[0019] At present, refrigeration and heating equipment with spring-loaded card materials uses the spring-loaded card materials as refrigeration and heating generators in the refrigeration and heating equipment. The working principle of such refrigeration and heating generators is: mechanically deforming the spring-loaded card materials to induce phase change in the elastic materials, resulting in latent heat release and absorption, thereby utilizing the refrigeration and heating equipment to achieve the purpose of regulating the temperature.

[0020] In the related art, when a refrigeration and heating device fails, the refrigeration and heating device can only be replaced. Before the refrigeration and heating device is replaced, the user cannot continue to use the refrigeration and heating device, which greatly affects the user experience.

[0021] Based on this, an embodiment of the present application proposes a control method for a refrigeration and heating equipment. In a refrigeration and heating equipment with two refrigeration and heating devices, after determining a working refrigeration and heating device and a standby refrigeration and heating device, the working refrigeration and heating device is controlled to execute a first control instruction to adjust the environment requiring temperature adjustment from a first temperature to a second temperature. During the operation of the working refrigeration and heating device, the working parameters of the working refrigeration and heating device are collected. When it is determined according to the collected working parameters that the working refrigeration and heating device fails and the ambient temperature of the environment requiring temperature adjustment does not reach the second temperature, it is determined that the current working refrigeration and heating device has a fault and switches to the standby refrigeration and heating device to continue to execute the first control instruction.

When one of the two refrigeration and heating devices fails, the other refrigeration and heating device is started to work. Without replacing the refrigeration and heating equipment, it can be ensured that the refrigeration and heating equipment can continue to work when it fails, thereby greatly improving the user experience.

[0022] 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.

[0023] Example 1

[0024] The execution subject of the control method of the cooling and heating equipment proposed in this embodiment is the control unit.

[0025] See also Figure 1 The flowchart of a control method of a refrigeration and heating device is shown. This embodiment provides a control method of a refrigeration and heating device, which is used for a refrigeration and heating device using a spring card material. The refrigeration and heating device includes: a control unit, a first refrigeration and heating device and a second refrigeration and heating device. The control unit is connected to the first refrigeration and heating device and the second refrigeration and heating device respectively; the control method includes the following specific steps:

[0026] Step 100: Obtain a first control instruction, wherein the first control instruction includes: a current first temperature of an environment requiring temperature adjustment and a second temperature after temperature adjustment.

[0027] Step 102: Based on the temperature range in which the first temperature and the second temperature are located, a refrigeration and heating device with a higher refrigeration and heating power in the temperature range is selected from the first refrigeration and heating device and the second refrigeration and heating device as the working refrigeration and heating device, and a refrigeration and heating device with a lower refrigeration and heating power in the temperature range is selected as the standby refrigeration and heating device.

[0028] In the above step 102, the cooling and heating generator in the above-mentioned first cooling and heating device and the cooling and heating generator in the second cooling and heating device respectively have a plurality of spring-cage material units arranged in series or in parallel; each of the plurality of spring-cage material units is composed of spring-cage materials, and different spring-cage materials have different cooling and heating capabilities.

[0029] Since the spring card material used in the spring card material unit of the first cooling and heating device is different from the spring card material used in the spring card material unit of the second cooling and heating device, the cooling and heating power of the spring card material unit in the first cooling and heating device is different from the cooling and heating power of the spring card material unit in the second cooling and heating device in different temperature ranges.

[0030] The control unit pre-stores the corresponding relationship between the first cooling and heating device, the temperature range and the cooling and heating power, and the corresponding relationship between the second cooling and heating device, the temperature range and the cooling and heating power.

[0031] Then, based on the temperature range in which the first temperature and the second temperature are located, the correspondence between the above-mentioned first cooling and heating device, the temperature range and the cooling and heating power, and the correspondence between the above-mentioned second cooling and heating device, the temperature range and the cooling and heating power, the control unit can select a cooling and heating device with higher cooling and heating power in the above-mentioned temperature range from the first cooling and heating device and the second cooling and heating device as the working cooling and heating device, and select a cooling and heating device with lower cooling and heating power in the temperature range as the standby cooling and heating device.

[0032] Step 104, control the working cooling and heating device to execute the first control instruction, adjust the environment requiring temperature adjustment from the first temperature to the second temperature, and collect the working parameters of the working cooling and heating device during the working process of the working cooling and heating device.

[0033] In the above step 104, in order to collect the working parameters of the above working cooling and heating devices, the above cooling and heating equipment also includes: power sensors respectively installed on the cooling and heating generators in the first cooling and heating device and the second cooling and heating device; the power sensors are connected to the control unit.

[0034] In order to collect the working parameters of the above-mentioned working cooling and heating devices, the above-mentioned cooling and heating equipment also includes: flow rate sensors respectively installed on the cooling and heating generators in the above-mentioned first cooling and heating device and the second cooling and heating device; the flow rate sensor is connected to the control unit.

[0035] In order to collect the working parameters of the above-mentioned working cooling and heating devices, the above-mentioned cooling and heating equipment further includes: microphones respectively installed in the above-mentioned first cooling and heating device and the second cooling and heating device; the above-mentioned microphones are connected to the above-mentioned control unit;

[0036] In order to collect the working parameters of the above-mentioned working cooling and heating devices, the above-mentioned cooling and heating equipment also includes: current sensors respectively installed in the above-mentioned first cooling and heating device and the second cooling and heating device; the above-mentioned current sensors are connected to the above-mentioned control unit.

[0037] The above working parameters include, but are not limited to: actual value of cooling and heating power, actual value of medium material flow rate, operating sound data, and current value.

[0038] In order to enable the working refrigeration and heating device to work normally, the control unit needs to first calculate the operating time of the working refrigeration and heating device, the quality of the spring card material, the driving cycle of the spring card material of the working refrigeration and heating device, the cooling and heating power calculation value of the spring card material unit of the working refrigeration and heating device, and the medium material flow rate calculation value of the medium material in the pipeline of the spring card material unit of the working refrigeration and heating device. After the calculation is completed, the control unit controls the working refrigeration and heating device to execute the first control instruction based on the parameters obtained by the above calculations, and adjusts the environment that requires temperature adjustment from the first temperature to the second temperature.

[0039] Among them, the spring-loaded material unit of the working cooling and heating device is used to generate cooling and heating amount to adjust the environment from the first temperature to the second temperature.

[0040] The dielectric material is used to carry away the cooling and heating amount generated by the pipeline of the card material unit so that the card material unit can work normally; the dielectric material can be but is not limited to: water, ethylene glycol and heat transfer oil.

[0041] The mass of the spring card material is obtained by multiplying the total mass of the spring card material in the working refrigeration and heating device by the mass coefficient. It is the mass of the spring card material that has just started working in the working refrigeration and heating device, and can be used to calculate the number of spring card units that have just started working in the working refrigeration and heating device.

[0042] Here, the quality coefficient is pre-set in the control unit, and the quality coefficient is any value between 0.6 and 0.8, which will not be described in detail here.

[0043] The number of the spring card units that have just started working in the working cooling and heating device can be obtained by multiplying the mass coefficient by the total number of spring card materials.

[0044] The total mass of the ejection material is calculated by the total volume and density of the ejection material. The total volume and density of the ejection material are preset in the control unit.

[0045] Since each of the spring card material units is formed by the spring card material, the driving cycle of the spring card material unit is the driving cycle of the spring card material.

[0046] The driving frequency of the spring card material is the inverse of the driving period of the spring card material. The driving frequency of the spring card material unit is the driving frequency of the spring card material.

[0047] The specific calculation process of the control unit for parameters such as the operating time of the working refrigeration and heating device, the mass of the spring card material, the driving cycle of the spring card material of the working refrigeration and heating device, the calculated value of the refrigeration and heating power of the spring card material unit of the working refrigeration and heating device, and the calculated value of the flow rate of the medium material in the pipeline of the spring card material unit of the working refrigeration and heating device is not the focus of this application, and reference may be made to other related patents.

[0048] Step 106: When it is determined based on the collected working parameters that the working cooling and heating device fails and the ambient temperature of the environment requiring temperature adjustment does not reach the second temperature, switch from the working cooling and heating device to the standby cooling and heating device, and control the standby cooling and heating device to continue to execute the first control instruction.

[0049] In the above step 106, when the working parameter is the actual value of the cooling and heating power, the following steps (1) to (5) may be performed:

[0050] (1) obtaining the actual cooling and heating power of the cooling and heating generator in the working cooling and heating device collected by the power sensor;

[0051] (2) obtaining a pre-calculated cooling and heating power calculation value of the above-mentioned working cooling and heating device;

[0052] (3) calculating a first ratio of the actual cooling and heating power to the calculated cooling and heating power;

[0053] (4) when the calculated first ratio is less than a first ratio threshold, determining that the working cooling and heating device fails, and obtaining the ambient temperature of the environment;

[0054] (5) When the acquired ambient temperature is different from the second temperature, the working cooling and heating device is switched to the standby cooling and heating device, and the standby cooling and heating device is controlled to continue to execute the first control instruction.

[0055] In the above step (2), the calculated cooling and heating power value of the working cooling and heating device is pre-calculated by the control unit before the working cooling and heating device starts working in order to control the working cooling and heating device to work.

[0056] In the above step (3), the first ratio threshold is pre-stored in the control unit.

[0057] In the above step (4), the control unit obtains the ambient temperature of the above environment in real time through a temperature sensor arranged in the above environment.

[0058] In the above step (5), "switching from the above working cooling and heating device to the above standby cooling and heating device, and controlling the above standby cooling and heating device to continue to execute the above first control instruction" means that the control unit stops the operation of the above working cooling and heating device, starts the above standby cooling and heating device and controls the above standby cooling and heating device to continue to execute the above first control instruction.

[0059] When the working parameter is the actual value of the flow rate of the medium material, the above step 106 can perform the following steps (6) to (10):

[0060] (6) obtaining an actual value of the flow rate of the medium material in the cooling and heating generator in the working cooling and heating device collected by the flow rate sensor;

[0061] (7) obtaining a pre-calculated value of the flow rate of the medium material of the above-mentioned working refrigeration and heating device;

[0062] (8) calculating a second ratio of the actual value of the medium material flow rate to the calculated value of the medium material flow rate;

[0063] (9) when the calculated second ratio is less than a second ratio threshold, determining that the working cooling and heating device fails, and obtaining the ambient temperature of the environment;

[0064] (10) When the acquired ambient temperature is different from the second temperature, the working cooling and heating device is switched to the standby cooling and heating device, and the standby cooling and heating device is controlled to continue to execute the first control instruction.

[0065] In the above step (9), the second ratio threshold is pre-cached in the control unit.

[0066] The control unit obtains the ambient temperature of the environment in real time through a temperature sensor arranged in the environment.

[0067] When the working parameter is the running sound data, the above step 106 may perform the following steps (11) to (15):

[0068] (11) obtaining the operating sound data of the working cooling and heating device collected by the microphone;

[0069] (12) parsing the acquired operation sound data to obtain the voiceprint features of the operation sound data;

[0070] (13) classifying the voiceprint features of the operating sound data using a pre-trained fault sound analysis model to obtain a classification result of the voiceprint features of the operating sound data;

[0071] (14) when the classification result indicates that the voiceprint feature of the operating sound data belongs to a fault sound, determining that the operating cooling and heating device has a fault, and obtaining the ambient temperature of the environment;

[0072] (15) When the acquired ambient temperature is different from the second temperature, the working cooling and heating device is switched to the standby cooling and heating device, and the standby cooling and heating device is controlled to continue to execute the first control instruction.

[0073] In the above step (12), the specific process of parsing the acquired operation sound data to obtain the voiceprint features of the above operation sound data is prior art and will not be repeated here.

[0074] In the above step (13), the voiceprint features of the above operating sound data are classified by a pre-trained fault sound analysis model. The specific process of obtaining the classification result of the voiceprint features of the above operating sound data is prior art and will not be repeated here.

[0075] The above classification results include: classification results of fault sounds and normal operation sounds.

[0076] In the above step (14), the control unit obtains the ambient temperature of the above environment in real time through a temperature sensor arranged in the above environment.

[0077] When the working parameter is a current value, the above step 106 may perform the following steps (16) to (19):

[0078] (16) obtaining the current value of the working cooling and heating device collected by the current sensor;

[0079] (17) calculating the current value difference between the current value and the current value obtained last time;

[0080] (18) when the calculated current value difference is greater than a preset current difference threshold, determining that the working cooling and heating device fails, and obtaining the ambient temperature of the environment;

[0081] (19) When the acquired ambient temperature is different from the second temperature, the working cooling and heating device is switched to the standby cooling and heating device, and the standby cooling and heating device is controlled to continue to execute the first control instruction.

[0082] In the above step (18), the above current difference threshold is pre-cached in the control unit.

[0083] The control unit obtains the ambient temperature of the environment in real time through a temperature sensor arranged in the environment.

[0084] In the above step 104, in order to increase the accuracy of temperature control in the process of controlling the above working cooling and heating device to execute the above first control instruction and adjusting the environment requiring temperature adjustment from the above first temperature to the above second temperature, the following steps (20) to (22) may be performed:

[0085] (20) calculating a temperature difference between the first temperature and the second temperature, and determining a matching cooling and heating amount according to the temperature difference;

[0086] (21) when the required cooling and heating capacity determined is less than or equal to the maximum cooling and heating capacity of the working cooling and heating device, controlling the working cooling and heating device to execute the first control instruction to adjust the environment requiring temperature adjustment from the first temperature to the second temperature;

[0087] (22) When the required cooling and heating capacity determined is greater than the maximum cooling and heating capacity of the working cooling and heating device, the working cooling and heating device and the standby cooling and heating device are controlled to operate simultaneously and execute the first control instruction together to adjust the environment requiring temperature adjustment from the first temperature to the second temperature.

[0088] In the above step (20), the control unit is pre-set with a corresponding relationship between the temperature difference and the cooling and heating amount. Then, according to the calculated temperature difference between the first temperature and the second temperature, the cooling and heating amount matching the temperature difference can be determined from the corresponding relationship between the temperature difference and the cooling and heating amount.

[0089] In the above step (22), the specific process of the control unit controlling the standby cooling and heating device is similar to the process of the control unit controlling the working cooling and heating device, which will not be repeated here.

[0090] Optionally, in order to increase the accuracy of temperature control during the process of adjusting the environment from the first temperature to the second temperature, the above step 104 may further continue to perform the following steps (23) to (26):

[0091] (23) collecting the current ambient temperature of the environment while controlling the working cooling and heating device and the standby cooling and heating device to operate simultaneously;

[0092] (24) determining whether the temperature difference between the current ambient temperature and the second temperature is greater than or equal to a first temperature threshold, if yes, executing step (25), if no, executing step (26);

[0093] (25) Return and execute the above step (23);

[0094] (26) Sending a stop operation instruction to the standby cooling and heating device, and controlling the working cooling and heating device to continue to operate, so as to adjust the environment from the current ambient temperature to the second temperature.

[0095] In the above step (23), the current ambient temperature of the above environment is collected by a temperature sensor set in the environment. The temperature sensor can interact with the control unit, so the temperature sensor can send the collected current ambient temperature to the control unit.

[0096] In the above step (24), the first temperature threshold is pre-stored in the control unit.

[0097] Optionally, in order to save energy consumption of the working refrigeration and heating device while accurately controlling the ambient temperature, the driving frequency of the spring material can be reduced. In addition to the above step (26), the following steps (27) to (31) can also be performed:

[0098] (27) obtaining a first driving frequency of the spring card material corresponding to the above-mentioned cooling and heating amount;

[0099] (28) obtaining a driving cycle of the ejection material according to the first 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;

[0100] (29) obtaining a first waiting time update value corresponding to a temperature difference between the current ambient temperature and the second temperature;

[0101] (30) using the acquired first waiting time update value, respectively incrementing the length of the first waiting time and the second waiting time, thereby extending the driving cycle of the ejection material;

[0102] (31) Controlling the spring-loaded material unit in the cooling and heating generator of the working cooling and heating device to continue to operate according to the extended driving cycle of the spring-loaded material, and adjusting the environment from the current ambient temperature to the second temperature.

[0103] In the above step (27), the control unit pre-stores the corresponding relationship between the cooling and heating amount and the driving frequency of the ejection material.

[0104] The control unit can query and obtain the first driving frequency of the spring card material corresponding to the cooling and heating amount based on the corresponding relationship between the cooling and heating amount and the driving frequency of the spring card material.

[0105] In the above step (29), the control unit pre-stores the corresponding relationship between the temperature difference value and the waiting time update value.

[0106] The control unit may first calculate the temperature difference between the current ambient temperature and the second temperature, and then query and obtain the first waiting time update value corresponding to the temperature difference between the current ambient temperature and the second temperature from the correspondence between the temperature difference and the waiting time update value.

[0107] In the above step (30), extending the driving period of the above spring-stuck material means reducing the driving frequency of the spring-stuck material.

[0108] Optionally, the precise temperature control of the ambient temperature can be achieved by increasing / decreasing the number of the spring material units in the working cooling and heating device. In the above step (26), the following steps (32) to (37) can also be performed:

[0109] (32) Obtaining the mass of the above-mentioned spring card material corresponding to the above-mentioned cooling and heating capacity;

[0110] (33) determining a first number of spring material units operating in the cooling and heating generator of the currently operating cooling and heating device according to the obtained mass of the spring material;

[0111] (34) obtaining a second number of spring material units corresponding to a temperature difference between the current ambient temperature and the second temperature;

[0112] (35) calculating the difference between the first quantity and the second quantity;

[0113] (36) When the quantity difference is a positive number, the number of the spring-loaded material units corresponding to the quantity difference is controlled to stop working, so that the second number of the spring-loaded material units in the cooling and heating generator of the working cooling and heating device continue to work, and the environment is adjusted from the current environment temperature to the second temperature;

[0114] (37) When the above-mentioned quantity difference is a negative number, the spring-loaded material units of the quantity controlled by the above-mentioned quantity difference start to work, so that the above-mentioned second quantity of spring-loaded material units in the cooling and heating generator of the above-mentioned working cooling and heating device continue to work, and adjust the above-mentioned environment from the above-mentioned current ambient temperature to the above-mentioned second temperature.

[0115] In the above step (32), the mass of the spring card material corresponding to the cooling and heating amount is the mass of the spring card material that can adjust the environment from the first temperature to the second temperature and emit the above cooling and heating amount during the operating time of the working cooling and heating device.

[0116] When the control unit controls the working cooling and heating device to start working, it will calculate the mass of the above-mentioned spring card material corresponding to the above-mentioned cooling and heating amount, and then cache the calculated mass of the above-mentioned spring card material corresponding to the above-mentioned cooling and heating amount.

[0117] In the above step (33), the first number of the ejection material units is equal to the mass of the ejection material divided by the mass of a single ejection material unit.

[0118] The control unit pre-buffers the mass of a single ejection material unit. In the above step (34), the control unit pre-sets a corresponding relationship between the temperature difference and the number of ejection material units.

[0119] The control unit can obtain the second number of the ejection material units corresponding to the temperature difference between the current ambient temperature and the second temperature from the corresponding relationship between the temperature difference and the number of the ejection material units.

[0120] In addition to the above-mentioned troubleshooting and precise temperature control methods, the control unit can also control the cooling and heating equipment through zone temperature control.

[0121] In the case where the environment in which the above-mentioned cooling and heating equipment is located is divided into two different temperature adjustment areas, the two cooling and heating devices can also be installed in the two different temperature adjustment areas respectively.

[0122] In order to perform zone temperature control on the cooling and heating equipment, the control method of the cooling and heating equipment proposed in this embodiment may further include the following steps (40) to (42):

[0123] (40) obtaining a required temperature adjustment instruction for each of the different temperature adjustment areas, wherein the temperature adjustment instruction for each of the temperature adjustment areas includes: a current fifth temperature and a sixth temperature after temperature adjustment for each of the temperature adjustment areas;

[0124] (41) determining the cooling and heating capacity of each temperature adjustment area according to the current fifth temperature of each temperature adjustment area and the sixth temperature after the temperature adjustment;

[0125] (42) Based on the determined cooling and heating capacity of each temperature control area, the cooling and heating devices installed in each temperature control area are controlled to adjust the temperature of each of the above temperature control areas, thereby performing different temperature control on each temperature control area.

[0126] In the above step (41), the temperature difference between the current fifth temperature and the sixth temperature after temperature adjustment of each temperature adjustment area is used to determine the cooling and heating capacity of each temperature adjustment area from the correspondence between the preset temperature difference and the cooling and heating capacity.

[0127] In the above step (42), in order to control the cooling and heating devices installed in each temperature control area to adjust the temperature of each temperature control area based on the determined cooling and heating capacity of each temperature control area, the following steps (421) to (423) may be performed:

[0172] (56) Based on the cooling and heating amount adjusted to the ninth temperature, the cooling and heating device installed in the temperature adjustment area is controlled to adjust the temperature in the target temperature adjustment area, so that the temperature in the temperature adjustment area is adjusted to the ninth temperature.

[0173] In the above step (51), the control unit processes the above regional image and determines the specific process of the image features of the objects placed in the above temperature adjustment area, which is prior art and will not be described in detail here.

[0174] In the above step (52), an item classification model is pre-set in the control unit.

[0175] The specific process in which the control unit processes the image features of the above-mentioned object through the above-mentioned object classification model to determine the object type of the above-mentioned object placed in the above-mentioned temperature adjustment area is prior art and will not be repeated here.

[0176] In the above step (53), the corresponding relationship between the item type and the temperature is pre-set in the control unit.
