Abstract
Description
Technical Field
[0001] The present application relates to the field of intelligent device technology, for example, to methods, devices, equipment and storage media for controlling heat pump temperature control equipment. Background Art
[0002] Heat pump thermostat is a combined heat and cooling product that achieves both heating and cooling functions through one system. Specifically, combined heat and cooling products usually use one or more heat pump hosts as cold and heat sources to provide solutions for cooling and heating needs in buildings.
[0003] Due to its comfort and energy-saving advantages, dual-generation products have been loved by more and more users in recent years, and the market size has developed rapidly. Similar to but different from traditional fluorine machines, the water pump, water system, compressor and other facilities of the heat pump temperature control equipment are more susceptible to damage. Especially when the heat pump temperature control equipment is in heating mode, a temperature shutdown condition may occur. At this time, the compressor is shut down and the water pump is turned off. Since the water cannot flow after the water pump is turned off, the local water temperature varies greatly due to the different heat dissipation speeds at various locations in the equipment, and there is a risk of freezing in the outdoor water pipes. At the same time, the water temperature detected by the water temperature sensor in the water circuit cannot accurately reflect the overall status, which may also cause the outdoor unit to be unable to restart in time. Therefore, the water pump, water system, compressor and other facilities may be damaged.

[0043] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure.

It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.
[0045] Unless otherwise stated, the term "plurality" means two or more.
[0046] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.
[0047] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.
[0048] The heat pump thermostat is a dual-generation product, including: compressor, water pump, water system and other facilities, and the heat pump host can be used as a cold and heat source to achieve the two functions of heating and cooling. In the embodiment of the present disclosure, the heat pump thermostat is in the heating mode. When the compressor is in the running state, when the working temperature obtained meets the temperature shutdown condition, not only the compressor is controlled to be in the shutdown state, but also the water pump is controlled to be in the open state, and one or more water channels are controlled to be in the open state. In this way, after the compressor is shut down, the water pump and the water channel are kept conductive, and the high-temperature water in the buffer water tank can continue to heat the terminal or the room. Thus, after the water in the equipment is circulated, the probability of the risk of local heat dissipation leading to ice and freezing of water system facilities is reduced, and the stability and service life of the heat pump thermostat is improved. At the same time, the overall water temperature change when the compressor is in the shutdown state can also be accurately detected to ensure that the compressor can be restarted in time, further guaranteeing the heating effect of the heat pump thermostat and improving the efficacy of the heat pump thermostat. In addition, when the compressor is stopped, the indoor temperature of each room or terminal can be monitored, and the water circuit can be switched according to the indoor temperature to ensure that the temperature fluctuations in each room are smooth and improve the user experience. At the same time, the heat in the buffer water tank can be fully utilized to reduce the number of restarts of the outdoor unit and reduce energy consumption.
[0049] Figure 1 Schematic diagram of a scenario architecture of a heat pump temperature control device provided by an embodiment of the present disclosure. Figure 1As shown, the heat pump external unit of the heat pump temperature control device includes a compressor 100 and a water pump 200. The water outlet of the water pump 200 is connected to the water distributor 300 through a pipe equipped with corresponding valves. In this way, it is divided into multiple waterways. After the pipe of each waterway passes through each corresponding room or terminal, it passes through the water collector 400, the buffer water tank 500, and the pipe equipped with corresponding valves, and is connected to the water inlet of the water pump 200. That is, the heat pump temperature control device includes: a compressor, a water pump, and multiple waterways, wherein each waterway flows through a corresponding room or terminal. The switch state control of each waterway can be achieved by controlling the solenoid valve corresponding to each channel on the water distributor.
[0050] The heat pump outdoor unit can be used as a cold and heat source to achieve both heating and cooling functions. In the disclosed embodiment, the heat pump temperature control device is in heating mode, and the risk of freezing of water system facilities can be reduced by controlling the compressor, water pump, and the switch state of the water circuit, and the number of restarts of the outdoor unit and energy consumption can be reduced.
[0051] Figure 2 FIG. 1 is a flow chart of a method for controlling a heat pump temperature control device provided by an embodiment of the present disclosure. Figure 1 and Figure 2 As shown, when the heat pump temperature control device is in heating mode, the control process of the heat pump temperature control device includes:
[0052] Step 201: When the compressor is in operation, obtain a first current operating temperature.
[0053] After the heat pump thermostat is started, it will monitor various working temperatures, and control one, two or more facilities such as the compressor, water pump, and waterway according to the monitored working temperatures. Therefore, when the compressor in the heat pump outdoor unit of the heat pump thermostat is in operation, various working temperatures will also be monitored, that is, the first working temperature will be obtained. Since the heat pump thermostat can be monitored in real time or at a fixed time during the startup and operation of the heat pump thermostat, the first working temperature obtained at the current moment is the first current working temperature.
[0054] Since the operating temperature includes: the outlet water temperature and return water temperature of the water pump, the indoor temperature corresponding to each room or terminal, etc., one, two or more, therefore, the first current operating temperature may include: the first current water pump outlet water temperature, the first current indoor temperature, etc., one, two or more. If the application scenario of the heat pump temperature control device includes one, two or more rooms or terminals, the first current operating temperature may also include: one, two or more first current indoor temperatures. Figure 1 As shown, the first current operating temperature may include five first current indoor temperatures.
[0055] Step 202: When it is determined that the first current operating temperature satisfies the warm shutdown condition, the compressor is controlled to be in a shutdown state.
[0056] During the heating operation, the heat pump temperature control equipment will experience a temperature shutdown phenomenon, that is, when the first current operating temperature obtained meets the temperature shutdown condition, the compressor will stop running. The temperature shutdown can include: water temperature reaching temperature shutdown, or room temperature reaching temperature shutdown.
[0057] In some embodiments, determining that the first current operating temperature satisfies the thermal shutdown condition includes: when the first current water pump outlet water temperature included in the first current operating temperature is greater than or equal to the first set temperature, determining that the first current operating temperature satisfies the thermal shutdown condition, wherein the first set temperature is the sum of the target outlet water temperature and the outlet water return temperature, or the first set temperature is the maximum safe outlet water temperature; when the first current indoor temperature of each room or terminal included in the first current operating temperature is greater than or equal to the corresponding second set temperature, determining that the first current operating temperature satisfies the thermal shutdown condition, wherein the second set temperature is the sum of the corresponding target indoor temperature and the room temperature return temperature.
[0058] If the first set temperature is the sum of the target outlet water temperature and the outlet water return temperature, that is, T1 = target outlet water temperature T tar-w + Water outlet temperature difference ΔT w At this time, the first current water pump outlet water temperature T act-w ≥T1, it can be determined that the first current operating temperature meets the temperature shutdown condition, and the compressor can be controlled to be in a shutdown state, that is, the water temperature reaches the temperature shutdown condition.
[0059] If the first set temperature is the highest safe water outlet temperature T max-w When T1 = T max-w At this time, the first current water pump outlet water temperature T act-w ≥T1, it can be determined that the first current operating temperature meets the temperature shutdown condition, and the compressor can be controlled to be in a shutdown state, that is, the water temperature reaches the temperature shutdown condition.
[0060] Of course, the target water outlet temperature T tar-w , outlet water return temperature ΔT w , and T max-w They can all be set according to the performance of the heat pump temperature control equipment, application scenarios, etc.
[0061] In the embodiment of the present disclosure, the room temperature may also be stopped. In this way, if the application scenario of the heat pump temperature control device includes n rooms or terminals, the first current indoor temperature corresponding to each room or terminal may be T act-a i, where i = 1, 2, ... n, and each room or terminal also corresponds to a target indoor temperature T tar-aThe return temperature difference between i and room temperature ΔT a i, so the second set temperature T2i = T tar-a i+ΔT a i; and if each T act-a When i≥T2i is satisfied, it can be determined that the first current operating temperature meets the temperature shutdown condition, and the compressor can be controlled to be in a shutdown state, that is, the room temperature reaches the temperature shutdown condition. Figure 1 As shown, the first current operating temperature includes: the first current indoor temperature T act-a 1. First, the current indoor temperature T act-a 2. First, the current indoor temperature T act- a 3. First, the current indoor temperature T act-a 4. And, first, the current indoor temperature T act-a 5. If T act-a 1≥T21,T act-a 2≥T22, T act-a 3 ≥ T23, T act-a 4 ≥ T24, T act-a 5≥T25, it can be determined that the first current operating temperature meets the warm shutdown condition, and the compressor can be controlled to be in a shutdown state.
[0062] Similarly, the target indoor temperature T tar-a The return temperature difference between i and room temperature ΔT a i can be set according to the performance of the heat pump temperature control equipment, user needs, application scenarios, etc.
[0063] Step 203: When the compressor is in a stopped state, control the water pump to be in an open state, and control one or more water channels to be in an open state.
[0064] In the disclosed embodiment, when the compressor stops when the temperature reaches a certain level, the water pump does not stop, but is controlled to be in an on state. Since the heat pump temperature control device has one, two or more water channels, each of which flows through a corresponding room or terminal, one or more water channels can be controlled to be in an on state in order to take into account both energy consumption and water channel freezing protection.
[0065] Different temperature-reaching shutdown modes may have different corresponding water circuit control modes. Among them, when the water temperature reaches the temperature-reaching shutdown mode, each water circuit may be controlled to maintain the corresponding switch state before the compressor is shut down, that is, in some embodiments, under the working condition corresponding to the first current water pump outlet water temperature, the first switch state corresponding to each water circuit is obtained; and each water circuit is controlled to maintain the corresponding first switch state. Since the first current water pump outlet water temperature is greater than or equal to the first set temperature, that is, when it is determined that the first current working condition temperature meets the temperature shutdown condition, the first switch state corresponding to each water circuit at this time is obtained, and then each water circuit is controlled to maintain the corresponding first switch state.
[0066] like Figure 1 As shown, the first current water pump outlet water temperature T act-w ≥T1, if the solenoid valves corresponding to the first channel, the second channel and the fifth channel of the water distributor are in the open state, and the solenoid valves corresponding to the third channel and the fourth channel are in the closed state, that is, the first switch state corresponding to each water channel can be the first water channel, the second water channel and the fifth water channel are in the open state, and the third water channel and the fourth water channel are in the closed state. At this time, because the water temperature reaches the temperature, the heat pump temperature control device turns off the compressor in the heat pump outdoor unit, not only controls the water pump to be in the open state, but also can still control the solenoid valves corresponding to the first channel, the second channel and the fifth channel to be in the open state, and control the solenoid valves corresponding to the third channel and the fourth channel to be in the closed state, that is, control each water channel to maintain the corresponding first switch state.
[0067] The water temperature shutdown is often for the protection of the unit and water system facilities. The actual room temperature has not yet reached the corresponding target temperature. Therefore, after the compressor is shut down, the water pump and water circuit are kept open, and the high-temperature water in the buffer water tank can continue to heat the terminal or room. After the water in the system circulates, the risk of local heat dissipation leading to ice and freezing of water system facilities is reduced.
[0068] When the room temperature reaches the required temperature and the compressor is shut down, the water circuit corresponding to the last room or terminal that reaches the required temperature can be controlled to be in an open state, and the other water circuits can be controlled to be in a closed state. In addition, during the shutdown of the compressor, the indoor temperature corresponding to each room or terminal can continue to be monitored, and different water circuits can be switched to an open state according to the indoor temperature. That is, in some embodiments, controlling one or more water circuits to be in an open state includes: upon determining that the first current indoor temperature corresponding to the current room or terminal is greater than or equal to the corresponding second set temperature, if the water circuits corresponding to other rooms or terminals are in a closed state, controlling the water circuit corresponding to the current room or terminal to be in an open state; when the compressor is in a shutdown state, periodically obtaining the second indoor temperature of each room or terminal, and determining that one water circuit is in an open state according to the second indoor temperature.
[0069] Of course, when the first current indoor temperature is not greater than or equal to the corresponding second set temperature, if the first current indoor temperature corresponding to the current room or terminal is greater than or equal to the corresponding second set temperature, the water channel corresponding to the current room or terminal is controlled to be in a closed state.
[0070] like Figure 1 As shown, when the compressor is in operation, the first current operating temperature monitored includes: the first current indoor temperature T act-a 1. First, the current indoor temperature T act-a 2. First, the current indoor temperature T act-a 3. First, the current indoor temperature T act-a4. and the first current indoor temperature T act-a 5. Each first current indoor temperature may not be greater than or equal to the corresponding second set temperature simultaneously. For example, during the current monitoring process, T act-a 1≥T21, T act-a 3≥T23, while T act-a 2<T22, T act-a 4<T24, T act-a 5<T25. At this time, not every first current indoor temperature is greater than or equal to the corresponding second set temperature, that is, the condition for the room temperature to reach the set temperature and stop the machine is not met. At this time, the heat pump temperature control device does not need to control the compressor to stop, but can control the solenoid valves corresponding to the first channel and the third channel in the water distributor to be in the closed state, and control the solenoid valves corresponding to the second channel, the fourth channel, and the fifth channel to be in the open state, that is, control the first water circuit and the third water circuit to be in the closed state. In this way, when monitoring again, among the first current indoor temperatures obtained, not only T act-a 1≥T21, T act-a 3≥T23, and T act-a 2≥T22, T act-a 5≥T25, only T act-a 4<T24. At this time, the solenoid valves corresponding to the first channel and the third channel are in the closed state, then the heat pump temperature control device does not need to control the compressor to stop, but still needs to control the solenoid valves corresponding to the second channel and the fifth channel to be in the closed state, that is, control the second water circuit and the fifth water circuit to be in the closed state. When monitoring again, among the first current indoor temperatures obtained, T act-a 1≥T21, T act-a 2≥T22, T act-a 3≥T23, T act-a 4≥T24, T act-a 5≥T25. It can be determined that the first current operating condition temperature meets the condition for temperature shutdown. At this time, the heat pump temperature control device controls the compressor to stop, and only the solenoid valve corresponding to the fourth channel is in the open state, that is, the fourth water circuit is in the open state, while the water circuits corresponding to other rooms or terminals are all in the closed state. Then, the heat pump temperature control device still controls the solenoid valve corresponding to the fourth channel to be in the open state and keeps the fourth water circuit in the open state.
[0071] Then, when the compressor is in the shutdown state, continue to monitor the indoor temperature of each room or terminal, that is, the second indoor temperature, and according to the second indoor temperature, switch a different water circuit to be in the open state. In some embodiments, determining that a water circuit is in the open state includes: obtaining the current temperature difference between each second current indoor temperature and the corresponding target indoor temperature; controlling the water circuit corresponding to the room or terminal with the smallest current temperature difference to be in the open state, and controlling the water circuits corresponding to other rooms or terminals to be in the closed state.
[0072] Similarly, when the compressor is in the stopped state, the second current indoor temperature corresponding to each room or terminal can be T′ act-a i, and the corresponding target indoor temperature T tar-a i, the current temperature difference between each second current indoor temperature and the corresponding target indoor temperature can be obtained, ΔTi = T′ act-a iT tar-a i, compare ΔTi, determine the water channel corresponding to the minimum ΔTi, and control the water channel to be in an open state.
[0073] like Figure 1 As shown, if ΔT3 is the smallest during the current monitoring process, the heat pump thermostat controls the solenoid valve of the third channel of the water distributor to be in an open state, and the solenoid valves corresponding to other channels are in a closed state, that is, the third waterway is controlled to be in an open state, and the other waterways are in a closed state. When monitoring again, the obtained ΔT5 is the smallest, then the heat pump thermostat controls the solenoid valve of the fifth channel of the water distributor to be in an open state, and the solenoid valves corresponding to other channels are in a closed state, that is, the fifth waterway is controlled to be in an open state, and the other waterways are in a closed state.
[0074] In the disclosed embodiment, when the compressor is in a shutdown state, the period for monitoring and obtaining the second indoor temperature of each room or terminal may be consistent with the period for monitoring the operating temperature of the heat pump temperature control device, or the period for obtaining the second indoor temperature may be set separately, for example: 8, 10, or 15 minutes, etc.
[0075] When the room temperature reaches the temperature and the machine stops, the difference (T′) between the monitored indoor temperature and the target indoor temperature is determined by comparison. act-a -T tar-a )The smallest room or end, switching the water path to this room or end can ensure that the temperature fluctuations in each room are smooth and improve the user experience. At the same time, it can make full use of the heat in the buffer water tank, reduce the number of restarts of the outdoor unit, and reduce energy consumption.
[0076] Of course, the implementation of the present disclosure is not limited to this, and it is also possible to directly determine that a water channel is in an open state based on each second current indoor temperature, for example: control the water channel of the room or terminal corresponding to the minimum second current indoor temperature to be in an open state, and control the water channels corresponding to other rooms or terminals to be in a closed state. Alternatively, the average temperature value is obtained based on each second current indoor temperature, and the absolute difference between each second current indoor temperature and the average temperature value is obtained, the water channel of the room or terminal corresponding to the maximum absolute difference is controlled to be in an open state, and the water channels corresponding to other rooms or terminals are controlled to be in a closed state. The specifics are not listed one by one.
[0077] It can be seen that in the disclosed embodiment, the heat pump temperature control device is in the heating mode. When the compressor is in operation and the operating temperature obtained meets the temperature shutdown condition, not only the compressor is controlled to be in the shutdown state, but also the water pump is controlled to be in the open state, and one or more water channels are controlled to be in the open state. In this way, after the compressor is shut down, the water pump and the water channel are kept conductive, and the high-temperature water in the buffer water tank can continue to heat the terminal or the room. Therefore, after the water in the equipment circulates, the probability of the risk of local heat dissipation leading to freezing and freezing of water system facilities is reduced, thereby improving the stability and service life of the heat pump temperature control device. At the same time, when the compressor is shut down, the indoor temperature corresponding to each room or terminal can also be monitored, and the water channel can be switched according to the indoor temperature to ensure that the temperature fluctuations in each room are smooth and improve the user experience; at the same time, the heat in the buffer water tank can be fully utilized to reduce the number of restarts of the external unit and reduce energy consumption.
[0078] Of course, regardless of whether the compressor is in operation, the heat pump thermostat will monitor various operating temperatures, and when the compressor in the heat pump outdoor unit of the heat pump thermostat is in a shutdown state, various operating temperatures will also be monitored, that is, the second operating temperature is obtained, and the second operating temperature obtained at the current moment is the second current operating temperature. The second operating temperature will also include: one, two or more of the second current water pump outlet temperature, the second current indoor temperature, etc. In this way, if the second current water pump outlet temperature is less than the third set temperature, or there is one, two or more second current indoor temperatures less than the corresponding fourth set temperature, it can be determined that the second current operating temperature meets the outdoor unit restart condition, and the compressor can be controlled to be in operation. That is, in some embodiments, when the compressor is in a shutdown state, the second current operating temperature is obtained; when the second current operating temperature meets the outdoor unit restart condition, the compressor is controlled to be in operation.
[0079] like Figure 1 As shown, the compressor in the heat pump outdoor unit of the heat pump temperature control device is in a stopped state. If the second current water pump outlet water temperature T′ monitored at this time act-w < the third set temperature T3, where T3≤T1, at this time, it can be determined that the second current operating temperature meets the outdoor unit restart condition, and the heat pump temperature control device controls the compressor to be in a running state. Then, the control process of steps 201-203 is continued. Alternatively, the compressor in the heat pump outdoor unit of the heat pump temperature control device is in a stopped state. If any second current indoor temperature T′ is monitored at this time act-a When i<the fourth set temperature T4, T4≤T2, at this time, it can be determined that the second current operating temperature meets the restart condition of the outdoor unit, and the heat pump temperature control device controls the compressor to be in operation.
[0080] In this way, when the compressor is stopped, the water pump is controlled to be in the on state, and one or more water channels are controlled to be in the on state, so that water can circulate in the system. In this way, the overall water temperature change can be accurately detected to ensure that the outdoor unit can be restarted in time.
[0081] The operation flow is collected into a specific embodiment below to illustrate the control process for the heat pump temperature control device provided by the embodiment of the present invention.

[0083] Figure 3-1 , Figure 3-2 1 is a flow chart of a method for controlling a heat pump temperature control device provided by an embodiment of the present disclosure. Figure 1 , Figure 3-1 , Figure 3-2 As shown, the heat pump temperature control equipment control process includes:
[0084] Step 301: The heat pump temperature control device is in hot mode operation.
[0085] Step 302: When the compressor is in operation, the heat pump temperature control device obtains a first current operating temperature.
[0086] Among them, the first current operating temperature includes: the first current water pump outlet water temperature T act-w , and the first current indoor temperature T corresponding to the five rooms or terminals act-a i, where i=1, 2,...5.
[0087] Step 303: Determine the first current water pump outlet water temperature T act-w ≥T1? If yes, go to step 306; otherwise, go to step 304.
[0088] Where T1 = target water outlet temperature T tar-w + Water outlet temperature difference ΔT w , or T1 = Tmax-w 。
[0089] Step 304: Determine whether each first current indoor temperature T act-a i≥T2i holds? If so, execute 311; otherwise, execute Step 305.
[0090] Here, the sequence of Step 303 and Step 304 is not limited. It is also possible to first determine whether T act-a i≥T2i holds? If not, then determine whether T act-w ≥T1 holds?
[0091] Step 305: The heat pump temperature control device determines the room or terminal corresponding to the first current indoor temperature T act-a i that is greater than or equal to the second set temperature as the room or terminal to be controlled, and controls the water circuit corresponding to the room or terminal to be controlled to be in a closed state. Return to Step 302.
[0092] Step 306: The heat pump temperature control device obtains the first switch state corresponding to each water circuit and controls the compressor to be in a shutdown state.
[0093] Step 307: The heat pump temperature control device controls the water pump to be in an open state and controls each water circuit to maintain the corresponding first switch state.
[0094] Step 308: When the compressor is in a shutdown state, the heat pump temperature control device obtains the second current operating condition temperature.
[0095] Of course, the second current operating condition temperature may include: the second current water pump outlet temperature T′ act-w , and the second current indoor temperature T′ act-a corresponding to each of the five rooms or terminals respectively, where i = 1, 2,..., 5.
[0096] Step 309: Determine whether the second current operating condition temperature meets the outdoor unit restart condition? If so, execute Step 310; otherwise, return to Step 308.
[0097] The second current water pump outlet temperature T′ act-w <T3, or, when any one of the second current indoor temperatures T′ act-a i<T4, it can be determined that the second current operating condition temperature meets the outdoor unit restart condition, and execute Step 310.
[0098] Step 310: The heat pump temperature control device controls the compressor to be in an operating state. Return to Step 302.
[0099] Step 311: The heat pump temperature control device controls the compressor to be in a shutdown state and determines the last water circuit in the open state as the water circuit to be controlled.
[0100] Step 312: The heat pump temperature control device controls the water pump to be in the on state, controls the water path to be controlled to be in the on state, and controls the water paths corresponding to other rooms or terminals to be in the off state.
[0101] Step 313: When the compressor is in the shutdown state, the heat pump temperature control device obtains the second current operating condition temperature.
[0102] Similarly, the second current operating condition temperature may include: the second current water pump outlet temperature T′ act-w , and the second current indoor temperatures T′ act-a i corresponding to five rooms or terminals respectively, where i = 1, 2,... 5.
[0103] Step 314: Determine whether the second current operating condition temperature meets the outdoor unit restart condition? If yes, execute Step 315, otherwise, execute Step 316.
[0104] The second current water pump outlet temperature T′ act-w < T3, or, when any one of the second current indoor temperatures T′ act-a i < T4, it can be determined that the second current operating condition temperature meets the outdoor unit restart condition, and execute Step 312.
[0105] Step 315: The heat pump temperature control device controls the compressor to be in the running state. Return to Step 302.
[0106] Step 316: Has the periodic sampling time of ten minutes passed? If yes, execute Step 317, otherwise, return to Step 313.
[0107] Step 317: The heat pump temperature control device obtains the current temperature difference ΔTi between each second current indoor temperature and the corresponding target indoor temperature.
[0108] Where, ΔTi = T′ act-a i - T tar-a i.
[0109] Step 318: The heat pump temperature control device determines the room or terminal corresponding to the minimum current temperature difference as the room or terminal to be controlled, controls the water path corresponding to the room or terminal to be controlled to be in the on state, and controls the water paths corresponding to other rooms or terminals to be in the off state. Return to Step 313.
[0110] It can be seen that in this embodiment, the ice heat pump thermostat is in the heating mode. When the compressor is in the running state, the working temperature obtained meets the temperature shutdown condition, not only the compressor is controlled to be in the shutdown state, but also the water pump is controlled to be in the open state, and one or more water channels are controlled to be in the open state, so that the water pump and the water channel are kept conductive after the compressor is shut down, and the high-temperature water in the buffer water tank can continue to heat the terminal or the room. Thus, after the water in the equipment is circulated, the probability of the risk of local heat dissipation leading to ice and freezing of water system facilities is reduced, and the stability and service life of the heat pump thermostat are improved. At the same time, the overall water temperature change when the compressor is in the shutdown state can also be accurately detected to ensure that the compressor can be restarted in time, further guaranteeing the heating effect of the heat pump thermostat and improving the efficacy of the heat pump thermostat. In addition, when the compressor is in the shutdown state, the indoor temperature corresponding to each room or terminal can also be monitored, and the water channel can be switched according to the indoor temperature to ensure that the temperature fluctuations of each room are smooth, thereby improving the user experience; at the same time, the heat in the buffer water tank can be fully utilized to reduce the number of restarts of the external unit and reduce energy consumption.
[0111] According to the above process for controlling a heat pump temperature control device, a device for controlling a heat pump temperature control device can be constructed.
[0112] Figure 4 1 is a schematic diagram of a heat pump temperature control device provided by an embodiment of the present disclosure. The heat pump temperature control device includes: a compressor, a water pump, and multiple water paths, wherein each water path flows through a corresponding room or terminal, and the heat pump temperature control device is in heating mode. Figure 4 As shown, the heat pump temperature control device 400 includes: a first acquisition module 410, a first control module 420 and a second control module 430.

[0117] The first determination unit is configured to determine that the first current operating condition temperature satisfies the warm shutdown condition when the first current operating condition temperature includes a first current water pump outlet water temperature that is greater than or equal to a first set temperature, wherein the first set temperature is the sum of the target outlet water temperature and the outlet water return temperature, or the first set temperature is the maximum safe outlet water temperature.
[0118] The second determination unit is configured to determine that the first current operating condition temperature satisfies the warm shutdown condition when the first current indoor temperature of each room or terminal included in the first current operating condition temperature is respectively greater than or equal to the corresponding second set temperature, wherein the second set temperature is the sum of the corresponding target indoor temperature and the room temperature return temperature.
[0119] In some embodiments, the first control module 420 includes:
[0120] The first control unit is configured to obtain a first switch state corresponding to each water channel under an operating condition corresponding to a first current water pump outlet water temperature; and control each water channel to maintain the corresponding first switch state.
[0121] In some embodiments, the second control module 430 includes:
[0122] The second control unit is configured to control the water channel corresponding to the current room or terminal to be in an open state when it is determined that the first current indoor temperature corresponding to the current room or terminal is greater than or equal to the corresponding second set temperature and if the water channels corresponding to other rooms or terminals are in a closed state.
[0123] The third control unit is configured to periodically obtain the second indoor temperature of each room or terminal when the compressor is in a stopped state, and determine whether a water path is in an open state based on the second indoor temperature.
[0124] In some embodiments, the third control unit is specifically configured to obtain the current temperature difference between each second current indoor temperature and the corresponding target indoor temperature; control the water circuit of the room or terminal corresponding to the minimum current temperature difference to be in an open state, and control the water circuits corresponding to other rooms or terminals to be in a closed state.
[0125] In some embodiments, it also includes: a third control module, which is configured to control the water channel corresponding to the current room or the terminal to be in a closed state when the first current indoor temperature is not greater than or equal to the corresponding second set temperature and when the first current indoor temperature corresponding to the current room or the terminal is greater than or equal to the corresponding second set temperature.
[0126] In some embodiments, it also includes:
[0127] The second acquisition module is configured to acquire a second current operating temperature when the compressor is in a shutdown state.
[0128] The fourth control module is configured to control the compressor to be in a running state when the second current operating temperature meets the restart condition of the external unit.
[0129] The heat pump temperature control device control process used in the heat pump temperature control device control device is further described below in conjunction with the embodiments.
[0130] In this embodiment, Figure 1 As shown in the figure, the heat pump temperature control equipment includes: compressor, water pump, water distributor, water collector, buffer water tank and various solenoid valves. In this way, the water system of the heat pump temperature control equipment can be divided into five water channels through the water distributor and water collector, and each water channel flows through the corresponding room or terminal. And the target water outlet temperature T is preset. tar-w , outlet water return temperature ΔT w , maximum safe water outlet temperature T max-w , each room or terminal corresponds to the target indoor temperature T tar-a i, room temperature return temperature ΔT a i, i=1, 2, ... 5, that is, the first set temperature T1 and the second set temperature T2 are determined. And T3 and T4 are set, T3≤T1, T4≤T2.
[0131] Figure 5 Schematic diagram of a heat pump temperature control device provided by the embodiment of the present disclosure. Figure 5 As shown, the heat pump temperature control device 400 includes: a first acquisition module 410, a first control module 420, a second control module 430, a third control module 440, a second acquisition module 450 and a fourth control module 460. Among them, the first control module 420 includes: a first determination unit 421 and a second determination unit 422. The second control module 430 includes: a first control unit 431, a second control unit 432, and a third control unit 433.
[0132] In this embodiment, after the heat pump temperature control device is in the hot mode, when the compressor is in the running state, the first acquisition module 410 acquires the first current operating temperature. The first current operating temperature includes: the first current water pump outlet water temperature T act-w , and the first current indoor temperature T corresponding to the five rooms or terminals act-a i, where i=1, 2,...5.
[0133] During the shutdown process of the heat pump temperature control equipment, if the first current water pump outlet water temperature T act-wIf it is ≥T1, the first determination unit 421 in the first control module 420 can determine that the first current operating condition temperature meets the temperature shutdown condition, and the first control module 420 can control the compressor to be in a shutdown state. The second control module 430 controls the water pump to be in an on state, and after obtaining the first switch state corresponding to each water circuit, the first control unit 431 in the second control module 430 controls each water circuit to maintain the corresponding first switch state.
[0134] After the compressor shuts down, when the compressor is in a shutdown state, the second acquisition module 450 acquires the second current operating condition temperature. Similarly, the second current operating condition temperature may include: the second current water pump outlet temperature T′ act-w , and the second current indoor temperature T′ corresponding to each of the five rooms or terminals act-a i, where i = 1, 2,..., 5.
[0135] Thus, if the second current water pump outlet temperature T′ act-w <T3, or, any one of the second current indoor temperatures T′ act- a i < T4, the fourth control module 460 determines that the second current operating condition temperature meets the outdoor unit restart condition and can control the compressor to be in an operating state.
[0136] During the process of the water temperature of the heat pump temperature control device reaching the temperature shutdown, if each first current indoor temperature T act-a i ≥ T2i holds, the second determination unit 422 in the first control module 420 can determine that the first current operating condition temperature meets the temperature shutdown condition, and then the first control module 420 can control the compressor to be in a shutdown state. The second control module 430 controls the water pump to be in an on state, and after the second control unit 432 determines the last water circuit in the on state as the water circuit to be controlled, it controls the water circuit to be controlled to be in an on state and controls the water circuits corresponding to other rooms or terminals to be in an off state.
[0137] Of course, when not every first current indoor temperature T act-a i ≥ T2i holds, the third control module 440 determines the room or terminal corresponding to the first current indoor temperature T act-a i that is greater than or equal to the second set temperature as the room or terminal to be controlled, and controls the water circuit corresponding to the room or terminal to be controlled to be in an off state.
[0138] After the compressor shuts down, when the compressor is in a shutdown state, the second acquisition module 450 acquires the second current operating condition temperature. Similarly, the second current operating condition temperature may include: the second current water pump outlet temperature T′ act-w , and the second current indoor temperature T′ corresponding to each of the five rooms or terminals act-a i, where i = 1, 2,..., 5.
[0139] In this way, if the outlet water temperature T' of the second current water pump act-w < T3, or any one of the second current indoor temperatures T' act- a < T4, the fourth control module 460 determines that the second current operating condition temperature meets the outdoor unit restart condition, and can control the compressor to be in the operating state.
[0140] If the second current operating condition temperature does not meet the outdoor unit restart condition, but reaches the periodic sampling time interval of ten minutes, after the third control unit 433 in the second control module 430 obtains the current temperature difference ΔTi between each second current indoor temperature and the corresponding target indoor temperature, the room or terminal corresponding to the minimum current temperature difference is determined as the room or terminal to be controlled, and the water circuit corresponding to the room or terminal to be controlled is controlled to be in the open state, and the water circuits corresponding to other rooms or terminals are controlled to be in the closed state.
[0141] It can be seen that in this embodiment, the ice heat pump temperature control device is in the heating mode. The device for controlling the heat pump temperature control device can, when the operating condition temperature obtained when the compressor is in the operating state meets the temperature shutdown condition, not only control the compressor to be in the shutdown state, but also control the water pump to be in the open state, and control one or more water circuits to be in the open state. In this way, after the compressor shuts down, the water pump and the water circuit remain导通, and the high-temperature water in the buffer tank can continue to heat the terminal or the room. Thus, after the water circulation in the device starts, the probability of the risk of freezing due to rapid local heat dissipation and damage to the water circuit system facilities is reduced, and the stability and service life of the heat pump temperature control device are improved. At the same time, the overall water temperature change when the compressor is in the shutdown state can be accurately detected to ensure that the compressor can be restarted in time, further ensuring the heating effect of the heat pump temperature control device and improving the efficiency of the heat pump temperature control device. In addition, when the compressor is in the shutdown state, the device for controlling the heat pump temperature control device can also monitor the indoor temperature corresponding to each room or terminal, and perform water circuit switching according to the indoor temperature to ensure that the temperature fluctuations in each room are gentle, improving the user experience; at the same time, the heat in the buffer tank can be fully utilized to reduce the number of outdoor unit restarts and reduce energy consumption.
