For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0037] Existing large-scale air-cooled condensing units generally adopt a side-inlet and top-outlet method. Air flows into the condensing unit from a horizontal direction, and turns and flows upward after passing through the condenser for heat exchange. Since the condenser will produce condensed water during operation, a water receiving pan is set under the condenser to receive the condensed water, and a drainage hole is set on the water receiving pan to discharge the collected condensed water. However, the design of the water receiving pan in the prior art is unreasonable, and air can enter the drainage hole. This part of the airflow will directly bypass the condenser and flow to the air outlet under the action of the fan, that is, this part of the airflow does not participate in heat exchange, and the ineffective power consumption of the fan increases, which ultimately causes the problem of increased energy consumption of the air-cooled condensing unit. To this end, the present application provides a method such as Figures 1 to 6The condensing unit shown includes: a condenser 1; a water receiving pan 2, wherein the water receiving pan 2 is arranged below the condenser 1; a lower sealing plate assembly 3, wherein the condenser 1 is arranged on the water receiving pan 2 through the lower sealing plate assembly 3, and the lower sealing plate assembly 3 and the water receiving pan 2 together form a decompression chamber 31; a drainage gap 32 is provided on at least a portion of the area where the lower sealing plate assembly 3 contacts the water receiving pan 2, and a drainage port 23 is provided on the portion of the water receiving pan 2 that constitutes the decompression chamber 31. The condenser 1 is arranged on the water receiving pan 2 by using the lower sealing plate assembly 3, so that the condenser 1 can be reliably fixed, and the connection position of the condenser 1 and the water receiving pan 2 can be sealed to prevent air from entering. In addition, the lower sealing plate assembly 3 can enclose a decompression chamber 31 together with the water receiving pan 2, and a drainage slit 32 is provided to enable condensed water and / or rainwater to smoothly flow into the decompression chamber 31 and finally be discharged through the drain port 23. When the condensation unit produces condensed water and / or rainwater enters the condensation unit, the water will accumulate in the water receiving pan 2 and cause the water level to rise. At this time, the height of the water level is higher than the height of the drainage slit 32 and a water film is formed at the drainage slit 32. The drainage slit 32 is closed by using the tension of the water film. At this time, the water can Under the action of the drain slot 32, it is intermittently discharged, and the air cannot flow through the drain slot 32, thereby reducing the possibility of air intrusion. In addition, the drain slot 32 has a throttling effect. The negative pressure generated by the fan at the drain slot 32 will be weakened due to the throttling effect of the drain slot 32, thereby reducing the negative pressure at the drain port 23 and reducing the possibility of air entering the decompression chamber 31 through the drain port 23, further reducing the amount of air intruding through the drain port 23; even in the absence of rain, due to the throttling effect of the drain slot 32 and the action of the large cavity decompression chamber 31, the air pressure inside the condensation unit and the outside of the drain port 23 is basically equal, and no airflow movement will occur, thereby reducing the ineffective work of the fan and reducing the energy consumption of the condensation unit.
[0038] In order to ensure the drainage efficiency of the water receiving pan 2, the lower sealing plate assembly 3 has a top surface away from the water receiving pan 2, and a throttling hole 33 is arranged on the top surface, and the decompression chamber 31 is connected with the upper part of the lower sealing plate assembly 3 through the throttling hole 33. The condensed water generated by the condenser 1 and the rainwater entering the condensation unit will form a water film blockage near the throttling hole 33, and the water can accumulate on the lower sealing plate assembly 3. When the water reaches a certain height, the water film tension is destroyed under the action of gravity, so that the water can flow into the decompression chamber 31 through the throttling hole 33, so that the water can finally be discharged through the drain port 23. The joint action of the throttling hole 33 and the drainage seam 32 can fully ensure the drainage efficiency of the water in the condensation unit, and can also use the water film formed by water at the throttling hole 33 and the drainage seam 32 of the lower sealing plate assembly 3 to limit the flow of air. In particular, the throttling effect of the throttling hole 33 can make the air pressure on both sides of the throttling hole 33 basically equal, and no air flow movement will occur. Since there is no ineffective airflow intrusion, the ineffective work of the fan is reduced and the energy consumption of the condensing unit is reduced.
[0039] Specifically, the lower sealing plate assembly 3 includes a condenser support portion 34 and a drainage support portion 35. The shape of the condenser support portion 34 is the same as the cross-sectional shape of the condenser 1, and the condenser 1 is arranged on the water receiving pan 2 through the condenser support portion 34. The drainage support portion 35 is located on one side of the condenser support portion 34, and the throttle hole 33 is arranged on the top surface of the drainage support portion 35. The condenser support portion 34 can realize reliable fixed sealing between the lower end of the condenser 1 and the water receiving pan 2 according to the shape of the condenser 1, and the drainage support portion 35 is covered at the drainage port 23 to ensure the formation of the decompression chamber 31, to ensure the lower sealing plate assembly 3 has an obstructive effect on air intrusion, and the upper surface of the drainage support portion 35 forms a plane, so that water can be stored on the upper surface of the drainage support portion 35 to form a water film at the throttle hole 33, which is convenient for the arrangement of the throttle hole 33 and can also ensure the intermittent drainage of the throttle hole 33.
[0040] like Figure 2 and Figure 4As shown, the cross-section of the condenser 1 is V-shaped, the shape of the condenser support part 34 is V-shaped, and the drainage support part 35 is arranged in the condenser support part 34. The V-shaped condenser support part 34 is used to achieve reliable support and sealing of the condenser 1 with a V-shaped cross-section. At the same time, the V-shaped condenser 1 can divide the water receiving tray 2 into three parts. In order to ensure that the water in the three parts of the water receiving tray 2 can flow to the drain port 23 through the drainage slit 32, it is necessary to set the drainage support part 35 inside the V-shape. At this time, the water on the left and right sides of the condenser support part 34 can flow into the decompression chamber 31 through the drainage slit 32 on the condenser support part 34, and the water in the middle can flow into the decompression chamber 31 through the drainage slit 32 on the drainage support part 35, thereby ensuring that the water at each position in the water receiving tray 2 can flow into the decompression chamber 31 through the drainage slit 32, and finally be discharged through the drain port 23, thereby achieving the purpose of no invalid airflow intrusion, reducing the invalid work of the fan, and reducing the energy consumption of the condensing unit.
[0041] As another embodiment not shown, the cross section of the condenser 1 is U-shaped, the support portion of the condenser 1 is U-shaped, and the drainage support portion 35 is arranged in the condenser support portion 34. The U-shaped condenser support portion 34 is used to realize reliable support and sealing of the condenser 1 with a U-shaped cross section. At the same time, the U-shaped condenser 1 can divide the water receiving tray 2 into three parts. In order to ensure that the water in the three parts of the water receiving tray 2 can flow to the drain port 23 through the drainage slit 32, it is necessary to set the drainage support portion 35 inside the U shape. At this time, the water on the left and right sides of the condenser support portion 34 can flow into the decompression chamber 31 through the drainage slit 32 on the condenser support portion 34, and the water in the middle can flow into the decompression chamber 31 through the drainage slit 32 on the drainage support portion 35, thereby ensuring that the water at each position in the water receiving tray 2 can flow into the decompression chamber 31 through the drainage slit 32, and finally discharged through the drain port 23, thereby achieving the purpose of no invalid airflow intrusion, reducing the invalid work of the fan, and reducing the energy consumption of the condensing unit.
[0042] The condensing units in the prior art all adopt a horizontal air inlet and vertical air outlet mode. The fan is arranged above the condenser 1, and the air inlet direction of the fan directly points to the water receiving pan 2 below the condenser 1. Therefore, the fan will generate a large negative pressure at the water receiving pan 2, and this negative pressure will further increase the problem of wind leakage at the drain port 23 of the water receiving pan 2. For this reason, the condensing unit in the present application also includes an upper sealing plate assembly 4, which is arranged at the upper end of the condenser 1, and the upper sealing plate assembly 4 is sealed with the condenser 1, and the upper sealing plate assembly 4 is used to seal the condenser 1. The upper sealing plate assembly 4 blocks the upper end of the condenser 1. At this time, the condensing unit adopts the horizontal air intake and horizontal air outlet mode. The fan can be arranged on the side of the condenser 1. The air intake direction of the fan is horizontal. The negative pressure generated at the water receiving tray 2 is small, so that the problem of wind blow-through at the drain outlet 23 of the water receiving tray 2 can be reduced. In addition, the upper sealing plate assembly 4 is used to realize the horizontal air intake and horizontal air outlet of the condensing unit, which can avoid the exhaust short-circuit backflow of the condensing unit, reduce the number of air flow reversal, improve the heat exchange efficiency, reduce the power consumption of the fan, and achieve energy saving. At the same time, the change of air flow direction makes it unnecessary to set a avoidance space above the condensing unit. It can be installed indoors or outdoors, expanding the scope of application.
[0043] The condensing unit also includes a top sealing plate 5 and an electrical box 6. The top sealing plate 5 is arranged above the upper sealing plate assembly 4, and the top sealing plate 5 and the upper sealing plate assembly 4 cooperate to seal the upper end of the condenser 1. The electrical box 6 is arranged between the top sealing plate 5 and the upper sealing plate assembly 4. The top sealing plate 5 is used to further seal the upper end of the condenser 1 to prevent air from entering through the upper end of the condenser 1, thereby achieving the purpose of no invalid airflow entering, reducing the invalid work of the fan, and reducing the energy consumption of the condensing unit.
[0044] The condensing unit further includes a frame 7, the condenser 1, the upper sealing plate assembly 4 and the lower sealing plate assembly 3 are all arranged in the frame 7, and the top sealing plate 5 is arranged at the top surface of the frame 7. The frame 7 is used to limit the size of the condensing unit, so that the shape of the condensing unit is regular, which facilitates the arrangement and connection between the condensing unit and other condensing units, and also facilitates the installation and positioning of the condenser 1, the upper sealing plate assembly 4, the lower sealing plate assembly 3 and other structures in the condensing unit, thereby ensuring the structural stability of the condensing unit.
[0045] The frame 7 includes a rear crossbeam, a middle crossbeam, a connecting beam, a right vertical beam, a right rear column, a right sealing plate, a right front column, a connecting plate, a base component, a left front column, and a left vertical beam. The rear crossbeam is one of the frameworks of the frame 7, located at the upper rear, and is fixed to the left and right vertical beams by bolts to play a connecting and supporting role; the upper part of the condenser 1 is fixed to the middle crossbeam, the lower part is fixed to the water receiving tray 2, the left front part is fixed to the left front column or the connecting plate, and the right front part is fixed to the right front column or the connecting plate; the middle crossbeam is one of the frameworks of the frame 7, and the left and right ends are respectively fixed to the left and right vertical beams for fixing the upper part of the condenser 1; the connecting beam is located between the rear crossbeam and the middle crossbeam, and is used for connecting the rear crossbeam and the middle crossbeam; the right vertical beam is one of the frameworks of the frame 7, located at the upper right of the condensing unit, and the front and rear ends of the right vertical beam are respectively fixed to the right front column, On the right rear column, it is used to support and connect the middle crossbeam, rear crossbeam, etc.; the right rear column is one of the frameworks of the frame 7, located at the right rear of the condensing unit, with the lower part fixed on the base component, and the upper part connected to the right vertical beam, which plays a supporting and connecting role; the right front column is located at the right front of the condensing unit, with the lower part connected to the water tray 2, and is fixed as a whole on the right column assembly of the condenser 1, which plays a connecting and supporting role; the base component is located at the lower part of the unit, which is the main framework of the entire unit, and plays the role of installation, support, connection and lifting; the left front column is located at the left front of the condensing unit, with the lower part connected to the water tray 2, and is fixed as a whole on the left column assembly of the condenser 1, which plays a connecting and supporting role; the left vertical beam is one of the frameworks of the frame 7, located at the upper left of the condensing unit, and the front and rear ends are respectively fixed on the left front column and the left rear column, which are used to support and connect the middle crossbeam, rear crossbeam, etc.
[0046] In order to prevent the problem of exhaust short-circuit backflow in the condensing unit caused by the gas flowing through the gap between the frame 7 and the condenser 1, the condensing unit further includes an auxiliary sealing plate 71. The cross section of the frame 7 is rectangular. The auxiliary sealing plate 71 and the top sealing plate 5 together seal the top of the frame 7. The auxiliary sealing plate 71 is used to seal the top of the frame 7 to ensure that the airflow cannot enter the interior of the condensing unit through the top of the frame 7, thereby ensuring the working reliability of the condensing unit. Figure 4 and Figure 5As shown in the figure, the cross-section of the condenser 1 is V-shaped, the shape of the top sealing plate 5 is the same as the cross-section of the condenser 1, and the top surface of the frame 7 is rectangular. At this time, there is a triangular exposed area between the edge of the top sealing plate 5 and the edge of the frame 7. At this time, the shape of the auxiliary sealing plate 71 is the same as the shape of the exposed area, thereby completely sealing the top surface of the frame 7, avoiding the problem of wind blowing from the upper end of the frame 7 in the condensing unit, and improving the reliability of the condensing unit. In particular, when two condensing units are arranged in parallel, the triangular exposed area between the two condensing units will be combined into a larger triangular exposed area. At this time, a triangular sealing plate can be set at this larger triangular exposed area. The triangular sealing plate is located at the upper position between the two adjacent condenser 1 modules and is fixed by screws to play the role of windproof, rainproof and dustproof, and prevent some high-temperature exhaust air from short-circuiting and flowing back into the condenser 1, which is beneficial to energy saving; and for the condensing unit located at the end, a left right-angle sealing plate and a right right-angle sealing plate are set at the triangular exposed area at the end. The right right-angle sealing plate is located at the upper right and is fixed to the condenser 1 module and the right vertical beam by screws to play the role of windproof, rainproof and dustproof, and prevent some high-temperature exhaust air from short-circuiting and flowing back into the condenser 1; the left right-angle sealing plate is located at the upper left and is fixed to the condenser 1 module and the left vertical beam by screws to play the role of windproof, rainproof and dustproof, and prevent some high-temperature exhaust air from short-circuiting and flowing back into the condenser 1.
[0047] Furthermore, the condensing unit also has a left sealing plate and a right sealing plate. When the condensing unit is located at the end, for example, the condensing unit is located at the right end of all condensing units, a right sealing plate is arranged on the condensing unit, and the right sealing plate is located at the right end of the condensing unit, fixed on the right front column, the right rear column and the right vertical beam, to block wind, rain and dust, and prevent part of the high-temperature exhaust air from short-circuiting and flowing back into the condenser 1, which is beneficial to energy saving; similarly, for example, the condensing unit is located at the left end of all condensing units, a left sealing plate is arranged on the condensing unit, and the left sealing plate is located at the left end of the condensing unit, fixed on the left front column, the left rear column and the left vertical beam, to block wind, rain and dust, and prevent part of the high-temperature exhaust air from short-circuiting and flowing back into the condenser 1, which is beneficial to energy saving.
[0048] The condensing unit also includes a fan 8. The cross-section of the condenser 1 is V-shaped. The fan 8 is arranged at the opening of the V-shape, that is, the fan 8 is located on one side of the condenser 1 in the horizontal direction. The fan 8 can drive the airflow to flow horizontally to achieve horizontal air intake and horizontal air outlet of the condensing unit, reduce the negative pressure generated by the fan 8 at the water receiving tray 2, and thereby reduce the occurrence of air leakage from the drain outlet 23.
[0049] In order to ensure the working efficiency of the condensing unit, the number of the fans 8 is at least two, and all the fans 8 are arranged in parallel on one side of the condenser 1, and the working states of all the fans 8 are the same. By setting a plurality of fans 8, the air volume of the condensing unit is guaranteed, and the working efficiency of the condensing unit is improved. At the same time, the working states of all the fans 8 are the same, and the air volume received by the condenser 1 of the condensing unit can be synchronously adjusted to be uniform, thereby ensuring uniform heat exchange of the condenser 1, and further improving the working reliability of the condensing unit.

The water isolation area 21 is used to separate the connection structure between the base component 9 and the water receiving tray 2 from the water in the water receiving tray 2, so as to prevent the water in the water receiving tray 2 from corroding the connection structure and causing the problem of unreliable connection between the base component 9 and the water receiving tray 2.
[0051] Optionally, the condensing unit further includes a waterproof plate 22, which is disposed in the water receiving tray 2, and the waterproof plate 22 and the side wall of the water receiving tray 2 together form a water-isolating area 21. The waterproof plate 22 is used to separate the interior of the docking water tray 2, thereby realizing the water-isolating area 21 at the separation point in the water receiving tray 2, which facilitates the processing of the docking water tray 2. Moreover, the waterproof plate 22 can also achieve the effect of reinforcing ribs in the water receiving tray 2, thereby increasing the structural strength of the water receiving tray 2. Figure 2 As shown, a V-shaped waterproof plate 22 is provided on the side wall of the water receiving tray 2, and an L-shaped waterproof plate 22 is provided at the corner of the water receiving tray 2, thereby achieving separation of the connection structure provided on the water receiving tray 2 and the water in the water receiving tray 2, and also enhancing the connection strength of the connection structure of the water receiving tray 2.
[0052] Each condensing unit is provided with a separate water receiving tray 2, which is beneficial to the expansion of the unit capacity, prevents the integral water receiving tray 2 from welding deformation, resulting in unclean drainage, and avoids drainage interference between the condensing modules.
[0053] A condensing unit comprises the above-mentioned condensing unit.
[0054] The condensing unit also includes a compression unit, and all the condensing units are connected in parallel to the compression unit. The condensing unit also includes an electric control box and an electric control box mounting beam, which is located in the middle and upper right end of the condensing unit and is fastened to the right front column and the right rear column with a pair of bolts; the electric control box is located in the middle and upper right end of the condensing unit and is fixed on the electric control box mounting beam, which is the control center of the entire condensing unit, that is, the electric control box is electrically connected to the electrical boxes 6 of all condensing units, so that the working status of all condensing units can be controlled.
[0055] A closed structure is provided at the connection of two adjacent condensing units, and the connection position of the two adjacent condensing units is closed by the closed structure to avoid the problem of air leakage caused by gaps in the condensing unit, thereby improving the working efficiency of the condensing unit.
