[0001] This invention relates to the field of air conditioning equipment technology, and more specifically, to a water valve adjustment method and device, a heat exchange device, an air conditioning device, and a storage medium. Background Technology

[0002] In existing technologies, the opening of the coil water valve is typically adjusted proportionally. However, for water valves with non-linear flow characteristic curves, adjusting the valve opening proportionally can lead to a mismatch between the valve opening adjustment and the flow rate adjustment. This results in either an excessively small or excessively large opening adjustment, reducing the accuracy of the valve opening adjustment and consequently decreasing the accuracy of the air conditioning supply temperature control during subsequent air conditioning operation. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, the first aspect of the present invention is to provide a method for adjusting a water valve.

[0005] A second aspect of the invention is to provide a regulating device for a water valve.

[0006] A third aspect of the invention is to provide a regulating device for a water valve.

[0007] A fourth aspect of the present invention is to provide a heat exchange device.

[0008] The fifth aspect of the present invention is to provide an air conditioning device.

[0009] The sixth aspect of the present invention is to provide a readable storage medium.

[0010] In view of this, according to one aspect of the present invention, a method for adjusting a water valve is proposed, the method comprising: determining a second mapping relationship between an opening adjustment value and a flow adjustment value based on a first mapping relationship between a flow rate value and an opening value of the water valve; determining a target opening adjustment value based on a current opening value, a target flow adjustment value, and the second mapping relationship; and adjusting the opening of the water valve based on the target opening adjustment value.

[0011] The subject of execution of the water valve adjustment method provided by this invention can be the water valve adjustment device, or it can be determined according to actual usage requirements, and is not specifically limited here. In order to more clearly describe the water valve adjustment method provided by this invention, the following description uses the water valve adjustment device as the subject of execution of the water valve adjustment method.

[0012] Specifically, in the water valve adjustment method proposed in this invention, during the process of adjusting the opening value of the water valve, a first mapping relationship between the opening value of the water valve and the flow rate value of the water valve is first determined. Then, based on the first mapping relationship, a second mapping relationship between the flow rate adjustment amount of the water valve and the opening value adjustment amount of the water valve is determined. Then, based on the determined second mapping relationship, the target flow rate adjustment amount of the water valve, and the current opening value of the water valve, the target opening value adjustment amount of the water valve is determined, and the opening of the water valve is adjusted according to the target opening value adjustment amount.

[0013] It is understood that the second mapping relationship between the flow rate adjustment and the opening adjustment of the water valve can also be used to characterize the correspondence between the flow rate change rate and the opening rate change rate of the water valve. Based on this, in the water valve adjustment method proposed in this invention, when adjusting the opening value of the water valve in conjunction with the above-mentioned second mapping relationship, the opening adjustment amount of the water valve can be corrected by combining the correspondence between the flow rate change rate and the opening rate change rate of the water valve. This ensures a high degree of matching between the opening adjustment amount and the flow rate adjustment amount of the water valve, avoiding problems such as excessively small or large opening adjustment amounts, improving the accuracy of water valve opening adjustment, and consequently improving the accuracy of air conditioning supply temperature regulation during subsequent air conditioning operation.

[0014] In summary, the water valve adjustment method proposed in this invention corrects the valve opening adjustment amount by combining the correspondence between the flow rate change rate and the opening rate change rate of the water valve. This ensures a high degree of matching between the valve opening adjustment amount and the flow rate adjustment amount, avoiding problems such as the valve opening adjustment amount being too small or too large, thus improving the accuracy of the water valve opening adjustment. Consequently, it improves the accuracy of air conditioner supply air temperature regulation during subsequent air conditioner operation.

[0015] The water valve adjustment method according to the present invention may further include the following additional technical features:

[0016] In the above technical solution, determining the second mapping relationship between the opening adjustment value and the flow adjustment value based on the first mapping relationship between the flow rate value and the opening value of the water valve includes: determining the flow characteristic function of the water valve based on the first mapping relationship; determining the target adjustment function based on the flow characteristic function; and determining the second mapping relationship based on the target adjustment function.

[0017] In this technical solution, during the determination of the second mapping function, the flow characteristic function of the water valve is first determined through the first mapping relationship. This flow characteristic function is the specific functional form of the flow characteristic curve of the water valve, which can express the correspondence between the opening value and the flow value of the water valve. Based on this, a target adjustment function is determined according to the determined flow characteristic function. This target adjustment function can be used to characterize the correspondence between the change in flow rate and the change in opening value of the water valve. Furthermore, based on the correspondence between the change in flow rate and the change in opening value of the water valve, that is, based on the aforementioned target adjustment function, the second mapping relationship between the flow rate adjustment amount and the opening adjustment amount of the water valve is determined.

[0018] In this way, during the adjustment of the water valve opening value, the corresponding relationship between the water valve flow rate change value and the opening value change value can be combined to correct the water valve opening adjustment value, thereby ensuring a high degree of matching between the water valve opening adjustment amount and the flow rate adjustment amount. This avoids the problem of the water valve opening adjustment amount being too small or too large, improves the accuracy of water valve opening adjustment, and consequently improves the accuracy of air conditioning supply temperature regulation during subsequent air conditioning operation.

[0019] In any of the above technical solutions, determining the target adjustment function based on the flow characteristic function includes: determining the first derivative of the flow characteristic function with respect to the water valve flow rate, and the second derivative of the flow characteristic function with respect to the water valve opening; determining the target derivative function of the flow characteristic function based on the first derivative and the second derivative; and determining the target adjustment function based on the target derivative function.

[0020] In this technical solution, during the process of determining the target adjustment function through the flow characteristic function of the water valve, the target adjustment function can be determined by taking the derivative of the flow characteristic function, in order to ensure the accuracy of the determination of the second mapping relationship.

[0021] Specifically, the aforementioned flow characteristic function can be a functional equation with the water valve opening value as the independent variable and the water valve flow rate value as the dependent variable. Based on this, after determining the flow characteristic function of the water valve, the equation on both sides of the flow characteristic function equation can be differentiated simultaneously to obtain the objective differential expression of the aforementioned flow characteristic function. This objective differential expression includes the first differential expression of the aforementioned flow characteristic function relative to the water valve flow rate value, and the second differential expression of the aforementioned flow characteristic function relative to the water valve opening value.

[0022] Furthermore, during the adjustment of the water valve opening, the aforementioned target flow rate adjustment value is a known quantity. Therefore, after determining the aforementioned target differential expression, it can be transformed into a target derivative function with the differential of the opening value as the dependent variable and the differential of the flow rate value as the independent variable.

[0023] It is understandable that in the above objective derivative function, the derivative of the water valve opening value can characterize the change in the water valve opening value within an infinitesimal time interval, that is, the rate of change of the water valve opening value. Similarly, the derivative of the water valve flow rate value can characterize the change in the water valve flow rate value within an infinitesimal time interval, that is, the rate of change of the water valve flow rate value. Therefore, the derivative of the water valve opening value in the above objective derivative function can be used as the opening adjustment value, and the derivative of the water valve flow rate value can be used as the flow rate adjustment value. The objective derivative function is thus transformed into an objective adjustment function that characterizes the correspondence between the water valve opening adjustment value and the flow rate adjustment value.

[0024] In any of the above technical solutions, determining the target opening adjustment value based on the current opening value, the target flow adjustment value, and the second mapping relationship includes: substituting the current opening value and the target flow adjustment value into the target adjustment function corresponding to the second mapping relationship to obtain the target opening adjustment value.

[0025] In this technical solution, the aforementioned target adjustment function corresponds to the aforementioned second mapping relationship. This target adjustment function can be used to characterize the correspondence between the water valve's opening adjustment value and flow adjustment value, that is, to characterize the aforementioned second mapping relationship. Based on this, in this technical solution, the current opening value and target flow adjustment value of the water valve are obtained. After determining the target adjustment function corresponding to the second mapping relationship, the obtained current opening value and target flow adjustment value of the water valve are substituted into the aforementioned target adjustment function to obtain the target opening adjustment value of the water valve. In this way, the opening adjustment value of the water valve can be corrected by considering the rate of change of the water valve's flow adjustment value relative to the water valve's opening adjustment value at the current opening value, thereby ensuring the accuracy of determining the target opening adjustment value of the water valve, and thus ensuring the accuracy of the air conditioning supply temperature adjustment during subsequent air conditioning operation.

[0026] In any of the above technical solutions, adjusting the opening of the water valve according to the target opening adjustment value includes: determining the target opening value based on the current opening value and the target opening adjustment value; and adjusting the opening of the water valve from the current opening value to the target opening value.

[0027] In this technical solution, after determining the target opening adjustment value of the water valve, the current opening value of the water valve is used as a reference. The opening value of the water valve is increased or decreased by the target opening adjustment value to obtain the target opening value of the water valve. This target opening value corresponds to the target supply air temperature of the air conditioning equipment. Based on this, adjusting the opening value of the water valve from the current opening value to the target opening value will adjust the supply air temperature of the air conditioning equipment to the target supply air temperature to meet the user's air supply needs.

[0028] According to a second aspect of the present invention, a water valve regulating device is provided, the device comprising: a processing unit configured to determine a second mapping relationship between an opening regulation value and a flow regulation value based on a first mapping relationship between a flow rate value and an opening value of the water valve; the processing unit is further configured to determine a target opening regulation value based on a current opening value, a target flow regulation value, and the second mapping relationship; and the processing unit is further configured to adjust the opening of the water valve according to the target opening regulation value.

[0029] The water valve adjustment device proposed in this invention includes a processing unit. In the process of adjusting the opening value of the water valve, the processing unit first determines a first mapping relationship between the opening value of the water valve and the flow rate value of the water valve. Then, the processing unit determines a second mapping relationship between the flow rate adjustment amount and the opening value adjustment amount of the water valve based on the first mapping relationship. Then, the processing unit determines the target opening value adjustment amount of the water valve based on the determined second mapping relationship, the target flow rate adjustment amount of the water valve, and the current opening value of the water valve, and adjusts the opening of the water valve according to the target opening value adjustment amount.

[0030] It is understood that the second mapping relationship between the flow rate adjustment and the opening adjustment of the water valve can also be used to characterize the correspondence between the flow rate change rate and the opening rate change rate of the water valve. Based on this, in the water valve adjustment device proposed in this invention, when the processing unit adjusts the opening value of the water valve in conjunction with the above-mentioned second mapping relationship, it can correct the opening adjustment amount of the water valve by combining the correspondence between the flow rate change rate and the opening rate change rate of the water valve. This ensures a high degree of matching between the opening adjustment amount and the flow rate adjustment amount of the water valve, avoiding problems such as the opening adjustment amount being too small or too large, improving the accuracy of the water valve opening adjustment, and consequently improving the accuracy of the air conditioning supply temperature adjustment during subsequent air conditioning operation.

[0031] In summary, the water valve regulating device proposed in this invention allows the processing unit to correct the water valve opening adjustment amount by combining the correspondence between the flow rate change rate and the opening rate change rate of the water valve. This ensures a high degree of matching between the water valve opening adjustment amount and the flow rate adjustment amount, avoiding problems such as the water valve opening adjustment amount being too small or too large, improving the accuracy of water valve opening adjustment, and consequently improving the accuracy of air conditioning supply temperature regulation during subsequent air conditioning operation.

[0032] The regulating device for the water valve according to the present invention may further have the following additional technical features:

[0033] In the above technical solution, the processing unit is specifically used to: determine the flow characteristic function of the water valve according to the first mapping relationship; determine the target adjustment function according to the flow characteristic function; and determine the second mapping relationship according to the target adjustment function.

[0034] In this technical solution, during the process of the processing unit determining the second mapping function, the flow characteristic function of the water valve is first determined through the first mapping relationship. This flow characteristic function is a specific functional form of the flow characteristic curve of the water valve, which can express the correspondence between the opening value and the flow value of the water valve. Based on this, the processing unit determines a target adjustment function according to the determined flow characteristic function. This target adjustment function can be used to characterize the correspondence between the flow change value and the opening change value of the water valve. Based on this, the processing unit then determines the second mapping relationship between the flow adjustment amount and the opening adjustment amount of the water valve according to the correspondence between the flow change value and the opening change value of the water valve, that is, according to the target adjustment function.

[0035] In this way, during the process of the processing unit adjusting the opening value of the water valve, the corresponding relationship between the change in the flow rate and the change in the opening value of the water valve can be combined to correct the adjustment value of the water valve opening. This ensures a high degree of matching between the adjustment amount of the water valve opening and the adjustment amount of the flow rate, avoiding the problem of the water valve opening adjustment amount being too small or too large, improving the accuracy of the water valve opening adjustment, and thus improving the accuracy of the air supply temperature adjustment in the subsequent air conditioning operation.

[0036] In any of the above technical solutions, the processing unit is specifically used to: determine the first derivative of the flow characteristic function with respect to the water valve flow rate, and the second derivative of the flow characteristic function with respect to the water valve opening degree; determine the target derivative function of the flow characteristic function based on the first derivative and the second derivative; and determine the target adjustment function based on the target derivative function.

[0037] In this technical solution, during the process of the processing unit determining the target adjustment function through the flow characteristic function of the water valve, the target adjustment function can be determined by taking the derivative of the flow characteristic function, in combination with the principle characteristics of the function, so as to ensure the accuracy of the determination of the second mapping relationship.

[0038] Specifically, the aforementioned flow characteristic function can be a functional equation with the water valve opening value as the independent variable and the water valve flow rate value as the dependent variable. Based on this, after determining the flow characteristic function of the water valve, the equation on both sides of the flow characteristic function equation can be differentiated simultaneously to obtain the objective differential expression of the aforementioned flow characteristic function. This objective differential expression includes the first differential expression of the aforementioned flow characteristic function relative to the water valve flow rate value, and the second differential expression of the aforementioned flow characteristic function relative to the water valve opening value.

[0039] Furthermore, during the adjustment of the water valve opening, the aforementioned target flow rate adjustment value is a known quantity. Therefore, after determining the aforementioned target differential expression, it can be transformed into a target derivative function with the opening value as the dependent variable.

[0040] It is understandable that in the above objective derivative function, the derivative of the water valve opening value can characterize the change in the water valve opening value within an infinitesimal time interval, that is, the rate of change of the water valve opening value. Similarly, the derivative of the water valve flow rate value can characterize the change in the water valve flow rate value within an infinitesimal time interval, that is, the rate of change of the water valve flow rate value. Therefore, the derivative of the water valve opening value in the above objective derivative function can be used as the opening adjustment value, and the derivative of the water valve flow rate value can be used as the flow rate adjustment value. The objective derivative function is thus transformed into an objective adjustment function that characterizes the correspondence between the water valve opening adjustment value and the flow rate adjustment value.

[0041] In any of the above technical solutions, the processing unit is specifically used to: substitute the current opening value and the target flow adjustment value into the target adjustment function corresponding to the second mapping relationship to obtain the target opening adjustment value.

[0042] In this technical solution, the aforementioned target adjustment function corresponds to the aforementioned second mapping relationship. This target adjustment function can be used to characterize the correspondence between the water valve's opening adjustment value and flow adjustment value, that is, to characterize the aforementioned second mapping relationship. Based on this, in this technical solution, the processing unit can also obtain the current opening value and target flow adjustment value of the water valve. After determining the target adjustment function corresponding to the second mapping relationship, the obtained current opening value and target flow adjustment value of the water valve are substituted into the aforementioned target adjustment function to obtain the target opening adjustment value of the water valve. In this way, the opening adjustment value of the water valve can be corrected by combining the rate of change of the water valve's flow adjustment value relative to the water valve's opening adjustment value at the current opening value, thereby ensuring the accuracy of determining the target opening adjustment value of the water valve, and thus ensuring the accuracy of the air conditioning supply temperature adjustment during subsequent air conditioning operation.

[0043] In any of the above technical solutions, the processing unit is specifically used to: determine the target opening value based on the current opening value and the target opening adjustment value; and adjust the opening of the water valve from the current opening value to the target opening value.

[0044] In this technical solution, after the processing unit determines the target opening adjustment value of the water valve, it increases or decreases the target opening adjustment value of the water valve based on the current opening value of the water valve to obtain the target opening value of the water valve. This target opening value corresponds to the target supply air temperature of the air conditioning equipment. Based on this, the processing unit adjusts the opening value of the water valve from the current opening value to the target opening value, thereby adjusting the supply air temperature of the air conditioning equipment to the target supply air temperature to meet the user's air supply needs.

[0063] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0064] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0065] The following is combined Figures 1 to 11 The present application provides a detailed description of the water valve adjustment method and device, heat exchange device, air conditioning equipment and storage medium provided in the embodiments of this application through specific implementation methods and application scenarios.

[0066] Example 1, Figure 1 A schematic flowchart of a water valve adjustment method according to an embodiment of the present invention is shown. Specifically, the adjustment method may include the following steps S102 to S106:

[0067] S102, based on the first mapping relationship between the flow rate value and the opening value of the water valve, determine the second mapping relationship between the opening adjustment value and the flow rate adjustment value;

[0068] S104, determine the target opening adjustment value based on the current opening value, the target flow adjustment value, and the second mapping relationship;

[0069] S106, adjust the opening of the water valve according to the target opening adjustment value.

[0070] The subject of execution of the water valve adjustment method provided by this invention can be the water valve adjustment device, or it can be determined according to actual usage requirements, and is not specifically limited here. In order to more clearly describe the water valve adjustment method provided by this invention, the following description uses the water valve adjustment device as the subject of execution of the water valve adjustment method.

[0071] In the water valve adjustment method proposed in this invention, during the process of adjusting the opening value of the water valve, a first mapping relationship between the opening value of the water valve and the flow rate value of the water valve is first determined. Then, based on the first mapping relationship, a second mapping relationship between the flow rate adjustment amount of the water valve and the opening value adjustment amount of the water valve is determined. Then, based on the determined second mapping relationship, the target flow rate adjustment amount of the water valve, and the current opening value of the water valve, the target opening value adjustment amount of the water valve is determined, and the opening of the water valve is adjusted according to the target opening value adjustment amount.

[0072] It is understood that the second mapping relationship between the flow rate adjustment and the opening adjustment of the water valve can also be used to characterize the correspondence between the flow rate change rate and the opening rate change rate of the water valve. Based on this, in the water valve adjustment method proposed in this invention, when adjusting the opening value of the water valve in conjunction with the above-mentioned second mapping relationship, the opening adjustment amount of the water valve can be corrected by combining the correspondence between the flow rate change rate and the opening rate change rate of the water valve. This ensures a high degree of matching between the opening adjustment amount and the flow rate adjustment amount of the water valve, avoiding problems such as excessively small or large opening adjustment amounts, improving the accuracy of water valve opening adjustment, and consequently improving the accuracy of air conditioning supply temperature regulation during subsequent air conditioning operation.

[0073] The first mapping relationship mentioned above can be determined based on the flow characteristic curve of the water valve, which is a curve characterizing the correspondence between the valve opening value and the flow rate value. In practical applications, the flow characteristic curve can be pre-stored in the storage space of the water valve's regulating device, and can be directly retrieved and used during the adjustment of the valve opening. Alternatively, the flow characteristic curve can be obtained from the water valve specification diagram or through multiple experimental tests. Those skilled in the art can set it according to the actual situation, and no specific limitations are imposed here.

[0074] Furthermore, the aforementioned second mapping relationship can also be used to characterize the correspondence between the rate of change of flow rate and the rate of change of opening of the water valve. In practical applications, the aforementioned second mapping relationship can be specifically determined through the derivative function of the flow characteristic curve of the water valve. Based on this, combined with the current opening value of the water valve and the aforementioned second mapping relationship, the rate of change of the water valve opening at the current opening value can be determined. Then, the water valve opening adjustment amount can be corrected according to this rate of change, so that the water valve opening adjustment amount can match the flow rate adjustment amount, thereby ensuring the accuracy of the water valve opening adjustment.

[0075] Furthermore, in the process of adjusting the opening value of the water valve to regulate the air supply temperature of the air conditioning unit, the aforementioned target flow rate adjustment value is a known quantity, and this target flow rate adjustment value corresponds to the target air supply temperature of the air conditioning unit. Specifically, during the operation of the air conditioning unit, the current air supply temperature of the air conditioning unit and the target air supply temperature set by the user can be obtained, and then the temperature difference between the current air supply temperature and the target air supply temperature can be determined. Based on this temperature difference, the required target flow rate adjustment value is determined. On this basis, after adjusting the opening value of the water valve according to the determined target flow rate adjustment value, the air supply temperature of the air conditioning unit can be adjusted to the aforementioned target air supply temperature.

[0076] In summary, the water valve adjustment method proposed in this invention determines the second mapping relationship between the water valve's flow rate adjustment and its opening adjustment based on the first mapping relationship between the valve's opening value and flow rate, as represented by the valve's flow characteristic curve. This means determining the correspondence between the valve's flow rate change rate and its opening rate change rate. Furthermore, by combining this correspondence, the valve's opening adjustment is corrected, ensuring a high degree of matching between the opening adjustment and flow rate adjustment. This avoids problems of excessively small or large opening adjustments, improving the accuracy of the valve's opening adjustment and consequently enhancing the accuracy of air conditioning supply temperature regulation during subsequent air conditioning operation.

[0077] Example 2, Figure 2 A second schematic flowchart of a water valve adjustment method according to an embodiment of the present invention is shown. Specifically, this adjustment method may include the following steps S202 to S210:

[0078] S202, Based on the first mapping relationship between the flow rate value and the opening value of the water valve, the flow characteristic function of the water valve is determined;

[0079] S204, Determine the target adjustment function based on the flow characteristic function;

[0080] S206, Based on the target adjustment function, determine the second mapping relationship between the opening adjustment value and the flow adjustment value of the water valve;

[0081] S208, Determine the target opening adjustment value of the water valve based on the current opening value of the water valve, the second mapping relationship, and the target flow adjustment value;

[0082] S210, adjusts the opening of the water valve according to the target opening adjustment value.

[0083] In this embodiment, based on Embodiment 1, the specific method for determining the second mapping relationship between the flow rate adjustment and the opening adjustment of the water valve is further defined, based on the first mapping relationship between the opening value and the flow rate value of the water valve. Specifically, in determining the second mapping function, firstly, the flow characteristic function of the water valve is determined through the first mapping relationship. This flow characteristic function is a specific functional form of the flow characteristic curve of the water valve, which can express the correspondence between the opening value and the flow rate value of the water valve. Based on this, a target adjustment function is determined according to the determined flow characteristic function. This target adjustment function can be used to characterize the correspondence between the flow rate change value and the opening change value of the water valve. Based on this, the second mapping relationship between the flow rate adjustment and the opening adjustment of the water valve is determined according to the correspondence between the flow rate change value and the opening change value of the water valve, that is, according to the target adjustment function.

[0084] In this way, during the adjustment of the water valve opening value, the corresponding relationship between the water valve flow rate change value and the opening value change value can be combined to correct the water valve opening adjustment value, thereby ensuring a high degree of matching between the water valve opening adjustment amount and the flow rate adjustment amount. This avoids the problem of the water valve opening adjustment amount being too small or too large, improves the accuracy of water valve opening adjustment, and consequently improves the accuracy of air conditioning supply temperature regulation during subsequent air conditioning operation.

[0085] The flow characteristic function of the aforementioned water valve describes the correspondence between the valve's opening value and its flow rate. Specifically, this flow characteristic function can be a functional equation with the valve opening value as the independent variable and the flow rate value as the dependent variable. Furthermore, the aforementioned target adjustment function describes the correspondence between the change in the flow rate and the change in the valve's opening value. This target adjustment function can also be a functional equation with the change in flow rate as the independent variable and the change in opening value as the dependent variable. Based on this, and considering the fundamental characteristics of functions, the aforementioned target adjustment function can be obtained by differentiating the aforementioned flow characteristic function, thus ensuring the accuracy of the determination of the second mapping relationship.

[0087] S302, Based on the first mapping relationship between the flow rate value and the opening value of the water valve, the flow characteristic function of the water valve is determined;

[0088] S304, determine the first derivative of the flow characteristic function with respect to the water valve flow rate, and the second derivative of the flow characteristic function with respect to the water valve opening;

[0092] S312, Determine the target opening adjustment value of the water valve based on the current opening value of the water valve, the second mapping relationship, and the target flow adjustment value;

[0093] S314, adjusts the opening of the water valve according to the target opening adjustment value.

[0094] In this embodiment, based on Embodiment 2, the specific method for determining the target adjustment function using the flow characteristic function of the water valve is further defined. Specifically, in the process of determining the target adjustment function using the flow characteristic function of the water valve, combined with the principle characteristics of the function, the target adjustment function can be determined by differentiating the flow characteristic function to ensure the accuracy of the determination of the second mapping relationship.

[0095] Specifically, the above-mentioned flow characteristic function can be a functional equation with the water valve opening value as the independent variable and the water valve flow rate value as the dependent variable. In practical applications, the above-mentioned flow characteristic function can be expressed by the following formula (1):

[0096] Q=F(L) (1)

[0097] Where Q is the flow rate of the water valve, and L is the opening degree of the water valve.

[0098] Based on this, after determining the flow characteristic function of the water valve, the equations on both sides of the flow characteristic function equation can be differentiated simultaneously to obtain the target differential expression of the flow characteristic function. This target differential expression includes the first differential expression of the flow characteristic function relative to the water valve flow rate value, and the second differential expression of the flow characteristic function relative to the water valve opening value. In practical applications, the target differential expression can be specifically expressed by the following formula (2):

[0099] dQ=F'(L)dL (2)

[0100] Where dQ is the first differential of the flow characteristic function with respect to the flow rate Q of the water valve, F'(L)dL is the second differential of the flow characteristic function with respect to the opening value L of the water valve, F'(L) is the derivative of F(L) with respect to the opening value L of the water valve, and dL is the differential of the opening value L of the water valve.

[0101] Furthermore, during the adjustment of the water valve opening, the target flow rate adjustment value is known. Therefore, after determining the target differential equation, it can be transformed into a target derivative function with the differential dL of the opening value L as the dependent variable. That is, the equations on both sides of the equation are simultaneously divided by F'(L). In practical applications, the target derivative function can be specifically expressed by the following formula (3):

[0102] dL=dQ / F'(L) (3)

[0103] Where dL is the derivative of the valve opening value L, dQ is the derivative of the valve flow rate value Q, and F'(L) is the derivative of F(L) with respect to the valve opening value L.

[0104] It is understandable that in the above objective derivative function, dL is the differential of the water valve opening value L, which can characterize the change of the water valve opening value in an infinitely small time interval, that is, the rate of change of the water valve opening value; dQ is the differential of the water valve flow rate value Q, which can characterize the change of the water valve flow rate value in an infinitely small time interval, that is, the rate of change of the water valve flow rate value.

[0105] Based on this, the derivative dL of the water valve opening value L in the above target derivative function can be used as the opening adjustment value, and the derivative dQ of the water valve flow rate value Q can be used as the flow rate adjustment value. Thus, the target derivative function is transformed into a target adjustment function that characterizes the correspondence between the water valve opening adjustment value and the flow rate adjustment value. In practical applications, the above target adjustment function can be specifically expressed by the following formula (4):

[0106] △L=△Q / F'(L) (4)

[0107] Where △L is the valve opening adjustment value, △Q is the valve flow rate adjustment value, and F'(L) is the derivative of the valve flow characteristic function F(L) with respect to the valve opening value L. Example 4, Figure 4 The fourth schematic flowchart illustrates a water valve adjustment method according to an embodiment of the present invention. Specifically, this adjustment method may include the following steps S402 to S412:

[0108] S402, Based on the first mapping relationship between the flow rate value and the opening value of the water valve, the flow characteristic function of the water valve is determined;

[0109] S404, determine the first derivative of the flow characteristic function with respect to the water valve flow rate, and the second derivative of the flow characteristic function with respect to the water valve opening;

[0110] S406, Determine the objective derivative function of the flow characteristic function based on the second derivative and the first derivative;

[0111] S408, Determine the target adjustment function based on the target derivative function;

[0112] S410, Substitute the target flow rate adjustment value and the current opening value of the water valve into the target adjustment function to obtain the target opening adjustment value;

[0113] S412, adjusts the opening of the water valve according to the target opening adjustment value.

[0114] In this embodiment, based on the above embodiment, the specific method for determining the target opening adjustment value of the water valve through the second mapping relationship, the current opening value of the water valve, and the target flow adjustment value is further defined. Specifically, the target adjustment function corresponds to the second mapping relationship. This target adjustment function can be used to characterize the correspondence between the opening adjustment value and the flow adjustment value of the water valve, that is, to characterize the second mapping relationship. Based on this, in this embodiment, the current opening value and the target flow adjustment value of the water valve are obtained. After determining the target adjustment function corresponding to the second mapping relationship, the obtained current opening value and target flow adjustment value of the water valve are substituted into the target adjustment function to obtain the target opening adjustment value of the water valve.

[0115] It is understandable that the aforementioned target adjustment function is related to the valve opening adjustment value, the valve flow adjustment value, and the derivative of the valve flow characteristic function with respect to the valve opening value. Specifically, the derivative of the valve flow characteristic function with respect to the valve opening value can be used to characterize the rate of change of the valve flow rate relative to the valve opening value, that is, to characterize the rate of change of the valve flow adjustment value relative to the valve opening adjustment value. Based on this, the obtained current valve opening value and target flow adjustment value are substituted into the aforementioned target adjustment function to determine the target valve opening adjustment value. This allows for correction of the valve opening adjustment value by considering the rate of change of the valve flow adjustment value relative to the valve opening adjustment value at the current opening value, thereby ensuring the accuracy of determining the target valve opening adjustment value and ensuring the accuracy of air conditioning supply temperature regulation during subsequent air conditioning operation.

[0116] For example, when the current opening value of the water valve is L1, and the target flow rate adjustment value is △Q1 determined based on the current supply air temperature and the target supply air temperature of the air conditioning equipment, the target opening adjustment value △L1 of the water valve can be expressed by the following formula (5):

[0117] △L1=△Q1 / F'(L1) (5)

[0118] Where △L1 is the target opening adjustment value of the water valve, L1 is the current opening value of the water valve, △Q1 is the target flow adjustment value of the water valve, and F'(L1) is the derivative of the flow characteristic function of the water valve with respect to the opening value of the water valve at the current opening value.

[0119] Example 5, Figure 5 Fifthly, a schematic flowchart of a water valve adjustment method according to an embodiment of the present invention is shown. Specifically, this adjustment method may include the following steps S502 to S508:

[0120] S502, based on the first mapping relationship between the flow rate value and the opening value of the water valve, determine the second mapping relationship between the opening adjustment value and the flow rate adjustment value of the water valve;

[0121] S504, Determine the target opening adjustment value of the water valve based on the current opening value of the water valve, the second mapping relationship, and the target flow adjustment value;

[0122] S506, The target opening value of the water valve is determined based on the target opening adjustment value and the current opening value;

[0123] S508, adjust the opening degree of the water valve to the target opening degree value.

[0124] In this embodiment, based on the above embodiments, the specific method of adjusting the opening of the water valve by the target opening adjustment value of the water valve in the above embodiments is further defined. Specifically, after determining the target opening adjustment value of the water valve, the opening value of the water valve is increased or decreased by the target opening adjustment value based on the current opening value of the water valve to obtain the target opening value of the water valve. This target opening value corresponds to the target air supply temperature of the air conditioning equipment. Based on this, adjusting the opening value of the water valve from the current opening value to the target opening value can adjust the air supply temperature of the air conditioning equipment to the target air supply temperature to meet the user's air supply needs.

[0125] The aforementioned target opening adjustment value is obtained by correcting the water valve's opening adjustment value based on the rate of change of the water valve's flow rate adjustment value relative to its opening adjustment value at the current opening value. Therefore, adjusting the water valve's opening value using this target opening adjustment value ensures the accuracy of determining the target opening value, thereby guaranteeing a high degree of matching between the target opening value and the target supply air temperature. This, in turn, ensures the accuracy of supply air temperature regulation during subsequent air conditioning operation.

[0126] In summary, the water valve adjustment method provided by this invention is applicable to adjusting the opening degree of the water valve in a water coil air conditioner. During the operation of a water coil air conditioner, the water flow rate in the heat exchanger is changed primarily by adjusting the opening degree of the water valve in the water coil, thereby achieving the purpose of adjusting the air supply temperature of the water coil air conditioner. It can be understood that, given that the inlet and outlet water temperatures of the water coil are fixed, the direct factor affecting the air supply temperature of the water coil air conditioner is the water flow rate in the water coil, i.e., the opening degree of the water valve.

[0127] Currently, the water valve opening is typically adjusted proportionally based on the target flow rate of the water coil. However, for water valves with non-linear flow characteristic curves, a mismatch between the target opening adjustment and the target flow rate can occur when adjusting the valve opening using this proportional method. This leads to either an excessively small or excessively large adjustment, reducing the accuracy of the valve opening adjustment and consequently, the accuracy of the air conditioning supply temperature regulation.

[0128] For example, Figure 6 The flow characteristic curve of an equal percentage type water valve is shown, where both flow rate Q and opening L are expressed as dimensionless percentages. That is, flow rate Q represents the flow rate percentage, which is the ratio of the current flow rate to the maximum flow rate of the valve, and opening L represents the opening percentage, which is the ratio of the current opening value to the maximum opening value of the valve. Figure 6 It can be seen that for equal percentage type water valves, their flow characteristic curve exhibits a non-linear change, meaning that the changes in the valve's flow rate Q and opening value L are not linearly related. In this case, if the valve opening value is adjusted proportionally, when the flow rate is small, the rate of change in the flow rate is less than the rate of change in the valve opening value, resulting in insufficient flow adjustment (i.e., untimely flow regulation). Conversely, when the flow rate is large, the rate of change in the flow rate is greater than the rate of change in the valve opening value, resulting in excessive flow adjustment (i.e., excessively rapid flow regulation).

[0129] Furthermore, Figure 7 The flow characteristic curve of a quick-opening water valve is shown. From Figure 7It can be seen that for quick-opening water valves, the changes in the flow rate Q and the opening value L are not linearly related. In this case, if the valve opening value is adjusted proportionally, when the flow rate is low, the rate of change of the flow rate is greater than the rate of change of the valve opening value, resulting in excessive flow adjustment (i.e., too rapid flow adjustment). Conversely, when the flow rate is low, the rate of change of the flow rate is less than the rate of change of the valve opening value, resulting in insufficient flow adjustment (i.e., untimely flow adjustment).

[0130] Based on the above problems, in the water valve adjustment method proposed in this invention, based on the correspondence principle between functions and derivative functions, during the process of adjusting the opening of the water valve, the flow characteristic function of the water valve is differentiated to linearly correct the flow characteristic function of the water valve, thereby matching the target opening adjustment amount of the water valve with the target flow adjustment amount of the water valve, ensuring the accuracy of the water valve opening adjustment.

[0131] In other words, the water valve adjustment method proposed in this invention can achieve the following beneficial effects:

[0132] 1. Suitable for water coil air conditioners;

[0133] 2. It can linearly correct the flow characteristic function of the water valve, ensuring a high degree of matching between the target opening adjustment and the target flow adjustment of the water valve, thus reducing the limitations of water valve selection.

[0134] 3. When replacing water valves in subsequent maintenance, it is not necessary to specially match water valves with the same flow characteristic curve. It is only necessary to write the flow characteristic curve function of the new water valve into the program, and the water valve adjustment method in the above embodiment can be used to linearly correct the flow characteristic function of the water valve, thereby reducing maintenance costs.

[0135] Example 6, Figure 8 A structural block diagram of a water valve regulating device 800 according to an embodiment of the present invention is shown. Specifically, the regulating device may include a processing unit 802:

[0136] Processing unit 802 is used to determine a second mapping relationship between the opening adjustment value and the flow adjustment value of the water valve based on a first mapping relationship between the flow value and the opening value of the water valve.

[0137] The processing unit 802 is also used to determine the target opening adjustment value of the water valve based on the target flow adjustment value of the water valve, the current opening value, and the second mapping relationship;

[0138] The processing unit 802 is also used to adjust the opening of the water valve according to the target opening adjustment value.

[0139] The water valve regulating device 800 proposed in this invention includes a processing unit 802. In the process of regulating the opening value of the water valve, the processing unit 802 first determines a first mapping relationship between the opening value of the water valve and the flow rate value of the water valve. Then, the processing unit 802 determines a second mapping relationship between the flow rate regulation amount and the opening value regulation amount of the water valve based on the first mapping relationship. Then, the processing unit 802 determines the target opening value regulation amount of the water valve based on the determined second mapping relationship, the target flow rate regulation amount of the water valve, and the current opening value of the water valve, and adjusts the opening of the water valve according to the target opening value regulation amount.

[0140] It is understood that the second mapping relationship between the flow rate adjustment and the opening adjustment of the water valve can also be used to characterize the correspondence between the flow rate change rate and the opening rate change rate of the water valve. Based on this, in the water valve adjustment device 800 proposed in this invention, when the processing unit 802 adjusts the opening value of the water valve in conjunction with the above-mentioned second mapping relationship, it can correct the opening adjustment amount of the water valve by combining the correspondence between the flow rate change rate and the opening rate change rate of the water valve. This ensures a high degree of matching between the opening adjustment amount and the flow rate adjustment amount of the water valve, avoiding problems such as the opening adjustment amount being too small or too large, improving the accuracy of the water valve opening adjustment, and consequently improving the accuracy of the air conditioning supply temperature adjustment during subsequent air conditioning operation.

[0141] The first mapping relationship mentioned above can be determined based on the flow characteristic curve of the water valve, which is a curve characterizing the correspondence between the opening value and the flow rate value of the water valve. In practical applications, the flow characteristic curve can be pre-stored in the storage space of the water valve regulating device 800, and can be directly retrieved and used during the adjustment of the water valve opening. Alternatively, the flow characteristic curve can be obtained from the water valve specification diagram or through multiple experimental tests. Those skilled in the art can set it according to the actual situation, and no specific limitations are imposed here.

[0142] Furthermore, the aforementioned second mapping relationship can also be used to characterize the correspondence between the rate of change of flow rate and the rate of change of opening of the water valve. In practical applications, the aforementioned second mapping relationship can be specifically determined through the derivative function of the flow characteristic curve of the water valve. Based on this, combined with the current opening value of the water valve and the aforementioned second mapping relationship, the rate of change of the water valve opening at the current opening value can be determined. Then, the water valve opening adjustment amount can be corrected according to this rate of change, so that the water valve opening adjustment amount can match the flow rate adjustment amount, thereby ensuring the accuracy of the water valve opening adjustment.

[0143] Furthermore, in the process of adjusting the opening value of the water valve to regulate the air supply temperature of the air conditioning unit, the aforementioned target flow rate adjustment value is a known quantity, and this target flow rate adjustment value corresponds to the target air supply temperature of the air conditioning unit. Specifically, during the operation of the air conditioning unit, the current air supply temperature of the air conditioning unit and the target air supply temperature set by the user can be obtained, and then the temperature difference between the current air supply temperature and the target air supply temperature can be determined. Based on this temperature difference, the required target flow rate adjustment value is determined. On this basis, after adjusting the opening value of the water valve according to the determined target flow rate adjustment value, the air supply temperature of the air conditioning unit can be adjusted to the aforementioned target air supply temperature.

[0144] In summary, the water valve regulating device 800 proposed in this invention, through the processing unit 802, determines the second mapping relationship between the water valve's flow rate regulation and its opening rate regulation based on the first mapping relationship between the water valve's opening value and flow rate, as characterized by the water valve's flow characteristic curve. This means determining the correspondence between the water valve's flow rate change rate and its opening rate change rate. Based on this, the processing unit 802 further corrects the water valve's opening rate regulation by combining the correspondence between the flow rate change rate and the opening rate change rate, thereby ensuring a high degree of matching between the water valve's opening rate regulation and its flow rate regulation. This avoids problems such as excessively small or large opening rate regulation, improving the accuracy of water valve opening regulation and consequently enhancing the accuracy of air conditioning supply temperature regulation during subsequent air conditioning operation.

[0145] In Example 7, based on Example 6, the processing unit 802 is further configured to: determine the flow characteristic function of the water valve according to the first mapping relationship between the flow rate value and the opening value of the water valve; determine the target adjustment function according to the flow characteristic function; and determine the second mapping relationship between the opening adjustment value and the flow adjustment value of the water valve according to the target adjustment function.

[0146] In this embodiment, the specific method by which the processing unit 802 determines the second mapping relationship between the flow rate adjustment and the opening adjustment of the water valve based on the first mapping relationship between the opening value and the flow rate value is defined. Specifically, in the process of determining the second mapping function, the processing unit 802 first determines the flow characteristic function of the water valve based on the first mapping relationship. This flow characteristic function is a specific functional form of the flow characteristic curve of the water valve, which can express the correspondence between the opening value and the flow rate value of the water valve. Based on this, the processing unit 802 determines a target adjustment function according to the determined flow characteristic function. This target adjustment function can be used to characterize the correspondence between the flow rate change value and the opening change value of the water valve. Based on this, the processing unit 802 then determines the second mapping relationship between the flow rate adjustment and the opening adjustment of the water valve based on the correspondence between the flow rate change value and the opening change value of the water valve, that is, based on the target adjustment function.

[0147] In this way, during the process of adjusting the opening value of the water valve by the processing unit 802, the corresponding relationship between the change value of the water valve flow rate and the change value of the opening can be combined to correct the water valve opening adjustment value, thereby ensuring a high degree of matching between the water valve opening adjustment amount and the flow rate adjustment amount, avoiding the problem of the water valve opening adjustment amount being too small or too large, improving the accuracy of water valve opening adjustment, and thus improving the accuracy of air conditioning supply temperature adjustment in subsequent air conditioning operation.

[0148] The flow characteristic function of the aforementioned water valve describes the correspondence between the valve's opening value and its flow rate. Specifically, this flow characteristic function can be a functional equation with the valve opening value as the independent variable and the valve flow rate as the dependent variable. Furthermore, the aforementioned target adjustment function describes the correspondence between the change in the valve's flow rate and the change in its opening value. This target adjustment function can also be a functional equation with the change in flow rate as the independent variable and the change in opening value as the dependent variable. Based on this, and considering the principle and characteristics of the function, the processing unit 802 can obtain the aforementioned target adjustment function by differentiating the aforementioned flow characteristic function, thus ensuring the accuracy of the determination of the aforementioned second mapping relationship.

[0149] In Example 8, based on Example 7, the processing unit 802 is further specifically used to: determine the first derivative of the flow characteristic function with respect to the water valve flow rate, and the second derivative of the flow characteristic function with respect to the water valve opening degree; determine the target derivative function of the flow characteristic function based on the second derivative and the first derivative; determine the target adjustment function based on the target derivative function; and determine the second mapping relationship between the water valve opening adjustment value and the flow adjustment value based on the target adjustment function.

[0150] In this embodiment, the specific method by which the processing unit 802 determines the target adjustment function using the flow characteristic function of the water valve is defined. Specifically, during the process of determining the target adjustment function using the flow characteristic function of the water valve, the processing unit 802, based on the principle characteristics of the function, can determine the target adjustment function by differentiating the flow characteristic function, thereby ensuring the accuracy of the determination of the second mapping relationship.

[0151] Specifically, the above-mentioned flow characteristic function can be a functional equation with the water valve opening value as the independent variable and the water valve flow rate value as the dependent variable. In practical applications, the above-mentioned flow characteristic function can be expressed by the following formula (1):

[0152] Q=F(L) (1)

[0153] Where Q is the flow rate of the water valve, and L is the opening degree of the water valve.

[0154] Based on this, after determining the flow characteristic function of the water valve, the equations on both sides of the flow characteristic function equation can be differentiated simultaneously to obtain the target differential expression of the flow characteristic function. This target differential expression includes the first differential expression of the flow characteristic function relative to the water valve flow rate value, and the second differential expression of the flow characteristic function relative to the water valve opening value. In practical applications, the target differential expression can be specifically expressed by the following formula (2):

[0155] dQ=F'(L)dL (2)

[0156] Where dQ is the first differential of the flow characteristic function with respect to the flow rate Q of the water valve, F'(L)dL is the second differential of the flow characteristic function with respect to the opening value L of the water valve, F'(L) is the derivative of F(L) with respect to the opening value L of the water valve, and dL is the differential of the opening value L of the water valve.

[0157] Furthermore, during the adjustment of the water valve opening, the target flow rate adjustment value is known. Therefore, after determining the target differential equation, it can be transformed into a target derivative function with the differential dL of the opening value L as the dependent variable. That is, the equations on both sides of the equation are simultaneously divided by F'(L). In practical applications, the target derivative function can be specifically expressed by the following formula (3):

[0158] dL=dQ / F'(L) (3)

[0159] Where dL is the derivative of the valve opening value L, dQ is the derivative of the valve flow rate value Q, and F'(L) is the derivative of F(L) with respect to the valve opening value L.

[0160] It is understandable that in the above objective derivative function, dL is the differential of the water valve opening value L, which can characterize the change of the water valve opening value in an infinitely small time interval, that is, the rate of change of the water valve opening value; dQ is the differential of the water valve flow rate value Q, which can characterize the change of the water valve flow rate value in an infinitely small time interval, that is, the rate of change of the water valve flow rate value.

[0161] Based on this, the derivative dL of the water valve opening value L in the above target derivative function can be used as the opening adjustment value, and the derivative dQ of the water valve flow rate value Q can be used as the flow rate adjustment value. Thus, the target derivative function is transformed into a target adjustment function that characterizes the correspondence between the water valve opening adjustment value and the flow rate adjustment value. In practical applications, the above target adjustment function can be specifically expressed by the following formula (4):

[0162] △L=△Q / F'(L) (4)

[0163] Where △L is the opening adjustment value of the water valve, △Q is the flow adjustment value of the water valve, and F'(L) is the derivative of the flow characteristic function F(L) of the water valve with respect to the opening value L of the water valve.

[0164] In Example 9, based on Example 8, the processing unit 802 is further used to: substitute the target flow rate adjustment value and the current opening value of the water valve into the target adjustment function to obtain the target opening adjustment value.

[0165] In this embodiment, the specific method by which the processing unit 802 determines the target opening adjustment value of the water valve using the second mapping relationship, the current opening value of the water valve, and the target flow adjustment value is defined. Specifically, the target adjustment function corresponds to the second mapping relationship and can be used to characterize the correspondence between the opening adjustment value and the flow adjustment value of the water valve, that is, to characterize the second mapping relationship. Based on this, in this technical solution, the processing unit 802 can also obtain the current opening value and the target flow adjustment value of the water valve, and after determining the target adjustment function corresponding to the second mapping relationship, substitute the obtained current opening value and target flow adjustment value of the water valve into the target adjustment function to obtain the target opening adjustment value of the water valve.

[0166] It is understandable that the aforementioned target adjustment function is related to the valve opening adjustment value, the valve flow adjustment value, and the derivative of the valve flow characteristic function with respect to the valve opening value. Specifically, the derivative of the valve flow characteristic function with respect to the valve opening value can be used to characterize the rate of change of the valve flow rate relative to the valve opening value, that is, to characterize the rate of change of the valve flow adjustment value relative to the valve opening adjustment value. Based on this, the obtained current valve opening value and target flow adjustment value are substituted into the aforementioned target adjustment function to determine the target valve opening adjustment value. This allows for correction of the valve opening adjustment value by considering the rate of change of the valve flow adjustment value relative to the valve opening adjustment value at the current opening value, thereby ensuring the accuracy of determining the target valve opening adjustment value and ensuring the accuracy of air conditioning supply temperature regulation during subsequent air conditioning operation.

[0167] For example, when the current opening value of the water valve is L1, and the target flow rate adjustment value is △Q1 determined based on the current supply air temperature and the target supply air temperature of the air conditioning equipment, the target opening adjustment value △L1 of the water valve can be expressed by the following formula (5):

[0168] △L1=△Q1 / F'(L1) (5)

[0169] Where △L1 is the target opening adjustment value of the water valve, L1 is the current opening value of the water valve, △Q1 is the target flow adjustment value of the water valve, and F'(L1) is the derivative of the flow characteristic function of the water valve with respect to the opening value of the water valve at the current opening value.

[0170] In Example 10, based on Examples 6 to 9, the processing unit 802 is further used to: determine the target opening value of the water valve according to the target opening adjustment value and the current opening value; and adjust the opening of the water valve to the target opening value.

[0171] In this embodiment, the specific method by which the processing unit 802 adjusts the opening of the water valve using the target opening adjustment value is defined. Specifically, after the processing unit 802 determines the target opening adjustment value of the water valve, it increases or decreases the target opening adjustment value based on the current opening value of the water valve to obtain the target opening value of the water valve, which corresponds to the target air supply temperature of the air conditioning equipment. Based on this, by adjusting the opening value of the water valve from the current opening value to the target opening value through the processing unit 802, the air supply temperature of the air conditioning equipment can be adjusted to the target air supply temperature to meet the user's air supply needs.

[0172] The target opening adjustment value is obtained by correcting the water valve's opening adjustment value based on the rate of change of the water valve's flow rate adjustment value relative to its opening adjustment value at the current opening value. Therefore, when the processing unit 802 adjusts the water valve's opening value using the target opening adjustment value, the accuracy of determining the target opening value is ensured, thereby guaranteeing a high degree of matching between the target opening value and the target supply air temperature. This, in turn, ensures the accuracy of the air conditioning supply air temperature adjustment during subsequent air conditioning operation.
