[0020] Traditional refrigeration and heating equipment achieves refrigeration and heating through gas compressors. Among them, the refrigerants used in gas compression refrigerators (such as chlorine-containing and bromine-containing refrigerants) are toxic and are discharged into the environment in large quantities, causing a sharp drop in the ozone content in the atmosphere and causing irreversible damage to the atmosphere. Even if environmentally friendly refrigerants (such as fluorine-containing and ammonia-containing refrigerants) are used, there are great safety risks when using them because of their flammable and explosive disadvantages. In addition, the energy conversion rate of refrigeration and heating through gas compression is low, resulting in energy waste.

[0021] The spring card solid-state cooling and heating technology is a new type of space temperature control technology that is efficient and environmentally friendly. This technology induces phase change in the spring card material by mechanically deforming it, thereby generating latent heat release and absorption to achieve the purpose of cooling and heating.

[0022] Spring-cage materials refer to solid materials with spring-cage (thermal) effects, such as shape memory alloys, natural rubber, synthetic polymers, plastic crystals, etc.; among them, shape memory alloys (such as nickel-titanium alloys, copper-aluminum-manganese alloys, nickel-manganese-copper-cobalt alloys, nickel-iron-gallium alloys, etc.) have extremely high phase change entropy values ​​and material energy efficiency ratios, so they are widely used in spring-cage solid-state refrigeration technology.

[0023] The development trend of refrigeration and heating equipment is to use spring card materials to replace refrigeration and heating equipment using gas compressors. However, how to control refrigeration and heating devices using spring card materials is an urgent problem to be solved.

[0024] Based on this, the following embodiments of the present application propose a refrigeration and heating system and method using a spring-loaded material. In the refrigeration and heating system using a spring-loaded material, a controller and a first refrigeration and heating device connected to the controller are provided. The controller is used to obtain a control instruction carrying a current temperature and a target temperature, and then determine the temperature difference between the current temperature and the target temperature, and determine the refrigeration and heating capacity of the first refrigeration and heating device according to the temperature difference. Finally, based on the refrigeration and heating capacity, the operating time of the first refrigeration and heating device and the driving cycle of the spring-loaded material in the first refrigeration and heating device are obtained, and the first refrigeration and heating device is controlled to work according to the operating time and the driving cycle of the spring-loaded material, so that the operating time of the first refrigeration and heating device and the driving cycle of the spring-loaded material in the first refrigeration and heating device are obtained according to the required refrigeration and heating capacity, and the first refrigeration and heating device is controlled to work according to the obtained operating time and the driving cycle of the spring-loaded material, thereby completing the control of the refrigeration and heating system using the spring-loaded material, and the control process is simple and convenient.

[0025] Before describing the following embodiments, the following definitions are given:

[0026] Cooling and heating capacity, which can be positive or negative.

[0027] When the cooling and heating amount is a positive number, the cooling and heating system performs cooling operation.

[0028] When the cooling and heating amount is a negative number, the cooling and heating system performs heating operation.

[0029] In the refrigeration and heating system using spring-cage materials proposed in the present application, the first refrigeration and heating device and the second refrigeration and heating device respectively include: a pipeline and a medium material in the pipeline that can carry away the cold or heat generated by the pipeline structure.

[0030] The pipelines in the first refrigeration and heating device and the second refrigeration and heating device are made of spring-loaded material.

[0031] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Example 1

[0033] This embodiment provides a cooling and heating system using a spring-loaded material. The cooling and heating system includes a controller and a first cooling and heating device connected to the controller.

[0034] The above-mentioned spring-cage material is used to form the first cooling and heating device of the above-mentioned cooling and heating system.

[0035] The controller is used to execute the following steps (1) to (3):

[0036] (1) Obtaining a control instruction, wherein the control instruction carries the current temperature and the target temperature;

[0037] (2) determining a temperature difference between the current temperature and the target temperature, and determining a cooling and heating capacity of the first cooling and heating device based on the temperature difference;

[0038] (3) Based on the determined cooling and heating capacity, determine the operating time of the first cooling and heating device and the driving cycle of the spring material in the first cooling and heating device, and control the first cooling and heating device to work according to the operating time and the driving cycle.

[0039] In the above step (1), the control instruction is sent to the controller by a user in the space where the cooling and heating system is located.

[0040] In the above step (2), the difference between the current temperature and the target temperature is calculated, and the calculation result is the temperature difference between the current temperature and the target temperature.

[0041] The controller is pre-set with a correspondence between the temperature difference and the cooling and heating amount. Based on the correspondence between the temperature difference and the cooling and heating amount, the controller can query the cooling and heating amount that matches the temperature difference between the current temperature and the target temperature.

[0042] In actual applications, since the size of the space where the above-mentioned cooling and heating equipment is placed is uncertain, the heat required to reach the target temperature from the current temperature is related to the size of the space, and the required cooling and heating amount is different. Therefore, the cooling and heating amount in this embodiment is the cooling and heating amount within a certain time period (for example, unit time).

[0043] In the above step (3), specifically, the following steps (31) to (36) may be performed:

[0044] (31) Determine the driving frequency of the ejection material corresponding to the cooling and heating capacity;

[0045] (32) obtaining a driving cycle of the ejection material according to the driving frequency of the ejection material, wherein a single driving cycle includes: a loading time, a first waiting time, an unloading time, and a second waiting time;

[0046] (33) Obtaining the cooling and heating power ratio per unit mass of the spring-loaded material used by the first cooling and heating device and the mass of the spring-loaded material;

[0047] (34) The cooling power of the above-mentioned spring card material is calculated by the following formula:

[0048] The cooling power of the card material = cooling and heating power ratio per unit mass * driving frequency of the card material * mass of the card material;

[0049] (35) determining the operating time of the first cooling and heating device based on the cooling and heating capacity and the calculated cooling power of the spring card material;

[0050] (36) Controlling the first cooling and heating device to operate according to the determined operating time and driving cycle of the ejection material.

[0051] Generally, the more times the spring-stuck material is loaded or unloaded, the more heat and cold the spring-stuck material generates, that is, the greater the driving frequency, the greater the cooling and heating capacity. In order to facilitate quantitative control, in the above step (31), the controller pre-stores the corresponding relationship between the cooling and heating capacity and the driving frequency of the spring-stuck material, so through the corresponding relationship between the cooling and heating capacity and the driving frequency of the spring-stuck material, the driving frequency of the spring-stuck material corresponding to the cooling and heating capacity can be queried and determined.

[0052] The corresponding relationship between the cooling and heating amount and the driving frequency of the spring-cage material can be obtained by performing a driving experiment on the spring-cage material, that is, by counting the number of driving times and the generated cooling and heating amount.

[0053] In the above step (32), the driving period of the ejection material can be obtained by taking the inverse of the driving frequency of the ejection material.

[0054] The controller also stores the corresponding relationship between the cooling and heating amount, the driving cycle, the loading time of the driving cycle, the first waiting time of the driving cycle, the unloading time of the driving cycle and the second waiting time of the driving cycle.

[0055] The driving cycle is equal to the sum of the loading time of the driving cycle, the first waiting time of the driving cycle, the unloading time of the driving cycle and the second waiting time of the driving cycle.

[0056] It should be noted that the loading time is the time it takes for the drive to load the ejection material. During the loading process, the ejection material releases heat. The unloading time is the time it takes for the drive to unload the ejection material. During the unloading process, the ejection material absorbs heat. The first waiting time is the time it takes for the medium to absorb the heat released by the ejection material. The second waiting time is the time it takes for the medium to absorb the cold released by the ejection material.

[0057] Here, the heat released by the card material during loading and the heat absorbed during unloading are the same, that is, the absolute value of the cooling and heating amount generated by loading and unloading in the same driving cycle is the same, but in the actual application process, when the cooling and heating equipment uses the heating function or the cooling function, in order to obtain the heating or cooling amount to the maximum extent, the selected first waiting time and the second waiting time are different. That is, the loading time of the driving cycle corresponding to the positive cooling and heating amount, the first waiting time of the driving cycle, the unloading time of the driving cycle, and the second waiting time of the driving cycle corresponding to the negative cooling and heating amount are not the same. When the cooling function is selected and the cooling and heating amount is a positive number, the first waiting time is less than the second waiting time, which can maximize the amount of cold absorbed by the medium. When the heating function is selected and the cooling and heating amount is a negative number, the first waiting time is greater than the second waiting time, which can maximize the amount of cold absorbed by the medium.

[0058] Therefore, after obtaining the cooling and heating amount and the driving cycle, based on the correspondence between the cooling and heating amount, the driving cycle, the loading time of the driving cycle, the first waiting time of the driving cycle, the unloading time of the driving cycle and the second waiting time of the driving cycle, the controller can obtain the loading time of the driving cycle, the first waiting time of the driving cycle, the unloading time of the driving cycle and the second waiting time of the driving cycle that match the cooling and heating amount and the driving cycle.

[0059] In the above step (33), the cooling and heating power ratio per unit mass of the card material is pre-cached in the controller.

[0060] Each spring card material has different cooling and heating capabilities, and its cooling and heating power per unit mass is different. The cooling and heating power per unit mass ratio is the heat released when the unit mass of the spring card material is loaded to complete phase change, and the heat absorbed when the phase change is restored.

[0061] In addition to the cooling and heating power ratio per unit mass, the controller also stores the property information of the ejection material, such as the quantity, density and volume of the ejection material per unit mass.

[0062] In order to obtain the mass of the ejection material in the first cooling and heating device, the controller may first obtain the quantity of the ejection material and the volume of the unit ejection material, and then calculate the mass of the ejection material by the following formula:

[0063] The volume of the card material = the volume of the unit card material * the number of card materials

[0064] The mass of the card material = the volume of the card material * density

[0065] In the above step (35), the operating time of the first cooling and heating device is determined by the following formula:

[0066] The operation time of the first cooling and heating equipment = cooling and heating capacity / cooling power of the card material

[0067] In the above step (36), in the process of controlling the operation of the above-mentioned first refrigeration and heating equipment according to the determined operating time and the driving cycle of the ejection material, a dielectric material pump is set in the first refrigeration and heating equipment to blow the dielectric material into the pipeline of the first refrigeration and heating equipment to absorb heat and cold, and then the dielectric material pump is used to suck the dielectric material after absorbing heat into the heat exchange device, so that the dielectric material can take away the refrigeration and heating amount generated by the first refrigeration and heating equipment.

[0068] The dielectric material pump is connected to the controller and is used to blow the dielectric material into the pipeline of the first refrigeration and heating equipment under the control of the controller, and use the dielectric material to take away the refrigeration and heating amount generated by the first refrigeration and heating equipment.

[0069] Specifically, the above step (36) may also perform the following steps (360) to (369):

[0070] (360) obtaining the specific heat capacity and density of the medium material that absorbs the heat generated by the first cooling and heating generator during operation, and the cross-sectional area of ​​the pipeline through which the medium material flows; wherein the pipeline is a pipe structure in the cooling and heating generator in the first cooling and heating device for the medium material to flow;

[0071] (361) Querying the efficiency coefficient corresponding to the specific heat capacity and density of the above-mentioned medium material and the cross-sectional area of ​​the pipeline through which the above-mentioned medium material flows in the cooling and heating generator;

[0072] (362) calculating the total absorbed heat of the dielectric material according to the cooling and heating capacity and the efficiency coefficient obtained;

[0073] (363) determining the first waiting time or the second waiting time in the driving cycle of the ejection material as the medium dwelling time;

[0074] (364) calculating the amount of heat absorbed by the dielectric material during each dielectric residence time based on the total amount of heat absorbed by the dielectric material and the dielectric residence time;

[0075] (365) Based on the ratio of the medium residence time to the unit time and the amount of heat absorbed by the medium material during each medium residence time, the amount of heat absorbed by the medium material per unit time is calculated;

[0076] (366) Based on the total absorbed heat, current temperature and target temperature of the dielectric material, query the historical temperature difference between the temperature before and after the dielectric material absorbs the cooling heat generated by the dielectric material on the spring card material, corresponding to the total absorbed heat, current temperature and target temperature of the dielectric material;

[0077] (367) The flow rate of the medium material in the pipeline is calculated by the following formula:

[0078] Q 吸 =ηCρSv*ΔT

[0079] Among them, Q 吸 Indicates the amount of heat absorbed by the dielectric material per unit time; C indicates the specific heat capacity of the dielectric material; ρ indicates the density of the dielectric material; ΔT indicates the historical temperature difference between the temperature before and after the dielectric material absorbs the cooling heat generated by the dielectric material on the card material corresponding to the total absorbed heat of the dielectric material, the current temperature and the target temperature; v indicates the flow rate of the dielectric material in the pipeline; η indicates the efficiency coefficient;

[0080] (368) determining the pump power of the dielectric material pump that matches the flow rate by calculating the flow rate of the dielectric material in the pipeline, wherein the dielectric material pump is used to blow the dielectric material into the refrigeration and heating generator according to the determined pump power so that the dielectric material absorbs the heat generated by the refrigeration and heating generator, or blows the absorbed heat into the space where the refrigeration and heating system is located to perform heat exchange with the space where the refrigeration and heating system is located;

[0081] (369) Controlling the first cooling and heating device to operate according to the operating time, the driving cycle of the ejection material, and the pump power.

[0082] In the above step (360), the specific heat capacity and density of the medium material and the cross-sectional area of ​​the pipeline through which the medium material flows are all pre-stored in the controller.

[0083] In the above step (361), the controller is pre-set with the corresponding relationship between the specific heat capacity, density, cross-sectional area of ​​the pipeline through which the medium material flows, and efficiency coefficient of the medium material. From the corresponding relationship between the specific heat capacity, density, cross-sectional area of ​​the pipeline through which the medium material flows, and efficiency coefficient of the medium material, the efficiency coefficient corresponding to the specific heat capacity, density of the medium material and the cross-sectional area of ​​the pipeline through which the medium material flows in the refrigeration and heating generator can be queried.

[0084] It should be noted that when the heat or cold released by the spring card material is exchanged through the medium material, there is heat loss due to the design of the pipeline or spatial heat conduction. Therefore, the efficiency coefficient is obtained through experiments, that is, by changing factors such as the pipeline structure (such as cross-sectional area, pipeline shape, length, etc.), the type of medium material, and measuring the exchanged heat to obtain an empirical value.

[0085] In the above step (362), the total absorbed heat of the dielectric material is calculated by the following formula:

[0086] The total heat absorbed by the dielectric material = cooling heating capacity * efficiency coefficient.

[0087] In the above step (363), the medium material stays in the pipeline of the cooling and heating generator of the first cooling and heating equipment to take away the cooling and heating amount generated in the pipeline of the first cooling and heating equipment.

[0088] The medium residence time is the residence time of the medium material in the pipeline of the refrigeration and heating generator, that is, the time it takes for the medium material to completely absorb the heat or cold generated in the pipeline. The medium material begins to exchange heat when entering the pipeline. The longer its residence time, the more heat or cold it absorbs.

[0089] In order to determine the medium residence time, the controller can compare the first waiting time and the second waiting time to obtain the ratio of the first waiting time and the second waiting time; when the ratio of the first waiting time and the second waiting time is greater than 1 and a cooling operation is performed, the first waiting time is determined to be the medium residence time; when the ratio of the first waiting time and the second waiting time is less than 1 and a heating operation is performed, the second waiting time is determined to be the medium residence time.

[0090] It should be noted that when the cooling function is used, the medium residence time is the time the medium material absorbs cold (first waiting time), and when the heating function is used, the medium residence time is the time the medium material absorbs heat (second waiting time).

[0091] In the above step (364), the heat absorbed by the medium material during each medium residence time is calculated by the following formula:

[0092] The amount of heat absorbed by the dielectric material during each dielectric residence time = the total amount of heat absorbed by the dielectric material / media residence time.

[0093] In the above step (365), the ratio of the medium residence time to the unit time is calculated first, and then the calculated time ratio is multiplied by the heat absorbed by the medium material during each medium residence time, so that the heat absorbed by the medium material per unit time can be calculated.

[0094] In the above step (366), the controller pre-stores the corresponding relationship between the total absorbed heat of the dielectric material, the current temperature, the target temperature, and the historical temperature difference between the temperature before and after the dielectric material absorbs the cooling heat generated by the dielectric material on the card material.

[0095] This historical temperature difference is an empirical value.

[0096] In the above step (367), the empirical coefficient is a preset value.

[0097] In the above step (368), the controller pre-stores the corresponding relationship between the pump power of the dielectric material pump and the flow rate of the dielectric material in the pipeline.

[0098] The controller determines the pump power of the dielectric material pump that matches the flow rate from the correspondence between the pre-stored pump power of the dielectric material pump and the flow rate of the dielectric material in the pipeline.

[0099] The cooling and heating system proposed in this embodiment further includes: a display unit connected to the controller.

[0100] In addition to executing the above-mentioned process of steps (31) to (36), the controller may also execute the following steps (a) to (h):

[0101] (a) obtaining a refrigeration coefficient of the spring-cage material used in the first refrigeration and heating device, a driving cycle coefficient of the driving cycle of the spring-cage material, and a flow rate coefficient of the flow rate of the medium material in the pipeline;

[0102] (b) obtaining the actual flow rate of the medium material in the pipeline and the length of the pipeline;

[0103] (c) calculating an actual residence time of the medium material in the pipeline based on an actual flow rate of the medium material in the pipeline and a length of the pipeline;

[0104] (d) calculating a first ratio between an actual flow rate of the medium material in the pipeline and a flow rate of the medium material in the pipeline;

[0105] (e) obtaining the loading time and unloading time within the driving cycle of the above-mentioned ejection material, and using the above-mentioned actual residence time, loading time and unloading time, calculating the actual driving cycle of the above-mentioned ejection material;

[0106] (f) calculating a second ratio of the actual driving period of the spring-stuck material to the driving period;

[0107] (g) Calculate the cooling and heating index of the target cooling and heating equipment by the following formula:

[0108] Cooling and heating index = cooling coefficient + K1*first ratio + K2*second ratio

[0109] Among them, K1 and K2 are preset values;

[0110] (h) Display the above-calculated cooling and heating index.

[0111] In the above step (a), the refrigeration coefficient of the spring-cage material used in the first refrigeration and heating equipment, the driving cycle coefficient of the driving cycle of the spring-cage material, and the flow rate coefficient of the flow rate of the above medium material in the pipeline are all pre-stored in the controller of the first refrigeration and heating equipment.

[0112] In the above step (b), a flow meter communicating with the controller is provided in the pipeline.

[0113] During the operation of the first refrigeration and heating device, the flow meter arranged in the pipeline measures the actual flow rate of the medium material in the pipeline, and then sends the measured actual flow rate of the medium material in the pipeline to the controller.

[0114] The length of the above pipeline is pre-stored in the controller.

[0115] In the above step (c), the actual residence time of the above medium material in the above pipeline is calculated by the following formula:

[0116] The actual residence time in the pipeline = the actual flow rate of the medium material in the pipeline / the length of the pipeline.

[0117] In the above step (d), the first ratio=actual flow rate of the medium material in the pipeline / flow rate of the medium material in the pipeline.

[0118] In the above step (e), the controller may first use the actual dwell time to update the first waiting time or the second waiting time, and then use the updated first waiting time or the second waiting time to calculate the actual driving cycle of the ejection material.

[0119] When the medium residence time is the first waiting time, the first waiting time is updated with the actual residence time; otherwise, the second waiting time is updated with the actual residence time.

[0120] Specifically, in the case where the first waiting time is updated, the actual driving cycle of the ejection material=loading time+unloading time+second waiting time+updated first waiting time.

[0121] In the case where the second waiting time is updated, the actual driving cycle of the ejection material=loading time+unloading time+first waiting time+updated second waiting time.

[0122] In the above step (f), the second ratio=actual driving period of the spring-stuck material / driving period of the spring-stuck material.

[0123] In the above step (g), the preset values ​​K1 and K2 are pre-stored in the controller.

[0124] In the above step (h), the controller sends the calculated cooling and heating index to the display unit for display.

[0125] Furthermore, a second refrigeration and heating device may be provided in the refrigeration and heating system, wherein the spring card materials used in the first refrigeration and heating device and the second refrigeration and heating device are different, so that the refrigeration and heating powers of the first refrigeration and heating device and the second refrigeration and heating device are different in different temperature ranges.

[0126] The controller is connected to the second cooling and heating device.

[0127] In order to control the first cooling and heating device and the second cooling and heating device, the controller will respectively assign respective cooling and heating device identifiers to the first cooling and heating device and the second cooling and heating device, and control the first cooling and heating device.

[0128] The following steps (a1) to (a4) may be performed:

[0129] (a1) obtaining a control instruction, wherein the control instruction carries the current temperature and the target temperature;

[0130] (a2) determining a temperature interval to which the current temperature and the target temperature belong, and selecting a cooling and heating power matching the temperature interval from the first cooling and heating device and the second cooling and heating device, and determining the cooling and heating device corresponding to the cooling and heating power matching the temperature interval from the first cooling and heating device and the second cooling and heating device as the target cooling and heating device;

[0131] (a3) calculating the temperature difference between the current temperature and the target temperature, and determining the required cooling and heating amount according to the temperature difference;

[0132] (a4) Based on the determined cooling capacity, the operating time of the target cooling and heating equipment and the driving cycle of the ejection material in the target cooling and heating equipment are determined, and the target cooling and heating equipment is controlled to operate according to the determined operating time and the driving cycle of the ejection material.

[0133] In the above step (a2), the controller pre-stores the corresponding relationship between the cooling and heating equipment identification, the temperature range and the cooling and heating power.
