[0064] In some cases, water is commonly used as a heat storage and transmission medium in radiant air conditioning, and the room temperature environment is adjusted by controlling the water temperature in the pipes laid in the room. For the control of the pipe water temperature, a mixing water control unit is usually introduced, with the set mixing water temperature as the target, and the heat distribution of each water circuit is calculated by analyzing the temperature and flow rate of the inlet water, return water and mixing water, so as to control the opening degree of the mixing water ratio valve and output relatively constant mixed water into the indoor water circuit coil.

[0065] Although a complete mixing water control unit can be formed by controlling the opening degree of the proportional valve based on the target mixing water temperature according to the inlet water, return water, mixing water temperature and flow rate, the current mixing water method lacks consideration of the influence of the room environment factors that the pipeline passes through. Especially in the case of multi-room temperature control, it will significantly affect the timeliness and comfort of temperature control in each room, is not conducive to energy conservation, and may also cause the risk of room condensation in special environments.

[0066] Based on the above situation, the embodiments of the present application propose a mixing water control method, a controller, a mixing water device, a heat pump water system and a medium, aiming to improve the comfort of room temperature control and reduce the occurrence of condensation.

[0067] The following further elaborates on each embodiment of the mixing water device and the heat pump water system of the present application in conjunction with the accompanying drawings.

[0068] As Figure 1 shown, Figure 1 is a schematic diagram of the structural connection relationship of a mixing water device provided by an embodiment of the present application.

[0069] In one embodiment, the mixing water device 110 of the embodiment of the present application is provided with an inlet water channel A, a return water channel B and an outlet water channel C. The inlet water channel A is used to communicate with the water supply port of the heat pump device, the outlet water channel C is used to communicate with the water inlet of the indoor heat exchange device 300, and the return water channel B is used to communicate with the water outlet of the indoor heat exchange device 300 and the return water port of the heat pump device.

[0070] Specifically, the water supply port of the heat pump device is connected with a water supply pipeline, and this water supply pipeline is connected to the water inlet of the indoor heat exchange device 300 through the inlet water channel A and the outlet water channel C of the mixing water device 110. In addition, the water outlet of the indoor heat exchange device 300 is connected with a return water pipeline, and this return water pipeline is connected to the return water port of the heat pump device and is also connected to the return water channel B of the mixing water device 110. This return water channel B can be connected to the outlet water channel C, so that the returned water can flow from the mixing water device 110 back to the water inlet of the indoor heat exchange device 300.

[0071] It should be noted that in one embodiment, when the opening degree of the mixing water device 110 is in the fully closed state, that is, when the outlet water channel C is closed and the water in the inlet water channel A all flows to the return water channel B, the mixing water device 110 is in the bypass state; in addition, when the opening degree of the mixing water device 110 is in the fully open state, that is, when the return water channel B is closed and the water in the inlet water channel A all flows to the inlet water channel A, the mixing water device 110 is in the direct-through state; in addition, when the opening degree of the mixing water device 110 is between fully open and fully closed, that is, when the water in the inlet water channel A and the return water channel B both flow to the inlet water channel A, the mixing water device 110 is in the mixing water state.

[0072] Since the mixing device 110 of the embodiment of the present application can perform mixing treatment on the supply water and the return water, and since the supply water temperature and the return water temperature are inconsistent, the mixing device 110 will obtain a mixed water temperature after the mixing treatment and supply the water with the mixed water temperature to the indoor heat exchange device 300.

[0073] In addition, it is worth noting that the mixing device 110 of the embodiment of the present application may be Figure 1 the three-way proportional valve shown in Figure 1 or a combined structure of multiple two-way valves. For example, the mixing device 110 of the embodiment of the present application may include three two-way valves, where the three two-way valves can be respectively installed at the pipeline at the three positions of the water inlet channel A, the return water channel B, and the water outlet channel C shown in

[0074] In one embodiment, as shown in Figure 1 the mixing device 110 of the embodiment of the present application further includes but is not limited to a mixing controller 130 and an actuator 120. Among them, the mixing controller 130 and the actuator 120 are communicatively connected, and the mixing controller 130 can control the valve opening of the mixing device 110 through the actuator 120.

[0075] In one embodiment, as shown in Figure 1 the mixing device 110 of the embodiment of the present application further includes but is not limited to a control host 200. Among them, the control host 200 and the mixing controller 130 are communicatively connected.

[0076] In one embodiment, as shown in Figure 1 the mixing device 110 of the embodiment of the present application further includes but is not limited to a mixed water temperature sensor 400. Among them, the mixed water temperature sensor 400 is arranged on the pipeline between the water outlet channel C and the water inlet of the indoor heat exchange device 300 and is communicatively connected to the mixing controller 130.

[0077] In one embodiment, the heat pump water system of the embodiment of the present application includes a heat pump device, an indoor heat exchange device 300, and the mixing device 110 of the above embodiment.

[0078] It should be noted that, in one embodiment, the heat pump device includes but is not limited to a water-fluorine heat exchanger, a supply water pump, and a heat pump pipeline. The water-fluorine heat exchanger and the supply water pump are both arranged on the heat pump pipeline. One end of the heat pump pipeline is the above-mentioned supply water port, and the other end is the above-mentioned return water port.

[0079] Specifically, in one embodiment, the heat pump device further includes a first heat exchange coil and a compressor. Additionally, the water-fluorine heat exchanger includes, but is not limited to, a second heat exchange coil and a third heat exchange coil. The first heat exchange coil, the compressor, and the second heat exchange coil together form a circulation loop using fluorine as the refrigerant; the third heat exchange coil is connected to the heat pump pipeline and together with the water supply pipeline, the indoor heat exchange device 300, and the water return pipeline forms another circulation loop using water as the refrigerant. Among them, the second heat exchange coil and the third heat exchange coil are not connected, and heat exchange can occur between the second heat exchange coil and the third heat exchange coil.

[0080] It should be noted that, in one embodiment, regarding the installation position of the above-mentioned indoor heat exchange device 300, the indoor heat exchange device 300 can be installed at the floor position of the room, or can be installed at the ceiling position of the room, or the installation position of the indoor heat exchange device 300 can be reasonably allocated according to actual usage needs. The embodiments of the present application do not make specific limitations on this.

[0081] In addition, it should be noted that, regarding the device type of the above-mentioned indoor heat exchange device 300, it can be an air handling unit end formed by cooperating with a fan coil, or can be a radiant end formed by cooperating with a radiant panel, or can be other types of radiant ends. The embodiments of the present application do not make specific limitations on the device type of the above-mentioned indoor heat exchange device 300.

[0082] In one embodiment, as Figure 1 shown, the heat pump water system of the embodiments of the present application further includes, but is not limited to, a circulation pump 500. Among them, the circulation pump 500 is arranged on the pipeline between the water outlet channel C and the water inlet of the indoor heat exchange device 300.

[0083] In one embodiment, as Figure 1 shown, the heat pump water system of the embodiments of the present application further includes, but is not limited to, a stop valve 620. Among them, the stop valve 620 is arranged on the pipeline between the water supply port of the heat pump device and the water inlet channel A, and is also arranged on the pipeline between the water return port of the heat pump device and the water outlet of the indoor heat exchange device 300.

[0084] In one embodiment, as Figure 1 shown, the heat pump water system of the embodiments of the present application further includes, but is not limited to, a check valve 610. Among them, the check valve 610 is arranged on the pipeline on the side of the water return channel B.

[0085] Specifically, for Figure 1The structure shown is the electrical schematic diagram of the mixing water control unit in a single room or a certain room in a multi-room system. Among them, the control host 200 is a local or remote controller that receives the energy demand set by the user and transmits instructions or parameters such as the target mixing water temperature Tws, room temperature Tr, room condensation temperature Tdew, and room surface condensation temperature Tsur to the mixing water controller 130, indirectly controlling the room environment. The mixing water controller 130 directly controls the actuator 120, the mixing water temperature sensor 400, and the circulation water pump 500. The mixing water device 110 is a three-way flow proportional control three-way valve that provides steering power through the actuator 120 to adjust the return water ratio between the front-end water inlet side A and the return water side B, and outputs the mixed water flow from the C side of the proportional three-way valve. The actuator 120 is controlled by the mixing water controller 130 to provide steering power for the three-way valve. The mixing water temperature sensor 400 detects the water temperature of the C side after mixing water through the proportional three-way valve and feeds it back to the mixing water controller 130. The circulation water pump 500 is controlled by the mixing water controller 130 to provide power for the water flow loop. The coiled pipe in the indoor heat exchanger is the carrier of the heat radiation source, and the water flow is unidirectional, entering from the water inlet of the indoor heat exchanger and exiting from the water outlet of the indoor heat exchanger. In addition, the check valve 610 is a one-way conduction valve, which functions to prevent the water flow from flowing back to the return water port of the heat pump device or the water outlet of the indoor heat exchanger due to unstable water pressure or other factors. In addition, the stop valve 620 is a two-way flow valve that has only a fully open or fully closed state. It is installed in the water supply pipeline and the return water pipeline and plays a role in isolating from the terminal water use pipeline when repairing either side of the pipeline or in special states. During normal operation, these two stop valves 620 are fully open.

[0086] Based on the hardware structure of the mixing water device in the above various embodiments, the following are the various embodiments of the mixing water control method of the present application.

[0087] As Figure 2 shown, Figure 2 is the flowchart of the mixing water control method provided by an embodiment of the present application; this control method can be applied to the mixing water device in the above embodiment, including but not limited to step S210, step S220, and step S230.

[0088] Step S210: Obtain the room temperature and the condensation temperature;

[0089] Step S220: Determine the current condensation risk parameter according to the room temperature and the condensation temperature;

[0090] Step S230: When the current condensation risk parameter is less than the preset condensation risk parameter, control the valve opening of the mixing water device according to the current condensation risk parameter to adjust the water inlet flow rate of the water inlet channel and / or the water return flow rate of the water return channel.

[0091] In one embodiment, first, the embodiment of the present application obtains the room temperature and the condensation temperature; then, the room temperature and the condensation temperature are compared and calculated to obtain the current condensation risk parameter; next, the embodiment of the present application compares the current condensation risk parameter with the preset condensation risk parameter. If the current condensation risk parameter is less than the preset condensation risk parameter, it indicates that there is a current condensation risk. At this time, the embodiment of the present application adjusts the valve opening of the mixing water device based on the magnitude of the current condensation risk parameter, thereby adjusting the ratio of the inlet water flow rate and the return water flow rate, and further being able to adjust the mixing water temperature and reduce the occurrence of condensation.

[0092] It can be understood that for the above-mentioned method of obtaining the room temperature, it can be detected by a temperature sensor set indoors, or obtained by user input, or obtained by other means. The embodiment of the present application does not specifically limit the method of obtaining the room temperature.

[0093] In addition, it can be understood that regarding the above-mentioned method of obtaining the condensation temperature, it can be calculated based on the object temperature and humidity. The embodiment of the present application does not specifically limit the method of obtaining the condensation temperature.

[0094] In addition, it can be understood that regarding the above-mentioned preset condensation risk parameter, it can be preset, and it can be obtained through experiments or be an empirical value. The embodiment of the present application does not specifically limit the magnitude of the preset condensation risk parameter.

[0095] It should be noted that the control of the valve opening of the mixing water device includes, but is not limited to, the following situations: First, adjusting the valve opening of the mixing water device to separately adjust the inlet water flow rate of the inlet water channel. Adjusting the magnitude of the inlet water flow rate while the return water flow rate remains unchanged can achieve the adjustment of the mixing water temperature; Second, adjusting the valve opening of the mixing water device to separately adjust the return water flow rate of the return water channel. Adjusting the magnitude of the return water flow rate while the inlet water flow rate remains unchanged can achieve the adjustment of the mixing water temperature; Third, adjusting the valve opening of the mixing water device to simultaneously adjust the inlet water flow rate of the inlet water channel and the return water flow rate of the return water channel. Adjusting the mixing ratio of the inlet water flow rate and the return water flow rate can achieve the adjustment of the mixing water temperature.

[0096] In one embodiment, the ratio of the water inlet flow rate of the water inlet channel to the water return flow rate of the water return channel is positively correlated with the valve opening of the mixing device. Specifically, in the mixing state, when the valve opening of the mixing device is larger, the ratio of the water inlet flow rate to the water return flow rate is larger, and at this time, the mixing temperature will become higher and higher. When the valve opening of the mixing device is smaller, the ratio of the water inlet flow rate to the water return flow rate is smaller, and at this time, the mixing temperature will become lower and lower. In addition, in the fully closed state, that is, when the valve opening of the mixing device is 0%, at this time, the water outlet channel is closed and all the water in the water inlet channel flows to the water return channel, and the mixing device is in the bypass state. In addition, in the fully open state, that is, when the valve opening of the mixing device is 100%, at this time, the water return channel is closed and all the water in the water inlet channel flows to the water inlet channel, and the mixing device is in the direct-through state.

[0097] It should be noted that since the embodiment of the present application can obtain the current condensation risk according to the room temperature and the condensation temperature, and when the current condensation risk is relatively large, the embodiment of the present application will adjust the valve opening of the mixing device, and change the mixing temperature by changing the water inlet flow rate or the water return flow rate, so as to reduce the occurrence of condensation and improve the comfort of room temperature control.

[0098] It should be noted that regarding the determination of the current condensation risk parameter according to the room temperature and the condensation temperature in step S220 above, it may include but is not limited to Figure 3 or Figure 4 two implementation cases as follows:

[0099] As Figure 3 shown, Figure 3 is a flowchart of a mixing control method provided by another embodiment of the present application; regarding step S220 above, it may include but is not limited to step S310 and step S320.

[0100] Step S310, determine that the condensation temperature includes the room condensation temperature;

[0101] Step S320, determine the current room condensation risk parameter according to the room temperature, the room condensation temperature and the preset return difference temperature.

[0102] In one embodiment, when the condensation temperature is the room condensation temperature, for example, when the condensation temperature is the condensation temperature of the air in the room, the embodiment of the present application can calculate the current room condensation risk parameter based on the room temperature, the room condensation temperature and the preset return difference temperature.

[0103] It can be understood that regarding the above-mentioned preset dead-band temperature, it is possible to reduce the situation where the current room condensation risk parameter fluctuates repeatedly above and below the preset condensation risk parameter. The preset dead-band temperature can be obtained by pre-setting, and it can be obtained through experiments or can be an empirical value. The embodiments of the present application do not specifically limit the magnitude of the preset dead-band temperature.

[0104] In addition, it can be understood that regarding the above-mentioned room condensation temperature, it can be calculated based on the air temperature and air humidity in the room. The embodiments of the present application do not specifically limit the method for obtaining the room condensation temperature.

[0105] As Figure 4 shown, Figure 4 is a flowchart of a mixing water control method provided by another embodiment of the present application; regarding the above step S220, it may include but is not limited to step S410 and step S420.

[0106] Step S410, determining the condensation temperature includes the room surface condensation temperature;

[0107] Step S420, determining the current room surface condensation risk parameter according to the room temperature and the room surface condensation temperature.

[0108] In one embodiment, when the condensation temperature is the room surface condensation temperature, for example, when the condensation temperature is the condensation temperature at the inner wall of the room, the embodiments of the present application can calculate the current room condensation risk parameter based on the room temperature and the room surface condensation temperature.

[0109] It can be understood that regarding the above-mentioned room surface condensation temperature, it can be calculated based on the temperature and air humidity at the inner wall of the room. The embodiments of the present application do not specifically limit the method for obtaining the room surface condensation temperature.

[0110] In one embodiment, the preset condensation risk parameter includes one of the following: the first room condensation risk parameter corresponding to the current room condensation risk parameter, and the first room surface condensation risk parameter corresponding to the current room surface condensation risk parameter.

[0111] Specifically, since the condensation temperature may include the room condensation temperature and / or the room surface condensation temperature, correspondingly, the preset condensation risk parameter may include the first room condensation risk parameter and / or the first room surface condensation risk parameter. Specifically, in the embodiments of the present application, the current condensation risk parameter may be determined according to the room temperature and the room condensation temperature, and when the current condensation risk parameter is less than the first room condensation risk parameter, the valve opening of the mixing water device may be controlled according to the current condensation risk parameter; in addition, in the embodiments of the present application, the current condensation risk parameter may also be determined according to the room temperature and the room surface condensation temperature, and when the current condensation risk parameter is less than the first room surface condensation risk parameter, the valve opening of the mixing water device may be controlled according to the current condensation risk parameter.

[0112] It should be noted that when the current room condensation risk parameter is less than the first room condensation risk parameter, for the control of the valve opening of the mixing water device according to the current condensation risk parameter in step S230 above, it may include but is not limited to Figures 5 to 7 the following three implementation cases, specifically as follows:

[0113] As Figure 5 shown, Figure 5 is a flowchart of a mixing water control method provided by another embodiment of the present application; for the control of the valve opening of the mixing water device according to the current condensation risk parameter in step S230 above, it may include but is not limited to step S510 and step S520.

[0114] Step S510, determine that the current condensation risk parameter has not continuously or cumulatively been less than the second room condensation risk parameter for the first preset duration;

[0115] Step S520, keep the valve opening of the mixing water device unchanged, where the second room condensation risk parameter is less than the first room condensation risk parameter.

[0116] In one embodiment, if the duration for which the current condensation risk parameter is less than the second room condensation risk parameter has not continuously or cumulatively reached the first preset duration, it can be considered that the condensation risk is relatively low at this time. Then, the embodiments of the present application will control the valve opening of the mixing water device to remain unchanged.

[0117] It can be understood that for the above-mentioned first preset duration, it can be preset, and it can be obtained through experiments or be an empirical value. The embodiments of the present application do not specifically limit the magnitude of the first preset duration.

[0118] As Figure 6 shown, Figure 6It is a flowchart of the mixing water control method provided by another embodiment of the present application; regarding controlling the valve opening of the mixing water device according to the current condensation risk parameter in the above step S230, it may include but is not limited to step S610 and step S620.

[0119] Step S610: Determine that the current condensation risk parameter continuously or cumulatively is less than the condensation risk parameter of the second room for the first preset duration, and does not continuously or cumulatively be less than the condensation risk parameter of the third room for the second preset duration;

[0120] Step S620: Take the valve opening of the mixing water device after the first preset duration as the maximum limit opening, where the condensation risk parameter of the third room is less than that of the second room.

[0121] In one embodiment, if the current condensation risk parameter is less than the condensation risk parameter of the second room and at least continuously or cumulatively reaches the first preset duration, and the duration that the current condensation risk parameter is less than the condensation risk parameter of the third room does not continuously or cumulatively reach the second preset duration, it can be considered that the condensation risk is medium at this time. Then, the embodiment of the present application will take the valve opening of the mixing water device after the first preset duration as the maximum limit opening, and in subsequent control, the valve opening of the mixing water device cannot be greater than this maximum limit opening.

[0122] It can be understood that regarding the above second preset duration, it can be preset, and it can be obtained through experiments or be an empirical value. The embodiment of the present application does not specifically limit the magnitude of the second preset duration.

[0123] As Figure 7 shown, Figure 7 It is a flowchart of the mixing water control method provided by another embodiment of the present application; regarding controlling the valve opening of the mixing water device according to the current condensation risk parameter in the above step S230, it may include but is not limited to step S710 and step S720.

[0124] Step S710: Determine that the current condensation risk parameter continuously or cumulatively is less than the condensation risk parameter of the third room for the second preset duration;

[0125] Step S720: Close the valve opening of the mixing water device to make the mixing water device enter the bypass state.

[0126] In one embodiment, if the current condensation risk parameter is less than the condensation risk parameter of the third room and at least continuously or cumulatively reaches the second preset duration, it can be considered that the condensation risk is high at this time. Then, the embodiment of the present application will close the valve opening of the mixing water device to make the mixing water device enter the bypass state.

[0127] In addition, in one embodiment, regarding the magnitude relationship between the first preset duration and the second preset duration, since the first preset duration corresponds to the condensation risk parameter of the second room, and the second preset duration corresponds to the condensation risk parameter of the third room, where the condensation risk parameter of the third room is less than that of the second room, and since the lower the risk difference, the shorter the timing, therefore, the second preset duration is less than the first preset duration.

[0128] It should be noted that when the current room condensation risk parameter is less than the surface condensation risk parameter of the first room, regarding controlling the valve opening of the mixing water device according to the current condensation risk parameter in step S230 above, it may include but is not limited to Figures 8 to 10 the three implementation cases in

[0129] As Figure 8 shown, Figure 8 is a flowchart of a mixing water control method provided by another embodiment of the present application; regarding controlling the valve opening of the mixing water device according to the current condensation risk parameter in step S230 above, it may include but is not limited to step S810 and step S820.

[0130] Step S810, determine that the current condensation risk parameter has not continuously or cumulatively been less than the surface condensation risk parameter of the second room for a third preset duration;

[0131] Step S820, keep the valve opening of the mixing water device unchanged, where the surface condensation risk parameter of the second room is less than that of the first room.

[0132] In one embodiment, if the duration during which the current condensation risk parameter is less than the surface condensation risk parameter of the second room has not continuously or cumulatively reached the third preset duration, it can be considered that the condensation risk is relatively low at this time. Then, the embodiment of the present application will control the valve opening of the mixing water device to remain unchanged.

[0133] It can be understood that regarding the above-mentioned third preset duration, it can be preset, and it can be obtained through experiments or be an empirical value. The embodiment of the present application does not specifically limit the magnitude of the third preset duration.

[0134] As Figure 9 shown, Figure 9 is a flowchart of a mixing water control method provided by another embodiment of the present application; regarding controlling the valve opening of the mixing water device according to the current condensation risk parameter in step S230 above, it may include but is not limited to step S910 and step S920.

[0135] Step S910, determine that the current condensation risk parameter continuously or cumulatively is less than the surface condensation risk parameter of the second room for a third preset duration, and has not continuously or cumulatively been less than the surface condensation risk parameter of the third room for a fourth preset duration;

[0136] Step S920: Use the valve opening of the mixing water device after the third preset duration as the maximum limit opening, where the surface condensation risk parameter of the third room is less than that of the second room.

[0137] In an embodiment, if the current condensation risk parameter is less than the surface condensation risk parameter of the second room and lasts or accumulates for at least the third preset duration, and the duration for which the current condensation risk parameter is less than the surface condensation risk parameter of the third room does not last or accumulate for the fourth preset duration, it can be considered that the condensation risk is medium at this time. Then, the embodiment of the present application will use the valve opening of the mixing water device after the third preset duration as the maximum limit opening, and control the valve opening of the mixing water device not to be greater than this maximum limit opening in the subsequent process.

[0138] It can be understood that regarding the above-mentioned second preset duration, it can be preset, and it can be obtained through experiments or be an empirical value. The embodiment of the present application does not specifically limit the magnitude of the second preset duration.

[0139] As Figure 10 shown, Figure 10 is a flowchart of a mixing water control method provided by another embodiment of the present application; regarding controlling the valve opening of the mixing water device according to the current condensation risk parameter in step S230 above, it may include but is not limited to steps S1010 and S1020.

[0140] Step S1010: Determine that the current condensation risk parameter lasts or accumulates for the fourth preset duration and is less than the surface condensation risk parameter of the third room;

[0141] Step S1020: Close the valve opening of the mixing water device to make the mixing water device enter the bypass state.

[0142] In an embodiment, if the current condensation risk parameter is less than the surface condensation risk parameter of the third room and lasts or accumulates for at least the fourth preset duration, it can be considered that the condensation risk is high at this time. Then, the embodiment of the present application will close the valve opening of the mixing water device to make the mixing water device enter the bypass state.

[0143] In addition, in an embodiment, regarding the magnitude relationship between the third preset duration and the fourth preset duration, since the third preset duration corresponds to the surface condensation risk parameter of the second room and the fourth preset duration corresponds to the surface condensation risk parameter of the third room, where the surface condensation risk parameter of the third room is less than that of the second room, and since the lower the risk difference, the shorter the timing, therefore, the fourth preset duration is less than the third preset duration.

[0144] In addition, as Figure 11 shownFigure 11 It is a flowchart of a mixing water control method provided by another embodiment of the present application; the mixing water control method may further include, but is not limited to, step S1110 and step S1120.

[0145] Step S1110: When the current condensation risk parameter is greater than or equal to the preset condensation risk parameter, obtain the target room temperature.

[0146] Step S1120: Control the valve opening of the mixing water device according to the target room temperature and the room temperature.

[0147] In one embodiment, first, the embodiments of the present application obtain the room temperature and the condensation temperature; then, compare and calculate the room temperature and the condensation temperature to obtain the current condensation risk parameter; next, compare the current condensation risk parameter with the preset condensation risk parameter. If the current condensation risk parameter is greater than or equal to the preset condensation risk parameter, it indicates that there is no current condensation risk. At this time, the embodiments of the present application adjust the valve opening of the mixing water device based on the difference between the target room temperature and the room temperature, so as to adjust the ratio of the inlet water flow and the return water flow, and further be able to adjust to obtain a suitable mixing water temperature.

[0148] It can be understood that regarding the above-mentioned method for obtaining the target room temperature, it can be obtained by the user inputting through a remote control, or by the user inputting through a mobile phone, or by the user inputting through a voice method, or by other obtaining methods. The embodiments of the present application do not specifically limit the above-mentioned method for obtaining the target room temperature.

[0149] It should be noted that regarding the control of the valve opening of the mixing water device according to the target room temperature and the room temperature in the above step S1120, it may include, but is not limited to Figures 12 to 14 the following three implementation cases, specifically as follows:

[0150] As Figure 12 shown, Figure 12 It is a flowchart of a mixing water control method provided by another embodiment of the present application; regarding the above step S1120, it may include, but is not limited to, step S1210 and step S1220.

[0151] Step S1210: When the difference between the target room temperature and the room temperature is the first temperature difference;

[0152] Step S1220: Increase the valve opening of the mixing water device and shorten the valve adjustment period of the mixing water device.

[0153] As Figure 13 shown, Figure 13It is a flowchart of a mixing water control method provided by another embodiment of the present application; regarding the above step S1120, it may include but is not limited to step S1310 and step S1320.

[0154] Step S1310: When the difference between the room target temperature and the room temperature is the second temperature difference;

[0155] Step S1320: Extend the valve adjustment period of the mixing water device, where the second temperature difference is less than the first temperature difference.

[0156] As Figure 14 shown, Figure 14 It is a flowchart of a mixing water control method provided by another embodiment of the present application; regarding the above step S1120, it may include but is not limited to step S1410 and step S1420.

[0157] Step S1410: When the difference between the room target temperature and the room temperature is the third temperature difference;

[0158] Step S1420: Close the valve opening of the mixing water device to make the mixing water device enter the bypass state, where the third temperature difference is less than the second temperature difference.

[0159] In one embodiment, based on the above Figures 12 to 14 shown method steps, if the difference between the room target temperature and the room temperature is the first temperature difference, that is, when the difference between the room target temperature and the room temperature is large, shorten the valve opening adjustment period and at the same time increase the valve proportional opening to make the room temperature quickly approach the room target temperature.

[0160] In one embodiment, if the difference between the room target temperature and the room temperature is the second temperature difference, that is, when the difference between the room target temperature and the room temperature is medium, extend the valve opening adjustment period to slow down the change of the water temperature in the room pipeline.

[0161] In one embodiment, if the difference between the room target temperature and the room temperature is the third temperature difference, that is, when the difference between the room target temperature and the room temperature is small and the room is about to reach the temperature, at this time, control the valve opening to 0% to make the valve enter the bypass state, block the inlet water flow, and at the same time turn off the circulating water pump, and use the remaining temperature of the room water circuit to radiate into the room to achieve the energy-saving effect.

[0162] In addition, as Figure 15 shown, Figure 15 It is a flowchart of a mixing water control method provided by another embodiment of the present application; before executing the above step S220, this mixing water control method may further include but is not limited to step S1510 and step S1520.

[0163] Step S1510: Receive a fault signal;

[0164] Step S1520: Fully open the valve opening of the mixing water device according to the fault signal, so that the mixing water device enters the direct-through state.

[0165] In one embodiment, after startup, the embodiment of the present application will determine whether there is a fault in the system. If a fault signal is received, it indicates that there is a fault in the system. At this time, the present application will fully open the valve opening of the mixing water device so that the mixing water device enters the direct-through state and shields the mixing water function.

[0166] It should be noted that regarding the type of the above-mentioned fault signal, it can be a communication failure fault signal, a sensor fault signal, or other types of fault signals. The embodiment of the present application does not make specific limitations on this.

[0167] Based on the mixing water control methods of the above various embodiments, the overall embodiments of the mixing water control method of the present application are respectively proposed below.

[0168] As Figure 16 shown, Figure 16 is the overall flowchart of the mixing water control method provided by another embodiment of the present application; this overall flowchart includes but is not limited to the following steps:

[0169] Step S1610: Start;

[0170] Step S1620: Receive instructions and parameters from the control host;

[0171] Step S1630: Determine whether a fault occurs. When a fault occurs, execute Step S1640; otherwise, execute Step S1650;

[0172] Step S1640: Fault handling, and execute Step S1680;

[0173] Step S1650: Determine whether there is a risk of condensation. If so, execute Step S1660; otherwise, execute Step S1670;

[0174] Step S1660: Condensation risk opening processing, and execute Step S1680;

[0175] Step S1670: Normal opening processing, and execute Step S1680;

[0176] Step S1680: End.

[0177] In one embodiment, first, in step S1620, the mixing water controller receives data from the control host, including instructions to turn on or off the mixing water function, set the cooling or heating mode, and parameters such as the target mixing water temperature Tws, room temperature Tr, room condensation temperature Tdew, and room surface condensation temperature Tsur. The mixing water controller automatically adjusts the opening of the proportional valve according to the above instructions and parameters under different environments. In step S1630, the mixing water controller determines whether there is a fault. If there is a communication failure with the control host, a failure of the actuator or the mixing water temperature sensor, etc., the fault process in step S1640 is followed, and the valve opening is maintained at 100% opening, making the valve in a direct-through state and shielding the mixing water function. When the result of the determination in step S1630 is "no", it is further determined in step S1650 whether there is a condensation risk. If the determination result is "yes", then in step S1660, the condensation risk is further evaluated and processed, otherwise the valve opening is normally controlled according to step S1670.

[0178] In addition, on the premise of no condensation risk, the valve opening is adjusted according to step S1670. When the difference between the room target temperature Ts and the room temperature Tr is ΔT1 (i.e., the above-mentioned first temperature difference), the valve opening adjustment cycle is shortened, and at the same time, the valve proportional opening is increased to quickly bring the room temperature close to the room target temperature; when the difference between the room target temperature Ts and the room temperature Tr is ΔT2 (i.e., the above-mentioned second temperature difference), the valve opening adjustment cycle is extended to slow down the change of the water temperature in the room pipeline; when the difference between the room target temperature Ts and the room temperature Tr is ΔT3 (i.e., the above-mentioned third temperature difference), it indicates that the room is about to reach the temperature with a ΔT3 temperature difference. At this time, the valve opening is controlled to 0%, making the valve enter the bypass state, blocking the inlet water flow, and at the same time turning off the circulating water pump, using the remaining temperature of the room water circuit to radiate to the room to achieve an energy-saving effect. Among them, the room temperature difference relationship is ΔT3 < ΔT < ΔT1, that is, the smaller the temperature difference, the lower the valve adjustment frequency and the smaller the proportional adjustment.

[0179] As Figure 17 shown, Figure 17 is a flowchart for judging the anti-condensation requirement of the mixing water control method provided by another embodiment of the present application, including but not limited to the following steps:

[0180] Step S1710, start;

[0181] Step S1720, calculate the room condensation risk value ΔDr = Tr - Tdew + Td;

[0182] Step S1730, determine whether ΔDr < ΔDr1 is satisfied. If yes, execute step S1740, otherwise execute step S1750;

[0183] Step S1740, set the room condensation flag Fdr = 1, and execute step S1790;

[0184] Step S1750: Set the room condensation flag Fdr = 0, and calculate the room surface condensation risk value ΔDsur = Tr - Tsur;

[0185] Step S1760: Determine whether ΔDsur < ΔDsur1 is satisfied. If yes, execute Step S1770; otherwise, execute Step S1780;

[0186] Step S1770: Set the room surface condensation flag Fsur = 1, and execute Step S1790;

[0187] Step S1780: Set the room surface condensation flag Fsur = 0, and execute Step S1790;

[0188] Step S1790: End.

[0189] In an embodiment, first, in Step S1720, calculate the result ΔDr of adding the difference between the room temperature Tr and the room condensation temperature Tdew and the room condensation risk return difference Td. If ΔDr is less than the parameter condensation risk difference ΔDr1 (i.e., the above-mentioned first room condensation risk parameter), that is, the result of Step S1730 is "yes", then set the room condensation flag Fdr to 1, indicating that there is a room condensation risk; otherwise, clear the room condensation flag Fdr in Step S1750, and calculate the room surface condensation risk value ΔDsur through the room temperature Tr and the room surface condensation temperature Tsur.

[0190] Next, if ΔDsur is less than the parameter ΔDsur1 (i.e., the above-mentioned first room surface condensation risk parameter), that is, the result of Step S1760 is "yes", then set the room surface condensation flag Fsur to 1, indicating that there is a room surface condensation risk; otherwise, clear the room surface condensation flag Fsur.

[0191] As Figure 18 shown, Figure 18 is the flowchart of the anti-condensation treatment of the mixing water control method provided by another embodiment of the present application, including but not limited to the following steps:

[0192] Step S1810: Start;

[0193] Step S1820: Determine whether the room condensation flag Fdr = 1 is satisfied. If yes, execute Step S1831; otherwise, execute Step S1841;

[0194] Step S1831: Determine whether ΔDr < ΔDr3 and lasts for at least t2 time. If yes, execute Step S1834; otherwise, execute Step S1832;

[0195] Step S1832: Determine whether ΔDr < ΔDr2 and it lasts for at least t1 time. If so, execute Step S1833; otherwise, execute Step S1850;

[0196] Step S1833: Use the valve opening at time t1 as the maximum opening limit value, and execute Step S1850;

[0197] Step S1834: Close the proportional valve, and execute Step S1850;

[0198] Step S1841: Determine whether the room surface condensation flag Fsur = 1. If so, execute Step S1842; otherwise, execute Step S1850;

[0199] Step S1842: Determine whether ΔDsur < ΔDsur3 and it lasts for at least t4 time. If so, execute Step S1845; otherwise, execute Step S1843;

[0200] Step S1843: Determine whether ΔDsur < ΔDsur2 and it lasts for at least t3 time. If so, execute Step S1844; otherwise, execute Step S1850;

[0201] Step S1844: Use the valve opening at time t3 as the maximum opening limit value, and execute Step S1850;

[0202] Step S1845: Close the proportional valve, and execute Step S1850;

[0203] Step S1850: End.

[0204] In an embodiment, if the result of Step S1820 is "yes", enter the room anti-condensation process. If ΔDr is less than ΔDr3 (i.e., the above-mentioned third room condensation risk parameter) and it lasts for at least t2 time (i.e., the above-mentioned second preset duration), that is, the result of Step S1831 is "yes", indicating a high room condensation risk, enter Step S1834, directly control the valve opening to 0%, make the valve enter the bypass state, block the water inlet flow, raise the room temperature, and avoid room condensation; if the result of Step S1831 is "no", further determine whether ΔDr is less than ΔDr2 (i.e., the above-mentioned second room condensation risk parameter) and it lasts for at least t1 time (i.e., the above-mentioned first preset duration), that is, if the result of Step S1832 is "yes", record the valve opening at time t1 as the valve maximum opening P1. When the room condensation flag Fdr is 1, the valve opening cannot exceed P1 and can only be maintained or reduced. During the room anti-condensation process, the relationship between the condensation risk differences is ΔDr3 < ΔDr2 < ΔDr1, and the time relationship is t2 < t1, that is, the lower the risk difference, the shorter the timing.

[0205] If the result of step S1820 is "No", further judge the room surface condensation flag, that is, if the result of step S1841 is "Yes", further evaluate the condensation risk. If ΔDsur is less than ΔDsur3 (i.e., the above-mentioned third room surface condensation risk parameter) and lasts for at least t4 time (i.e., the above-mentioned fourth preset duration), that is, if the result of step S1842 is "Yes", it indicates a high room condensation risk, and enter the processing flow of step S1845.

[0206] If the result of step S1842 is "No", further judge whether Dsur is less than ΔDsur2 (i.e., the above-mentioned second room surface condensation risk parameter) and lasts for at least t3 time (i.e., the above-mentioned third preset duration), that is, if the result of step S1843 is "Yes", record the valve opening at the moment of t3 as the maximum valve opening P2. When the room surface condensation flag Fsur is 1, the valve opening cannot exceed P2 and can only be maintained or decreased. During the room surface anti-condensation process, the relationship of the condensation risk difference is ΔDsur3 < ΔDsur2 < ΔDsur1, and the time relationship is t4 < t3, that is, the lower the risk difference, the shorter the timing.
