Description

Technical Field

[0001] This invention relates to the technical field of heat pump equipment, and more specifically, to a heat source tower heat pump system and an air conditioner. Background Technology

[0002] In the context of energy conservation and emission reduction, the heating sector is increasingly adopting heat pumps for heating, with air-cooled heat pumps being the mainstream method. Air-cooled heat pumps can operate year-round, providing cooling in summer and heating in winter. However, their cooling efficiency ratio is low in summer, and defrosting issues occur in winter, resulting in a less than ideal overall energy efficiency ratio. While cooling tower water-cooled systems offer higher cooling efficiency ratios in summer, they are unusable in winter, limiting equipment availability. Furthermore, separately installed winter heating equipment increases initial investment.

[0003] To address the issues of low energy efficiency ratios in air-cooled heat pumps and the inability of water-cooled cooling tower systems to function in winter, heat source tower heat pump systems have been proposed. These systems function as water-cooled cooling tower systems in summer, offering high cooling efficiency. In winter, by replacing the cooling water with antifreeze, they achieve low-temperature heat extraction without frosting or defrosting problems, maintaining a high energy efficiency ratio even in winter. This dual-purpose system allows for efficient year-round operation, saving on operating costs and reducing carbon emissions.

[0004] Although heat source towers do not have frost problems, the antifreeze in them absorbs moisture from the air after heat exchange, causing the solution concentration to become increasingly dilute, raising the freezing point, and increasing the risk of freezing. The antifreeze needs to be regenerated and concentrated before it can be reused. Solution regeneration generally requires additional energy, resulting in high regeneration costs, increasing operating costs, and reducing the heating output cost (COP).

[0005] As can be seen from the above, the current heat source tower has the problem of poor efficiency due to the risk of icing. Summary of the Invention

[0032] Example 1

[0033] To address the problem of poor efficiency caused by the risk of icing in existing heat source towers, this embodiment provides a heat source tower heat pump system located inside an air conditioner.

[0034] like Figure 1As shown, the heat source tower heat pump system includes a heat source tower 1, a regeneration assembly, a heat source heat pump system 3, a regeneration heat pump system 4, a first pipeline 36, and a second pipeline 211. The heat source tower 1 has a heat source storage liquid area 13. The regeneration assembly includes a regeneration storage liquid tank 23, a regeneration tower 2, and a circulating air duct assembly. The regeneration storage liquid tank 23 is connected to the regeneration tower 2, and the circulating air duct assembly is located inside the regeneration tower 2. The heat source heat pump system 3 includes a first heat exchanger 32 and a second heat exchanger 34, and the regeneration heat pump system 4 includes a third heat exchanger 44 and a fourth heat exchanger 42. The heat source storage liquid... Zone 13 is connected to the regeneration storage tank 23, the first heat exchanger 32, and the third heat exchanger 44 in a switchable manner. The outlets of the first heat exchanger 32 and the third heat exchanger 44 are connected to the heat source tower 1. The regeneration storage tank 23, the fourth heat exchanger 42, and the regeneration tower 2 are connected in sequence. The second heat exchanger 34 and the third heat exchanger 44 are installed on the first pipeline 36 to heat or cool the liquid inside the first pipeline 36. At least a part of the circulating air duct assembly is installed on the second pipeline 211 to heat the liquid inside the second pipeline 211.

[0035] Specifically, the heat source tower heat pump system of this application employs a combination of heat source tower 1, regeneration components, heat source heat pump system 3, and regeneration heat pump system 4 to achieve heat recycling, avoid heat loss, and prevent solution freezing during heat recycling, significantly reducing regeneration costs and improving the heating efficiency ratio of heat source tower 1. Simultaneously, the avoidance of heat loss also significantly improves the heating efficiency of the heat source tower heat pump system of this application, resulting in high heating efficiency of the liquid inside the first pipe 36 and the second pipe 211. The heat source tower heat pump system of this application can both heat and cool the liquid inside the pipes, making it suitable for different seasons and allowing year-round operation, greatly improving equipment utilization.

[0036] It should be noted that the first heat exchanger 32, the second heat exchanger 34, the third heat exchanger 44 and the fourth heat exchanger 42 are used to exchange heat with the liquid inside the pipeline, so as to heat the liquid inside the pipeline or absorb the temperature of the liquid inside the pipeline, so as to heat or cool the liquid inside the pipeline.

[0037] Furthermore, the heat source tower 1 has a heat source accommodating cavity 10 and a heat source tower 1 liquid inlet and a heat source tower 1 liquid outlet connected to the heat source accommodating cavity 10. Along the height direction of the heat source tower 1, the heat source tower 1 liquid inlet is located above the heat source tower 1 liquid outlet, and the heat source liquid outlet is connected to the heat source liquid storage area 13 for outputting liquid to the outside.

[0038] Furthermore, the heat source tower heat pump system also includes a liquid level balance pipe 113, which is installed between the heat source liquid storage area 13 and the regeneration liquid storage tank 23. By installing the liquid level balance pipe 113, a dynamic balance is achieved between the liquid in the regeneration liquid storage tank 23 and the heat source liquid storage area 13, preventing freezing.

[0039] Furthermore, the heat source tower heat pump system also includes a first liquid outlet pipe 15, a first circulation pipe 114, a second circulation pipe 115, and a connecting pipe 17. The first end of the first liquid outlet pipe 15 is connected to the heat source storage area 13 through the liquid outlet of the heat source tower 1. One end of the first circulation pipe 114 is connected to the second end of the first liquid outlet pipe 15, and the other end of the first circulation pipe 114 is connected to the liquid inlet of the heat source tower 1. A first heat exchanger 32 is installed on the first circulation pipe 114 to heat or cool the liquid inside the first circulation pipe 114. One end of the second circulation pipe 115 is connected to the second end of the first liquid outlet pipe 15, and the other end of the second circulation pipe 115 is connected to the liquid inlet of the heat source tower 1. A third heat exchanger 44 is installed on the second circulation pipe 115 to cool the liquid inside the second circulation pipe 115. One end of the connecting pipe 17 is connected to the second end of the first liquid outlet pipe 15, and the other end of the connecting pipe 17 is connected to the regeneration storage tank 23. The liquid inside the heat source storage area 13 enters the first outlet pipe 15 through the outlet of the heat source tower 1, and the liquid inside the first outlet pipe 15 supplies liquid to the first circulation pipe 114, the second circulation pipe 115 and the connecting pipe 17 respectively.

[0040] The first outlet pipe 15, the first circulation pipe 114, and the heat source tower 1 form a first circulation loop, so that the liquid inside the first circulation pipe 114 is heated or cooled and then flows back, thereby forming a liquid circulation flow. The first outlet pipe 15, the second circulation pipe 115, and the heat source tower 1 form a second circulation loop, so that the liquid inside the second circulation pipe 115 is cooled and then flows back, thereby forming a liquid circulation flow. The liquid inside the second circulation pipe 115 is different from the liquid inside the first circulation pipe 114, and the liquid inside the second circulation pipe 115 is only used for cooling.

[0041] In this embodiment, the heat source tower heat pump system further includes a heat source pump 16, a first valve body 112, a second valve body 111, and a third valve body 18. The heat source pump 16 is disposed on the first liquid outlet pipe 15, the first valve body 112 is disposed on the second circulation pipe 115 and located between the heat source pump 16 and the third heat exchanger 44, the second valve body 111 is disposed on the second circulation pipe 115 and located between the third heat exchanger 44 and the heat source tower 1, and the third valve body 18 is disposed on the connecting pipe 17.

[0042] Among them, the heat source pump 16 provides driving force for the liquid flow direction, the first valve body 112 and the second valve body 111 control the opening and closing of the second circulation pipe 115 and are located on both sides of the third heat exchanger 44 respectively, and the third valve body 18 is installed on the connecting pipe 17 to control the opening and closing of the connecting pipe 17, thereby realizing the control of whether to supply liquid to the interior of the regeneration storage tank 23.

[0043] Furthermore, the regenerative heat pump system 4 includes a regenerative compressor 41, a fourth heat exchanger 42, a regenerative expansion valve 43, and a third heat exchanger 44 connected in sequence. The third heat exchanger 44 is an evaporator, and the fourth heat exchanger 42 is a condenser.

[0044] like Figure 1 As shown, the heat source heat pump system 3 also includes a heat source compressor 31, a four-way valve 35, and a heat source expansion valve 33. The four-way valve 35 is located at the output end of the heat source compressor 31. The heat source compressor 31 is connected to the first heat exchanger 32 and the second heat exchanger 34 through the four-way valve 35. The heat source expansion valve 33 is located on the side of the first heat exchanger 32 and the second heat exchanger 34 away from the heat source compressor 31. The heat source compressor 31, the four-way valve 35, the first heat exchanger 32, the heat source expansion valve 33, and the second heat exchanger 34 are connected to form a closed-loop circulation system.

[0045] Specifically, the heat source heat pump system 3 has a cooling mode and a heating mode. When the heat source heat pump system 3 is in heating mode, the heat source compressor 31 provides driving force for the refrigerant to flow sequentially through the four-way valve 35, the second heat exchanger 34, the heat source expansion valve 33, the first heat exchanger 32, and the four-way valve 35 before flowing back to the heat source compressor 31. The first heat exchanger 32 is an evaporator used to cool the liquid inside the first circulation pipe 114, and the second heat exchanger 34 is a condenser used to heat the liquid inside the first pipe 36. When the heat source heat pump system 3 is in cooling mode, the heat source compressor 31 provides driving force for the refrigerant to flow sequentially through the four-way valve 35, the first heat exchanger 32, the heat source expansion valve 33, the second heat exchanger 34, and the four-way valve 35 before flowing back to the heat source compressor 31. The first heat exchanger 32 is a condenser used to heat the liquid inside the first circulation pipe 114, and the second heat exchanger 34 is an evaporator used to cool the liquid inside the first pipe 36.

[0046] The cooling and heating modes of the heat pump system 3 are relative to the first pipeline 36. The flow of refrigerant in the compressor is controlled by the four-way valve 35, thereby realizing the heat exchange state of the first heat exchanger 32 and the second heat exchanger 34. That is, by controlling the four-way valve 35, the first heat exchanger 32 can be the evaporator and the second heat exchanger 34 can be the condenser in the heating mode; and the first heat exchanger 32 can be the condenser and the second heat exchanger 34 can be the evaporator in the cooling mode.

[0047] Furthermore, the heat source compressor 31 provides driving force for the refrigerant flow, and the heat source expansion valve 33 throttles the cooled refrigerant to become a low-temperature refrigerant, so that the low-temperature refrigerant can be used to exchange heat with the liquid inside the pipeline.

[0048] In this embodiment, the heat source heat pump system 3 can switch modes to be suitable for outputting low-temperature or high-temperature solutions inside the first pipe 36. One system realizes two output requirements. In this application, while the heat is circulated through the circulation pipe, it can realize two requirements: heating or cooling the liquid inside the first pipe 36, thus improving applicability.

[0049] like Figure 1 As shown, the liquid inlet of the first pipe 36 is located between the liquid inlet of the second heat exchanger 34 and the liquid inlet of the third heat exchanger 44, and the liquid outlet of the first pipe 36 is located between the liquid outlet of the second heat exchanger 34 and the liquid outlet of the third heat exchanger 44.

[0050] The first pipeline 36 is located between the liquid inlet end of the second heat exchanger 34 and the liquid inlet end of the third heat exchanger 44, and between the liquid outlet end of the second heat exchanger 34 and the liquid outlet end of the third heat exchanger 44.

[0051] The heat pump system of the heat source tower also includes a fourth valve body 19 and a fifth valve body 110. The fourth valve body 19 is located at the liquid inlet end of the third heat exchanger 44, and the fifth valve body 110 is located at the liquid outlet end of the third heat exchanger 44.

[0052] Specifically, the flow path of the liquid inside the first pipe 36 is controlled by controlling the opening and closing of the fourth valve body 19 and the fifth valve body 110. When the fourth valve body 19 and the fifth valve body 110 are open, the liquid entering the inlet end of the first pipe 36 flows to the second heat exchanger 34 and the third heat exchanger 44 respectively and then flows out through the outlet end of the first pipe 36. When the fourth valve body 19 and the fifth valve body 110 are closed, the liquid entering the inlet end of the first pipe 36 flows out through the outlet end of the first pipe 36.

[0053] It should be noted that since the third heat exchanger 44 is used to cool the liquid inside the first pipe 36, the fourth valve body 19 and the fifth valve body 110 are only opened when it is necessary to produce a low-temperature solution. The liquid entering from the inlet end of the first pipe 36 can always flow through the second heat exchanger 34 and then out through the outlet end of the first pipe 36. The temperature of the solution flowing through the second heat exchanger 34 is controlled by adjusting the four-way valve 35.

[0054] In this embodiment, the first valve body 112, the second valve body 111, the third valve body 18, the fourth valve body 19, and the fifth valve body 110 are all manual valves.

[0055] like Figure 1As shown, the regeneration tower 2 has a regeneration packing zone 22 and a packing inlet and a packing outlet connected to the regeneration packing zone 22. The packing inlet is located above the packing outlet, and the packing outlet is connected to the regeneration storage tank 23.

[0056] The regeneration packing zone 22 is located inside the regeneration containment chamber 20 of the regeneration tower 2. The regeneration packing zone 22 and the regeneration storage tank 23 form a closed-loop circulation system. The regeneration components include a third pipeline 25 and a regeneration pump 24. One end of the third pipeline 25 is connected to the regeneration storage tank 23, and the other end of the third pipeline 25 is connected to the packing inlet. A fourth heat exchanger 42 is installed on the third pipeline 25 to heat the liquid inside the third pipeline 25. The regeneration pump 24 is installed on the third pipeline 25 to provide driving force for the flow of liquid inside the third pipeline 25.

[0057] Specifically, the fourth heat exchanger 42 is used to heat the liquid inside the third pipeline 25, so that the liquid flowing through the fourth heat exchanger 42 is heated and then flows to the regeneration packing zone 22 to heat the gas flowing through the regeneration packing zone 22, thereby transferring heat to the gas. The cooled liquid flows back to the interior of the regeneration storage tank 23.

[0058] Furthermore, the bottom region of the regenerated packing zone 22 has a slow-flow zone. Through the slow-flow effect of the slow-flow zone, the liquid inside the regenerated packing zone 22 can flow smoothly into the regenerated storage tank 23, and the low-temperature liquid after heat exchange with the circulating gas flows into the regenerated storage tank 23.

[0059] Furthermore, the regeneration assembly also includes a regeneration spray head, which is positioned above the regeneration packing area 22 and is connected to the packing inlet. The regeneration spray head sprays liquid onto the regeneration packing area 22.

[0060] In this embodiment, the regenerated packing zone 22 is filled with packing so that when the regenerated spray head sprays the packing, the circulating gas flowing through the regenerated packing zone 22 can increase the contact area with the sprayed liquid, thereby increasing the heat exchange efficiency. The heated circulating gas flows out of the regenerated packing zone 22 and enters the interior of the circulating air duct 212.

[0061] like Figure 1 As shown, the regeneration tower 2 has a regeneration accommodating cavity 20 and a regeneration air inlet and a regeneration air outlet connected to the regeneration accommodating cavity 20. The regeneration accommodating cavity 20 has a regeneration packing area 22 inside, and the circulating air duct assembly is arranged inside the regeneration accommodating cavity 20.

[0062] The regeneration air inlet is located above the regeneration air outlet.

[0063] Furthermore, the heat source tower heat pump system also includes an air inlet control valve 28 and an air outlet control valve 29. The air inlet control valve 28 is located at the regeneration air inlet, and the air outlet control valve 29 is located at the regeneration air outlet.

[0064] Specifically, by controlling the inlet control valve 28 and the outlet control valve 29, it is possible to determine whether the gas inside the regeneration chamber 20 is connected to the outside of the regeneration tower 2.

[0065] In this embodiment, a set of opposing sidewalls of the regenerated packing zone 22 have air vents that are connected to the circulating air duct assembly, allowing the circulating gas from the circulating air duct assembly to flow through the regenerated packing zone 22. The air vents enable the circulation of circulating gas within the regenerated packing zone 22.

[0066] like Figure 1 As shown, the circulating air duct assembly includes a circulating fan 21, a circulating air duct 212, a circulating air valve 27, and a regenerating surface cooler 26. The circulating fan 21 is connected to the circulating air duct 212, and the circulating air duct 212 is connected to the air outlet. The circulating air valve 27 is installed on the circulating air duct 212. At least a portion of the regenerating surface cooler 26 is located inside the circulating air duct 212. The regenerating surface cooler 26 is installed on the second pipe 211 to heat the liquid inside the second pipe 211. A water receiving tray 213 is installed below the regenerating surface cooler 26 and is used to receive the condensate from the regenerating surface cooler 26.

[0067] Specifically, the circulating fan 21 provides driving force for the flow of circulating gas, and the circulating air valve 27 controls the opening and closing of the circulating air duct 212, thereby controlling whether the circulating gas flows.

[0068] When the circulating gas flows through the regeneration packing zone 22, it exchanges heat with the liquid inside the regeneration packing zone 22. The heated circulating gas flows to the regeneration surface cooler 26 and exchanges heat with the regeneration surface cooler 26 to heat the liquid inside the second pipeline 211. At the same time, the regeneration surface cooler 26 will condense water, which is received by the water receiving pan 213 and discharged through the discharge pipeline 210.

[0069] like Figure 1 As shown, the heat source tower 1 has a heat source accommodating cavity 10 and a heat source tower 1 inlet and a heat source tower 1 outlet connected to the heat source accommodating cavity 10. Along the height direction of the heat source tower 1, the bottom area of ​​the heat source accommodating cavity 10 is a heat source storage area 13. The heat source tower 1 outlet is connected to the heat source storage area 13. The heat source tower 1 inlet is located above the heat source tower 1 outlet. The heat source accommodating cavity 10 also has a heat source packing area 12 located above the heat source storage area 13. The heat source packing area 12 is located in the area between the heat source tower 1 inlet and the heat source tower 1 outlet.

[0070] The heat source packing zone 12 is located between the liquid inlet and the liquid outlet of the heat source tower 1, so that the liquid flowing from the liquid inlet to the liquid outlet of the heat source tower 1 flows through the heat source packing zone 12.

[0071] Furthermore, the heat source tower 1 is provided with a heat source air inlet 116 and a heat source air outlet 117 that are connected to the heat source accommodating cavity 10. The heat source air inlet 116 is located between the heat source liquid storage area 13 and the heat source packing area 12, and the heat source air outlet 117 is located above the heat source packing area 12. The outside gas enters the interior of the heat source accommodating cavity 10 through the heat source air inlet 116, passes through the heat source packing area 12, and then flows out through the heat source air outlet 117.

[0072] Furthermore, to improve the efficiency of gas flow, the heat pump system of the heat source tower also includes an exhaust fan 14, which is installed inside the heat source tower 1 and provides driving force for the gas flow inside the heat source tower 1.

[0073] To prevent the exhaust fan 14 from coming into contact with liquid, the exhaust fan 14 is located at the heat source outlet 117.

[0074] In this embodiment, the heat source tower heat pump system also includes a heat source spray head 11, which is disposed inside the heat source accommodating cavity 10. The heat source spray head 11 is connected to the liquid inlet of the heat source tower 1. The heat source spray head 11 sprays liquid toward the heat source packing area 12. Spraying is used to increase the contact area between the liquid and the gas, thereby achieving the effect of heat exchange.

[0075] When the heat source tower heat pump system is operating in winter, antifreeze is placed inside the heat source storage area 13. At this time, the heat source tower heat pump system is used to output the heated solution, that is, to output the high-temperature solution through the first pipe 36 and the second pipe 211.

[0076] Specifically, the first valve body 112, the second valve body 111, the third valve body 18, and the circulating air valve 27 are opened, while the inlet air control valve 28, the outlet air control valve 29, the fourth valve body 19, and the fifth valve body 110 are closed. The heat source heat pump system 3 is in heating mode. The solution inside the heat source storage area 13, driven by the heat source pump 16, flows through the first pipe 36 to the first circulation pipe 114, the second circulation pipe 115, and the connecting pipe 17, respectively. The liquid inside the first circulation pipe 114 interacts with the first heat exchanger 32. After heat exchange, the liquid is cooled and flows to the inlet of heat source tower 1. The liquid inside the second circulation pipe 115 is cooled after heat exchange with the third heat exchanger 44 and flows to the inlet of heat source tower 1. The liquid at the inlet of heat source tower 1 flows to the heat source spray head 11 and is sprayed onto the heat source packing area 12. The gas flowing through the heat source packing area 12 exchanges heat with the cooled solution to heat the liquid flowing to the heat source storage area 13. At the same time, the gas carries away the water in the solution to concentrate the solution. Since the first heat exchanger 32 is used for heat absorption, the second heat exchanger 34 releases heat to the first pipe 36 to heat the liquid inside the first pipe 36, thereby heating the liquid inside the first pipe 36. Meanwhile, the solution flowing into the regeneration storage tank 23 through the connecting pipe 17 is driven by the regeneration pump 24 and flows through the third pipe 25 to the regeneration packing area 22. The fourth heat exchanger 42 exchanges heat with the solution inside the third pipe 25 to heat the solution inside the third pipe 25. Then, the liquid sprayed from the third pipe 25 to the regeneration packing area 22 through the regeneration spray head is a high-temperature liquid. When the circulating gas flows through the regeneration packing area 22, it exchanges heat with the solution and is heated. The heated circulating gas flows to the regeneration surface cooler 26 to exchange heat with the liquid inside the second pipe 211 to heat the liquid inside the second pipe 211.

[0077] When the heat source tower heat pump system is operating under summer conditions, cooling water is placed inside the heat source liquid storage area 13. At this time, the heat source tower heat pump system is used to output the heated and cooled solution, and the first pipeline 36 outputs the cooled liquid.

[0078] Specifically, the inlet control valve 28, outlet control valve 29, fourth valve body 19, and fifth valve body 110 are opened, while the first valve body 112, second valve body 111, third valve body 18, and circulating air valve 27 are closed. The heat source heat pump system 3 is in cooling mode. The solution inside the heat source storage area 13, driven by the heat source pump 16, flows through the first pipe 36 into the first circulating pipe 114 and then towards the inlet of the heat source tower 1. The liquid inside the first circulating pipe 114 exchanges heat with the first heat exchanger 32 and is then cooled. The heated liquid flows to the inlet of the heat source tower 1. The liquid inlet of the heat source tower 1 flows to the heat source spray head 11 and is sprayed onto the heat source packing area 12. The gas flowing through the heat source packing area 12 exchanges heat with the heated solution to cool the liquid flowing to the heat source storage area 13. Since the first heat exchanger 32 is used to release heat, the second heat exchanger 34 absorbs heat from the first pipe 36 to cool the liquid inside the first pipe 36, thereby cooling the liquid inside the first pipe 36. Simultaneously, the liquid inside the regeneration storage tank 23, driven by the regeneration pump 24, flows through the third pipeline 25 to the regeneration packing area 22. The fourth heat exchanger 42 exchanges heat with the solution inside the third pipeline 25 to heat it. Consequently, the liquid sprayed from the third pipeline 25 to the regeneration packing area 22 via the regeneration spray head is a high-temperature liquid. Outside air enters the regeneration tower 2 through the regeneration air inlet, exchanges heat with the high-temperature liquid, and then flows out through the regeneration air outlet, ensuring that the liquid flowing to the regeneration storage tank 23 is a low-temperature liquid. The liquid inside the first pipeline 36 exchanges heat with the third heat exchanger 44 to be cooled, allowing the cooled liquid to be output from the first pipeline 36.
