[0044] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart showing the main steps of a method for controlling a water air conditioner according to an embodiment of the present invention. Figure 1 As shown, the water inlet of the water air conditioner in the embodiment of the present invention is provided with a first temperature sensor, the water outlet of the water air conditioner is provided with a second temperature sensor, and the control method of the water air conditioner mainly includes the following steps S101-step S102.

[0045] Step S101: obtaining the water inlet temperature through the first temperature sensor, and obtaining the water outlet temperature through the second temperature sensor.

[0046] In this embodiment, the water inlet temperature of the water air conditioner is obtained by the first temperature sensor, and the water outlet temperature of the water air conditioner is obtained by the second temperature sensor.

[0047] In one embodiment, the first temperature sensor may be a thermistor sensor.

[0048] In one embodiment, the second temperature sensor may be a thermistor sensor.

[0049] In one embodiment, the water air conditioner can extract groundwater through a water pump, and rely on the groundwater to adjust the temperature of the evaporator in the water air conditioner main unit, thereby achieving a cooling function or a heating function.

[0050] Step S102: In response to the water conditioner being turned on for the first time or being turned on after a preset time interval, fault information of the water conditioner is obtained based on the water inlet temperature and the water outlet temperature to determine the fault of the first temperature sensor and / or the second temperature sensor according to the fault information.

[0051] In this embodiment, when the water air conditioner is turned on for the first time or after a preset interval, fault information of the water air conditioner is obtained based on 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 based on the fault information.

[0052] In one implementation, the preset interval length may be six months.

[0053] In one implementation, the fault information of the water air conditioner may be a fault code.

[0054] In one implementation, the fault information includes first fault information and second fault information, and step S102 may include the following steps S1021 to S1023:

[0055] Step S1021: Determine whether the absolute value of the difference between the current water inlet temperature and the water outlet temperature is less than or equal to the first preset temperature. If not, execute step S1022; if so, execute step S1023.

[0056] Step S1022: determine whether the fault information is the first fault information or the second fault information.

[0057] Step S1023: Based on the operation mode, water inlet temperature and water outlet temperature of the water air conditioner, the fault information of the water air conditioner is obtained.

[0058] 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 moment is less than or equal to the first preset temperature. If not, the fault information is determined to be the first fault information and the second fault information. If so, the fault information of the water air conditioner is obtained based on the operation mode, the inlet water temperature and the outlet water temperature of the water air conditioner. The first fault information indicates that the first temperature sensor and the second temperature sensor are plugged in reverse; the second fault information indicates that the first temperature sensor and / or the second temperature sensor are plugged in dummy.

[0059] After the first temperature sensor and / or the second temperature sensor are installed, thermal insulation cotton needs to be pasted. If the thermal insulation cotton is pasted incorrectly, false insertion will occur.

[0060] In one embodiment, when the water conditioner just starts to operate, under normal conditions, the absolute value of the difference between the water inlet temperature of the water conditioner and the water outlet temperature of the water conditioner generally does not exceed two degrees Celsius. If the absolute value of the difference between the water inlet temperature of the water conditioner and the water outlet temperature of the water conditioner exceeds two degrees Celsius, it indicates that the first temperature sensor and / or the second temperature sensor is faulty. Therefore, the first preset temperature may be two degrees Celsius.

[0061] In one implementation, step S1023 may include the following steps S102301 to S102303:

[0062] Step S102301: If the operation mode is cooling mode and the current water inlet temperature and water outlet temperature are both greater than or equal to the second preset temperature, the water air conditioner is controlled to run for the first preset time, and then the current water inlet temperature and water outlet temperature are obtained again.

[0063] Step S102302: If the difference between the current water outlet temperature and the water inlet temperature is less than or equal to the third preset temperature, the fault information is determined to be the first fault information.

[0064] Step S102303: If the difference between the outlet water temperature and the inlet water temperature at the previous moment is greater than the fourth preset temperature, the fault information is determined to be the second fault information.

[0065] In this embodiment, if the operation mode is the cooling mode and the water inlet temperature and the water outlet temperature at the current moment are both greater than or equal to the second preset temperature, the water inlet temperature and the water outlet temperature at the current moment are obtained again after the water air conditioner is controlled to operate for the first preset time. If the difference between the water inlet temperature and the water outlet temperature at the current moment is less than or equal to the third preset temperature, the fault information is determined to be the first fault information. If the difference between the water inlet temperature and the water outlet temperature at the previous moment is greater than the fourth preset temperature, the fault information is determined to be the second fault information. Among them, the water inlet temperature and the water outlet temperature at the current moment are obtained again after the water air conditioner is controlled to operate for the first preset time in order to ensure the relative stability of the water inlet temperature and the water outlet temperature.

[0066] In one embodiment, in the cooling mode, the difference between the outlet water temperature and the inlet water temperature of the water air conditioner during 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 means that the first temperature sensor at the water inlet and the second temperature sensor at the water outlet of the water air conditioner are plugged in reverse. Therefore, the third preset temperature may be zero degrees Celsius.

[0067] In one embodiment, in cooling mode, if the first temperature sensor at the water inlet and / or the second temperature sensor at the water outlet of the air conditioner is not plugged in, the value measured by the first temperature sensor and / or the second temperature sensor will be larger than the actual value, thereby causing the difference between the water inlet temperature and the water outlet temperature to be larger. Therefore, the fourth preset temperature may be five degrees Celsius.

[0068] In one implementation, the first preset duration may be thirty minutes.

[0069] In one embodiment, the second preset temperature may be sixteen degrees Celsius.

[0070] In one implementation, step S1023 may include the following steps S102304 to S102305:

[0071] Step S102304: If the operating mode of the water air conditioner is cooling mode and the current water outlet temperature and water inlet temperature are both greater than or equal to the fifth preset temperature and less than the second preset temperature, then control the water air conditioner to run for the first preset time, and then obtain the current water inlet temperature and water outlet temperature again.

[0072] Step S102305: If the difference between the current water outlet temperature and the water inlet temperature is less than or equal to the sixth preset temperature, the fault information is determined to be the first fault information.

[0073] In this embodiment, if the operation mode of the water air conditioner is the cooling mode and the outlet water temperature and the inlet water temperature at the current moment 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 operate for the first preset time, and the inlet water temperature and the outlet water temperature at the current moment are obtained again. If the difference between the outlet water temperature and the inlet water temperature at the current moment is less than or equal to the sixth preset temperature, the fault information is determined to be the first fault information.

[0074] In one embodiment, in the cooling mode, since the outlet water temperature and the inlet water temperature fluctuate greatly within a range of greater than or equal to negative five degrees Celsius and less than sixteen degrees Celsius, the difference between the outlet water temperature and the inlet water temperature of the water air conditioner during normal operation is generally greater than negative one degree Celsius. If the difference between the outlet water temperature and the inlet water temperature is less than or equal to negative one degree Celsius, it means that the first temperature sensor at the water inlet and the second temperature sensor at the water outlet of the water air conditioner are plugged in reverse. Therefore, the third preset temperature may be negative one degree Celsius, and the fifth preset temperature may be negative five degrees Celsius.

[0075] In one implementation, step S1023 may include the following steps S102306 to S102308:

[0076] Step S102306: If the operation mode of the water air conditioner is heating mode and the current water inlet temperature and outlet temperature are both greater than the seventh preset temperature and less than or equal to the eighth preset temperature, then control the water air conditioner to run for the first preset time, and then obtain the current water inlet temperature and outlet temperature again.

[0077] Step S102307: If the difference between the current water inlet temperature and the water outlet temperature is less than or equal to the third preset temperature, the fault information is determined to be the first fault information.

[0078] Step S102308: If the difference between the current water inlet temperature and the water outlet temperature is greater than the fourth preset temperature, the fault information is determined to be the second fault information.

[0079] In this embodiment, if the operation mode of the water air conditioner is the heating mode and the water inlet temperature and the water outlet temperature at the current moment are both greater than the seventh preset temperature and less than or equal to the eighth preset temperature, the water air conditioner is controlled to operate for the first preset time, and the water inlet temperature and the water outlet temperature at the current moment are obtained again. If the difference between the water inlet temperature and the water outlet temperature at the current moment is less than or equal to the third preset temperature, the fault information is determined to be the first fault information. If the difference between the water inlet temperature and the water outlet temperature at the current moment is greater than the fourth preset temperature, the fault information is determined to be the second fault information.

[0080] In one embodiment, the seventh preset temperature may be seven degrees Celsius.

[0081] In one implementation, the eighth preset temperature may be twenty degrees Celsius.

[0082] In one embodiment, in the heating mode, the difference between the water inlet temperature and the water outlet temperature of the water air conditioner during normal operation is greater than zero. If the difference between the water inlet temperature and the water outlet temperature is less than or equal to zero, it means that the first temperature sensor at the water inlet and the second temperature sensor at the water outlet of the water air conditioner are plugged in reverse. Therefore, the third preset temperature may be zero degrees Celsius.

[0083] In one embodiment, in the heating mode, if the first temperature sensor at the water inlet of the air conditioner and / or the second temperature sensor at the water outlet are not plugged in, the value measured by the first temperature sensor and / or the second temperature sensor will be larger than the actual value, thereby causing the difference between the outlet water temperature and the inlet water temperature to be larger. Therefore, the fourth preset temperature may be five degrees Celsius.

[0084] In one implementation, step S1023 may include the following steps S102309 to S102311:

[0085] Step S102309: If the operation mode of the water air conditioner is heating mode and the current water inlet temperature and outlet temperature are both greater than the ninth preset temperature and less than or equal to the seventh preset temperature, then control the water air conditioner to run for the first preset time, and then obtain the current water inlet temperature and outlet temperature again.

[0086] Step S102310: If the difference between the current water inlet temperature and the water outlet temperature is less than or equal to the sixth preset temperature, the fault information is determined to be the first fault information.

[0087] Step S102311: If the difference between the current water inlet temperature and the outlet water temperature is greater than or equal to the third preset temperature and less than or equal to the tenth preset temperature, control the compressor of the water air conditioner to run at the preset frequency for the second preset time, and then obtain the current water inlet temperature and the outlet water temperature again. If the difference between the current water inlet temperature and the outlet water temperature 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 current water inlet temperature and the outlet water temperature is greater than the fourth preset temperature, the fault information is determined to be the second fault information.

[0088] In this embodiment, if the operation mode of the water air conditioner is the heating mode and the water inlet temperature and the water outlet temperature at the current moment 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 operate for the first preset time, and the water inlet temperature and the water outlet temperature at the current moment are obtained again. If the difference between the water inlet temperature and the water outlet temperature at the current moment 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 water inlet temperature and the water outlet temperature at the current moment 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 operate at a preset frequency for the second preset time, and the water inlet temperature and the water outlet temperature at the current moment are obtained again. If the difference between the water inlet temperature and the water outlet temperature at the current moment is less than or equal to the tenth preset temperature, the fault information is determined to be the first fault information, and if the difference between the water inlet temperature and the water outlet temperature at the current moment is greater than the fourth preset temperature, the fault information is determined to be the second fault information.

[0089] In one embodiment, in the heating mode, since the outlet water temperature and the inlet water temperature have large fluctuations in the range of greater than or equal to minus 30 degrees Celsius and less than 7 degrees Celsius, the difference between the inlet water temperature and the outlet water temperature of the water air conditioner during normal operation is generally greater than minus 1 degree Celsius. If the difference between the inlet water temperature and the outlet water temperature is less than or equal to minus 1 degree Celsius, it means that the first temperature sensor at the water inlet and the second temperature sensor at the water outlet of the water air conditioner are plugged in reverse. Therefore, the third preset temperature may be minus 1 degree Celsius, and the ninth preset temperature may be minus 30 degrees Celsius.

[0090] 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 during normal operation 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, and then the inlet water temperature and the outlet water temperature at the current moment are obtained again. According to the working principle of the compressor frequency increase, the difference between the inlet water temperature and the outlet water temperature is generally within 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 means that the first temperature sensor and the second temperature sensor are plugged in reverse. If the difference between the inlet water temperature and the outlet water temperature is greater than five degrees Celsius, it means that the first temperature sensor and / or the second temperature sensor are plugged in falsely.

[0091] In one implementation, the second preset duration may be twenty minutes.

[0092] In one embodiment, the preset frequency may be eighty percent of the maximum frequency of the compressor.

[0093] Based on the above steps S101-S102, the present invention obtains the water inlet temperature through the first temperature sensor and obtains the water outlet temperature through the second temperature sensor. In response to the water air conditioner being turned on for the first time or being turned on at a preset interval, the fault information of the water air conditioner is obtained based on the water inlet temperature and the water outlet temperature, so as 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 invention can determine the fault information of the water air conditioner only through the water inlet temperature and the water outlet temperature, and then determine the fault of the first temperature sensor and / or the second temperature sensor according to the fault information. Accurate troubleshooting of sensors that affect the frequency operation of the water air conditioner compressor is achieved without increasing hardware costs.

[0094] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effects of the present invention, different steps do not have to be performed in such an order. They can be performed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present invention.
