Abstract
Description
Technical Field
[0001] This invention relates to the technical field of air conditioning, and specifically provides an air conditioning system. Background Technology
[0002] Air conditioning systems are commonly used electrical devices with a wide range of applications. An air conditioning system includes a compressor, a first heat exchanger, an expansion valve, a second heat exchanger, and a purification device. The compressor, first heat exchanger, expansion valve, and second heat exchanger are connected sequentially through pipes, forming a circulation loop filled with refrigerant. The compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The first heat exchanger liquefies the high-temperature, high-pressure gaseous refrigerant into a medium-temperature, medium-pressure liquid refrigerant, releasing heat to the outside. The liquid refrigerant enters the expansion valve for throttling, then absorbs heat in the second heat exchanger, causing the liquid refrigerant to evaporate and return to a gaseous state. It then re-enters the compressor for compression and pressurization, repeating this cycle to achieve cooling or heating. An air conditioning system that uses the second heat exchanger for cooling is called a refrigeration unit, and a system that uses the first heat exchanger for heating is called a heating unit.
[0003] Conventional air conditioning systems utilize flowing air to exchange heat with a second or first heat exchanger to achieve cooling or heating. In water-cooled air conditioning systems, a water circulation system is also included. This system uses a second or first heat exchanger within the air conditioning system to exchange heat with the water circulation system, causing temperature changes in the water circulation system. The water circulation system includes coils and a fan. The fan circulates air, exchanging heat with the coils to regulate the air temperature and achieve cooling or heating.
[0004] In the air conditioning systems mentioned above, compressors are used to perform heating. However, the heating efficiency of compressors is generally between 70% and 85%, which is relatively low, resulting in low energy utilization.

[0032] Example 1
[0033] To address the problem of low energy utilization in existing air conditioning systems during heating, this invention provides an air conditioning system, primarily for residential use. For example... Figure 1 As shown, the air conditioning system includes a heat exchange fan, an outdoor fan, a compressor 1, a first heat exchanger 2, an expansion valve 3, a second heat exchanger 4, and a four-way reversing valve 5. The compressor 1, first heat exchanger 2, expansion valve 3, and second heat exchanger 4 are sequentially connected via pipes, forming a circulation loop filled with refrigerant. The four-way reversing valve 5 is located at the outlet end of the compressor 1 and is used to switch the flow path of the refrigerant flowing from the outlet of the compressor 1. The pipe connecting the compressor 1 and the first heat exchanger 2 is called the refrigerant piping.
[0034] In heating mode, the refrigerant flowing out of the compressor 1 outlet flows sequentially through the four-way reversing valve 5 to the first heat exchanger 2, the expansion valve 3, and the second heat exchanger 4 before returning to the compressor 1. At this time, the compressor 1 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The first heat exchanger 2 liquefies the high-temperature, high-pressure gaseous refrigerant into a medium-temperature, medium-pressure liquid refrigerant and releases heat to the outside. After the liquid refrigerant enters the expansion valve 3 for throttling, it absorbs heat through the second heat exchanger 4, causing the liquid refrigerant to evaporate and form a gaseous state. It then enters the compressor 1 again for compression and pressurization. This cycle repeats continuously, using the heat generated by the first heat exchanger 2 for heating. In cooling mode, the refrigerant flowing out of compressor 1 flows through the second heat exchanger 4, expansion valve 3 and first heat exchanger 2 in sequence after being acted upon by the four-way reversing valve 5. Compressor 1 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant is liquefied into a medium-temperature, medium-pressure liquid refrigerant through the second heat exchanger 4 and releases heat to the outside. After the liquid refrigerant enters the expansion valve 3 for throttling, it absorbs heat through the first heat exchanger 2, causing the liquid refrigerant to evaporate and form a gaseous state. It then enters the compressor 1 again for compression and pressurization. This cycle repeats continuously, using the first heat exchanger 2 to absorb heat for cooling.
[0035] The air blown out by the heat exchange fan can exchange heat with the first heat exchanger 2, so that the air conditioning system blows out hot air in heating mode and cold air in cooling mode. The outdoor fan is used to blow air to the second heat exchanger 4, so as to increase the airflow around the second heat exchanger 4, thereby increasing the speed of heat exchange between the surrounding air and the second heat exchanger 4, so that the second heat exchanger 4 can accelerate heat absorption in heating mode and accelerate heat dissipation in cooling mode.
[0036] The air conditioning system of the present invention mainly adopts the operation mode of using the first heat exchanger 2 to release heat for heating. Without departing from the principle of the present invention, in other embodiments, those skilled in the art can remove the four-way reversing valve 5 so that the air conditioning system only uses the first heat exchanger 2 to release heat for heating, i.e., single heating mode.
[0037] In addition, the air conditioning system also includes an alternating magnetic field source 7, which generates an alternating magnetic field. A portion of the refrigerant piping connecting the compressor 1 and the first heat exchanger 2 is located within the alternating magnetic field. This refrigerant piping within the alternating magnetic field is called the heating piping 8. The heating piping 8 is a metal pipe, typically copper. Under the electromagnetic induction of the alternating magnetic field, the heating piping 8 generates an eddy current, which raises the temperature of the heating piping 8, thereby increasing the temperature of the refrigerant flowing through it. In heating mode, the refrigerant liquefies at the first heat exchanger 2, releasing heat to raise the temperature of the first heat exchanger 2 through heat exchange. The heat released by the refrigerant comes from the work done by the compressor 1 and the work done by the alternating magnetic field. The heating power of the compressor 1 is between 70% and 85%, while the heating power of the alternating magnetic field is above 90%. Utilizing the alternating magnetic field to assist in heating the heating piping 8 reduces the operating power of the compressor 1, thereby improving the energy utilization rate of the air conditioning system during the heating process.
[0038] The heating pipe 8 is specifically a coil or a serpentine tube to increase its length within the alternating magnetic field. The longer the heating pipe 8 is within the alternating magnetic field, the greater the induced current generated by the change in the alternating magnetic field within the heating pipe 8, resulting in better heating performance. Insulating sleeves are installed at the ends of the heating pipe 8 to prevent the induced current generated by the heating pipe 8 from being conducted to other components, ensuring that the induced current is fully utilized to raise the temperature of the heating pipe 8 and improve heating efficiency.
[0039] Specifically, such as Figure 2 As shown, the outdoor fan is equipped with an impeller 9, which includes multiple blades 91. The alternating magnetic field source 7 includes a first magnet 92 and a second magnet 93, which are arranged alternately along the circumference. Each blade 91 is embedded with at least one first magnet 92 or at least one second magnet 93. The polarities of the first magnet 92 and the second magnet 93 on the same side of the blade 91 are opposite. After the impeller 9 rotates, it can generate an alternating magnetic field.
[0040] Specifically, the first magnet 92 and the second magnet 93 are electromagnets, which become magnetic when energized. The air conditioning system includes a controller. When the system is in heating mode, the controller controls the first magnet 92 and the second magnet 93 to become electromagnetized, generating an alternating magnetic field by rotating the impeller 9 of the outdoor fan. This magnetic field heats the heating pipe 8, raising the temperature of the refrigerant flowing through it and providing auxiliary heating. When the system is in cooling mode, the controller de-energizes and demagnetizes the first magnet 92 and the second magnet 93 to prevent heating of the heating pipe 8 during cooling. Of course, without departing from the principles of this invention, in other embodiments, those skilled in the art can also use permanent magnets for the first magnet 92 and the second magnet 93.
[0041] Regarding the alternating magnetic field source 7, it should be noted that although the alternating magnetic field source 7 is a magnet in this invention, and an alternating magnetic field is generated by rotating the magnet, this is not a specific limitation of this invention. Without departing from the principle of this invention, in other embodiments, those skilled in the art can also use an electromagnetic coil as the alternating magnetic field source 7 to heat the heating pipe 8.
[0042] In summary, the working principle of this implementation method is as follows:
[0043] After the air conditioning system enters the heating mode, firstly, the compressor 1 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant is liquefied into a medium-temperature, medium-pressure liquid refrigerant through the first heat exchanger 2, and heat is released to the outside. The liquid refrigerant enters the expansion valve 3 for throttling, and then passes through the second heat exchanger 4 to absorb heat, causing the liquid refrigerant to evaporate into a gaseous state. It then enters the compressor 1 again for compression and pressurization. This cycle repeats, using the heat emitted by the first heat exchanger 2 for heating.
[0044] Secondly, the controller controls the first magnet 92 and the second magnet 93 to be energized, and the impeller 9 of the outdoor fan rotates to generate an alternating magnetic field, which heats the heating pipe 8 located in the alternating magnetic field, thereby increasing the temperature of the refrigerant flowing through the heating pipe 8 and achieving auxiliary heating.
[0045] Example 2
[0046] like Figure 3 As shown, this embodiment discloses an air conditioning system, which has a structure that is basically the same as the air conditioning system in Embodiment 1. The difference from Embodiment 1 is that: the refrigerant pipeline includes a main pipeline 10 near the first heat exchanger 2. The main pipeline 10 is located between the first heat exchanger 2 and the compressor 1. The heating pipeline 8 is connected in parallel with the main pipeline 10. The air conditioning system is provided with a first switching valve 6, which is used to control the refrigerant to flow through the heating pipeline 8 or the main pipeline 10.
[0047] When auxiliary heating is activated, an alternating magnetic field source 7 heats the heating pipe 8 to provide auxiliary heating. The first switching valve 6 switches the channel, allowing refrigerant to flow through the heating pipe 8. The alternating magnetic field source 7 heats the heating pipe 8 to increase the temperature of the refrigerant flowing through it, thus achieving auxiliary heating. Since the heating pipe 8 is generally configured as a coil or serpentine pipe with relatively high resistance, when auxiliary heating is not required, specifically in cooling mode or heating mode where only the compressor is used, the first switching valve 6 switches the channel, allowing refrigerant to flow through the main pipe 10. Only the compressor 1 is used for heating or cooling, thereby reducing the resistance of the refrigerant flowing in the refrigerant pipe.
[0048] Specifically, the first switching valve 6 is a two-position three-way directional valve. Of course, without departing from the principle of the present invention, those skilled in the art can also use other types of valves, such as swing valves, in other embodiments, as long as they can switch the flow direction of the refrigerant.
[0049] Example 3
[0050] This embodiment discloses an air conditioning system, which includes a circulation device and a heat pump unit. It is primarily a water-cooled air conditioner, with relatively large power and floor space requirements, and is mostly used in commercial applications. The heat pump unit and circulation device are generally installed outdoors for ease of installation and heat dissipation.
[0051] like Figure 4 As shown, the heat pump unit includes a compressor 1, a first heat exchanger 2, an expansion valve 3, a second heat exchanger 4, and a four-way reversing valve 5. The compressor 1, first heat exchanger 2, expansion valve 3, and second heat exchanger 4 are sequentially connected via pipes, forming a circulation loop filled with refrigerant. The four-way reversing valve 5 is located at the outlet end of the compressor 1 and is used to switch the flow path of the refrigerant flowing from the outlet of the compressor 1. The pipe connecting the compressor 1 and the first heat exchanger 2 is called the refrigerant piping.
[0052] In heating mode, the refrigerant flowing out of the compressor 1 outlet flows sequentially through the four-way reversing valve 5 to the first heat exchanger 2, the expansion valve 3, and the second heat exchanger 4 before returning to the compressor 1. At this time, the compressor 1 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The first heat exchanger 2 liquefies the high-temperature, high-pressure gaseous refrigerant into a medium-temperature, medium-pressure liquid refrigerant and releases heat to the outside. After the liquid refrigerant enters the expansion valve 3 for throttling, it absorbs heat through the second heat exchanger 4, causing the liquid refrigerant to evaporate and form a gaseous state. It then enters the compressor 1 again for compression and pressurization. This cycle repeats continuously, using the heat generated by the first heat exchanger 2 for heating. In cooling mode, the refrigerant flowing out of compressor 1 flows through the second heat exchanger 4, expansion valve 3 and first heat exchanger 2 in sequence after being acted upon by the four-way reversing valve 5. Compressor 1 compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant is liquefied into a medium-temperature, medium-pressure liquid refrigerant through the second heat exchanger 4 and releases heat to the outside. After the liquid refrigerant enters the expansion valve 3 for throttling, it absorbs heat through the first heat exchanger 2, causing the liquid refrigerant to evaporate and form a gaseous state. It then enters the compressor 1 again for compression and pressurization. This cycle repeats continuously, using the first heat exchanger 2 to absorb heat for cooling.
[0053] The circulation device includes heat exchange fins 11, circulation pipes 12, a third heat exchanger 14, and a pumping device 13. The circulation pipes 12, third heat exchanger 14, and pumping device 13 form a circulation loop. The circulation pipes 12 are filled with a heat exchange medium, typically water. The third heat exchanger 14 can exchange heat with the first heat exchanger 2 to change the temperature of the heat exchange medium. The air conditioning system also includes a heat exchange fan and ventilation ducts. Part of the ventilation ducts is located indoors, and the other part is located outdoors. The heat exchange fan is located outdoors and supplies air to the room through the ventilation ducts. The heat exchange fins 11 are finned and are installed inside the ventilation ducts along with the heat exchange fan. When the heat exchange fan is running, it generates flowing air. The air flowing over the heat exchange fins 11 exchanges heat with them, thus changing the temperature of the air flowing over the heat exchange fins 11 and achieving a heating or cooling effect.
[0054] Specifically, the first heat exchanger 2 is provided with fins, and the third heat exchanger 14 contacts the fins of the first heat exchanger 2, enabling the first heat exchanger 2 to exchange heat with the third heat exchanger 14. The heat exchange medium then flows through the third heat exchanger 14 for further heat exchange, thereby changing the temperature of the heat exchange medium. Of course, without changing the principle of the invention, in other embodiments, the first heat exchanger 2 can be placed inside the third heat exchanger 14, and the heat exchange medium flowing through the third heat exchanger 14 can directly contact the surface of the first heat exchanger 2 for heat exchange.
[0055] The air conditioning system also includes an alternating magnetic field source 7 and a heating pipe 8. The alternating magnetic field source 7 generates an alternating magnetic field, and the heating pipe 8 is part of the circulation pipe 12, located within the alternating magnetic field. The heating pipe 8 is a metal pipe, typically copper. Under the electromagnetic induction of the alternating magnetic field, the heating pipe 8 generates an induced current, which is an eddy current. This induced current raises the temperature of the heating pipe 8, thereby increasing the temperature of the heat exchange medium flowing through it. When the auxiliary heating mode is activated, the heat pump unit can increase the temperature of the heat exchange medium flowing through the third heat exchanger 14 through the heat exchange of the second heat exchanger 4. The alternating magnetic field source 7 generates an alternating magnetic field to heat the heat exchange medium flowing through the heating pipe 8. The heated heat exchange medium dissipates heat at the heat exchange fins 11 to achieve heating. The heating power of compressor 1 is between 70% and 85%, while the heating power of alternating magnetic field is over 90%. By using alternating magnetic field to assist in heating the heating pipe 8, the operating power of compressor 1 can be reduced, thereby improving the energy utilization rate of the air conditioning system during the heating process.
[0056] The heating pipe 8 is specifically a coil or a serpentine tube to increase its length within the alternating magnetic field. The longer the heating pipe 8 is within the alternating magnetic field, the greater the induced current generated by the change in the alternating magnetic field within the heating pipe 8, resulting in better heating performance. Insulating sleeves are installed at the ends of the heating pipe 8 to prevent the induced current generated by the heating pipe 8 from being conducted to other components, ensuring that the induced current is fully utilized to raise the temperature of the heating pipe 8 and improve heating efficiency.
[0057] Electrolytes can be added to the heat exchange medium to increase its ionization, so that the heat exchange medium flowing through the heating pipe 8 can also generate induced current under the action of the alternating magnetic field, thereby improving the heating efficiency.
[0058] Since the heating pipe 8 of the water-cooled air conditioning system is relatively large, the alternating magnetic field source 7 can be a separately set rotating disk, driven by a motor to rotate. The first magnet 92 and the second magnet 93 are arranged alternately along the circumference, and an alternating magnetic field is formed after the rotating disk rotates.
[0059] In summary, the working principle of the air conditioning system provided in this embodiment is as follows:
[0060] When the air conditioning system is in heating mode, the second heat exchanger 2 releases heat. The heat exchange medium of the circulating device exchanges heat with the second heat exchanger 2 at the third heat exchanger 14, and then heats up, releasing heat at the heat exchange fins 11 to provide heating. During this period, auxiliary heating can be selectively activated. When auxiliary heating is activated, the alternating magnetic field source 7 generates an alternating magnetic field that can assist in heating the heat exchange medium flowing through the heating pipe 8. When the air conditioning system is in cooling mode, the second heat exchanger 2 absorbs heat. The heat exchange medium of the circulating device exchanges heat with the second heat exchanger 2 at the third heat exchanger 14, and then cools down, absorbing heat from the air flowing through the heat exchange fins 11 to provide cooling.
[0061] Example 4
[0062] like Figure 5 As shown, this embodiment discloses an air conditioning system, which has a structure that is basically the same as the air conditioning system in Embodiment 3. The difference from Embodiment 3 is that: the circulation pipe 12 includes a main pipe 10 near the third heat exchanger 14. The main pipe 10 is specifically located between the third heat exchanger 14 and the heat exchange plate 11. The heating pipe 8 is connected in parallel with the main pipe 10. The air conditioning system is provided with a second switching valve 15, which is used to control the flow of the heat exchange medium through the heating pipe 8 or the main pipe 10.
[0063] When auxiliary heating is activated, an alternating magnetic field source 7 heats the heating pipe 8 to provide auxiliary heating. The second switching valve 15 switches the channel, allowing the heat exchange medium to flow through the heating pipe 8. The alternating magnetic field source 7 heats the heating pipe 8, increasing the temperature of the heat exchange medium flowing through it, thus achieving auxiliary heating. Since the heating pipe 8 is generally configured as a coil or serpentine pipe with relatively high resistance, when auxiliary heating is not required—specifically, in cooling mode or heating mode where only the compressor is used—the second switching valve 15 switches the channel, allowing the heat exchange medium to flow through the main pipe 10, thereby reducing the resistance of the heat exchange medium flowing within the circulation device.
[0064] Specifically, the second switching valve 15 is a two-position three-way directional valve. Of course, without departing from the principle of the present invention, those skilled in the art can also use other types of valves, such as swing valves, in other embodiments, as long as they can switch the flow direction of the heat exchange medium.
[0065] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles 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 such changes or substitutions will all fall within the scope of protection of the present invention.
