[0045] Referring to the drawings Figure 1 Figure 1 FIG. 1 is a schematic diagram of the main steps of a control method of a water air conditioner according to an embodiment of the present application. As shown in FIG. 1, the water inlet of the water air conditioner is provided with a first temperature sensor, and the water outlet of the water air conditioner is provided with a second temperature sensor. The control method of the water air conditioner mainly includes the following steps S101-S102. Figure 1

[0046] Step S101: obtaining the water inlet temperature through the first temperature sensor and obtaining the water outlet temperature through the second temperature sensor.

[0047] In this embodiment, the water inlet temperature of the water air conditioner is obtained through the first temperature sensor, and the water outlet temperature of the water air conditioner is obtained through the second temperature sensor.

[0048] In one embodiment, the first temperature sensor can be a thermistor sensor.

[0049] In one embodiment, the second temperature sensor can be a thermistor sensor.​​​

[0050] In one embodiment, the water air conditioner can draw underground water through a water pump, and rely on the underground water to adjust the temperature of an evaporator in the main unit of the water air conditioner, thereby realizing the refrigeration function or the heating function.

[0051] Step S102: In response to the water air conditioner being turned on for the first time or being turned on at intervals for a preset time length, obtaining fault information of the water air conditioner based on the inlet water temperature and the outlet water temperature, to determine the fault of the first temperature sensor and / or the second temperature sensor according to the fault information.

[0052] In this embodiment, when the water air conditioner is turned on for the first time or is turned on at intervals for a preset time length, the fault information of the water air conditioner is obtained according to the inlet water temperature and the outlet water temperature, and then the fault of the first temperature sensor and / or the second temperature sensor is determined according to the fault information.

[0053] In one embodiment, the preset time length can be six months.

[0054] In one embodiment, the fault information of the water air conditioner can be a fault code.

[0055] In one embodiment, the fault information includes first fault information and second fault information, and step S102 can include the following steps S1021 to S1023:

[0056] Step S1021: Determine whether the absolute value of the difference between the inlet water temperature and the outlet water temperature at the current time is less than or equal to a first preset temperature, if not, execute step S1022, if yes, execute step S1023.

[0057] Step S1022: Determine that the fault information is the first fault information and the second fault information.

[0058] Step S1023: Obtain the fault information of the water air conditioner based on the operating mode of the water air conditioner, the inlet water temperature and the outlet water temperature.

[0059] In this embodiment, it is determined whether the absolute value of the difference between the inlet water temperature and the outlet water temperature at the current time is less than or equal to a first preset temperature, if not, it is determined that the fault information is the first fault information and the second fault information. If yes, the fault information of the water air conditioner is obtained based on the operating mode of the water air conditioner, the inlet water temperature and the outlet water temperature. Wherein, the first fault information indicates that the first temperature sensor and the second temperature sensor exist in the condition of reverse insertion; the second fault information indicates that the first temperature sensor and / or the second temperature sensor exist in the condition of virtual insertion.

[0060] After the installation of the first temperature sensor and / or the second temperature sensor, the thermal insulation cotton needs to be pasted, and if the thermal insulation cotton is pasted incorrectly, it will cause virtual insertion.

[0061] In one embodiment, the absolute value of the difference between the inlet water temperature and the outlet water temperature of the water air conditioner is generally not more than 2 degrees Celsius in a normal state when the water air conditioner is just started. If the absolute value of the difference between the inlet water temperature and the outlet water temperature of the water air conditioner exceeds 2 degrees Celsius, it indicates that the first temperature sensor and / or the second temperature sensor is faulty. Therefore, the first preset temperature can be 2 degrees Celsius.

[0062] In one embodiment, step S1023 can include steps S102301 to S102303.

[0063] Step S102301: If the operation mode is the cooling mode and the inlet water temperature and the outlet water temperature at the current time are both greater than or equal to the second preset temperature, the water air conditioner is controlled to run for a first preset time length, and then the inlet water temperature and the outlet water temperature at the current time are acquired again.

[0064] Step S102302: If the difference between the outlet water temperature and the inlet water temperature at the current time is less than or equal to a third preset temperature, the fault information is determined to be first fault information.

[0065] Step S102303: If the difference between the outlet water temperature and the inlet water temperature at the previous time is greater than a fourth preset temperature, the fault information is determined to be second fault information.

[0066] In the embodiment, if the operation mode is the cooling mode and the inlet water temperature and the outlet water temperature at the current time are both greater than or equal to the second preset temperature, the water air conditioner is controlled to run for a first preset time length, and then the inlet water temperature and the outlet water temperature at the current time are acquired again. If the difference between the inlet water temperature and the outlet water temperature at the current time is less than or equal to the third preset temperature, the fault information is determined to be first fault information. If the difference between the inlet water temperature and the outlet water temperature at the previous time is greater than the fourth preset temperature, the fault information is determined to be second fault information. The water air conditioner is controlled to run for a first preset time length, and then the inlet water temperature and the outlet water temperature at the current time are acquired again, so as to ensure the relative stability of the inlet water temperature and the outlet water temperature.

[0067] In one embodiment, in the cooling mode, the difference between the outlet water temperature and the inlet water temperature of the water air conditioner in a normal operation is greater than zero. If the difference between the outlet water temperature and the inlet water temperature is less than or equal to zero, it indicates that the first temperature sensor at the water inlet of the water air conditioner and the second temperature sensor at the water outlet are in a reverse insertion state. Therefore, the third preset temperature can be 0 degrees Celsius.

[0068] In one embodiment, in the refrigeration mode, if the first temperature sensor of the water inlet of the air conditioner and / or the second temperature sensor of the water outlet are inserted reversely, the values measured by the first temperature sensor and / or the second temperature sensor will be larger than the actual values, and the difference between the outlet water temperature and the inlet water temperature will be larger. Therefore, the fourth preset temperature can be 5 degrees Celsius.

[0069] In one embodiment, the first preset time length can be 30 minutes.

[0070] In one embodiment, the second preset temperature can be 16 degrees Celsius.

[0071] In one embodiment, the step S1023 can include the following steps S102304 and S102305:

[0072] In the step S102304, if the operation mode of the water air conditioner is the refrigeration mode, and the outlet water temperature and the inlet water temperature at the current time are both greater than or equal to the fifth preset temperature and less than the second preset temperature, the water air conditioner is controlled to run for the first preset time length, and then the outlet water temperature and the inlet water temperature at the current time are acquired again.

[0073] In the step S102305, if the difference between the outlet water temperature and the inlet water temperature at the current time is less than or equal to the sixth preset temperature, the fault information is determined as the first fault information.

[0074] In the embodiment, if the operation mode of the water air conditioner is the refrigeration mode, and the outlet water temperature and the inlet water temperature at the current time are both greater than or equal to the fifth preset temperature and less than the second preset temperature, the water air conditioner is controlled to run for the first preset time length, and then the outlet water temperature and the inlet water temperature at the current time are acquired again. If the difference between the outlet water temperature and the inlet water temperature at the current time is less than or equal to the sixth preset temperature, the fault information is determined as the first fault information.

[0075] In one embodiment, in the refrigeration mode, since the outlet water temperature and the inlet water temperature fluctuate greatly in the range of greater than or equal to -5 degrees Celsius and less than 16 degrees Celsius, the difference between the outlet water temperature and the inlet water temperature of the water air conditioner in the normal operation is generally greater than -1 degree Celsius. If the difference between the outlet water temperature and the inlet water temperature is less than or equal to -1 degree Celsius, it indicates that the first temperature sensor of the water inlet and the second temperature sensor of the water outlet of the water air conditioner are inserted reversely. Therefore, the third preset temperature can be -1 degree Celsius, and the fifth preset temperature can be -5 degrees Celsius.

[0076] In one embodiment, the step S1023 can include the following steps S102306 to S102308:

[0077] Step S102306: If the operation mode of the water air conditioner is the heating mode, and the inlet water temperature and the outlet water temperature at the current time are both greater than a seventh preset temperature and less than or equal to an eighth preset temperature, the water air conditioner is controlled to run for a first preset time length, and then the inlet water temperature and the outlet water temperature at the current time are acquired again.

[0078] Step S102307: If the difference between the inlet water temperature and the outlet water temperature at the current time is less than or equal to a third preset temperature, the fault information is determined to be first fault information.

[0079] Step S102308: If the difference between the inlet water temperature and the outlet water temperature at the current time is greater than a fourth preset temperature, the fault information is determined to be second fault information.

[0080] In the embodiment, if the operation mode of the water air conditioner is the heating mode, and the inlet water temperature and the outlet water temperature at the current time are both greater than a seventh preset temperature and less than or equal to an eighth preset temperature, the water air conditioner is controlled to run for a first preset time length, and then the inlet water temperature and the outlet water temperature at the current time are acquired again. If the difference between the inlet water temperature and the outlet water temperature at the current time is less than or equal to a third preset temperature, the fault information is determined to be first fault information. If the difference between the inlet water temperature and the outlet water temperature at the current time is greater than a fourth preset temperature, the fault information is determined to be second fault information.

[0081] In one embodiment, the seventh preset temperature can be seven degrees Celsius.

[0082] In one embodiment, the eighth preset temperature can be twenty degrees Celsius.

[0083] In one embodiment, in the heating mode, the difference between the inlet water temperature and the outlet water temperature when the water air conditioner is normally running is greater than zero. If the difference between the inlet water temperature and the outlet water temperature is less than or equal to zero, it indicates that the first temperature sensor at the water inlet and the second temperature sensor at the water outlet of the water air conditioner are inserted reversely. Therefore, the third preset temperature can be zero degrees Celsius.

[0084] In one embodiment, in the heating mode, if the first temperature sensor at the water inlet and / or the second temperature sensor at the water outlet of the air conditioner are inserted reversely, it will cause the values measured by the first temperature sensor and / or the second temperature sensor to be larger than the actual values, and further cause the difference between the outlet water temperature and the inlet water temperature to be larger. Therefore, the fourth preset temperature can be five degrees Celsius.

[0085] In one embodiment, step S1023 can include the following steps S102309 to S102311:

[0086] Step S102309: If the operation mode of the water air conditioner is the heating mode, and the inlet water temperature and the outlet water temperature at the current time are both greater than the ninth preset temperature and less than or equal to the seventh preset temperature, the water air conditioner is controlled to run for a first preset time length, and then the inlet water temperature and the outlet water temperature at the current time are acquired again.

[0087] Step S102310: If the difference between the inlet water temperature and the outlet water temperature at the current time is less than or equal to the sixth preset temperature, the fault information is determined to be the first fault information.

[0088] Step S102311: If the difference between the inlet water temperature and the outlet water temperature at the current time is greater than or equal to the third preset temperature and less than or equal to the tenth preset temperature, the compressor of the water air conditioner is controlled to run at a preset frequency for a second preset time length, and then the inlet water temperature and the outlet water temperature at the current time are acquired again. If the difference between the inlet water temperature and the outlet water temperature at the current time is less than or equal to the tenth preset temperature, the fault information is determined to be the first fault information. If the difference between the inlet water temperature and the outlet water temperature at the current time is greater than the fourth preset temperature, the fault information is determined to be the second fault information.

[0089] In the embodiment, if the operation mode of the water air conditioner is the heating mode, and the inlet water temperature and the outlet water temperature at the current time are both greater than the ninth preset temperature and less than or equal to the seventh preset temperature, the water air conditioner is controlled to run for a first preset time length, and then the inlet water temperature and the outlet water temperature at the current time are acquired again. If the difference between the inlet water temperature and the outlet water temperature at the current time is less than or equal to the sixth preset temperature, the fault information is determined to be the first fault information. If the difference between the inlet water temperature and the outlet water temperature at the current time is greater than or equal to the third preset temperature and less than or equal to the tenth preset temperature, the compressor of the water air conditioner is controlled to run at a preset frequency for a second preset time length, and then the inlet water temperature and the outlet water temperature at the current time are acquired again. If the difference between the inlet water temperature and the outlet water temperature at the current time is less than or equal to the tenth preset temperature, the fault information is determined to be the first fault information. If the difference between the inlet water temperature and the outlet water temperature at the current time is greater than the fourth preset temperature, the fault information is determined to be the second fault information.

[0090] In one embodiment, in the heating mode, because the outlet water temperature and the inlet water temperature exist large fluctuations in the range of greater than or equal to negative thirty degrees Celsius and less than seven degrees Celsius, the difference between the inlet water temperature and the outlet water temperature when the water air conditioner is normally running is generally greater than negative one degree Celsius. If the difference between the inlet water temperature and the outlet water temperature is less than or equal to negative one degree Celsius, it indicates that the first temperature sensor at the water inlet of the water air conditioner and the second temperature sensor at the water outlet exist the condition of being inserted reversely. Therefore, the third preset temperature can be negative one degree Celsius, and the ninth preset temperature can be negative thirty degrees Celsius.

[0091] In one embodiment, in the heating mode, if the difference between the inlet water temperature and the outlet water temperature of the water air conditioner when the water air conditioner is normally running is greater than zero degrees Celsius and less than or equal to one degree Celsius, the compressor of the water air conditioner is controlled to increase the frequency and run for a second preset time length, then the inlet water temperature and the outlet water temperature at the current time are obtained again, according to the working principle of the compressor increasing the frequency, the difference between the inlet water temperature and the outlet water temperature is generally in the range of greater than one degree Celsius and less than five degrees Celsius. If the difference between the inlet water temperature and the outlet water temperature is less than or equal to one degree Celsius, it indicates that the first temperature sensor and the second temperature sensor are inserted reversely. If the difference between the inlet water temperature and the outlet water temperature is greater than five degrees Celsius, it indicates that the first temperature sensor and / or the second temperature sensor is inserted virtually.

[0092] In one embodiment, the second preset time length can be twenty minutes.

[0093] In one embodiment, the preset frequency can be eighty percent of the maximum frequency of the compressor.

[0094] Based on the above steps S101-S102, the present application obtains the inlet water temperature through the first temperature sensor and obtains the outlet water temperature through the second temperature sensor. In response to the water air conditioner being started for the first time or being started for an interval of a preset time length, based on the inlet water temperature and the outlet water temperature, the fault information of the water air conditioner is obtained to determine the fault of the first temperature sensor and / or the second temperature sensor according to the fault information. Through the above configuration, the present application can determine the fault information of the water air conditioner only through the inlet water temperature and the outlet water temperature, and then determine the fault of the first temperature sensor and / or the second temperature sensor according to the fault information. The accurate troubleshooting of the sensors affecting the frequency operation of the compressor of the water air conditioner is realized without increasing the hardware cost.
