[0085] Please refer to Figure 1 , the present invention provides a room temperature regulation system 100, including a buffer water tank 1, an energy supply device, and a kang body structure 3; the energy supply device includes a solar collector 21, the solar collector 21 forms a first energy supply water flow path, and the water inlet and outlet of the first energy supply water flow path are both connected to the buffer water tank 1; an independent energy storage water flow path 31 and an energy consumption water flow path 32 are formed in the kang body structure 3, a phase change energy storage module is provided in the kang body structure 3, and both the energy storage water flow path 31 and the energy consumption water flow path 32 can exchange heat with the phase change energy storage module. Among them, the water inlet and outlet of the energy storage water flow path are both connected to the buffer water tank 1.

[0086] In the room temperature regulation system provided by the present invention, a phase change energy storage module is arranged in the kang body structure 3, so that the buffer water tank 1 is communicated with the inside of the kang body structure 3. During the heating process of the kang body structure 3, part of the heat will be stored in the phase change energy storage module. At the same time, the energy supply device is also communicated with the buffer water tank 1, so that the buffer water tank 1, the energy supply device and the kang body structure 3 form an integral whole, enabling the entire room temperature regulation system 100 to store heat and allowing the stored heat to be exchanged among various components, without consuming energy to heat up when there is a useful heat demand, thereby reducing energy consumption.

[0087] It should be noted that, in this embodiment, the phase change heat storage module includes a phase change material filled in the kang body structure, which absorbs and releases heat through the phase change material.

[0088] When the water circuit in the room temperature regulation system 100 circulates, the buffer water tank 1 provides a certain volume to facilitate the circulation of the liquid, ensuring that sufficient liquid can be filled in each component within the entire system during the circulation.

[0089] The solar collector 21 can simultaneously heat and dissipate heat from the first energy supply water flow path inside; among them, when there is sunlight outside, the liquid in the first energy supply water flow path is heated by the solar collector 21; when there is no sunlight outside, the liquid in the first energy supply water flow path is dissipated by the solar collector 21, so that the single component of the solar collector 21 can simultaneously achieve the two functions of heating and cooling.

[0090] It should be noted that since the heating effect of the solar collector 21 is limited, in order to ensure that sufficient heat can be provided to the kang body structure 3, an active heating device is also required to heat the liquid in the room temperature regulation system 100.

[0091] Furthermore, the energy supply device further includes a heat pump assembly 22. A second energy supply water flow path is formed on the heat pump assembly 22, and the buffer water tank 1 is also located on the second energy supply water flow path. The second energy supply water flow path can provide heat or cold to the buffer water tank. In this embodiment, through the heat pump assembly 22, heat is actively provided to the second energy supply water flow path for heating or cooling, and then the liquid with the changed temperature is transported into the buffer water tank 1 to participate in the water temperature circulation within the entire room temperature regulation system 100.

[0092] It should be noted that the heat pump assembly 22 has various implementation manners. For example, for heating, a heating device is directly provided, and the liquid in the second energy supply water flow path is heated by means of electric heating or external combustion heating. When cooling is required, the second energy supply water flow path is connected to the underground ice water to achieve cooling.

[0093] In this application, the heat pump assembly 22 includes a heat exchange device, and two heat exchange flow sections that can exchange heat with each other are formed in the heat exchange device; an air-conditioning flow path, on which a compressor, a reversing valve, and a radiator are sequentially arranged, and the air-conditioning flow path includes one of the heat exchange flow sections; the second energy supply water flow path includes the other heat exchange flow section; in this embodiment, through the air-conditioning flow path, the active refrigeration and heating of the heat pump assembly 22 are realized, and automatic electrical control can be realized, which is convenient for the interlocking control with the solar collector 21.

[0094] Furthermore, in order to achieve electrical control, a first water pump is provided on the first energy supply water flow path to control the on-off of the flow path between the solar collector 21 and the buffer water tank 1.

[0095] Similarly, a second water pump is provided on the energy storage water flow path to control the on-off of the flow path between the energy storage water flow path 21 and the buffer water tank 1.

[0096] In addition, a third water pump is provided on the second energy supply water flow path to control the on-off of the flow path between the heat pump assembly 22 and the buffer water tank 1.

[0097] A fourth water pump is provided on the energy consumption water flow path to control the on-off of the energy consumption water flow path.

[0098] It should be noted that in an embodiment provided by the present invention, the first water pump, the second water pump, the third water pump, and the fourth water pump are included at the same time to facilitate the on-off control of all paths.

[0156] Controlling the first water pump to close, the second water pump to close, the third water pump to close, and the fourth water pump to open.

[0157] Optionally, determining the current working mode of the room temperature regulation system includes:

[0159] Associate and store the current positioning information and the weather forecast information;

[0160] Query the mapping relationship according to the current positioning information and the weather forecast information to determine the current working mode of the room temperature regulation system, wherein the mapping relationship is the association relationship between the associated storage of the current positioning information, the weather forecast information, and the current working mode of the room temperature regulation system.

[0161] Based on the above room temperature regulation system, the present invention also provides a control method for room temperature regulation. The control method for room temperature regulation includes the following steps:

[0162] S10. Determine the current working mode of the room temperature regulation system;

[0163] Among them, determining the current working mode of the room temperature regulation system to judge whether it is in the cooling or heating mode at this time, so as to connect the energy supply device and the components in the kang body structure 3 to the buffer water tank according to different working modes respectively for heat circulation.

[0164] S20. Control the first water pump, the second water pump, the third water pump, and the fourth water pump respectively based on the current working mode.

[0165] Among them, by controlling the water pumps, the on-off control of the first energy supply water flow path, the energy storage water flow path, the second energy supply water flow path, and the energy consumption water flow path is realized respectively, ensuring that the heat stored in the phase change energy storage module in the kang body structure 3 can enter the required place according to the demand, making use of the stored heat, and eliminating the need to turn on the heat pump assembly 22 multiple times, thus saving energy.

[0166] In the control method for room temperature regulation provided by the present invention, through the current working mode, the circulation paths of the buffer water tank 1, the energy supply device, and the liquid in the kang body structure in the room temperature regulation system at this time are judged, so as to recycle the heat in the phase change energy storage module to different positions, eliminating the need to turn on the heat pump assembly 22 every time heat is needed, saving energy, reducing the operating cost, and at the same time, the energy supply device can be used to transport and store heat in the phase change energy storage module to realize the cross-time utilization of energy.

[0167] In the room temperature regulation system 100 provided by the present invention, it can be used in the winter heating process. Based on this, the current working mode of the room temperature regulation system includes a heating mode, so as to provide sufficient heat for users in winter.

[0168] Specifically, step S20 includes:

[0169] S21. When the room temperature regulation system is in the heating mode, obtain the current indoor temperature;

[0170] Among them, when heating is required, first obtain the current indoor temperature and determine whether heat needs to be provided to the kang body structure at this time to ensure that the indoor temperature remains comfortable first.

[0171] S22. When the current indoor temperature is lower than the first preset indoor temperature, control the first water pump to turn on, the second water pump to turn on, the third water pump to turn on, and the fourth water pump to turn on;

[0172] Among them, when it is judged that the current indoor temperature is lower than the first preset indoor temperature at this time, it means that the temperature in the room is too cold at this time and the room needs to be heated. Therefore, in this embodiment, the first water pump, the second water pump, and the third water pump are turned on at the same time, so that the solar collector 21, the kang body structure 3, and the heat pump assembly 22 are all connected to the buffer water tank 1, and the liquids in the buffer water tank 1 and the kang body structure 3 are heated simultaneously by the solar collector 21 and the heat pump assembly 22, so that the system in the entire room temperature regulation system can be quickly heated up to meet the temperature requirements of users.

[0173] S23. When the current indoor temperature is higher than the first preset indoor temperature, obtain the current energy storage water temperature on the energy storage water flow path and the current water tank water temperature in the buffer water tank, and control the first water pump, the second water pump, the third water pump, and the fourth water pump according to the current energy storage water temperature and the current water tank water temperature.

[0174] Among them, after gradually heating the liquid in the kang body structure 3, or when the temperature of the indoor environment itself meets the heat extraction requirements, it means that enough heat has been stored in the phase change energy storage module at this time. At the same time, the heat released by the kang body structure 3 to the room environment is relatively low, and the heat stored in the phase change energy storage module can be provided to other components to avoid the need to turn on the heat pump assembly 22 when other components need heat. Furthermore, by judging the water temperature in the buffer water tank 1, it can be determined whether it is necessary to output heat to the buffer water tank 1 through the phase change energy storage module and further provide it outward.

[0175] In this embodiment, by judging the magnitude relationship between the current indoor temperature and the first preset indoor temperature, it is determined whether the phase change energy storage module needs to be supplemented with heat or can provide heat outward through the phase change energy storage module. While ensuring the temperature of the indoor environment, the excess heat stored in the phase change energy storage module can be transported outward, without the need to frequently turn on the heat pump assembly 22, reducing energy consumption and ensuring the comfort of the living environment.

[0176] Based on the above steps, the room temperature regulation system 100 provided by the present invention includes an indoor heating mode;

[0177] A. Indoor heating mode

[0178] When the current indoor temperature is less than the first preset indoor temperature, the room temperature regulation system 100 enters the indoor heating mode, the first water pump is turned on, the second water pump is turned on, the third water pump is turned on, and the fourth water pump is turned on.

[0179] When the indoor temperature meets the requirements, it is necessary to determine whether other positions in the room temperature regulation system 100 require heat. Therefore, further, step S23 includes:

[0180] S231. Determine whether the current energy storage water temperature exceeds the current water tank water temperature to obtain a first judgment result;

[0181] Among them, by judging the current water tank water temperature, it is judged whether heat needs to be transported to the buffer water tank 1.

[0182] S232. Determine whether the current energy supply temperature on the first energy supply water path exceeds the current water tank water temperature to obtain a second judgment result;

[0183] Among them, by comparing the liquid temperatures in the first energy supply water path and the buffer water tank 1, it is judged which of them needs to input heat more, and then according to whether the temperature in the buffer water tank in the first judgment structure can meet the heating demand, it is decided whether to connect the buffer water tank 1 with the solar collector 21 and the buffer water tank 1 with the kang body structure.

[0184] S233. Control the first water pump, the second water pump, the third water pump, and the fourth water pump according to the first judgment result, the second judgment result, and the current water tank water temperature.

[0185] Among them, after obtaining the first judgment result and the second judgment result, the amount of heat that needs to be input or can be output in the buffer water tank 1 at this time can be judged through the current water tank water temperature, and then it is decided whether to connect the solar collector 21 and the kang body structure accordingly.

[0186] Specifically, when the first judgment result is that the current energy storage water temperature is greater than or equal to the current water tank water temperature, and the second judgment result is that the current energy supply temperature is less than the current water tank water temperature;

[0187] In the embodiment provided by the present invention, the temperature inside the kang body structure 3 is the highest, the temperature inside the buffer water tank 1 is lower than that of the kang body structure 3, and the temperature inside the solar collector 21 is lower than that inside the buffer water tank 1. At this time, it should be at night in winter or just after the buffer water tank 1 and the kang body structure 3 have been heated through the above indoor heating mode;

[0188] Therefore, first of all, it is necessary to ensure its anti-freezing at night. Since the solar collector 21 cannot heat the liquid therein through sunlight, at this time, it is necessary to prevent the liquid in the solar collector 21 and the buffer water tank 1 from freezing.

[0189] At the same time, in the case of just completing the heat charging, it is necessary to utilize the excess heat to avoid waste.

[0190] Based on this, in step S233, the following four usage modes are included.

[0191] B. First anti-freezing mode

[0192] Among them, step S233 includes:

[0193] When the current water tank water temperature is less than or equal to the first preset water tank water temperature, control the first water pump to turn on, the second water pump to turn on, the third water pump to turn off, and the fourth water pump to turn on;

[0194] In the first anti-freezing mode, since the temperature inside the buffer water tank 1 is too low and it has a risk of freezing itself, and at the same time, the solar collector 21 also has a risk of freezing, therefore, it is necessary to raise the temperature inside the buffer water tank 1 and the solar collector 21. Therefore, by turning on the second water pump, the heat stored in the kang body structure 3 is transported to the buffer water tank 1 and the solar collector 21 to avoid freezing.

[0195] C. Second anti-freezing mode

[0196] Among them, step S233 includes:

[0197] When the current water tank water temperature is greater than the first preset water tank water temperature and less than or equal to the second preset water tank water temperature, control the first water pump to turn on, the second water pump to turn off, the third water pump to turn off, and the fourth water pump to turn on;

[0198] In the second anti-freezing mode, the buffer water tank 1 has a certain temperature, which can meet its own anti-freezing requirements. At the same time, to prevent freezing in the solar collector 21, the first water pump is turned on to connect the buffer water tank 1 with the solar collector 21, enabling heat to circulate and transfer between the two. The temperature in the buffer water tank 1 is output to the solar collector 21, which can prevent the solar collector 21 from freezing at the same time.

[0199] D. First self-cooling mode

[0200] Among them, step S233 includes:

[0201] When the current water tank water temperature is greater than the second preset water tank water temperature and less than or equal to the third preset water tank water temperature, control the first water pump to close, the second water pump to close, the third water pump to close, and the fourth water pump to turn on;

[0202] In the self-cooling mode, the buffer water tank 1 is in a relatively high temperature state and has no risk of freezing itself, indicating that the buffer water tank 1 should be in a state where it has just completed heating and is in the cooling period. At this time, the entire system remains at a relatively hot level. Therefore, in fact, the entire system has no risk of freezing and no anti-freezing operation is required. At the same time, since the temperature in the buffer water tank 1 is not sufficient to reach the phase change temperature in the kang body structure 3 and cannot heat the kang body structure 3, the first water pump, the second water pump, and the third water pump are all closed, and the kang body structure 3 neither needs to input heat nor output heat.

[0203] E. First water tank heating mode

[0204] Among them, step S233 includes:

[0205] When the current water tank water temperature is greater than the third preset water tank water temperature, control the first water pump to close, the second water pump to turn on, the third water pump to close, and the fourth water pump to turn on.

[0206] In the water tank heating mode, the liquid in the buffer water tank 1 is at a high temperature, and its temperature value has exceeded the phase change temperature of the phase change energy storage module. Therefore, to avoid waste of energy, the high-temperature liquid at this time needs to be injected into the kang body structure 3 to store heat in the kang body structure 3. At this time, the second water pump is turned on to connect the buffer water tank 1 with the kang body structure 3 to input heat into the kang body structure 3.

[0207] On the other hand, when the first judgment result is that the current energy storage water temperature is greater than or equal to the current water tank water temperature, and the second judgment result is that the current energy supply temperature is greater than or equal to the current water tank water temperature;

[0208] In the embodiment provided by the present invention, similarly, the temperature in the kang body structure 3 is the highest. At the same time, the temperature in the solar collector 21 is also higher than that in the buffer water tank 1.

[0209] At this time, it may be daytime in winter, and the heating mode in Room A has been completed. The temperature in the buffer water tank 1 gradually decreases until it is less than that in the solar collector 21. At this time, it is necessary to judge whether heat needs to be introduced to the optimal use position.

[0210] Based on this, in step S233, the following two usage modes are further included.

[0211] F. First water tank heat supplement mode

[0212] Among them, step S233 includes:

[0213] When the current water tank water temperature is less than or equal to the second preset water tank water temperature, control the first water pump to turn on, the second water pump to turn off, the third water pump to turn off, and the fourth water pump to turn on;

[0214] In the water tank heat supplement mode, since the temperature in the buffer water tank 1 is the lowest, and at this time the heat-using components do not need to use heat, the temperature in the solar collector 21 is supplemented to the buffer water tank 1 to maintain the temperature in the buffer water tank 1, avoiding the temperature in the buffer water tank 1 being too low during subsequent use, resulting in the need to waste extra temperature to heat the liquid in the buffer water tank 1.

[0215] G. First linkage heating mode

[0216] Among them, step S233 includes:

[0217] When the current water tank water temperature is greater than the second preset water tank water temperature, control the first water pump to turn on, the second water pump to turn on, the third water pump to turn off, and the fourth water pump to turn on.

[0218] In the first linked heating mode, at this time, the water temperature in the buffer water tank 1 has exceeded the phase change temperature of the phase change material. Therefore, it is necessary to utilize the high temperature in the buffer water tank 1 and the solar collector 21. Therefore, turn on the first water pump and the second water pump, so that the solar collector 21 transfers heat to the buffer water tank 1, and the buffer water tank 1 transfers heat to the kang body structure 3, and stores the heat in the phase change energy storage module to store the high temperature for subsequent utilization.

[0219] On the other hand, when the first judgment result is that the current energy storage water temperature is less than the current water tank water temperature, and the second judgment result is that the current energy supply temperature is less than the current water tank water temperature;

[0220] In this embodiment, the temperature in the buffer water tank 1 is the highest, and it is necessary to consider transferring the temperature in the buffer water tank 1 to the solar collector 21 and the kang body structure 3.

[0221] Based on this, in step S233, the following two usage modes are further included.

[0222] H. Second water tank heat supplement mode

[0223] Among them, step S233 includes:

[0224] When the current water tank water temperature is greater than the first preset water tank water temperature and less than or equal to the second preset water tank water temperature, control the first water pump to turn on, the second water pump to turn off, the third water pump to turn off, and the fourth water pump to turn on;

[0225] In the second water tank heat supplement mode, since the current water tank water temperature is not enough to reach the phase change temperature and cannot effectively supplement heat to the kang body structure 3, and at the same time, since the indoor temperature is sufficient and there is no urgent need to supplement heat to the kang body structure 3, connect the buffer water tank 1 and the solar collector 21 so that the temperature between the two is balanced and exchanged, quickly increasing the temperature in the buffer water tank 1 for subsequent heat supplement to the kang body structure 3.

[0226] I. Second water tank heating mode

[0227] Among them, step S233 includes:

[0228] When the current water tank water temperature is greater than the second preset water tank water temperature, control the first water pump to turn off, the second water pump to turn on, the third water pump to turn off, and the fourth water pump to turn on.

[0229] In the second water tank heating mode, the temperature in the buffer water tank 1 is sufficient to reach the phase change temperature. Therefore, the second water pump is turned on to supplement heat to the kang body structure 3 and store the excess heat to avoid waste of energy.

[0230] On the other hand, when the first judgment result is that the current energy storage water temperature is less than the current water tank water temperature, and the second judgment result is that the current energy supply temperature is greater than or equal to the current water tank water temperature;

[0231] In this embodiment, in the embodiment provided by the present invention, the temperature of the solar collector 21 is greater than that of the buffer water tank 1, and the temperature in the buffer water tank 1 is greater than that of the kang body structure 3. Therefore, it is necessary to consider making use of the excess heat.

[0232] Based on this, in step S233, the following three usage modes are further included.

[0233] J. Third anti-freezing mode

[0234] When the current water tank water temperature is less than or equal to the first preset water tank water temperature, control the first water pump to turn on, the second water pump to turn off, the third water pump to turn off, and the fourth water pump to turn off;

[0235] In the third anti-freezing mode, since the current water tank water temperature is too low, it may cause the buffer water tank 1 to freeze. At this time, the temperature in the solar collector 21 is even lower. Therefore, it is necessary to connect the buffer water tank 1 to the solar collector 21 to allow liquid to flow and avoid liquid freezing. At the same time, since the temperature in the kang body structure 3 is also low and heat cannot be output outward, the fourth water pump also needs to be turned off to prevent the kang body structure 3 from freezing.

[0236] K. Third water tank heat supplement mode

[0237] When the current water tank water temperature is greater than the first preset water tank water temperature and less than or equal to the second preset water tank water temperature, control the first water pump to turn on, the second water pump to turn off, the third water pump to turn off, and the fourth water pump to turn on;

[0238] In the third water tank heat supplement mode, the temperature of the solar collector 21 is the highest, while the temperature in the kang body structure 3 is the lowest. At this time, there is no risk of freezing in the buffer water tank 1, but due to the low temperature, heat cannot be supplied to the kang body structure 3. Therefore, heat is supplied from the solar collector 21 to the buffer water tank 1 to quickly increase the temperature in the buffer water tank 1.

[0239] L. Second linkage heating mode

[0240] When the water temperature of the current water tank is greater than the second preset water tank temperature, control the first water pump to turn on, the second water pump to turn on, the third water pump to turn off, and the fourth water pump to turn on.

[0241] In the second linked heating mode, at this time, the temperature in the buffer water tank 1 has reached the phase change temperature and can supply heat to the kang body structure 3. At the same time, since the temperature of the solar collector 21 is the highest, the three are interconnected, so that the high temperature is gradually transferred from the solar collector 21 to the kang body structure 3 and stored for subsequent use.

[0242] In the room temperature regulation system 100 provided by the present invention, it can be used in the summer refrigeration process. Based on this, the current working mode of the room temperature regulation system includes a refrigeration mode to facilitate reducing the indoor temperature in the summer for user use.

[0243] Specifically, step S20 includes:

[0244] S23. When the room temperature regulation system is in the refrigeration mode, obtain the current indoor temperature;

[0245] Among them, when refrigeration is required, first obtain the current indoor temperature and judge whether refrigeration is required at this time to cool down the overall temperature in the room temperature regulation system 100 to absorb the external heat and ensure that the indoor temperature remains comfortable.

[0246] S24. When the current indoor temperature is greater than or equal to the second preset indoor temperature, obtain the current energy supply temperature on the first energy supply water path and the current water tank temperature in the buffer water tank, and control the first water pump, the second water pump, the third water pump, and the fourth water pump according to the current energy supply temperature and the current water tank temperature;

[0247] Among them, when the current indoor temperature is greater than or equal to the second preset indoor temperature, it indicates that the indoor temperature is too high and refrigeration is required at this time. Therefore, it is necessary to judge how to cool down the kang body structure 3 according to the refrigeration capabilities of the solar collector 21 and the heat pump assembly in the energy supply device at this time.

[0248] S25. When the current indoor temperature is less than the second preset indoor temperature, obtain the current energy storage water temperature on the energy storage water path and the current water tank temperature in the buffer water tank, and control the first water pump, the second water pump, the third water pump, and the fourth water pump according to the current energy storage water temperature and the current water tank temperature.

[0249] Wherein, when the current indoor temperature is less than the second preset indoor temperature, at this time, the indoor environmental temperature has been maintained at a relatively low comfortable temperature. Therefore, the temperature on the kang body structure 3 can be obtained to determine whether to output cold energy outward.

[0250] In this embodiment, by judging the magnitude relationship between the current indoor temperature and the second preset indoor temperature, it is determined whether to cool the phase change energy storage module or whether the phase change energy storage module can cool outward. While ensuring the indoor environmental temperature, the phase change energy storage module can be made to cool outward, without the need to frequently turn on the heat pump assembly 22, reducing energy consumption and ensuring the comfort of the living environment.

[0251] Specifically, in this embodiment, step S24 includes:

[0252] M. Solar heat dissipation mode

[0253] S241. When the current energy supply temperature is less than the current water tank water temperature, control the first water pump to turn on, the second water pump to turn off, the third water pump to turn off, and the fourth water pump to turn on;

[0254] In the solar heat dissipation mode, at this time, the temperature in the solar collector 21 is less than that in the buffer water tank 1. Therefore, the buffer water tank 1 can be cooled by the solar collector 21, first reducing the temperature in the buffer water tank 1 to facilitate subsequent cooling of the kang body structure 3.

[0255] It should be noted that when there is no sunlight at night or the heating effect of sunlight is less than the heat dissipation effect in other weather conditions, the solar collector 21 can dissipate heat and cool the liquid inside it. At this time, the temperature in the solar collector 21 can be less than that in the buffer water tank 1.

[0256] N. Indoor cooling mode

[0257] S242. When the current energy supply temperature is greater than or equal to the current water tank water temperature, control the first water pump to turn off, the second water pump to turn on, the third water pump to turn on, and the fourth water pump to turn on.

[0258] In the indoor cooling mode, at this time, the solar collector 2 cannot cool the buffer water tank 1 either. And at this time, the indoor temperature needs to be cooled. At this time, control the heat pump assembly 22 to operate in the cooling mode to reduce the temperature in the buffer water tank 1. At the same time, further reduce the temperature in the kang body structure 3 to achieve a reduction in the indoor environmental temperature.

[0259] On the other hand, in this embodiment, step S25 includes:

[0260] S251. Determine whether the current energy storage water temperature exceeds the current water tank water temperature to obtain a third judgment result;

[0261] Among them, based on the third judgment result, determine whether the temperature in the kang body structure 3 can be reduced by the temperature of the buffer water tank 1 itself at this time.

[0262] S252. Determine whether the current energy supply temperature on the first energy supply water path exceeds the current water tank water temperature to obtain a fourth judgment result;

[0263] Among them, based on the fourth judgment result, determine whether the solar collector 21 can dissipate heat from the buffer water tank 1.

[0264] S253. Control the first water pump, the second water pump, the third water pump, and the fourth water pump according to the third judgment structure, the fourth judgment result, and the current water tank water temperature.

[0265] In this embodiment, after obtaining the third judgment structure and the fourth judgment result, the magnitude of the energy that needs to be input or can be output in the buffer water tank 1 at this time can be judged according to the current water tank water temperature, and then it is determined whether the solar collector 21 and the kang body structure 3 can be connected accordingly.

[0266] Specifically, when the third judgment result is that the current energy storage water temperature is greater than or equal to the current water tank water temperature, and the fourth judgment result is that the current energy supply temperature is less than the current water tank water temperature.

[0267] In the embodiment provided by the present invention, the temperature in the kang body structure 3 is higher than the temperature in the buffer water tank 1. At the same time, the temperature in the solar collector 21 is lower than the temperature in the buffer water tank 1. At this time, the temperature in the kang body structure 3 is the highest, and at the same time, the temperature in the solar collector 21 is the lowest, which means that at this time, the solar collector 21 is in a heat dissipation state at night, or in other environments with weak sunlight. The solar collector 21 can dissipate heat outward. At this time, it is necessary to ensure that the temperature of the kang body structure 3 is reduced.

[0268] Based on this, in step S253, the following two usage modes are included.

[0269] O. First linkage refrigeration mode

[0270] When the current water tank water temperature is less than the fourth preset water tank water temperature, control the first water pump to turn on, the second water pump to turn on, the third water pump to turn off, and the fourth water pump to turn on;

[0271] In the first linked refrigeration mode, the current water tank water temperature can deliver sufficient cooling capacity to the phase change energy storage module in the kang body structure 3 to lower the temperature in the kang body structure 3. At the same time, since the temperature of the solar collector 21 is lower, the solar collector 21 cools the buffer water tank 1 and the kang body structure 3 in sequence to cool the kang body structure 3 and store the cooling capacity in the kang body structure 3.

[0272] P. First water tank supplementary cooling mode

[0273] When the current water tank water temperature is greater than or equal to the fourth preset water tank water temperature, control the first water pump to turn on, the second water pump to turn off, the third water pump to turn off, and the fourth water pump to turn off.

[0274] In the first water tank supplementary cooling mode, the temperature in the buffer water tank 1 is relatively high and effective cooling of the kang body structure 3 cannot be achieved. At this time, the indoor temperature is qualified, so there is no need to urgently cool the kang body structure 3. Instead, by connecting the solar collector 21, rapid cooling of the buffer water tank 1 is achieved. At the same time, in this embodiment, since the temperature in the kang body structure 3 is too high to provide sufficient cooling capacity to the outside, control the fourth water pump to turn off and no longer absorb heat from the outside to avoid the temperature of the kang body structure 3 being too high and unable to be quickly reduced later.

[0275] On the other hand, when the third judgment result is that the current energy storage water temperature is greater than or equal to the current water tank water temperature, and the fourth judgment result is that the current energy supply temperature is greater than or equal to the current water tank water temperature;

[0276] In the embodiment provided by the present invention, at this time, the temperature in the buffer water tank 1 is lower than that in both the solar collector 21 and the kang body structure 3, indicating that at least at this moment the solar collector 21 will absorb heat from the outside. Therefore, it is necessary to exclude the solar collector 21 and only connect the buffer water tank 1 and the kang body structure 3 to control the temperature.

[0277] Based on this, in step S253, the following two usage modes are included.

[0278] Q. Water tank refrigeration mode

[0279] When the current water tank water temperature is less than the fourth preset water tank water temperature, control the first water pump to turn off, the second water pump to turn on, the third water pump to turn off, and the fourth water pump to turn on;

[0280] In the water tank refrigeration mode, the buffer water tank 1 is only connected to the kang body structure 3. Since the temperature in the buffer water tank 1 is lower, and at this time the temperature in the buffer water tank 1 can meet the condensation phase change temperature of the phase change energy storage module in the kang body structure 3, therefore, the buffer water tank 1 is used to refrigerate the kang body structure 3 and store the low temperature at this time for the user's use.

[0281] R, the second self-cooling mode

[0282] When the current water tank water temperature is greater than or equal to the fourth preset water tank water temperature, control the first water pump to close, the second water pump to close, the third water pump to close, and the fourth water pump to close.

[0283] In the second self-cooling mode, the temperature in the buffer water tank 1 cannot achieve the condensation phase change of the phase change energy storage module, so the cold energy cannot be stored in the kang body structure 3. At this time, the indoor temperature has met the user's needs. Therefore, all water pumps are turned off and heat circulation is no longer carried out to avoid affecting the indoor environmental temperature of the user.

[0284] On the other hand, when the third judgment result is that the current energy storage water temperature is less than the current water tank water temperature, and the fourth judgment result is that the current energy supply temperature is less than the current water tank water temperature;

[0285] In the embodiment provided by the present invention, the temperature in the solar collector 21 is the lowest, and the buffer water tank 1 and the kang body structure 3 can be cooled. Therefore, it is necessary to consider whether to control the temperature through the solar collector 21 and store the low temperature in the kang body structure 3.

[0286] It should be noted that the temperature in the solar collector 21 is the lowest at this time, indicating that at least at this moment the solar collector 21 is in a heat dissipation state, that is, the external light heating effect is less than the heat dissipation effect.

[0287] Based on this, in step S253, the following two usage modes are also included.

[0288] S, the second linkage refrigeration mode

[0289] When the current water tank water temperature is less than the fourth preset water tank water temperature, control the first water pump to open, the second water pump to open, the third water pump to close, and the fourth water pump to open;

[0290] In the second linked refrigeration mode, the current water tank water temperature is lower than the fourth preset water tank water temperature. At this time, the temperature in the buffer water tank 1 is already lower than the condensation phase change temperature of the phase change material. Therefore, the solar collector 21 - the buffer water tank 1 - the kang body structure 3 are interconnected, so that the low-temperature liquid in the supercooled solar collector 21 finally transfers the low temperature to the kang body structure 3, realizing the storage of low temperature for subsequent use when low temperature is needed, without the need to turn on the heat pump assembly for active refrigeration.

[0291] T. Second water tank cold supplement mode

[0292] When the current water tank water temperature is greater than or equal to the fourth preset water tank water temperature, control the first water pump to turn on, the second water pump to turn off, the third water pump to turn off, and the fourth water pump to turn on.

[0293] In the second water tank cold supplement mode, the temperature in the buffer water tank 1 is too high to realize the condensation phase change of the phase change material in the kang body structure 3. Therefore, it is necessary to cool the buffer water tank 1 through the solar collector 21 so that it can deliver cold to the kang body structure 3. In the embodiment, turn on the first water pump to enable heat exchange between the solar collector 21 and the buffer water tank 1 and reduce the temperature in the buffer water tank 1.

[0294] On the other hand, when the third judgment result is that the current energy storage water temperature is lower than the current water tank water temperature, and the fourth judgment result includes that the current energy supply temperature is greater than or equal to the current water tank water temperature;

[0295] In the embodiment provided by the present invention, the current energy storage water temperature is lower than the current water tank water temperature. At this time, the temperature in the kang body structure 3 is the lowest. Therefore, the high temperature in the solar collector 21 and the buffer water tank 1 is prevented from affecting the temperature in the kang body structure 3.

[0296] Based on this, in step S253, it further includes:

[0297] U. Third self-cooling mode

[0298] Control the first water pump to turn off, the second water pump to turn off, the third water pump to turn off, and the fourth water pump to turn on.

[0299] In the third self-cooling mode, turn off the first water pump, the second water pump, and the third water pump, so that the kang body structure 3 does not have heat interaction with other components, and only provides cold to the room and water-using components, extending the use time of the cold in the kang body structure 3 and keeping the refrigeration effect for a long time, thereby controlling the room temperature and preventing the room temperature from rising too fast, resulting in the need to turn on the heat pump assembly 22.

[0300] Based on the above refrigeration and heating modes, the control method for the room temperature adjustment includes the following modes for the first water pump, the second water pump, the third water pump, and the fourth water pump:
