[0002] As an emerging consumer appliance category, residential kitchen air conditioners primarily adopt a split-type structural design, including both wall-mounted and built-in models. Compared to commercial models, the core design requirements for residential kitchen air conditioners are a compact body to adapt to smaller kitchen spaces, oil and stain resistance, and intermittent operation modes.

[0003] Because household kitchen air conditioners need to operate in an environment with oil fumes, they face problems such as oil fume deposition, crude control strategies, and airflow interference. In order to solve these problems, existing traditional household kitchen air conditioners have been improved by installing a 25L water tank on the outside of the air conditioner, but the overall thickness is too large to meet the needs of household use. Alternatively, algorithms are used to control temperature fluctuations, but the problem of oil fume adhesion detection devices has not been solved. Therefore, there is an urgent need for a small household kitchen air conditioner with precise temperature control. Summary of the Invention

[0042] Figure 3 This is a flowchart illustrating a multimodal sensing water-cooled kitchen air conditioner control method provided in an embodiment of this application. Detailed Implementation

[0043] The present application will be further described in detail below with reference to the accompanying drawings.

[0044] This application provides a multimodal sensing water-cooled kitchen air conditioning control system, with reference to... Figure 1 The multimodal sensing water-cooled kitchen air conditioning control system mainly includes three major modules: the water-cooled kitchen air conditioning body, the water-cooled regulating device, and the regulating control system. The water-cooled kitchen air conditioning body is set as a cube shell. The water-cooled regulating device and the regulating control system are both installed inside the water-cooled kitchen air conditioning body. An air inlet is set on the side of the water-cooled kitchen air conditioning body that is close to the ground, and an air outlet is set on the side of the water-cooled kitchen air conditioning body.

[0045] Reference Figure 1 and Figure 2 The water-cooled regulating device includes a liquid-cooled radiator, a hot water exchange tank, a compressor, an evaporator, an electronic expansion valve, and an EC fan. The hot water exchange tank includes a tank body and refrigerant pipes installed inside the tank body. The liquid-cooled radiator, hot water exchange tank, compressor, evaporator, and electronic expansion valve are connected sequentially by pipes. Specifically, one end of the refrigerant pipe is connected to the compressor, and after the refrigerant enters the compressor, it is connected to the evaporator through a pipe and enters the evaporator. It is then connected to one end of the electronic expansion valve through a pipe, and the other end of the electronic expansion valve is connected to the liquid-cooled radiator through a pipe. The refrigerant flows through the electronic expansion valve into the liquid-cooled radiator. The liquid-cooled radiator is connected to the other end of the refrigerant pipe through a pipe, allowing the refrigerant to return to the refrigerant pipe. A water inlet pipe is connected to the end of the housing near the ground. A solenoid valve to control the water inlet and a flow valve to control the water flow are installed on the water inlet pipe. The flow valve is located on the side of the solenoid valve near the housing. A water outlet pipe is connected to the end of the housing away from the ground. External water is used to cool the refrigerant in the refrigerant pipe, and the heated water is discharged for circulation or reuse.

[0046] Reference Figure 1 and Figure 2The control system includes a controller mounted on the electronic control board, multiple temperature sensors installed at various locations on the water-cooled regulating device, and multiple control switches mounted on the compressor. The temperature sensors include a first temperature sensor on the water-cooled kitchen air conditioner body for detecting ambient temperature, a second sensor at the air inlet for detecting return air temperature, a third sensor at the air outlet for detecting exhaust temperature, a fourth sensor on the water outlet pipe for detecting outlet water temperature, and a fifth sensor on the refrigerant pipe for detecting refrigerant temperature. The specific locations of these sensors need to be added and adjusted according to actual needs and are not specifically limited here. The controller adjusts the operating status of the compressor, evaporator, and electronic expansion valve based on the collected temperature information and actual operating data. The control switches include a low-pressure switch and a high-pressure switch. When the controller detects that the high-pressure switch is open, it indicates that the pressure is too high and there is a danger, and the corresponding protection logic is invoked for protection. When the controller detects that the low-pressure switch is open, it indicates that the pressure is too high and pressure balancing is required.

[0047] Reference Figure 1 and Figure 2 The control system also includes an interactive control panel, which is an intelligent panel equipped with a touch screen and a voice recognition module. Users can adjust and view the temperature through the interactive control panel, and can also adjust the temperature by voice activation. It should be noted that multiple temperature sensors, multiple control switches, the interactive control panel, the compressor, solenoid valves, flow valves, electronic expansion valves, and EC fans are all electrically connected to the controller.

[0048] Figure 3 This is a flowchart illustrating a multimodal sensing water-cooled kitchen air conditioning control method provided in an embodiment of this application.

[0049] A multimodal sensing water-cooled kitchen air conditioner control method is applied to the multimodal sensing water-cooled kitchen air conditioner control system mentioned above.

[0050] like Figure 3 As shown, the main process of this method is described below (steps S101 to S105):

[0051] Step S101: In response to the user's startup operation, the water-cooling regulating device is initialized, and initialization data is generated.

[0052] In this embodiment, after the user initiates the startup operation, the water-cooled regulating device begins to operate and process data. After processing is completed, initialization data is generated. The entire process includes full-stroke calibration of the electronic expansion valve, full-stroke calibration of the flow valve, and operation of the EC fan according to the user-set speed. Then, the startup phase begins. For 0–3 minutes after the compressor starts, the compressor operates at a fixed 50Hz, and the MPC model data is preheated. Three minutes after the compressor starts, the next step is to calculate parameters based on the ambient temperature and the user-set temperature. During initialization, various data generated and detected by the water-cooled regulating device and the regulating control system are collected and processed to obtain initialization data. This initialization data includes key constraints: the pre-throttling temperature Tbefore_exp needs to be stable at 50±0.5℃; the total power Ptotal needs to be less than or equal to 1500W; for control inputs, the compressor target frequency Ftarget is controlled between 20–90Hz; the electronic expansion valve opening SEEV is controlled within 0–480 steps with 4-phase 8-step stepper drive; the flow valve opening V% is 0–100%; the EC fan speed range is 1–5; and for status monitoring parameters, the user-set target temperature Tset, ambient temperature Tamb, exhaust temperature Tdis, return gas temperature Tsuct, evaporator coil temperature Tcoil, pre-throttling temperature Tbefore_exp, and high / low pressure switch status are included. It should be noted that the above-mentioned data are values ​​that need to be observed or achieved during control processing; they are explained here together to reduce redundancy.

[0053] Step S102: Obtain the current ambient temperature and the user-set temperature.

[0054] In this embodiment, the user sets a target temperature when starting the operation. During operation, the environment needs to reach the target temperature. Therefore, the current ambient temperature needs to be collected at the same time as the user-set temperature, and the control process is performed according to the actual ambient temperature.

[0055] Step S103: Calculate the outer loop operating parameter data based on the current ambient temperature and the user-set temperature.

[0056] For step S103, the current ambient temperature is determined based on the current ambient temperature; the current temperature difference is calculated based on the current ambient temperature and the user-set temperature; the compressor frequency value is determined based on the temperature difference and the preset adjustment strategy; the previous temperature difference and dynamic compensation strategy are obtained; the frequency value is adjusted based on the previous temperature difference and the dynamic compensation strategy to generate outer loop operating parameter data.

[0057] In this embodiment, the current ambient temperature is extracted from all collected current ambient temperatures. The current ambient temperature is then subtracted from the user-set temperature to obtain the current temperature difference. A preset adjustment strategy and a dynamic compensation strategy are set. First, the compressor frequency value is determined according to the preset adjustment strategy. Then, the frequency value is adjusted according to the previous temperature difference and the dynamic compensation strategy to obtain the final outer loop operating parameter data. The preset adjustment strategy is as follows:

[0058] ;

[0059] in, Current temperature difference, For ambient temperature, The user sets a temperature. When the current temperature difference is greater than or equal to 3 degrees, the frequency value is 90. When the current temperature difference is less than 3 degrees but greater than or equal to -1 degree, the actual frequency value is calculated according to a linear formula. When the current temperature difference is less than -1 degree, the frequency value is 50. Then, a dynamic compensation strategy is used to adjust the frequency value. The dynamic compensation strategy is as follows:

[0060] d(ΔT) = ΔT current - ΔT previous;

[0061] dt=1 (execute once every 1 minute);

[0062] When d(ΔT) / dt>1℃ / min, Fbase increases by 10Hz (the temperature rises too quickly).

[0063] When d(ΔT) / dt < -3℃ / min, Fbase decreases by 10Hz (the temperature drops too quickly);

[0064] When 1℃ / min≥d(ΔT) / dt≥-3℃ / min, Fbase does not compensate.

[0065] Step S104: Based on the preset optimization strategy and initialization data, optimize the outer loop operation parameter data to generate optimized execution parameters.

[0066] For step S104, state variable relationships are constructed based on preset optimization strategies, initialization data, and outer loop operating parameter data; prediction data is generated based on preset prediction methods, state variable relationships, initialization data, and outer loop operating parameter data; constraints and collaborative strategies are obtained; and the prediction data is optimized and collaboratively processed based on constraints and collaborative strategies to generate optimized execution parameters.

[0067] In this embodiment, the preset optimization strategy is to use MPC for optimization. The core of the MPC model predictive control optimizer is to establish a state-space model of the system to accurately characterize the relationship between the system's "current state" and "adjustable variables," that is, to construct the state variable relationship, providing a foundation for subsequent state prediction and optimization decisions. The state variable relationship is as follows:

[0068] ;

[0069] Where x is a state variable, the key parameter that best reflects the operating state of the system is selected as the state variable; The current temperature difference directly reflects the gap between the air conditioning cooling effect and the target; Tbefore_exp-50 is the temperature deviation before throttling, that is, the difference between the refrigerant temperature at the outlet of the hot water tank and the target temperature of 50℃, used to monitor the stability of this core constraint parameter; Tdis is the compressor discharge temperature, reflecting the compressor operating load and safety; Tcoil is the evaporator coil temperature, reflecting the evaporator heat exchange efficiency and cooling capacity; u is the control input, selecting variables that the system can actively adjust as control inputs to change the system state; ΔF is the compressor frequency increment, that is, the difference between the actual compressor frequency Fcomp and the reference frequency value Fbase calculated by the outer loop (ΔF=Fcomp-Fbase), used to dynamically fine-tune the compressor power based on the reference frequency; ΔSEEV is the electronic expansion valve opening increment, that is, the difference between the current opening and the opening at the previous moment, used to adjust the refrigerant throttling and pressure reduction effect; ΔV% is the flow valve opening increment, that is, the difference between the current opening and the opening at the previous moment, used to adjust the cooling water flow rate of the hot water tank, affecting the refrigerant heat dissipation efficiency.

[0070] Numerical prediction is then performed using the prediction equation, which is the core of the MPC optimizer. The prediction equation is used to predict the changes in the system state at future moments based on the current state and control input, ensuring that the optimization decision can take into account long-term stability.

[0071] The dynamic equation for ambient temperature describes the variation of the ambient temperature deviation ΔT at future time steps. The core logic is that the temperature deviation at the next time step is determined by both the current deviation and the control input. The formula for the dynamic equation for ambient temperature is:

[0072] ΔT(k+1) = ΔT(k)-(Δt / τ)(KpΔF + Ks(ΔSEEV / Smax));

[0073] Wherein, ΔT(k+1) is the ambient temperature deviation for the next control cycle; ΔT(k) is the ambient temperature deviation at the current moment; Δt is the control cycle, which is generally set to 2 seconds; τ is the system thermal time constant, used to reflect the inertia of ambient temperature changes, i.e., the temperature response speed; Kp is the compressor gain, used to reflect the degree of influence of the compressor frequency increment ΔF on temperature changes. The larger the gain, the more significant the effect of frequency adjustment on cooling; ΔF is the compressor frequency increment, i.e., the difference between the actual compressor frequency Fcomp and the reference frequency value Fbase calculated by the outer loop (ΔF=Fcomp-Fbase), used to dynamically fine-tune the compressor power based on the reference frequency; Ks is the expansion valve gain, used to reflect the opening increment of the electronic expansion valve; ΔSEEV is the degree of influence on temperature changes; Smax=480 is the maximum opening of the expansion valve, and the consistency of the gain is ensured through normalization. That is, the rate of change of ambient temperature deviation is positively correlated with compressor power (frequency increment) and expansion valve throttling effect (opening increment). The higher the compressor frequency and the larger the expansion valve opening, the faster the ambient temperature drops and the more obvious the reduction in deviation.

[0074] To ensure that the refrigerant temperature at the outlet of the hot water exchanger tank remains stable at the target value of 50℃, which is near the core constraint, the following constraints are set:

[0075] The left side shows the absolute deviation of the temperature before throttling from 50℃; the right side shows the maximum allowable deviation range: the basic upper limit of the deviation is 0.5℃, but it will be dynamically adjusted according to the absolute value of the compressor frequency increment ΔF. This is an adjustment coefficient. When the compressor frequency changes significantly (|ΔF| increases), system load fluctuations may cause the temperature before throttling to deviate from the target temporarily. Therefore, the allowable deviation range is appropriately widened to avoid over-adjustment leading to system oscillation. If the frequency is stable (|ΔF| is close to 0), the deviation is strictly limited to within 0.5℃ to ensure precise temperature control.

[0076] The purpose of optimizing the objective function is to guide the adjustment direction of the control input, ultimately achieving multi-objective collaborative optimization of the system. The core of the objective function is to minimize the cost function J, with the following formula:

[0077] ;

[0078] The first part, i.e., the first addend after the equals sign and before the plus sign, represents the penalty for state deviation over the next 5 control cycles. ΔT(k+i) is the ambient temperature deviation in the i-th future cycle, and the squared term ensures that the larger the deviation, the heavier the penalty. (Tbefore_exp(k+i)-50)2 is the square of the pre-throttling temperature deviation in the i-th future cycle, which also reflects that the larger the deviation, the heavier the penalty. The weights α and β are the degree of importance attached to the accuracy of ambient temperature control and the stability of pre-throttling temperature, respectively. For example, the larger α is, the more priority is given to ensuring that the ambient temperature is close to the set value; the larger β is, the more priority is given to limiting pre-throttling temperature fluctuations. The second part, γPdev2, represents the power over-limit penalty. Pdev=max(0,Ptotal-1500) is the portion of the total power Ptotal exceeding 1500W. If it does not exceed the limit, Pdev=0. The weight γ is the strictness of the power limit. The larger γ is, the more priority is given to avoiding power over-limit. Ptotal=Pcomp+PEC_fan, where Pcomp is the current compressor power. When power penalty is required, it is based on the actual measured compressor frequency and power mapping relationship. In the 80~90Hz range, a 1Hz compressor frequency penalty is applied for every 30W. Below 80Hz, the compressor power is basically difficult to reach 1500W, so no penalty is applied.

[0079] According to the collaborative strategy, the MPC optimizer achieves three major objectives in synergy by minimizing J: rapidly bringing the ambient temperature close to the user-set value (minimizing ΔT); stabilizing the temperature before throttling at around 50℃ (minimizing deviation); and ensuring that the total system power does not exceed 1500W (minimizing the over-limit portion). By adjusting the weights α, β, and γ, the cooling effect, temperature stability, and energy consumption limits can be flexibly balanced according to actual needs.

[0080] The final optimized execution parameters include the compressor frequency decision result, where the target frequency = base frequency value + optimization increment: Ftarget = Fbase + ΔF; and the expansion valve-flow valve coordination result. Since both valves are powered by the onboard isolated switching power supply +12V, to reduce the power load, the valve action priority is implemented according to the following scheme: when Tbefore_exp ≥ 52℃, the flow valve takes priority, and the expansion valve takes priority after the flow valve has finished acting; when Tbefore_exp < 52℃, the expansion valve takes priority, and the flow valve takes priority after the expansion valve has finished acting.

[0081] Step S105: Control the water-cooling regulating device based on optimized execution parameters.

[0082] In this embodiment, after calculating the above-mentioned optimized execution parameters, the water cooling regulating device is controlled using the optimized execution parameters, thereby enabling the water cooling regulating device to achieve precise temperature control.

[0083] In this embodiment, the repetitive execution cycle is obtained, and the steps of repeatedly obtaining the current ambient temperature and the user-set temperature are repeated based on the repetitive execution cycle.

[0084] After the calculation is completed, a single result will not be used for consistent control. The data needs to be continuously adjusted according to the repeated execution cycle to achieve continuous and accurate control. When making adjustments, the process needs to start by obtaining the current ambient temperature and the user-set temperature and repeat and cycle the operation.

[0085] In this embodiment, a safety protection strategy is obtained, and the water-cooling regulating device is protected based on the safety protection strategy.

[0086] To ensure the safe operation of the water-cooled kitchen air conditioner, corresponding protection strategies are implemented to safeguard each component in the water-cooled regulating device. These safety protection strategies include overheat protection, abnormal water flow protection, water shortage detection, and power over-limit protection. Overheat protection is defined as SH = Tsuct - Tcoil, where Tsuct is the compressor suction temperature and Tcoil is the evaporator temperature. If SH < 3℃, the SEEV valve is forced to close for 5-10 steps per cycle. Abnormal water flow protection occurs when the flow valve opening is > 80% and Tbefore_exp > 52℃, causing the compressor frequency to decrease to 40Hz. Water shortage detection is performed every 2 seconds after the compressor has been running for 2 minutes. If the temperature before throttling is > 50℃ and > (exhaust temperature - 5℃), the unit shuts down for water shortage protection and reports an E1 fault. Power over-limit protection prioritizes frequency limiting for the compressor when Pcomp > 1400, and then reduces the compressor frequency when Pcomp > 1500.

[0087] In addition, when shutting down, it is also necessary to set the corresponding strategy to ensure the safety of the water cooling regulation device. The strategy is to shut down the compressor, maintain the flow valve opening at 50% for 30 seconds, increase the electronic expansion valve opening by 150 steps, and delay the compressor shutdown by 15 seconds.
