For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The throttling devices currently used in air-conditioning systems on the market include manual expansion valves, float expansion valves, thermal expansion valves, electronic expansion valves, capillaries, throttling short tubes and other devices. The principles of these devices are similar, which is to reduce the refrigerant pressure through resistance to achieve throttling. This results in the pressure loss being unable to be utilized and being lost in vain, causing energy waste.

[0035] In order to solve the above problems, the present application provides a refrigerant throttling pressure loss recovery and utilization device, which includes a shell 1, a fan blade 2, a coil assembly 3 and a magnet assembly 5. Among them, both ends of the shell 1 are connected to the internal system of the air conditioner so that the refrigerant pressure in the internal system of the air conditioner enters the shell 1, the magnet assembly 5 is installed on the outer wall of the shell 1 to generate a magnetic field, the fan blade 2 is installed inside the shell 1, and the outer edge of the fan blade 2 is installed with the coil assembly 3. Among them, the fan blade 2 can be driven to rotate by the refrigerant pressure so that the coil assembly 3 can make a cutting line motion on the magnetic field to generate current.

[0036] The technical solution provided in the present application connects the outer shell 1 and the internal system of the air conditioner so that the refrigerant pressure in the internal system of the air conditioner enters the outer shell 1 and drives the fan blades 2 installed inside the outer shell 1 to rotate. In this way, the coil assembly 3 installed on the fan blades 2 performs a cutting line motion on the magnetic field generated by the magnet assembly 5 installed on the outer wall of the outer shell 1 to generate current, thereby effectively utilizing the refrigerant pressure and avoiding energy waste.

[0037] Combine the following Figures 1 to 4 The refrigerant throttling pressure loss recovery and utilization device of the present application is described.

[0038] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The first aspect of the present invention provides a refrigerant throttling pressure loss recovery and utilization device, which generally includes a shell 1, a fan blade 2, a coil assembly 3 and a magnet assembly 5. Among them, both ends of the shell 1 are connected to the internal system of the air conditioner so that the refrigerant pressure in the internal system of the air conditioner enters the shell 1, the magnet assembly 5 is installed on the outer wall of the shell 1 to generate a magnetic field, the fan blade 2 is installed inside the shell 1, and the coil assembly 3 is installed on the outer edge of the fan blade 2. Among them, the fan blade 2 can be driven to rotate by the refrigerant pressure so that the coil assembly 3 performs a cutting line motion on the magnetic field to generate current. By converting the refrigerant pressure loss into electrical energy, this part of the energy loss can be recovered and reused.

[0039] In this way, by connecting the housing 1 and the internal system of the air conditioner, the refrigerant pressure of the internal system of the air conditioner enters the housing 1 and drives the fan blades 2 installed inside the housing 1 to rotate, so that the coil assembly 3 installed on the fan blades 2 performs a cutting line motion on the magnetic field generated by the magnet assembly 5 installed on the outer wall of the housing 1 to generate current, effectively utilize the refrigerant pressure, and avoid energy waste. In addition, the refrigerant throttling pressure loss recovery and utilization device has the advantages of simple structure, easy processing and installation, and small space occupation.

[0040] Among them, the refrigerant throttling pressure loss recovery device of the present application will not reduce the refrigerant pressure through manual expansion valves, float expansion valves, thermal expansion valves, electronic expansion valves, capillaries, throttling short tubes and other devices, but will keep the refrigerant pressure at the original pressure and utilize this part of the pressure.

[0041] Continue reading Figure 1 , Figure 2 , Figure 3 and Figure 4 Specifically, one end of the housing 1 is connected to one end of the pipeline of the internal system of the air conditioner, and the other end of the housing 1 is connected to the other end of the pipeline of the internal system of the air conditioner, so that the refrigerant pressure can pass through the housing 1. The magnet assembly 5 can be installed on the outer wall of the housing 1 by welding or screws and generate a magnetic field. The fan blade 2 can be rotatably installed inside the housing 1. The fan blade 2 is driven to rotate after contacting the refrigerant pressure, so that the coil assembly 3 installed on the outer edge of the fan blade 2 can cut the magnetic field and generate current.

[0042] See also Figure 1 In the above-mentioned embodiment of the refrigerant throttling pressure loss recovery and utilization device, the shell 1 generally includes an integrally formed cylinder 11, a first side interface portion 12 and a second side interface portion 13. Among them, the first side interface portion 12 includes a first inclined section 122 and a first straight section 121 formed on one side of the cylinder 11, and the first straight section 121 is plugged into one end of the pipe of the internal system of the air conditioner so that the refrigerant pressure enters the shell 1. The second side interface portion 13 includes a second inclined section 132 and a second straight section 131 formed on the other side of the cylinder 11, and the second straight section 132 is plugged into the other end of the pipe of the internal system of the air conditioner so that the refrigerant pressure enters the shell 1.

[0043] In this way, the first straight section 121 is inserted into one end of the pipe of the internal system of the air conditioner to realize the connection between the cylinder 11 and the internal system of the air conditioner, so that the refrigerant pressure enters the outer shell 1, and one end of the pipe abuts against the bottom end of the first inclined section 122 to play a limiting role. The second straight section 131 is inserted into the other end of the pipe of the internal system of the air conditioner to realize the connection between the cylinder 11 and the internal system of the air conditioner, so that the refrigerant pressure discharges from the outer shell 1, and the other end of the pipe abuts against the bottom end of the second inclined section 132 to play a limiting role.

[0044] Specifically, the first straight section 121 and one end of the pipe of the internal system of the air conditioner can be welded to have good sealing performance to avoid leakage, or can be flexibly connected through threads and sealing gaskets to facilitate disassembly and maintenance. The second straight section 131 and the other end of the pipe of the internal system of the air conditioner can be welded to have good sealing performance to avoid leakage, or can be flexibly connected through threads and sealing gaskets to facilitate disassembly and maintenance.

[0045] Continue reading Figure 1 In the preferred embodiment of the refrigerant throttling pressure loss recovery and utilization device, the barrel 11, the first inclined section 122, the first straight section 121, the second inclined section 132 and the second straight section 131 are made of the same material and are integrally constructed by a mold. The first inclined section 122 and the second inclined section 132 are arranged in opposite directions and at the same angle. The first straight section 121 and the second straight section 131 have the same diameter, which is smaller than the diameter of the barrel 11, so that the outer shell 1 is formed into a shape with thin ends and thick in the middle to facilitate the entry of refrigerant pressure, while increasing the rotation space of the fan blades 2.

[0046] See also Figure 4 In the embodiment of the refrigerant throttling pressure loss recovery and utilization device, a fan blade through hole 21 is provided in the middle of the fan blade 2, and the fan blade 2 is installed inside the housing 1 through a fan bracket 4. The fan bracket 4 generally includes a first support structure 41, a second support structure 43 and a connecting shaft 42. Among them, the first support structure 41 is installed inside the first end of the housing 1, the second support structure 42 is installed inside the second end of the housing 1, the connecting shaft 42 is arranged inside the housing 1 and inserted into the fan blade through hole 21, one end of the connecting shaft 42 is connected to the first support structure 41, and the other end of the connecting shaft 42 is connected to the second support structure 43.

[0047] In this way, by setting the first supporting structure 41 and the second supporting structure 43, the connecting shaft 42 is used to install the connecting shaft 42, which is inserted into the fan blade through hole 21 for installing the fan blade 2, so that the fan blade 2 rotates inside the housing 1 to achieve the purpose of supporting the fan blade 2.

[0048] Specifically, the first support structure 41 and the second support structure 43 are both in a cross shape or a straight shape, which can be determined according to the needs. The first support structure 41 is welded between the first inclined section 122 and the first straight section 121, and the second support structure 43 is welded between the second inclined section 132 and the second straight section 131, so that the fan blades 2 can only rotate in the cylinder 11, avoiding the problem of the fan blades 2 contacting the first inclined section 122 and the second inclined section 132 when rotating. One end of the connecting shaft 42 is welded to the center position of the first support structure 41, and the other end of the connecting shaft 42 is welded to the center position of the second support structure 43, so that the connecting shaft 42 is arranged in a straight line along the axial direction of the cylinder 11 to avoid the fan blades 2 from being offset. The connecting shaft 42 is inserted into the fan blade through hole 21, and the fan blades 2 can move on the connecting shaft 42.

[0049] As a possible implementation, the fan bracket 4 also includes a limiting structure (not shown in the figure), which generally includes a first thread, a first limiting hoop, a second thread, and a second limiting hoop. Among them, the first thread is opened on one side of the middle of the connecting shaft 42, the first limiting hoop is connected to the first thread, the second thread is opened on the other side of the middle of the connecting shaft 42, the second limiting hoop is connected to the second thread, and the fan blade through hole 21 of the fan blade 2 is located in the middle of the connecting shaft 42 and between the first limiting hoop and the second limiting hoop, which is used to limit the fan blade 2 to the middle of the connecting shaft 42, to prevent the fan blade 2 from sliding on the connecting shaft 42 over a large range to produce abnormal noise, and to form a limit.

[0050] See also Figure 2 , Figure 3 and Figure 4 In the preferred embodiment of the above-mentioned refrigerant throttling pressure loss recovery and utilization device, the fan blades 2 have four blades or three blades. Technical personnel in this field can choose whether to use four blades, three blades, or five blades according to the size of the cylinder 11 and the pressure value of the refrigerant. The specific number of blades can be determined according to actual conditions.

[0051] Furthermore, the fan blades are formed with an inclined angle so as to increase the rotation speed of the fan blades 2 when the refrigerant pressure contacts the fan blades. The above-mentioned inclined angle is 30° to 60°, preferably 45°, so that the coil assembly 3 can realize the movement and rotation of cutting the magnetic flux lines.

[0052] The shape and size of the fan blades can be determined according to requirements.

[0053] See also Figure 2 In the preferred embodiment of the above-mentioned refrigerant throttling pressure loss recovery and utilization device, the coil assembly 3 generally includes a copper wire and an insulating protective cover. An insulating protective cover is provided on the outside of the copper wire. By providing an insulating protective cover on the outside of the copper wire to avoid leakage, a closed coil is formed, which cuts the magnetic flux lines in the magnetic field to generate current.

[0054] Specifically, a groove is processed on the outer edge of the fan blade 2, and the coil assembly 3 is installed in the groove in a win-win manner and fixed by glue.

[0055] It should be noted that the present invention does not impose any restriction on the thickness of the copper wire, as long as it can complete the movement of cutting the magnetic flux lines. Those skilled in the art can set it according to actual conditions.

[0056] See also Figure 1 and Figure 2 In the preferred embodiment of the refrigerant throttling pressure loss recovery and utilization device, the magnet assembly 5 includes a positive magnet block 51 and a negative magnet block 52, and the positive magnet block 51 and the negative magnet block 52 are symmetrically fixed to the outer wall of the housing 1. By symmetrically installing the positive magnet block 51 and the negative magnet block 52 on the outer wall of the housing 1 to generate a magnetic field, the copper wire can cut the magnetic flux line when the fan blade 2 rotates, thereby generating current.

[0057] Specifically, the positive magnet block 51 and the negative magnet block 52 have the same shape and size to generate a magnetic field. The positive magnet block 51 and the negative magnet block 52 are generally embedded in the outside of the cylinder 11, or fixed to the outside of the cylinder 11 by screws or glue.

[0058] More specifically, the positive pole magnet block 51 and the negative pole magnet block 52 are both rectangular bodies, and the contact surfaces of the positive pole magnet block 51, the negative pole magnet block 52 and the cylinder 11 are all arc-shaped surfaces, the curvature of the arc-shaped surfaces is consistent with the curvature of the outer wall of the cylinder 11, so that the connection between the positive pole magnet block 51, the negative pole magnet block 52 and the cylinder 11 is more tightly.

[0059] See also Figure 1 In the above-mentioned alternative embodiment of the refrigerant throttling pressure loss recovery and utilization device, the device further includes a first wire 6 and a second wire 7. The first wire 6 is inserted on one side of the housing 1 and extends inside the housing 1 to contact the first support structure 41 for conducting electricity; the second wire 7 is inserted on the other side of the housing 1 and extends inside the housing 1 to contact the second support structure 43 for conducting electricity. The generated current is derived through the first wire 6 and the second wire 7 for use.

[0060] Specifically, the first conductor 6 is installed in the hole between the first inclined section 122 and the first straight section 121, and is in contact with or connected to the first support structure 41 to transmit current. The second conductor 7 is installed in the hole between the second inclined section 132 and the second straight section 131, and is in contact with or threadedly connected to the second support structure 43 to transmit current.

[0061] The refrigerant throttling pressure loss recovery and utilization device of the present application is a device that converts the pressure potential energy of the refrigerant coming out of the condenser into electrical energy. In the air conditioning system, the refrigerant originally coming out of the condenser is a high-pressure liquid refrigerant. Due to the high pressure, the refrigerant cannot be completely evaporated in the evaporator. The existing method is to release this part of the pressure through resistance through a throttling device to achieve the purpose of reducing pressure, so this part of the refrigerant pressure will be wasted. The refrigerant throttling pressure loss recovery and utilization device of the present application uses this part of the pressure to realize the conversion of pressure potential energy into electrical energy and realize energy recycling and reuse. The output of electrical energy is mainly achieved by cutting the magnetic flux lines by the coil assembly 3. The difference between the device and the generator is that the middle rotating rotor is composed of a fan blade 2 and a coil assembly 3. When the refrigerant flows through the fan blade 2, it will drive the fan blade 2 to rotate, so the coil assembly 3 arranged in the fan blade 2 will cut the magnetic flux lines in the magnetic field. When the coil assembly 3 cuts the magnetic flux lines, there will be a current flowing in the coil assembly 3, and then the first wire 6 and the second wire 7 will lead out this part of the current for reuse.

[0062] In a second aspect, the present invention provides an air conditioner, comprising the refrigerant throttling pressure loss recovery and utilization device of the first aspect.

[0063] The air conditioner of this technical solution includes a refrigerant throttling pressure loss recovery and utilization device as in any technical solution of the present invention, and thus it has all the technical effects of a refrigerant throttling pressure loss recovery and utilization device as in any technical solution of the present invention.

[0064] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
