Description

Technical Field

[0001] The invention belongs to the field of energy-saving air conditioners, and in particular to a refrigerant flow control system. Background Art

[0002] Refrigerant plays a vital role in the air-conditioning system. It is a special chemical substance that can absorb and release heat in the air-conditioning circulation system, thereby achieving indoor temperature regulation. When the refrigerant circulates inside the air-conditioner, it is first compressed into a high-temperature and high-pressure gas by the compressor, and then enters the condenser, where the refrigerant releases heat and condenses into a liquid. Next, the liquid refrigerant is reduced in pressure and temperature through the expansion valve, becoming a low-temperature and low-pressure liquid and entering the evaporator. In the evaporator, the refrigerant absorbs heat from the surrounding air, thereby lowering the air temperature and evaporating into a gas. Finally, this low-temperature and low-pressure gas refrigerant is sucked into the compressor again to start the next cycle. Through this cycle, the refrigerant continuously works inside the air-conditioner, so that the indoor environment is cooled and dehumidified, providing people with a comfortable living and working space.

[0003] However, the above technology often has the following defects: in the current air-conditioning refrigeration process, the indoor temperature tends to gradually decrease. Once the indoor temperature reaches the preset standard, there is no need to continue cooling down. If the flow rate of the refrigerant is still maintained at a normal level, it will cause excessive use. This phenomenon will inevitably lead to unnecessary waste of energy.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] Embodiment 1: Figures 1 to 6 As shown, a refrigerant flow control system according to an embodiment of the present invention comprises a controller 7, a compressor 1 and a condenser 3; the compressor 1 is connected to a flow sensor 2 through a pipeline, and the flow sensor 2 is used to monitor the flow of the refrigerant flowing through;

[0029] The condenser 3 is provided with a condensation tube 8, the inlet and outlet ends of the condensation tube 8 are both connected to a hollow block 9, the side wall of the hollow block 9 is connected to a connecting pipe 10, and the flow sensor 2 is connected to the connecting pipe 10 through a pipeline;

[0030] The connecting pipe 10 at the outlet end of the condenser 8 is connected to an expansion valve 4, and the expansion valve 4 can reduce the pressure and temperature of the high-temperature and high-pressure liquid refrigerant to turn it into a low-temperature and low-pressure liquid. The expansion valve 4 is connected to an evaporator 5 through a pipeline, and the evaporator 5 is connected to the compressor 1 through a pipeline;

[0031] The evaporator 5 is provided with a temperature sensor 6, and the temperature sensor 6 is used to measure the room temperature. The air inlet of the evaporator 5 is provided with a first temperature sensor, and the air outlet of the evaporator 5 is provided with a second temperature sensor. The controller 7 is used to receive data from the flow sensor 2, the temperature sensor 6, the first temperature sensor and the second temperature sensor;

[0032] When the air conditioner is started, the compressor 1 compresses the refrigerant to increase its pressure and temperature. Then the gaseous refrigerant passes through the pipeline through the flow sensor 2. The flow sensor 2 monitors the flow through the refrigerant pipeline in real time and feeds back the flow data to the controller 7. The controller 7 can control the flow of the refrigerant of the expansion valve 4 through the data to ensure that the flow always meets the system requirements. After passing through the flow sensor 2, the refrigerant enters the condenser 8 through the pipeline and the connecting pipe 10. A fan is provided on the condenser 3. At this time, the fan will cool the gaseous refrigerant, allowing the gaseous refrigerant to cool and condense into a liquid state to release heat. Then the refrigerant passes through the expansion valve 4 again. The liquid refrigerant passes through the expansion valve 4, and the pressure drops sharply, and the temperature drops accordingly, becoming a low-pressure, low-temperature liquid refrigerant. At the same time, the expansion valve 4 can also adjust the flow of the refrigerant. Then the refrigerant enters the evaporator 5, so that the refrigerant absorbs heat from the indoor air, evaporates the refrigerant into a gaseous state, and then enters the compressor 1. This cycle can achieve the effect of cooling the room.

[0033] The temperature data monitored by the first temperature sensor and the second temperature sensor will be transmitted to the controller 7, and the controller 7 can intelligently adjust the refrigerant flow rate through the data. The higher the temperature, the greater the refrigerant flow rate. At the same time, when the temperature sensor 6 senses that the indoor temperature has reached a preset value, it will transmit the data to the controller 7. At this time, the controller 7 will turn off the air conditioner and stop the flow of refrigerant. When the room temperature rises to a certain value, the temperature sensor 6 will transmit the temperature rise value to the controller 7 again, allowing the controller 7 to start the air conditioner and make the refrigerant flow again. Through the above-mentioned mechanism, when the air conditioner cools down the room, the refrigerant flow rate can be adjusted according to the room temperature to achieve the effect of saving energy. At the same time, when the preset room temperature is reached, the controller 7 will turn off the air conditioner to stop the flow of refrigerant, thereby achieving the effect of greatly saving energy.

[0034] The bottom surface of the inner wall of the hollow block 9 is fixedly connected with a hollow connecting block 11, the top of the connecting block 11 is connected with a conduit 12, the central part of the conduit 12 is aligned with the central part of the condenser 8, and the conduit 12 is sealed and slidably connected with an elastic cleaning block 15, the cleaning block 15 is circular, a guide rod 14 is provided in the condenser 8, both ends of the guide rod 14 extend into the hollow block 9, the cleaning block 15 is sealed and slidably connected with the surface of the guide rod 14, a round tube 18 is connected in the connecting block 11, the air inlet end of the round tube 18 can be externally connected to an air pump, a sealing mechanism for sealing the connecting tube 10 is provided in the hollow block 9, and a discharge mechanism for removing impurities is provided in the conduit 12;

[0035] In the refrigerant flow control system of the present application, multiple devices are connected by pipelines to allow the refrigerant to flow. However, after long-term use, dust, dirt and other particles in the external environment will enter the pipeline from the connection of the pipeline of a certain device. These impurities will enter the condenser 8 from the air inlet end of the condenser 8 and then accumulate inside the pipeline. The accumulation of these particles will reduce the effective channel of the pipeline, increase the resistance to the flow of the refrigerant, and thus affect the efficiency of the air conditioner. At the same time, during the refrigeration process, the lubricating oil may flow with the refrigerant, but in the condenser 3, oil separation may cause oil to deposit in the pipeline, further increasing the resistance to the flow of the refrigerant.

[0036] When the condenser tube 8 needs to be cleaned, the present application can seal the connecting tube 10 at the inlet end of the condenser tube 8 with the help of a sealing mechanism, and then use an air pump to transport gas into the circular tube 18. The air pump is a two-way air pump that can discharge and inhale gas. The gas will enter the connecting block 11 from the circular tube 18, and then the gas will push the cleaning block 15, so that the cleaning block 15 enters the condenser tube 8. The elastic side wall of the cleaning block 15 will be sealed and fitted with the inner wall of the condenser tube 8. When the cleaning block 15 is detached from the conduit 12, the gas will enter the hollow block 9 from the conduit 12, and then continue to push the cleaning block 15, so that the cleaning block 15 moves in the condenser tube 8. At this time, the cleaning block 15 will clean the inner wall of the condenser tube 8. When the cleaning block 15 moves to the outlet end, the cleaned impurities will be pushed into the conduit 12 at the outlet end, and then be discharged by the discharging mechanism, and then the sealing mechanism will no longer seal the connecting tube 10 at the inlet end.

[0037] Afterwards, the cleaning block 15 will enter the conduit 12 set at the outlet end under the push of the gas. At this time, the air pump at the inlet end is closed, and then the air pump at the outlet end is started to suction, so that the cleaning block 15 is completely sucked into the conduit 12 to prevent clogging of the condenser 8. When the condenser 8 needs to be cleaned again, it is only necessary to swap the use order of the inlet and outlet air pumps. At the same time, the connecting pipe 10 at the outlet end is sealed at this time. The above mechanism can achieve the effect of cleaning the inner wall of the condenser 8, so that the refrigerant can flow smoothly in the condenser 8, thereby reducing the energy loss of the air conditioner operation.

[0038] The sealing mechanism includes a connecting hole 17 provided on the side wall of the hollow block 9, the connecting pipe 10 is connected to the connecting hole 17, a first slide groove connected to the connecting hole 17 is provided on the hollow block 9, a first sealing plate 16 is slidably connected to the inner wall of the first slide groove, a first spring is fixedly connected between the top surface of the first sealing plate 16 and the inner wall of the first slide groove, and a moving component for driving the first sealing plate 16 to move is arranged in the conduit 12; when the connecting pipe 10 is sealed, the present application can use the moving component to move the first sealing plate 16 downward, at this time the first sealing plate 16 will block the connecting pipe 10, so that the connecting pipe 10 is sealed, and at this time the gas injected into the hollow block 9 from the air pump will push the cleaning block 15 in the condenser 8 to move.

[0039] The moving assembly includes a ring 20 fixedly connected to the inner wall of the conduit 12, the inner part of the ring 20 is a hollow structure, and the bottom end of the ring 20 is sealed and slidably connected with a pressure ring 21, a second spring is fixedly connected between the top surface of the pressure ring 21 and the ring 20, the inner wall of the conduit 12 is sealed and slidably connected with a disk 22 made of elastic material, a group of shrinkage holes are opened on the disk 22, a third spring is fixedly connected between the bottom surface of the disk 22 and the connecting block 11, and a hose 19 is connected between the ring 20 and the first slide groove; when the air pump is used to inject air into the connecting block 11, the gas will first push the disk 22, and then the disk 22 will move upward to push the pressure ring 21, so that The pressure ring 21 pushes the gas in the ring 20 from the hose 19 into the first slide groove. At this time, the gas will push the first sealing plate 16 to seal the connecting pipe 10. As the gas is continuously injected into the connecting block 11, the disc 22 will be blocked by the pressure ring 21. At this time, the shrinkage hole on the disc 22 will open under the action of air pressure. At this time, the gas will be discharged from the shrinkage hole to push the cleaning block 15 to move. When the air pump is turned off, the third spring will pull the disc 22 to reset. At this time, the disc 22 no longer squeezes the pressure ring 21. At this time, the gas in the first slide groove can flow back into the ring 20, so that the first sealing plate 16 is reset under the pull of the first spring, thereby no longer sealing the connecting pipe 10.

[0040] The side wall of the conduit 12 near the port is twisted with a group of guide pieces 13 tilted upward by a torsion spring, and the side of the guide pieces 13 close to each other is fixedly connected with an elastic connecting piece 24, and the side of the guide piece 13 near the conduit 12 is fixedly connected with a magnetic piece 23, and the cleaning block 15 is fixedly connected with a magnetic ring 26 that is magnetically attracted to the magnetic piece 23; in the present application, the guide piece 13 can guide the impurities discharged from the outlet end of the condenser tube 8, so that the impurities can enter the conduit 12 and then be discharged by the discharging mechanism, and then in the process of the cleaning block 15 entering the conduit 12, the magnetic ring 26 will be magnetically attracted to the magnetic piece 23, so that the guide piece 13 rotates, increasing the inclination angle of the guide piece 13, so that the impurities on the guide piece 13 can slide into the conduit 12, and then after the magnetic ring 26 on the cleaning block 15 passes over the magnetic piece 23, the guide piece 13 will be reset under the action of the torsion spring, and at the same time shake, so that the impurities on the guide piece 13 are shaken off into the conduit 12, thereby improving the effect of impurity collection.

[0041] The interior of the connecting piece 24 is a hollow structure, and a group of upwardly inclined air outlet holes 25 are provided on one side of the connecting piece 24 close to the conduit 12; when the guide piece 13 in the present application rotates, it will squeeze the connecting piece 24, and at this time, the gas in the connecting piece 24 can be blown from the air outlet holes 25 to the cleaning surface of the cleaning block 15, thereby blowing impurities into the conduit 12, and at the same time, when the guide piece 13 shakes, the gas in the connecting piece 24 will be repeatedly squeezed and blown onto the cleaning block 15.

[0042] The discharging mechanism includes a discharging rail 27, the feeding end of the discharging rail 27 is connected to the side wall of the conduit 12, the discharging end of the discharging rail 27 is sealed and passes through the side wall of the hollow block 9, the conduit 12 is provided with a second chute at a position corresponding to the discharging rail 27, the inner wall of the second chute is slidably connected with a second sealing plate 29 for sealing the discharging rail 27, a fourth spring is fixedly connected between the bottom surface of the second sealing plate 29 and the second chute, and the second sealing plate 29 is made of magnetic material, the top surface of the disc 22 is inclined, and a magnetic ring 28 that is magnetically attracted to the second sealing plate 29 is fixedly connected inside the disc 22;

[0043] When the second sealing plate 29 in the present application is in a normal state, it will seal the discharge rail 27. When the discharge rail 27 needs to be opened, the disc 22 can be sucked downward by an air pump. At this time, the magnetic ring 28 will pass through the second sealing plate 29 and magnetically attract it, thereby driving the second sealing plate 29 to move downward, so that the second sealing plate 29 no longer seals the discharge rail 27. Then, when the lowest point of the inclined surface at the top of the disc 22 is aligned with the bottom surface of the discharge rail 27, the air pump stops working. At this time, impurities entering the conduit 12 will slide from the inclined surface of the disc 22 to the discharge rail 27 for sealing. After that, the air pump can be allowed to inject air into the circular tube 18, so that the disc 22 moves upward and drives the second sealing plate 29 to seal the discharge rail 27.

[0044] Embodiment 2: Figure 7 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: the interior of the cleaning block 15 is provided with a hollow groove 30 and a connecting groove 31 which are interconnected, a push ring is sealingly and slidably connected in the connecting groove 31, a magnetic plate 32 is fixedly connected to the bottom surface of the push ring, an electromagnet 33 which repels the magnetic plate 32 is fixedly connected to the inner bottom surface of the connecting groove 31, a through hole which is connected to the connecting groove 31 is provided on the bottom surface of the cleaning block 15, a fifth spring is fixedly connected between the bottom surface of the push ring and the inner wall of the connecting groove 31, and a micro camera is provided at the cleaning end of the cleaning block 15;

[0045] When the cleaning block 15 in the present application moves in the condenser 8, it will pass through the bend. The position of the cleaning block 15 is observed by a micro camera. When reaching the bend, the magnet of the electromagnet 33 can be reduced so that the second spring pull box moves close to the side of the electromagnet 33 to attract the magnetic plate 32. At this time, the magnetic plate 32 will suck the gas in the hollow groove 30, so that the end of the cleaning block 15 that is about to enter the bend will shrink, so that the cleaning block 15 can better enter the bend. The magnetic force of the electromagnet 33 can be adjusted. When the cleaning block 15 moves in the horizontal plane of the condenser 8, the magnetic force of the electromagnet 33 can be increased so that the push ring pushes the gas into the hollow groove 30. At this time, the cleaning end will expand, so as to better fit with the condenser 8, so as to improve the effect of cleaning the condenser 8.

[0046] The cleaning end of the cleaning block 15 is fixedly connected with a hollow elastic ring 36, and a fixed pipe 34 is connected between the elastic ring 36 and the connecting groove 31. A pressure valve is arranged in the fixed pipe 34, and a cleaning liquid is stored in the elastic ring 36. A group of shrinkage holes evenly distributed in an annular shape are opened on the side wall of the elastic ring 36, and a sealing rod 35 for sealing the through hole is fixedly connected to the bottom surface of the push ring; when the cleaning ring in the present application encounters grease that is difficult to clean, the magnetic force of the electromagnet 33 can be reduced, so that the push ring moves downward under the pull of the fifth spring, so that the sealing rod 35 seals the through hole, and then the push ring continues to move downward, pushing the gas in the connecting groove 31 into the fixed pipe 34, at this time the pressure valve will be pushed open, and then the gas will enter the elastic ring 36, thereby expanding the shrinkage holes in the elastic ring 36, so that the cleaning liquid flows to the grease for decomposition, and then the cleaning block 15 passes through the grease to clean it off.

[0047] An expansion ring 37 is fixedly connected to the inner wall of the elastic ring 36, and a group of bristles 38 are fixedly connected to the side wall of the elastic ring 36; in the present application, the cleaning liquid in the elastic ring 36 will decrease after use, and the liquid level of the cleaning liquid will decrease, resulting in the liquid level of the cleaning liquid being unable to reach the shrinkage hole. At this time, the expansion ring 37 can be used to push the cleaning liquid to fill the elastic ring 36 when the cleaning liquid decreases, so that the cleaning liquid can be discharged normally. At the same time, the bristles 38 can also be used to improve the cleaning effect on the inner wall of the condenser 8.

[0048] Working principle: The temperature data monitored by the first temperature sensor and the second temperature sensor of the present invention will be transmitted to the controller 7. The controller 7 can intelligently adjust the refrigerant flow rate through the data. The higher the temperature, the greater the refrigerant flow rate. At the same time, when the temperature sensor 6 senses that the indoor temperature has reached a preset value, it will transmit the data to the controller 7. At this time, the controller 7 will turn off the air conditioner and stop the flow of refrigerant. When the room temperature rises to a certain value, the temperature sensor 6 will transmit the temperature rise value to the controller 7 again, so that the controller 7 will start the air conditioner and make the refrigerant flow again. Through the above mechanism, when the air conditioner cools down the room, the refrigerant flow rate can be adjusted according to the room temperature to achieve the effect of saving energy. At the same time, when the preset room temperature is reached, the controller 7 will turn off the air conditioner to stop the flow of refrigerant, thereby achieving the effect of greatly saving energy.

[0049] When the condenser tube 8 needs to be cleaned, the present application can seal the connecting tube 10 at the inlet end of the condenser tube 8 with the help of a sealing mechanism, and then use an air pump to transport gas into the circular tube 18. The air pump is a two-way air pump that can discharge and inhale gas. The gas will enter the connecting block 11 from the circular tube 18, and then the gas will push the cleaning block 15, so that the cleaning block 15 enters the condenser tube 8. The elastic side wall of the cleaning block 15 will be sealed and fitted with the inner wall of the condenser tube 8. When the cleaning block 15 is detached from the conduit 12, the gas will enter the hollow block 9 from the conduit 12, and then continue to push the cleaning block 15, so that the cleaning block 15 moves in the condenser tube 8. At this time, the cleaning block 15 will clean the inner wall of the condenser tube 8. When the cleaning block 15 moves to the outlet end, the cleaned impurities will be pushed into the conduit 12 at the outlet end, and then be discharged by the discharging mechanism, and then the sealing mechanism will no longer seal the connecting tube 10 at the inlet end.

[0050] The cleaning block 15 will enter the conduit 12 provided at the outlet end under the push of the gas. At this time, the air pump at the inlet end is turned off, and then the air pump at the outlet end is started to suck air, so that the cleaning block 15 is completely sucked into the conduit 12 to prevent the condenser tube 8 from being blocked. When the condenser tube 8 needs to be cleaned again, it is only necessary to exchange the use order of the air pumps at the inlet end and the outlet end. At the same time, the connecting pipe 10 at the outlet end is sealed at this time. The effect of cleaning the inner wall of the condenser tube 8 is achieved through the above mechanism, so that the refrigerant can flow smoothly in the condenser tube 8, thereby reducing the energy loss of the air conditioner operation;

[0051] When the present application is sealing the connecting pipe 10, the first sealing plate 16 can be moved downward with the help of a moving assembly. At this time, the first sealing plate 16 will block the connecting pipe 10, so that the connecting pipe 10 is sealed. At this time, the gas injected from the air pump into the hollow block 9 will push the cleaning block 15 in the condenser tube 8 to move; when the present application uses the air pump to inject gas into the connecting block 11, the gas will first push the disc 22. At this time, the disc 22 will move upward to push the pressure ring 21, so that the pressure ring 21 pushes the gas in the ring 20 from the hose 19 into the first slide groove. At this time, the gas will push the second A sealing plate 16 seals the connecting pipe 10. As the gas is continuously injected into the connecting block 11, the disc 22 will be blocked by the pressure ring 21. At this time, the shrinkage hole on the disc 22 will open under the action of the gas pressure. At this time, the gas will be discharged from the shrinkage hole to push the cleaning block 15 to move. When the air pump is turned off, the third spring will pull the disc 22 to reset. At this time, the disc 22 no longer squeezes the pressure ring 21. At this time, the gas in the first slide groove can flow back into the ring 20, so that the first sealing plate 16 is reset under the pull of the first spring, thereby no longer sealing the connecting pipe 10;

[0052] In the present application, the guide piece 13 can guide the impurities discharged from the outlet end of the condenser tube 8, so that the impurities can enter the conduit 12 and then be discharged by the discharging mechanism. Then, when the cleaning block 15 enters the conduit 12, the magnetic ring 26 will be magnetically attracted to the magnetic piece 23, so that the guide piece 13 rotates, increasing the inclination angle of the guide piece 13, so that the impurities on the guide piece 13 can slide into the conduit 12. Then, after the magnetic ring 26 on the cleaning block 15 passes over the magnetic piece 23, the guide piece 13 will be reset under the action of the torsion spring and shake at the same time, so that the impurities on the guide piece 13 will be shaken off into the conduit 12, thereby improving the effect of collecting impurities.

[0053] When the guide piece 13 in the present application rotates, it will squeeze the connecting piece 24. At this time, the gas in the connecting piece 24 can be blown from the air outlet 25 to the cleaning surface of the cleaning block 15, thereby blowing the impurities into the conduit 12. At the same time, when the guide piece 13 is shaken, the gas in the connecting piece 24 will be repeatedly squeezed and blown onto the cleaning block 15; when the second sealing plate 29 in the present application is in a normal state, it will seal the discharge rail 27. When the discharge rail 27 needs to be opened, the disc 22 can be sucked downward by an air pump. At this time, the magnetic ring 2 8 will pass through the second sealing plate 29 and be magnetically attracted to it, thereby driving the second sealing plate 29 to move downward, so that the second sealing plate 29 no longer seals the discharge track 27, and then when the lowest point of the inclined surface at the top of the disc 22 is aligned with the bottom surface of the discharge track 27, the air pump stops working. At this time, the impurities entering the conduit 12 will slide from the inclined surface of the disc 22 to the discharge track 27 for sealing, and then the air pump can be allowed to inject air into the circular tube 18, so that the disc 22 moves upward and drives the second sealing plate 29 to seal the discharge track 27.
