[0050] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0051] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, inside, outside, top, bottom...) are only used to explain the relative position relationship between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0052] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, the element may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0053] See also Figures 1 to 3 A temperature control device provided by an embodiment of the present invention is used in scenarios such as data centers that contain a large number of heat sources and require heat dissipation, such as computer rooms, to adjust the temperature in the computer room to prevent the temperature in the computer room from being too high and affecting the normal operation of electrical components such as internal servers.

[0054] In one embodiment, the temperature control device is an air conditioner, and the specific type of the air conditioner is not limited, such as a variable frequency air conditioner. The air conditioner includes a compressor, a condenser, an evaporator, a pipeline assembly, a joint, and a control module. The compressor and the condenser, the condenser and the evaporator, and the evaporator and the compressor are connected through the pipeline assembly, respectively, so that the refrigerant can circulate between the compressor, the condenser, and the evaporator. The control module is used to control the rotation of the joint, so as to install the joint on the pipeline assembly or remove it from the pipeline assembly to reduce manual operation.

[0055] The specific manner in which the control module controls the rotation of the joint is not limited. For example, a motor connected to the joint may be provided, and the control module controls the shaft of the motor to rotate, thereby driving the joint to rotate, so as to complete the installation and removal of the joint.

[0056] In one embodiment, the condenser is located outdoors, serving as the outdoor unit of the air conditioner, and the compressor and the evaporator are located indoors, serving as the indoor unit of the air conditioner. Universal wheels are provided at the bottom of the indoor unit, and the universal wheels have a locked state and an unlocked state. When the indoor unit needs to be moved, the universal wheels can be in an unlocked state to facilitate the transfer of the indoor unit. After the indoor unit is moved to the corresponding position, the universal wheels are switched from the unlocked state to the locked state to reduce the risk of movement of the indoor unit during operation.

[0057] The number of connectors is preferably two, and the two connectors include a first connector and a second connector. The first connector is close to the outlet of the indoor unit, and the second connector is close to the inlet of the indoor unit. The outlet of the indoor unit is connected to the inlet of the outdoor unit, and the inlet of the indoor unit is connected to the outlet of the outdoor unit. The first connector is located between the outlet of the indoor unit and the inlet of the outdoor unit, and the second connector is located between the outlet of the outdoor unit and the inlet of the indoor unit. When the first connector and the second connector are respectively installed to the pipeline assembly, the indoor unit of the air conditioner can be connected to the outdoor unit. When the first connector and the second connector are removed from the pipeline assembly, the indoor unit of the air conditioner can be separated from the outdoor unit, and the indoor unit can be transferred to other positions through the universal wheels.

[0058] It should be noted that when the first joint and the second joint are removed from the pipe assembly, it means that the first joint and the second joint are removed from the pipe connected to the condenser, thereby disconnecting from the condenser. At this time, the first joint and the pipe connected to the compressor and the second joint and the pipe connected to the evaporator still remain in a fixed connection state.

[0059] The first joint is close to the outlet of the compressor, and the second joint is close to the inlet of the compressor. Specifically, the first joint is located between the compressor and the condenser, and the second joint is located between the condenser and the evaporator.

[0060] It should be noted that the first joint is close to the outlet of the compressor and the second joint is close to the inlet of the compressor, which means that in the process of the refrigerant circulating between the compressor, the condenser and the evaporator, along the flow direction of the refrigerant, the first joint is closer to the outlet of the compressor than the second joint, and the second joint is closer to the inlet of the compressor than the first joint, so that after the refrigerant is discharged from the outlet of the compressor, it first passes through the first joint, then passes through the second joint, and then flows into the compressor from the inlet of the compressor.

[0061] The first connector and the second connector are respectively provided with valves, such as solenoid valves. The control module can control the opening, closing and opening degree of the valves. When the valves in the first connector and the second connector are both opened, the refrigerant can circulate between the compressor, the condenser and the evaporator. When the first connector is closed, the refrigerant in the compressor can no longer flow to the condenser. When the second connector is closed, the refrigerant in the condenser can no longer flow to the evaporator. By integrating the valve and the connector together, the connector has both the functions of connection and valve, which can control the connection and separation of the indoor unit and the outdoor unit, and control the flow and flow of the refrigerant, enriching the functions of the connector, reducing the use of the same components, and making after-sales maintenance relatively simple.

[0062] Preferably, the control module can be powered separately, so that the control module can be used when the thermostat is powered off. When the thermostat needs to be powered off due to installation or removal, the power supply can be used to power the control module separately, so that the control module can work normally when the thermostat is powered off. Under the premise of ensuring the safety of the assembly and disassembly operation, the normal operation of the control module is not affected, and the convenience of operation is improved.

[0063] The control module may include one or more controllers. When the control module includes one controller, the controller can control both the rotation of the joint and the on-off of the valve; when the control module includes multiple controllers, some controllers are used to control the rotation of the joint, and some controllers are used to control the on-off of the valve.

[0064] See also Figure 1 An embodiment of the present invention provides a method for controlling the assembly and disassembly of a temperature control device. The control method is applied to the temperature control device in the above embodiment, and a control module of the temperature control device is used to execute the control method; the control method includes:

[0065] Step 11: Receive installation instructions.

[0066] Step 12: according to the installation instruction, the automatic installation mode is started, and a first screwing control instruction for controlling the rotation of the joint is issued, and the joint rotates in a direction of being tightened to the connecting pipeline according to the first screwing control instruction.

[0067] The connector and the connecting pipeline are threaded together, so they can be fixedly connected or disconnected by rotation. Under the action of the first screwing control instruction, the connector rotates in the direction of fixed connection between the connector and the connecting pipeline. The connecting pipeline refers to the pipeline in the pipeline assembly used to connect to the connector.

[0068] Step 13: Obtain the precession torque parameters of the joint during the rotation process.

[0069] Step 14: Determine whether the joint installation currently meets the safe installation conditions based on the screw-in torque parameter.

[0070] Each specification of connector has a corresponding torque range, so a preset range corresponding to the connector specification can be set in advance. Based on the comparison result of the acquired screw-in torque parameter with the preset range, it can be determined whether the acquired screw-in torque parameter has an abnormality. For example, when the screw-in torque parameter is within the preset range, it is determined that the screw-in torque parameter is normal, and then it is determined that the connector installation meets the safe installation conditions. When the screw-in torque parameter is not within the preset range, it is determined that the screw-in torque parameter is abnormal, and then it is determined that the connector installation does not meet the safe installation conditions.

[0071] Step 15: If the safety installation condition is met, the joint is controlled to rotate through the first screwing control instruction until the joint is screwed into a preset position.

[0072] Satisfying the safety installation conditions means that the connector is correctly connected to the connecting pipeline and there is no abnormality between the connector and the connecting pipeline, so the first screwing control instruction is continuously issued, and the connector continues to rotate under the action of the first screwing control instruction until the connector is screwed into the preset position, completing the assembly of the connector and the connecting pipeline. Specifically, the preset position is a preset sealing position, and after the connector is screwed into the preset sealing position, a sealing effect is formed between the connector and the connecting pipeline to prevent leakage.

[0073] Step 16: If the safety installation condition is not met, a screw stop command is issued to control the joint to stop rotating.

[0074] Failure to meet the safe installation conditions indicates that there is an abnormal condition between the connector and the connecting pipe. Continuing the installation may affect the quality after installation or even cause damage to the connector or the connecting pipe outlet. Therefore, if it is determined that the safe installation conditions are not met, a screw stop command is issued to control the connector to stop rotating and stop the installation of the connector.

[0075] The connector can automatically rotate in the direction of tightening to the connecting pipe according to the first screwing control instruction, which can reduce manual operation, reduce the impact of space on installation operation, and reduce manual errors, thereby reducing after-sales costs caused by manual errors; and during the rotation of the connector, the screw-in torque parameter of the connector can be obtained, and the screw-in torque parameter can be used to determine whether the current installation of the connector meets the safe installation conditions. If the safe installation conditions are met, the connector is controlled to continue rotating to complete the installation. If the safe installation conditions are not met, the connector is controlled to stop rotating to avoid affecting the installation quality and reduce the risk of damage to the connector and the connecting pipe during the installation process.

[0076] In one embodiment, receiving the installation instruction includes:

[0077] Under the condition that the connector is pre-installed to the connecting pipeline, the installation instruction is obtained based on the operation received through the button of the operation interface.

[0078] During the installation of the connector, the operator can first screw the threaded end of the connector into the connecting pipe to form a preliminary alignment and connection effect, complete the pre-installation of the connector, and then input the installation instructions through the buttons on the operation interface. After the control module receives the installation instructions, it controls the connector to start the automatic installation mode.

[0079] In one embodiment, after issuing a screwing stop instruction to control the joint to stop rotating, the method further includes:

[0080] A prompt message is issued to indicate that an abnormality exists between the connector and the connected pipe.

[0081] When it is determined that the safety installation conditions are not met, the control module first controls the joint to stop rotating, and then issues a prompt message on the operation interface to remind the operator that there is an abnormality between the joint and the connecting pipeline, for example, the joint is not aligned with the connecting pipeline, the joint or the connecting pipeline is blocked by foreign objects, etc., so that the operator can promptly know that the joint currently does not meet the safety installation conditions, so as to conduct timely troubleshooting and re-enter the installation instructions through the operation interface after troubleshooting; and the joint has stopped rotating before the prompt message is issued, so the operator does not need to manually control the joint to stop rotating, thereby reducing the risk of increasing the difficulty of troubleshooting due to excessive screwing of the joint.

[0082] It can be understood that the prompt information can be a prompt voice, or a prompt text, or a prompt light, etc., as long as it can have the effect of reminding the operator.

[0083] In one embodiment, after the joint is screwed into a preset position, the method further comprises:

[0084] Determine whether the valve opening conditions are met.

[0085] If the opening conditions are met, the valve in the control joint opens.

[0086] If the opening condition is not met, it enters the standby state, and after receiving the opening command of the valve, the valve in the control joint is opened.

[0087] After the joint is installed, first determine whether the opening conditions of the valve are met. When the opening conditions are met, open the valve in the joint to allow the refrigerant to flow in the temperature control device, so that the temperature control device can enter the working state and play a role in regulating the temperature. When the opening conditions are not met, do not open the valve first, and put the joint into the standby state first. When the operator determines that the temperature control device can operate normally, input the opening command to control the valve to avoid opening the valve when the joint is installed but other components of the temperature control device are not installed, which may cause refrigerant leakage.

[0088] Preferably, after determining that the valve opening condition is met or receiving an opening instruction, the control module controls the opening of the valve in the joint to be fully open, so that the refrigerant flows more smoothly in the temperature control device.

[0089] When the joint is installed and the valve is opened, the normal opening operation of the temperature control equipment can be completed, such as vacuuming and pressure maintenance. During the normal operation of the temperature control equipment, the control module is connected to the power supply of the temperature control equipment, and no separate power supply is required. The control module is connected to the alarm system of the temperature control equipment to coordinate the alarm. The control module always maintains the last state of the joint and valve set in the operation interface.

[0090] In order to have a more comprehensive understanding of the installation process of the temperature control device disassembly and assembly control method provided in the embodiment of the present application, please refer to Figure 2 , the temperature control equipment disassembly and assembly control method includes:

[0091] Step 21: Power on the control module.

[0092] Step 22: Receive installation instructions.

[0093] Step 23: A first screwing control instruction is issued, and the connector rotates in a direction of being screwed to the connection pipeline according to the first screwing control instruction.

[0094] Step 24: Obtain the screw-in torque parameter of the joint during the rotation process;

[0095] Step 25: Determine whether the precession torque parameter is within a preset range; if so, execute step 261; if not, execute step 262.

[0096] Step 261: The control joint is screwed into a preset sealing position.

[0097] Step 27: It is indicated that the connector has been installed in place, and it is determined whether the valve opening condition is met; if so, step 281 is executed; if not, step 282 is executed.

[0098] Step 281: Control the valve in the joint to be fully open.

[0099] Step 282: Enter standby mode.

[0100] Step 29: After receiving the opening command of the valve, the opening of the valve in the control joint is fully opened.

[0101] Step 262: Control the joint to stop rotating.

[0102] Step 30: A prompt message is issued to indicate that an abnormality exists between the connector and the connecting pipeline.

[0103] In one embodiment, the temperature control device disassembly and assembly control method further includes:

[0104] Obtain repair and maintenance instructions.

[0105] When the temperature control equipment needs to be reconnected, moved, repaired, or maintained, the operator can input the repair and maintenance instructions through the operation interface, and the control module can obtain the repair and maintenance instructions.

[0106] Determine whether refrigerant recovery is required according to the inspection and maintenance instructions;

[0107] When it is determined that the refrigerant needs to be recovered, the compressor of the temperature control device is controlled to continue to run, and the valve of the first joint close to the compressor outlet is closed.

[0108] When the compressor continues to run and the valve of the first joint is closed, the refrigerant can still flow in the piping assembly, but because the valve of the first joint has been closed, the refrigerant in the compressor can no longer flow to the condenser, while the refrigerant in the condenser can still flow to the evaporator to recover the refrigerant in the outdoor unit of the temperature control equipment to the indoor unit.

[0109] Determine the flow state of the refrigerant on the condensing side of the temperature control device, and determine whether the valve of the second joint close to the compressor inlet meets the closing requirement based on the flow state.

[0110] The flow state of the refrigerant on the condensing side is the flow state of the refrigerant at the condenser. When the refrigerant flows from the condenser to the evaporator, it means that part of the refrigerant is still in the outdoor unit, and it is determined that the valve of the second joint does not meet the closing condition. When no refrigerant flows from the condenser to the evaporator, it means that the refrigerant has been fully or nearly fully recovered to the indoor unit, and it is determined that the valve of the second joint meets the closing condition.

[0111] The specific method of determining the flow state is not limited. For example, it can be determined by detecting the flow rate of the refrigerant in the condenser. When the flow rate is zero or basically zero, it means that the refrigerant in the condenser has basically flowed into the evaporator, thereby determining that the valve of the second joint meets the closing requirement; or, it can be determined by detecting the temperature of the condenser. When the refrigerant in the condenser gradually decreases, the temperature of the condenser will also gradually decrease. When the temperature of the condenser is reduced to a certain range, it can be determined that the refrigeration parts in the condenser have basically flowed into the evaporator, thereby determining that the valve of the second joint meets the closing requirement.

[0112] If the closing requirements are met, the valve of the second joint is controlled to close and the compressor stops running.

[0113] After the valves of the first joint and the second joint are closed, the refrigerant can no longer flow out from the valves of the first joint and the second joint, so the refrigerant is contained in the compressor and the evaporator.

[0114] If the closing requirement is not met, the flow state of the refrigerant on the condensing side of the temperature control device is obtained again, and it is determined whether the valve of the second joint close to the compressor inlet meets the requirement according to the flow state.

[0115] When it is determined that the refrigerant needs to be recovered, the compressor is controlled to continue running and the valve of the first joint is closed, so that the refrigerant in the compressor cannot flow to the condenser, while the refrigerant in the condenser can still flow to the evaporator. When it is determined that no refrigerant flows from the condenser to the evaporator, the valve of the second joint is closed to store the refrigerant in the compressor and evaporator. The joint can assist in completing the refrigerant recovery operation, which is conducive to reducing the cumbersomeness of the operation and enhancing the interactive experience.

[0116] Specifically, when the compressor is running, the indoor fan corresponding to the evaporator and the outdoor fan corresponding to the condenser are running normally. After the refrigerant is recovered, the compressor stops running, and the indoor fan and the outdoor fan also stop running.

[0117] In one embodiment, determining the flow state of the refrigerant on the condensing side of the temperature control device includes:

[0118] The coil temperature on the condensing side is obtained, and the flow state of the refrigerant on the condensing side of the temperature control device is determined according to the coil temperature.

[0119] When the refrigerant flows in the condenser, it passes through the condenser coil. Since the temperature of the refrigerant passing through the coil is high, the temperature of the coil is also relatively high. As the refrigerant in the coil decreases, the temperature of the coil will drop accordingly. Therefore, the temperature of the coil can be used to determine the condition of the refrigerant inside it, and then determine the flow state of the refrigerant.

[0120] It can be understood that the coil temperature can be obtained by a temperature sensor, and the flow state of the refrigerant can be determined based on the coil temperature. The coil temperature can be compared with a preset temperature value or temperature range to determine the flow state. Alternatively, the difference between the coil temperature and the set or obtained temperature value can be obtained, and the flow state can be determined based on the difference.

[0121] In one embodiment, obtaining the coil temperature on the condensing side and determining the flow state of the refrigerant on the condensing side of the temperature control device according to the coil temperature include:

[0122] Get the return air temperature on the condensing side, and get the flow state based on the difference between the coil temperature and the return air temperature.

[0123] The return air temperature on the condensing side refers to the ambient temperature where the condenser is located. Specifically, under the action of the outdoor fan, the air near the condenser will form an airflow and pass through the condenser. The return air temperature refers to the air temperature when the airflow does not exchange heat with the coil. When the return air temperature is the same or substantially the same as the coil temperature, it can be determined that all or nearly all of the refrigerant in the coil has flowed into the evaporator. By obtaining the return air temperature in real time, the flow state is determined based on the difference between the return air temperature and the coil temperature to avoid the influence of the ambient temperature on the accuracy of the result.

[0124] Specifically, when the difference between the coil temperature and the return air temperature does not exceed 3° C., it is determined that the valve of the second joint meets the closing requirement.

[0125] In one embodiment, if the closing requirement is met, controlling the valve of the second connector to close and the compressor to stop running includes:

[0126] When it is determined that the closing requirement is met, the valve of the second joint is controlled to remain open for a preset time and then closed, and the compressor continues to run for a preset time and then stops running.

[0127] When it is determined that the shutdown requirements are met, the return air temperature and the coil temperature are not necessarily completely equal. The difference between the two may be caused by the residual heat of the coil or a small amount of refrigerant remaining in the coil. Therefore, when the shutdown requirements are met, the compressor is controlled to continue to run for a preset time before stopping, and the valve of the second joint is controlled to remain open for a preset time before closing, leaving a certain amount of time for the refrigeration parts remaining in the condenser to flow into the evaporator, thereby improving the effect of recovering the refrigerant. At the same time, during this period of time, the refrigerant in the evaporator can flow into the compressor, thereby storing the refrigerant in the compressor. Specifically, the preset time is 5s.

[0128] In one embodiment, after the valve of the second joint is controlled to be closed and the compressor stops running, the method further includes:

[0129] Determine whether the first connector and the second connector need to be removed from the connecting pipeline;

[0130] When it is determined that the first joint and the second joint need to be removed from the connecting pipeline, a second screwing control instruction for controlling the rotation of the first joint and the second joint is issued, and the first joint and the second joint are synchronously rotated according to the second screwing control instruction until they are out of thread engagement with the connecting pipeline;

[0131] When it is determined that the first connector and the second connector do not need to be removed from the connecting pipeline, the system enters a standby state.

[0132] When the temperature control equipment does not need to be moved or the pipeline does not need to be changed, and the first joint and the second joint do not need to be removed during inspection or maintenance, you can choose not to remove the first joint and the second joint. Only when it is necessary to remove the first joint and the second joint, you can avoid the problem of needing to reinstall after removal. Moreover, when the first joint and the second joint need to be removed, they can be rotated synchronously to disengage the threaded fit, which can reduce the time required to remove the first joint and the second joint.

[0133] It can be understood that the control module issues a second screwing control instruction to control the rotation of the first joint and the second joint, which may mean that the first joint and the second joint rotate under the same instruction, or it may mean that the control module issues two different instructions at the same time, and the first joint and the second joint rotate respectively under the corresponding instructions.

[0134] In another embodiment, when it is determined that the first connector and the second connector need to be removed from the connecting pipeline, a second screwing control instruction is issued to control the rotation of the first connector and the second connector, and the first connector and the second connector are rotated successively according to the second screwing control instruction until they are out of threaded engagement with the connecting pipeline.

[0135] The first joint and the second joint are rotated successively to disengage the threaded engagement with the connecting pipe, thereby preventing the first joint and the second joint from interfering with each other during the rotation process and affecting the disassembly of the first joint and the second joint.

[0136] It should be noted that the first connector and the second connector are rotated successively to disengage the threaded fit with the connecting pipe according to the second screwing control instruction. The first connector can be controlled to rotate to disengage the threaded fit with the connecting pipe first, and then the second connector is controlled to rotate to disengage the threaded fit with the connecting pipe; or, the second connector can be controlled to rotate to disengage the threaded fit with the connecting pipe first, and then the first connector is controlled to rotate to disengage the threaded fit with the connecting pipe.

[0137] It can be understood that the first joint and the second joint rotate successively under the second screwing control instruction. The control module may issue an instruction containing a sequence, and the first joint and the second joint rotate successively under the action of the instruction. Alternatively, the control module may issue two different control instructions successively, and the first joint and the second joint rotate respectively under the corresponding instructions.

[0138] In one embodiment, the temperature control device disassembly and assembly control method further includes:

[0139] When it is determined that there is no need to recover the refrigerant, the valve of the first joint and the valve of the second joint are controlled to be closed and the compressor stops running.

[0140] After the compressor stops running and the valves of the first joint and the second joint are closed, the refrigerant cannot circulate between the indoor unit and the outdoor unit of the temperature control device, that is, the refrigerant in the compressor cannot flow to the condenser, and the refrigerant in the condenser can no longer flow to the evaporator.

[0141] Determine whether the first connector and the second connector need to be removed from the connecting pipeline.

[0142] When it is determined that the first connector and the second connector need to be removed from the connecting pipeline, a second screwing control instruction is issued to control the rotation of the first connector and the second connector, and the first connector and the second connector are synchronously rotated according to the second screwing control instruction until they are threadedly disengaged from the connecting pipeline, or the first connector and the second connector are rotated successively according to the second screwing control instruction until they are threadedly disengaged from the connecting pipeline.

[0143] Determine whether it is necessary to open the valves of the first connector and the second connector; if so, control the valve of the first connector and the valve of the second connector to open and discharge the refrigerant; if not, enter the standby state.

[0144] When it is determined that the first connector and the second connector do not need to be removed from the connecting pipeline, the system enters a standby state.

[0145] When the first joint and the second joint are rotated to be out of threaded engagement with the connecting pipe, it can be determined whether the refrigerant is suitable for discharge according to the position of the indoor unit. When the position is suitable for discharge of refrigerant, the valves of the first joint and the second joint are controlled to open to discharge the refrigerant; when the position is not suitable for discharge of refrigerant, the first joint and the second joint are controlled to enter a standby state, and then the indoor unit is transferred to a position suitable for discharge of refrigerant for discharge. Specifically, when the valves of the first joint and the second joint are controlled to open to discharge the refrigerant, the valves are controlled to open slowly to 10%.

[0146] In order to have a more comprehensive understanding of the disassembly process of the temperature control device disassembly and assembly control method provided in the embodiment of the present application, please refer to Figure 3 , the temperature control equipment disassembly and assembly control method includes:

[0155] Step 471: Control the first joint and the second joint to rotate synchronously, or control the first joint and the second joint to rotate successively, until the first joint and the second joint are both retreated to the starting point of the thread segment.

[0156] When the first joint and the second joint are withdrawn to the starting point of the threaded section, the first joint and the second joint just break away from the threaded fit with the connecting pipeline.

[0157] Step 472: Enter standby mode.

[0158] Step 422: Control the valve of the first connector and the valve of the second connector to close and stop the compressor.

[0159] Step 48: Determine whether the first connector and the second connector need to be removed from the connecting pipeline; if so, execute step 491; if not, execute step 492.

[0160] Step 491: Control the first joint and the second joint to rotate synchronously, or control the first joint and the second joint to rotate successively, until the first joint and the second joint are both retreated to the starting point of the thread segment.

[0161] Step 50: Determine whether the valves of the first connector and the second connector need to be opened; if so, execute step 511; if not, execute step 512.
