Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment technology, and more particularly to a condenser and air conditioning system. Background Technology

[0002] With the advancement of green and efficient refrigeration solutions, high-efficiency and energy-saving equipment will become the mainstream choice in the market. In large commercial chillers, the heat exchanger, as the "heart" of the system's heat exchange, significantly affects the chiller's heat exchange efficiency. In shell-and-tube condensers used in chillers, high-efficiency condenser tubes condense superheated refrigerant vapor outside the tubes (shell side) into subcooled liquid refrigerant through cooling water flowing inside the tubes (tube side). This process specifically includes the following steps: first, the superheated vapor is cooled to saturated vapor; second, the saturated vapor condenses into saturated liquid refrigerant; and finally, the saturated liquid refrigerant is cooled into subcooled liquid refrigerant.

[0003] The performance degradation of high-efficiency condenser tubes in condenser bundles is primarily due to the formation of a liquid refrigerant film from the condensation of refrigerant vapor, which covers the heat transfer surface of the condenser tubes. This liquid film acts as a heat transfer resistance, leading to a decrease in the heat transfer performance of the condenser tubes. This phenomenon is particularly pronounced in multi-tube bundles. This is because, in the tube bundle, the liquid refrigerant discharged from the upper row of condenser tubes drips onto the lower row, causing liquid film accumulation on the tube walls of the lower condenser tubes (the liquid film gradually thickens), increasing the heat transfer resistance and reducing the condensation heat transfer coefficient.

[0004] Because condensers contain a large number of tube bundles, the entire vertical direction often includes multiple rows of condenser tubes. Traditional condensers have a centralized air intake at the top, and the refrigerant vapor condenses into liquid on the condenser tube wall. The liquid refrigerant drips downwards and collects under the action of gravity, resulting in a thicker liquid film on the surface of the condenser tubes as they go lower in the vertical direction. Since the liquid film is an additional thermal resistance (heat transfer requires passing through the liquid film), the heat exchange performance of the corresponding condenser tubes is worse.

[0005] Therefore, in order to improve the heat transfer coefficient of the condenser, it is urgent to improve the existing condenser. Summary of the Invention

[0006] One objective of this invention is to provide a condenser that solves the technical problem in the prior art where the liquid film on the surface of the condenser tubes becomes thicker as they move further down, resulting in poorer heat exchange performance. The numerous technical effects of the preferred embodiment of this invention are detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The condenser of the present invention includes an air inlet mechanism, a heat exchange tube mechanism, and a liquid collection mechanism. The air inlet mechanism includes an air inlet and N equalization chambers. The air inlet is connected to the equalization chambers. The equalization chambers are spaced apart and divide the heat exchange tube mechanism into (N+1) groups of heat exchange tubes. The liquid collection mechanism includes N groups of liquid collection components, each located at one of the uppermost N groups of heat exchange tubes. Gaseous refrigerant enters the equalization chamber through the air inlet and then enters the heat exchange tubes located above the equalization chamber. After exchanging heat with the heat exchange tubes, the gaseous refrigerant condenses into liquid refrigerant. The liquid collection components collect the liquid refrigerant condensed at each group of heat exchange tubes. Here, N is an integer greater than or equal to 2.

[0009] According to a preferred embodiment, the heat exchange tube group (N+1) is used to cool the liquid refrigerant collected by the liquid collection assembly into a subcooled liquid refrigerant.

[0010] According to a preferred embodiment, the air intake mechanism further includes an air intake plate, which is provided with N sets of openings, and the openings are used to connect the air distribution chamber and the air intake.

[0011] According to a preferred embodiment, the air inlet plate is further provided with an air outlet baffle, which is used to control the flow of gaseous refrigerant through the opening into the air equalization chamber.

[0012] According to a preferred embodiment, the gas equalization cavity is a cavity structure formed by a top plate, a bottom plate, and a first sealing plate and a second sealing plate located on both sides of the top plate and the bottom plate. The top plate is provided with an air passage, through which the gaseous refrigerant in the gas equalization cavity enters the heat exchange tube group located above the gas equalization cavity.

[0013] According to a preferred embodiment, the number of airways is multiple, and the airways are evenly distributed.

[0014] According to a preferred embodiment, the distance between the air passage and the upper surface of the top plate gradually increases from the middle of the top plate to the first sealing plate, and the distance between the air passage and the upper edge of the top plate gradually increases from the middle of the top plate to the second sealing plate.

[0015] According to a preferred embodiment, the liquid collection assembly includes a first liquid collection trough and a dispersion section, wherein a baffle is provided above the gas passage, and the baffle and the top plate form the first liquid collection trough; the dispersion section is provided on the side of the first sealing plate and the second sealing plate, and allows the liquid refrigerant collected in the first liquid collection trough to flow to the dispersion section.

[0016] According to a preferred embodiment, the projected width of the mouth shield in the horizontal direction is not less than the projected width of the airway in the horizontal direction.

[0017] According to a preferred embodiment, the top plate is inclined, the liquid collection assembly further includes a second liquid collection trough, and an end face baffle is provided on the lower side of the top plate, the end face baffle and the top plate forming the second liquid collection trough, so that the liquid refrigerant collected in the second liquid collection trough flows to the dispersion section.

[0018] According to a preferred embodiment, the dispersing section includes a dispersing plate and a vertical plate. The dispersing plate is horizontally arranged, the vertical plate is vertically arranged, and the end of the vertical plate is higher than the dispersing plate. A plurality of drip holes are uniformly arranged on the dispersing plate for supplying liquid refrigerant.

[0019] According to a preferred embodiment, there are multiple dispersion plates and vertical plates, and the dispersion plates are located at different heights, forming a stepped shape for the dispersion portion.

[0020] According to a preferred embodiment, N is 3.

[0021] The condenser provided by this invention has at least the following beneficial technical effects:

[0022] The condenser of the present invention includes an air inlet mechanism, a heat exchange tube mechanism, and a liquid collection mechanism. The air inlet mechanism includes an air inlet and N equalization chambers. The air inlet is connected to the equalization chambers, which are spaced apart and divide the heat exchange tube mechanism into (N+1) groups of heat exchange tubes. The liquid collection mechanism includes N groups of liquid collection assemblies, each located at one of the uppermost N groups of heat exchange tubes. Therefore, the condenser of the present invention, through the N equalization chambers and N groups of liquid collection assemblies, enables zoned air intake. Liquid refrigerant is generated through heat exchange in each group of heat exchange tubes, and then collected through the N groups of liquid collection assemblies. The condenser uses a layered collection system to collect liquid refrigerant, preventing it from dripping continuously downwards and causing an increasingly thick liquid film to cover the surface of the lower heat exchange tubes, which would severely degrade condensation performance. This significantly improves the overall heat exchange performance of the heat exchange tube bundle, thereby enhancing the condenser's heat exchange performance. On the other hand, existing air inlets are generally located above the condenser, causing the gaseous refrigerant to primarily exchange heat with the upper heat exchange tubes. The condenser of this invention achieves zoned air intake through N equalization chambers, allowing for uniform distribution of the gaseous refrigerant and improving the uniformity of air intake, thus further enhancing the condenser's heat exchange performance.

[0023] The condenser of this invention solves the technical problem in the prior art that the liquid film on the surface of the condenser tubes further down the condenser tubes is thicker, and the heat exchange performance of the condenser tubes is worse.

[0024] The second objective of this invention is to provide an air conditioning system.

[0025] The air conditioning system of the present invention includes the condenser described in any of the technical solutions of the present invention.

[0026] The air conditioning system provided by this invention has at least the following beneficial technical effects:

[0027] The air conditioning system of the present invention includes a condenser according to any of the technical solutions of the present invention. Due to the improved heat exchange performance of the condenser, the performance of the air conditioning system is improved. Attached Figure Description

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0045] The following is in conjunction with the instruction manual appendix. Figures 1-14 The condenser and air conditioning system of the present invention will be described in detail in Examples 1 to 3.

[0046] Example 1

[0047] This embodiment provides a detailed description of the condenser of the present invention.

[0048] The condenser in this embodiment includes an air inlet mechanism, a heat exchange tube mechanism, and a liquid collection mechanism. Preferably, the air inlet mechanism includes an air inlet 11 and N gas equalization chambers 12. The air inlet 11 communicates with the gas equalization chambers 12, and the gas equalization chambers 12 are spaced apart, dividing the heat exchange tube mechanism into (N+1) groups of heat exchange tubes 21, such as... Figures 1-8 As shown; the liquid collection mechanism includes N sets of liquid collection assemblies 31, which are located at the uppermost N sets of heat exchange tube groups 21, as shown. Figure 9 or Figure 10 As shown; gaseous refrigerant enters the gas equalization chamber 12 through the inlet 11, and then enters the heat exchange tube group 21 located above the gas equalization chamber 12. After exchanging heat with the heat exchange tube group 21, the gaseous refrigerant condenses into liquid refrigerant. The liquid collection assembly 31 is used to collect the liquid refrigerant condensed at each heat exchange tube group 21, such as... Figure 14 As shown. Preferably, N is an integer greater than or equal to 2.

[0049] The condenser of this embodiment, through N equalization chambers 12 and N sets of liquid collection assemblies 31, enables zoned air intake. Liquid refrigerant is generated through heat exchange in each set of heat exchange tubes 21, and then collected in layers by the N sets of liquid collection assemblies 31. This prevents the liquid refrigerant from continuously dripping downwards, causing an increasingly thick liquid film to cover the surface of the lower heat exchange tubes, which leads to severe degradation of condensation performance. This significantly improves the heat exchange performance of the entire heat exchange tube bundle, thereby enhancing the overall heat exchange performance of the condenser. On the other hand, conventional air inlets 11 are generally located at the top of the condenser, causing the gaseous refrigerant to primarily exchange heat with the upper heat exchange tubes. The condenser of this embodiment, through N equalization chambers 12, enables zoned air intake, allowing for uniform distribution of the gaseous refrigerant and improving the uniformity of air intake, thus further enhancing the heat exchange performance of the condenser. In other words, the condenser of this embodiment solves the problem in the prior art where the liquid film on the surface of the lower condenser tubes becomes thicker, resulting in poorer heat exchange performance.

[0050] According to a preferred embodiment, the (N+1)th heat exchange tube group 21 is used to cool the liquid refrigerant collected by the liquid collection assembly 31 into a subcooled liquid refrigerant. The (N+1)th heat exchange tube group 21 is the lowest heat exchange tube group, such as... Figure 3 The fourth heat exchange tube group 21-4 is shown. In the preferred embodiment of the condenser, the liquid refrigerant collected by the liquid collection component 31 drips downwards and undergoes preliminary subcooling through the heat exchange tube group 21 below the liquid collection component 31 (e.g., the second heat exchange tube group 21-2 located below the first dispersion section 312-1 subcools the liquid refrigerant collected in the first dispersion section 312-1; the third heat exchange tube group 21-3 located below the second dispersion section 312-2 subcools the liquid refrigerant collected in the second dispersion section 312-2). The refrigerant after preliminary subcooling then enters the (N+1)th heat exchange tube group 21 (also called the subcooling heat exchange tube group 21) for further subcooling, resulting in better subcooling effect and lower outlet liquid temperature.

[0051] According to a preferred embodiment, the air intake mechanism further includes an air intake plate 13, which has N sets of openings 131 for connecting the air distribution chamber 12 and the air inlet 11, such as... Figure 12 or Figure 13 As shown. More preferably, the air inlet 11 has a circular or square shape. In the preferred embodiment of the condenser, the air inlet plate 13 is provided with N sets of openings 131, that is, the number of sets of openings 131 matches the number of gas equalization chambers 12, with one set of openings 131 corresponding to one gas equalization chamber 12, so that the gaseous refrigerant entering through the air inlet 11 can enter the corresponding gas equalization chamber 12 through each set of openings 131. More preferably, the openings 131 are evenly distributed along the length direction of the air inlet plate 13, so that the gaseous refrigerant can be evenly supplied to the corresponding gas equalization chamber 12 through each set of openings 131.

[0052] According to a preferred embodiment, the air inlet plate 13 is further provided with an air outlet baffle 132, which is used to control the flow of gaseous refrigerant through the opening 131 into the air distribution cavity 12, such as... Figure 12 or Figure 13 As shown. Specifically, each set of openings 131 is provided with an outlet baffle 132. In the preferred embodiment of the condenser, the inlet plate 13 is also provided with an outlet baffle 132. Through the function of the outlet baffle 132, the flow direction of the gaseous refrigerant can be constrained, so that the gaseous refrigerant is discharged through the openings 131 to the corresponding gas equalization chamber 12.

[0053] According to a preferred embodiment, the gas equalization chamber 12 is a cavity structure formed by a top plate 121, a bottom plate 122, and a first sealing plate 123 and a second sealing plate 124 located on both sides of the top plate 121 and the bottom plate 122. An air passage 1211 is provided on the top plate 121, through which the gaseous refrigerant in the gas equalization chamber 12 enters the heat exchange tube assembly 21 located above the gas equalization chamber 12. Figures 3-8 As shown. In the preferred embodiment, the condenser has a gas equalization chamber 12, which is a cavity structure formed by a top plate 121, a bottom plate 122, and a first sealing plate 123 and a second sealing plate 124 located on both sides of the top plate 121 and the bottom plate 122. This structure ensures that the gaseous refrigerant entering the gas equalization chamber 12 can only be discharged from the gas passage 1211 on the top plate 121, thus ensuring that all gaseous refrigerant can be discharged into the heat exchange tube group 21 to participate in heat exchange.

[0054] According to a preferred embodiment, the number of airways 1211 is multiple, and the airways 1211 are evenly distributed, such as... Figure 4 , Figure 7 or Figure 9As shown. Preferably, from the middle of the top plate 121 to the first sealing plate 123, the distance between the air passage 1211 and the upper surface of the top plate 121 gradually increases; from the middle of the top plate 121 to the second sealing plate 124, the distance between the air passage 1211 and the upper edge of the top plate 121 gradually increases. In this preferred embodiment, the condenser has multiple air passages 1211, which are evenly distributed. This allows the vaporized refrigerant in the equalization chamber 12 to be evenly discharged through the air passages 1211, further improving the uniformity of the intake air and thus further improving the heat exchange performance of the condenser.

[0055] According to a preferred embodiment, the liquid collection assembly 31 includes a first liquid collection jacket 311 and a dispersion section 312, such as Figure 9 or Figure 14 As shown. A baffle plate 313 is provided above the air passage 1211, forming a first liquid collection groove 311 between the baffle plate 313 and the top plate 121, as... Figure 5 or Figure 14 As shown; the dispersion section 312 is disposed on the side of the first sealing plate 123 and the second sealing plate 124, and directs the liquid refrigerant collected in the first liquid collection tank 311 to the dispersion section 312, as shown. Figure 9 As shown. In this preferred embodiment, the liquid refrigerant generated by the heat exchange tube assembly 21 can be collected in layers through the first liquid collection jacket 311 below the heat exchange tube assembly 21. This prevents the liquid refrigerant from dripping continuously downwards, which would cause the surface of the lower heat exchange tubes to be covered with an increasingly thick liquid film, leading to severe attenuation of condensation performance. This greatly improves the heat exchange performance of the entire heat exchange tube bundle, thereby improving the heat exchange performance of the condenser. Furthermore, since the distance between the air passage 1211 and the upper edge of the top plate 121 gradually increases from the middle of the top plate 121 to the first sealing plate 123 and the second sealing plate 124, i.e., the air passage 1211 is inclined, and correspondingly, the baffle 313 is also inclined. This allows the first liquid collection jacket 311 to tilt towards the dispersion portions 312 on both sides, so that the liquid refrigerant collected in the first liquid collection jacket 311 can automatically flow to the dispersion portions 312, preventing excessive liquid refrigerant from overflowing from the first liquid collection jacket 311. Figure 4 , Figure 5 , Figure 7 or Figure 9 As shown.

[0056] According to a preferred embodiment, the projected width of the baffle 313 in the horizontal direction is not less than the projected width of the air passage 1211 in the horizontal direction. In this preferred embodiment, the baffle 313's projected width in the horizontal direction is not less than the projected width of the air passage 1211, thus allowing the baffle 313 to block the air passage 1211 and prevent liquid refrigerant generated by the heat exchange tube assembly 21 above the air passage 1211 from entering the gas equalization chamber 12 and affecting the condenser performance.

[0057] According to a preferred embodiment, the top plate 121 is inclined, the liquid collection assembly 31 further includes a second liquid collection groove 314, and an end face baffle 315 is provided on the lower side of the top plate 121. The end face baffle 315 and the top plate 121 form the second liquid collection groove 314, and the liquid refrigerant collected in the second liquid collection groove 314 flows to the dispersion section 312, such as... Figure 4 , Figures 7-10 or Figure 14 As shown. In the preferred embodiment, the condenser of this embodiment further includes a second liquid collecting jacket 314 in the liquid collecting assembly 31. The second liquid collecting jacket 314 can collect the liquid refrigerant generated by the heat exchange tube group 21 above the second liquid collecting jacket 314, and can also collect the liquid refrigerant overflowing from the first liquid collecting jacket 311, further avoiding the possibility of liquid refrigerant dripping downwards, thereby further improving the heat exchange performance of the condenser.

[0058] According to a preferred embodiment, the dispersion section 312 includes a dispersion plate 3121 and a vertical plate 3122. The dispersion plate 3121 is horizontally arranged, and the vertical plate 3122 is vertically arranged, with the end of the vertical plate 3122 higher than the dispersion plate 3121. A plurality of drip holes 31211 are uniformly arranged on the dispersion plate 3121 for the flow of liquid refrigerant. Figures 9-11 As shown. In the preferred embodiment of the condenser, the liquid refrigerant is collected by the first liquid collection jacket 311 and discharged into the liquid collection components 31 on both sides. It then drips evenly through the drip holes 31211 on the dispersion plate 3121 of the liquid collection component 31 onto the heat exchange tube group 21 below for initial subcooling. The initially subcooled liquid refrigerant then enters the (N+1)th group of heat exchange tube groups 21 (also called the subcooling heat exchange tube group 21) for further subcooling. Through multiple subcooling processes, the subcooling effect of the liquid refrigerant is further improved, resulting in a lower outlet temperature. In the preferred embodiment of the condenser, the dispersion plate 3121 is evenly provided with multiple drip holes 31211, allowing the liquid refrigerant to reach the heat exchange tube bundle below for subcooling via dripping. This dripping method improves the heat exchange effect between the liquid refrigerant and the heat exchange tube group 21, thereby enhancing the subcooling effect of the liquid refrigerant.

[0059] According to a preferred embodiment, there are multiple dispersing plates 3121 and vertical plates 3122, and the dispersing plates 3121 are located at different heights, and the dispersing portion 312 is formed in a stepped shape. Figure 9 or Figure 10 As shown. In the preferred embodiment, the condenser has a stepped dispersion section 312, which can collect and disperse liquid refrigerant through multiple stepped dispersion plates 3121, thereby further improving the uniformity of liquid refrigerant dispersion and avoiding the problem of uneven dispersion of liquid refrigerant caused by all liquid refrigerant accumulating below the dispersion plates 3121.

[0060] In this embodiment, the condenser first collects the liquid refrigerant generated during condensation and then discharges it in a centralized and directional manner, avoiding direct discharge to the lower heat exchange tubes and the resulting liquid film accumulation. This can greatly improve the performance degradation of the lower heat exchange tubes in the condenser and significantly enhance the overall heat transfer performance of the condenser tube bundle.

[0061] Example 2

[0062] This embodiment provides a detailed description of one preferred embodiment of the condenser of the present invention.

[0063] In this embodiment, the value of N in the condenser is 3.

[0064] The structure and operation of the condenser in this embodiment will be described in detail below.

[0065] The condenser in this embodiment has three gas equalization chambers, namely a first gas equalization chamber 12-1, a second gas equalization chamber 12-2, and a third gas equalization chamber 12-3; the three gas equalization chambers divide the heat exchange tube bundle into a first heat exchange tube group 21-1, a second heat exchange tube group 21-2, a third heat exchange tube group 21-3, and a fourth heat exchange tube group 21-4, as shown below. Figures 3-8 As shown. Preferably, the top plates of the first gas equalization chamber 12-1, the second gas equalization chamber 12-2, and the third gas equalization chamber 12-3 are all provided with air passages 1211. The gaseous refrigerant in the first gas equalization chamber 12-1 is discharged through the air passages 1211 and exchanges heat with the first heat exchange tube group 21-1. The gaseous refrigerant in the second gas equalization chamber 12-2 is discharged through the air passages 1211 and exchanges heat with the second heat exchange tube group 21-1. The gaseous refrigerant in the third gas equalization chamber 12-3 is discharged through the air passages 1211 and exchanges heat with the third heat exchange tube group 21-3.

[0066] Preferably, each of the first gas equalization chamber 12-1, the second gas equalization chamber 12-2, and the third gas equalization chamber 12-3 has a baffle plate 313 that slopes to both sides above each gas passage 1211. The baffle plate 313 completely blocks the gas passage 1211 to prevent liquid refrigerant from dripping into the first gas equalization chamber 12-1, the second gas equalization chamber 12-2, and the third gas equalization chamber 12-3. At the same time, a first liquid collection groove 311 is formed between the baffle plate 313 and the top plate 121. The liquid refrigerant is collected in the first liquid collection groove 311 and automatically discharged into the liquid collection components 31 on both sides. More preferably, the liquid collection assembly 31 includes a first liquid collection clamping groove 311 and a dispersing portion 312. The first liquid collection clamping groove 311 is located on the top plate of the first gas equalization chamber 12-1, the second gas equalization chamber 12-2, and the third gas equalization chamber 12-3. The dispersing portion 312 includes a first dispersing portion 312-1 located on both sides of the first gas equalization chamber 12-1 and a second dispersing portion 312-2 located on both sides of the second gas equalization chamber 12-2, such as... Figure 9 and Figure 10 As shown.

[0067] Preferably, the air intake plate 13 includes a first folded edge 13-1, a plate body 13-2, and a second folded edge 13-3, such as... Figure 13 As shown. A first opening 131-1 is formed on the first folded edge 13-1, and a first vent baffle 132-1 is also provided on the other side of the first folded edge 13-1. Part of the gaseous refrigerant is evenly discharged into the first gas equalization chamber 12-1 through the first opening 131-1. A second opening 131-2 is formed on the plate 13-2, and a second vent baffle 132-2 is also provided on the other side of the plate 13-2. Another part of the gaseous refrigerant is evenly discharged into the second gas equalization chamber 12-2 through the second opening 131-2. A third opening 131-3 is formed on the second folded edge 13-3, and a third vent baffle 132-3 is also provided on the other side of the second folded edge 13-3. The remaining gaseous refrigerant is evenly discharged into the third gas equalization chamber 12-3 through the third opening 131-3. Figure 13 As shown. More preferably, the first opening 131-1, the second opening 131-2, and the third opening 131-3 are square or round holes opened along the length of the pipe, so that the gas is evenly distributed along the length of the pipe. The second opening 131-2 is not opened at the position of the plate 13-2 directly opposite the air inlet 11, as shown. Figure 12 As shown.

[0068] The working process of the condenser in this embodiment is as follows: the condenser inlet 11 is located on the side. The high-temperature and high-pressure refrigerant gas discharged by the compressor enters the inlet plate 13 through the inlet 11. The gaseous refrigerant is evenly supplied to the first gas equalization chamber 12-1, the second gas equalization chamber 12-2 and the third gas equalization chamber 12-3 through the first opening 131-1, the second opening 131-2 and the third opening 131-3 respectively. After the gaseous refrigerant enters the first gas equalization chamber 12-1, the second gas equalization chamber 12-2, and the third gas equalization chamber 12-3, it is evenly discharged to the heat exchange tube group 21 at the upper part of the top plate 121 of the first gas equalization chamber 12-1, the second gas equalization chamber 12-2, and the third gas equalization chamber 12-3, and the heat is transferred to the cooling water in the condenser tube. After the gaseous refrigerant releases heat, it condenses into liquid refrigerant. The liquid refrigerant drips down into the first liquid collection trough 311 formed between the baffle 313 on the top plate 121 and the top plate 121. After the liquid refrigerant is initially collected by the first liquid collection trough 311, it is discharged into the liquid collection components 31 on both sides, and evenly drips into the heat exchange tube group 21 below through the dripping holes 31211 opened on the liquid collection components 31 for preliminary subcooling. Then it enters the subcooling tube bundle at the bottom for further subcooling, and finally is discharged from the condenser through the liquid outlet 41.
