[0002] In the field of smart homes, temperature control of the same temperature-regulated space (such as a room, office, or specific area) can be achieved through fan coil units placed above the indoor environment and / or floor heating coils placed under the floor. As in existing heat pump systems, appropriate valves control the flow of cold and hot water into the fan coil units and / or floor heating coils to assist in achieving temperature control schemes for either cooling or heating modes.

[0003] However, in related technologies, the adjustment and control of cooling or heating modes in heat pump systems are usually achieved by controlling each valve separately and independently to realize the adjustment and control of cooling or heating modes respectively. However, this control method cannot meet the user's need to quickly and efficiently achieve the required indoor temperature. Summary of the Invention

[0031] The embodiments of this application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this application and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, the accompanying drawings only show the parts related to the embodiments of this application, not all structures. Those skilled in the art, after reading this specification, should be able to conceive that any combination of technical features can constitute an optional implementation method, provided that the technical features do not contradict each other.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship. In the description of this application, "multiple" means two or more, and "several" means one or more.

[0033] In some smart home scenarios, underfloor heating pipes are laid beneath the floor in rooms or offices to regulate the floor temperature by supplying water at the appropriate temperature, thereby affecting the indoor temperature. Fans are also installed at the ceiling, supplying water at the appropriate temperature to fan coil units so that the fans can output hot or cold air, thus influencing the indoor temperature. In other words, indoor temperature regulation can be achieved through fan coil units positioned above the indoor environment and / or underfloor heating pipes.

[0034] However, in related technologies, the adjustment of cooling or heating modes in heat pump systems configured for the above scenarios is usually controlled independently by a single valve. This control strategy often results in slow changes in room temperature and high energy consumption, failing to meet users' demands for faster and more efficient indoor temperature regulation.

[0035] To address this issue, this application provides a temperature-coordinated regulation method applied to a temperature control device in a heat pump system. The heat pump system includes a fan, a fan coil unit, a first valve, a grounding pipe, a second valve, and a temperature control device. The first valve controls the entry of cold or hot water into the fan coil unit to regulate the output of cold or hot air from the fan. The second valve controls the entry of cold or hot water into the grounding pipe to control the temperature supplied by the grounding pipe. The temperature control device controls the opening and closing of the first and second valves. Furthermore, the temperature control device utilizes multiple temperature sensors to detect temperature parameters such as outdoor ambient temperature, water supply temperature, and indoor temperature.

[0036] Figure 1 The diagram illustrates the steps of a temperature coordinated regulation method according to an embodiment of this application, wherein the specific steps are as follows:

[0037] Step S110: Obtain the outdoor ambient temperature and water supply temperature, and determine the start priority of the corresponding second valve based on the outdoor ambient temperature and water supply temperature.

[0038] The activation priority of the second valve corresponds to the control priority of its two states. For example, the second valve has a closed state and an open state. When the second valve is closed, water supply (cold or hot water) can enter the fan coil unit; when the second valve is open, water supply cannot enter the fan coil unit. Therefore, corresponding control parameters are set for each of the two states of the second valve to determine which state of the second valve should be prioritized. Similarly, for the first valve, when it is closed, water supply can enter the fan coil unit; when it is open, water supply cannot enter the fan coil unit.

[0039] The temperature control device determines the activation priority of the second valve by detecting the outdoor ambient temperature and the water supply temperature. For example, in one embodiment, the temperature control device has a first set temperature threshold corresponding to the outdoor ambient temperature and a second set temperature threshold corresponding to the water supply temperature. After acquiring the outdoor ambient temperature and the water supply temperature, the temperature control device compares the outdoor ambient temperature with the first set temperature threshold and compares the water supply temperature with the second set temperature threshold to determine the activation priority of the second valve based on the comparison results.

[0040] Specifically, when the outdoor ambient temperature is less than the first set temperature threshold and the water supply temperature is less than the second set temperature threshold, the temperature control device determines that the activation priority of the second valve is the first priority corresponding to the open state; in other cases, the activation priority of the second valve is the second priority corresponding to the closed state. That is, when the outdoor ambient temperature is greater than or equal to the first set temperature threshold and / or the water supply temperature is greater than or equal to the second set temperature threshold, the temperature control device determines that the activation priority of the second valve is the second priority corresponding to the closed state.

[0041] Step S120: Detect the fan speed status to determine whether the fan is in automatic fan speed mode.

[0042] It can be inferred that the fan speed status includes automatic speed status, low speed status, medium speed status, and high speed status. That is, the fan speed status corresponds to the fan speed mode. For example, when the fan's current speed mode is high speed mode, the corresponding fan speed status is high speed status. The temperature control equipment can determine the fan speed status by detecting the fan speed and the fan speed mode.

[0043] Step S130: When the fan is in automatic fan speed mode, select the constant temperature shutdown hysteresis of the corresponding temperature regulation mode based on the current temperature regulation mode of the heat pump system.

[0044] This means that the temperature control device has corresponding constant temperature shutdown hysteresis settings for different temperature adjustment modes. As we can imagine, the temperature adjustment modes include cooling and heating modes. For cooling mode, the temperature control device has a cooling constant temperature shutdown hysteresis setting, and for heating mode, it has a heating constant temperature shutdown hysteresis setting. With the fan in automatic fan speed mode, after selecting the corresponding constant temperature shutdown hysteresis, the temperature control device can combine the preset temperature value and the constant temperature shutdown hysteresis setting to set multiple room temperature ranges, thereby determining the range within which the monitored indoor temperature falls.

[0045] Step S140: Monitor the indoor temperature in real time and determine the corresponding indoor temperature change trend based on the changes in the indoor temperature within a preset time period.

[0046] The temperature control device monitors the indoor temperature in real time to determine its change over a preset time period, i.e., the temperature trend. This trend indicates whether the indoor temperature is rising or falling within the preset time period. In some embodiments, it's conceivable that two indoor temperatures, corresponding to the initial and final detection times, can be compared to determine whether the temperature trend is rising or falling, with a preset time interval between the initial and final detection times. Alternatively, in some embodiments, the average of multiple indoor temperatures detected over the entire preset time period can be taken, and this average value can be compared with the indoor temperature value obtained at the initial detection time to determine whether the temperature trend is rising or falling.

[0047] Step S150: Based on the preset temperature value and constant temperature shutdown hysteresis of the corresponding indoor temperature setting, determine the set room temperature ranges to determine the target room temperature range of the currently monitored indoor temperature.

[0048] It is conceivable that after determining the constant temperature shutdown hysteresis, the temperature control device, in conjunction with the preset temperature value set for the indoor temperature, i.e. the temperature value that the user needs to achieve for the indoor environment, uses the constant temperature shutdown hysteresis as the difference between the two ends of each room temperature range. Thus, with the preset temperature value as the starting point of a room temperature range, multiple room temperature ranges are set to facilitate the determination of the target room temperature range where the currently detected indoor temperature is located.

[0049] Step S160: Based on the temperature change trend, target room temperature range, and start-up priority, determine the corresponding adjustment strategy to control the fan, the first valve, and the second valve.

[0050] After determining the target room temperature range corresponding to the current indoor temperature, and considering the temperature change trend and activation priority within that range, a corresponding adjustment strategy is determined. It's understood that different room temperature ranges correspond to different temperature change trends, requiring different adjustment strategies for the temperature control equipment. The specific adjustment strategy needs to be determined based on the activation priority. However, each adjustment strategy involves controlling the fan, the first valve, and the second valve, such as controlling the fan speed, the opening or closing of the first valve, and the opening or closing of the second valve. The control of the second valve, in particular, needs to be determined based on the activation priority.

[0051] The temperature control device records a variety of adjustment strategies. By judging the above conditions, the temperature control device selects the corresponding adjustment strategy and then controls the fan, the first valve and the second valve to perform corresponding actions to achieve state switching.

[0052] As can be seen from the above scheme, this scheme determines the activation priority of opening or closing the second valve by detecting the outdoor ambient temperature and the water supply temperature, and determines the current room temperature range based on the monitoring of the indoor temperature. Based on the temperature change trend corresponding to the indoor temperature, the first valve controlling the water inlet of the fan coil unit and the second valve controlling the water inlet of the ground coil unit are linked for control, so as to achieve the required indoor temperature more quickly and efficiently, which helps to further reduce energy consumption.

[0053] It should be noted that the steps shown in the above embodiments are used to represent different steps and to limit the execution order of the steps. In some embodiments, the same technical effect can be achieved by changing the execution order of some steps.

[0054] In some embodiments, the room temperature ranges set in the cooling and heating modes are arranged in ascending order to determine the order of each room temperature range. Therefore, when the start-up priorities are the same, the adjustment strategy for the current room temperature range corresponding to the cooling trend is the same as the adjustment strategy for the next room temperature range corresponding to the ascending trend. For example, if room temperature range I is placed after room temperature range II, and all temperatures in room temperature range I are greater than all temperature values ​​in room temperature range II, then this is the next room temperature range after room temperature range II. Consequently, when the start-up priorities are the same, the adjustment strategy for the cooling trend in room temperature range II is the same as the adjustment strategy for the ascending trend in room temperature range I.

[0055] In one embodiment, for the heating mode, when the start-up priority is the second priority corresponding to the closed state, the temperature control device needs to determine the selected adjustment strategy based on the target room temperature range and the corresponding temperature change trend. Figure 2This is a schematic diagram illustrating the steps for selecting an adjustment strategy according to an embodiment of this application. The specific steps are as follows:

[0056] Step S210: If the temperature change trend is an upward trend when the target room temperature range is the first temperature range, then the adjustment strategy is determined to be the target adjustment strategy.

[0057] Step S220: If the temperature change trend is a cooling trend when the target room temperature range is the second temperature range, then the adjustment strategy is determined to be the target adjustment strategy.

[0058] The first temperature range and the second temperature range are any two adjacent room temperature ranges within the heating mode, and all temperature values ​​within the first temperature range are greater than all temperature values ​​within the second temperature range. It is understood that when the room temperature ranges determined in the heating mode are sorted according to their temperature increase order, the first temperature range corresponds to the second temperature range.

[0059] Furthermore, if the target room temperature range is the first temperature range, and the temperature trend is an upward trend, then the adjustment strategy is determined to be the target adjustment strategy. The target adjustment strategy is the preset adjustment strategy that corresponds to the first temperature range.

[0060] Specifically, since the activation priority is the second priority corresponding to the closed state, the second valve is closed accordingly. Therefore, for each adjustment strategy, arranged in the cooling order of the corresponding room temperature range, the strategies are as follows: the first strategy is to control the fan to be in the off-speed state, the first valve to be in the open state, and the second valve to be in the closed state; the second strategy is to control the fan to be in the off-speed state, the first valve to be in the closed state, and the second valve to be in the closed state; the third strategy is to control the fan to be in the low-speed state, the first valve to be in the closed state, and the second valve to be in the closed state; the fourth strategy is to control the fan to be in the medium-speed state, the first valve to be in the closed state, and the second valve to be in the closed state; and the fifth strategy is to control the fan to be in the high-speed state, the first valve to be in the closed state, and the second valve to be in the closed state.

[0061] For example, a temperature control device might divide the heating mode into five room temperature ranges, arranged in the order of temperature increase: room temperature range V, room temperature range IV, room temperature range III, room temperature range II, and room temperature range I. It's conceivable that the maximum temperature value within room temperature range I is the aforementioned preset temperature value. Correspondingly, in a cooling trend, the adjustment strategy for room temperature range I is strategy one, for room temperature range II it's strategy two, for room temperature range III it's strategy three, for room temperature range IV it's strategy four, and for room temperature range V it's strategy five. Conversely, in a heating trend, the adjustment strategy for room temperature range I is strategy two, for room temperature range II it's strategy three, for room temperature range III it's strategy four, and for room temperature range IV it's strategy five.

[0062] It should be noted that in some embodiments, if the start priority is the first priority corresponding to the disconnected state, the valve state of the second valve in the above-mentioned adjustment strategy is replaced with the disconnected state.

[0063] Figure 3 This diagram illustrates the adjustment strategies corresponding to different room temperature ranges under the heating mode provided in an embodiment of this application. Arrows indicate heating or cooling trends; specifically, dashed lines with arrows represent cooling trends, and solid lines with arrows represent heating trends. When the activation priority is the second priority corresponding to the closed state, as shown in the diagram, if the target room temperature range is room temperature range I and the temperature change trend is cooling, the adjustment strategy is determined to be the first strategy, i.e., the fan is controlled to be off, the first valve is open, and the second valve is closed. If the target room temperature range is room temperature range I and the temperature change trend is heating, the adjustment strategy is determined to be the second strategy, i.e., the fan is controlled to be off, the first valve is closed, and the second valve is closed.

[0064] If the target room temperature range is room temperature range II, and the temperature change trend is a cooling trend, then the adjustment strategy is determined to be the second strategy; if the target room temperature range is room temperature range II, and the temperature change trend is a heating trend, then the adjustment strategy is determined to be the third strategy, that is, controlling the fan to a low wind speed state, the first valve to a closed state, and the second valve to a closed state.

[0065] If the target room temperature range is within room temperature range III, and the temperature change trend is a cooling trend, then the adjustment strategy is determined to be the third strategy; if the target room temperature range is within room temperature range III, and the temperature change trend is a heating trend, then the adjustment strategy is determined to be the fourth strategy, that is, controlling the fan to be in a medium wind speed state, the first valve to be in a closed state, and the second valve to be in a closed state.

[0066] If the target room temperature range is IV, and the temperature trend is decreasing, then the adjustment strategy is determined to be the fourth strategy; if the target room temperature range is IV, and the temperature trend is increasing, then the adjustment strategy is determined to be the fifth strategy, that is, controlling the fan to a high speed, the first valve to be closed, and the second valve to be closed.

[0067] If the target room temperature range is V, and the temperature trend is downward, then the fifth regulation strategy is selected. It should be noted that the interval sizes of each room temperature range can be equal or unequal; the interval sizes can be set according to actual application requirements. Furthermore, when the activation priority changes, the valve state of the second valve in the regulation strategy also changes accordingly to achieve more efficient temperature regulation.

[0068] Therefore, corresponding to the heating mode, the temperature control device sets several room temperature ranges below the preset temperature value, and assigns different adjustment strategies to each room temperature range set in the heating mode. After determining the room temperature range where the indoor temperature is located, the temperature control device controls the fan, the first valve and the second valve according to the corresponding adjustment strategy to achieve linkage control, thereby better adjusting the indoor temperature to the preset temperature value.

[0069] In one embodiment, for the cooling mode, when the start-up priority is the second priority corresponding to the closed state, the temperature control device needs to determine the selected adjustment strategy based on the target room temperature range and the corresponding temperature change trend. Figure 4 A schematic diagram illustrating the steps for selecting an adjustment strategy according to another embodiment of this application is shown below:

[0070] Step S410: If the temperature change trend is a cooling trend when the target room temperature range is the third temperature range, then the adjustment strategy is determined to be the target adjustment strategy.

[0071] Step S420: If the temperature change trend is an upward trend when the target room temperature range is the fourth temperature range, then the adjustment strategy is determined to be the target adjustment strategy.

[0072] The third and fourth temperature ranges are any two adjacent room temperature ranges within the cooling mode, with each temperature value within the third range being lower than each temperature value within the fourth range. It is understood that when the room temperature ranges defined in the cooling mode are sorted according to their heating order, the fourth temperature range corresponds to the third temperature range.

[0073] Furthermore, if the target room temperature range is the third temperature range, and the temperature change trend is a decreasing trend, then the adjustment strategy is determined to be the target adjustment strategy. The target adjustment strategy is the pre-set adjustment strategy corresponding to the third temperature range. The adjustment strategy corresponding to the increasing temperature trend within the fourth temperature range is also this target adjustment strategy.

[0074] Specifically, since the activation priority is the second priority corresponding to the closed state, the second valve is closed accordingly. Therefore, for each regulation strategy, arranged in the order of temperature rise within the corresponding room temperature range, the strategies are as follows: the sixth strategy, which controls the fan to low speed, the first valve to be open, and the second valve to be closed; the seventh strategy, which controls the fan to low speed, the first valve to be closed, and the second valve to be closed; the eighth strategy, which controls the fan to medium speed, the first valve to be closed, and the second valve to be closed; and the ninth strategy, which controls the fan to high speed, the first valve to be closed, and the second valve to be closed.

[0075] For example, a temperature control device might divide the cooling mode into five room temperature ranges, arranged in order of temperature increase: range VI, range VII, range VIII, range IX, and range X. It's conceivable that the minimum temperature within range VI is the preset temperature value mentioned above. Correspondingly, in a cooling trend, the adjustment strategy for range VI is strategy six, for range VII it's strategy seven, for range VIII it's strategy eight, and for range IX it's strategy nine. Conversely, in a heating trend, the adjustment strategy for range VII is strategy six, for range VIII it's strategy seven, for range IX it's strategy eight, and for range X it's strategy nine.

[0076] It should be noted that in some embodiments, if the start priority is the first priority corresponding to the disconnected state, the valve state of the second valve in the above-mentioned adjustment strategy is replaced with the disconnected state.

[0077] Figure 5 This diagram illustrates the adjustment strategies for different room temperature ranges under a cooling mode provided in an embodiment of this application. Arrows indicate heating or cooling trends; specifically, dashed lines with arrows represent cooling trends, and solid lines with arrows represent heating trends. When the activation priority is the second priority corresponding to the closed state, as shown in the diagram, if the temperature change trend is a cooling trend when the target room temperature range is room temperature range VI, then the adjustment strategy is determined to be the sixth strategy, i.e., controlling the fan to a low speed state, the first valve to be open, and the second valve to be closed.

[0078] If the target room temperature range is room temperature range VII, and the temperature change trend is an upward trend, then the adjustment strategy is determined to be the sixth strategy; if the target room temperature range is room temperature range VII, and the temperature change trend is a downward trend, then the adjustment strategy is determined to be the seventh strategy, that is, controlling the fan to a low wind speed state, the first valve to a closed state, and the second valve to a closed state.

[0079] If the target room temperature range is room temperature range VIII, and the temperature change trend is an upward trend, then the adjustment strategy is determined to be strategy seven; if the target room temperature range is room temperature range VIII, and the temperature change trend is a downward trend, then the adjustment strategy is determined to be strategy eight, that is, controlling the fan to be in medium wind speed state, the first valve to be in closed state, and the second valve to be in closed state.

[0080] If the target room temperature range is IX, and the temperature trend is upward, then the adjustment strategy is determined to be strategy eight. If the target room temperature range is IX, and the temperature trend is downward, then the adjustment strategy is determined to be strategy nine, i.e., controlling the fan to high speed, the first valve to be closed, and the second valve to be closed. If the target room temperature range is X, and the temperature trend is upward, then the adjustment strategy is determined to be strategy nine.

[0081] It is understandable that there are similar strategies among the above-mentioned adjustment strategies. Correspondingly, in order to clearly illustrate this scheme under different temperature adjustment modes, the Nth strategy and the Mth strategy are used to describe the same state control scheme, where N and M represent different numbers.

[0082] Therefore, in the corresponding cooling mode, the temperature control device sets several room temperature ranges above the preset temperature value, and assigns different adjustment strategies to each room temperature range set in the cooling mode. After determining the room temperature range where the indoor temperature is located, the temperature control device controls the fan, the first valve and the second valve according to the corresponding adjustment strategy to achieve linkage control, thereby better adjusting the indoor temperature to the preset temperature value.

[0083] In some embodiments, if the temperature control device receives a control signal to enter high-efficiency mode before or during the execution of the adjustment strategy, it enters high-efficiency mode and thereby upgrades the adjustment strategy corresponding to each room temperature range. It is conceivable that the control signal for entering high-efficiency mode could be input by the user via keypad input, or it could be transmitted by the user to the temperature control device via a remote control using wireless transmission technologies such as infrared or Bluetooth.

[0084] Understandably, temperature control devices have different adjustment levels for different adjustment strategies. For example, in heating mode, the room temperature range set in the temperature control device is below the preset temperature value; that is, the temperature values ​​within each room temperature range are less than or equal to the preset temperature value. As the room temperature decreases and falls into another room temperature range, the corresponding adjustment strategy is upgraded. Therefore, when the temperature control device receives a control signal to enter high-efficiency mode, it adopts the next higher adjustment strategy as the current adjustment strategy, that is, the adjustment strategy corresponding to the lower room temperature range. Of course, the adjustment strategy before and after upgrading corresponds to the same temperature change trend.

[0085] Therefore, through the high-efficiency mode, the temperature control device can adjust the indoor temperature more quickly and efficiently to meet the user's needs for adjusting the indoor temperature, and also helps to reduce energy consumption.

[0086] In one embodiment, the room temperature ranges in the heating mode are arranged in order of temperature increase. Correspondingly, if the selected temperature adjustment mode is the heating mode, the adjustment strategy corresponding to the cooling trend in the previous room temperature range is selected as the adjustment strategy corresponding to the cooling trend in the current room temperature range, and the adjustment strategy corresponding to the heating trend in the previous room temperature range is selected as the adjustment strategy corresponding to the heating trend in the current room temperature range.

[0087] For example, if the startup priority is the first priority, room temperature range I and room temperature range II are two adjacent room temperature ranges, and room temperature range II is the room temperature range preceding room temperature range I, that is, all temperature values ​​in room temperature range I are greater than all temperature values ​​in room temperature range II.

[0088] If the target room temperature range is room temperature range I, and the temperature change trend is a cooling trend, then the adjustment strategy is determined to be the first strategy, that is, controlling the fan to be in the off state, the first valve to be in the open state, and the second valve to be in the open state; if the target room temperature range is room temperature range I, and the temperature change trend is a heating trend, then the adjustment strategy is determined to be the second strategy, that is, controlling the fan to be in the off state, the first valve to be in the closed state, and the second valve to be in the open state.

[0089] If the target room temperature range is room temperature range II, and the temperature change trend is a cooling trend, then the adjustment strategy is determined to be the second strategy; if the target room temperature range is room temperature range II, and the temperature change trend is a heating trend, then the adjustment strategy is determined to be the third strategy, that is, controlling the fan to a low wind speed state, the first valve to a closed state, and the second valve to a closed state.

[0090] Furthermore, during the adjustment process, i.e. after entering the high-efficiency mode, if the temperature trend is decreasing within the room temperature range I, the adjustment strategy is determined to be the second strategy, i.e., the fan is controlled to be in the off-speed state, the first valve is in the closed state, and the second valve is in the open state; if the temperature trend is increasing, the adjustment strategy is determined to be the third strategy, i.e., the fan is controlled to be in the low-speed state, the first valve is in the closed state, and the second valve is in the open state.

[0091] In one embodiment, the room temperature ranges in the cooling mode are arranged in order of temperature increase. Correspondingly, if the selected temperature regulation mode is the cooling mode, the regulation strategy corresponding to the cooling trend in the next room temperature range is selected as the regulation strategy corresponding to the cooling trend in the current room temperature range, and the regulation strategy corresponding to the heating trend in the next room temperature range is selected as the regulation strategy corresponding to the heating trend in the current room temperature range.

[0092] For example, if the startup priority is the first priority, room temperature range VII and room temperature range VIII are two adjacent room temperature ranges, and room temperature range VIII is the next room temperature range after room temperature range VII, that is, each temperature value in room temperature range VIII is greater than each temperature value in room temperature range VII.

[0093] If the target room temperature range is room temperature range VII, and the temperature change trend is an upward trend, then the adjustment strategy is determined to be the sixth strategy; if the target room temperature range is room temperature range VII, and the temperature change trend is a downward trend, then the adjustment strategy is determined to be the seventh strategy, that is, controlling the fan to a low wind speed state, the first valve to a closed state, and the second valve to a closed state.

[0094] If the target room temperature range is room temperature range VIII, and the temperature change trend is an upward trend, then the adjustment strategy is determined to be strategy seven; if the target room temperature range is room temperature range VIII, and the temperature change trend is a downward trend, then the adjustment strategy is determined to be strategy eight, that is, controlling the fan to be in medium wind speed state, the first valve to be in closed state, and the second valve to be in open state.

[0095] Furthermore, during the adjustment process, i.e. after entering the high-efficiency mode, if the temperature trend is decreasing within the room temperature range VII, the adjustment strategy is determined to be the eighth strategy, i.e., the fan is controlled at medium speed, the first valve is closed, and the second valve is open; if the temperature trend is increasing, the adjustment strategy is determined to be the seventh strategy, i.e., the fan is controlled at low speed, the first valve is closed, and the second valve is open.

[0096] Figure 6This is a schematic diagram of a temperature coordination regulation device provided in an embodiment of this application. The device is used to execute the temperature coordination regulation method provided in the above embodiment and has the corresponding functional modules and beneficial effects. The device is applied to a temperature control device in a heat pump system.

The first valve controls the entry of cold or hot water into the fan coil unit, and the second valve controls the entry of cold or hot water into the ground coil. As shown in the figure, the temperature coordination regulation device includes a priority determination module 601, a wind speed detection module 602, a hysteresis selection module 603, a room temperature detection module 604, a range selection module 605, and a regulation control module 606.

[0097] The priority determination module 601 is configured to acquire the outdoor ambient temperature and water supply temperature to determine the start priority of the corresponding second valve based on these temperatures. The wind speed detection module 602 is configured to detect the wind speed status of the fan to determine whether the fan is in automatic wind speed mode. The hysteresis selection module 603 is configured to select the constant temperature shutdown hysteresis of the corresponding temperature regulation mode based on the current temperature regulation mode of the heat pump system when the fan is in automatic wind speed mode. The room temperature detection module 604 is configured to monitor the indoor temperature in real time and determine the temperature change trend of the corresponding indoor temperature based on the changes in the indoor temperature within a preset time period. The range selection module 605 is configured to determine the set room temperature ranges based on the preset temperature value and constant temperature shutdown hysteresis of the corresponding indoor temperature to determine the target room temperature range of the currently monitored indoor temperature. The adjustment control module 606 is configured to determine the corresponding adjustment strategy based on the temperature change trend, the target room temperature range, and the start priority to control the fan, the first valve, and the second valve.

[0098] Based on the above embodiments, the temperature control device is provided with a first set temperature threshold corresponding to the outdoor ambient temperature and a second set temperature threshold corresponding to the water supply temperature, and the priority determination module 601 is further configured as follows:

[0099] After determining the current outdoor ambient temperature and water supply temperature, compare the outdoor ambient temperature with the first set temperature threshold, the water supply temperature with the second set temperature threshold.

[0100] When the outdoor ambient temperature is lower than the first set temperature threshold and the water supply temperature is lower than the second set temperature threshold, the activation priority of the second valve is determined to be the first priority corresponding to the disconnection state.

[0101] When the outdoor ambient temperature is greater than or equal to the first set temperature threshold and / or the water supply temperature is greater than or equal to the second set temperature threshold, the activation priority of the second valve is determined to be the second priority corresponding to the closed state.

[0102] Based on the above embodiments, the temperature adjustment mode includes a heating mode and a cooling mode. When the order of the room temperature ranges corresponding to the heating mode and the cooling mode is arranged according to the heating order and the start priority is the same, the adjustment strategy for the cooling trend corresponding to the current room temperature range is the same as the adjustment strategy for the heating trend corresponding to the room temperature range in the next order.

[0103] Based on the above embodiments, in heating mode, the adjustment control module 606 is further configured as follows:

[0105] If the temperature change trend is a cooling trend when the target room temperature range is the second temperature range, then the regulation strategy is determined to be the target regulation strategy.

[0106] Wherein, the first temperature range and the second temperature range are any two adjacent room temperature ranges in each room temperature range under the heating mode, and each temperature value in the first temperature range is greater than each temperature value in the second temperature range. The target adjustment strategy is the adjustment strategy corresponding to the first temperature range among a number of preset adjustment strategies.

[0107] The adjustment strategies, arranged in descending order according to the corresponding room temperature range, are as follows:

[0108] The first strategy controls the fan to be in the off-speed state, the first valve to be in the open state, and the second valve to be in the target state, where the target state is the valve state corresponding to the start-up priority;

[0109] The second strategy is to control the fan to the off-speed state, the first valve to the closed state, and the second valve to the target state.

[0111] The fourth strategy is to control the fan to a medium wind speed, the first valve to be closed, and the second valve to be in the target state.

[0112] The fifth strategy involves controlling the fan to a high-speed state, the first valve to be closed, and the second valve to the target state.

[0115] If the temperature change trend is an upward trend when the target room temperature range is the fourth temperature range, then the regulation strategy is determined to be the target regulation strategy.

[0116] Among them, the third temperature range and the fourth temperature range are any two adjacent room temperature ranges in the cooling mode, and the temperature values ​​in the third temperature range are all lower than the temperature values ​​in the fourth temperature range. The target adjustment strategy is the adjustment strategy corresponding to the third temperature range among several preset adjustment strategies.

[0117] The adjustment strategies, arranged in the order of temperature increase along the corresponding room temperature range, are as follows:

[0118] The sixth strategy is to control the fan to a low wind speed state, the first valve to be in the open state, and the second valve to be in the target state, where the target state is the valve state corresponding to the start-up priority.

[0119] The seventh strategy is to control the fan to a low wind speed state, the first valve to be closed, and the second valve to the target state.

[0120] The eighth strategy is to control the fan to medium wind speed, the first valve to be closed, and the second valve to the target state.

[0121] The ninth strategy involves controlling the fan to a high-speed state, the first valve to be closed, and the second valve to the target state.

The order of the room temperature ranges corresponding to the heating mode and the cooling mode is arranged according to the temperature rise sequence. The step-up adjustment module is also configured as follows:

[0125] If the temperature regulation mode used is heating mode, then the regulation strategy corresponding to the cooling trend in the previous room temperature range is selected as the regulation strategy corresponding to the cooling trend in the current room temperature range, and the regulation strategy corresponding to the heating trend in the previous room temperature range is selected as the regulation strategy corresponding to the heating trend in the current room temperature range.

[0126] If the temperature regulation mode used is cooling mode, the regulation strategy corresponding to the cooling trend in the next room temperature range is selected as the regulation strategy corresponding to the cooling trend in the current room temperature range, and the regulation strategy corresponding to the heating trend in the next room temperature range is selected as the regulation strategy corresponding to the heating trend in the current room temperature range.
