Description

Technical Field

[0001] This application relates to the field of air conditioning testing technology, specifically to a testing device for cabinet air conditioners. Background Technology

[0002] With the rapid development of industrial technology and the digital economy, rack-mounted air conditioners are increasingly widely used in cooling and heat dissipation applications such as communication base stations, power distribution cabinets, and energy storage. At the same time, the demand for performance and reliability testing of rack-mounted air conditioners is also constantly increasing. Therefore, specialized rack-mounted air conditioner testing equipment is needed for long-term operational testing to verify their reliability and performance.

[0003] Existing testing methods for rack-mounted air conditioners primarily rely on enthalpy difference laboratories or thermal balance laboratories to verify their performance. However, these methods can only conduct short-term, phased tests and cannot perform long-term operational verification, nor can they simulate various conditions in real-world application environments, such as outdoor high temperatures, low temperatures, and humidity. Furthermore, existing testing methods have the following limitations:

[0004] Existing testing methods cannot test two air conditioning units simultaneously because they cannot perform comparative testing or truly simulate the master-slave linkage control mode. This greatly limits the verification of the linkage control logic of the cabinet air conditioner. Furthermore, the existing testing devices have relatively simple adjustment methods and cannot flexibly simulate different loads and environmental conditions, which limits the efficiency and accuracy of the test. Utility Model Content

[0005] In view of this, the main objective of this application is to provide a testing device for cabinet air conditioners, which helps to solve the problem that existing testing methods cannot provide multiple testing conditions for multiple cabinet air conditioners at the same time.

[0006] This application provides a testing device for a cabinet air conditioner, comprising:

[0007] The main test unit includes a cabinet simulation enclosure, air circulation components arranged on opposite sides of the cabinet simulation enclosure, electrical control components arranged outside the cabinet simulation enclosure, and operating condition simulation components arranged inside the cabinet simulation enclosure.

[0008] The test units are located on the opposite sides of the cabinet simulation enclosure in the main test unit, and each test unit is equipped with a cabinet air conditioner.

[0009] As shown above, two test units are respectively set on opposite sides of the rack simulation enclosure to accommodate rack air conditioners, allowing simultaneous testing of two rack air conditioners for performance comparison testing, and also realistically simulating the master-slave linkage control mode; on the rack simulation enclosure, the operating condition simulation component can flexibly simulate different load conditions and ambient temperatures, making the test operating condition adjustment more flexible, improving test efficiency and saving test resources; the air duct circulation component provides a convenient channel for airflow in the rack simulation enclosure and the two rack air conditioners; the electrical control component provides power support for the test operating conditions.

[0010] Optionally, the cabinet simulation enclosure includes: cabinet side panels, comprising multiple side panels forming a three-dimensional enclosure and positioned in the middle of the base component; corner posts, comprising multiple corner posts located between two adjacent cabinet side panels to connect the cabinet side panels; a cabinet top plate, positioned at the top of the cabinet side panels; and a base component including a cabinet bottom plate positioned at the bottom of the cabinet side panels, with the bottom of the cabinet bottom plate supporting two cabinet air conditioners at each end.

[0011] As shown above, the entire three-dimensional enclosure and the cabinet air conditioners at both ends are supported by the base components. The adjacent cabinet side panels are connected by corner columns, which can greatly improve the structural stability and strength of the entire testing device. It can also adapt to the testing needs of different models or sizes of cabinet air conditioners by replacing cabinet side panels of different sizes.

[0012] Optionally, the air circulation components include: air duct partitions, which are located on opposite sides inside the cabinet simulation enclosure, with an air duct inlet at the lower end of the air duct partitions; a middle partition, which is perpendicular to the two air duct partitions and installed in the middle of the lower end of the two air duct partitions, dividing the air duct inlet into two; and an air duct top plate, which is located at the top of the air duct partitions, with a fan mounting port in the middle of the air duct top plate and air duct outlets at both ends of the air duct top plate.

[0013] As shown above, air duct partitions are installed on opposite sides inside the cabinet simulation enclosure, and air inlets are installed at the lower end of the air duct partitions. A fan mounting port is set in the middle of the air duct top plate for installing the fan, and air outlets are set at both ends of the air duct top plate. Under the action of the fan, air can flow from bottom to top through the air ducts on both sides inside the cabinet simulation enclosure. The middle partition is set between the two cabinet air conditioners. The middle partition ensures that the two cabinet air conditioners do not blow air onto each other when supplying air, and ensures that the air supply of the two do not interfere with each other.

[0014] Optionally, the operating condition simulation components include: an EC blower, which is installed at the blower mounting port in the middle of the top plate of the duct; a heating component, which is installed on the duct partitions on both sides of the EC blower; a flow equalization plate, which is installed below the EC blower; and a temperature sensor, which is installed at the lower end of the flow equalization plate.

[0015] As shown above, the EC air supply fan is located at the upper part of the cabinet simulation chamber. The EC air supply fan works together with the heating components and can flexibly adjust the airflow speed and temperature. The air distribution plate can ensure that the heated air flows evenly and that the airflow temperature entering the cabinet air conditioner is uniform. The temperature sensor monitors the return air temperature inside the cabinet simulation chamber to maintain stable test conditions.

[0016] Optionally, the electrical control components include: an electrical control box with a water baffle plate on its top, air guide slots on both sides of the electrical control box, an exhaust fan on the air guide slots, and a cable hole on the bottom side of the electrical control box; and a handheld controller located at the top of the front panel of the electrical control box, with a handheld controller water baffle plate around its perimeter.

[0017] As shown above, the water baffles of the control box and the handheld device can effectively prevent rainwater or other liquids from entering the control box, making it particularly suitable for outdoor use. The air guide duct and exhaust fan guide natural fresh air into the control box through one side air guide duct, carrying away the heat generated inside, and then exhausting it through the other side air guide duct, which can maintain a suitable operating temperature inside the control box and prevent equipment failure or performance degradation due to overheating. The bottom of the control box is equipped with cable holes for easy access and organization of power cords and signal cables.

[0018] Optionally, the base component further includes: mounting brackets located on both sides of the cabinet bottom plate to support the cabinet air conditioner; support feet located at the lower end of the cabinet bottom plate; and casters located at the lower end of the cabinet bottom plate and around the support feet.

[0019] As shown above, the mounting bracket provides support for the entire cabinet simulation enclosure and cabinet air conditioner, and the casters enable the entire testing device to be easily moved to different locations or sites, greatly improving the flexibility and ease of use of the testing device; the support feet keep the testing device level and stable when it needs to be fixed in a fixed position.

[0020] Optionally, the unit under test includes a mounting plate, and the outer sides of two oppositely arranged cabinet side panels are fitted with mounting plates, which are equipped with cabinet air conditioners.

[0021] As mentioned above, by installing mounting plates on the outside of the rack-mounted enclosure, the rack air conditioner can be installed, making installation and disassembly simpler and more convenient.

[0022] Optionally, a cable passage hole is provided on the side panel of the cabinet equipped with the electrical control box, and a through hole corresponding to the cable passage hole is provided at the lower end of an air duct partition.

[0023] As shown above, the cable passage holes on the side panel of the cabinet are located below the electrical control box. Corresponding to the cable passage holes, through holes are provided on the air duct partition to avoid messy cable layout and facilitate the neat connection of power lines and signal lines to the electrical control box, thus optimizing the space utilization of the testing device.

[0024] Optionally, the two oppositely arranged cabinet side panels are provided with cabinet air outlets and cabinet air inlets corresponding to the air conditioning return air outlets and air conditioning supply air outlets of the cabinet air conditioner.

[0025] As shown above, the air return vent of the rack air conditioner corresponds to the air outlet on the side panel of the rack, and the air supply vent corresponds to the air inlet on the side panel of the rack. Furthermore, the positions of the air inlet and outlet are rationally planned according to the different sizes and interface requirements of the rack air conditioners. This ensures that the airflow can smoothly enter and exit the rack air conditioner and the rack simulation enclosure, and also enables the testing device to adapt to various models of rack air conditioners.

[0026] Optionally, the heating element includes an adjustable heater and a non-adjustable heater.

[0027] As described above, by adjusting the heating power of the adjustable heater according to specific load conditions, and providing a constant heat output from the non-adjustable heater, the testing device can cope with more diverse testing environments and conditions, thus improving the flexibility of temperature control.

[0028] In summary, the rack air conditioner testing device provided in this application has rack air conditioners mounted on the outer sides of the cabinet side panels on opposite sides of the rack simulation enclosure. The air supply vents at the bottom of the rack air conditioners correspond to the rack air inlets at the bottom of the cabinet side panels, and the air return vents at the top of the rack air conditioners correspond to the rack air outlets at the top of the cabinet side panels. This testing device can simultaneously test two rack air conditioners for comparative testing and can also realistically simulate the master-slave linkage control mode. A partition is provided in the middle of the cabinet side panels on opposite sides to prevent the two rack air conditioners from interfering with each other when supplying air into the rack simulation enclosure. Air duct partitions are respectively provided on the inner sides of the cabinet side panels on the other opposite sides of the rack simulation enclosure. The side panels together form the air ducts on both sides of the rack simulation enclosure. An air duct top plate is located at the upper part of the rack simulation enclosure, with an EC (Electronic Controlled Exhaust) fan positioned in the center of the top plate. Heating components are located on the side panels surrounding the EC fan. A flow equalization plate is located below the EC fan, with a temperature sensor at its lower end. This arrangement at the upper part of the rack simulation enclosure allows for flexible simulation of different loads and environmental conditions, improving testing efficiency and saving testing resources. The casters at the lower part of the rack simulation enclosure enable free movement of the testing device, making switching between testing scenarios more convenient. Support feet at the lower part of the rack simulation enclosure ensure stability when stationary. The testing device features a waterproof design, meeting the requirements for long-term outdoor use.

[0043] This application provides a testing device for a cabinet air conditioner, comprising:

[0044] The main test unit includes a cabinet simulation enclosure 100, air circulation components arranged on opposite sides of the cabinet simulation enclosure 100, electrical control components arranged outside the cabinet simulation enclosure 100, and operating condition simulation components arranged inside the cabinet simulation enclosure 100.

[0045] In the main test unit, the cabinet simulation enclosure 100 has two opposite sides where the test units are set up, and the test units are equipped with cabinet air conditioners.

[0046] Specifically, two test units are respectively set on opposite sides of the rack simulation enclosure 100 to accommodate rack air conditioners, allowing simultaneous testing of two rack air conditioners for performance comparison testing and realistic simulation of master-slave linkage control mode; on the rack simulation enclosure 100, the operating condition simulation component can flexibly simulate different load conditions and ambient temperatures, making the test operating condition adjustment more flexible, improving test efficiency and saving test resources; the air duct circulation component provides a convenient channel for airflow in the rack simulation enclosure 100 and the two rack air conditioners; the electrical control component provides power support for the test operating conditions.

[0047] Optionally, the cabinet simulation enclosure 100 includes: cabinet side panels 101, which comprise multiple panels, the cabinet side panels 101 forming a three-dimensional enclosure and disposed in the middle of the base component 104; corner posts 102, which comprise multiple corner posts 102 respectively located between two adjacent cabinet side panels 101 to connect the cabinet side panels 101; cabinet top plate 103, which is disposed at the top of the cabinet side panels 101; and base component 104, which includes a cabinet bottom plate 1041 disposed at the bottom end of the cabinet side panels 101, the two ends of the cabinet bottom plate respectively supporting two cabinet air conditioners.

[0048] Specifically, the base component 104 supports the entire three-dimensional enclosure and the cabinet air conditioners at both ends, and the corner columns 102 connect the adjacent cabinet side panels 101, which can greatly improve the structural stability and strength of the entire test device. It can also adapt to the test requirements of different models or sizes of cabinet air conditioners by replacing the cabinet side panels 101 of different sizes.

[0049] Optionally, the unit under test includes a mounting plate 140, and the mounting plate 140 is mounted on the outer side of two oppositely arranged cabinet side panels 101. The mounting plate 140 is equipped with a cabinet air conditioner.

[0050] Specifically, the cabinet air conditioner is installed by mounting a mounting plate 140 on the outside of the cabinet simulation enclosure 100, making installation and disassembly simpler and more convenient.

[0051] Optionally, the two oppositely arranged cabinet side panels 101 are provided with cabinet air outlets and cabinet air inlets corresponding to the air conditioning return air outlet and air conditioning supply air outlet of the cabinet air conditioner.

[0052] Specifically, the air return vent of the rack air conditioner corresponds to the rack air outlet on the side panel 101 of the rack, and the air supply vent of the rack air conditioner corresponds to the rack air inlet on the side panel 101 of the rack. Furthermore, the positions of the rack air inlet and rack air outlet are rationally planned according to the rack air conditioners of different sizes and interface requirements. This ensures that the airflow can smoothly enter and exit the rack air conditioner and the rack simulation enclosure 100, and also enables the testing device to adapt to various models of rack air conditioners.

[0053] like Figure 1 The external structure of the test device for the rack-mounted air conditioner shown includes a main test unit consisting of an external rack-mounted simulation enclosure 100. Test units are located on the left and right sides of the main test unit, which can be designated as a first test unit and a second test unit. The first test unit is equipped with a first rack-mounted air conditioner 201, and the second test unit is equipped with a second rack-mounted air conditioner 202. The first rack-mounted air conditioner 201 and the second rack-mounted air conditioner 202 can be rack-mounted air conditioners of the same size or different sizes. The two test units have a certain degree of flexibility and can simultaneously accommodate rack-mounted air conditioners of different sizes. Figure 1As shown, the size of the first rack air conditioner 201 is larger than that of the second rack air conditioner 202, meaning the first rack air conditioner 201 is a large-size air conditioner and the second rack air conditioner 202 is a small-size air conditioner. The unit under test can be constructed using a mounting plate 140, which secures the rack air conditioner with screws. The mounting plate 140 can be flexibly adjusted according to the installation dimensions of the first rack air conditioner 201 and the second rack air conditioner 202, ensuring applicability to tests of different models of rack air conditioners and thus having wider applicability. The air conditioner's return air vent is located at the upper outer side of the rack simulation enclosure 100, and its air conditioner supply air vent is located at the lower outer side of the rack simulation enclosure 100. The bottom ends of the first rack air conditioner 201 and the second rack air conditioner 202 are flush. Therefore, the rack air inlets at the lower end of the rack simulation enclosure 100 are opposite and located on the same horizontal plane, and the rack air outlets at the upper end of the rack simulation enclosure 100 are opposite. The two rack air outlets can be located on the same horizontal plane of the rack simulation enclosure 100 (see [reference]). Figure 5b At the same height position shown, the airflow exiting from the rack exhaust vents located on opposite sides of the rack simulation enclosure 100 enters the air conditioning return vent of the rack air conditioner. After being cooled by the rack air conditioner, the airflow flows from the air conditioning supply vent of the rack air conditioner into the interior of the rack simulation enclosure 100 through the rack air inlet. The airflow between the rack air conditioner and the rack simulation enclosure 100 is as follows: Figure 5b As shown.

[0054] like Figure 1 and Figure 4 As shown, the cabinet simulation enclosure 100 includes four cabinet side panels 101, a cabinet top plate 103, a cabinet bottom plate 1041, and corner posts 102. The four cabinet side panels 101 form a rectangular three-dimensional enclosure. The adjacent corners between the four cabinet side panels 101 are connected by corner posts 102. The top of the four cabinet side panels 101 is covered by the cabinet top plate 103, and the bottom of the four cabinet side panels 101 is installed with the cabinet bottom plate 1041.

[0055] Optionally, the air circulation component includes: an air duct partition 110, which is located on opposite sides inside the cabinet simulation enclosure 100, and an air duct inlet is provided at the lower end of the air duct partition 110; a middle partition 111, which is perpendicular to the two air duct partitions 110 and is installed in the middle of the lower end of the two air duct partitions 110, and the middle partition 111 divides the air duct inlet into two; and an air duct top plate 112, which is located at the top of the air duct partitions 110, and a fan mounting port is provided in the middle of the air duct top plate 112, and air duct outlets are provided at both ends of the air duct top plate 112.

[0056] Specifically, air duct partitions 110 are respectively installed on opposite sides inside the cabinet simulation enclosure 100, and air duct inlets are installed at the lower end of the air duct partitions 110. A fan mounting port is provided in the middle of the air duct top plate 112 for installing a fan. Air duct outlets are provided at both ends of the air duct top plate 112. Under the action of the fan, air can flow from bottom to top through the air ducts on both sides inside the cabinet simulation enclosure 100. A middle partition 111 is set between the two cabinet air conditioners. The middle partition 111 ensures that the two cabinet air conditioners do not blow air onto each other when supplying air, and ensures that the air supply of the two do not interfere with each other.

[0057] Optionally, a cable passage hole is provided on the side panel 101 of the cabinet equipped with the electrical control box 130, and a through hole corresponding to the cable passage hole is provided at the lower end of an air duct partition 110.

[0058] Specifically, the cable passage hole on the side panel 101 of the cabinet is located below the electrical control box 130. The air duct partition 110 has through holes at the corresponding positions of the cable passage hole to avoid messy cable layout and facilitate the neat connection of power lines and signal lines to the electrical control box 130, thus optimizing the space utilization of the test device.

[0059] like Figure 2 The internal structure of the air circulation component shown includes an air duct top plate 112 located below the cabinet top plate 103. Air duct outlets are located on both sides of the air duct top plate 112, with one side's outlet consisting of three parallel rectangular holes. A fan mounting port is located in the center of the air duct top plate 112, where the EC blower 120 from the operating condition simulation component can be installed. Inside the cabinet simulation enclosure 100, air duct partitions 110 are located on opposite sides. Air duct inlets are located at the lower end of the air duct partitions 110, and through holes corresponding to cable routing holes are located above the air duct inlets. The air duct partitions 110 and the cabinet... The side panel 101 forms an airflow duct. A middle partition 111 is provided between two opposing airflow partitions 110. The middle partition 111 is parallel to the two cabinet side panels 101 on which the cabinet air conditioner is installed. The middle partition 111 is perpendicular to the two airflow partitions 110. From the perspective of looking down inside the cabinet simulation box 100, the top cross-section of the middle partition 111 and the two airflow partitions 110 forms an "I" shape. Thus, the middle partition 111 divides the inside of the cabinet simulation box 100 into two chambers, left and right. The middle partition 111 also divides the airflow inlet at the lower end of the airflow partition 110 into two chambers, left and right. Air duct partitions 110 are distributed on opposite sides inside the cabinet simulation enclosure 100. A middle partition 111 is installed in the middle of the air duct partitions 110 to separate the air supply of the first cabinet air conditioner 201 and the second cabinet air conditioner 202 to prevent mutual interference. The air supply of the cabinet air conditioners flows from bottom to top through the air duct partitions 110 on both sides and finally converges at the top inside the cabinet simulation enclosure 100 for mixing.

[0060] Optionally, the operating condition simulation components include: an EC blower 120, which is installed at the blower mounting port in the middle of the top plate 112 of the air duct; a heating component 121, which is installed on the air duct partitions 110 on both sides of the EC blower 120; a flow equalization plate 122, which is installed below the EC blower 120; and a temperature sensor 123, which is installed at the lower end of the flow equalization plate 122.

[0061] Specifically, the EC air supply fan 120 is installed at the upper part of the cabinet simulation box 100. The EC air supply fan 120 works together with the heating component 121 to flexibly adjust the speed and temperature of the airflow. The air distribution plate 122 can ensure that the heated air flows evenly and that the airflow temperature entering the cabinet air conditioner is uniform. The temperature sensor 123 monitors the return air temperature inside the cabinet simulation box 100 to maintain stable test conditions.

[0062] Optionally, the heating element 121 includes an adjustable heater and a non-adjustable heater.

[0063] Specifically, the heating power of the adjustable heater is adjusted according to the specific load conditions, while the non-adjustable heater provides a constant heat output, enabling the testing device to cope with more diverse testing environments and conditions and improving the flexibility of temperature control.

[0064] like Figure 3 The internal structure of the test device for the rack air conditioner shown is as follows: the working condition simulation component is assembled inside the upper part of the rack simulation box 100. The EC air supply fan 120 is installed at the fan installation port in the middle of the air duct top plate 112. Heating components 121 are set on the air duct partitions 110 on both sides of the EC air supply fan 120 at a position flush with the EC air supply fan 120. The heating components 121 include one adjustable heater and three non-adjustable heaters. A flow equalization plate 122 is set below the EC air supply fan 120 and the heating components 121. Two temperature sensors 123 are set at the lower end of the flow equalization plate 122. The flow equalization plate 122 is provided with mesh holes. The airflow exits from the top to the mesh holes to ensure that the return air temperature of the first rack air conditioner 201 and the second rack air conditioner 202 is uniform.

[0065] like Figure 5a The diagram shows the airflow direction of the test device. When the EC blower 120 is initially turned on, the airflow enters the interior of the air duct through the air inlet and flows from bottom to top. It then passes through the air outlet and the blower installation port in sequence and enters the middle of the cabinet simulation box 100. After being heated by the heating component 121, it flows through the flow equalization plate 122.

[0066] Optionally, the electrical control components include: an electrical control box 130, with a water baffle 1301 at its top, air guide ducts 1302 on both sides of the electrical control box 130, an exhaust fan 1303 on the air guide ducts 1302, and a cable hole at the bottom of the electrical control box 130; and a handheld controller 131, located at the top of the front panel of the electrical control box 130, with a handheld controller water baffle 1311 around the handheld controller 131.

[0067] Specifically, the water baffle 1301 of the electrical control box and the water baffle 1311 of the handheld device can effectively prevent rainwater or other liquids from entering the electrical control box 130, making it particularly suitable for outdoor use. The air guide duct 1302 and the exhaust fan 1303 guide natural fresh air into the electrical control box 130 through one side air guide duct 1302, remove the heat generated inside, and then exhaust it through the other side air guide duct 1302, which can maintain a suitable operating temperature inside the electrical control box 130 and prevent equipment failure or performance degradation due to overheating. The bottom side of the electrical control box 130 is provided with a cable hole for easy access and organization of power cords and signal lines.

[0068] like Figure 1 and Figure 3 As shown, an electrical control box 130 is mounted on the side panel 101 of the cabinet simulation enclosure 100. A water baffle 1301 is installed at the top of the electrical control box 130. Air guide ducts 1302 are respectively installed on the left and right sides of the electrical control box 130. An exhaust fan 1303 is installed on the side of the air guide duct 1302 closest to the heat source, i.e., an exhaust fan 1303 is installed on the side of the air guide duct 1302 closest to the cabinet air conditioner. Natural fresh air enters the electrical control box 130 through the bottom of one side of the air guide duct 1302, while hot air inside the electrical control box 130 is exhausted through the exhaust fan 1303 from the bottom of the other side of the air guide duct 1302, ensuring that the electrical control box 130 is always at a suitable operating temperature. A handheld device 131 is installed on the front panel of the electrical control box 130 for easy access in this testing device. The device is operated from the outside. The handheld device 131 is equipped with a handheld device water baffle 1311 on the top and left and right sides. The water baffle 1301 of the control box and the handheld device water baffle 1311 can ensure that no rainwater enters the control box 130, which meets the waterproof requirements of the test device. A knob is provided on one side of the middle of the front panel of the control box 130, and the knob is located near the air guide duct 1302. A cable hole is provided on the bottom side of the control box 130. A cable passage hole is provided on the side panel 101 of the cabinet where the control box 130 is located and below the control box 130. The cable of the working condition simulation component enters the interior of the control box 130 through the through hole on the air duct partition 110, the cable passage hole corresponding to the position of the through hole, and the cable hole on the bottom side of the control box 130.

[0069] Optionally, the base component 104 further includes: a mounting bracket 1042, which is located on both sides of the cabinet bottom plate to support the cabinet air conditioner; a support foot cup 1043, which is located at the lower end of the cabinet bottom plate; and casters 1044, which are located at the lower end of the cabinet bottom plate and are located around the support foot cup 1043.

[0070] Specifically, the mounting bracket 1042 provides support for the entire cabinet simulation enclosure 100 and the cabinet air conditioner, and the casters 1044 enable the entire test device to be easily moved to different locations or sites, greatly improving the flexibility and ease of use of the test device; the support feet 1043 keep the test device level and stable when it needs to be fixed in a fixed position.

[0071] like Figure 1-4 As shown, the mounting brackets 1042 located on both sides of the cabinet base plate 1041 are respectively inverted U-shaped support structures. The inverted U-shaped support structures support the bottom of the cabinet air conditioner. A crossbeam structure is set in the middle of the inverted U-shaped support structure. The crossbeam structure is installed on the side of the cabinet base plate 1041. At the middle position of the two mounting brackets 1042, that is, at the lower end of the cabinet base plate 1041, four support feet 1043 are set. Four universal wheels 1044 are set around the four support feet 1043, which can freely move the test device of the cabinet air conditioner. The universal wheels 1044 can also be set at the lower end of the cabinet base plate 1041 or the lower end of the corner column 102 of the cabinet simulation box 100. When the test device of the cabinet air conditioner needs to be fixed, the four support feet 1043 extend to stabilize and level the device, while protecting the casters 1044 from damage due to long-term stress. The mounting brackets 1042 on both sides are fastened to the cabinet base plate 1041 to increase the stability of the test device of the cabinet air conditioner, and at the same time support the first cabinet air conditioner 201 and the second cabinet air conditioner 202.

[0072] like Figures 5a-5b As shown, under the operation of the EC blower 120, the air inside the cavity of the test device circulates. The low-temperature air from the first cabinet air conditioner 201 and the second cabinet air conditioner 202 enters the long strip-shaped air ducts on both sides from the air inlet at the bottom of the side air duct partition 110. It flows from bottom to top to the cavity of the EC blower 120. Under the forced convection of the EC blower 120, the low-temperature air is heated by the heating component 121 and becomes high-temperature air. It then flows to the cabinet air outlet through the flow equalization plate 122 and enters the first cabinet air conditioner 201 and the second cabinet air conditioner 202 through the air conditioner return air inlet. After the high-temperature air is cooled by the first cabinet air conditioner 201 and the second cabinet air conditioner 202, it is then circulated to the cavities on both sides of the middle partition 111 and finally enters the side air duct partition 110, thus forming a cycle.

[0073] This application provides a testing device for a cabinet air conditioner, the specific implementation steps of which are as follows:

[0074] S101: Prepare the cabinet for installing the test device. The test device includes a cabinet simulation enclosure 100, air duct partitions 110, middle partitions 111, air duct top plate 112, EC blower 120 (also referred to as an adjustable speed fan or adjustable speed EC fan), heating components 121 (adjustable heater and non-adjustable heater, where the heater can also be referred to as an electric heater), flow equalization plate 122, temperature sensor 123, electrical control box 130, handheld device 131, mounting bracket 1042, support feet 1043, and casters 1044. The dimensions and structure of the cabinet simulation enclosure 100 are the same as those of an actual communication base station or power distribution cabinet. The two sides of the cabinet simulation enclosure 100 are used to install cabinet air conditioners.

[0075] S102: Install rack air conditioners on both sides of rack simulation enclosure 100. Install two rack air conditioners on both sides of the rack simulation enclosure, ensuring that the air return vents and air supply vents of the rack air conditioners are connected to the internal space of the rack simulation enclosure.

[0076] S103: Connect power and control lines. Connect the power and control lines of the cabinet simulation box 100 and the cabinet air conditioner to the electrical control box 130 respectively. The electrical control box 130 controls the start / stop and operation mode of the cabinet simulation box 100 and the cabinet air conditioner through the control lines.

[0077] S104: Set test conditions. Simulate different load test conditions by controlling the speed of the adjustable EC blower 120 and the power of the adjustable heater.

[0078] S105: Start-up Test. Start the cabinet air conditioner via electrical control box 130, simultaneously controlling the adjustable speed EC fan 120 and the adjustable heater to begin the test. During the test, monitor the operating status and environmental parameters of the cabinet air conditioner in real time, and adjust the test conditions as needed.

[0079] S106: Data Recording and Analysis. After the test is completed, the test data is recorded, including the operating parameters, environmental parameters, and energy consumption of the rack air conditioner, and analyzed to evaluate the performance and reliability of the rack air conditioner. The rack air conditioner testing device provided in this embodiment of the application, by simulating a real application environment and flexibly adjusting the test conditions, can simultaneously test two rack air conditioners, record and analyze the test data, and thus more objectively evaluate the performance and reliability of the rack air conditioner.

[0080] It should be noted that in the master-slave linkage control mode, either the first cabinet air conditioner 201 or the second cabinet air conditioner 202 can be a master or a slave. For example, if the first cabinet air conditioner 201 is designated as the master, it is responsible for the main control decisions. The first cabinet air conditioner 201 can decide when to turn on or off the cooling function based on factors such as ambient temperature and humidity. As the master, the first cabinet air conditioner 201 is also responsible for sending instructions to the second cabinet air conditioner 202, which is the slave, to ensure the coordinated operation of the entire air conditioning system. If the second cabinet air conditioner 202 is designated as the slave, the second cabinet air conditioner 202 adjusts its own operating status according to the target parameters (such as target temperature, operating mode, etc.) set by the first cabinet air conditioner 201 to support the first cabinet air conditioner 201 in completing the overall temperature control task.

[0081] The test device for the rack air conditioner simulates different load test conditions by controlling the internal temperature of the rack simulation enclosure 100. Its control logic is as follows:

[0082] When the internal temperature of the cabinet simulation enclosure 100 is lower than the set value of the internal control temperature, the EC blower 120 runs at full speed. The heating component 121 first runs the non-adjustable heater according to the internal temperature. If the heating capacity of the non-adjustable heater is still insufficient to meet the test load requirements, the power of the adjustable heater is increased proportionally until the internal temperature equals the set value of the internal control temperature. The heating component 121 maintains the current power operation to achieve continuous and stable test conditions.

[0083] When the internal temperature of the cabinet simulation enclosure 100 is greater than the set value of the internal control temperature, the EC blower 120 runs at full speed. The heating component 121 first reduces the power of the adjustable heater according to the internal temperature. If the heating capacity of the adjustable heater is still insufficient to meet the test load requirements, the number of non-adjustable heaters is turned off to achieve the internal temperature equal to the set value of the internal control temperature. The heating component 121 maintains the current number of non-adjustable heaters to achieve continuous and stable test conditions.

[0084] When the internal temperature of the cabinet simulation enclosure 100 exceeds the set value of the high temperature alarm, the test device will automatically cut off the power input of the heating component 121, and the EC blower 120 will run at full speed to quickly cool down the internal temperature of the cabinet simulation enclosure 100 of the test device to prevent safety accidents.

[0085] Compared with existing testing methods for rack-mounted air conditioners, this application solves the problem that existing technologies cannot realistically reproduce the actual application environment of rack-mounted air conditioners. For example, existing testing devices can usually only be used in laboratory environments and cannot realistically reproduce the working environment of rack-mounted air conditioners in actual applications, such as outdoor high temperature, low temperature, and humidity environments. Furthermore, existing rack-mounted air conditioners are small in size and have relatively small cooling and heating capacities. Testing them through enthalpy difference laboratories or thermal balance laboratories is overkill, resulting in a waste of testing resources and reduced accuracy of test results. In contrast, this application can more realistically reproduce application scenarios. For example, the rack-mounted air conditioner testing device provided in this application can simulate the structure of outdoor cabinets such as communication base stations and power distribution units, thereby more objectively reproducing the application scenarios of rack-mounted air conditioners. At the same time, by achieving a year-round periodic operation testing environment, its testing conditions and results are more realistic. Compared with the shortcomings of existing technologies that can only be used in laboratory environments and cannot realistically reproduce the working environment of rack-mounted air conditioners in actual applications, this application is closer to actual applications and can provide more reliable test results.

[0086] Existing testing devices offer limited flexibility in adjusting operating conditions, failing to flexibly simulate diverse loads and environmental conditions. This restricts testing efficiency and accuracy. The rack air conditioner testing device proposed in this application offers significantly higher efficiency and flexibility: it employs an adjustable-speed EC fan and an adjustable heater, simulating various loads and allowing for more flexible adjustment of testing conditions, thus improving efficiency and conserving resources. Installing the EC fan and heating components at the top of the testing device ensures uniform return air temperature for the tested rack air conditioner, and aligns the airflow direction within the simulated rack enclosure with that of the rack air conditioner, minimizing the impact of airflow on the air conditioner within a limited space. Compared to existing technologies with their limited adjustment methods and inflexible simulation of different loads and environmental conditions, this application provides a more flexible testing approach, improving both efficiency and accuracy.

[0087] Existing testing devices typically only allow testing of one rack air conditioner, unable to test multiple rack air conditioners simultaneously or realistically simulate master-slave linkage control modes. This poses a significant limitation for verifying the linkage control logic of rack air conditioners. In contrast, the rack air conditioner testing device proposed in this application possesses comprehensive testing capabilities: it can simultaneously test two rack air conditioners for comparative testing and can realistically simulate master-slave linkage control modes for verifying the linkage control logic. Compared to existing technologies that can only test one rack air conditioner at a time and cannot realistically simulate master-slave linkage control modes, this application provides more comprehensive testing capabilities, facilitating the verification of rack air conditioner performance and reliability.

[0088] Existing testing devices typically lack waterproofing, failing to meet the requirements for long-term outdoor use. Furthermore, the input power of the control box may be incompatible with rack air conditioners operating under different power systems. In contrast, the rack air conditioner testing device proposed in this application boasts broad adaptability and compatibility: It employs a waterproof structural design, meeting the requirements for long-term outdoor use, and its control box is equipped with inputs for different power systems, accommodating testing of rack air conditioners with varying power systems. Compared to existing technologies that lack waterproofing and cannot meet the requirements for long-term outdoor use, and whose control box input power may be incompatible with rack air conditioners operating under different power systems, this application demonstrates broad adaptability and compatibility, improving the convenience and reliability of testing.

[0089] Existing testing devices typically lack the ability to move freely, making it inconvenient to switch between testing scenarios. However, the rack-mounted air conditioner testing device proposed in this application offers convenient mobility: it is equipped with casters, allowing for free movement and more convenient switching between testing scenarios. Compared to existing technologies, this application provides greater mobility, making testing more flexible and convenient.

[0090] Furthermore, the test device for the cabinet air conditioner in this application has been assembled and verified in operation. It is easy to assemble and maintain, the EC blower and heating components are well controlled, and all functions are operating normally, meeting the requirements of the test device for the cabinet air conditioner.

[0091] In summary, the rack air conditioner testing device provided in this application assembles rack air conditioners on the outer sides of the rack side panels 101 on opposite sides of the rack simulation enclosure 100. The air supply vents at the lower end of the rack air conditioners correspond to the rack air inlets at the lower end of the rack side panels 101, and the air return vents at the upper end of the rack air conditioners correspond to the rack air outlets at the upper end of the rack side panels 101. This testing device can simultaneously test two rack air conditioners for comparative testing and can also realistically simulate the master-slave linkage control mode; in a pair A partition 111 is installed in the middle of the interior of the side panels 101 of the cabinets on both sides to prevent the two air conditioners in the opposite cabinets from interfering with each other when supplying air to the interior of the cabinet simulation enclosure 100. Air duct partitions 110 are respectively installed on the inner sides of the side panels 101 of the other opposite cabinets of the cabinet simulation enclosure 100. The air duct partitions 110 and the other opposite side panels 101 together form the air ducts on both sides of the cabinet simulation enclosure 100. An air duct is also installed at the upper interior of the cabinet simulation enclosure 100. The top plate 112 has an EC blower 120 installed in the middle. Heating components 121 are installed on the side panels of the cabinet around the EC blower 120. A flow equalization plate 122 is installed below the EC blower 120, and a temperature sensor 123 is installed at the lower end of the flow equalization plate 122. The installation of these components inside the cabinet simulation box 100 allows for flexible simulation of different loads and environmental conditions, improving testing efficiency and saving testing resources. The casters 1044 installed at the lower end of the cabinet simulation box 100 allow the test device to move freely, making it easier to switch between test scenarios. The support feet 1043 installed at the lower end of the cabinet simulation box make the test device more stable when stationary. The test device adopts a waterproof structural design, which can meet the requirements for long-term outdoor use. At the same time, the electrical control box 130 is equipped with inputs of different electrical systems to meet the testing of cabinet air conditioners with different electrical systems. This allows the test device to adapt to various power supply voltages and frequencies, improving the versatility and flexibility of the test device.
