Description

Technical Field

[0001] The invention belongs to the field of trigeneration units, in particular to a trigeneration unit. Background Art

[0002] The trigeneration unit used in air conditioning is a device that can provide air conditioning cooling, heating and domestic hot water at the same time. This unit is usually electrically driven, uses a steam compression cycle, and uses air as a heat source to achieve the functions of cooling, heating and supplying domestic hot water. The existing trigeneration unit usually includes an air-conditioning outdoor unit, an air-conditioning indoor unit and a water tank. When the indoor unit is cooling, the waste heat of the outdoor unit is transferred to the water tank to achieve the purpose of supplying domestic hot water.

[0003] In the traditional technical solution, the outdoor unit and the water tank are installed separately, which leads to the waste heat generated by the outdoor unit during operation being easily lost when transferred to the water tank. In the traditional technical solution, when the air-conditioning indoor unit is cooling, the waste heat of the outdoor unit can be recycled to heat the water tank. However, when the air-conditioning indoor unit is heating, it means that the temperature is low.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. A trigeneration unit described in the present invention integrates the condenser pipe and the compressor into the interior of the auxiliary water tank by designing an auxiliary water tank with a fence-type sheet structure. When the compressor inside the outdoor unit is working, the high-temperature and high-pressure gas will flow inside the condenser pipe. The heat released by the condenser pipe will heat the water stored in the auxiliary water tank. That is, when the outdoor unit and the indoor unit of the air conditioner of the device are cooling, the water stored in the auxiliary water tank can be continuously heated. In the device, the water temperature inside the auxiliary water tank can be heated by a heating device inside the auxiliary water tank, such as a heating wire. After the temperature of the auxiliary water tank itself rises, it will affect the condenser pipe and the compressor in its surrounding area, and can quickly increase the heating efficiency of the outdoor unit.

[0018] 2. In the trigeneration unit described in the present invention, when low-temperature and low-pressure gas is input into the air cavity one through the gas transmission pipeline two, the reciprocating piston descends from the highest point of the inner cavity. When the reciprocating piston descends, a suction force is generated, thereby opening the automatic gas valve one, while the automatic gas valve two is always closed. At this time, the air cavity two cannot be connected with the inner cavity through the connecting groove two. With the cooperation of the eccentric rotating structure and the crankshaft connecting rod component, the reciprocating piston rises in the inner cavity, thereby quickly compressing the gas inside the inner cavity, so that the low-temperature and low-pressure gas originally entering the inner cavity is converted into high-temperature and high-pressure gas. When the gas pressure inside the inner cavity is large enough, one end of the bent valve plate two arranged at the bottom of the air cavity two is bent, and the high-temperature and high-pressure gas enters the air cavity two through the connecting groove two, and is then transported to the inside of the condenser pipeline through the gas transmission pipeline one and the connecting pipeline one for refrigeration.

[0019] 3. The trigeneration unit described in the present invention drives the follower piston to rise and fall in the auxiliary chamber when the compound piston is lifted and lowered. At this time, the air pump is in an open state, and the outside air is introduced into the additional air chamber two. Under the same principle as mentioned above, the lifting and lowering of the follower piston compresses the low-temperature and low-pressure gas entering from the four sides of the automatic air valve into high-temperature and high-pressure gas, which enters the additional air chamber one through the automatic air valve three. The high-temperature and high-pressure gas in the additional air chamber one is transmitted to the interior of multiple disc pipes through the water tank connecting pipe, which heats the disc pipes and the auxiliary water tank more quickly, and the water temperature that can be heated will be higher.

DETAILED DESCRIPTION

[0032] 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. Example

[0033] like Figure 1-Figure 3As shown, a trigeneration unit according to an embodiment of the present invention comprises an indoor air-conditioning unit 1 installed indoors and an outdoor unit 2 installed outdoors, wherein a pipe connection assembly 3 is installed inside the outdoor unit 2, the indoor air-conditioning unit 1 and the outdoor unit 2 are connected by a pipe through the pipe connection assembly 3, the pipe connection assembly 3 comprises a pipe joint 31 connected to the indoor air-conditioning unit 1 and a condenser pipe 32 connected to the pipe joint 31, the pipe connection assembly 3 further comprises a compressor 4 installed inside the outdoor unit 2, the compressor 4 completes condensation by connecting to the condenser pipe 32, and the indoor air-conditioning unit 1 and the outdoor unit 2 are connected by a pipe. The outdoor unit 2 includes a base plate 21 and an outer shell frame 22 fixedly installed above the base plate 21, an overhead frame 24 fixedly installed above the outer shell frame 22, a heat dissipation top plate 26 fixedly installed above the overhead frame 24, an outdoor unit fan 25 movably installed at the bottom of the heat dissipation top plate 26, the outdoor unit fan 25 is located directly above the condenser pipe 32, the condenser pipe 32 and the compressor 4 are located inside the auxiliary water tank 23, the auxiliary water tank 23 is a fence-type sheet structure, the bottom of the auxiliary water tank 23 is in contact with the base plate 21, and a heating device is provided inside the auxiliary water tank 23.

[0034] Specifically, the device includes an air-conditioning indoor unit 1, an outdoor unit 2, a pipe connection component 3 and an auxiliary water tank 23. The cooling and heating effects of the device are consistent with the traditional principles. First, the air-conditioning indoor unit 1 is connected to the pipe connection component 3 through a pipe. When the air-conditioning indoor unit 1 is required to cool, the low-temperature and low-pressure gas of the refrigerant inside the air-conditioning indoor unit 1 enters the pipe joint 31 and the condenser pipe 32. After the low-temperature and low-pressure gas enters the compressor 4, the low-temperature and low-pressure gas is converted into high-temperature and high-pressure gas under the action of the compressor 4. That is, at this time, the high-temperature and high-pressure gas flows inside the condenser pipe 32, and the high-temperature and high-pressure gas forms a The large temperature difference is driven by electricity to rotate the outdoor fan 25 for high-speed cooling. The high-temperature gas suddenly loses heat and condenses into liquid. At this time, the liquid refrigerant enters the air-conditioning indoor unit 1, and achieves indoor cooling effect through the original structure inside the air-conditioning indoor unit 1, such as the expansion valve and the evaporator. This process is the basic principle of the existing air-conditioning system. First, in this device, the auxiliary water tank 23 is designed as a fence-type sheet structure, and the condenser pipe 32 and the compressor 4 are integrated into the auxiliary water tank 23. At this time, the outdoor fan 25 can be set as a ceiling fan, so that when the outdoor fan 25 is working, the wind direction is upward, and there is no need to hang it. The wall-type structure is that the auxiliary water tank 23 is integrated into the interior of the outdoor unit 2 in the device. When the compressor 4 in the outdoor unit 2 is working, the high-temperature and high-pressure gas will flow in the condenser pipe 32. That is, the temperature of the condenser pipe 32 is relatively high at this time, and the auxiliary water tank 23 is arranged around the outside of the condenser pipe 32. Therefore, the heat released by the condenser pipe 32 will have a heating effect on the water stored in the auxiliary water tank 23. That is, when the outdoor unit 2 and the air-conditioning indoor unit 1 of the device are cooling, the water stored in the auxiliary water tank 23 can be continuously heated. The heated water plays the role of domestic hot water. Because the essence of air conditioning is the transport of hot and cold gases Operation and exchange require that when the traditional air-conditioning system is heating, the temperature difference between the outdoor and indoor is not large, so the heating rate of the air conditioner will be slow. In the present device, the auxiliary water tank 23 can be heated by an internal heating device, such as a heating wire, to heat the internal water temperature of the auxiliary water tank 23. After the auxiliary water tank 23 itself is heated, it will affect the condenser pipe 32 and the compressor 4 within its surrounding area, which can quickly increase the heating efficiency of the outdoor unit 2. In a cold air environment, the water temperature of the auxiliary water tank 23 will first thaw the condenser pipe 32 and the compressor 4, so that the condenser pipe 32 and the compressor 4 will not work immediately in a quick-freezing environment, thereby effectively extending the service life of the outdoor unit 2.

[0035] like Figure 5As shown, the outer shell frame 22 includes a plurality of hollow plates 221 and heat dissipation arc plates 222 located outside the auxiliary water tank 23, the plurality of hollow plates 221 and heat dissipation arc plates 222 surround the outside of the auxiliary water tank 23, and adjacent hollow plates 221 and heat dissipation arc plates 222 are connected, the upper ends of the plurality of hollow plates 221 and heat dissipation arc plates 222 are connected to the overhead frame 24, and the lower ends of the plurality of hollow plates 221 and heat dissipation arc plates 222 are connected to the bottom plate 21.

[0036] Specifically, the surrounding design of the auxiliary water tank 23 will allow the high temperature and high pressure inside the condenser pipe 32 to heat the stored water inside the auxiliary water tank 23 through waste heat, and a plurality of hollow plates 221 and heat dissipation arc plates 222 are arranged on the outside of the auxiliary water tank 23, and there will be a certain distance between the plurality of hollow plates 221 and the heat dissipation arc plates 222, and the plurality of hollow plates 221 and the heat dissipation arc plates 222 and the auxiliary water tank 23 are all connected to the bottom plate 21 at the bottom, and under the action of the outdoor fan 25, the inside of the auxiliary water tank 23 and the distance between the auxiliary water tank 23 and the plurality of hollow plates 221 and the heat dissipation arc plates 222 can be acted on, thereby expanding the working efficiency of the outdoor fan 25 in the outdoor unit 2.

[0037] like Figure 4 and Figure 6 As shown, a support panel 27 is installed inside the outer shell frame 22, and the two sides of the support panel 27 are connected to two adjacent hollow plates 221. The support panel 27 is used to support the pipe joint 31. The support panel 27 is fixedly installed with a finned heat sink 28 on the side facing the condenser pipe 32. A plurality of disc pipes 231 are installed inside the auxiliary water tank 23, and the plurality of disc pipes 231 are interconnected. The disc pipes 231 arranged at the bottom of the auxiliary water tank 23 are installed with a water valve.

[0038] Specifically, the finned heat sink 28 is arranged toward the inside of the auxiliary water tank 23. The finned heat sink 28 increases the surface area in contact with the air through its special shape and structure, thereby improving the efficiency of heat exchange. During the air-conditioning refrigeration process, the finned heat sink 28 in the outdoor unit 2 dissipates the heat in the high-temperature and high-pressure refrigerant gas compressed by the compressor 4 to the external environment, so that the refrigerant condenses into a high-pressure liquid. In the heating mode, the finned heat sink 28 helps to prevent the water generated during the defrosting of the outdoor unit 2 from flowing down smoothly and accumulating, thereby avoiding ice from forming in the place where the water accumulates when the outdoor unit 2 is started again in the heating mode, thereby affecting the heating effect. A plurality of disc pipes 231 are arranged inside the auxiliary water tank 23. In the heating state of the device, only the water stored in the temporal part of the plurality of disc pipes 231 in the space of the auxiliary water tank 23 is heated, which can quickly increase the temperature of the auxiliary water tank 23 itself, thereby affecting the condenser pipe 32 and the compressor 4.

[0039] like Figure 7As shown, the bottom of the compressor 4 is connected to the base plate 21 , and a connecting pipe 1 41 and a connecting pipe 2 42 are fixedly installed on the top of the compressor 4 . The compressor 4 is connected to the condenser pipe 32 through the connecting pipe 1 41 and the connecting pipe 2 42 .

[0040] Specifically, when the device is cooling, the low-temperature and low-pressure refrigerant gas inside the air-conditioning indoor unit 1 enters into the connecting pipe 2 42 through the connection of the pipe connecting assembly 3, and then enters into the compressor 4. Through the compression work of the compressor 4, the low-temperature and low-pressure refrigerant gas is compressed into a high-temperature and high-pressure gas. This gas is transported through the connecting pipe 1 41 and flows inside the condenser pipe 32 for subsequent effects.

[0041] like Figure 8-Figure 9 As shown, an inner core 5 and a top air outlet block 6 are fixedly installed inside the compressor 4. The top air outlet block 6 is located directly above the inner core 5. An inner cavity 54 is opened inside the inner core 5. An eccentric rotating structure 51 is movably installed at the inner bottom of the inner cavity 54. The eccentric rotating structure 51 is driven by a motor. A crankshaft connecting rod member 52 is movably installed on the side of the eccentric rotating structure 51. A reciprocating piston 53 is slidably installed inside the inner cavity 54. The eccentric rotating structure 51 is connected to the reciprocating piston 53 through the crankshaft connecting rod member 52.

[0042] An air cavity 1 61 and an air cavity 2 63 are provided at the inner bottom of the top air outlet block 6, an automatic air valve 1 62 is installed at the inner bottom of the air cavity 1 61, an automatic air valve 2 64 is installed at the inner bottom of the air cavity 2 63, the air cavity 1 61 is connected with the inner cavity 54 through the automatic air valve 1 62, the air cavity 2 63 is connected with the inner cavity 54 through the automatic air valve 2 64, a gas delivery pipeline 1 411 is installed at the bottom of the connecting pipeline 1 41, one end of the gas delivery pipeline 1 411 is connected with the air cavity 2 63, a gas delivery pipeline 2 421 is installed at the bottom of the connecting pipeline 2 42, one end of the gas delivery pipeline 2 421 is connected with the air cavity 1 61.

[0043] The automatic air valve 62 includes a plurality of connecting grooves 621 extending through the bottom of the air cavity 61 and a curved valve piece 622 movably mounted on the top of the inner cavity 54, wherein the curved end of the curved valve piece 622 covers the plurality of connecting grooves 621. The automatic air valve 64 includes a plurality of connecting grooves 641 extending through the bottom of the air cavity 63 and a curved valve piece 642 movably mounted on the bottom of the air cavity 63, wherein the curved end of the curved valve piece 642 covers the plurality of connecting grooves 641.

[0044] Specifically, when the low-temperature and low-pressure gas is transported from the connecting pipe 42, it will enter the interior of the air cavity 61 through the gas delivery pipe 421. At this time, the eccentric rotating structure 51 is driven by the motor to rotate, and the reciprocating piston 53 is driven to rise and fall in the inner cavity 54 under the action of the crankshaft connecting rod member 52. When the device is refrigerating and the gas delivery pipe 421 inputs low-temperature and low-pressure gas into the air cavity 61, the reciprocating piston 53 descends from the highest point of the inner cavity 54 under the action of the crankshaft connecting rod member 52 and the eccentric rotating structure 51. When the reciprocating piston 53 descends, a suction force is generated, thereby opening the automatic gas valve 62, while the automatic gas valve 64 is always closed, which is specifically manifested in that the bent valve plate 622 bends toward the end of the connecting groove 621, so that the air cavity 61 passes through multiple A connecting groove 1 621 is connected to the automatic air valve 2 64, while the bent valve plate 2 642 is not bent and is always in a straight state. At this time, the air cavity 2 63 cannot be connected with the interior of the inner cavity 54 through the connecting groove 2 641. With the cooperation of the eccentric rotating structure 51 and the crankshaft connecting rod member 52, the reciprocating piston 53 rises in the inner cavity 54, and then quickly compresses the gas inside the inner cavity 54, so that the low-temperature and low-pressure gas originally entering the inner cavity 54 is converted into high-temperature and high-pressure gas. When the gas pressure inside the inner cavity 54 is large enough, one end of the bent valve plate 2 642 arranged at the bottom of the air cavity 2 63 is bent, and the high-temperature and high-pressure gas enters the air cavity 2 63 through the connecting groove 2 641, and then is transported to the inside of the condenser pipe 32 for refrigeration through the gas transmission pipe 1 411 and the connecting pipe 1 41. Example

[0045] like Figure 9-10 As shown, compared with Example 1, another embodiment of the present invention is: an additional air chamber 2 69 and an additional air chamber 1 68 are provided at the inner top of the top air outlet block 6, an automatic air valve 4 691 is installed at the inner bottom of the additional air chamber 2 69, and an automatic air valve 3 681 is installed at the inner bottom of the additional air chamber 1 68. The automatic air valve 4 691 and the automatic air valve 1 62 are components made of the same structure, and the automatic air valve 3 681 and the automatic air valve 2 64 are components made of the same structure. An auxiliary chamber 7 is also provided inside the top air outlet block 6, and a follower piston 71 is slidably installed inside the auxiliary chamber 7. A lifting column 73 is fixedly installed at the bottom of the follower piston 71, and one end of the lifting column 73 is located inside the inner cavity 54. A lifting groove 72 is provided at the bottom of the auxiliary cavity 7, and the lifting groove 72 is connected to the inner cavity 54. The lifting column 73 is slidably installed inside the lifting groove 72, and a return spring 74 is installed at the inner bottom of the auxiliary cavity 7, and the upper end of the return spring 74 is connected to the bottom side of the follower piston 71.

[0046] Two solenoid valve pipes 66, an air pump 65 and a water tank connecting pipe 67 are installed at the upper end of the top air outlet block 6. The two solenoid valve pipes 66 are respectively connected to the additional air chamber 2 69 and the additional air chamber 1 68. The air pump 65 is connected to the additional air chamber 2 69 through a pipe. The air pump 65 is located on the outside of the compressor 4. The lower end of the water tank connecting pipe 67 is connected to the additional air chamber 1 68. One end of the water tank connecting pipe 67 is connected to the corresponding disc pipe 231. The additional air chamber 2 69 is connected to the auxiliary chamber 7 through the automatic air valve 4 691, and the additional air chamber 1 68 is connected to the auxiliary chamber 7 through the automatic air valve 3 681.

[0047] Specifically, when the device is performing refrigeration, the reciprocating piston 53 inside the inner cavity 54 will continuously rise and fall to compress the gas entering the air cavity 1 61 into high-temperature and high-pressure gas and transport it out through the air cavity 2 63. In the device, when the reciprocating piston 53 rises at the top of the inner cavity 54 to the limit position, it will contact the lifting column 73, thereby driving the lifting column 73 and the follower piston 71 to rise a certain distance from the initial position inside the auxiliary cavity 7. At this time, the return spring 74 is stretched. After the reciprocating piston 53 drops, under the action of the restoring force of the return spring 74, the follower piston 71 will drop to the initial position inside the auxiliary cavity 7, that is, when the reciprocating piston 53 is lifted and lowered, it will drive the follower piston 71 to rise and lower in the auxiliary cavity 7. At this time, the air pump 65 is in an open state, and the outside air is introduced into the additional air chamber 2 69. Under the same principle as mentioned above, the rise and fall of the follower piston 71 will release the low-temperature and low-pressure gas entering the automatic air valve 4 691. The body is compressed into high temperature and high pressure and enters the additional air chamber 1 68 through the automatic air valve 3 681. The high temperature and high pressure gas inside the additional air chamber 1 68 is transmitted to the inside of the multiple disc pipes 231 through the water tank connecting pipe 67, which heats the disc pipe 231 and the auxiliary water tank 23 more quickly, and the water temperature that can be heated will be higher. When the amount of water stored in the disc pipe 231 is large, the water can be discharged through the water valve at the bottom. During this process, the air valves of the two solenoid valve pipes 66 are closed. When the device is heating, the reciprocating piston 53 still drives the follower piston 71 to rise and fall, but at this time there is no need to heat the auxiliary water tank 23, so the air pump 65 is turned off and the two solenoid valve pipes 66 are opened. At this time, the additional air chamber 2 69 and the additional air chamber 1 68 are connected to the outside world, and the rise and fall of the follower piston 71 will continuously replace the air in the additional air chamber 1 68 and the additional air chamber 2 69, thereby enhancing the air circulation of the outdoor unit 2.

[0048] Working principle: The device includes an air-conditioning indoor unit 1, an outdoor unit 2, a pipe connection component 3 and an auxiliary water tank 23. The cooling and heating effects of the device are consistent with the traditional principles. First, the air-conditioning indoor unit 1 is connected to the pipe connection component 3 through a pipe. When the air-conditioning indoor unit 1 is required to cool, the low-temperature and low-pressure gas of the refrigerant inside the air-conditioning indoor unit 1 enters the pipe joint 31 and the condenser pipe 32. After the low-temperature and low-pressure gas enters the compressor 4, the low-temperature and low-pressure gas is converted into high-temperature and high-pressure gas under the action of the compressor 4. That is, at this time, the high-temperature and high-pressure gas flows inside the condenser pipe 32, and the high-temperature and high-pressure gas forms a The outdoor fan 25 is driven by electricity to rotate and cool down at a high speed. The high-temperature gas suddenly loses heat and condenses into liquid. At this time, the liquid refrigerant enters the air-conditioning indoor unit 1, and achieves indoor cooling effect through the original structure inside the air-conditioning indoor unit 1, such as the expansion valve and the evaporator. This process is the basic principle of the existing air-conditioning system. First, in this device, the condenser pipe 32 and the compressor 4 are integrated into the auxiliary water tank 23 through the auxiliary water tank 23 designed as a fence-type sheet structure. At this time, the outdoor fan 25 can be set as a ceiling fan, so that when the outdoor fan 25 is working, the wind direction is upward, and there is no need to hang it. The wall-type structure is that the auxiliary water tank 23 is integrated into the interior of the outdoor unit 2 in the device. When the compressor 4 in the outdoor unit 2 is working, the high-temperature and high-pressure gas will flow in the condenser pipe 32. That is, the temperature of the condenser pipe 32 is relatively high at this time, and the auxiliary water tank 23 is arranged around the outside of the condenser pipe 32. Therefore, the heat released by the condenser pipe 32 will have a heating effect on the water stored in the auxiliary water tank 23. That is, when the outdoor unit 2 and the air-conditioning indoor unit 1 of the device are cooling, the water stored in the auxiliary water tank 23 can be continuously heated. The heated water plays the role of domestic hot water. Because the essence of air conditioning is the transport of hot and cold gases Operation and exchange require that when the traditional air-conditioning system is heating, the temperature difference between the outdoor and indoor is not large, so the heating rate of the air conditioner will be slow. In the present device, the auxiliary water tank 23 can be heated by an internal heating device, such as a heating wire, to heat the internal water temperature of the auxiliary water tank 23. After the auxiliary water tank 23 itself is heated, it will affect the condenser pipe 32 and the compressor 4 within its surrounding area, which can quickly increase the heating efficiency of the outdoor unit 2. In a cold air environment, the water temperature of the auxiliary water tank 23 will first thaw the condenser pipe 32 and the compressor 4, so that the condenser pipe 32 and the compressor 4 will not work immediately in a quick-freezing environment, thereby effectively extending the service life of the outdoor unit 2.

[0049] When the device is performing refrigeration, the reciprocating piston 53 inside the inner cavity 54 will continuously rise and fall to compress the gas entering the air cavity 1 61 into high-temperature and high-pressure gas and transport it out through the air cavity 2 63. In the device, when the reciprocating piston 53 rises at the top of the inner cavity 54 to the limit position, it will contact the lifting column 73, thereby driving the lifting column 73 and the follower piston 71 to rise a certain distance from the initial position inside the auxiliary cavity 7. At this time, the return spring 74 is stretched. After the reciprocating piston 53 drops, under the action of the restoring force of the return spring 74, the follower piston 71 will drop to the initial position inside the auxiliary cavity 7, that is, when the reciprocating piston 53 is lifted and lowered, it will drive the follower piston 71 to lift and lower in the auxiliary cavity 7. At this time, the air pump 65 is in an open state, and the outside air is introduced into the additional air chamber 2 69. Under the same principle as mentioned above, the rise and fall of the follower piston 71 compresses the low-temperature and low-pressure gas entering the automatic air valve 4 691. The high-temperature and high-pressure gas is compressed into high temperature and high pressure and enters the additional air chamber 1 68 through the automatic air valve 3 681. The high-temperature and high-pressure gas inside the additional air chamber 1 68 is transmitted to the inside of multiple disc pipes 231 through the water tank connecting pipe 67, which heats the disc pipe 231 and the auxiliary water tank 23 more quickly, and the water temperature that can be heated will be higher. When the amount of water stored in the disc pipe 231 is large, the water can be discharged through the water valve at the bottom. During this process, the air valves of the two solenoid valve pipes 66 are closed. When the device is heating, the reciprocating piston 53 still drives the follower piston 71 to rise and fall, but at this time there is no need to heat the auxiliary water tank 23, so the air pump 65 is turned off and the two solenoid valve pipes 66 are opened. At this time, the additional air chamber 2 69 and the additional air chamber 1 68 are connected to the outside world, and the rise and fall of the follower piston 71 will continuously replace the air in the additional air chamber 1 68 and the additional air chamber 2 69, thereby enhancing the air circulation of the outdoor unit 2.
