Description

Technical Field

[0001] This application relates to the field of chiller technology, such as a method and apparatus for controlling an air-suspended chiller, a chiller, and a computer-readable storage medium. Background Technology

[0002] Currently, with the increasing emphasis on energy conservation and emission reduction by the state, variable flow central air conditioning systems are being adopted. Typically, central air conditioning systems use water-cooled chillers as the main unit. Water-cooled chillers use constant flow heat exchangers as both evaporators and condensers. The flow rate of the water medium changes with the system load, affecting both the overall heat exchange efficiency and system energy consumption.

[0003] To ensure the stability of water flow velocity and improve the heat exchange efficiency of chiller units, a convertible flow heat exchanger is disclosed, comprising a shell, heat exchange tubes, a front tube sheet, a rear tube sheet, a front water chamber assembly, a rear water chamber assembly, an inlet, an outlet, a refrigerant gas interface, and a refrigerant liquid interface. The front and rear tube sheets are respectively attached to the two ends of the shell, and corresponding tube holes are provided on the front and rear tube sheets. The heat exchange tubes, connected to the corresponding tube holes, penetrate the shell. The refrigerant gas interface and the refrigerant liquid interface are connected to the interior of the shell. The interior of the heat exchange tubes is the tube-side space, where water entering the heat exchanger flows. The space between the heat exchanger and the shell is the shell-side space, where refrigerant entering the heat exchanger flows. The front water chamber assembly is fixed to one side of the front tube sheet, and the rear water chamber assembly is fixed to the other side of the rear tube sheet. The front water chamber assembly includes… The system comprises vertical diaphragms, horizontal diaphragms, and a front-flipped end cap. The vertical diaphragms divide the internal space between the front-flipped end cap and the front tube sheet into two sides from a vertical plane. One side is further divided into upper and lower sides by a horizontal diaphragm. The rear water chamber assembly includes a rear-flipped end cap and diaphragms. The diaphragms divide the internal space between the rear-flipped end cap and the rear tube sheet into upper and lower sides. The tube holes above the horizontal diaphragms on one side of the vertical diaphragms correspond to the heat exchange tube pass A, and the tube holes below the horizontal diaphragms correspond to the heat exchange tube pass D. The tube holes above the diaphragms on the other side of the vertical diaphragms correspond to the heat exchange tube pass B, and the tube holes below the diaphragms correspond to the heat exchange tube pass C. The A pass is connected to the inlet via valves A and F. The B and C passes are connected to the inlet via valves B and C, respectively. The D pass is connected to the outlet via valve D. Valves A and F are connected to the inlet via valve E. The above-mentioned heat exchanger is used as follows: When the water flow rate in the heat exchange tubes is small, open valves A, D, and F, and close valves B, C, and E. The heat exchanger is a four-pass heat exchanger; the hot water flows from the inlet through the D, C, B, and A passes and finally flows out from the outlet to exchange heat with the refrigerant in the shell-side space. When the water flow rate in the heat exchange tubes is large, open valves A, B, C, D, and E, and close valve F. The hot water flows from the inlet simultaneously from the D pass to the C pass. The heat exchanger is a two-pass heat exchanger, from the A-pass to the B-pass and finally flows out from the outlet to exchange heat with the refrigerant in the shell space. When it is necessary to reduce the heat exchange area, valves C and D are opened and valves A, B, E, and F are closed. The heat exchanger is a two-pass heat exchanger and the heat exchange tubes of the A-pass and B-pass are not working. Alternatively, valves A, B, and E are opened and valves C, D, and F are closed. The heat exchanger is a two-pass heat exchanger and the heat exchange tubes of the C-pass and D-pass are not working.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Related technologies regulate the heat exchange capacity by adjusting the overall heat exchange area of ​​the heat exchanger. However, the above-mentioned regulation method requires the synchronous control of multiple valves, which is complex in structure and cumbersome in control process, resulting in low efficiency in heat exchange capacity regulation.

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0031] Unless otherwise stated, the term "multiple" means two or more.

[0032] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0033] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0034] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0035] This disclosure provides an air-suspension chiller unit, including an evaporator 10, a condenser, and an air-suspension compressor connected in sequence.

[0036] Combination Figure 1 and Figure 2 As shown, the evaporator 10 includes an inlet end cap 10a, an outlet end cap 10b, and a partition plate 101. The inlet end cap 10a is connected to the first heat exchange tube section 102 of the evaporator. The outlet end cap 10b is connected to the second heat exchange section 103. One end of the partition plate 101 is fixedly disposed on the inner wall of the evaporator 10, and the other end is disposed at the separation point between the first heat exchange tube section 102 and the second heat exchange tube section 103. The first heat exchange tube section 102 is configured as a first flow path, and the second heat exchange tube section 103 is configured as a second flow path.

[0037] Optionally, multiple position markers L1, L2...L are arranged sequentially at intervals from the partition to the inlet seal 10a. nn is an integer greater than or equal to 2. L1 is located on the axis of symmetry of the evaporator. Where L2, ..., L... n They are all located in the middle position between the two heat exchange tubes of the heat exchange tube section.

[0038] Thus, by adjusting the arrangement position of the other end of the partition plate 101, the number of heat exchange tubes in the first heat exchange tube section 102 and the second heat exchange tube section 103 can be dynamically adjusted, thereby realizing the dynamic adjustment of the heat exchange area of ​​the first process and the second process.

[0039] Based on the above-mentioned air-suspended chiller unit, combined with Figure 3 As shown in the embodiments of this disclosure, a control method for an air-suspended chiller unit is provided, including:

[0040] S01, in cooling mode, the outlet water temperature of the air suspension chiller is obtained.

[0041] S02, the air suspension chiller unit adjusts the position of the partition plate according to the outlet water temperature to adjust the heat exchange area of ​​the first heat exchange tube section and the second heat exchange tube section respectively.

[0042] The control method for air-suspended chiller units provided in this disclosure, in cooling mode, acquires the outlet water temperature of the air-suspended chiller unit and adjusts the position of the partition plate according to the outlet water temperature to adjust the heat exchange area of ​​the first and second heat exchange tube sections. In cooling mode, when the outlet water temperature is different, the heat exchange capacity of the first and second processes is different, and the heat exchange difficulty of the first and second processes is unequal. This disclosure, by adjusting the position of the partition plate, can achieve a non-uniform distribution of the number of heat exchange tubes in the first and second processes, achieving a balance between the heat exchange capacity and the heat exchange difficulty of the first and second processes, which is beneficial to improving the energy efficiency of the air-suspended chiller unit. Furthermore, this disclosure does not adjust the overall heat exchange area of ​​the evaporator, but only adjusts the heat exchange capacity of the first and second processes. The heat exchange capacity can be adjusted by adjusting the end position of the partition plate, without the need for simultaneous control of multiple valves. The structure is simple and highly controllable, which is beneficial to improving the heat exchange capacity adjustment efficiency.

[0043] Optionally, the air-suspended chiller unit adjusts the position of the baffle plate according to the outlet water temperature to adjust the heat exchange area of ​​the first heat exchange tube section, including:

[0044] The air-suspended chiller selects the target location from multiple location markers based on the correspondence between the outlet water temperature value and the location value.

[0045] The other end of the control partition of the air-suspended chiller unit moves to the target position.

[0046] In this way, the embodiment of the present disclosure pre-stores the correspondence between the outlet water temperature value and the position value, and selects the target position from the plurality of position tables according to the above correspondence. Then the other end of the split partition is controlled to move to the target position. In this way, the respective heat exchange amounts of the first process and the second process can be dynamically adjusted according to the level of the outlet water temperature value, so as to achieve the effect of balancing the respective heat exchange amounts and the respective heat exchange difficulty degrees of the first process and the second process, improve the heat exchange amount adjustment efficiency, and facilitate the improvement of the energy efficiency of the air suspension unit.

[0047] It should be noted that the correspondence between the outlet water temperature value and the position value may be: pre-storing the correspondence between the temperature range and the position value. The correspondence between the outlet water temperature value and the position value is determined according to the matching situation between the outlet water temperature value and the temperature range and the above correspondence.

[0048] Optionally, the selecting, by the air-suspended water chiller, the target position from the plurality of position identifiers according to the correspondence between the outlet water temperature value and the position value includes:

[0049] In the case that T0≤T<T1, the air-suspended water chiller selects L1 as the target position.

[0050] In the case that T1≤T<T2, the air-suspended water chiller selects L2 as the target position.

[0051] In the case that T2≤T<T3, the air-suspended water chiller selects L3 as the target position.

[0052] Wherein, T represents the outlet water temperature value, T0 represents the reference temperature threshold, T1 represents the first temperature threshold, T2 represents the second temperature threshold, and T3 represents the third temperature threshold.

[0053] In this way, the embodiment of the present disclosure can dynamically adjust the respective heat exchange amounts of the first process and the second process according to the level of the outlet water temperature value, so as to achieve the effect of balancing the respective heat exchange amounts and the respective heat exchange difficulty degrees of the first process and the second process, improve the heat exchange amount adjustment efficiency, and facilitate the improvement of the energy efficiency of the air suspension unit.

[0054] In a specific example, 2°C≤T0≤5°C, 16°C≤T3≤20°C. Preferably, T0=3°C, T3=18°C.

[0055] It can be understood that the above three target positions are schematic positions. In specific applications, the air-suspended water chiller can further subdivide the range of the outlet water temperature value, and set different position values corresponding to the subdivided ranges.

[0056] Optionally, in combination with Figure 4 as shown, the controlling, by the air-suspended water chiller, the other end of the split partition to move to the target position includes:

[0057] S11, the other end of the adjustable partition of the air suspension chiller unit moves to the target position and continues for a first duration t1.

[0058] S12, the air-suspended chiller unit re-acquires a new outlet water temperature value T′.

[0059] S13, in T i ≤T′ <T i+1 In this case, the other end of the control partition of the air-suspended chiller unit is controlled by L i Move to L i+1 .

[0060] Where i is a positive integer less than or equal to n-1.

[0061] Thus, after the other end of the baffle plate in this embodiment of the present disclosure is moved to the target position and held for a first duration t1, the new outlet water temperature value tends to stabilize. At this time, this embodiment of the present disclosure re-acquires a new outlet water temperature value T′, and at T... i ≤T′ <T i+1 At that time, in this embodiment of the present disclosure, the other end of the control partition is controlled by L i Move to L i+1 This reduces the number of first heat exchange tubes in the first process to decrease the heat exchange capacity of the first process, and increases the number of second heat exchange tubes in the second process to increase the heat exchange capacity of the second process. This enables dynamic adjustment of the heat exchange capacity of the first and second processes, improves the heat exchange capacity adjustment efficiency, and helps to improve the energy efficiency of the air suspension unit.

[0062] Optionally, the partition plate has deformable properties. As an example, the partition plate is made of a flexible material.

[0063] In this way, when the other end of the partition plate moves, its shape changes due to the deformation characteristics of the partition plate, ensuring that the heat exchange medium water does not flow directly from the inlet end cap side from the first heat exchange tube section to the second heat exchange tube section, thereby improving the reliability of heat exchange regulation. While improving the energy efficiency of the air suspension unit, it also ensures the safety and reliability of the air suspension unit operation.

[0064] Combination Figure 5As shown in the figure, this disclosure provides a control device 200 for an air-suspended chiller unit. The evaporator includes an inlet end cap, an outlet end cap, and a partition plate. The inlet end cap is connected to a first heat exchange tube section of the evaporator, and the outlet end cap is connected to a second heat exchange tube section. One end of the partition plate is fixedly disposed on the inner wall of the evaporator, and the other end is disposed at the separation point between the first and second heat exchange tube sections. The device 200 includes an acquisition module 201 and a control module 202. The acquisition module 201 is configured to acquire the outlet water temperature value of the air-suspended chiller unit in cooling mode. The control module 202 is configured to adjust the position of the partition plate according to the outlet water temperature value to adjust the heat exchange area of ​​the first and second heat exchange tube sections respectively.

[0065] The device 200 for controlling an air-suspended chiller unit provided in this embodiment can achieve a non-uniform distribution of the number of heat exchange tubes in the first and second processes by adjusting the position of the partition plate. This balances the heat exchange capacity and the ease of heat exchange in the first and second processes, improves the heat exchange capacity regulation efficiency, and helps to improve the energy efficiency of the air-suspended chiller unit.

[0066] Optionally, the control device for the air-suspended chiller unit further includes a position adjustment device. The position adjustment device, located at the other end of the split partition, is configured to controllably adjust the position of the other end of the split partition.
