Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an anti-condensation control method, device, air conditioning equipment and storage medium. Background Technology

[0002] With the rapid development of science and technology, air conditioning equipment has become increasingly sophisticated and widely used. To ensure a better user experience, air conditioning systems in heating or cooling modes have evolved from simply blowing cold or hot air directly to dividing the indoor heat exchanger into at least two sections. This allows the air conditioner to simultaneously output air at different temperatures, reducing the possibility of user discomfort. Currently, this division of the indoor heat exchanger into at least two sections is primarily achieved through normally open solenoid valves installed on the corresponding sections. These valves control the flow of refrigerant, allowing for the output of air at different temperatures and improving the user experience.

[0003] However, during the process of implementing multi-temperature cooling mode in air conditioning equipment, cold air of different temperatures will mix, resulting in condensation problems. Currently, there is no effective method to solve the condensation problem in multi-temperature cooling mode.

[0004] Application content

[0005] To address the aforementioned technical problems, this application aims to provide an anti-condensation control method, device, air conditioning equipment, and storage medium. This solves the problem of condensation easily occurring when air conditioning equipment is in a multi-temperature cooling mode. An anti-condensation control method is proposed to reduce the probability of condensation in air conditioning equipment and ensure the quality of the air conditioning equipment.

[0006] The technical solution of this application is implemented as follows:

[0007] In a first aspect, a method for preventing condensation control, the method comprising:

[0008] When the air conditioning equipment is operating in a multi-temperature cooling mode, the temperature parameters of the evaporator corresponding to m target switch valves that are in a closed state are obtained to obtain m first reference temperature parameters; wherein, the target switch valve is used to control the flow rate of refrigerant flowing through the evaporator of the indoor unit of the air conditioning equipment connected to the target switch valve, and m is an integer greater than or equal to 1;

[0009] The temperature parameters of n evaporators in the air conditioning equipment, excluding the m evaporators corresponding to the target switching valves, are obtained to obtain n second reference temperature parameters; where n is an integer greater than or equal to 1.

[0010] Obtain the environmental parameters of the current environment in which the air conditioning equipment is located;

[0011] Based on m first reference temperature parameters, n second reference temperature parameters, and the environmental parameters, the reference operating parameters of the air conditioning equipment are determined;

[0012] Based on the current operating parameters of the air conditioning equipment and the reference operating parameters, the target operating parameters of the air conditioning equipment are determined;

[0013] Switch the operating parameters of the air conditioning equipment to the target operating parameters.

[0014] Secondly, an anti-condensation control device, the device comprising: an acquisition unit, a determination unit, and a switching unit; wherein:

[0015] The acquisition unit is used to acquire the temperature parameters of the evaporators corresponding to m target switch valves that are in a closed state when the air conditioning equipment is operating in a multi-temperature cooling mode, and to obtain m first reference temperature parameters; wherein, the target switch valve is used to control the flow rate of refrigerant flowing through the evaporator in the indoor unit of the air conditioning equipment connected to the target switch valve, and m is an integer greater than or equal to 1;

[0016] The acquisition unit is further configured to acquire the temperature parameters of n evaporators in the air conditioning equipment, excluding the m evaporators corresponding to the target switching valves, to obtain n second reference temperature parameters; where n is an integer greater than or equal to 1.

[0017] The acquisition unit is also used to acquire environmental parameters of the environment in which the air conditioning equipment is currently located;

[0018] The determining unit is used to determine the reference operating parameters of the air conditioning equipment based on m first reference temperature parameters, n second reference temperature parameters and the environmental parameters;

[0019] The determining unit is further configured to determine the target operating parameters of the air conditioning equipment based on the current operating parameters of the air conditioning equipment and the reference operating parameters;

[0020] The switching unit is used to switch the operating parameters of the air conditioning equipment to the target operating parameters.

[0021] Thirdly, an air conditioning device, the device comprising: an indoor unit, an outdoor unit, and an anti-condensation control device as described above.

[0022] Fourthly, a storage medium storing an anti-condensation control program, which, when executed by a processor, implements the steps of the anti-condensation control method as described in any of the preceding claims.

[0023] In this embodiment, when the air conditioning equipment is operating in a multi-temperature cooling mode, the temperature parameters of the evaporators corresponding to m target valves that are in a closed state are obtained to obtain m first reference temperature parameters. The temperature parameters of n evaporators in the air conditioning equipment (excluding those corresponding to the m target valves) are obtained to obtain n second reference temperature parameters. The environmental parameters of the current environment in which the air conditioning equipment is located are also obtained. Finally, based on the m first reference temperature parameters, n second reference temperature parameters, and environmental parameters, the reference operating parameters of the air conditioning equipment are determined. Then, based on the current operating parameters and reference operating parameters, the target operating parameters of the air conditioning equipment are determined, and the operating parameters of the air conditioning equipment are switched to the target operating parameters. Thus, when the air conditioning equipment is operating in a multi-temperature cooling mode, the operating parameters of the air conditioning equipment are determined by the temperatures of the evaporators corresponding to the m target valves, the temperatures of the n other evaporators, and the environmental parameters of the current environment. By adjusting the operating parameters of the air conditioning equipment, the occurrence of condensation can be reduced, solving the problem of condensation that easily occurs when the air conditioning equipment is in a multi-temperature cooling mode. This proposes an anti-condensation control method, reducing the probability of condensation in the air conditioning equipment and ensuring the quality of the air conditioning equipment.

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0034] The embodiments of this application provide a method for preventing condensation control, referring to... Figure 1 As shown, the method is applied to air conditioning equipment, and the method includes the following steps:

[0035] Step 101: When the air conditioning equipment is operating in the multi-temperature cooling mode, obtain the temperature parameters of the evaporator corresponding to the m target switch valves that are in the closed state, and obtain the m first reference temperature parameters.

[0036] The target switching valve is used to control the flow rate of refrigerant flowing through the evaporator of the indoor unit of the air conditioning equipment connected to the target switching valve, where m is an integer greater than or equal to 1.

[0037] In this embodiment of the application, in order to ensure the user experience, the air conditioning equipment can output cold air of different temperatures at the same time when cooling. This can be achieved by replacing one evaporator with at least two evaporators in the indoor unit of the air conditioning equipment, and setting a switch valve on the evaporator to control the refrigerant passing through each evaporator. Thus, when the air conditioning equipment is in cooling mode, air of different temperatures can be output through each evaporator.

[0038] In the multi-temperature cooling mode, when outputting air at multiple temperatures, the lowest temperature output air is usually positioned at the top of the space. This helps to suppress the rise of hot air, thus ensuring that the user's head is cool while their body is warm, improving the user experience.

[0039] When the air conditioning equipment is currently operating in a multi-temperature cooling mode, it can control m target switching valves to be closed according to actual needs. This allows the air conditioning equipment to output airflow at various cold temperatures. The target switching valve is a switching valve that controls the refrigerant flow rate; specifically, it can be a solenoid valve, such as a normally open or normally closed solenoid valve. When the target switching valve is a normally open or normally closed solenoid valve, its on / off state can be controlled by whether or not a power supply is provided to it. m can be the total number of switching valves in the air conditioning equipment used to control the refrigerant flow rate through the evaporator. It should be noted that in this case, at least one evaporator is not equipped with a switching valve for controlling the refrigerant flow rate. m can also be a partial number of switching valves in the air conditioning equipment used to control the refrigerant flow rate through the evaporator. In this case, all evaporators in the air conditioning equipment can be connected to switching valves for controlling the refrigerant flow rate, or only some evaporators can be connected to switching valves for controlling the refrigerant flow rate.

[0040] Temperature parameters of each target switching valve are collected by temperature sensors installed on the evaporators corresponding to the m target switching valves, resulting in m first reference temperature parameters.

[0041] Step 102: Obtain the temperature parameters of n evaporators in the air conditioning equipment, excluding the evaporators corresponding to the m target switching valves, to obtain n second reference temperature parameters.

[0042] Where n is an integer greater than or equal to 1.

[0043] In this embodiment, the air conditioning equipment includes a total of m+n evaporators. The n evaporators, excluding the m target switching valves, can all be equipped with switching valves, or some can be equipped with switching valves, or none of them can be equipped with switching valves. Temperature sensors are also installed on the n evaporators excluding the m target switching valves; therefore, temperature parameters of the n evaporators excluding the m target switching valves can be collected to obtain n second reference temperature parameters.

[0044] Step 103: Obtain the environmental parameters of the current environment in which the air conditioning equipment is located.

[0045] In this embodiment of the application, the current environment of the air conditioning equipment refers to the space where the air conditioning equipment is currently located. The environmental parameters include at least the environmental humidity parameter, and may further include the environmental temperature parameter.

[0046] Step 104: Based on m first reference temperature parameters, n second reference temperature parameters, and environmental parameters, determine the reference operating parameters of the air conditioning equipment.

[0047] In this embodiment of the application, m first reference temperature parameters and n second reference temperature parameters are compared and analyzed to obtain analysis results. Based on the analysis results and environmental parameters, the reference operating parameters of the air conditioning equipment are determined.

[0048] Step 105: Based on the current operating parameters and reference operating parameters of the air conditioning equipment, determine the target operating parameters of the air conditioning equipment.

[0049] In this embodiment of the application, the reference operating parameters are compared and analyzed with the current operating parameters of the air conditioning equipment to determine the target operating parameters that need to be adjusted.

[0050] Step 106: Switch the operating parameters of the air conditioning equipment to the target operating parameters.

[0051] In this embodiment, the operating parameters of the air conditioning equipment are adjusted to the target operating parameters. This can effectively prevent condensation problems in the air conditioning equipment, reduce the probability of condensation, and ensure the quality of the air conditioning equipment.

[0052] In this embodiment, when the air conditioning equipment is operating in a multi-temperature cooling mode, the temperature parameters of the evaporators corresponding to m target valves that are in a closed state are obtained to obtain m first reference temperature parameters. The temperature parameters of n evaporators in the air conditioning equipment (excluding those corresponding to the m target valves) are obtained to obtain n second reference temperature parameters. The environmental parameters of the current environment in which the air conditioning equipment is located are also obtained. Finally, based on the m first reference temperature parameters, n second reference temperature parameters, and environmental parameters, the reference operating parameters of the air conditioning equipment are determined. Then, based on the current operating parameters and reference operating parameters, the target operating parameters of the air conditioning equipment are determined, and the operating parameters of the air conditioning equipment are switched to the target operating parameters. Thus, when the air conditioning equipment is operating in a multi-temperature cooling mode, the operating parameters of the air conditioning equipment are determined by the temperatures of the evaporators corresponding to the m target valves, the temperatures of the n other evaporators, and the environmental parameters of the current environment. By adjusting the operating parameters of the air conditioning equipment, the occurrence of condensation can be reduced, solving the problem of condensation that easily occurs when the air conditioning equipment is in a multi-temperature cooling mode. This proposes an anti-condensation control method, reducing the probability of condensation in the air conditioning equipment and ensuring the quality of the air conditioning equipment.

[0053] Based on the foregoing embodiments, embodiments of this application provide an anti-condensation control method, which is applied to air conditioning equipment, with reference to... Figure 2 As shown, the method includes the following steps:

[0054] Step 201: When the air conditioning equipment is operating in the multi-temperature cooling mode, obtain the temperature parameters of the evaporator corresponding to the m target switch valves that are in the closed state, and obtain the m first reference temperature parameters.

[0055] The target switching valve is used to control the flow rate of refrigerant flowing through the evaporator of the indoor unit of the air conditioning equipment connected to the target switching valve, where m is an integer greater than or equal to 1.

[0056] In this embodiment, the air conditioning equipment operates in a multi-temperature cooling mode. Temperature parameters are collected by temperature sensors on each evaporator to obtain the first reference temperature parameters of the evaporators corresponding to the m target valves that are in a closed state. The m target valves in a closed state include valves that are completely closed and valves that are not completely closed; that is, the m target valves in a closed state include valves with an opening degree of 0 and / or valves with an opening degree greater than 0 but less than the maximum opening degree.

[0057] For example, such as Figure 3 The diagram shown is a schematic of the circuit connection structure of an air conditioning device in dual-temperature cooling mode according to an embodiment of this application. Evaporator 1 is connected to a solenoid valve, while evaporator 2 is not connected to a solenoid valve. Temperature sensor 1 is installed on evaporator 1, and temperature sensor 2 is installed on evaporator 2. Figure 3 The direction of the middle arrow indicates the refrigerant transmission direction in the dual-temperature cooling operation mode. When the solenoid valve connected to evaporator 1 is a normally open solenoid valve, it should currently be energized to keep it closed. The temperature parameters of evaporator 1 are collected by temperature sensor 1 to obtain the first reference temperature parameter. Correspondingly, Figure 3 A schematic diagram illustrating the air output of the corresponding air conditioning unit when it is in dual-temperature cooling mode can be found here. Figure 4 As shown, the air output from the upper layer of the air conditioning unit is cold air, while the air from the lower layer is not supplied with refrigerant to the evaporator 1 connected to the normally open solenoid valve due to the closure of the normally open solenoid valve. Therefore, the air output from the evaporator 1 is natural cool air.

[0058] Step 202: Obtain the temperature parameters of n evaporators in the air conditioning equipment, excluding the evaporators corresponding to the m target switching valves, to obtain n second reference temperature parameters.

[0059] Where n is an integer greater than or equal to 1.

[0060] In this embodiment of the application, the temperature parameters of the evaporator 2 are collected by the temperature sensor 2 to obtain the second reference temperature parameter.

[0061] Step 203: Obtain the environmental parameters of the current environment in which the air conditioning equipment is located.

[0062] In this embodiment of the application, the environmental parameters of the current air conditioning equipment can be collected by an environmental parameter acquisition device installed on the air conditioning equipment, or they can be collected by an environmental parameter acquisition device that is not integrated with the air conditioning equipment but has a communication connection with it, and then sent to the air conditioning equipment.

[0063] For example, environmental parameters are collected by an environmental parameter acquisition device installed on the air conditioning equipment. The environmental parameters are, for example, the environmental humidity parameters.

[0064] Step 204: Determine the first target temperature parameter based on m first reference temperature parameters.

[0065] In this embodiment, m first reference temperature parameters are compared and analyzed to determine a temperature parameter, thus obtaining a first target temperature parameter. When m is 1, the first target temperature parameter can be determined to be the same as the first reference temperature parameter. When m is greater than or equal to 2, the largest temperature parameter can be determined from the m first reference temperature parameters as the first target temperature parameter, or the average value of the m first reference temperature parameters can be calculated to obtain the first target temperature parameter. Alternatively, the average value of temperature parameters greater than a first preset threshold can be determined from the m first reference temperature parameters as the first target temperature parameter, or the average value of the evaporator temperature corresponding to the target valve with an opening degree of 0 can be determined from the m first reference temperature parameters as the first target temperature parameter.

[0066] For example, when only the first reference temperature parameter of evaporator 1 is available, the first target temperature parameter can be directly determined as the first reference temperature parameter of evaporator 1.

[0067] Step 205: Determine the second target temperature parameter based on n second reference temperature parameters.

[0068] In this embodiment, n second reference temperature parameters are compared and analyzed to determine one temperature parameter, thus obtaining a second target temperature parameter. When n is 1, the second target temperature parameter is determined as the second reference temperature parameter; when n is greater than or equal to 2, the smallest temperature parameter can be determined from the n second parameters as the second target temperature parameter, or the average value of the n second reference temperature parameters can be calculated to obtain the second target temperature parameter, or the average value of temperature parameters less than or equal to a second preset threshold can be determined from the n second reference temperature parameters as the second target temperature parameter.

[0069] For example, if only the second reference temperature parameter of evaporator 2 is available, the second target temperature parameter can be directly determined as the second reference temperature parameter of evaporator 2.

[0070] Step 206: Determine reference operating parameters based on the first target temperature parameter, the second target temperature parameter, and environmental parameters.

[0071] In this embodiment, the first target temperature parameter and the second target temperature parameter are analyzed to obtain the analysis results. Based on the analysis results and environmental parameters, reference operating parameters are determined. The reference operating parameters may be the operating frequency of the compressor in the air conditioning equipment, or the opening degree of the throttling device in the air conditioning equipment.

[0072] For example, reference operating parameters are determined based on a first reference temperature parameter of evaporator 1, a second reference temperature parameter of evaporator 2, and environmental parameters such as ambient humidity.

[0073] Step 207: Determine the target operating parameters of the air conditioning equipment based on the current operating parameters and reference operating parameters of the air conditioning equipment.

[0074] In this embodiment of the application, the current operating parameters of the air conditioning equipment are determined, and the target operating parameters of the air conditioning equipment are determined based on the current operating parameters and reference operating parameters.

[0075] Step 208: Switch the operating parameters of the air conditioning equipment to the target operating parameters.

[0076] In this embodiment of the application, after switching the operating parameters of the air conditioning equipment to the target operating parameters, the temperature difference between the airflows output by the air conditioning equipment can be adjusted, reducing the possibility of condensation and preventing condensation, thus ensuring the performance of the air conditioning equipment.

[0077] Based on the foregoing embodiments, in other embodiments of this application, step 204 can be implemented by step 204a or steps 204b to 204c:

[0078] Step 204a: From the m first reference temperature parameters, determine the temperature parameter with the largest parameter value to obtain the first target temperature parameter.

[0079] Step 204b: Select at least one third reference temperature parameter from the m first reference temperature parameters that is greater than the first preset temperature parameter.

[0080] In the embodiments of this application, the first preset temperature parameter can be an empirical value obtained from a large number of experiments, and can be continuously corrected according to the actual situation.

[0081] Step 204c: Determine the first target temperature parameter based on at least one third reference temperature parameter.

[0082] In the embodiments of this application, at least one third reference temperature parameter can be averaged to obtain the first target temperature parameter.

[0083] Based on the foregoing embodiments, in other embodiments of this application, step 205 can be implemented by step 205a or steps 205b to 205c:

[0084] Step 205a: From the n second reference temperature parameters, determine the temperature parameter with the smallest value to obtain the second target temperature parameter.

[0085] Step 205b: Select at least one fourth reference temperature parameter from the n second reference temperature parameters that is less than the second preset temperature parameter.

[0086] In this embodiment, the second preset temperature parameter can be an empirical value obtained from a large number of experiments, and can be continuously corrected according to the actual situation.

[0087] Step 205c: Determine the second target temperature parameter based on at least one fourth reference temperature parameter.

[0088] In this embodiment of the application, the average value of at least one fourth reference temperature parameter is calculated to obtain the second target temperature parameter.

[0089] Based on the foregoing embodiments, in other embodiments of this application, step 206 can be implemented by steps 206a to 206b:

[0090] Step 206a: Determine the target difference between the first target temperature parameter and the second target temperature parameter.

[0091] In this embodiment of the application, the temperature difference between the highest temperature airflow and the lowest temperature airflow output by the air conditioning equipment in the multi-temperature cooling mode is determined by the formula target difference = first target temperature parameter - second target temperature parameter, or the formula target difference = |second target temperature parameter - first target temperature parameter|, and the target difference is obtained.

[0092] Step 206b: Determine the reference operating parameters based on the target difference and environmental parameters.

[0093] In this embodiment of the application, the target difference and environmental parameters are analyzed to determine the reference operating parameters.

[0094] Based on the foregoing embodiments, in other embodiments of this application, when the object of adjustment for the air conditioning equipment is the compressor of the air conditioning equipment, step 206b can be implemented by steps a11 to a13:

[0095] Step a11: Determine the first preset relationship between temperature change and ambient humidity parameters and compressor operating frequency.

[0096] In the embodiments of this application, the first preset relationship can be an empirical relationship obtained from a large number of experiments, in the multi-temperature cooling mode, when the compressor operates at different operating frequencies to correspond to different ambient humidity parameters for different temperature changes between the output airflow of different air conditioning devices, condensation will not occur. Specifically, it can be represented in the form of a list or in the form of an empirical formula.

[0097] Step a12: Determine the target operating frequency that matches the target difference and the current humidity parameter in the environmental parameters from the first preset relationship.

[0098] In this embodiment of the application, the target operating frequency of the compressor is determined from the first preset relationship based on the determined target difference and the current humidity parameter in the environmental parameters.

[0099] For example, if the first preset relationship is an empirical formula, the target difference and the current humidity parameter can be substituted into the first preset relationship, and the target operating frequency can be obtained by calculation.

[0100] Step a13: Determine the reference operating parameters as the target operating frequency.

[0101] In this embodiment of the application, the reference operating parameter of the air conditioning equipment is determined to be the target operating frequency of the compressor.

[0102] Correspondingly, in other embodiments of this application, step 207 can be implemented by step 207a or step 207b:

[0103] Step 207a: If the current operating frequency of the air conditioning equipment is greater than the target operating frequency, determine the target operating parameter as the target operating frequency.

[0104] The current operating parameters of the air conditioning equipment include the current operating frequency of the air conditioning compressor.

[0105] In this embodiment of the application, when the current operating frequency of the compressor of the air conditioning equipment is greater than the target operating frequency, it is necessary to reduce the operating frequency of the compressor to the target operating frequency.

[0106] Step 207b: If the current operating frequency of the air conditioning equipment is less than or equal to the target operating frequency, determine the target operating parameter as the current operating frequency.

[0107] In this embodiment of the application, when the current operating frequency of the air conditioning equipment is less than or equal to the target operating frequency, the current operating frequency of the air conditioning equipment compressor is maintained without adjustment.

[0108] Based on the foregoing embodiments, in other embodiments of this application, when the controlled object of the air conditioning equipment is a throttling device, step 206b can be implemented by steps b11 to b13:

[0109] Step b11: Determine the second preset relationship between temperature change and ambient humidity parameters and the opening degree of the throttling device.

[0110] In this embodiment, the second preset relationship can be an empirical determination of the opening degree of the throttling device to prevent condensation in the air conditioning equipment by conducting extensive experimental analysis on the air conditioning equipment and determining the opening degree of the throttling device to prevent condensation in the air conditioning equipment when the airflow output by the air conditioning equipment corresponds to different environmental humidity parameters at different temperature changes. Specifically, it can be represented in a list form or by an empirical formula.

[0111] Step b12: Determine the target opening degree that matches the target difference and the current humidity parameter in the environmental parameters from the second preset relationship.

[0112] In this embodiment of the application, the target opening degree is determined from the second preset relationship based on the target difference and the current humidity parameter included in the environmental parameters.

[0113] For example, if the second preset relationship is an empirical relationship in the form of a list with the difference on the horizontal axis and the humidity parameter on the vertical axis, the target opening value is obtained by finding the opening value corresponding to the target difference on the horizontal axis and the current humidity parameter on the vertical axis from the second preset relationship.

[0114] Step b13: Determine the reference operating parameters as the target opening.

[0115] In this embodiment of the application, the target opening degree of the throttling device is determined based on reference operating parameters.

[0116] Correspondingly, in other embodiments of this application, step 207 can be implemented by step 207c or step 207d:

[0117] Step 207c: If the current opening degree of the throttling device of the air conditioning equipment is less than the target opening degree, determine the target operating parameter as the target opening degree.

[0118] In this embodiment of the application, when the current opening degree of the throttling device of the air conditioning equipment is less than the target opening degree, the opening degree of the throttling device of the air conditioning equipment is amplified.

[0119] Step 207d: If the current opening is greater than or equal to the target opening, determine the target operating parameter as the current opening.

[0120] In this embodiment of the application, when the current opening degree of the throttling device is greater than or equal to the target opening degree, the opening degree of the throttling device is kept at the current opening degree and no adjustment is made.

[0121] Based on the foregoing embodiments, in other embodiments of this application, reference is made to... Figure 5 As shown, after the air conditioning equipment performs step 208, it is also used to perform step 209:

[0122] Step 209: After a preset time interval, repeat the steps to obtain the temperature parameters of the evaporators corresponding to the m target switch valves that are in the closed state, and obtain m first reference temperature parameters until an exit command is received to indicate exiting the multi-temperature working mode of refrigeration.

[0123] In this embodiment, the preset duration is the empirical duration, obtained from a large number of experiments, during which the evaporator temperature changes significantly after switching the operating parameters of the air conditioning equipment when the air conditioning equipment is in a multi-temperature cooling mode.

[0124] After adjusting the operating parameters of the air conditioning equipment to the target operating parameters for a preset time, the process is repeated from step 201 until an exit command to exit the multi-temperature cooling mode is received. That is, after adjusting the operating parameters of the air conditioning equipment to the target operating parameters for a preset time, the temperature of the m+n evaporators of the air conditioning equipment is detected again. Based on the temperature difference of the evaporators, the operating parameters of the air conditioning equipment are continuously adjusted to ensure that the air conditioning equipment will not experience condensation during the entire use process.

[0125] It should be noted that if condensation is prevented by simultaneously controlling the compressor operating frequency and the opening degree of the throttling device of the air conditioning equipment, step 206c can be achieved by steps a11 to a13 and steps b11 to b13.

[0126] Based on the foregoing embodiments, this application provides an application embodiment of an anti-condensation control method that adjusts the operating frequency of the compressor in an air conditioning unit, wherein the air conditioning unit is in a state such that... Figure 3 The dual-temperature cooling operating mode shown is for reference. Figure 6 As shown, it includes the following steps:

[0127] Step 301: After the air conditioning equipment switches to the dual-temperature cooling mode for a certain period of time, collect the temperature parameter T1 of evaporator 1, the temperature parameter T2 of evaporator 2, and the current ambient humidity parameter S of the space where the air conditioning equipment is located.

[0128] The duration can be, for example, 5 minutes.

[0129] Step 302: Calculate T = T2 - T1.

[0130] Step 303: Use a lookup table to find the target operating frequencies corresponding to T and S from the first preset relationship.

[0131] The first preset relationship can be shown in Table 1.

[0132] Table 1 First Preset Relationship

[0133]

[0134] In some application scenarios, the first preset relationship can also be expressed as Fmn = f(T, S), where T and Fmn are negatively correlated, and S is also negatively correlated with Fmn. It should be noted that regardless of whether the first preset relationship is in tabular or computational form, it is related to the system configuration of the air conditioning equipment, such as the size of the evaporator and condenser, the compressor displacement, and the throttling device control method. Different air conditioning equipment will have different corresponding first preset relationships, which need to be determined through experimental testing and fitting based on the manufacturer's system configuration.

[0135] Step 304: Determine whether the current operating frequency of the air conditioning compressor is greater than the target operating frequency. If yes, proceed to step 305; otherwise, proceed to step 301.

[0136] Step 305: Control the operating frequency of the air conditioning equipment compressor to the target operating frequency.

[0137] Based on the foregoing embodiments, this application provides an application embodiment of an anti-condensation control method that adjusts the opening degree of the throttling device of an air conditioning unit, wherein the air conditioning unit is in the following state: Figure 3 The dual-temperature cooling operating mode shown is for reference. Figure 7 As shown, it includes the following steps:

[0138] Step 401: After the air conditioning equipment switches to the dual-temperature cooling mode for a certain period of time, collect the temperature parameter T1 of evaporator 1, the temperature parameter T2 of evaporator 2, and the current ambient humidity parameter S of the space where the air conditioning equipment is located.

[0139] The duration can be, for example, 5 minutes.

[0140] Step 402: Calculate T = T2 - T1.

[0141] Step 403: Use a lookup table to retrieve the target opening degree corresponding to T and S from the second preset relationship.

[0142] Table 2 Second Preset Relationship

[0143]

[0144] The second preset relationship can be shown in Table 2.

[0145] In some application scenarios, the first preset relationship can also be expressed as Kmn = f(T, S), where T and Kmn are positively correlated, and S is also positively correlated with Kmn. It should be noted that regardless of whether the second preset relationship is in tabular or computational form, it is related to the system configuration of the air conditioning equipment, such as the size of the evaporator and condenser, the compressor displacement, and the throttling device control method. Different air conditioning equipment will have different corresponding second preset relationships, which need to be determined through experimental testing and fitting based on the manufacturer's system configuration.

[0146] Step 404: Determine whether the current opening degree of the air conditioning equipment throttling device is less than the target opening degree. If yes, proceed to step 405; otherwise, proceed to step 401.

[0147] Step 405: Control the opening degree of the throttling device of the air conditioning equipment to the target opening degree.

[0148] It should be noted that the embodiments corresponding to steps 301-305 and 401-405 can be implemented individually or in combination.

[0149] In this way, by controlling the operating frequency of the compressor and / or the opening of the throttling device, condensation can be prevented from forming in the air duct of the air conditioning equipment, ensuring the safety of the air conditioning equipment, reducing the possibility of bacterial growth, and improving the user experience.

[0150] It should be noted that the descriptions of the same steps and contents as in other embodiments in this embodiment can be found in the descriptions in other embodiments, and will not be repeated here.

[0151] In this embodiment, when the air conditioning equipment is operating in a multi-temperature cooling mode, the temperature parameters of the evaporators corresponding to m target valves that are in a closed state are obtained to obtain m first reference temperature parameters. The temperature parameters of n evaporators in the air conditioning equipment (excluding those corresponding to the m target valves) are obtained to obtain n second reference temperature parameters. The environmental parameters of the current environment in which the air conditioning equipment is located are also obtained. Finally, based on the m first reference temperature parameters, n second reference temperature parameters, and environmental parameters, the reference operating parameters of the air conditioning equipment are determined. Then, based on the current operating parameters and reference operating parameters, the target operating parameters of the air conditioning equipment are determined, and the operating parameters of the air conditioning equipment are switched to the target operating parameters.
