Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to a refrigeration system. Background Technology

[0002] The electrical control box is a core component of the refrigeration system, responsible for the circuit control, signal processing, and power distribution of the refrigeration unit.

[0003] In the process of developing this application, the inventors discovered that the prior art has at least the following problems: When assembling a refrigeration system, the wiring of the electrical control box and the pre-installation of the refrigeration unit can be carried out simultaneously, requiring the pre-installation of wiring harnesses when wiring the electrical control box. After the wiring of the electrical control box and the pre-installation of the refrigeration unit are completed, the electrical control box is then installed onto the refrigeration unit, and the internal wiring of the refrigeration unit is performed, as well as connecting the pre-installed wiring harness of the electrical control box to the refrigeration unit. This easily leads to difficulties in separating strong and weak currents when wiring the electrical control box and the refrigeration unit, resulting in easily confused wiring, and consuming a lot of time in cable management, wiring, and routing, thus affecting the production efficiency of the refrigeration system.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] This application provides a refrigeration system to solve the technical problem of low assembly efficiency in existing refrigeration systems.

[0031] Please see Figure 1 The refrigeration system mainly includes: an electrical control box 101, a refrigeration unit 103, and a connecting component 102; the electrical control box 101 is connected to the refrigeration unit 103 through the connecting component 102.

[0032] The electrical control box 101 includes at least: a low-voltage cable unit 1011 and a high-voltage cable unit 1012.

[0033] The low-voltage cable unit 1011 and the high-voltage cable unit 1012 are set independently. The low-voltage cable unit 1011 includes a low-voltage cable harness, which includes N low-voltage cables. The high-voltage cable unit 1012 includes a high-voltage cable harness, which includes M high-voltage cables. N and M are both positive integers.

[0034] In practical applications, N low-voltage cables can be bundled together to form a low-voltage cable bundle, and M high-voltage cables can be bundled together to form a high-voltage cable bundle.

[0035] The connection assembly 102 includes a low-voltage connection unit 1021 and a high-voltage connection unit 1022. The low-voltage connection unit 1021 includes a low-voltage connector, and the high-voltage connection unit 1022 includes a first high-voltage connector and a second high-voltage connector.

[0036] The low-voltage connector connects to the low-voltage cables in the low-voltage cable unit, and the first high-voltage connector and the second high-voltage connector connect to the corresponding high-voltage cables in the high-voltage cable unit.

[0037] In one example, the cables inside the electrical control box 101 can be divided into two groups of wire harnesses: high-voltage cables and low-voltage cables, which are then routed and bundled separately. That is, a low-voltage cable unit 1011 and a high-voltage cable unit 1012 are independently set up in the electrical control box 101. The low-voltage cable unit 1011 is used for routing the low-voltage cables in the electrical control box 101, and the high-voltage cable unit 1012 is used for routing the high-voltage cables in the electrical control box 101.

[0038] In practical applications, after independently setting up low-voltage cable unit 1011 and high-voltage cable unit 1012 in the electrical control box 101, branches can be reserved at the wiring points, the routing paths of each cable in the electrical control box 101 can be specified, and cables of the same type can be bundled together. In this way, there is no need to manufacture the wiring yourself; you only need to connect the wires according to the corresponding positions of the branches of the determined path.

[0039] It should be noted that by independently setting up the low-voltage cable unit 1011 and the high-voltage cable unit 1012, it can be ensured that the cables of the electrical control box 101 are basically located inside the electrical control box 101, and the connection with the refrigeration unit 103 is achieved through connectors. In practical applications, apart from selecting cables between the electrical control box 101 and the refrigeration unit 103, there are basically no cables running from outside the electrical control box 101 to the refrigeration unit 103 during the entire production process.

[0040] It should also be noted that when the pre-processing of the refrigeration unit 103 and the wiring of the electrical control box 101 are not completed, the wiring of the refrigeration unit 103 wiring harness can be carried out first. The wiring harness in the refrigeration system provided by this application does not need to be produced offline; it only needs to be produced according to the specified wiring path and main branches for wiring.

[0041] In one embodiment, the low-voltage connector, the first high-voltage connector, and the second high-voltage connector each include a male and a female connector. One of the male and female connectors is installed inside the electrical control box, and the other is installed on the refrigeration unit 103. When wiring the electrical control box and the refrigeration unit 103, the corresponding male and female connectors are simply connected, thus simplifying the operation and improving assembly efficiency.

[0042] In one instance, such as Figure 2 As shown, there are at least two low-voltage connectors 102A connected in series. The low-voltage connector 102A at one end is connected to the first power supply and the first controller of the electrical control box 101, and the low-voltage connector 102A at the other end is connected to the refrigeration unit 103.

[0043] In practical applications, the low-voltage connector 102A is specifically connected to the sensor of the refrigeration unit 103.

[0044] It should be noted that the first power supply is the power supply for the refrigeration unit 103, specifically the power supply for the sensors in the refrigeration unit 103; the first controller can be used to control the output of the first power supply, thereby controlling whether electrical energy is transmitted to the refrigeration unit 103 through the low-voltage connector 102A to power the sensors of the refrigeration unit 103.

[0045] It is worth noting that since there are at least two low-voltage connectors 102A, the cable lengths between the first power supply and the first controller of the electrical control box 101 and the refrigeration unit 103 can be adapted. The specific number of low-voltage connectors 102A can be determined according to the application environment and user needs. This application does not impose specific limitations, and all such connectors are within the protection scope of this application.

[0046] It should also be noted that, in practice, to protect the low-voltage connector 102A, a circuit breaker can be added between the first power supply and the first controller of the electrical control box 101 and the low-voltage connector 102A, such as... Figure 3 As shown; the circuit breaker can be a protective device such as an air switch.

[0047] In one embodiment, such as Figure 4 As shown, one end of the first high-voltage connector 102B is connected to the second power supply and the second controller of the control box 101, and the other end of the first high-voltage connector 102B is connected to the refrigeration unit 103; one end of the second high-voltage connector 102C is connected to the third power supply of the control box 101 through the protection switch of the control box 101, and the other end of the second high-voltage connector 102C is connected to the refrigeration unit 103.

[0048] In practical applications, the first high-voltage connector 102B is specifically connected to the electric valve of the refrigeration unit 103, and the second high-voltage connector 102C is specifically connected to the refrigerant pump, water pump, and fan of the refrigeration unit 103.

[0049] Specifically, whether or not a water pump needs to be installed in the refrigeration unit 103 depends on the specific application environment and user needs. If the refrigeration unit 103 has spray requirements, then a water pump needs to be installed; otherwise, it does not need to be installed.

[0050] It should be noted that the second power source is the power supply for the refrigeration unit 103, specifically the power supply for the electric valve in the refrigeration unit 103; the second controller can be used to control the output of the second power source, thereby controlling whether electrical energy is transmitted to the refrigeration unit 103 through the first high-voltage connector 102B to supply power to the electric valve in the refrigeration unit 103.

[0051] Similarly, the third power source is the power supply for the refrigeration unit 103, specifically the power supply for the refrigerant pump, water pump, and fan in the refrigeration unit 103; the third controller can be used to control the output of the third power source, thereby controlling whether electrical energy is transmitted to the refrigeration unit 103 through the second high-voltage connector 102C to supply power to the refrigerant pump, water pump, and fan in the refrigeration unit 103.

[0052] It should be noted that the number of the third power supply, the third controller, and the second high-voltage connector 102C can be one, that is, the refrigerant pump, water pump, and fan in the refrigeration unit 103 share one first high-voltage connector 102B, one third power supply, and one third controller; of course, they can also be set up in multiple groups, that is, the refrigerant pump, water pump, and fan in the refrigeration unit 103 each use their corresponding first high-voltage connector 102B, third power supply, and third controller, or any two share one first high-voltage connector 102B, third power supply, and third controller, depending on the application environment and user needs, all of which are within the protection scope of this application.

[0053] It should also be noted that in practice, the second high-voltage connector 102C that connects to the refrigerant pump is usually also connected to the frequency converter in the refrigeration system.

[0054] exist Figure 4 Based on this, in another embodiment, such as Figure 5 As shown, there are at least two first power connectors 102B, which are connected in series. The first power connector 102B located at one end is connected to the second controller and the second power supply in sequence, and the first power connector 102B located at the other end is connected to the refrigeration unit 103.

[0055] Since there are at least two first high-voltage connectors 102B, multiple first high-voltage connectors 102B can be used depending on the distance between the second power supply and second controller of the control box 101 and the refrigeration unit 103, thus adapting to cables of any length. Multiple first high-voltage connectors 102B can be used when the distance between the second power supply and second controller of the control box 101 and the refrigeration unit 103 is greater than a preset distance. For example, when 9m < distance < 10m, two first high-voltage connectors 102B can be used.

[0056] It should be noted that when the number of first high-voltage connectors 102B is greater than 2, only one first high-voltage connector 102B can be installed on the electrical control box 101, and the rest of the first high-voltage connectors 102B can be installed on the refrigeration unit 103.

[0057] exist Figure 4 Based on this, in another embodiment, such as Figure 5As shown, there are at least two second high-voltage connectors 102C, which are connected in series. The second high-voltage connector 102C located at one end is connected to the third power supply through a protection switch, and the second high-voltage connector 102C located at the other end is connected to the refrigeration unit 103.

[0058] Since there are at least two second high-voltage connectors 102C, multiple second high-voltage connectors 102C can be used depending on the distance between the third power supply and third controller of the control box 101 and the refrigeration unit 103, thus adapting to cables of any length. Multiple second high-voltage connectors 102C can be used when the distance between the third power supply and third controller of the control box 101 and the refrigeration unit 103 is greater than a preset distance. For example, when 9m < distance < 10m, two second high-voltage connectors 102C can be used.

[0059] It should be noted that the protective switch in this application can be an air switch, that is, as shown below. Figure 6 or Figure 7 As shown, other existing circuit breakers may also be used, and this application does not specifically limit them, but they are all within the scope of protection of this application.

[0060] It is worth noting that the actual number of low-voltage connector 102A, first high-voltage connector 102B, and second high-voltage connector 102C can be determined based on the cable length between the electrical control box 101 and the cooling system 103. When the distance between the devices to be connected is too far, or if the processing steps require it, multiple connectors can be used to accommodate cables of any length, thereby expanding the applicable scenarios of this solution.

[0061] It should be noted that the refrigeration unit 103 in actual application can be composed of multiple units. When the refrigeration unit 103 includes multiple units, in order to avoid messy wiring, the number of low-voltage connection units 1021 and high-voltage connection units 1022 in the connection component 102 can be set to be equal to the number of units in the refrigeration unit 103. Each unit in the refrigeration unit 103 is connected through the corresponding connection unit.

[0062] It should also be noted that the location of the refrigeration unit 103 can be considered. For units with different upper and lower floors, the upper unit corresponds to a set of low-voltage connection unit 1021 and high-voltage connection unit 1022, and the lower unit corresponds to another set of low-voltage connection unit 1021 and high-voltage connection unit 1022.

[0063] In some embodiments, such as Figure 8As shown, the electrical control box 101 includes a baffle 104, which divides the electrical control box 101 into a first region and a second region. The first high-voltage connector 102B and the low-voltage connector 102A are located in the first region, and the second high-voltage connector 102C is located in the second region.

[0064] In practical applications, such as Figure 8 As shown, the first region can be located below the second region; of course, it is not limited to this, and can also be determined according to the application environment and user needs, all of which are within the protection scope of this application.

[0065] It should be noted that after setting the baffle 104 in the electrical control box 101, the strong and weak currents can be further separated to avoid mutual interference.

[0066] In practical applications, to ensure the waterproofness of the refrigeration system, the low-voltage connector 102A, the first high-voltage connector 102B, and the second high-voltage connector 102C can all be waterproof connectors.

[0067] When the low-voltage connector 102A is not a waterproof connector, the connection terminals of the low-voltage connector 102A and the first power supply and first controller of the control box 101 are located inside the control box 101. When the first high-voltage connector 102B and the second high-voltage connector 102C are not waterproof connectors, the connection terminals of the first high-voltage connector 102B and the second power supply and second controller of the control box 101, and the connection terminals of the second high-voltage connector 102C and the protection switch of the control box 101 are all located inside the control box 101. In other words, when the low-voltage connector 102A, the first high-voltage connector 102B, and the second high-voltage connector 102C are not waterproof connectors, the wiring terminals of each connector in the refrigeration system are located inside the control box 101, thereby ensuring the waterproofness of the system.

[0068] In one example, the low-voltage connector 102A, the first high-voltage connector 102B, and the second high-voltage connector 102C are each marked with silkscreen markings. When the control box 101 is connected to the refrigeration unit 103 via the connection assembly 102, the control box 101 and the refrigeration unit 103 are connected according to the corresponding connector silkscreen markings, thereby facilitating production identification and implementing mistaken wiring prevention.

[0069] For example, the low-voltage connector 102A can be a 24V connector, the first high-voltage connector 102B can be a 220V connector, and the second high-voltage connector 102C can be a 380V connector.

[0070] It is understood that the total number of the low-voltage connector 102A, the first high-voltage connector 102B, and the second high-voltage connector 102C in the refrigeration system provided in this application is at least 3, that is, the total number of the low-voltage connector 102A, the first high-voltage connector 102B, and the second high-voltage connector 102C in the refrigeration system provided in this application is 3+N, where N≥0.

[0071] Based on the above, the refrigeration system provided in this embodiment includes: an electrical control box 101, a refrigeration unit 103, and a connecting component 102; the electrical control box 101 is connected to the refrigeration unit 103 through the connecting component 102; the electrical control box 101 includes at least: a low-voltage cable unit 1011 and a high-voltage cable unit 1012; the connecting component 102 includes a low-voltage connection unit 1021 and a high-voltage connection unit 1022, the low-voltage connection unit 1021 includes a low-voltage connector 102A, the high-voltage connection unit 1022 includes a first high-voltage connector 102B and a second high-voltage connector 102C, the low-voltage connector 102A connects to the low-voltage cable in the low-voltage cable unit 1021, and the first high-voltage connector 102B and the second high-voltage connector 102C connect to the corresponding high-voltage cable in the high-voltage cable unit 1022. In this application, because the electrical control box 101 has independently set up a low-voltage cable unit 1011 and a high-voltage cable unit 1012, during the assembly of the refrigeration system, due to the setting of the low-voltage connection unit 1021 and the high-voltage connection unit 1022, the wiring of the electrical control box 101 and the pre-installation of the refrigeration unit 103 can be carried out simultaneously. Simultaneously, the internal wiring of the refrigeration unit 103 can be completed during the pre-installation process. Finally, after the electrical control box 101 is installed on the refrigeration unit 103, the electrical control box 101 and the refrigeration unit 103 are connected through the low-voltage connection unit 1021 and the high-voltage connection unit 1022. This improves the assembly efficiency of the refrigeration system and saves labor time. It also achieves separation of high and low voltage cables.

[0072] In addition, the low-voltage cable unit 1011 and the high-voltage cable unit 1012 of the electrical control box 101 can be routed and bundled separately, and branches can be reserved at the connection points to plan the wiring path and avoid the situation of messy wire harnesses.

[0073] It is worth noting that since there are many cables running out of the electrical control box 101, cable management, wiring, and routing are time-consuming and can easily lead to wiring errors. This application solves this problem by setting up a low-voltage cable unit 1011 and a high-voltage cable unit 1012, and by using a connecting component 102 to connect the electrical control box 101 to the refrigeration unit 103. This not only distinguishes between high and low voltage cables but also simplifies the wiring process and further avoids wiring errors.

[0074] Finally, the refrigeration system provided in this application allows for simultaneous wiring of the electrical control box 101 and pre-installation of the refrigeration unit 103. The assembly of the refrigeration unit 103 (wiring, cleaning, and packaging) does not require waiting for the electrical control box 101 wiring to be completed; these processes can be performed in parallel, further optimizing the installation workflow of the refrigeration system, breaking down production and processing steps, and solving the problem of production processing time. That is, even before the pre-processing of the refrigeration unit 103 and the wiring of the electrical control box 101 are completed, the wiring of the refrigeration unit 103 wiring harness can be performed first. The refrigeration system provided in this application does not require production wiring management; production only needs to wire according to the specified wiring path and main branches.
