Description

Technical Field

[0001] The invention relates to the technical field of gas condensers, in particular to a non-azeotropic refrigerant segmented heating shell and tube condenser. Background Art

[0002] A heat pump is a device that converts thermal energy from a low-temperature heat source into thermal energy from a high-temperature heat source. It uses a low-boiling-point working fluid as a refrigerant. After obtaining heat energy from low-temperature heat sources such as air, water, or soil in nature, it uses electricity to perform work and then provides usable heat energy from the high-temperature heat source to people. Heat pump refrigerants used to be generally freon, but freon has a destructive effect on ozone in the Earth's atmosphere. To protect the Earth's ecological environment, non-azeotropic refrigerants such as R404A, R407C, and R407F have gradually replaced freon. Furthermore, compared to pure component refrigerants, non-azeotropic refrigerants exhibit significant temperature glide during phase change. Therefore, the circulation efficiency of the heat pump system can be improved by matching the temperature of the refrigerant and the heat exchange fluid.

[0003] The condenser is a crucial component of a heat pump system. Shell-and-tube heat exchangers are the most commonly used condenser type in heat pump systems. Water flows in from the top of the heat exchanger, flushing several heating tubes and absorbing the heat released by the condensing refrigerant vapor within them, thus condensing the refrigerant vapor.

[0004] However, during use, existing shell-and-tube condensers exhibit a linear relationship between the temperature change of the water outside the tubes and the enthalpy difference. However, the condensation temperature of the non-azeotropic refrigerant vapor inside the tubes is not constant during the condensation process, but rather exhibits a significant drop along the heat exchange tubes, a phenomenon known as temperature glide. Consequently, the temperature change of the non-azeotropic refrigerant and the enthalpy difference exhibit a non-linear relationship. Consequently, the heat exchange temperature difference between the non-azeotropic refrigerant and water is not uniform along the heat exchange tubes, but rather exhibits temperature pinch points. This uneven heat exchange temperature difference increases the irreversible heat loss of the condenser. Therefore, a non-azeotropic refrigerant segmented heating shell-and-tube condenser is urgently needed to address this problem. Summary of the Invention

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] refer to Figure 1 The present invention provides a non-azeotropic refrigerant segmented heating shell and tube condenser, comprising a shell 1, a segmented tube sheet 13 fixedly connected to the inner side of the shell 1, the segmented tube sheet 13 dividing the shell 1 into a first chamber 11 and a second chamber 24, the side wall of the first chamber 11 and the side wall of the second chamber 24 are connected through an intermediate water inlet pipe 16, a flow regulating portion is provided in the middle of the intermediate water inlet pipe 16, an air intake assembly and a liquid discharge assembly are fixedly connected at both ends of the shell 1, the air intake assembly is located on the side close to the second chamber 24, a heating assembly is connected between the air intake assembly and the liquid discharge assembly, the heating assembly passes through the segmented tube sheet 13, the first chamber 11 is connected to the water inlet assembly, and the first chamber 11 and the second chamber 24 are both connected to the drainage assembly.

[0023] The segmented tube sheet 13 separates the shell 1 into a first chamber 11 and a second chamber 24 that do not interfere with each other. When used for the first time, the drainage component is closed and cooling water is injected into the first chamber 11 through the water inlet component. After the cooling water fills the first chamber 11, it enters the second chamber 24 through the intermediate water inlet pipe 16 and the flow regulating part, so that the second chamber 24 is also filled with cooling water. Then, the refrigerant vapor enters the heating component through the air inlet component. When the refrigerant vapor passes through the heating component, heat exchange is generated with the cooling water. After the refrigerant vapor condenses into liquid, it enters the drain component and is discharged. The cooling water that absorbs heat is discharged through the drainage component.

[0024] Cooling water is continuously input through the water inlet component, and the cooling water first generates heat exchange with the part of the heating component located in the first chamber 11 in the first chamber 11. The cooling water that has absorbed heat partially enters the drainage component, and partially enters the second chamber 24 through the intermediate water inlet pipe 16. The mass flow rate of the cooling water entering the second chamber 24 is controlled by the flow control unit, and the cooling water entering the second chamber 24 continues to generate heat exchange with the part of the heating component located in the second chamber 24, and then the cooling water is discharged through the drainage component. Through this arrangement, the temperature matching of the cold and hot fluids in the heat exchange process is improved, the influence of the uneven heat transfer temperature difference caused by the temperature pinch point is reduced, and the irreversible heat loss in the heat transfer process is reduced.

[0025] To further optimize the solution, the side walls of the first chamber 11 are respectively provided with a first section cooling water inlet 4 and a first section cooling water outlet 6, which are centrally symmetrically arranged. The first section cooling water inlet 4 is connected to the water inlet assembly, the first section cooling water outlet 6 is connected to one end of the intermediate water inlet pipe 16, the other end of the intermediate water inlet pipe 16 is connected to the second chamber 24, and the first section cooling water outlet 6 is connected to the drainage assembly.

[0026] like Figure 1 As shown, the first section cooling water inlet 4 is located at the upper left of the first chamber 11. The cooling water enters the first chamber 11 through the first section cooling water inlet 4 and completely immerses the heating component part located in the first chamber 11, so that the refrigerant vapor entering the heating component and the cooling water in the first chamber 11 produce heat exchange. The first section cooling water inlet 4 and the first section cooling water outlet 6 are centrally symmetrically arranged to ensure that the cooling water can completely cover the part of the heating component located in the first chamber 11 when flowing, thereby improving the heat exchange effect.

[0027] After the cooling water that has undergone preliminary heat exchange is discharged through the first cooling water outlet 6, part of it enters the second chamber 24 through the intermediate water inlet pipe 16 and the flow regulating part, and part of it enters the drainage component.

[0028] To further optimize the solution, the side walls of the second chamber 24 are respectively provided with a second section cooling water inlet 5 and a second section cooling water outlet 7, the second section cooling water inlet 5 and the second section cooling water outlet 7 are centrally symmetrically arranged, and the second section cooling water inlet 5 is connected to the end of the intermediate water inlet pipe 16 away from the first section cooling water outlet 6.

[0029] like Figure 1As shown, the second section cooling water inlet 5 is arranged at the upper left of the second chamber 24. The cooling water enters the second chamber 24 through the middle water inlet pipe 16 and the flow regulating part through the second section cooling water inlet 5. The cooling water continues to generate heat exchange with part of the heating components located in the second chamber 24 in the second chamber 24, and then enters the drainage component through the second section cooling water outlet 7.

[0030] To further optimize the solution, the flow regulating part includes an intermediate water inlet pump 22 and a flow regulating valve 21. The first section cooling water outlet 6 is connected to the water inlet end of the intermediate water inlet pump 22, the water outlet end of the intermediate water inlet pump 22 is connected to the water inlet end of the flow regulating valve 21, and the water outlet end of the flow regulating valve 21 is connected to the second section cooling water inlet 5.

[0031] The intermediate water inlet pump 22 is used to pump the cooling water in the first chamber 11 into the second chamber 24 , and the flow regulating valve 21 is used to control the mass flow of the cooling water.

[0032] To further optimize the solution, the heating assembly includes a plurality of heating tubes 10, which pass through the segmented tube sheet 13. The side walls of the heating tubes 10 are fixedly connected to the segmented tube sheet 13, and the two ends of the heating tubes 10 are respectively connected to the air intake assembly and the liquid discharge assembly.

[0033] In order to ensure the heating effect and uniformity, the heating tubes 10 are arranged in several layers, and each layer has several tubes arranged in parallel. There is a gap between two adjacent heating tubes 10 to facilitate the complete immersion of the heating tubes in water to ensure the heating effect.

[0034] The heating tubes 10 of the present invention may be arranged in a matrix, an inverted triangle, or a triangle, and various arrangements may be applicable to the present invention.

[0035] The present invention preferably has a plurality of heating tubes 10 arranged in a matrix.

[0036] A further optimized solution is that the air intake assembly includes an air intake cavity 8, which is located on one side of the second chamber 24, is fixedly connected to the end of the shell 1, and the air intake cavity 8 is connected to the air inlet 2 in the middle of the side away from the shell 1, and the air intake cavity 8 is connected to one end of several heating tubes 10.

[0037] A further optimized solution is that the drainage component includes a drainage chamber 9, which is located on one side of the first chamber 11, and is fixedly connected to the end of the shell 1. The bottom of the drainage chamber 9 is connected to a drainage port 3, and the drainage chamber 9 is connected to one end of several heating tubes 10.

[0038] Fixed tube sheets 12 are fixed to both ends of the shell 1, and the fixed tube sheets 12 are used to fix several heating tubes 10. The air inlet cavity 8 and the drainage cavity 9 are respectively fixed to the side of the fixed tube sheet 12 away from the shell 1, so that the air inlet cavity 8 and the drainage cavity 9 are not connected to the interior of the shell 1, thereby preventing the cooling water in the shell 1 from entering the air inlet cavity 8 and the drainage cavity 9.

[0039] The two ends of the heating tube 10 are respectively connected to the air inlet chamber 8 and the drainage chamber 9. The refrigerant vapor entering the air inlet chamber 8 through the air inlet 2 enters the several heating tubes 10, and heat exchange occurs with the cooling water in the shell 1 in the heating tube 10. The refrigerant vapor condenses into liquid and flows into the drainage chamber 9, and is discharged through the drainage port 3 set at the bottom thereof.

[0040] To further optimize the solution, the water inlet component includes an initial water inlet pipe 15, the outlet end of the initial water inlet pipe 15 is connected to the first section cooling water inlet 4, the inlet end of the initial water inlet pipe 15 is connected to the outlet end of the initial water inlet pump 23, and the inlet end of the initial water inlet pump 23 is connected to the initial water inlet valve 14.

[0041] The initial water inlet valve 14 is used to control the introduction of cooling water, and the initial water inlet pump 23 is used to pump cooling water into the first chamber 11 through the initial water inlet pipe 15 .

[0042] To further optimize the solution, the drainage component includes a first cooling water outlet pipe 17 and a second cooling water outlet pipe 18. The water inlet end of the first cooling water outlet pipe 17 is connected to a first cooling water outlet valve 19, and the first cooling water outlet valve 19 is connected to the first section cooling water outlet 6. The water inlet end of the second cooling water outlet pipe 18 is connected to a second cooling water outlet valve 20, and the second cooling water outlet valve 20 is connected to the second section cooling water outlet 7. The water outlet ends of the first cooling water outlet pipe 17 and the second cooling water outlet pipe 18 are both connected to the drainage main pipe.

[0043] The first cooling water outlet valve 19 is used to control the discharge of cooling water in the first cooling water outlet pipe 17, and the second cooling water outlet valve 20 is used to control the discharge of cooling water in the second cooling water outlet pipe 18. The first cooling water outlet pipe 17 and the second cooling water outlet pipe 18 are both connected to the drainage main pipe, and the cooling water involved in heat exchange is discharged uniformly from the drainage main pipe.

[0044] In practical applications, the position of the segmented tube sheet 13 of the present invention can be determined based on the minimum point of the heat exchange temperature difference between the non-azeotropic refrigerant and water when the non-azeotropic refrigerant vapor in the heating tube 10 condenses along the length direction of the heating tube 10.

[0045] In order to solve the problem of uneven heat exchange temperature difference between non-azeotropic refrigerant and cooling water, which leads to increased irreversible heat loss, for any heating section of the heating tube 10, that is, any micro-element section of the heating tube 10, the mass flow rate of the cooling water outside the heating tube 10 needs to match the enthalpy change per unit temperature of the non-azeotropic refrigerant vapor in the heating section of the heating tube 10, that is, to satisfy the following formula as much as possible:

[0046]

[0047] Among them, m c is the mass flow rate of cooling water outside the heating tube 10 on this micro-element segment, Δh c is the enthalpy change of the cooling water outside the heating tube 10 in this microelement segment, Δt c is the temperature change of the cooling water outside the heating tube 10 on the micro-element segment, m h is the mass flow rate of the non-azeotropic refrigerant vapor in the heating tube 10 on the micro-element segment, Δh h is the enthalpy change of the non-azeotropic refrigerant vapor in the heating tube 10 on the micro-element segment, Δt h is the temperature change value of the non-azeotropic refrigerant vapor in the heating tube 10 on the micro-element segment.

[0048] The heating tube 10 is divided into two heating sections by the segmented tube sheet 13. The two heating sections are located in the first chamber 11 and the second chamber 24 respectively. When the non-azeotropic refrigerant vapor is condensed, the mass flow rate m h The non-azeotropic refrigerant vapor enters the heating tube 10 from the air inlet 2, and passes through the heating section of the heating tube 10 located in the second chamber 24 and the heating section of the heating tube 10 located in the first chamber 11 in sequence. The condensate generated after the azeotropic refrigerant vapor heat exchange is discharged from the drain port 3.

[0049] Mass flow rate is m c1 The cooling water is fed into the first chamber 11 through the first cooling water inlet 4 by the initial water inlet pump 23 through the initial water inlet pipe 15 and filled with the refrigerant vapor in the local heating tube 10 in the first chamber 11. The mass flow rate of the refrigerant vapor in the local heating tube 10 in the first chamber 11 is m h , mass flow rate is m h Part of the refrigerant vapor condenses and releases heat, which in turn heats the cooling water. The heated cooling water m c1 The first cooling water outlet 6 is divided into two parts, wherein the flow regulating valve 21 is adjusted to open so that the mass flow rate m c2 The cooling water passes through the middle water inlet pipe 16 and enters the second chamber 24 from the second cooling water inlet 5, so that the cooling water fills the second chamber 24.

[0050] The residual refrigerant vapor in the heating tubes 10 in the first chamber 11 that has not condensed and released heat will completely condense and release heat in the heating tubes 10 in the second chamber 24, thereby causing the cooling water in the second chamber 24 to absorb the heat released by the condensation of the residual refrigerant vapor in the heating tubes 10 in the second chamber 24; the remaining mass flow m c1 -m c2 The cooling water is discharged through the first cooling water outlet pipe 17. The mass flow rate of the heated water in the second chamber 24 is m c2 The cooling water is discharged through the second cooling water outlet pipe 18.

[0051] For example, when the condensation pressure is 3 MPa, the saturated non-azeotropic refrigerant vapor R236fa / R32 (30% / 70%) with a mass flow rate of 10 kg / h and an inlet temperature of 62.6°C is introduced into the heating tube 10 from the air inlet 2, passes through the heat exchange sections in the first chamber 11 and the second chamber 24 in turn, and the saturated condensate is discharged from the drain port 3.

[0052] Cooling water with an inlet temperature of 30°C and a mass flow rate of 87.3 kg / h is delivered into the first chamber 11 through the initial water inlet pipe 15 by the initial water inlet pump 23 through the first section cooling water inlet 4, filling the first chamber 11. A part of the refrigerant steam with a mass flow rate of 10 kg / h in the heating tube 10 in the first chamber 11 condenses and releases heat to heat the cooling water.

[0053] The cooling water heated in the first chamber 11 is divided into two parts through the first cooling water outlet 6:

[0054] Adjust the opening of the flow control valve 21 so that cooling water with a mass flow rate of 36.8 kg / h passes through the intermediate water inlet pipe 16 and enters the second chamber 24 from the second section cooling water inlet 5, filling the space of the second chamber 24 and absorbing the heat released by the condensation of residual refrigerant vapor in part of the heating tube 10 in the second chamber 24; the remaining cooling water with a mass flow rate of 50.5 kg / h and a temperature of 32°C is discharged through the first section cooling water outlet 6.

[0055] The cooling water heated by the partial heating tube 10 in the second chamber 24 with a mass flow rate of 36.8 kg / h is discharged through the second cooling water outlet 7 .

[0056] The hot and cold fluid temperature pinch point occurs when the zeotropic refrigerant cools to approximately 57°C, while the cooling water temperature rises to 32°C. Segmented tube sheet 13 is located at this point. The zeotropic refrigerant inlet temperature is 62.6°C, the zeotropic refrigerant temperature at the segmented tube sheet is 57°C, and the zeotropic refrigerant temperature at drain port 3 is 55°C. The cooling water temperature at the first-stage cooling water inlet 4 is 30°C, the cooling water temperature at segmented tube sheet 13 is 32°C, and the cooling water temperature at the second-stage cooling water outlet 7 is 39.2°C. This results in an average temperature difference of 25°C between the hot and cold fluids in first chamber 11 and 24.2°C in second chamber 24.
