[0002] Thermal storage intelligent temperature control systems heat and store heat during off-peak hours, saving electricity and reducing heating operating costs. As a result, various non-coal heating equipment is gradually penetrating various electric heating fields.

[0003] Chinese Patent Publication No. CN110068041A discloses a thermal storage intelligent temperature regulation system and a control method for the intelligent temperature regulation system. The thermal storage intelligent temperature regulation system includes a system shell, a first phase change thermal storage layer, and a second phase change thermal storage layer. The first and second phase change thermal storage layers are stacked within the system shell. The phase change temperature of the first phase change thermal storage layer is higher than that of the second phase change thermal storage layer. A heating element is provided in the first phase change thermal storage layer. The wall on the system shell opposite the second phase change thermal storage layer is called the front wall. An air duct is formed between the front wall and the second phase change thermal storage layer, and the system shell has an air inlet and an air outlet connected to the air duct. Therefore, the aforementioned thermal storage intelligent temperature regulation system and control method have the following problems: poor thermal storage capacity, inability to adjust the heating mode according to different apartment types, high energy consumption, unstable heating, and low heating efficiency. Summary of the Invention

[0004] To address these issues, the present invention provides an intelligent temperature control system based on indoor environmental parameter monitoring, which solves the problems of poor heat storage capacity, inability to adjust heating mode according to different house types, high energy consumption, unstable heating, and low heating efficiency in existing intelligent temperature control systems.

[0005] To achieve the above objectives, the present invention provides an intelligent temperature control system based on indoor environmental parameter monitoring, characterized in that it comprises:

[0006] The outer shell has a rock wool insulation layer on its inner surface to prevent heat loss from the shell; the top of the outer shell has an outlet for hot air output, and the bottom of the side wall of the outer shell has an air inlet with a fan at the air inlet to drive the air flow in the intelligent temperature regulation system.

[0007] The bottom support, which is connected to the outer shell by a pivot, is used to support the outer shell and drive it to rotate;

[0008] The display controller is installed on the surface of the housing and is used to automatically determine the initial rotation speed of the housing, the initial speed of the fan and the initial power of the heating element according to the room area, and to determine whether to adjust the corresponding control parameters to the corresponding values ​​according to the minimum distance between the air outlet and the wall.

[0009] The heating unit, located inside the outer casing, exchanges heat through internal heat-conducting oil and phase change material to enable the intelligent temperature control system to output heat to the room.

[0010] Furthermore, the heating unit structure uses heat-conducting oil to encapsulate the heat storage material structure, including:

[0011] Several encapsulated inner liner are arranged side by side inside the outer shell, and each encapsulated inner liner has several fixed brackets and several electric heaters at its bottom to convert the electrical energy of the electric heaters into heat energy.

[0012] Several heat storage material boxes are respectively disposed inside the corresponding encapsulation liner and connected to the encapsulation liner through the corresponding fixing bracket. The heat storage material boxes are filled with phase change material to absorb and store the heat generated by the electric heater. The phase change material is either an inorganic phase change material or an organic phase change material.

[0013] Heat-conducting oil is disposed between each of the encapsulated inner liner and the corresponding heat storage material box to uniformly transfer the heat stored in the heat storage material box to the surface of the encapsulated inner liner.

[0014] Furthermore, the display controller includes a first preset area S1, a second preset area S2, a house characteristic parameter K, a standard parameter C, a first area adjustment coefficient α1, and a second area adjustment coefficient α2, wherein 0 < S1 < S2, 0 < α1 < 1 < α2 < 2, and 0 < C. The outer casing rotation speed is set to V = K × V0, the fan speed to R = R0 / K, and the heating element power to Q = Q0 / K. When the intelligent temperature control system is activated, the display controller compares the pre-input and recorded heated house area S with S1 and S2 to determine the initial house characteristic parameter K0. Based on K0, it sequentially calculates the initial rotation speed V of the outer casing, the initial fan speed to R, and the initial power Q of the heating element, setting V = K0 × V0, R = R0 / K0, and Q = Q0 / K0, where V0 is the reference outer casing rotation speed, R0 is the reference fan speed, and Q0 is the reference heating element power.

[0015] If S≤S1, the display controller determines K0=α2×C;

[0016] If S1 < S ≤ S2, the display controller determines that K0 = C;

[0017] If S2 < S, the display controller determines that K0 = α1 × C.

[0018] Furthermore, the display controller is equipped with a distance module for measuring the distance L from the external air vent to the wall it faces, and the display controller has a first preset difference value ΔK. a The parameters are: second preset difference ΔKb, reference distance L0, first difference adjustment coefficient β1, and second difference adjustment coefficient β2, where ΔKb is the second preset difference ΔKb. a <0<△Kb, 0<β1<β2, the display controller calculates the indoor characteristic parameter K1 of the heat output of the intelligent temperature control system when the intelligent temperature control coefficient runs for A1 time. K1 is set to (L0 / L)×C. After completing this calculation, and every t1 time the intelligent temperature control coefficient runs, the display controller recalculates the indoor characteristic parameter of the heat output of the intelligent temperature control system. After the intelligent temperature control system runs for A1+(i-1)×t1 time, i is set to 2, 3…n, where n is the total number of times the display controller calculates the indoor characteristic parameter. The display controller records the indoor characteristic parameter of the heat output flow during the last running cycle of the intelligent temperature control system as Ki. Each time the display controller completes the calculation of Ki, it calculates the difference △Ki between Ki and the previous measured value Ki-1, and compares △Ki with △Kb. a Compare with ΔKb to determine whether C needs adjustment, and set ΔKi = Ki - Ki-1.

[0019] If △Ki≤△K a The display controller determines that the standard parameter C is adjusted using β2, and the adjusted standard parameter C is denoted as Ca. Ca is set to C × β2.

[0020] If △K a If △Ki ≤ △Kb, the display controller determines that no adjustment of the standard parameter C is required;

[0021] If △Kb<△Ki, the display controller determines to use β1 to adjust the standard parameter C, and the adjusted standard parameter C is denoted as Ca, and Ca=C×β1 is set.

[0022] Furthermore, the display controller is equipped with a first preset distance L1, a second preset distance L2, a preset percentage P1, a first adjustment range c1, and a second adjustment range c2, wherein 0 < c1 < 1 < c2. The display controller is equipped with an infrared detector to detect the number of people N in the environment where the intelligent temperature control system is located and the distance Li between each person and the intelligent temperature control system, i = 1, 2, 3...N, where i represents the i-th person. When the intelligent temperature control system operates for a duration A1, the display controller sequentially counts the number of people N1 that meet the adjustment condition Li ≤ L1, the number of people N2 that meet the condition L1 < Li ≤ L2, and the number of people N3 that meet the condition Li > L2, and calculates the percentage P of people that meet the condition L1 < Li ≤ L2. P is set to N2 / N. The display controller compares P with P1 to determine whether to adjust the standard parameter C.

[0023] If P≤P1, the display controller determines to compare N1 and N3 and further adjust Ki according to the comparison result. If N1≥N3, the display controller uses c1 to adjust the standard parameter C. The adjusted C is recorded as C', and C' = C × c1 is set.

[0024] If N1 < N3, the display controller uses c2 to adjust the standard parameter C, and the adjusted C is recorded as C'. Set C' = C × c2.

[0025] If P > P1, the display controller determines that there is no need to adjust the standard parameter C.

[0026] Furthermore, the display controller has a first preset time Y1 and a second preset time Y2, where 0 < Y1 < Y2. When the intelligent temperature control system is running, if the number of people detected by the infrared detector N = 0, the display controller records the duration Y during which no people are detected and compares Y with Y1 and Y2 to determine whether to automatically shut down the intelligent temperature control system.

[0027] If Y≤Y1, the display controller determines that the intelligent temperature control system is operating normally;

[0028] If Y1 < Y ​​≤ Y2, the display controller determines that the user has left and plays a prompt signal to remind the user to turn off the intelligent temperature control system;

[0029] If Y2 < Y, the display controller determines that the user has been away for too long and automatically shuts down the intelligent temperature control system.

[0030] Furthermore, the display controller is externally connected to an indoor temperature sensor to monitor the indoor temperature. The display controller has a first preset temperature difference ΔT1, a second preset temperature difference ΔT2, and a temperature difference detection period Tz, where 0 < ΔT1 < ΔT2. When the intelligent temperature control system operates for a duration A2, the display controller records the indoor temperature Ti every t2 seconds, i = 1, 2, 3...n. After each temperature difference detection period, the display controller extracts the highest indoor temperature Tmax and the lowest indoor temperature Tmin recorded in that period and calculates their difference ΔT, which is set to ΔT = 1Tmax - Tmin1. After the calculation, the display controller compares ΔT with ΔT1 and ΔT2 respectively to determine whether the indoor temperature is stable.

[0031] If △T≤△T1, the display controller determines that the indoor temperature is stable;

[0032] If △T1<△T≤△T2, the display controller initially determines that there is a temperature difference in the room and further determines whether to adjust the standard parameter C based on Tmin;

[0033] If △T2 < △T, the display controller determines that there is a significant temperature difference in the room and displays inspection and maintenance information to remind the user to troubleshoot the intelligent temperature control system.

[0034] Furthermore, the display controller is provided with a first minimum temperature standard Tmin1, a second minimum temperature standard Tmin2, a third adjustment range c3, and a fourth adjustment range c4, wherein Tmin1 < Tmin2, 0 < c3 < c4. When the display controller determines that there is a temperature difference in the room and further determines whether to adjust the standard parameter C based on Tmin, the display controller compares Tmin with Tmin1 and Tmin2 respectively to determine whether to adjust the standard parameter C.

[0035] If Tmin≤Tmin1, the display controller displays a prompt message to remind the user to check if there is any cold air from outside flowing into the room;

[0036] If Tmin1 < Tmin ≤ Tmin2, the display controller determines to use c4 to adjust the standard parameter C, and the adjusted C is denoted as C”. Set C” = C × c4;

[0037] If Tmin2 < Tmin, the display controller determines to use c3 to adjust the standard parameter C, and the adjusted C is denoted as C”. C” is set to C × c3.

[0038] Furthermore, the display controller is provided with a first preset device temperature Tw1, a second preset device temperature Tw2, and a power adjustment coefficient γ, wherein 0 < Tw1 < Tw2, 0 < γ. An internal device temperature sensor is installed inside the encapsulation liner to detect the temperature Tw within the intelligent temperature control system. When the intelligent temperature control system operates for A3s, the display controller compares Tw with both Tw1 and Tw2 to determine whether to adjust the electric heater.

[0039] If Tw≤Tw1, the display controller determines that Q is adjusted using γ, and the adjusted Q is denoted as Q', Q'=Q×γ;

[0040] If Tw1 < Tw ≤ Tw2, the display controller determines that the temperature in the intelligent temperature regulation system is normal and there is no need to adjust Q;

[0041] If Tw2 < Tw, the display controller determines to use the low power mode, that is, only one electric heater is running at the bottom of each heat storage material box;

[0042] The display controller has a maximum temperature standard Tmax1. When Tmax > Tmax1, the display controller controls the fan to stop rotating. The indoor temperature sensor is connected to the display controller via remote communication.

[0043] Furthermore, the heating unit structure can also use heat storage material to encapsulate the heat transfer oil structure, including:

[0044] An inner liner is provided inside the outer shell, and several electric heating boxes are provided at the bottom of the inner liner, with electric heaters provided inside the electric heating boxes;

[0045] Heat transfer oil is disposed between the electric heating box and the electric heater to transfer heat from the electric heater to the surface of the electric heating box;

[0046] A phase change material is disposed between the inner packaging liner and the electric heating box to transfer heat from the electric heating box to the surface of the inner packaging liner;

[0047] Fins are disposed on the surface of the electric heating box to transfer heat from the electric heating box to the phase change material.

[0048] Furthermore, the display controller can establish a communication connection with the user's mobile phone so that the user can control the intelligent temperature regulation system through the mobile phone.

[0049] Furthermore, the indoor temperature sensor and the display controller are connected via remote communication.

[0050] Compared with the prior art, the beneficial effects of the present invention are that the intelligent temperature regulation system of the present invention can rotate, and the intelligent temperature regulation system can provide different heating intensities according to the size of the heated house area, thereby improving the power efficiency of heating, and when the indoor temperature reaches a certain level, the fan stops rotating, effectively saving energy.

[0051] Furthermore, the display controller is equipped with house characteristic parameters to provide different heating intensities according to the size of the room being heated, ensuring heating while improving the heating speed, and further improving the heating efficiency of the present invention.

[0052] Furthermore, the display controller is equipped with a first preset difference, a second preset difference, a reference distance, a first difference adjustment coefficient, and a second difference adjustment coefficient, so that when the intelligent temperature control system switches from heating a small space to a large space, it can adjust its heating intensity in a timely manner, ensuring the heating effect while further improving the heating efficiency of the present invention.

[0054] Furthermore, the display controller is equipped with a first preset time and a second preset time. If no one is detected in the room for an extended period of time, the intelligent temperature control system will automatically shut down, thus avoiding energy consumption and safety hazards caused by the user forgetting to turn off the intelligent temperature control system.

[0055] Furthermore, the display controller is equipped with a first preset temperature difference, a second preset temperature difference, and a temperature difference detection cycle. Each cycle determines whether the room temperature is stable, avoiding the problem of poor heating effect caused by the failure of the intelligent temperature regulation system or the house being closed. While ensuring the heating effect, it further improves the heating efficiency of the present invention.

[0056] Furthermore, the present invention provides a second preset equipment temperature. When the temperature of the electric heater reaches the second preset equipment temperature, the display controller determines to use a low-power mode, that is, only one electric heater is running at the bottom of each heat storage material box, which effectively saves energy consumption, ensures the heating effect, and further improves the heating efficiency of the present invention.

It is used to automatically determine the initial rotation speed of the housing 1, the initial fan speed 9, and the initial heating tube power according to the room area, determine whether to adjust the control parameters according to the distance from the air outlet 6 to the wall it faces, and determine whether the room temperature is stable and make corresponding adjustments according to the room temperature change. Users can actively adjust the rotation speed of the housing 1, the fan speed 9, and the heating tube power through the display controller 12.

[0082] Specifically, the heating unit structure uses heat-conducting oil to encapsulate the heat storage material structure, including:

[0083] Several inner liner 2 are disposed inside the outer shell 1, and several fixed brackets 11 and several electric heaters 5 are provided at the bottom of the inner liner 2 to generate heat;

[0084] Several heat storage material boxes 3 are disposed inside the encapsulated inner liner 2 and connected to the encapsulated inner liner 2 through a fixed bracket 11. The heat storage material boxes 3 contain inorganic or organic phase change materials 10 to absorb and store the heat generated by the electric heater 5.

When the intelligent temperature control system is started, the display controller 12 compares the pre-input recorded heated house area S with S1 and S2 respectively to determine the initial house characteristic parameter K0. Based on K0, the initial rotation speed V of the outer shell 1, the initial speed R of the fan 9, and the initial power Q of the heating element are calculated sequentially. V = K0 × V0, R = R0 / K0, Q = Q0 / K0, where V0 is the reference rotation speed of the outer shell 1, R0 is the reference speed of the fan 9, and Q0 is the reference heating element power, where V0 = 10° / s, R0 = 15 rpm, and Q0 = 1500W.

[0087] If S≤S1, the display controller 12 determines that K0=α2×C;

[0088] If S1 < S ≤ S2, the display controller 12 determines that K0 = C;

[0089] If S2 < S, the display controller 12 determines that K0 = α1 × C.

[0090] Specifically, the display controller 12 is equipped with a distance module for measuring the distance L from the external air vent 6 to the wall it faces, and the display controller 12 is equipped with a first preset difference value ΔK. a The parameters are: second preset difference ΔKb, reference distance L0, first difference adjustment coefficient β1, and second difference adjustment coefficient β2, where ΔKb is the second preset difference ΔKb. a <0<△Kb, 0<β1<β2, the display controller 12 calculates the indoor characteristic parameter K1 of the heat output of the intelligent temperature control system when the intelligent temperature control coefficient runs for A1 time. K1 is set to (L0 / L)×C. After completing this calculation, and every t1 time the intelligent temperature control coefficient runs, the display controller 12 recalculates the indoor characteristic parameter of the heat output of the intelligent temperature control system. After the intelligent temperature control system runs for A1+(i-1)×t1 time, i is set to 2, 3…n, where n is the total number of times the display controller 12 calculates the indoor characteristic parameter. The display controller 12 records the indoor characteristic parameter of the heat output flow during the last running cycle of the intelligent temperature control system as Ki. Each time the display controller 12 completes the calculation of Ki, it calculates the difference △Ki between Ki and the previous measured value Ki-1, and compares △Ki with △Kb. a Compare with ΔKb to determine whether C needs adjustment, and set ΔKi = Ki - Ki-1.

[0093] If △Kb < △Ki, the display controller 12 determines to use β1 to adjust the standard parameter C, and the adjusted standard parameter C is denoted as Ca, and Ca is set to C × β1.

[0094] Specifically, the display controller 12 has a first preset distance L1, a second preset distance L2, a preset percentage P1, a first adjustment range c1, and a second adjustment range c2, where L1 = 2m, L2 = 7m, c1 = 0.8, c2 = 1.2, and P1 = 60%. The display controller 12 is equipped with an infrared detector to detect the number of people N in the environment where the intelligent temperature control system is located and the distance Li between each person and the intelligent temperature control system, i = 1, 2, 3...N, where i represents the i-th person.

[0098] Specifically, the display controller 12 has a first preset time Y1 and a second preset time Y2, where Y1 = 10 min and Y2 = 20 min. When the intelligent temperature control system is running, if the number of people N detected by the infrared detector is 0, the display controller 12 records the duration Y during which no people are detected and compares Y with Y1 and Y2 to determine whether to automatically shut down the intelligent temperature control system.

[0099] If Y≤Y1, the display controller 12 determines that the intelligent temperature control system is operating normally;

[0100] If Y1 < Y ​​≤ Y2, the display controller 12 determines that the user has left and plays a prompt signal to remind the user to turn off the intelligent temperature control system.

[0101] If Y2 < Y, the display controller 12 determines that the user has been away for too long and automatically shuts down the intelligent temperature control system.

The display controller 12 has a first preset temperature difference ΔT1, a second preset temperature difference ΔT2, and a temperature difference detection period Tz, where ΔT1 = 5℃ and ΔT2 = 10℃. When the intelligent temperature control system operates for 600 seconds, the display controller 12 records the indoor temperature Ti every t2 seconds, i = 1, 2, 3...n. After each temperature difference detection period, the display controller 12 extracts the highest indoor temperature Tmax and the lowest indoor temperature Tmin recorded in that period and calculates their difference ΔT, which is set as ΔT = 1Tmax - Tmin1. After the calculation, the display controller 12 compares ΔT with ΔT1 and ΔT2 respectively to determine whether the indoor temperature is stable.

[0103] If △T≤△T1, the display controller 12 determines that the indoor temperature is stable;

[0104] If △T1<△T≤△T2, the display controller 12 initially determines that there is a temperature difference in the room and further determines whether to adjust the standard parameter C based on Tmin;

[0105] If △T2 < △T, the display controller 12 determines that there is a significant temperature difference in the room and displays inspection and maintenance information to remind the user to troubleshoot the intelligent temperature control system.
