Description

Technical Field

[0001] The invention relates to an intelligent linkage system of a solar panel and a heat pump. Background Art

[0002] Currently, solar panels that collect solar energy and convert it into heat for indoor heating have penetrated into many households and are widely used in areas with abundant sunshine.

[0003] However, current household solar panels still fail to ensure automatic and effective monitoring of key components in solar energy collection systems (such as heat pumps), which can easily lead to serious aging of these key components and easily affect the service life of the entire solar heating system. Summary of the Invention

[0004] The present invention provides an intelligent linkage system of solar panels and heat pumps, which effectively overcomes the above-mentioned defects in the prior art.

[0005] Specifically, the present invention provides an intelligent linkage system of solar panels and heat pumps for solar heating in a house. Solar panels are arranged on the roof of the main body of the house, and an air intake space is formed between the roof and the solar panels. The air in the air intake space is heated to form hot air, and the hot air is sent to the air source heat pump through the air supply device, so that the air source heat pump can heat the indoor equipment. The system includes a temperature sensor arranged at the air source heat pump for sensing the heat source temperature difference ΔT, a power sensor arranged at the outlet of the air source heat pump for sensing the output power P, a wind speed sensor arranged at the air supply device for sensing the air flow rate V of the hot air transported by the air supply device to the air source heat pump, and a central processing unit. The central processing unit includes a determination module and a command module. The heat source temperature difference ΔT, output power P, and air flow rate V sensed at each moment are transmitted to the determination module in real time and follow the following logarithmic formula:

[0006] ,

[0007] Where COP is the coefficient of performance of the air source heat pump, and α is a constant.

[0008] At the initial moment, the determination module puts the initial heat source temperature difference ΔT0, the initial output power P0, and the initial air flow rate V0 into the above logarithmic formula to calculate the logarithmic value ln COP0 of the initial coefficient of performance COP0. If ln COP0 falls outside the interval [MinLnCOP, MaxLnCOP], the initial air flow rate V0 is reversely assigned an initial step value Lv0 to form an air flow rate adjustment value V1. The central processing unit then sends the adjustment value V1 to the air supply device to enable the air supply device to deliver hot air at the flow rate of the adjustment value V1, resulting in the formation of an updated heat source temperature difference ΔT1 and output power P1. The determination module calculates the first-level vector distance L1 according to the first distance formula:

[0009] ,

[0010] Set the distance threshold MaxL. If it is determined that L1>MaxL, the judgment module will halve the initial step value Lv0 to the first-level step value Lv1=Lv0 / 2 to form the air flow rate adjustment value V2. The central processing unit then sends the adjustment value V2 to the air supply device to enable the air supply device to deliver hot air at the flow rate of the adjustment value V2, resulting in an updated heat source temperature difference ΔT2 and output power P2. The judgment module calculates the second-level vector distance L2. If it is determined that L2>MaxL, then the same process is repeated until the k-th level vector distance Lk≤MaxL is calculated, where k is an integer and k≥2. At this time, the k-th level step value is Lvk= Lv0 / 2 k ,Then, the command module remotely issues a command to the air supply device, instructing the air supply device to adjust the air flow rate in reverse according to the k-th step value Lvk, ensuring that the natural logarithm of the final COP is within the interval [MinLnCOP, MaxLnCOP].

[0011] Preferably, the “reversely assigning an initial step value Lv0 to the initial air flow rate V0 to form the air flow rate adjustment value V1” includes: if ln COP0 is less than MinLnCOP, then the natural logarithm of the adjustment value V1 is adjusted to lnV1=lnV0+Lv0, that is, V1=V0*e Lv0 On the contrary, if the current value ln COP0 is greater than MaxLnCOP, the natural logarithm of the adjustment value V1 is adjusted to lnV1=lnV0-Lv0, that is, V1=V0 / e Lv0 .

[0012] Preferably, “the determination module reduces the initial step value Lv0 by half to Lv1=Lv0 / 2 to form the air flow rate adjustment value V2” includes: if ln COP0 is less than MinLnCOP, then the adjustment value V2 is adjusted to lnV2=lnV0+Lv1=lnV0+Lv0 / 2, that is, V2=V0*e Lv1= V0*e Lv0 / 2 Conversely, if ln COP0 is greater than the maximum value MaxLnCOP of the interval, the adjustment value V2 is adjusted to lnV2 = lnV0 - Lv1 = lnV0 - Lv0 / 2, that is, V2 = V0 / e Lv0 / 2 .

[0013] Preferably, "the determination module calculates the second-level vector distance L2" includes: the determination module calculates the second-level vector distance L2 according to the second distance formula:

[0014] .

[0015] Preferably, "until the k-level vector distance Lk is calculated" includes: on the basis of the calculation of the first-level vector distance and the second-level vector distance, and so on until the k-level vector distance Lk is calculated:

[0016] ,

[0017] Finally, if Lk ≤ MaxL is determined, the calculated k-level step value is Lvk = Lv0 / 2 k .

[0018] Preferably, the instruction issued by the command module to the air supply device remotely includes: if ln COP0 < MinLnCOP, the command module requires the air supply device to increase the initial air flow rate V0 to V0 + V0 / e Lvk , if ln COP < MinLnCOP still exists after the increase, then issue another instruction to increase the initial air flow rate to V0 + 2*V0 / e Lvk , then judge the size relationship between the adjusted coefficient of performance COP and MinLnCOP, and so on until the initial air flow rate V0 is increased to V0 + n*V0 / e Lvk , where n is an integer and n ≥ 2, and at this time the natural logarithm value of the final coefficient of performance is within the interval [MinLnCOP, MaxLnCOP].

[0019] Preferably, the instruction further issued by the command module to the air supply device remotely includes: if ln COP0 > MaxLnCOP, the command module requires the air supply device to decrease the initial air flow rate V0 to V0 - V0 / e Lvk , if the coefficient of performance ln COP > MaxLnCOP after the decrease, then issue another instruction to decrease the initial air flow rate to V0 - 2*V'0 / e Lvk , then judge the size relationship between the adjusted coefficient of performance COP and MaxLnCOP, and so on until the initial air flow rate V0 is decreased to V0 - n*V0 / e Lvk, where n is an integer and n≥2, so that the natural logarithm of the final performance coefficient is within the interval [MinLnCOP, MaxLnCOP].

[0020] In the process of solar heating, the intelligent linkage system of solar panels and heat pumps provided by the present invention first effectively adjusts the three parameters of output power, air flow rate, and heat source temperature difference based on the relationship between the solar panels inside and outside the house, the air supply equipment, and the air source heat pump. It determines the magnitude of the air flow rate that needs to be adjusted when the performance coefficient of the heat pump exceeds the rated range, and adjusts the air flow rate based on this magnitude, thereby ensuring that the performance coefficient of the heat pump is adjusted by reasonably adjusting the air flow rate within a controllable range, thereby ensuring the normal operation of the entire solar energy system.

Obviously, the technical solutions described in conjunction with the drawings are only some embodiments of the present invention. For ordinary technicians in this field, other embodiments and their drawings can be obtained based on the embodiments shown in these drawings without paying any creative work.

[0022] Figure 1 The figure roughly shows the actual application scenario of the intelligent linkage system of solar panels and heat pumps according to the present invention.

[0023] Figure 2 A diagram showing the interaction between the central processing unit and various sensors in the system according to the present invention is shown. DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments described in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present invention provides an intelligent linkage system of a solar panel and a heat pump, which is used for regulating indoor solar heating.

[0026] Figure 1 The figure roughly shows the actual application scenario of the intelligent linkage system of solar panels and heat pumps according to the present invention.

[0027] like Figure 1As shown, a solar panel 3 is installed on the roof 2 of the main body of the house 1, thereby forming an air intake space 4 between the roof 2 and the solar panel 3. As the solar panel 3 absorbs solar energy and forms heat, the air in the air intake space 4 is heated to form hot air. The hot air is delivered to the air source heat pump 6 through the air supply device 5, so that the air source heat pump 6 can heat the indoor equipment, thereby ultimately converting the solar energy from the solar panel 3 into thermal energy to heat the indoor equipment. The indoor equipment may be, for example, a water tank, which can be heated to boil water, or a cooking device, which can be heated to cook dishes, and so on.

[0028] In the entire system, the solar panels 3 are often already known products on the market, so there is little room for improvement. The system provided by the present invention focuses on the interactive coordination and adjustment between the air supply device 5 and the air source heat pump 6.

[0029] The heat input power input to the air source heat pump 6 can be roughly summarized as the following formula 1:

[0030] ,

[0031] In the above formula, Q is the heat power input to the air source heat pump 6, V is the air flow rate of the hot air delivered by the air supply device 5 to the air source heat pump 6, ΔT is the heat source temperature difference, that is, the temperature difference of the heat pump 6 itself relative to the high-temperature hot gas, and α is a constant value.

[0032] On this basis, the following formula 2 can be applied to calculate the output power of the air source heat pump 6:

[0033] ,

[0034] Where P is the output power of the air source heat pump 6, and COP is the coefficient of performance of the air source heat pump. It should be noted that the coefficient of performance (COP) here needs to be monitored in real time and should not be too large or too small. If the COP value is too large, it indicates that the efficiency of the air source heat pump 6 is too low, while if the COP value is too small, it will lead to the opposite effect, which may cause the heat pump to generate loud noise and shorten its service life.

[0035] In other words, the COP must be maintained within an appropriate range during overall system operation. While the above formula may seem simple, in actual operation, the heat source temperature difference ΔT affects the COP. A larger ΔT generally results in a higher COP. Air velocity V can also affect the COP, with a higher V generally increasing the COP.

[0036] In practice, the COP (Coefficient of Performance) often needs to be controlled within a range of 2.5 to 4. In some applications requiring advanced testing, the COP requirement is even more stringent, perhaps within the range of 3.30 to 3.35. The following details how to effectively control the COP of a heat pump using the system provided by the present invention.

[0037] As mentioned above, the most critical variable is the air flow rate V of the hot air delivered by the air supply device 5 to the air source heat pump 6. However, in the above formula, the change of the variable V will affect the entire system, and in the multiplication and division process of the above formula, the various related variables V, ΔT, COP, and P constrain each other. Therefore, hasty adjustment of the variable V may lead to uncontrolled adjustment of the COP, thereby causing the performance coefficient COP to instantly exceed the predetermined required range (such as the smaller range of 3.30 to 3.35 mentioned above).

[0038] To this end, the system provided by the present invention takes the natural logarithm of the above formula to form the following formula 3:

[0039] ,

[0040] Note that in the natural logarithm formula above, the variables V, ΔT, COP, P, and the quantitative parameter α are dimensionless. For example, if the air flow rate V is in cubic meters per hour, then if the air flow rate is 500 cubic meters per hour, simply substitute "500" into the natural logarithm formula above.

[0041] To this end, the system provided by the present invention is provided with a temperature sensor at the air source heat pump 6 for sensing the heat source temperature difference ΔT, and a power sensor is provided at the output of the air source heat pump 6 for sensing the output power P (it should be noted here that the output power P can actually be comprehensively sensed by sensing the current and voltage inside the heat pump 6, but for the sake of brevity in this article, the internal structure of the heat pump 6 is not introduced in detail), and a wind speed sensor is provided at the air supply device 5 for sensing the air flow rate V of the hot air delivered by the air supply device 5 to the air source heat pump 6. The sensed parameters ΔT, P, and V are all remotely transmitted to the central processing unit in real time, and the central processing unit determines whether and how to adjust the air flow rate V based on whether the COP exceeds the interval range.

[0042] The following will focus on the central processing unit's adjustment of air flow rate. Figure 2 A diagram showing the interaction between the central processing unit and various sensors in the system according to the present invention is shown.

[0043] As mentioned above, the coefficient of performance (COP) must be constrained within a specific range. Therefore, its natural logarithm, lnCOP, must also be constrained within a specific range, namely, within the interval [MinLnCOP, MaxLnCOP]. Therefore, the decision module in the central processing unit first inputs the currently known parameter values ​​ΔT0, P0, and V0, as well as the quantitative value α, into Equation 3 to calculate the current value of lnCOP0.

[0044] Next, the determination module determines whether the current value ln COP0 falls within the interval [MinLnCOP, MaxLnCOP]. If the current value is not within the interval, that is, if it is less than the interval minimum value MinLnCOP or greater than the interval maximum value MaxLnCOP, the determination module issues an adjustment instruction to the adjustment unit within the central processing unit to adjust the current air flow rate V0, more specifically, the natural logarithm value ln V0 of the air flow rate.

[0045] The adjustment unit first reversely assigns an air flow rate step value Lv0 to the current natural logarithm value lnV0 to form an updated natural logarithm value lnV1. The so-called "reverse assignment" means that if the current value ln COP0 is less than MinLnCOP, the adjustment value V1 needs to be adjusted to a higher value, lnV1 = lnV0 + Lv0, that is, V1 = V0 * e Lv0 On the contrary, if the current value ln COP0 is greater than the interval maximum value MaxLnCOP, the adjustment value V1 needs to be adjusted to a lower value, lnV1=lnV0-Lv0, that is, V1=V0 / e Lv0 .

[0046] Subsequently, the central processing unit sends the adjustment value V1 to the air supply device 5, and the air supply device 5 adjusts the air flow rate from V0 to V1 accordingly, thereby causing the overall changes in the parameters of the solar heating system. The temperature sensor senses the updated heat source temperature difference ΔT1, and the power sensor senses the updated output power P1.

[0047] Subsequently, the updated heat source temperature difference ΔT1 and output power P1 are transmitted back to the central processing unit. The determination module combines the adjusted air flow rate V1 and the updated heat source temperature difference ΔT1 and output power P1 to calculate the vector distance L1 between the parameters before the update. The calculation formula is as follows:

[0048] ,

[0049] A distance threshold, MaxL, is set. If L1 > MaxL, the adjustment of the air flow rate from V0 to V1 is determined to be uncontrollable. Therefore, the air flow rate value is updated to V2, and the original step length, Lv0, is halved to Lv1, i.e., Lv1 = Lv0 / 2. The adjustment unit inversely assigns an air flow rate step length, Lv1, to the natural logarithm value, lnV0, of the current air flow rate to form an updated natural logarithm value, lnV2.

[0050] If the current value ln COP0 is less than MinLnCOP, the adjustment value V2 needs to be adjusted to a higher value, lnV2=lnV0+Lv1, that is, V2=V0*e Lv1 On the contrary, if the current value ln COP0 is greater than the interval maximum value MaxLnCOP, the adjustment value V2 needs to be adjusted to a lower value, lnV2=lnV0-Lv1, that is, V2=V0 / e Lv1 .

[0051] Subsequently, the central processing unit sends the adjustment value V2 to the air supply device 5, and the air supply device 5 adjusts the air flow rate from V1 to V2 accordingly, thereby causing the overall changes in the parameters of the solar heating system. The temperature sensor senses the updated heat source temperature difference ΔT2, and the power sensor senses the updated output power P2.

[0052] The adjustment values ​​ΔT2, P2, and V2 are transmitted back to the central processing unit, and the decision module calculates the vector distance L2 between these parameters and the parameters before the update. The calculation formula is as follows:

[0053] ,

[0054] If L2 > MaxL, the adjustment of the air flow rate from V0 to V2 is still considered uncontrollable. Therefore, the air flow rate value is updated again to V3, and the original step length Lv1 is halved to Lv2, that is, Lv2 = Lv1 / 2 = Lv0 / 4. The adjustment unit inversely assigns an air flow rate step length Lv2 to the natural logarithm value lnV0 of the current air flow rate to form an updated natural logarithm value lnV3.

[0055] If the current value ln COP0 is less than MinLnCOP, the adjustment value V3 needs to be adjusted to a higher value, lnV3=lnV0+Lv2, that is, V3=V0*e Lv2 On the contrary, if the current value ln COP0 is greater than the interval maximum value MaxLnCOP, the adjustment value V2 needs to be adjusted to a lower value, lnV3=lnV0-Lv2, that is, V3=V0 / e Lv2 .

[0056] And so on until the k-th adjustment values ΔTk, Pk, and Vk are sent back to the central processing unit (where k is an integer and k≥2), and the determination module calculates the vector distance Lk between these parameters and the parameters before the update. The calculation formula is as follows:

[0057] ,

[0058] Finally, if it is determined that Lk≤MaxL, it is determined that the adjustment of the air velocity from V0 to Vk is controllable, and the calculated step value is Lvk, where Lvk = Lv0 / 2 k .

[0059] Through the above iterative process, the step value Lvk is finally determined as the final adjustment step value of the finally determined air velocity.

[0060] In this case, the central processing unit calls its command module, and the command module remotely issues an instruction to the air supply device 5. When the natural logarithm of the initial performance coefficient ln COP0 < MinLnCOP, it is required that the air supply device 5 increase the initial air velocity V0 to V0 + V0 / e Lvk , and if after the adjustment, there is still ln COP < MinLnCOP, then another instruction is issued to increase the initial air velocity to V0 + 2*V0 / e Lvk , and then the size relationship between the adjusted performance coefficient COP and MinLnCOP is judged, and so on until the initial air velocity V0 is increased to V0 + n*V0 / e Lvk (where n is an integer and n≥2), thereby ensuring that the natural logarithm of the final COP is within the interval [MinLnCOP, MaxLnCOP].

[0061] On the contrary, when the natural logarithm of the initial performance coefficient ln COP0 > MaxLnCOP, it is required that the air supply device 5 decrease the initial air velocity V0 to V0 - V0 / e Lvk , and if the adjusted performance coefficient ln COP0 > MaxLnCOP, then another instruction is issued to decrease the initial air velocity to V0 - 2*V0 / e Lvk , and then the size relationship between the adjusted performance coefficient COP and MaxLnCOP is judged, and so on until the initial air velocity V0 is decreased to V0 - n*V0 / e Lvk (where n is an integer and n≥2), thereby ensuring that the natural logarithm of the final COP is within the interval [MinLnCOP, MaxLnCOP].

[0062] In other words, the command module reversely adjusts the air flow rate of the air supply device 5 according to the step value Lvk, thereby ensuring that the natural logarithm of the final COP is within the interval [MinLnCOP, MaxLnCOP].

[0063] This concludes the basic operation of the intelligent linkage system for solar panels and heat pumps provided by the present invention. During solar heating, the intelligent linkage system for solar panels and heat pumps provided by the present invention first effectively adjusts the three parameters of output power, air flow rate, and heat source temperature difference based on the relationships between the solar panels inside and outside the house, the air supply equipment, and the air source heat pump. This determines the magnitude of the air flow rate adjustment required when the heat pump's coefficient of performance (COP) exceeds the rated range, and then incrementally adjusts the air flow rate based on this magnitude, ensuring that the heat pump's COP is adjusted within a controllable range by rationally adjusting the air flow rate, thereby ensuring the proper operation of the entire solar system.

[0064] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
