the compressor 1. Because the lowest point of the liquid storage bend 12 is at a lower horizontal height than the connection point between the gas supply pipe 2 and the compressor 1, any refrigerant that has not been converted into gas will remain in the liquid storage bend 12 and will not enter the gas supply pipe 2.

[0067] It is understandable that the liquid refrigerant in the liquid storage bend 12 can be cleaned periodically, or a drain outlet can be provided in the liquid storage bend 12 for direct discharge (in this case, it is necessary to prevent the refrigerant from entering the gas supply pipe 2, i.e., control the gas supply channel to be closed).

[0068] In one embodiment, the air supply pipe 2 contains only one microporous plate throttling device 3.

[0069] In another embodiment, the air supply pipe 2 is provided with a plurality of microporous plate throttling devices 3; The distance between any two of the microporous plate throttling devices 3 is not zero.

[0070] Multiple micro-orifice plate throttling devices 3 can ensure that the high-pressure liquid condensed by the condenser 4 is converted into medium-pressure gas. Furthermore, it can reduce the pressure reduction requirement of each micro-orifice plate throttling device 3. That is, when it is necessary to reduce the pressure of the high-pressure liquid at pressure A to B, the pressure reduction requirement for using one micro-orifice plate throttling device 3 is (AB). However, if n1 micro-orifice plate throttling devices 3 are set, the pressure reduction requirement for each micro-orifice plate throttling device 3 is (AB) / n1. Of course, due to the length limitation of the gas supply pipe 2, its number is limited; therefore, the specific number should be set according to the actual situation.

[0071] As a preferred implementation of the embodiments of this application, such as Figure 6 As shown, the microporous plate throttling device 3 is provided with multiple throttling holes.

[0072] Preferably, the microporous plate throttling device 3 is provided with n throttling orifices, where n is a positive integer greater than or equal to 60.

[0073] In addition, the diameter of each of the throttling orifices is 0.3-0.5 mm.

[0074] It should be noted that the micro-orifice throttling device 6 reduces the flow cross-section, causing the fluid velocity to increase and the static pressure to decrease as it passes through, thus achieving pressure reduction.

[0075] One end of the gas supply passage is connected to the gas supply pipe 2, and the other end is connected to the condenser 4; One end of the refrigerant passage is connected to the throttling device 6, and the other end is connected to the condenser 4.

[0076] As a preferred implementation of the embodiments of this application, such as Figure 2 As shown, it also includes a three-way valve 5; The inlet of the three-way valve 5 is connected to the condenser 4; The first outlet of the three-way valve 5 is connected to the refrigerant passage; The second outlet of the three-way valve 5 is connected to the air supply passage.

[0077] The three-way valve 5 has a flow regulation function.

[0078] Figure 2 The working process of the jet antagonistic enhancement system shown is as follows: Compressor 1 draws in low-temperature, low-pressure refrigerant gas from evaporator 8, compresses it into high-temperature, high-pressure gas, and enters condenser 4. The high-pressure liquid condensed in condenser 4 enters three-way valve 5. Part of the liquid enters the orifice plate throttling device 3 at the compressor 1 end, where it is depressurized and throttled, transforming into medium-pressure gaseous refrigerant. This gas then enters the compression chamber of compressor 1 to participate in compression. This further compression within compressor 1 increases the total discharge capacity of compressor 1, improves the refrigerant circulation rate of the system, and thus enhances the system's heating / cooling capacity. The remaining liquid enters the system throttling device 6, and after throttling, enters evaporator 8 to absorb heat from the air, completing the cycle.

[0079] It should be noted that, Figure 2 The system shown is a system using the four-way valve 7, but in practice, it can also be applied to systems that do not use the four-way valve 7.

[0080] The flow rate to the compressor 1 air inlet micro-orifice plate throttling device 3 is V1, and the flow rate to the system throttling valve entering the evaporator 8 is V2. Preferably, 0.05≤V1 / V2≤0.1, the air conditioning system has the best energy efficiency.

[0081] Or, a jet ergonomic enhancement system such as Figure 3 As shown, it includes: compressor 1, gas injection passage and refrigerant passage; The compressor 1 is provided with an air supply pipe 2 at the air supply port, and the air supply pipe 2 is provided with a micro-orifice plate throttling device 3. In one embodiment, such as Figure 4 As shown, the gas supply pipe 2 is not specially designed. However, in actual use, the micro-orifice plate throttling device 3 may not be able to completely convert the high-pressure liquid condensed by the condenser 4 into medium-pressure gas, resulting in liquid entering the compression chamber of the compressor 1, causing liquid slugging and other phenomena, seriously affecting the reliable operation of the compressor 1. Therefore, when using... Figure 4 When using the gas supply pipe 2 as shown, it is necessary to control the amount of high-pressure liquid entering the gas supply pipe 2 so that the high-pressure liquid condensed by the condenser 4 can be completely converted into medium-pressure gas, preventing liquid from entering the compression chamber of the compressor 1. However, controlling the amount of high-pressure liquid entering the gas supply pipe 2 will inevitably result in a smaller gas supply, affecting the efficiency of the compressor 1.

[0082] Therefore, in another embodiment of this application, such as Figure 5 As shown, the gas supply pipe 2 is provided with a liquid storage bend 12; The lowest point of the liquid storage bend 12 is at a lower horizontal height than the connection point between the gas supply pipe 2 and the compressor 1. Because the lowest point of the liquid storage bend 12 is at a lower horizontal height than the connection point between the gas supply pipe 2 and the compressor 1, any refrigerant that has not been converted into gas will remain in the liquid storage bend 12 and will not enter the gas supply pipe 2.

[0083] It is understandable that the liquid refrigerant in the liquid storage bend 12 can be cleaned periodically, or a drain outlet can be provided in the liquid storage bend 12 for direct discharge (in this case, it is necessary to prevent the refrigerant from entering the gas supply pipe 2, i.e., control the gas supply channel to be closed).

[0084] In one embodiment, the air supply pipe 2 contains only one microporous plate throttling device 3.

[0085] In another embodiment, the air supply pipe 2 is provided with a plurality of microporous plate throttling devices 3; The distance between any two of the microporous plate throttling devices 3 is not zero.

[0086] Multiple micro-orifice plate throttling devices 3 can ensure that the high-pressure liquid condensed by the condenser 4 is converted into medium-pressure gas. Furthermore, it can reduce the pressure reduction requirement of each micro-orifice plate throttling device 3. That is, when it is necessary to reduce the pressure of the high-pressure liquid at pressure A to B, the pressure reduction requirement for using one micro-orifice plate throttling device 3 is (AB). However, if n1 micro-orifice plate throttling devices 3 are set, the pressure reduction requirement for each micro-orifice plate throttling device 3 is (AB) / n1. Of course, due to the length limitation of the gas supply pipe 2, its number is limited; therefore, the specific number should be set according to the actual situation.

[0087] As a preferred implementation of the embodiments of this application, such as Figure 6 As shown, the microporous plate throttling device 3 is provided with multiple throttling holes.

[0088] Preferably, the microporous plate throttling device 3 is provided with n throttling orifices, where n is a positive integer greater than or equal to 60.

[0089] In addition, the diameter of each of the throttling orifices is 0.3-0.5 mm.

[0090] It should be noted that the micro-orifice throttling device 6 reduces the flow cross-section, causing the fluid velocity to increase and the static pressure to decrease as it passes through, thus achieving pressure reduction. Before entering the micro-orifice, the fluid has a higher pressure and a lower velocity. As it passes through the micro-orifice, the cross-sectional area decreases sharply, the velocity rises rapidly, and the static pressure drops. After exiting the micro-orifice, the velocity gradually decreases, but the pressure is already lower than the inlet pressure, completing the pressure reduction. After throttling, the refrigerant temperature is higher than the saturation temperature under the new pressure, and the system will spontaneously vaporize to restore equilibrium.

[0091] One end of the gas supply passage is connected to the gas supply pipe 2, and the other end is connected to the condenser 4; One end of the refrigerant passage is connected to the throttling device 6, and the other end is connected to the condenser 4.

[0092] As a preferred implementation of the present application, it further includes a first solenoid valve 13 and a second solenoid valve 14; The first solenoid valve 13 is disposed in the refrigerant passage; The second solenoid valve 14 is disposed in the air supply passage.

[0093] That is, the refrigerant passage and the gas supply passage are independent of each other and do not affect each other. Their respective flow rates are determined by the first solenoid valve and the second solenoid valve 14.

[0094] Figure 3 The working process of the jet antagonistic enhancement system shown is as follows: Compressor 1 draws in low-temperature, low-pressure refrigerant gas from evaporator 8, compresses it into high-temperature, high-pressure gas, and enters condenser 4. A portion of the high-pressure liquid condensed in condenser 4 passes through the second solenoid valve 14 into the orifice plate throttling device 3 at the compressor 1 end. The orifice plate throttling device 3 reduces the pressure and converts the liquid into medium-pressure gaseous refrigerant, which then enters the compression chamber of compressor 1 to participate in compression. This gas is further compressed in compressor 1, increasing the total discharge capacity of compressor 1 and improving the refrigerant circulation rate of the system, thereby enhancing the system's heating / cooling capacity. The remaining liquid passes through the first solenoid valve 13 into the system throttling device 6, and after throttling, enters evaporator 8 to absorb heat from the air, completing the cycle.

[0095] It should be noted that, Figure 3 The system shown is a system using the four-way valve 7, but in practice, it can also be applied to systems that do not use the four-way valve 7.

[0096] The refrigeration system provided in this application embodiment utilizes a vapor injection antagonistic system, which includes a compressor, a gas injection passage, and a refrigerant passage. A gas injection pipe is provided at the gas injection port of the compressor, and a micro-orifice plate throttling device is installed inside the gas injection pipe. One end of the gas injection passage is connected to the gas injection pipe, and the other end is connected to the condenser. One end of the refrigerant passage is connected to the throttling device, and the other end is connected to the condenser. In this application, a portion of the high-pressure liquid refrigerant after condensation by the condenser enters the gas injection pipe through the gas injection passage. The micro-orifice plate throttling device inside the gas injection pipe converts the high-pressure liquid refrigerant into medium-pressure gas, which then enters the compressor to supply gas to it. The other portion of the high-pressure liquid refrigerant after condensation by the condenser passes through the refrigerant passage and the throttling device, returning to the evaporator to complete the cycle. Because the gas injection is depressurized and vaporized through the micro-orifice plate throttling device inside the gas injection pipe, a flash evaporator is not required, resulting in a smaller footprint and lower noise, significantly improving the user experience.

[0097] Based on the same inventive concept, embodiments of this application provide an electrical appliance, such as an air conditioner or a refrigerator. This electrical appliance includes a refrigeration system, wherein the refrigeration system includes a jet antagonistic system as follows. Figure 2 As shown, it includes: Compressor 1, gas supply passage and refrigerant passage; The compressor 1 is provided with an air supply pipe 2 at the air supply port, and the air supply pipe 2 is provided with a micro-orifice plate throttling device 3. In one embodiment, such as Figure 4 As shown, the gas supply pipe 2 is not specially designed. However, in actual use, the micro-orifice plate throttling device 3 may not be able to completely convert the high-pressure liquid condensed by the condenser 4 into medium-pressure gas, resulting in liquid entering the compression chamber of the compressor 1, causing liquid slugging and other phenomena, seriously affecting the reliable operation of the compressor 1. Therefore, when using... Figure 4When using the gas supply pipe 2 as shown, it is necessary to control the amount of high-pressure liquid entering the gas supply pipe 2 so that the high-pressure liquid condensed by the condenser 4 can be completely converted into medium-pressure gas, preventing liquid from entering the compression chamber of the compressor 1. However, controlling the amount of high-pressure liquid entering the gas supply pipe 2 will inevitably result in a smaller gas supply, affecting the efficiency of the compressor 1.

[0098] Therefore, in another embodiment of this application, such as Figure 5 As shown, the gas supply pipe 2 is provided with a liquid storage bend 12; The lowest point of the liquid storage bend 12 is at a lower horizontal height than the connection point between the gas supply pipe 2 and the compressor 1. Because the lowest point of the liquid storage bend 12 is at a lower horizontal height than the connection point between the gas supply pipe 2 and the compressor 1, any refrigerant that has not been converted into gas will remain in the liquid storage bend 12 and will not enter the gas supply pipe 2.

[0099] It is understandable that the liquid refrigerant in the liquid storage bend 12 can be cleaned periodically, or a drain outlet can be provided in the liquid storage bend 12 for direct discharge (in this case, it is necessary to prevent the refrigerant from entering the gas supply pipe 2, i.e., control the gas supply channel to be closed).

[0100] In one embodiment, the air supply pipe 2 contains only one microporous plate throttling device 3.

[0101] In another embodiment, the air supply pipe 2 is provided with a plurality of microporous plate throttling devices 3; The distance between any two of the microporous plate throttling devices 3 is not zero.

[0102] Multiple micro-orifice plate throttling devices 3 can ensure that the high-pressure liquid condensed by the condenser 4 is converted into medium-pressure gas. Furthermore, it can reduce the pressure reduction requirement of each micro-orifice plate throttling device 3. That is, when it is necessary to reduce the pressure of the high-pressure liquid at pressure A to B, the pressure reduction requirement for using one micro-orifice plate throttling device 3 is (AB). However, if n1 micro-orifice plate throttling devices 3 are set, the pressure reduction requirement for each micro-orifice plate throttling device 3 is (AB) / n1. Of course, due to the length limitation of the gas supply pipe 2, its number is limited; therefore, the specific number should be set according to the actual situation.

[0103] As a preferred implementation of the embodiments of this application, such as Figure 6 As shown, the microporous plate throttling device 3 is provided with multiple throttling holes.

[0104] Preferably, the microporous plate throttling device 3 is provided with n throttling orifices, where n is a positive integer greater than or equal to 60.

[0105] In addition, the diameter of each of the throttling orifices is 0.3-0.5 mm.

[0106] It should be noted that the micro-orifice throttling device 6 reduces the flow cross-section, causing the fluid velocity to increase and the static pressure to decrease as it passes through, thus achieving pressure reduction. Before entering the micro-orifice, the fluid has a higher pressure and a lower velocity. As it passes through the micro-orifice, the cross-sectional area decreases sharply, the velocity rises rapidly, and the static pressure drops. After exiting the micro-orifice, the velocity gradually decreases, but the pressure is already lower than the inlet pressure, completing the pressure reduction. After throttling, the refrigerant temperature is higher than the saturation temperature under the new pressure, and the system will spontaneously vaporize to restore equilibrium.

[0107] One end of the gas supply passage is connected to the gas supply pipe 2, and the other end is connected to the condenser 4; One end of the refrigerant passage is connected to the throttling device 6, and the other end is connected to the condenser 4.

[0108] As a preferred implementation of the embodiments of this application, such as Figure 2 As shown, it also includes a three-way valve 5; The inlet of the three-way valve 5 is connected to the condenser 4; The first outlet of the three-way valve 5 is connected to the refrigerant passage; The second outlet of the three-way valve 5 is connected to the air supply passage.

[0109] The three-way valve 5 has a flow regulation function.

[0110] Figure 2 The working process of the jet antagonistic enhancement system shown is as follows: Compressor 1 draws in low-temperature, low-pressure refrigerant gas from evaporator 8, compresses it into high-temperature, high-pressure gas, and enters condenser 4. The high-pressure liquid condensed in condenser 4 enters three-way valve 5. Part of the liquid enters the orifice plate throttling device 3 at the compressor 1 end, where it is depressurized and throttled, transforming into medium-pressure gaseous refrigerant. This gas then enters the compression chamber of compressor 1 to participate in compression.

The remaining liquid enters the system throttling device 6, and after throttling, enters evaporator 8 to absorb heat from the air, completing the cycle.

[0111] It should be noted that, Figure 2 The system shown is a system using the four-way valve 7, but in practice, it can also be applied to systems that do not use the four-way valve 7.

[0112] The flow rate to the compressor 1 air inlet micro-orifice plate throttling device 3 is V1, and the flow rate to the system throttling valve entering the evaporator 8 is V2. Preferably, 0.05≤V1 / V2≤0.1, the air conditioning system has the best energy efficiency.

[0113] Or, a jet ergonomic enhancement system such as Figure 3 As shown, it includes: compressor 1, gas injection passage and refrigerant passage; The compressor 1 is provided with an air supply pipe 2 at the air supply port, and the air supply pipe 2 is provided with a micro-orifice plate throttling device 3. In one embodiment, such as Figure 4 As shown, the gas supply pipe 2 is not specially designed. However, in actual use, the micro-orifice plate throttling device 3 may not be able to completely convert the high-pressure liquid condensed by the condenser 4 into medium-pressure gas, resulting in liquid entering the compression chamber of the compressor 1, causing liquid slugging and other phenomena, seriously affecting the reliable operation of the compressor 1.

However, controlling the amount of high-pressure liquid entering the gas supply pipe 2 will inevitably result in a smaller gas supply, affecting the efficiency of the compressor 1.

[0114] Therefore, in another embodiment of this application, such as Figure 5 As shown, the gas supply pipe 2 is provided with a liquid storage bend 12; The lowest point of the liquid storage bend 12 is at a lower horizontal height than the connection point between the gas supply pipe 2 and the compressor 1. Because the lowest point of the liquid storage bend 12 is at a lower horizontal height than the connection point between the gas supply pipe 2 and the compressor 1, any refrigerant that has not been converted into gas will remain in the liquid storage bend 12 and will not enter the gas supply pipe 2.

[0121] In addition, the diameter of each of the throttling orifices is 0.3-0.5 mm.
