[0002] A multi-day refrigerant-based water-based air conditioning system is essentially a combined central air conditioning system that integrates a refrigerant-based central air conditioning system with a water-based underfloor heating system. The entire system has two independent circulation systems: refrigerant and water, providing both cooling and heating functions to meet the needs of summer cooling and winter heating. The underfloor heating system includes water pipes with valves that control the water flow. For example, when the underfloor heating is needed in heating mode, the valves open to allow water to flow; when it is not needed, the valves close to stop the water flow.
[0003] In the process of implementing the embodiments of this disclosure, it was found that at least the following problems exist in the related technology: directly controlling the power supply of the floor heating valve without determining the valve type used may cause the floor heating to fail to operate normally.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.
[0006] This disclosure provides a detection method and apparatus for an air conditioning system, an air conditioning system, and a storage medium to correctly activate the underfloor heating valve so that the underfloor heating of the air conditioning system can provide normal heating.
[0007] In some embodiments, a detection method for an air conditioning system includes:
[0008] When the underfloor heating is in heating mode, power on the underfloor heating valve.
[0009] The valve type for the underfloor heating system is determined based on its operation. Valve types include normally open valves and normally closed valves.

[0013] In some embodiments, after determining that the underfloor heating valve is a normally open valve in the event of abnormal operation of the underfloor heating system, the method further includes:
[0014] Power off the control valve for the underfloor heating system;
[0015] The valve type for the underfloor heating system should be determined again based on the system's operation.
[0016] In some embodiments, the valve type of the underfloor heating valve is determined again based on the operation of the underfloor heating system, including:

[0018] If the underfloor heating system is malfunctioning, it indicates that the system has broken down.
[0019] In some embodiments, after determining that the underfloor heating valve is a normally closed valve under normal operating conditions, the method further includes:
[0020] Power off the control valve for the underfloor heating system;
[0021] The valve type for the underfloor heating system should be determined again based on the system's operation.
[0022] In some embodiments, the valve type of the underfloor heating valve is determined again based on the operation of the underfloor heating system, including:
[0023] In the event of abnormal operation of the underfloor heating system, determine that the underfloor heating valve is a normally closed valve.
[0024] In some embodiments, after determining the valve type of the underfloor heating valve again based on the operation of the underfloor heating system, the method further includes:
[0025] Store the valve type of the underfloor heating valve in the outdoor unit of the air conditioner;
[0026] In the subsequent heating mode of the underfloor heating system, the power on or off of the underfloor heating valve is controlled according to the valve type to ensure the normal operation of the underfloor heating system.
[0027] In some embodiments, operating conditions include at least one of: water flow rate in the water line, compressor discharge temperature, or condensing pressure of the outdoor heat exchanger.
[0028] In some embodiments, a detection device for an air conditioning system includes a processor and a memory storing program instructions, the processor being configured to execute the above-described detection method for an air conditioning system when the program instructions are executed.

[0030] In some embodiments, the storage medium stores program instructions that, when executed, perform any of the above-described detection methods for an air conditioning system.
[0031] The detection method and apparatus for air conditioning systems, air conditioning systems, and storage media provided in this disclosure can achieve the following technical effects: In an air conditioning system with an air conditioner and underfloor heating, when the underfloor heating is in heating mode, the underfloor heating valve is forcibly energized by controlling it. Then, based on the operation of the underfloor heating, it can be determined whether the underfloor heating valve is a normally open valve or a normally closed valve. This allows the air conditioning system to be energized or de-energized according to the valve type of the underfloor heating valve, so that the underfloor heating valve can be connected when the underfloor heating is in heating mode, and the underfloor heating can operate normally.

[0047] Combination Figure 1 As shown, the air conditioning system includes an air conditioner and underfloor heating. The air conditioner includes an indoor unit and an outdoor unit connected by refrigerant piping. The indoor unit includes an indoor heat exchanger 410 and an indoor fan. The outdoor unit includes a shell-and-tube heat exchanger 420, an outdoor heat exchanger 430, an outdoor fan, a compressor 440, and a four-way valve. Refrigerant flows between the indoor and outdoor units through refrigerant piping 450, forming a refrigerant circulation path. The underfloor heating system includes a water tank 310, a water pump 320, and water piping 330, extending from the indoor unit to the outdoor unit. The shell-and-tube heat exchanger 420 includes a first flow path and a second flow path that can exchange heat. The first flow path is connected to the underfloor heating water piping 330 and contains water, while the second flow path is connected to the refrigerant piping 450 and contains refrigerant. Heat exchange can occur between the refrigerant in the air conditioner and the water in the underfloor heating system. A floor heating valve is installed on the water pipe. When the floor heating valve is turned on, the water in the water pipe can flow so that the floor heating can exert its heating effect.
[0048] When the underfloor heating system is in heating mode, the refrigerant circulation in the outdoor unit is as follows: The compressor discharges high-temperature, high-pressure gaseous refrigerant, which passes through a four-way valve into the shell-and-tube heat exchanger. There, it exchanges heat with the water flowing through the heat exchanger and condenses into liquid refrigerant. The liquid refrigerant then passes through the outdoor unit's electronic expansion valve into the outdoor heat exchanger, where it evaporates back into gaseous refrigerant. The gaseous refrigerant then flows back to the compressor, completing the cycle. The underfloor heating system's water pump operates, and water flows from the tank to the shell-and-tube heat exchanger. After absorbing heat in the heat exchanger, the water flows back into the room.
[0049] Combination Figure 2 As shown, this disclosure provides a testing method for an air conditioning system, including:
[0050] S10, when the underfloor heating is in heating mode, the control device controls the underfloor heating valve to be powered on.
[0051] S20, the control device determines the valve type of the underfloor heating valve according to the operation of the underfloor heating system. The valve types include normally open valves and normally closed valves.
[0052] In step S10, when the underfloor heating is in heating mode, if the underfloor heating valve can connect to the water pipe, the underfloor heating can operate normally and provide heating. If the underfloor heating valve fails to connect to the water pipe, the underfloor heating will operate abnormally and will not be able to provide normal heating.
[0053] In step S20, after the floor heating valve is forcibly powered on, the floor heating system may operate normally or abnormally depending on the type of the valve. The control device can determine the specific type of the floor heating valve based on the operating status of the floor heating system.
[0054] Underfloor heating valves come in two types: normally open and normally closed. A normally open valve operates by being in the on state when power is off, allowing water to flow normally in the pipes; when power is on, the valve is in the off state, preventing water flow. A normally closed valve operates by being in the off state when power is off, preventing water flow; when power is on, the valve is in the on state, allowing water to flow.
[0055] In step S20, the control device can determine the valve type of the underfloor heating valve based on its operation status 30 minutes after powering it on. In this way, after 30 minutes of operation, the relevant parameters of the underfloor heating system can more accurately reflect the valve type.
[0056] The detection method provided in this embodiment can, in an air conditioning system including an air conditioner and underfloor heating, force the underfloor heating valve to power on when the underfloor heating is in heating mode. Then, based on the operation of the underfloor heating, it can determine whether the valve type of the underfloor heating valve is a normally open valve or a normally closed valve. This allows the air conditioning system to power on or off according to the valve type of the underfloor heating valve, so that the underfloor heating valve can be normally connected and the underfloor heating can operate normally when the underfloor heating is in heating mode.
[0057] In some embodiments, operating conditions include at least one of: water flow rate in the water line, compressor discharge temperature, or condensing pressure of the outdoor heat exchanger.
[0058] When the underfloor heating system is operating normally, the water flow rate in the water pipes, the compressor's exhaust temperature, and the outdoor heat exchanger's condensing pressure are all within normal ranges. When the underfloor heating system is operating abnormally, at least one of these parameters will deviate significantly from the normal value. Therefore, it is possible to determine whether the underfloor heating system is operating normally based on at least one of these parameters.
[0059] Optionally, the operation status of underfloor heating can be determined in the following ways:
[0060] The control device obtains the actual flow rate of water in the water pipeline, the actual discharge temperature of the compressor, or the actual condensing pressure of the outdoor heat exchanger;
[0061] If the absolute value of the difference between the actual flow rate and the preset flow rate is greater than the first preset value, or the absolute value of the difference between the actual exhaust temperature and the preset temperature is greater than the second preset value, or the absolute value of the difference between the actual condensing pressure and the preset pressure is greater than the third preset value, the control device determines that the floor heating is malfunctioning.
[0062] In this way, by observing the changes in one of the above parameters before and after power-on, it can be determined whether the underfloor heating is malfunctioning.
[0063] Optionally, the operation status of underfloor heating can be determined in the following ways:
[0064] The control device acquires at least two of the following: the actual flow rate of water in the water pipeline, the actual discharge temperature of the compressor, and the actual condensing pressure of the outdoor heat exchanger;
[0065] If at least two of the following conditions are met: the absolute value of the difference between the actual flow rate and the preset flow rate is greater than a first predetermined value; the absolute value of the difference between the actual exhaust temperature and the preset temperature is greater than a second predetermined value; and the absolute value of the difference between the actual condensing pressure and the preset pressure is greater than a third predetermined value, the control device determines that the floor heating system is malfunctioning.
[0066] In this way, it is possible to determine whether the underfloor heating is malfunctioning based on the changes in at least two parameters before and after power-on, resulting in a more accurate assessment.
[0067] Optionally, the control device determines the valve type of the underfloor heating valve based on the operation of the underfloor heating system, including:
[0068] When the underfloor heating is operating normally, the control device determines that the underfloor heating valve is a normally closed valve.
[0069] In the event of abnormal operation of the underfloor heating system, the control device determines that the underfloor heating valve is normally open.
[0070] In this embodiment, after the floor heating valve is powered on, if the floor heating system operates normally, it indicates that the floor heating valve is in the on state when powered on, and should be in the off state when powered off. Therefore, the type of the floor heating valve is a normally closed valve. If the floor heating system operates abnormally, it indicates that the floor heating valve is in the off state when powered on, and should be in the on state when powered off. Therefore, the type of the floor heating valve is a normally open valve.
[0071] This embodiment of the invention can determine whether the type of the underfloor heating valve is a normally open valve or a normally closed valve by observing the operation of the underfloor heating system. This allows the control device to subsequently control the valve to be powered on or off based on its type, so that the underfloor heating system can function properly for heating.
[0072] Combination Figure 3 As shown, this disclosure provides another detection method for an air conditioning system, including:
[0073] S10, when the underfloor heating is in heating mode, the control device controls the underfloor heating valve to be powered on.
[0074] S21, the control device determines whether the floor heating is operating normally. If yes, then proceed to step S31; otherwise, proceed to step S32.
[0075] S31, the control device determines that the floor heating valve is a normally closed valve.
[0076] S32, the control device determines that the floor heating valve is a normally open valve.
[0077] Using the detection method provided in this embodiment, in the case of underfloor heating operation in heating mode, the underfloor heating valve is forcibly powered on by controlling it, and the valve type of the underfloor heating valve can be determined based on the operation status of the underfloor heating. This allows the control device to control whether the valve is powered on or off according to its type during subsequent underfloor heating operation, so that the underfloor heating can perform its heating function normally.
[0078] In some embodiments, after the control device determines that the underfloor heating valve is a normally open valve in the event of abnormal operation of the underfloor heating system, it further includes:
[0079] The control device cuts off the power to the floor heating valve.
[0080] The control device then determines the valve type of the underfloor heating valve based on the operation of the underfloor heating system.
[0081] In this embodiment of the disclosure, if the floor heating system operates abnormally after the control device forces the floor heating valve to power on, it may be due to a fault in the floor heating system, in addition to the floor heating valve being a normally open valve being disconnected due to power-on. Therefore, the control device controls the floor heating valve to power off, and judges the valve type of the floor heating valve again based on the floor heating system operation after the power is off, so as to avoid misjudging the valve type of the floor heating valve.
[0082] In this embodiment of the disclosure, after the control device controls the floor heating valve to power off for 30 minutes, the valve type of the floor heating valve is determined again based on the operation of the floor heating system. This makes the determination of the floor heating valve type more accurate.
[0083] The detection method provided in this embodiment, after determining that the floor heating valve is a normally open valve, further controls the floor heating valve to be powered off, and judges the valve type of the floor heating valve again based on the subsequent operation of the floor heating system, so as to accurately determine the valve type of the floor heating valve.
[0084] In some embodiments, the control device further determines the valve type of the underfloor heating valve based on the operation of the underfloor heating system, including:
[0085] When the underfloor heating is operating normally, the control device determines that the underfloor heating valve is a normally open valve.
[0086] If the underfloor heating system malfunctions, the control device will determine that the underfloor heating system has failed.
[0087] In this embodiment, if the underfloor heating system operates normally after the power to the control valve is turned off, it indicates that the valve is indeed a normally open valve. A normally open valve remains in the on state after power is turned off, enabling the underfloor heating system to operate normally. If the underfloor heating system still operates abnormally after the power to the control valve is turned off, it indicates that there is a malfunction in the underfloor heating system, causing it to malfunction regardless of whether the power is on or off. In this case, it cannot be concluded that the underfloor heating valve is definitely a normally open valve.
[0088] The detection method provided in this embodiment can further verify the valve type after initially determining that the floor heating valve is a normally open valve. After two judgments, the valve type of the floor heating valve can be accurately determined, and the fault of the floor heating can be detected in time, avoiding misjudgment of the valve type of the floor heating valve.
[0089] Combination Figure 4 As shown, this disclosure provides another detection method for an air conditioning system, including:
[0090] S10, when the underfloor heating is in heating mode, the control device controls the underfloor heating valve to be powered on.
[0091] S21, the control device determines whether the floor heating is operating normally. If yes, then proceed to step S31; otherwise, proceed to step S32.
[0092] S31, the control device determines that the floor heating valve is a normally closed valve.
[0093] S32, the control device determines that the floor heating valve is a normally open valve, and then executes step S40.
[0094] S40, the control device controls the power off of the floor heating valve.
[0095] S50, the control device again determines whether the floor heating is operating normally. If yes, then proceed to step S61; otherwise, proceed to step S62.
[0096] S61, the control device determines that the floor heating valve is a normally open valve.
[0097] S62, the control device has determined that the underfloor heating system has malfunctioned.
[0098] The detection method provided in this embodiment of the invention can forcibly power on the underfloor heating valve when the underfloor heating system is in heating mode. It determines whether the valve is a normally open or normally closed valve based on the operating status of the underfloor heating system. If the valve is initially determined to be normally open, the valve type is further verified. By making two determinations, it is clear whether the valve is indeed normally open or if there is a malfunction in the underfloor heating system, thus avoiding misjudgment of the valve type. This allows the control device to accurately power on or off the underfloor heating valve according to its valve type, ensuring that the valve is properly connected and the underfloor heating system operates normally in heating mode.
[0099] In some embodiments, after the control device determines that the underfloor heating valve is a normally closed valve when the underfloor heating is operating normally, it further includes:
[0100] The control device cuts off the power to the floor heating valve.
[0101] The control device then determines the valve type of the underfloor heating valve based on the operation of the underfloor heating system.
[0102] In this embodiment, after determining that the underfloor heating valve is a normally closed valve, the control device can also de-energize the underfloor heating valve and re-determine its valve type based on the operation of the underfloor heating system. This two-step determination ensures accurate identification of the valve type, avoiding misjudgments.
[0103] In some embodiments, the control device further determines the valve type of the underfloor heating valve based on the operation of the underfloor heating system, including:
[0104] In the event of abnormal operation of the underfloor heating system, the control device determines that the underfloor heating valve is normally closed.
[0105] In this embodiment, after the control device powers on the floor heating valve for the first time, the floor heating system operates normally, indicating that there is no fault in the system and confirming that the valve is a normally closed valve. Then, when the control device de-powers the valve, it should become open, indicating an abnormal operation. In this case, the abnormal operation is caused by the valve's state, not a fault in the system itself. Furthermore, after secondary verification, it can be accurately confirmed that the valve is indeed a normally closed valve.
[0106] Combination Figure 5 As shown, this disclosure provides another detection method for an air conditioning system, including:
[0107] S10, when the underfloor heating is in heating mode, the control device controls the underfloor heating valve to be powered on.
[0108] S21, the control device determines whether the floor heating is operating normally. If yes, then proceed to step S33; otherwise, proceed to step S34.
[0109] S33, the control device determines that the floor heating valve is a normally closed valve, and then executes step S41.
[0110] S34, the control device determines that the floor heating valve is a normally open valve.
[0111] S41, the control device controls the floor heating valve to de-energize.
[0112] S50, in the event of abnormal operation of the underfloor heating system, the control device determines that the underfloor heating valve is a normally closed valve.
[0113] The detection method provided in this embodiment can rule out the possibility of a malfunction in the underfloor heating system and can accurately determine whether the underfloor heating valve is a normally closed valve.
[0114] In some embodiments, after the control device determines the valve type of the underfloor heating valve again based on the operation of the underfloor heating system, the system further includes:
[0115] The control device stores the valve type of the underfloor heating valve in the outdoor unit of the air conditioner.
[0116] In the subsequent heating mode of the underfloor heating system, the control device controls the power supply to or off of the underfloor heating valve according to the valve type of the underfloor heating valve, so that the underfloor heating system can operate normally.
[0117] The detection method provided in this embodiment can store the valve type of the underfloor heating valve in the outdoor unit of the air conditioner. When the underfloor heating system subsequently operates in heating mode, the control device controls the valve to be powered on or off according to the valve type, ensuring that the valve can connect to the water pipe in heating mode, allowing water to flow and thus enabling the underfloor heating system to function properly. Specifically, after the control device determines that the underfloor heating valve is a normally closed valve, it stores this information in the computer board of the outdoor unit. When the underfloor heating system subsequently operates in heating mode, the control device directly powers on the valve, thus connecting the water flow and allowing the underfloor heating system to operate normally. Similarly, after determining that the underfloor heating valve is a normally open valve, the control device stores this information in the computer board of the outdoor unit. When the underfloor heating system subsequently operates in heating mode, the control device directly powers off the valve, thus connecting the water flow and allowing the underfloor heating system to operate normally.
[0118] Combination Figure 6As shown, this embodiment of the disclosure provides a detection device 200 for an air conditioning system, including a control module 21 and a determination module 22. The control module 21 is configured to control the power supply of the underfloor heating valve when the underfloor heating is in heating mode; the determination module 22 is configured to determine the valve type of the underfloor heating valve based on the operation of the underfloor heating system. The valve type includes normally open valves and normally closed valves.
[0119] The detection device for air conditioning systems provided in this embodiment can determine the valve type of the floor heating valve through the cooperation of the control module 21 and the determination module 22. This allows the control device to power on or off the floor heating valve according to its valve type during subsequent operation of the floor heating system, so that the floor heating valve can start correctly when the floor heating system is in heating mode.
[0120] Combination Figure 7 As shown, this embodiment of the present disclosure provides a detection device 300 for an air conditioning system, including a processor 100 and a memory 101. Optionally, the device may further include a communication interface 102 and a bus 103. The processor 100, communication interface 102, and memory 101 can communicate with each other via the bus 103.
