Description

Technical Field

[0001] The present application relates to the technical field of chillers, and in particular to an evaporative cooling integrated chiller. Background Art

[0002] Evaporative cooling integrated chillers are installed outdoors, such as on rooftops. Traditional evaporative cooling integrated chillers typically arrange the evaporative condenser and other cooling components in a left-right arrangement. However, due to the length of the evaporator, the overall length of the unit cannot be shortened, resulting in a longer unit and a larger footprint. In limited installation space, the evaporative condenser is designed to be narrow, affecting condensing efficiency. Summary of the Invention

[0003] Based on this, it is necessary to provide an evaporative cooling integrated chiller that can solve the above problems.

[0004] To solve the above technical problems, this application provides the following technical solutions:

[0005] An evaporative cooling integrated chiller, the evaporative cooling integrated chiller comprising:

[0006] The frame includes a first frame body and a second frame body, wherein the first frame body is located above the second frame body, wherein the second frame body is divided into a first installation area and a second installation area in the length direction of the frame;

[0007] An evaporative condenser comprising an evaporative condenser body and a water tank, wherein the evaporative condenser body and the water tank are connected in a water circulation manner, wherein the evaporative condenser body is installed in the area formed by the first frame, and the water tank is arranged in the first installation area and connected to the second frame;

[0008] an evaporator, disposed in the second installation area and connected to the second frame;

[0009] The projection of the evaporative condenser body toward the second frame along the height direction of the frame can cover the evaporator and the water tank.

[0010] It can be understood that the evaporative condenser body is arranged above the frame, and the water tank, compressor and evaporator are arranged below the frame, so as to make full use of the internal space of the frame, making the structure of the evaporative condenser, compressor and evaporator more compact. Through the reasonable structural arrangement of the evaporative condenser body, water tank and evaporator, the length of the evaporative cooling integrated chiller is reduced, and the footprint of the evaporative cooling integrated chiller is made smaller without affecting the condensation effect.

[0011] In one embodiment, the evaporative condenser further comprises a water receiving pan, which is arranged between the evaporative condenser body and the water tank along the height direction of the frame and is communicated with the evaporative condenser body and the water tank respectively;

[0012] The water receiving tray can guide the spray water flowing through the evaporative condenser body to flow back to the water tank.

[0013] It can be understood that the spray water is guided back to the water tank through the water receiving tray, so that the water tank can reduce the footprint of the water tank in the second frame, which is conducive to the compact structure of the unit.

[0014] In one embodiment, the water receiving tray is attached to the water tank and welded to the water tank;

[0015] Wherein, the projection of the evaporative condenser body toward the water receiving tray along the height direction of the frame is arranged in the water receiving tray.

[0016] It is understandable that placing the water receiving tray against the water tank and welding the water tank together forms a compact structure with the water receiving tray and the water tank in the height direction of the frame, and improves the installation stability of the water receiving tray.

[0017] In one embodiment, a plurality of air outlets are provided on the evaporative condenser body, and the plurality of air outlets are sequentially spaced apart along the length direction of the frame.

[0018] It is understandable that multiple air outlets are arranged on the evaporative condenser body, so that the air outlet area becomes larger. In this way, the wind speed passing through the air outlet can be reduced while the air volume remains unchanged, thereby reducing water loss and saving water resources.

[0019] In one embodiment, the evaporative cooling integrated chiller further includes a compressor, which is disposed in the second installation area and connected to the second frame;

[0020] The evaporator and the compressor are arranged on both sides of the second installation area in a width direction of the frame.

[0021] It can be understood that the arrangement of the compressor and the evaporator on both sides is beneficial to the overall weight balance of the unit, so that the evaporative cooling integrated chiller can be hoisted smoothly during installation.

[0022] In one embodiment, the evaporative cooling integrated chiller further includes an oil separator, which is installed in the second installation area and is located between the compressor and the evaporator along the width direction of the frame. The compressor, the oil separator, and the evaporative condenser body are sequentially connected along the flow direction of the refrigerant.

[0023] Wherein, the oil separator is provided with an exhaust pipe, and the oil separator is connected and communicated with the compressor through the exhaust pipe.

[0024] It can be understood that arranging the oil separator between the compressor and the evaporator is conducive to uniform weight distribution, and the oil separator is adjacent to the compressor, so that the distance between the oil separator and the compressor is shorter, so that the length of the exhaust pipe can be made shorter, which is conducive to reducing the resistance to the flow of refrigerant in the exhaust pipe and facilitating the circulation of refrigerant.

[0025] In one embodiment, the oil separator is further provided with an air distribution pipe, and the oil separator is connected and communicated with the evaporative condenser body through the air distribution pipe;

[0026] The gas distribution pipe includes a connecting section and a branching section that are connected and communicated with each other. One end of the connecting section away from the branching section is connected and communicated with the oil separator, wherein the branching section is symmetrically arranged relative to the center line of the connecting section.

[0027] It is understandable that the branching sections are arranged symmetrically, so that when the refrigerant is transported to the evaporative condenser body through the branching sections, the refrigerant can be evenly distributed.

[0028] In one embodiment, the evaporative cooling integrated chiller further includes an electrical control box, which is disposed in the first installation area and connected to the second frame, and is arranged on a side of the water tank away from the second installation area and electrically connected to the compressor.

[0029] It is understandable that, with such an arrangement, the electric control box is located close to the outside of the second frame, which is convenient for operation.

[0030] In one embodiment, the frame includes a column, and the column is arranged through the first frame body and the second frame body;

[0031] Wherein, the evaporative condenser body is fixedly connected to the column.

[0032] It is understandable that the evaporative condenser body is fixedly connected to the column to improve the installation stability of the evaporative condenser body on the first frame.

[0033] In one embodiment, the evaporative cooling integrated chiller further includes a chilled water pump, which is installed in the second installation area and communicates with the evaporator, and is used to transport the chilled water of the evaporator to the terminal equipment;

[0034] In which, along the width direction of the frame, the chilled water pump is located between the compressor and the evaporator, along the length direction of the frame, the projection of the oil separator at least partially overlaps with the projection of the chilled water pump, and the oil separator and the chilled water pump are arranged at intervals.

[0035] It is understandable that general units do not include a chilled water pump, while the evaporative cooling integrated chiller of the present application includes a chilled water pump, which does not require on-site installation by the user, shortening the construction period.

[0036] In one embodiment, the evaporative cooling integrated chiller further comprises a throttling element, wherein the throttling element is installed in the second installation area and is located above the evaporator, and along the height direction of the frame, the projection of the throttling element is located within the projection of the evaporator;

[0037] Along the flow direction of the refrigerant, the evaporative condenser body, the throttling element and the evaporator are connected in sequence.

[0038] It can be understood that arranging the throttling element in the second installation area is beneficial to the weight balance of the evaporative cooling integrated chiller.

[0039] Due to the application of the above solution, this application has the following advantages compared with the prior art:

[0040] The evaporative cooling integrated chiller for which protection is sought in this application arranges the evaporative condenser body above the frame and the water tank, compressor and evaporator below the frame, thereby fully utilizing the internal space of the frame, making the structure of the evaporative condenser, compressor and evaporator more compact, thereby making the evaporative cooling integrated chiller occupy a smaller area, and the compressor and evaporator are arranged on both sides, which is beneficial to the overall weight balance of the unit, so that the evaporative cooling integrated chiller can be hoisted smoothly during installation.

[0053] See also Figure 1 and Figure 4 An embodiment of the present application provides an evaporative cooling integrated chiller 100, comprising a frame 10, an evaporative condenser 20, a compressor 30, and an evaporator 40. The frame 10 is rectangular and includes a first frame body 11 and a second frame body 12. The first frame body 11 is located above the second frame body 12, wherein the second frame body 12 is divided into a first installation area 121 and a second installation area 122 along the length of the frame 10. The evaporative condenser 20 includes an evaporative condenser body 21 and a water tank 22. The evaporative condenser body 21 and the water tank 22 are connected in a water circulation manner. The evaporative condenser body 21 is installed in the first frame body 11, and the water tank 22 is disposed in the first installation area 121 and connected to the second frame body 12. The compressor 30 is disposed in the second installation area 122 and connected to the second frame body 12. The evaporator 40 is disposed in the second installation area 122 and connected to the second frame body 12. In this way, the internal space of the frame 10 is fully utilized, allowing the evaporative condenser 20, compressor 30, and evaporator 40 to be rationally arranged, resulting in a more compact structure. This reduces the footprint of the evaporative cooling integrated water chiller 100 without affecting the condensing effect. The evaporator 40 and compressor 30 are arranged on both sides of the second installation area 122 in the width direction of the frame 10, which is beneficial to the overall weight balance of the unit and ensures that the evaporative cooling integrated water chiller 100 is hoisted smoothly during installation.

[0054] Among them, the compressor 30, the evaporative condenser body 21 and the evaporator 40 are connected in sequence along the flow direction of the refrigerant, and the projection of the evaporative condenser body 21 toward the second frame body 12 along the height direction of the frame 10 can cover the compressor 30, the evaporator 40 and the water tank 22.

[0055] Specifically, the evaporative cooling integrated chiller 100 occupies an area ranging from 15 square meters to 18 square meters.

[0056] For example, when designing an evaporative cooling integrated chiller 100 with a power of 500kW, the existing left and right structure units occupy an area of ​​19.87 square meters, while the evaporative cooling integrated chiller 100 of the present application occupies an area of ​​15.66 square meters. The adoption of the solution of the present application can save more than 20% of the floor space.

[0057] like Figure 1 As shown, in one embodiment, the frame 10 includes a column 13, which is arranged to penetrate the first frame body 11 and the second frame body 12. The evaporative condenser body 21 is fixedly connected to the column 13, thereby improving the installation stability of the evaporative condenser body 21 in the first frame body 11. Specifically, the evaporative condenser body 21 and the column 13 are connected by bolts to facilitate disassembly and assembly.

[0058] like Figure 2 As shown, in one embodiment, the evaporative condenser body 21 is provided with a plurality of air outlets 211, which are sequentially spaced apart along the length of the frame 10. Because the evaporative condenser body 21 is disposed within the first frame body 11 above the frame 10, the evaporative condenser body 21 has a larger deployment area, allowing for a greater number of air outlets 211 to be disposed on the evaporative condenser body 21, resulting in a larger air outlet area. This reduces the wind speed passing through the air outlets 211 while maintaining the same air volume, thereby reducing the amount of water droplets carried by the air, minimizing water loss and conserving water resources.

[0059] Specifically, the air outlet 211 is circular, has a diameter of 800 mm, and is four in number. The four air outlets 211 are spaced apart in the longitudinal direction of the evaporative condenser body 21, fully utilizing the space above the evaporative condenser body 21. Of course, in other embodiments, the number of air outlets 211 can also be set to three or five, etc., and the size of each air outlet 211 can be adjusted according to needs and is not limited here.

[0060] In one embodiment, a variable frequency fan 212 is correspondingly installed in each of the air outlets 211 , and the multiple variable frequency fans 212 can be turned on or off according to actual needs to adjust the air volume to adapt to different ambient temperatures.

[0061] In one embodiment, the evaporative condenser body 21 includes a spray pipe 213, a nozzle, a condensing coil, a filler, and louvers 214. The nozzle is located below the spray pipe 213, the condensing coil is located below the nozzle, the filler is arranged between the condensing coil and the water receiving tray, and the louvers 214 are arranged on both sides of the filler along the width of the frame 10. The spray water flowing from the nozzle can be sprayed onto the condensing coil and flow to the filler below the condensing coil. The water receiving tray receives the spray water that flows through the filler.

[0062] Compared to existing units, the coverage area of ​​the first frame 11 of the present application is equal to the floor space of the evaporative cooling integrated chiller 100, and the condensing coil has a larger spread area, which can reduce the number of layers of the condensing coil, increase the contact spray area between the condensing coil and the spray water, and improve the heat exchange efficiency. Each heat exchange tube in the condensing coil can be designed to be shorter, reducing the flow resistance of the refrigerant in the heat exchange tube. If the structure of the condensing coil has too many layers, when the spray water is sprayed from the top of the condensing coil to the condensing coil, the part of the condensing coil at the bottom will not be able to effectively contact the spray water, thereby reducing the heat exchange effect.

[0063] In one embodiment, the evaporative condenser 20 further includes a water receiving pan, which is disposed between the evaporative condenser body 21 and the water tank 22 and is in communication with both the evaporative condenser body 21 and the water tank 22. The water receiving pan extends along the length of the frame 10 to receive and guide the spray water flowing through the evaporative condenser body 21 back to the water tank 22. The spray water is guided back to the water tank 22 via the water receiving pan. This reduces the footprint of the water tank 22 within the second frame 12, and the water tank 22 no longer occupies space in the height direction of the frame 10, resulting in a compact unit structure.

[0064] A cooling water pump 23 is installed outside the water tank 22 and is connected to the water tank 22. The cooling water pump 23 drives the water in the water tank 22 to the spray pipe 213, where it is sprayed out from the nozzle to form a spray water. The spray water flows sequentially through the water tank 22, the spray pipe, and the water receiving tray, forming a circulating water circuit. The arrangement of the water receiving tray and the water tank 22 facilitates water collection, maintaining the water level in the water tank 22 at a certain height, which facilitates the cooling water pump 23 to operate better. Even if water is not replenished in time, the larger cooling water tank 22 can still keep the cooling water pump 23 operating for about ten minutes.

[0065] In this embodiment, the water receiving tray is abutted against the water tank 22 and welded to the water tank 22, and the evaporative condenser body 21 is arranged in the water receiving tray along the projection toward the water receiving tray in the height direction of the frame 10, so that the water receiving tray and the water tank 22 form a compact structure in the height direction of the frame 10, and the installation stability of the water receiving tray is improved.

[0066] like Figure 5As shown, in one embodiment, the evaporative cooling integrated chiller 100 further includes a chilled water pump 41. The chilled water pump 41 is installed in the second installation area 122 and communicates with the evaporator 40. The chilled water pump 41 is used to transport the chilled water from the evaporator 40 to terminal equipment such as fan coil units or air outlets. The chilled water pump 41 drives the water circulation of the chilled water in the evaporator 40. In the width direction of the frame 10, the chilled water pump 41 is located between the compressor 30 and the evaporator 40. In the length direction of the frame 10, the projection of the oil separator 50 at least partially overlaps with the projection of the chilled water pump 41. The oil separator 50 and the chilled water pump 41 are spaced apart.

[0067] It is understood that while conventional chillers do not include a chilled water pump 41, the evaporative cooling integrated chiller 100 of the present application does include a chilled water pump 41, making the chiller highly integrated and eliminating the need for on-site installation by the user, thus shortening the construction period. The chilled water pump 41 is electrically connected to the electrical control box 70 so that the electrical control box 70 can control the on and off of the chilled water pump 41. This eliminates the need for the user to install an additional pump control box for control, facilitating installation.

[0068] like Figure 4 and Figure 5 As shown, in one embodiment, the evaporative cooling integrated chiller 100 further includes an oil separator 50, which is installed in the second installation area 122 and is located between the compressor 30 and the evaporator 40, which is conducive to uniform weight distribution. The compressor 30, the oil separator 50 and the evaporative condenser body 21 are connected in sequence along the flow direction of the refrigerant.

[0069] The oil separator 50 is provided with an exhaust pipe 51, which is connected to and communicates with the compressor 30 via the exhaust pipe 51. The high-temperature, high-pressure gaseous refrigerant at the outlet of the compressor 30 enters the oil separator 50 through the exhaust pipe 51. The adjacent arrangement of the oil separator 50 and the compressor 30 shortens the distance between the oil separator 50 and the compressor 30. This allows the exhaust pipe 51 to be shortened, which helps reduce the resistance to the flow of the refrigerant in the exhaust pipe 51 and facilitates the circulation of the refrigerant.

[0070] It can be understood that the resistance to refrigerant flow is proportional to the square of the flow velocity and is proportional to the length. Since the refrigerant flow velocity in the exhaust pipe 51 connecting and communicating the compressor 30 with the oil separator 50 is relatively high, and the refrigerant flow velocity in the intake pipe 31 connecting and communicating the compressor 30 with the evaporator 40 is relatively low, taking all factors into consideration, arranging a shorter exhaust pipe 51 is beneficial to reducing the resistance of the exhaust pipe 51, and the refrigerant flow velocity in the intake pipe 31 is relatively low, and the slightly longer pipeline has less effect on the resistance.

[0071] like Figure 4 and Figure 5As shown, in this embodiment, the oil separator 50 is further provided with an air distribution pipe 52. The oil separator 50 is connected and communicated with the evaporative condenser body 21 via the air distribution pipe 52. After the refrigerant is separated into gas and oil in the oil separator 50, the gaseous refrigerant is connected to the evaporative condenser body 21 via the air distribution pipe 52. The air distribution pipe 52 includes a connecting section and a branching section that are connected and communicated with each other. The end of the connecting section away from the branching section is connected and communicated with the oil separator 50, wherein the branching section is symmetrically arranged with respect to the center line of the connecting section. In this way, when the oil separator 50 transports the refrigerant to the condensing coil of the evaporative condenser body 21 via the air distribution pipe 52, the refrigerant is evenly distributed.

[0072] Specifically, the connecting section is substantially linear, and the bifurcated section is configured to be H-shaped, thereby realizing a specific implementation method in which the bifurcated section is symmetrically arranged relative to the center line of the connecting section.

[0073] like Figure 1 As shown, in one embodiment, the evaporative cooling integrated water chiller 100 further includes a throttling element 60, which is mounted in the second mounting area 122. The throttling element 60 is mounted in the second mounting area 122 and is located above the evaporator 40. Along the height direction of the frame 10, the projection of the throttling element 60 is located within the projection of the evaporator 40. Through the reasonable arrangement of the throttling element 60, the weight balance of the evaporative cooling integrated water chiller 100 is achieved. The throttling element 60 is respectively connected to the evaporator 40 and the evaporative condenser 20. After passing through the throttling element 60, the medium-temperature and high-pressure liquid refrigerant output by the evaporative condenser body 21 is reduced in pressure to a low-temperature and low-pressure liquid refrigerant, and then enters the evaporator 40, facilitating the operation of the unit.

[0074] In this embodiment, the throttling element 60 is configured as an electronic expansion valve. However, the present invention is not limited thereto. In other embodiments, the throttling element 60 may also be configured as a thermal expansion valve or a capillary tube.

[0075] like Figures 3 to 5 In one embodiment, the evaporative cooling integrated chiller 100 further includes an electrical control box 70. The electrical control box 70 is disposed within the first mounting area 121 and connected to the second housing 12. The electrical control box 70 is located on the side of the water tank 22 facing away from the second mounting area 122 and is electrically connected to the compressor 30. This arrangement positions the electrical control box 70 near the outside of the second housing 12 for easy operation. The electrical control box 70 is electrically connected to the compressor 30, the chilled water pump 41, and the cooling water pump 23, respectively, and is capable of controlling the operating states of the compressor 30, the chilled water pump 41, and the cooling water pump 23.

[0076] In summary, the refrigerant is compressed by the compressor 30 and becomes a high-temperature and high-pressure gas. When it enters the condensing coil in the evaporative condenser 20, it exchanges heat with the air and water and is condensed into a medium-temperature and high-pressure liquid refrigerant. It then flows through the throttling element 60, is throttled and reduced in pressure to a low-temperature and low-pressure liquid refrigerant, and then enters the evaporator 40. After absorbing the heat of the chilled water, it evaporates into a low-temperature and low-pressure gaseous refrigerant and is sucked into the compressor 30. After being compressed again, it enters the next refrigeration cycle, and the cycle repeats.

[0077] During cooling, the chilled water flowing through the evaporator 40 is cooled and then delivered to the terminal equipment via the chilled water pump 41 to provide cooling to the user. The chilled water absorbs ambient heat and then flows back to the evaporator 40, repeating this cycle to achieve the purpose of cooling the environment. The evaporative cooling integrated chiller 100 absorbs the heat of the chilled water. The refrigerant exchanges heat through the evaporative condenser 20, transferring the heat to the spray water. The spray water is then cooled by the incoming air and discharged into the atmosphere by the variable frequency fan 212.

[0078] The evaporative cooling integrated chiller 100 of the present application is a single cooling mode, which can adapt to provide cooling under different ambient temperatures. When the ambient temperature is relatively low, the cooling water pump 23 is turned off and the ambient temperature is used to cool the refrigerant in the condensing coil.

[0079] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
