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

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:

[0015] 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.
[0016] The acquisition unit is also used to acquire environmental parameters of the environment in which the air conditioning equipment is currently located;
[0017] The determining unit is used to determine the target operating parameters of the air conditioning equipment based on m first reference temperature parameters, n second reference temperature parameters and the environmental parameters;

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0031] 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:
[0032] Step 101: Obtain the temperature parameters of the evaporators corresponding to the m target switch valves that are in the closed state, and obtain the m first reference temperature parameters.
[0033] 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.
[0034] In this embodiment, when the air conditioning equipment is operating in a multi-temperature cooling mode, m target switching valves can be controlled to be closed according to actual needs. This allows the air conditioning equipment to output airflow at multiple cold temperatures. Therefore, the closure of m target switching valves indicates whether the air conditioning equipment is in a multi-temperature cooling or multi-temperature heating mode. The target switching valve is a valve capable of controlling refrigerant flow; 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 conduction can be controlled by providing power to it. m can be the total number of switching valves in the air conditioning equipment used to control the flow of refrigerant through the evaporator. It should be noted that at this time, at least one evaporator in the air conditioning equipment should not have a switching valve for controlling the refrigerant flow. m can also refer to the number of on / off valves in an air conditioning unit used to control the flow rate of refrigerant through the evaporator. In this case, it could mean that all evaporators in the air conditioning unit are connected to the on / off valves used to control the flow rate of refrigerant, or it could mean that some evaporators in the air conditioning unit are connected to the on / off valves used to control the flow rate of refrigerant.
[0035] 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.
[0036] 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.
[0037] Where n is an integer greater than or equal to 1.
[0038] 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.
[0039] Step 103: Obtain the environmental parameters of the current environment in which the air conditioning equipment is located.
[0040] 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.
[0041] Step 104: Based on m first reference temperature parameters, n second reference temperature parameters, and environmental parameters, determine the target operating parameters of the air conditioning equipment.
[0042] 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 target operating parameters of the air conditioning equipment are determined.
[0043] Step 105: Switch the operating parameters of the air conditioning equipment to the target operating parameters.
[0044] 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.
[0045] In this embodiment, the temperature parameters of the evaporators corresponding to m target valves in a closed state are obtained to obtain m first reference temperature parameters. The temperature parameters of n evaporators in the air conditioning unit (excluding those corresponding to the m target valves) are also obtained to obtain n second reference temperature parameters. Furthermore, the environmental parameters of the current environment in which the air conditioning unit is located are acquired. Finally, based on the m first reference temperature parameters, the n second reference temperature parameters, and the environmental parameters, the target operating parameters of the air conditioning unit are determined, and the operating parameters of the air conditioning unit are switched to the target operating parameters. Thus, when the air conditioning unit is operating in a multi-temperature cooling mode, the operating parameters of the air conditioning unit 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 unit, the occurrence of condensation can be reduced, solving the problem of condensation that easily occurs when the air conditioning unit is in a multi-temperature cooling mode. This proposes an anti-condensation control method, reducing the probability of condensation in the air conditioning unit and ensuring the quality of the air conditioning unit.
[0046] 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:
[0047] Step 201: Obtain the temperature parameters of the evaporators corresponding to the m target switch valves that are in the closed state, and obtain the m first reference temperature parameters.
[0048] 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.
[0049] In this embodiment, temperature parameters are collected by a temperature sensor installed on each evaporator to obtain the first reference temperature parameters of the evaporator corresponding to the m target switching valves in the closed state. The m target switching valves in the closed state include switching valves that are completely closed and switching valves that are not completely closed. That is, the m target switching valves in the closed state include switching valves with an opening degree of 0 and / or switching valves with an opening degree greater than 0 but less than the maximum opening degree.
[0050] 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 3The 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.
[0051] 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.
[0052] Where n is an integer greater than or equal to 1.
[0053] 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.
[0054] Step 203: Obtain the environmental parameters of the current environment in which the air conditioning equipment is located.
[0055] In this embodiment of the application, the environmental parameters of the current environment of the 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.
[0056] For example, environmental parameters can be collected by an environmental parameter acquisition device installed on the air conditioning equipment. When the environmental parameter is, for example, the environmental humidity parameter, it can be collected by a humidity sensor.
[0057] Step 204: Determine the first target temperature parameter based on m first reference temperature parameters.
[0058] 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.
[0059] 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.
[0060] Step 205: Determine the second target temperature parameter based on n second reference temperature parameters.
[0061] 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.
[0062] 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.
[0063] Step 206: Determine the target operating parameters based on the first target temperature parameter, the second target temperature parameter, and the environmental parameters.
[0064] 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, the target operating parameters are determined. The target operating parameters may be the duration for which m target switching valves in the air conditioning equipment are in the closed state and the duration for which m target switching valves are switched to the conducting state and remain in the conducting state, etc.
[0065] For example, target 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.
[0066] Step 207: Switch the operating parameters of the air conditioning equipment to the target operating parameters.
[0067] 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.
[0068] Based on the foregoing embodiments, in other embodiments of this application, step 204 can be implemented by step 204a or steps 204b to 204c:
[0069] 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.
[0070] 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.
[0071] 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.
[0072] Step 204c: Determine the first target temperature parameter based on at least one third reference temperature parameter.
[0073] In the embodiments of this application, at least one third reference temperature parameter can be averaged to obtain the first target temperature parameter.
[0074] Based on the foregoing embodiments, in other embodiments of this application, step 205 can be implemented by step 205a or steps 205b to 205c:
[0075] Step 205a: From the n second reference temperature parameters, determine the temperature parameter with the smallest value to obtain the second target temperature parameter.
[0076] 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.
[0077] 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.
[0078] Step 205c: Determine the second target temperature parameter based on at least one fourth reference temperature parameter.
[0079] 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.
[0080] Based on the foregoing embodiments, in other embodiments of this application, step 206 can be implemented by steps 206a to 206b:
[0081] Step 206a: Determine the target difference between the first target temperature parameter and the second target temperature parameter.
[0082] 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.
[0083] Step 206b: Determine the target operating parameters based on the target difference and environmental parameters.
[0084] In this embodiment of the application, the target difference and environmental parameters are analyzed to determine the target operating parameters.
[0085] Based on the foregoing embodiments, in other embodiments of this application, step 206b can be implemented by steps a11 to a13:
[0086] Step a11: Determine the preset relationship between temperature changes and ambient humidity parameters and the state changes of the target switching valve.
[0087] In the embodiments of this application, the preset relationship can be an empirical relationship obtained from a large number of experiments. Under the multi-temperature mode of cooling, when different temperature changes in the output airflow of different air conditioning equipment correspond to different environmental humidity parameters, the switch valve is in the closed state for a certain period of time, and when the switch valve is controlled to be in the open state, it is in the open state for a certain period of time, so that the air conditioning equipment will not have condensation. Specifically, it can be represented in the form of a list or in the form of an empirical formula.
[0088] Step a12: Determine a first reference duration from the preset relationship to keep the target switch valve in the closed state, which matches the target difference and the current humidity parameter.
[0089] Among them, environmental parameters include the current humidity parameter.
[0090] In this embodiment, based on the determined target difference and the current humidity parameter in the environmental parameters, a first reference duration is determined from a preset relationship when the target switch valve is in the closed state to achieve the multi-temperature cooling operation mode. The current humidity parameter is the humidity parameter of the environment in which the air conditioning equipment is currently located, and is the same as the aforementioned environmental humidity parameter.
[0091] For example, if the preset relationship is an empirical formula, the target difference and the current humidity parameter are substituted into the preset relationship, and the first reference duration when the target switch valve is in the closed state is calculated.
[0092] Step a13: Determine a second reference duration from the preset relationship to keep the target switch valve in the conducting state, which matches the target difference and the current humidity parameter.
[0093] In this embodiment of the application, based on the determined target difference and the current humidity parameter in the environmental parameters, a second reference duration is determined from the preset relationship when the target switch valve is in the conducting state to realize the multi-temperature cooling working mode.
[0094] For example, if the preset relationship is in the form of a list, the second reference duration when the target switch valve is in the on state is obtained by looking up the duration corresponding to the target difference and the current humidity parameter from the list.
[0095] Based on the foregoing embodiments, in other embodiments of this application, step 207 can be implemented by steps 207a to 207b:
[0096] Step 207a: Control m target switching valves to be in the closed state for the first reference duration.
[0097] In this embodiment, the m target switching valves are controlled to be in the closed state for a first reference time to enable the air conditioning equipment to operate in a multi-temperature cooling mode. In some application scenarios, after the m target switching valves are controlled to be in the closed state for a first reference time, the m target switching valves are switched to the open state to enable the air conditioning equipment to switch to the cooling mode.
[0098] Step 207b: Control m target switching valves to be in the on state for the second reference time.
[0099] In this embodiment, the air conditioning device is controlled to be in the cooling mode for a second reference duration. In this way, during the application process after the air conditioning device receives the instruction of the multi-temperature cooling working mode, it continuously switches between the multi-temperature cooling working mode and the cooling mode. This can ensure the user's needs for the multi-temperature cooling mode, while preventing condensation from occurring on the air conditioning device, thus effectively improving the quality of use of the air conditioning device.
[0100] Based on the foregoing embodiments, in other embodiments of this application, after the air conditioning device performs step 207b, it is further configured to perform step 207c:
[0101] Step 207c: Execute the step of obtaining the temperature parameters of the evaporators corresponding to the m target switch valves that are in the closed state, and obtaining the m first reference temperature parameters, until an exit command for indicating exiting the multi-temperature working mode of refrigeration is received.
[0102] In this embodiment of the application, after controlling m target switching valves to be in the conducting state for a second reference time, the m target switching valves are then controlled to be in the closed state, that is, switched to the cooling multi-temperature working mode. Steps 201 to 207 and the corresponding specific implementation process are repeated until an exit command to exit the cooling multi-temperature working mode is received, and the above-mentioned cycle operation ends.
[0103] Based on the foregoing embodiments, in other embodiments of this application, reference is made to... Figure 5 As shown, before the air conditioning equipment performs step 201, it is also used to perform steps 208 to 209:
[0104] Step 208: If the air conditioning equipment receives a control command indicating to switch to the multi-temperature cooling mode, switch to the multi-temperature cooling mode.
[0105] In this embodiment, the control command received by the air conditioning device can be obtained by pressing a physical or virtual button on the indoor unit of the air conditioning device, or it can be sent by a remote control device for controlling the air conditioning device, such as a remote controller, or it can be sent by a controller for controlling the air conditioning device, such as a smart home central control device or a smart mobile terminal device. After receiving the control command indicating the switch to the multi-temperature cooling working mode, the air conditioning device responds to the control command and controls the air conditioning device to switch to the multi-temperature cooling working mode. Specifically, it switches the m target switching valves connected to the evaporator in the air conditioning device from the open state to the closed state, so that the corresponding refrigerant does not pass through the evaporator.
[0106] To ensure a good user experience, air conditioning units can simultaneously output cold air at different temperatures during cooling. This can be achieved by replacing one evaporator in the indoor unit with at least two evaporators and installing on / off valves on each evaporator to control the refrigerant passing through each evaporator. This allows the air conditioning unit to output air at different temperatures through each evaporator when it is in cooling mode.
[0107] 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.
[0108] Taking the example of sending control commands to air conditioning equipment via a remote control device, the user operates the remote control device according to their needs, causing the remote control device to send control commands to the air conditioning equipment. When the air conditioning equipment receives the control commands, it responds to the control commands and switches the air conditioning equipment to the multi-temperature cooling working mode.
[0109] Step 209: After switching to the multi-temperature cooling working mode, start the timer.
[0110] In this embodiment, a timer is used for timing. After switching to the multi-temperature cooling operating mode, the timer is controlled to keep track of the time.
[0111] Correspondingly, step 201 can be implemented by step 201a:
[0112] Step 201a: When the timer is set to the preset duration, obtain the temperature parameters of the evaporators corresponding to the m target switch valves that are in the closed state, and obtain the m first reference temperature parameters.
[0113] 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.
[0114] Steps 201 to 207 are executed only after the air conditioning equipment has been switched to the multi-temperature cooling mode for a preset time, which can effectively reduce the computational burden.
[0115] Based on the foregoing embodiments, this application provides an application embodiment of an anti-condensation control method, wherein the air conditioning equipment is in the following condition: Figure 3 The dual-temperature cooling operating mode shown is for reference. Figure 6 As shown, it includes the following steps:
[0116] Step 301: When the air conditioning unit switches to the dual-temperature cooling mode, start timing.
[0117] Step 302: When the timing duration is x hours, 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.
[0118] The duration x can be, for example, 5 minutes. This way, the temperature parameters of evaporator 1 and evaporator 2 are collected and analyzed only after the air conditioning unit has switched to the dual-temperature cooling mode for x duration, ensuring that the air conditioning unit is operating stably in the dual-temperature cooling mode and that the collected temperature parameters are more accurate.
[0119] Step 303: Calculate T = T2 - T1.
[0120] Step 304: Use a lookup table to find the first duration for which the normally open solenoid valve connected to the evaporator 1 is kept closed and the second duration for which the normally open solenoid valve is kept open from the preset relationship corresponding to T and S.
[0121] The preset relationships include Table 1 and Table 2. Table 1 shows the distribution of different durations for which the normally open solenoid valve connected to evaporator 1 is kept in the closed state for different T and different S values. Table 2 shows the distribution of different durations for which the normally open solenoid valve connected to evaporator 1 is kept in the open state for different T and different S values.
[0122] In some application scenarios, Table 1 of the preset relationship can also be expressed as Tamn = Ta(T, S), where T and Tamn are negatively correlated, and S is negatively correlated with Tamn, where m = 1, 2, ..., 6, and n = 1, 2, ..., 7. Table 2 of the preset relationship can also be expressed as Tbmn = Ta(T, S), where T and Tbmn are positively correlated, and S is positively correlated with Tbmn, where m = 1, 2, ..., 6, and n = 1, 2, ..., 7. It should be noted that whether the preset relationship is in list form or in the form of a calculated expression, 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 component control method. Different air conditioning equipment has different corresponding first preset relationships, which need to be determined by experimental testing and fitting based on the manufacturer's system configuration.

[0127] For example, if T is 5°C and S is 35%, then the first duration for which the normally open solenoid valve is in the closed state is determined from Table 1 as Ta62, and the second duration for which the normally open solenoid valve is in the open state is determined from Table 2 as Tb62.
[0128] Step 305: After keeping the normally open solenoid valve in the closed state for a first duration, control the normally open solenoid valve to be in the open state and keep the normally open solenoid valve in the open state for a second duration, and then execute step 301 again.
[0129] For example, after keeping the normally open solenoid valve in the closed state for Ta62 seconds, the normally open solenoid valve is controlled to be in the open state and held for Tb62 seconds. That is, the switching command for controlling the air conditioning equipment to switch to the dual-temperature cooling mode can be automatically generated by the air conditioning equipment after keeping the normally open solenoid valve in the open state for Tb62 seconds.
[0130] In this way, by controlling the duration of the on / off valve used to control whether the refrigerant passes through the evaporator in the closed or open state, condensation in the air duct of the air conditioning equipment can be prevented, ensuring the safety of the air conditioning equipment, reducing the possibility of bacterial growth, and improving the user experience.
[0131] 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.
[0132] In this embodiment, by acquiring the temperature parameters of the evaporators corresponding to m target switching valves in a closed state, m first reference temperature parameters are obtained. Additionally, by acquiring the temperature parameters of n evaporators in the air conditioning unit (excluding those corresponding to the m target switching valves), n second reference temperature parameters are obtained. Furthermore, the environmental parameters of the current environment in which the air conditioning unit is located are acquired. Finally, based on the m first reference temperature parameters, n second reference temperature parameters, and environmental parameters, the target operating parameters of the air conditioning unit are determined, and the operating parameters of the air conditioning unit are switched to the target operating parameters. Thus, when the air conditioning unit is operating in a multi-temperature cooling mode, the operating parameters of the air conditioning unit are determined using the temperatures of the evaporators corresponding to the m target switching 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 unit, the occurrence of condensation can be reduced, solving the problem of condensation easily occurring when the air conditioning unit is in a multi-temperature cooling mode. This proposes an anti-condensation control method, reducing the probability of condensation in the air conditioning unit and ensuring the quality of the air conditioning unit.
