[0049] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0050] Example 1

[0051] The air conditioning control method proposed in the present invention can be applied to variable frequency air conditioning systems. Figure 1 An optional structural diagram of the variable frequency air conditioning system is shown in FIG. Figure 1 As shown, it includes a compressor 01, a four-way valve 9, an indoor fan system 08, an outdoor fan system 07, an indoor heat exchanger 05, an outdoor heat exchanger 02, a cooling electronic expansion valve 4, a heating electronic expansion valve 3, a one-way valve 10, a one-way valve 11, a high-pressure sensor 12, a low-pressure sensor 15, a temperature sensor package 13 for the middle tube of the outdoor heat exchanger, and a temperature sensor package 14 for the middle tube of the indoor heat exchanger.

[0052] Based on the above air conditioning unit, an air conditioning control method is provided in a preferred embodiment 1 of the present invention. The control method can be directly applied to various air conditioning units. Specifically, Figure 2 An optional flow chart of the method is shown as follows: Figure 2 As shown, the method includes the following steps S202-S208:

[0053] S202: Obtaining the temperature parameters of the tube temperature sensor in the outdoor heat exchanger;

[0054] S204: When the air conditioning unit is in high-pressure protection, determine whether there is a deviation in the pipe temperature sensor of the outdoor heat exchanger based on the temperature parameter;

[0055] S206: If there is a deviation in the temperature sensor package of the outdoor heat exchanger, the temperature parameter is corrected before the next cooling operation of the air conditioning unit, and the operation of the air conditioning unit is controlled according to the corrected temperature parameter;

[0056] S208: Otherwise, control the operation of the air-conditioning unit according to the temperature parameter.

[0057] Furthermore, after the temperature parameters are corrected, the method further includes:

[0058] The corrected temperature parameters are verified using the operating parameters of the air-conditioning unit, and the operation of the air-conditioning unit is controlled based on the verification results.

[0059] In the above embodiment, an air-conditioning control scheme is provided, which can detect possible deviations in the temperature detected by the temperature sensor package of the tube in the outdoor heat exchanger, take reasonable corrections to the deviations, and eliminate the troubles caused by inaccurate system parameters due to the deviations. The corrected temperature parameters are then verified by the operating parameters of the air-conditioning unit, and the operation of the air-conditioning unit is controlled according to the verification results. The operating parameters of the air-conditioning system are more accurate, so that the air-conditioning system is in an ideal operating state.

[0060] Determining whether the outdoor heat exchanger's central tube temperature sensor has deviated based on temperature parameters includes: obtaining a preset high-pressure protection temperature value; the preset high-pressure protection temperature value is the temperature value of the outdoor heat exchanger's central tube temperature sensor corresponding to when high-pressure protection is triggered; and determining whether the temperature parameter is greater than or equal to the preset high-pressure protection temperature value. If so, the temperature parameter is determined to be stable; otherwise, the outdoor heat exchanger's central tube temperature sensor is determined to have deviated. The outdoor central tube temperature sensor 13 detects the condensing pressure of the condenser 2, and the indoor central tube temperature sensor 14 detects the evaporating pressure of the evaporator 5. During cooling mode operation, the unit uses the central tube temperature sensors to detect system high pressure. When the set temperature is reached, the high-pressure device disconnects and high-pressure protection is triggered. The unit then immediately checks whether the temperature T1 of the outdoor central tube temperature sensor 13 has reached the preset high-pressure protection temperature value T0. If the temperature T1 of the outdoor central tube temperature sensor 13 is less than the preset high-pressure protection temperature value T0, the unit has experienced a mis-protection event, and the unit determines that the outdoor central tube temperature sensor 13 has deviated.

[0061] If the outdoor heat exchanger's tube temperature sensor is found to be deviated, two options are available for further temperature parameter correction. The first involves calculating the difference, Δt, between the preset high-pressure protection temperature and the temperature parameter. The corrected temperature parameter is equal to the sum of the temperature parameter and the difference, Δt. T1 is revised based on the difference between the preset high-pressure protection temperature and the measured value, resulting in the preset high-pressure value being T2 = T1 + Δt.

[0062] The second solution includes: adding a first preset temperature to the temperature parameter as a revised temperature parameter; determining whether the revised temperature parameter is equal to the preset high-pressure protection temperature value; if so, triggering the control of the operation of the air-conditioning unit according to the revised temperature parameter, otherwise continuing to add the first preset temperature to the temperature parameter. When the temperature T1 of the outdoor middle pipe temperature sensor 13 is less than the preset high-pressure protection temperature value T0, the unit is misprotected, and it is determined that there is a temperature deviation in the outdoor middle pipe temperature sensor 13 of the unit. According to the unit operating parameters, T1 is revised, and the preset high-pressure value becomes T2 = T1 + 2°C. Before the next cooling operation, the unit adds 2°C of temperature each time until the preset high-pressure value Tz = T1 + 2n is reached, and the system reaches the optimal state, and then the revision ends.

[0063] The corrected temperature parameter is verified using the operating parameters of the air conditioning unit, including: calculating the condensing temperature of the air conditioning unit; judging whether the corrected temperature parameter is equal to the condensing temperature; if the corrected temperature parameter is equal to the condensing temperature, the verification passes; otherwise, the verification fails.

[0064] Specifically, calculating the condensing temperature of the air-conditioning unit includes: obtaining the rated parameters of the air-conditioning unit and the suction pressure of the compressor; wherein the rated parameters of the air-conditioning unit include at least the power of the compressor, the adiabatic coefficient of the compressor under ideal conditions, and the mixing coefficient under the actual operating conditions of the air-conditioning unit; and calculating the compressor discharge pressure Pd using the following relationship: Where Pin is the compressor power, A is the mixing coefficient under the actual operating state of the air conditioning unit, K is the adiabatic coefficient of the compressor under ideal conditions, and Ps is the suction pressure of the compressor. The condensing temperature is calculated based on the exhaust pressure.

[0065] If the verification passes, the air conditioning unit's operation is controlled based on the revised temperature parameters. If the verification fails, the revised temperature parameters are further revised using the condensing temperature, and the air conditioning unit's operation is then controlled based on the revised results. Specifically, revising the revised temperature parameters using the condensing temperature includes: determining a second preset temperature based on the condensing temperature; and superimposing the revised temperature parameters on the second preset temperature. The second preset temperature is the difference Δt' between the condensing temperature and the preset high-voltage protection temperature.

[0066] When the calculated condensing temperature value T3 equals the unit's preset high-pressure value Tz, the unit is operating. If the calculated condensing temperature value T3 is not equal to the unit's preset high-pressure value Tz, the preset high-pressure value Tz needs to be revised based on the calculated value T3, i.e., Tz' = Tz + △t'. By using the revised and verified preset high-pressure protection temperature value as the limiting condition for the next cooling operation, the unit can better achieve optimal operation.

[0067] The calculated condensing temperature is compared with the revised high-pressure protection temperature. For example: the condensing temperature is 58°C and the high-pressure protection temperature is 60°C, but the unit has high-pressure protection, indicating a 2°C deviation. The revised measured temperature value is 58+2°C, and the high-pressure protection temperature is 60°C, which is called the revised preset high-pressure protection temperature value. 2°C is the second preset temperature.

[0068] Another air conditioning control method is provided in the preferred embodiment 1 of the present invention. Specifically, Figure 3 An optional flow chart of the method is shown as follows: Figure 3 As shown, the method includes the following steps S301-S309:

[0069] S301: System cooling mode high pressure protection;

[0070] S302: Is the temperature T1 of the outdoor heat exchanger's middle tube temperature sensor greater than the set protection value T0? If so, proceed to S303; otherwise, proceed to S304.

[0071] S303: The system reports a high voltage protection fault;

[0072] S304: There is a deviation of Δt=T0-T1, and the next high-voltage protection measurement value is T2=T1+Δt; T1 is revised according to the difference between the preset high-voltage protection temperature value and the detection value, and the preset high-voltage value becomes T2=T1+Δt;

[0073] S305: Check whether the temperature T3 corresponding to the condensing pressure is equal to the revised T2 by using the suction pressure and compressor power; if so, proceed to S307; otherwise, proceed to S306;

[0074] S306: Revise T4=T2+Δt';

[0075] S307: System adjusts pressure;

[0076] S308: Determine whether the system is in secondary high-voltage protection; if so, proceed to S301, otherwise, proceed to S309;

[0077] S309: Output T4.

[0078] When the system enters high-pressure protection, the system checks whether the temperature T1 detected by the middle tube temperature sensor is greater than the preset high-pressure protection temperature T0. If so, the system is normal. If not, there is a deviation in the detection value T1. For example, if the actual detection temperature is 58°C and the high-pressure protection temperature is 60°C, then the detection value of 58°C is equivalent to a temperature of 60°C, and there is a deviation in the detection value △t = 60-58 = 2°C. In this case, the detection value T2 will automatically increase by 2°C next time, and the preset high-pressure protection temperature of 60°C will remain unchanged.

[0079] Because there is a deviation in the detection value, the deviation is verified next. The actual condensation temperature T3 is inferred through parameters such as suction pressure and compressor power. It is determined whether there is a deviation between the actual measured value T2 displayed by the system and the inferred measured value T3. Normally, they should be consistent. If there is still a deviation, △t'=T3-T2, and the system detection value T2 is revised. The actual system should display the value T4=T2+△t'. For example: the detection value T2 is 58℃, and the converted condensation temperature T3 is 59.5℃, with a deviation of 1.5℃, so T2 is revised.

[0080] To sum up, the system's preset high pressure remains unchanged, and the revisions are always based on the system's actual measured values.

[0081] The present invention detects deviations in the outdoor heat exchanger's mid-tube temperature sensor and promptly corrects them, accurately outputting system parameters. Two methods are available for correcting existing deviations, enabling optimal selection for different units. After correction, parameters such as compressor power and the relationship between system high and low pressures can be used for calibration, ensuring optimal air conditioning unit operation.
