[0056] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0057] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0058] The main solution of the embodiment of the present application is: obtaining the initial water supply temperature of the hydraulic module; controlling the operation of the hydraulic module based on the initial water supply temperature of the hydraulic module, and collecting operating data during the operation of the hydraulic module; determining the target water supply temperature correction value through the operating data; correcting the initial water supply temperature of the hydraulic module through the target water supply temperature correction value to control the water supply temperature of the hydraulic module.

[0059] The first type of prior art is to obtain the user's room temperature requirements by indirectly setting the water supply temperature; the user's room temperature requirements are relatively clear, but the water supply temperature requirements are not very clear, so the set temperature value can only be repeatedly corrected by the room temperature comfort brought by the set water supply temperature. This solution brings difficulty to the user's operation and affects the user experience; the second is to automatically fit the corresponding water supply temperature according to the climate temperature collected by the outdoor unit. This temperature is out of the room temperature control required by the user, and the room temperature reached after the water supply temperature is heated may deviate from the room temperature required by the user. This solution simplifies the user's operation, but there is a deviation from the room temperature required by the user, which affects the user experience; the third is to obtain the room demand temperature and current room temperature of each room through the room duct machine, and then calculate the water supply temperature in combination with the heat transfer temperature difference of the unit. This solution is easy for users to operate, but in some application scenarios, the room temperature provided by the calculated water supply temperature may deviate greatly from the user's requirements or the calculated water supply temperature is too high, causing the unit to start and stop frequently, which has a certain impact on the user experience.

[0060] The present application provides a solution, which is based on a control method for calculating the water supply temperature based on the room demand temperature and the heat transfer temperature difference set by the unit, and then making corrections based on the actual room temperature changes to achieve the effect of accurately meeting the room demand temperature and efficient operation of the unit.

[0061] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a controller of a water supply module in an air conditioner, etc. The controller of a water supply module in an air conditioner is taken as an example to illustrate this embodiment and the following embodiments.

[0062] Based on this, the present application embodiment provides a water supply temperature control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the water supply temperature control method of the present application.

[0063] In this embodiment, the water supply temperature control method is applied to an air conditioner, which includes an indoor unit and an outdoor unit. The indoor unit includes a duct unit and a hydraulic module. The duct unit, the hydraulic module and the outdoor unit are interconnected.

[0064] In this embodiment, the water supply temperature control method includes steps S10 to S40:

[0065] Step S10: Obtaining the initial water supply temperature of the hydraulic module.

[0066] like Figure 2 As shown, Figure 2It is a structural diagram of an air conditioner, which mainly includes an outdoor unit 10 and an indoor unit 20. The indoor unit 20 includes a hydraulic module 201, multiple air duct units 202 and piping components connecting various parts. The air conditioner is a natural fluorine and ground water system, wherein the air duct units 202 for fluorine circulation are generally installed on the indoor roof (i.e. natural fluorine), and the number of air duct units 202 is set to multiple. The heating hydraulic module 201 converts the heat of the fluorine system circulated from the outdoor unit into water to supply hot water to users so as to heat the indoor floor heating, radiators or dryers in the bathroom and other water system terminals (ground water). Therefore, this system is called a natural fluorine and ground water system as the name suggests. The outdoor unit 10 mainly includes: compressor 101, pressure sensor 102, four-way reversing valve 103, fin heat exchanger 104, fan (not shown in the figure), electronic expansion valve 105, stop valve 106, gas-liquid separator and other parts required by the system (not shown in the figure); the hydraulic module 201 mainly includes: water-fluorine heat exchanger (including but not limited to plate heat exchanger, sleeve heat exchanger, shell and tube heat exchanger), electronic expansion valve and water flow switch and other water accessories; the duct unit 202 mainly includes: fin heat exchanger, fan, electronic expansion valve and other parts required by the system. This method is to control the duct unit 202 and the hydraulic module 201 in linkage, automatically calculate the water supply temperature of the hydraulic module 201 according to the required indoor ambient temperature, and then control the operation of the hydraulic module 201.

[0067] It should be noted that the initial water supply temperature of the hydraulic module is the temperature when the hydraulic module starts to run. The water supply temperature of the hydraulic module is calculated based on the set temperature of all rooms with floor heating needs, the heat transfer temperature difference of floor heating in the room, and the water supply temperature correction value of the hydraulic module. The water supply temperature correction value is initially set to 0℃ by default.

[0068] In a feasible implementation, step S10 may include steps A11 to A12:

[0069] Step A11: respond to the heating demand of the hydraulic module and determine the set temperature of the required room according to the heating demand.

[0070] It should be noted that the hydraulic module heating demand is the user's floor heating demand. When the room thermostat is turned on, the user selects hydraulic module heating and sets the required room set temperature. Therefore, when the user turns on the hydraulic module heating, the hydraulic module heating demand is generated, and the required room set temperature can be received at this time.

[0071] The demand room set temperature is the indoor set temperature of all rooms with heating demand set by the user.

[0072] Step A12: Determine the initial water supply temperature of the hydraulic module based on the required room set temperature.

[0073] In a specific implementation, the initial water supply temperature of the hydraulic module can be determined based on the required room set temperature. The initial water supply temperature of the hydraulic module can be calculated by the weighted average of the required room set temperature. Therefore, step A12 may include: obtaining the room floor heating heat transfer temperature difference, the theoretical heating capacity of the unit, and the theoretical total heating capacity of the unit in the required room; determining the first weighted average temperature of the required room set temperature according to the required room set temperature, the theoretical heating capacity of the unit, and the theoretical total heating capacity of the unit in the required room; determining the initial water supply temperature of the hydraulic module by the first weighted average temperature and the room floor heating heat transfer temperature difference.

[0074] It should be noted that the heat transfer temperature difference △T of floor heating in the room is the difference between the water supply temperature and the stable room temperature obtained by floor heating. It is set according to the floor heating design regulations. The default is an initial value. Users can also modify it according to their own room conditions, such as 2°C, 3°C, etc.

[0075] In specific implementation, the theoretical heating capacity of the unit is the nominal heating capacity of the unit, and the total theoretical heating capacity of the demand room unit is the sum of the nominal heating capacity of all the rooms with floor heating demand. The first weighted average temperature T of the required room set temperature 室设 It is the ratio of the sum of the product of the set temperature of the demand room and the nominal heating capacity of the unit to the total theoretical heating capacity of the demand room unit.

[0076] The water supply temperature of the hydraulic module is calculated as follows:

[0077] TW 设 =T 室设 +△T+dTW

[0078] Among them, TW 设 is the water supply temperature setting value of the hydraulic module, T 室设 is the first weighted average temperature of the required room set temperature, △T is the room floor heating heat transfer temperature difference, dTW is the water supply temperature correction value of the hydraulic module, which is initially 0℃, so the initial water supply temperature of the hydraulic module = T 室设 +△T.

[0079] Users only need to set the required room temperature to control the hydraulic module of the floor heating. There is no need to repeatedly set the water temperature to obtain the appropriate room temperature, making the unit more convenient to use.

[0080] Step S20: Controlling the operation of the hydraulic module based on the initial water supply temperature of the hydraulic module, and collecting operation data of the hydraulic module during operation.

[0081] It should be noted that after calculating the initial water supply temperature of the hydraulic module, the hydraulic module can be controlled by this temperature to start the heating operation. After the hydraulic module starts to operate, there will be a certain temperature difference between the room demand temperature and the actual room temperature. Therefore, it is necessary to continuously perform temperature correction in combination with the room demand temperature and the actual room temperature, so as to adjust the value of the initial water supply temperature of the hydraulic module and improve the comfort of room heating. Therefore, the operation data of the hydraulic module during operation can be collected. The operation data may include data such as the continuous operation time of the hydraulic module startup operation, the current room temperature value, and other data, which are not limited in this embodiment.

[0082] Step S30: Determine the target water supply temperature correction value through the operation data.

[0083] In a specific implementation, the target water supply temperature correction value is an increase or decrease value calculated based on the operation data. The initial water supply temperature correction value is 0°C. During the subsequent operation of the hydraulic module, the updated initial water supply temperature correction value can be continuously calculated to obtain the target water supply temperature correction value. For example, the target water supply temperature correction value is determined to be 3, -2, etc. based on the operation data.

[0084] Step S40: Correcting the initial water supply temperature of the hydraulic module by the target water supply temperature correction value to control the water supply temperature of the hydraulic module.

[0085] In a specific implementation, the initial water supply temperature of the hydraulic module can be corrected by the target water supply temperature correction value, that is, the target water supply temperature of the hydraulic module is calculated by the target water supply temperature correction value and the initial water supply temperature of the hydraulic module, and the target water supply temperature of the hydraulic module = the initial water supply temperature of the hydraulic module + the target water supply temperature correction value dTW, thereby controlling the operation of the hydraulic module by the target water supply temperature of the hydraulic module.

[0086] This embodiment provides a water supply temperature control method, which can set the room demand temperature under different usage requirements and different operating conditions. The hydraulic module can automatically correct and calculate the water supply target temperature, thereby maintaining the room temperature within the target room temperature range and improving the control effect of the water supply temperature.

[0087] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , step S30 includes steps S301 to S302:

[0088] Step S301: Obtain the continuous operation time of the hydraulic module and the current room temperature through the operation data.

[0089] It should be noted that the current room temperature is the current room temperature of each room of all rooms with heating demand, which can be measured by the temperature sensor in each room, and the continuous operation time of the hydraulic module is the time from when the hydraulic module is turned on to the present.

[0090] Step S302: Determine the target water supply temperature correction value according to the required room set temperature, the continuous operation time of the hydraulic module and the current room temperature.

[0091] In a specific implementation, the weighted average of the required room set temperature can be calculated through the required room set temperature, and then the corresponding target water supply temperature correction value can be determined through the weighted average, the continuous operation time of the hydraulic module and the current room temperature. When the continuous operation time of the hydraulic module is different, the corresponding target water supply temperature correction value is different, and when the current room temperature is different, the corresponding target water supply temperature correction value is also different.

[0092] In a feasible implementation, step S302 may include steps B11 to B14:

[0093] Step B11: Determine a first weighted average temperature of the required room setting temperature according to the required room setting temperature.

[0094] It should be noted that the first weighted average temperature of the required room setting temperature can be calculated by the required room setting temperature, and the calculation method is as described above.

[0095] Step B12: Calculate a second weighted average temperature of the current room temperature according to the current room temperature.

[0096] In a specific implementation, the second weighted average temperature of the current room temperature is a weighted average of the current room temperatures of all rooms.

[0097] Step B13: Calculate the temperature difference value by using the first weighted average temperature and the second weighted average temperature.

[0098] In a specific implementation, the temperature difference ΔTs may be calculated by the first weighted average temperature and the second weighted average temperature.

[0099] Step B14: Determine a target water supply temperature correction value based on the temperature difference value and the continuous operation time of the hydraulic module.

[0100] It is understandable that there is a corresponding relationship between the temperature difference value, the continuous operation time of the hydraulic module and the water supply temperature correction value. The corresponding relationship between the temperature difference value, the continuous operation time of the hydraulic module and the water supply temperature correction value can be established in advance, so that the target water supply temperature correction value can be determined according to the temperature difference value and the continuous operation time of the hydraulic module. When the temperature difference value and the continuous operation time of the hydraulic module are different, the corresponding water supply temperature correction value is different. Multiple judgment values ​​and multiple operation time thresholds can be set in advance to determine the specific water supply temperature correction value.

[0101] By using the weighted average value of the demand room values, the reliability of the unit operation can be guaranteed, and the fluctuation of temperature in small demand rooms and slow satisfaction of demand in large demand rooms can be avoided. It better meets the comfort requirements of different rooms in the same system and has better zoning control.

[0102] In a feasible implementation, step B14 may include:

[0103] Step B141: When the continuous operation time of the hydraulic module reaches a first preset time, determine whether the temperature difference value is greater than a first set temperature difference value.

[0104] In the specific implementation, the first preset time is Time1, which can be set to 5 minutes, 3 minutes, etc. This embodiment does not limit this. For example, Time1 is set to 5 minutes. When the hydraulic module continues to run for 5 minutes, it can be determined whether the temperature difference △Ts is greater than the first set temperature difference. The first set temperature difference T1 can be set to 5°C.

[0105] Step B142: When the temperature difference is greater than the first set temperature difference, a first correction value is determined, and the target water supply temperature correction value is determined by the first correction value.

[0106] It should be noted that if the temperature difference △Ts is greater than the first set temperature difference T1, the first correction value a can be determined, and a is a constant value, which can be set to 3°C or other values, and this embodiment does not limit this. The target water supply temperature correction value is the current water supply temperature correction value + a, and the current water supply temperature correction value is 0 at the initial time. During the subsequent operation of the hydraulic module, the water supply temperature correction value at the previous moment can be obtained as the current water supply temperature correction value.

[0107] Step B143: When the temperature difference value is less than or equal to the first set temperature difference value, determine whether the temperature difference value is greater than the second set temperature difference value.

[0108] It should be noted that if the temperature difference △Ts is less than or equal to the first set temperature difference T1, it can be further determined whether the temperature difference is greater than the second set temperature difference. The second set temperature difference is theoretically smaller than the first set temperature difference. The second set temperature difference T2 can be set to 4°C.

[0109] Step B144: When the temperature difference is greater than the second set temperature difference, a second correction value is determined, and the target water supply temperature correction value is determined by the second correction value.

[0110] In a specific implementation, if the temperature difference △Ts is greater than the second set temperature difference T2, the second correction value b is determined. b is a constant value and can be set to 2°C, 1°C, etc. It can also be set to other values. This embodiment does not limit this. The target water supply temperature correction value is the current water supply temperature correction value + b.

[0111] Step B145: When the temperature difference is less than or equal to the second set temperature difference, a third correction value is determined, and the target water supply temperature correction value is determined by the third correction value.

[0112] It should be noted that if the temperature difference △Ts is less than or equal to the second set temperature difference T2, the third correction value is determined to be c, where c is a constant value and can be set to 1°C or other values, which are not limited in this embodiment. The target water supply temperature correction value is the current water supply temperature correction value + c.

[0113] In a feasible implementation manner, step B14 may further include:

[0114] Step B141': when the continuous operation time of the hydraulic module reaches the second preset time, determine whether the temperature difference value is less than the third set temperature difference value.

[0115] It should be noted that the second preset time Time2 can be set to 2 minutes, 3 minutes, etc. The second preset time can be the same as or different from the first preset time, and this embodiment does not limit this.

[0116] When the continuous operation time of the hydraulic module reaches the second preset time Time2, it can be determined whether the temperature difference is less than the third set temperature difference T3. For example, T3 can be set to 3°C.

[0117] Step B142': when the temperature difference is less than the third set temperature difference, determine the fourth correction value, and determine the target water supply temperature correction value according to the fourth correction value.

[0118] In a specific implementation, if the temperature difference ΔTs is less than the third set temperature difference T3, the correction value is determined to be the fourth correction value d, and d can be set to -2°C or other values, which is not limited in this embodiment.

[0119] Target water supply temperature correction value = current water supply temperature correction value + d.

[0120] Step B143': when the temperature difference is greater than or equal to the third set temperature difference, determine the third correction value, and determine the target water supply temperature correction value according to the third correction value.

[0121] In a specific implementation, when the temperature difference ΔTs is greater than or equal to the third set temperature difference T3, the correction value is determined to be the third correction value c, and the target water supply temperature correction value is determined by the third correction value, and the target water supply temperature correction value = the current water supply temperature correction value + c.

[0122] In a specific implementation, after the target water supply temperature correction value is determined by correcting with any one of the first correction value, the second correction value, the third correction value or the fourth correction value, the hydraulic module can be controlled to operate at the water supply temperature corresponding to the target water supply temperature correction value for a period of time, for example, continuously operating for Time3, Time3 can be the same as or different from Time1, and the step of returning again to determine the relationship between the temperature difference value and the first set temperature difference value and the second set temperature difference value, so as to determine the first correction value, the second correction value or the third correction value, repeats the correction of the water supply temperature correction value, and obtains the operating time of the hydraulic module after the correction, and when the operating time reaches Time4, returns again to determine the relationship between the temperature difference value and the third set temperature difference value, so as to determine the third correction value or the fourth correction value, repeats the correction of the water supply temperature correction value, and the subsequent correction can directly repeat the above-mentioned comparison step after the operating time reaches Time3 or Time4, so as to repeat the correction.

[0123] This embodiment obtains the continuous operation time of the hydraulic module and the current room temperature through operating data; determines the target water supply temperature correction value according to the required room set temperature, the continuous operation time of the hydraulic module and the current room temperature, and automatically corrects the water supply temperature according to the rate of change of the difference between the current room temperature and the target temperature. When the unit is properly selected, the heating comfort is less affected by factors such as the outdoor temperature, so that the room temperature is always maintained within the target temperature range, and the unit is more comfortable to use, thereby accurately meeting the required room temperature and the efficient operation of the unit.

[0124] For example, in order to help understand the implementation process of the water supply temperature control method obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 4 , Figure 4A brief flow chart of a water supply temperature control method is provided, specifically: ① when the hydraulic module is turned on, the initial water supply temperature correction value dTW=0, ② when the hydraulic module continues to run for Time1, it is judged whether the temperature difference value △Ts is greater than the first set temperature difference value T1, if so, the target water supply temperature correction value = dTW (which can be the current water supply temperature correction value or 0) + a℃, if not, it is judged whether △Ts is greater than the second set temperature difference value T2, if so, the target water supply temperature correction value = dTW (which can be the current water supply temperature correction value or 0) + b℃, if not, the target water supply temperature correction value = dTW (which can be the current water supply temperature correction value or 0) + b℃, if Temperature correction value = dTW (can be the current water supply temperature correction value or 0) + c℃; ③ When the hydraulic module continues to run for Time2 time, determine whether the temperature difference △Ts is less than the third set temperature difference T3. If so, the target water supply temperature correction value is based on the current value + d℃, if not, the target water supply temperature correction value = dTW (can be the current water supply temperature correction value or 0) + c℃; ④ After ② and ③ corrections, repeat ② correction when it continues to run for Time3 time, and repeat ③ correction when it continues for Time4 time after ② and ③ corrections; ⑤ Repeat ④ for subsequent corrections. The required temperature of the floor heating room can be set under different usage requirements and different operating conditions, and the hydraulic module can automatically correct and calculate the target water supply temperature, so as to maintain the room temperature within the target room temperature range; this method can effectively simplify user operations and reduce the user's troubles of not knowing how to set the water temperature, while achieving the comfort and reliability of zoned temperature control.
