Description

A vertical industrial chiller and its vertical cooling water system Technical Field

[0001] The present invention relates to the field of air-conditioning systems, and in particular to a vertical industrial chiller and a vertical cooling water system thereof. Background Art

[0002] A chiller, also known as a freezer or refrigeration unit, is a large-scale refrigeration device that provides cooling water at a constant temperature, flow rate, and pressure. A chiller consists of four main components: a compressor, an evaporator, a condenser, and an expansion valve, which together achieve both cooling and heating effects. Chillers can be categorized as air-cooled or water-cooled, depending on the condenser cooling method.

[0003] Because horizontal evaporators have a high horizontality, horizontal condensers have a high heat transfer coefficient, and consume less cooling water, existing chillers typically use horizontal evaporators and condensers (the evaporator and condenser are collectively referred to as "two devices"). For example, the falling-film water-cooled screw chiller disclosed in Chinese patent application number CN201720203388.4 includes a compressor, which is a special falling-film screw compressor. The compressor is equipped with a secondary oil separator at the rear, an electrical control box is installed at the front of the compressor, a water-cooled condenser is installed below the compressor, a falling-film evaporator is installed below the secondary oil separator, and a chiller throttling device is installed below the falling-film evaporator. Among them, the falling-film evaporator is a horizontal shell-and-tube evaporator, and the water-cooled condenser is a horizontal shell-and-tube condenser.

[0004] However, horizontal chillers are typically over two meters long, resulting in bulky chiller designs and a large footprint. Furthermore, due to their length, standard transport elevators cannot directly load them, requiring specialized lifting equipment. This makes transporting and installing chillers very cumbersome. Furthermore, the large footprint of horizontal chillers makes installation difficult in smaller spaces, such as those with close building spacing (the horizontal distance between two building walls). Furthermore, the chiller's installation is easily affected by environmental factors, significantly complicating its installation and use.

[0005] Furthermore, a Chinese utility model patent with publication number "CN2856870Y" describes a large-capacity, multi-head screw chiller. Its technical features include four semi-hermetic twin-screw compressors, each stacked on two evaporators; two evaporators arranged in parallel and stacked on condensers; two independent refrigeration systems connecting the two semi-hermetic twin-screw compressors, one evaporator, and two condensers, each equipped with a shutoff valve, a filter drier, a sight glass, and an electronic expansion valve; the outlet pipes connecting the evaporators are combined into a main outlet manifold, and the inlet pipes connecting the evaporators are combined into a main inlet manifold. This chiller has the advantages of low cost, simple structure, and high operational reliability, and can be widely used in air conditioning and refrigeration environments requiring high-precision processability. This scheme utilizes two evaporators and four condensers, with the two evaporators arranged in parallel and stacked on the four condensers. However, the multiple condensers and the two evaporator groups in this scheme are independently connected by pipes, resulting in a complex connection structure. Summary of the Invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a vertical cooling water system, which connects various parts in a compact layout, greatly reduces the footprint of the chiller, and greatly facilitates the transportation and installation of the chiller.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0008] A vertical cooling water system includes a condenser, an electronic expansion valve, an evaporator and a compressor; the condenser, electronic expansion valve and compressor are provided in multiple groups, and the evaporator has multiple groups of refrigerant pipelines built in; multiple groups of condensers, electronic expansion valves, compressors and refrigerant pipelines in the evaporator are connected to form multiple refrigerant circuits through refrigerant pipelines; the evaporator has a built-in refrigerant pipeline, and the refrigerant in the refrigerant pipeline can achieve heat exchange with the refrigerant in the refrigerant pipeline; it is characterized in that: the evaporator is a vertical evaporator, the condenser is a horizontal condenser, multiple groups of condensers are stacked up and down and arranged on one side of the evaporator, and multiple groups of compressors are arranged horizontally side by side above the condenser.

[0009] The present invention adopts the above-mentioned technical solution, which relates to a vertical cooling water system. The vertical cooling water system adopts multiple groups of condensers, electronic expansion valves and compressors, and multiple groups of refrigerant pipes built into the evaporator are connected to form multiple independent refrigerant circuits. On the basis of meeting the cooling capacity of the chiller, this solution adopts multiple refrigerant circuits for collaborative cooling, so that a smaller condenser can be used. Furthermore, in order to make the overall layout of the vertical cooling water system compact and occupy less space; the evaporator of this solution adopts a vertical evaporator, which is larger in size but occupies vertical space; the two groups of condensers adopt horizontal condensers, but the condenser volume is smaller; thus, multiple groups of condensers are stacked up and down and set on one side of the evaporator, and multiple groups of compressors are arranged horizontally side by side above the condenser.

[0010] Based on the above scheme, the various parts of the vertical cooling water system are connected together in a compact layout, which greatly reduces the floor space of the chiller and greatly facilitates the transportation and installation of the chiller.

[0011] In a further embodiment, the lower end of the evaporator is fixed to a support base, and the refrigerant pipe inlet and outlet within the evaporator are arranged on the lower end surface of the evaporator; a through hole for routing the refrigerant pipe is constructed in the middle of the support base. In this solution, the vertical evaporator needs to consider the refrigerant flow issue. Since the refrigerant contains lubricant, the vertical evaporator adopts a bottom-in and bottom-out method with the support base raised to facilitate the flow of the refrigerant containing lubricant.

[0012] Furthermore, the refrigerant inlet of the evaporator is located at the upper end of the evaporator's side wall, and the refrigerant outlet is located at the lower end of the evaporator's side wall; a distributor is provided inside the evaporator on the inside of the refrigerant inlet to evenly distribute water circumferentially. The refrigerant inlet of a vertical evaporator is located at the upper end of the evaporator's side wall. Refrigerant enters the evaporator through the refrigerant inlet at the upper end. To ensure even distribution of the refrigerant after entering the evaporator, a distributor is provided on the inside of the refrigerant inlet. After the refrigerant flows in, it is evenly distributed circumferentially through the distributor. The distributor can be a circumferentially evenly arranged liquid balancing plate.

[0013] The vertical cooling water system described above can be configured without a cooling pump and cooling water tank. Instead, a cooling pump and cooling water tank can be added to the cooling water circuit. Alternatively, a cooling pump and cooling water tank are included; the cooling pump input is connected to the cooling water tank outlet, and the cooling pump output is connected to the refrigerant inlet of the evaporator.

[0014] Preferably, the outer wall of the condenser is provided with multiple legs and multiple connecting blocks; the legs and connecting blocks are arranged relative to each other on radial sides of the outer wall of the condenser, and the multiple legs and multiple connecting blocks are arranged axially along the outer wall of the condenser; the upper condenser is inverted, and the upper and lower condensers are fixedly connected by a connecting block. The legs of the lower condenser are used to be fixed to the bottom plate, and the lower ends of the multiple compressor groups are fixed to the legs of the upper condenser. In this solution, legs and connecting blocks are respectively provided on opposite radial sides of the multiple heat exchangers, generally arranged up and down; multiple legs and connecting blocks are provided, and the multiple legs and multiple connecting blocks are arranged axially along the outer wall of the heat exchanger to ensure the stability of the connection.

[0015] During installation, the upper heat exchanger is inverted, and the upper and lower heat exchangers are connected via a connecting base. This allows multiple heat exchangers to be stacked on top of each other. Specifically, the connecting base is provided with connecting holes, and the two connecting bases are respectively fixed to the connecting plate using screws. The connecting plate has strip holes corresponding to the connecting holes on the connecting base. Here, the connecting plate is used to achieve mutual connection, and the strip holes provided on it can be used for fine-tuning.

[0016] Preferably, the condenser is a water-cooled condenser, which includes a shell, and a sealing plate and a flange end plate respectively fixed to both sides of the shell; the flange end plate is constructed with liquid inlets and outlets and a connecting cavity, and the liquid inlets and outlets and the connecting cavity on the same flange end plate are separated and connected by a refrigerant pipeline arranged inside the shell; the two adjacent flange end plates are fixedly connected by a beam tube and connected to the connecting cavity of the two flange end plates.

[0017] This stacked condenser assembly comprises multiple condensers stacked and fixed one above the other. The condensers in this solution are water-cooled horizontal condensers, with one end of the condenser housing sealed by a sealing plate and the other end capped by a flange end plate. The flange end plates in this solution are constructed with separate liquid inlets and outlets and a connecting cavity. Unlike existing technologies, the flange end plates of two adjacent condensers are integrally connected by a beam tube, which connects the connecting cavities of the two flange end plates.

[0018] During use, the medium pipelines inside multiple groups of condensers are connected to the liquid inlet and outlet ports and the connecting cavity on the flange end plates. The refrigerant or coolant enters the medium pipeline inside the condenser through the liquid inlet and outlet ports of one of the condensers, and then flows into the connecting cavity. Since the flange end plates of the two condensers are connected through the beam tube, it flows through the beam tube to the inside of the other condenser; based on this, it flows out from the liquid inlet and outlet ports of the last condenser.

[0019] The above solution can realize series connection of multiple stacked condenser groups, simplifying the pipe connection; and the beam-tube is integrally fixed to two adjacent flange end plates, thereby strengthening the connection between the two adjacent condensers.

[0020] Preferably, a liquid balancing support plate is provided on the shell opening on the inner side of the flange end plate, and a plurality of upper through holes and a plurality of lower through holes are provided on the liquid balancing support plate, which are respectively communicated with the liquid inlet and outlet and the communicating cavity, and the upper through holes and the lower through holes are connected through the refrigerant pipeline. In this scheme, a liquid balancing support plate is provided on the shell opening on the inner side of the flange end plate, and the plurality of upper through holes and the lower through holes of the liquid balancing support plate are connected one by one through the internal medium pipeline, which is used to locate and install the internal medium pipeline, and at the same time has the effect of evenly distributing and collecting the medium, so as to ensure that the various medium pipelines in the heat exchanger are evenly distributed.

[0021] Preferably, a sealing ring is provided on the circumference of the flange end plate, and a baffle arranged radially is provided in the middle of the sealing ring; the baffle divides the middle area of ​​the sealing ring into a liquid inlet and outlet and a connecting cavity; when the flange end plate is fixedly connected to the outer side of the liquid equalizing support plate, the sealing ring and the baffle are both sealed against the outer end face of the liquid equalizing support plate, and the baffle is located between the upper through hole and the lower through hole of the liquid equalizing support plate. In this scheme, the sealing ring is used to ensure that the circumferential outer side of the flange end plate is sealed, and the baffle is used to seal and separate the liquid inlet and outlet and the connecting cavity. Furthermore, the liquid equalizing support plate is fixedly connected to the shell opening, and the sealing ring of the flange end plate and the circumferential outer side of the liquid equalizing support plate are provided with corresponding connecting holes, and are fixedly connected by a screw-fastening assembly.

Example

[0036] As shown in Figures 1 to 7, this embodiment relates to a vertical cooling water system comprising a condenser 1, an electronic expansion valve 2, an evaporator 3, and a compressor 4. Multiple sets of the condenser 1, electronic expansion valve 2, and compressor 4 are provided, and the evaporator 3 has multiple refrigerant pipelines built in. The multiple sets of condensers 1, electronic expansion valves 2, and compressors 4 are connected to the refrigerant pipelines within the evaporator 3 via refrigerant pipelines a to form multiple refrigerant circuits. The evaporator 3 has a built-in secondary refrigerant pipeline b, and the secondary refrigerant within secondary refrigerant pipeline b is capable of heat exchange with the refrigerant in the refrigerant pipeline.

[0037] This vertical cooling water system uses multiple sets of condensers 1, electronic expansion valves 2 and compressors 4, and multiple sets of refrigerant pipelines built into the evaporator 3 are connected to form multiple independent refrigerant circuits. On the basis of meeting the cooling capacity of the chiller, this solution uses multiple refrigerant circuits for collaborative cooling, so that a smaller condenser 1 can be used. Furthermore, in order to make the overall layout of the vertical cooling water system compact and occupy less space. The evaporator 3 of this solution is a vertical evaporator, and the condenser 1 is a horizontal condenser 1. Multiple sets of condensers 1 are stacked up and down and arranged on one side of the evaporator 3, and multiple sets of compressors 4 are arranged horizontally side by side above the condenser 1. The evaporator 3 of this solution uses a vertical evaporator. Although it is larger in size, it occupies vertical space. The two sets of condensers 1 use horizontal condensers, but the condenser 1 is smaller in size. In this way, multiple sets of condensers 1 are stacked up and down and arranged on one side of the evaporator 3, and multiple sets of compressors 4 are arranged horizontally side by side above the condenser 1. Based on the above scheme, the various parts of the vertical cooling water system are connected together in a compact layout, which greatly reduces the floor space of the chiller and greatly facilitates the transportation and installation of the chiller.

[0038] As shown in Figures 1 and 3, the lower end of the evaporator 3 is fixedly connected to the support base 31, and the inlet and outlet of the refrigerant pipeline in the evaporator 3 are arranged on the lower end surface of the evaporator 3. A through hole for routing the refrigerant pipeline is constructed in the middle of the support base 31. In this solution, the vertical evaporator needs to take into account the refrigerant flow problem. Since the lubricant is added to the refrigerant, the vertical evaporator adopts a bottom-in and bottom-out method after the support base 31 is raised to facilitate the flow of the refrigerant added with the lubricant. Furthermore, the refrigerant inlet of the evaporator 3 is placed at the upper end of the side wall of the evaporator 3, and the refrigerant outlet is placed at the lower end of the side wall of the evaporator 3. A distributor for circumferentially uniform water distribution is provided inside the evaporator 3 on the inner side of the refrigerant inlet. The refrigerant inlet of the vertical evaporator is located at the upper end of the side wall of the evaporator 3. The refrigerant enters the evaporator 3 through the refrigerant inlet at the upper end. To ensure that the refrigerant is evenly distributed after entering the evaporator 3, a distributor is required inside the refrigerant inlet. After the refrigerant flows in, it can be evenly distributed circumferentially through the distributor. The distributor can be a liquid balancing plate evenly arranged around the circumference.

[0039] As shown in Figures 1 and 2 , the vertical cooling water system of the above-described solution can be equipped without the cooling pump 5 and cooling water tank 6. In other embodiments, such as those shown in Figures 3 and 4 , a cooling pump 5 and cooling water tank 6 are also included. The input of the cooling pump 5 is connected to the outlet of the cooling water tank 6 , and the output of the cooling pump 5 is connected to the refrigerant inlet of the evaporator 3 .

[0040] As shown in Figures 5 and 6, the outer wall of the condenser 1 is provided with multiple legs 15 and multiple connecting blocks 16. The legs 15 and connecting blocks 16 are arranged oppositely on either radial side of the outer wall of the condenser 1, and are arranged axially along the outer wall of the condenser 1. The upper condenser 1 is inverted, and the upper and lower condensers 1 are fixedly connected by the connecting blocks 16. The legs 15 of the lower condenser 1 are used to be fixed to the base plate, and the lower ends of the multiple compressors 4 are fixed to the legs 15 of the upper condenser 1. In this solution, the multiple heat exchangers are provided with legs 15 and connecting blocks 16 on opposite radial sides, generally arranged in an upper and lower arrangement. Multiple legs 15 and connecting blocks 16 are provided, and are arranged axially along the outer wall of the heat exchanger to ensure connection stability. During installation, the upper heat exchanger is inverted, and the upper and lower heat exchangers are fixedly connected by the connecting blocks 16. This allows multiple heat exchangers to be stacked on top of each other. Specifically, the connection base 16 is provided with connection holes, and the two connection bases 16 are respectively fixed to the connection plate 17 using screw fixing components. The connection plate 17 is provided with strip holes 171 corresponding to the connection holes on the connection base 16. Here, the connection is achieved through the connection plate 17, and the strip holes 171 provided thereon can be used for fine adjustment.

[0041] As shown in Figures 5 to 7, the condenser 1 is a water-cooled condenser. The condenser 1 includes a shell 11, and a sealing plate 12 and a flange end plate 13 respectively fixed to both sides of the shell 11. The flange end plate 13 is constructed with a liquid inlet and outlet 131 and a connecting cavity 132. The liquid inlet and outlet 131 and the connecting cavity 132 on the same flange end plate 13 are separated and connected through a refrigerant pipeline arranged inside the shell 11. The two adjacent flange end plates 13 are integrally fixedly connected by a beam tube 133 and the connecting cavities 132 of the two flange end plates 13 are connected. The stacked condenser 1 group includes multiple groups of condensers 1 stacked and fixed up and down. The condenser 1 in its scheme is a water-cooled horizontal condenser. One end of the shell 11 of the condenser 1 is closed by a sealing plate 12, and the other end is covered by a flange end plate 13. The flange end plate 13 in this solution is constructed with separated liquid inlet and outlet ports 131 and a connecting cavity 132 . What is different from the prior art is that the flange end plates 13 of two adjacent condensers 1 are integrally fixedly connected by a beam tube 133 and the connecting cavities 132 of the two flange end plates 13 are connected.

[0042] During operation, the media pipelines within multiple groups of condensers 1 connect the liquid inlet and outlet ports 131 on the flange end plates 13 and the communication chamber 132. The refrigerant or brine enters the media pipeline within one condenser 1 through the liquid inlet and outlet ports 131 of that condenser 1 and then flows into the communication chamber 132. Because the flange end plates 13 of the two condensers 1 are connected via the beam tube 133, the refrigerant flows through the beam tube 133 into the interior of the next condenser 1, and continues in this manner until it flows out of the liquid inlet and outlet ports 131 of the last condenser 1.

[0043] The above solution can realize series connection of multiple stacked condensers 1, simplifying the pipe connection. In addition, the beam tube 133 is integrally fixed to two adjacent flange end plates 13, thereby strengthening the connection between the two adjacent condensers 1.

[0044] In a further solution, a liquid balancing support plate 14 is provided on the opening of the shell 11 on the inner side of the flange end plate 13. The liquid balancing support plate 14 is provided with a plurality of upper through holes 141 and a plurality of lower through holes 142 which are respectively connected to the liquid inlet and outlet ports 131 and the connecting cavity 132. The upper through holes 141 and the lower through holes 142 are connected via the refrigerant pipe b. In this solution, a liquid balancing support plate 14 is provided on the opening of the shell 11 on the inner side of the flange end plate 13. The plurality of upper through holes 141 and the lower through holes 142 of the liquid balancing support plate 14 are connected one-to-one through the internal medium pipes, which are used to position and install the internal medium pipes, and at the same time have the effect of evenly distributing and collecting the medium, so as to ensure that the various medium pipes in the heat exchanger are evenly distributed.

[0045] As shown in Figure 7, a sealing ring 135 is provided on the circumference of the flange end plate 13, and a baffle 136 is provided in the middle of the sealing ring 135 in the radial direction. The baffle 136 divides the middle area of ​​the sealing ring 135 into a liquid inlet and outlet 131 and a connecting cavity 132. When the flange end plate 13 is fixed to the outside of the liquid equalizing support plate 14, the sealing ring 135 and the baffle 136 are both sealed against the outer end surface of the liquid equalizing support plate 14, and the baffle 136 is located between the upper through hole 141 and the lower through hole 142 of the liquid equalizing support plate 14. In this solution, the sealing ring 135 is used to ensure that the circumferential outer side of the flange end plate 13 is sealed, and the baffle 136 is used to seal and separate the liquid inlet and outlet 131 and the connecting cavity 132. Furthermore, the liquid balancing support plate 14 is fixed to the opening of the shell 11 , and corresponding connecting holes 137 are provided on the circumferential outer side of the sealing ring 135 of the flange end plate 13 and the liquid balancing support plate 14 , and are fixed to each other through screw-fastening components.
