[0003] Currently, refrigeration and heating equipment using spring-loaded materials uses the spring-loaded materials as the refrigeration and heating generator. The working principle of such a refrigeration and heating generator is to induce a phase change in the spring-loaded materials by mechanically deforming them, thereby generating latent heat release and absorption, and thus using the refrigeration and heating equipment to achieve the purpose of temperature regulation.
[0004] In related technologies, when refrigeration and heating equipment malfunctions, the only solution is to replace the equipment. Before the equipment is replaced, users cannot continue to use it, which greatly affects the user experience. Summary of the Invention
[0005] To address the aforementioned problems, the purpose of this application is to provide a control method for a refrigeration and heating device.
[0006] In a first aspect, embodiments of this application provide a control method for a refrigeration and heating device, used in a refrigeration and heating device employing a spring-loaded material. The refrigeration and heating device includes: a control unit and a first refrigeration and heating device and a second refrigeration and heating device, wherein the control unit is connected to both the first and second refrigeration and heating devices; the control method includes:
[0007] The control unit acquires a first control command, the first control command including: the current first temperature of the environment requiring temperature adjustment and the second temperature after temperature adjustment;
[0008] Based on the temperature range of the first temperature and the second temperature, the refrigeration and heating device with higher refrigeration and heating power in the temperature range is selected as the working refrigeration and heating device from the first refrigeration and heating device and the refrigeration and heating device with lower refrigeration and heating power in the temperature range is selected as the standby refrigeration and heating device.
[0009] The working cooling and heating device is controlled to execute the first control command to adjust the environment requiring temperature regulation from the first temperature to the second temperature, and the working parameters of the working cooling and heating device are collected during the operation of the working cooling and heating device.
[0010] When it is determined from the collected operating parameters that the working cooling and heating device has malfunctioned and the ambient temperature of the environment requiring temperature regulation has not reached the second temperature, the system switches from the working cooling and heating device to the standby cooling and heating device and controls the standby cooling and heating device to continue executing the first control command.
[0011] In the solution provided by the first aspect of this application embodiment, in a refrigeration and heating equipment with two refrigeration and heating devices, after determining the working refrigeration and heating device and the standby refrigeration and heating device, the working refrigeration and heating device is controlled to execute a first control command to adjust the environment requiring temperature regulation from a first temperature to a second temperature.

Compared with the related technology where the refrigeration and heating equipment can only be replaced when it malfunctions, by setting two refrigeration and heating devices in the refrigeration and heating equipment, when one of the two refrigeration and heating devices malfunctions, the other refrigeration and heating device is started to work.

[0023] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] Example 1
[0025] The control method for the refrigeration and heating equipment proposed in this embodiment is executed by a control unit.
[0026] Referring to the flowchart of a control method for a refrigeration and heating device shown in Figure 1, this embodiment proposes a control method for a refrigeration and heating device using spring-loaded 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 both the first and second refrigeration and heating devices. The control method includes the following specific steps:
[0027] Step 100: Obtain the first control command, which includes: the current first temperature of the environment requiring temperature adjustment and the second temperature after temperature adjustment.
[0028] Step 102: Based on the temperature range of the first temperature and the second temperature, select the refrigeration and heating device with higher refrigeration and heating power in the above temperature range from the first refrigeration and heating device and the second refrigeration and heating device as the working refrigeration and heating device, and select the refrigeration and heating device with lower refrigeration and heating power in the above temperature range as the standby refrigeration and heating device.
[0029] In step 102 above, the cooling and heating generator in the first cooling and heating device and the cooling and heating generator in the second cooling and heating device each have multiple spring clip material units arranged in series or in parallel; each spring clip material unit is composed of spring clip material, and different spring clip materials have different cooling and heating capabilities.
[0030] Since the spring-loaded material used in the spring-loaded material unit of the first refrigeration and heating device is different from that used in the spring-loaded material unit of the second refrigeration and heating device, the refrigeration and heating power of the spring-loaded material unit in the first refrigeration and heating device is different from that in the second refrigeration and heating device in different temperature ranges.
[0031] The control unit stores in advance the correspondence between the first cooling and heating device, the temperature range, and the cooling and heating power, as well as the correspondence between the second cooling and heating device, the temperature range, and the cooling and heating power.
[0032] Based on the temperature ranges of the first and second temperatures, the correspondence between the first cooling / heating device, the temperature range, and the cooling / heating power, and the correspondence between the second cooling / heating device, the temperature range, and the cooling / heating power, the control unit can select the cooling / heating device with higher cooling / heating power in the aforementioned temperature range from the first and second cooling / heating devices as the working cooling / heating device, and select the cooling / heating device with lower cooling / heating power in the aforementioned temperature range as the backup cooling / heating device.
[0033] Step 104: Control the above-mentioned working cooling and heating device to execute the above-mentioned first control command, adjust the environment requiring temperature adjustment from the above-mentioned first temperature to the above-mentioned second temperature, and collect the working parameters of the above-mentioned working cooling and heating device during the operation of the above-mentioned working cooling and heating device.
[0034] In step 104 above, in order to collect the working parameters of the above-mentioned working cooling and heating device, the above-mentioned cooling and heating device further includes: a power sensor installed on the cooling and heating generator in the first cooling and heating device and the second cooling and heating device respectively; the power sensor is connected to the control unit.
[0035] In order to collect the operating parameters of the above-mentioned refrigeration and heating devices, the above-mentioned refrigeration and heating devices further include: a flow rate sensor installed on the refrigeration and heating generators in the first refrigeration and heating devices and the second refrigeration and heating devices respectively; the flow rate sensor is connected to the control unit.
[0036] In order to collect the operating parameters of the aforementioned cooling and heating devices, the aforementioned cooling and heating devices further include: microphones respectively installed in the first cooling and heating devices and the second cooling and heating devices; the microphones are connected to the aforementioned control unit;
[0037] In order to collect the operating parameters of the aforementioned refrigeration and heating devices, the aforementioned refrigeration and heating equipment further includes: current sensors respectively installed in the first refrigeration and heating devices and the second refrigeration and heating devices; the current sensors are connected to the aforementioned control unit.
[0038] The above operating parameters include, but are not limited to: actual values of cooling and heating power, actual values of medium material flow rate, operating sound data, and current values.
[0039] In order for the working cooling and heating device to function properly, the control unit needs to first calculate the operating time of the working cooling and heating device, the mass of the cartridge material, the driving cycle of the cartridge material, the cooling and heating power of the cartridge material unit, and the flow rate of the medium material in the cartridge material unit's pipeline. Based on the parameters obtained from the above calculations, the control unit controls the working cooling and heating device to execute the first control command to adjust the environment requiring temperature regulation from the first temperature to the second temperature.
[0040] The spring-loaded material unit of the working cooling and heating device is used to generate cooling and heating capacity to adjust the environment from a first temperature to a second temperature.
[0041] The medium material is used to remove the heat generated by the piping of the spring-loaded material unit, so that the spring-loaded material unit can work normally; the medium material can be, but is not limited to, water, ethylene glycol and heat transfer oil.
[0042] The mass of the spring clip material is obtained by multiplying the total mass of the spring clip material in the working refrigeration and heating device by the mass coefficient. It is the mass of the spring clip material at the beginning of operation in the working refrigeration and heating device, and can be used to calculate the number of spring clip units at the beginning of operation in the working refrigeration and heating device.
[0043] Here, the quality coefficient is preset in the control unit, and the quality coefficient is any value between 0.6 and 0.8, which will not be elaborated here.
[0044] The number of spring-loaded units that start working in the working cooling and heating device can be obtained by multiplying the mass coefficient by the total amount of spring-loaded material.
[0045] The total mass of the cartridge material is calculated using its total volume and density. The total volume and density of the cartridge material are preset in the control unit.
[0046] Since each cartridge material unit is composed of cartridge material, the driving cycle of the cartridge material unit is the driving cycle of the cartridge material.
[0047] The driving frequency of the cartridge material is the reciprocal of the driving cycle of the cartridge material. The driving frequency of the cartridge material unit is the driving frequency of the cartridge material.
[0048] The specific calculation process of parameters such as the running time of the working cooling and heating device, the mass of the cartridge material, the driving cycle of the cartridge material of the working cooling and heating device, the calculated value of the cooling and heating power of the cartridge material unit of the working cooling and heating device, and the calculated value of the flow rate of the medium material in the pipeline of the cartridge material unit of the working cooling and heating device are not the focus of this application. Please refer to other relevant patents.
[0049] Step 106: When it is determined from the collected working parameters that the working cooling and heating device has malfunctioned and the ambient temperature of the environment requiring temperature adjustment has not reached 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 executing the first control command.
[0050] In step 106 above, if the operating parameters are the actual values of cooling and heating power, the following steps (1) to (5) can be performed:
[0051] (1) Obtain the actual cooling and heating power of the cooling and heating generator in the above-mentioned working cooling and heating device collected by the above-mentioned power sensor;
[0052] (2) Obtain the pre-calculated cooling and heating power value of the above-mentioned working cooling and heating device;
[0053] (3) Calculate the first ratio between the actual value of the above-mentioned cooling and heating power and the calculated value of the above-mentioned cooling and heating power;
[0054] (4) When the calculated first ratio is less than the first ratio threshold, it is determined that the working cooling and heating device has malfunctioned, and the ambient temperature of the environment is obtained.
[0055] (5) When the obtained ambient temperature is different from 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 command.
[0056] In step (2) above, the calculated value of the cooling and heating power of the working cooling and heating device is calculated in advance by the control unit in order to control the working cooling and heating device to work before the working cooling and heating device starts working.
[0057] In step (3) above, the first proportional threshold is pre-stored in the control unit.
[0058] In step (4) above, the control unit obtains the ambient temperature of the environment in real time through a temperature sensor set in the environment.
[0059] In step (5) above, “switching from the working cooling and heating device to the standby cooling and heating device and controlling the standby cooling and heating device to continue executing the first control command” means that while the control unit stops the working cooling and heating device from working, it starts the standby cooling and heating device and controls the standby cooling and heating device to continue executing the first control command.
[0060] When the working parameters are the actual values of the medium material flow rate, step 106 above can be performed as follows: (6) to (10)
[0061] (6) Obtain the actual flow rate of the medium material in the refrigeration and heating generator of the above-mentioned working refrigeration and heating device, as collected by the above-mentioned flow rate sensor.
[0062] (7) Obtain the calculated value of the medium material flow rate of the above-mentioned working refrigeration and heating device obtained in advance;
[0063] (8) Calculate the second ratio between the actual value of the flow velocity of the above-mentioned medium material and the calculated value of the flow velocity of the above-mentioned medium material;
[0064] (9) When the calculated second ratio is less than the second ratio threshold, it is determined that the working cooling and heating device has malfunctioned, and the ambient temperature of the environment is obtained.
[0065] (10) When the obtained ambient temperature is different from 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 command.
[0066] In step (9) above, the second proportional threshold is pre-cached in the control unit.
[0067] The control unit obtains the ambient temperature of the environment in real time through a temperature sensor installed in the environment.
[0068] When the operating parameters are the running sound data, step 106 above can perform the following steps (11) to (15):
[0069] (11) Obtain the operating sound data of the above-mentioned working cooling and heating device collected by the above-mentioned microphone;
[0070] (12) The obtained operating sound data is analyzed to obtain the voiceprint features of the operating sound data;
[0071] (13) The voiceprint features of the above-mentioned operating sound data are classified by the pre-trained fault sound analysis model to obtain the classification results of the voiceprint features of the above-mentioned operating sound data.
[0072] (14) When the above classification result indicates that the voiceprint feature of the above operating sound data belongs to the fault sound, it is determined that the above working cooling and heating device has malfunctioned, and the ambient temperature of the above environment is obtained.
[0073] (15) When the obtained ambient temperature is different from 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 command.
[0074] In step (12) above, the specific process of parsing the obtained operating sound data to obtain the voiceprint features of the operating sound data is existing technology and will not be described in detail here.
[0075] In step (13) above, the specific process of classifying the voiceprint features of the above-mentioned operating sound data by using a pre-trained fault sound analysis model to obtain the classification results of the voiceprint features of the above-mentioned operating sound data is existing technology and will not be described in detail here.
[0076] The above classification results include the classification results for fault sounds and normal operating sounds.
[0077] In step (14) above, the control unit obtains the ambient temperature of the environment in real time through a temperature sensor set in the environment.
[0078] When the operating parameter is a current value, step 106 above can perform the following steps (16) to (19):
[0079] (16) Obtain the current value of the working cooling and heating device collected by the current sensor.
[0080] (17) Calculate the difference between the above current value and the current value obtained last time;
[0081] (18) When the calculated current difference is greater than the preset current difference threshold, it is determined that the above-mentioned working cooling and heating device has malfunctioned, and the ambient temperature of the above-mentioned environment is obtained.
[0082] (19) When the obtained ambient temperature is different from 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 command.
[0083] In step (18) above, the current difference threshold is pre-cached in the control unit.
[0084] The control unit obtains the ambient temperature of the environment in real time through a temperature sensor installed in the environment.
[0085] In step 104 above, in order to increase the accuracy of temperature control during the process of controlling the above-mentioned working cooling and heating device to execute the above-mentioned first control command and adjust the environment requiring temperature adjustment from the above-mentioned first temperature to the above-mentioned second temperature, the following steps (20) to (22) can be performed:
[0086] (20) Calculate the temperature difference between the first temperature and the second temperature, and determine the matching cooling and heating capacity based on the temperature difference.
[0087] (21) When the determined required cooling capacity is less than or equal to the maximum cooling capacity of the working cooling and heating device, the working cooling and heating device is controlled to execute the first control command to adjust the environment requiring temperature adjustment from the first temperature to the second temperature.
[0088] (22) When the determined required cooling capacity is greater than the maximum cooling capacity of the working cooling and heating device, the working cooling and heating device and the standby cooling and heating device are controlled to work simultaneously and execute the first control command together to adjust the environment requiring temperature adjustment from the first temperature to the second temperature.
[0089] In step (20) above, the control unit has a pre-set correspondence between temperature difference and cooling / heating capacity. Therefore, based on the calculated temperature difference between the first and second temperatures, the cooling / heating capacity matching the temperature difference can be determined from the above correspondence between temperature difference and cooling / heating capacity.
[0090] In step (22) above, 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, and will not be repeated here.
[0091] 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, step 104 above may continue to perform the following steps (23) to (26):
[0092] (23) During the process of controlling the above-mentioned working cooling and heating device and the above-mentioned standby cooling and heating device to work simultaneously, the current ambient temperature of the above-mentioned environment is collected.
[0093] (24) Determine whether the temperature difference between the current ambient temperature and the second temperature is greater than or equal to the first temperature threshold. If yes, proceed to step (25); otherwise, proceed to step (26).
[0094] (25) Return and perform the above step (23);
[0095] (26) Send a stop operation command to the standby cooling and heating device and control the working cooling and heating device to continue working, adjusting the environment from the current ambient temperature to the second temperature.
[0096] In step (23) above, the current ambient temperature of the environment is collected by a temperature sensor set in the environment. The temperature sensor can interact with the control unit, and then the temperature sensor can send the collected current ambient temperature to the control unit.
[0097] In step (24) above, the first temperature threshold is pre-stored in the control unit.
[0098] Optionally, in order to save energy consumption of the working cooling and heating device while accurately controlling the ambient temperature, the driving frequency of the spring clip material can be reduced. The above step (26) can also be performed in the following steps (27) to (31):
[0099] (27) Obtain the first driving frequency of the spring card material corresponding to the above-mentioned cooling and heating capacity;
[0100] (28) Based on the first driving frequency of the above-mentioned card material, the driving cycle of the above-mentioned card material is obtained, wherein a single driving cycle includes: loading time, first waiting time, unloading time and second waiting time;
[0101] (29) Obtain the first waiting time update value corresponding to the temperature difference between the current ambient temperature and the second temperature;
[0102] (30) Using the obtained first waiting time update value, the duration of the first waiting time and the second waiting time are incremented respectively, thereby extending the driving cycle of the card material.
[0103] (31) Control the spring material unit in the cooling and heating generator of the above-mentioned working cooling and heating device to continue to work according to the extended driving cycle of the above-mentioned spring material, and adjust the above-mentioned environment from the above-mentioned current ambient temperature to the above-mentioned second temperature.
[0104] In step (27) above, the control unit pre-stores the correspondence between the cooling capacity and the driving frequency of the spring card material.
[0105] The control unit can query and obtain the first driving frequency of the cartridge material corresponding to the cooling and heating capacity based on the correspondence between the cooling and heating capacity and the driving frequency of the cartridge material.
[0106] In step (29) above, the control unit pre-stores the correspondence between temperature difference values and waiting time update values.
[0107] The control unit can 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.
[0108] In step (30) above, extending the driving cycle of the aforementioned cartridge material means reducing the driving frequency of the cartridge material.
[0109] Optionally, precise temperature control of the ambient temperature can also be achieved by increasing / decreasing the number of spring-loaded material units in the working cooling and heating device. The above step (26) can also be followed by the following steps (32) to (37):
[0110] (32) Obtain the mass of the above-mentioned spring card material corresponding to the above-mentioned cooling and heating capacity;
[0111] (33) Based on the obtained mass of the above-mentioned spring clip material, determine the first quantity of spring clip material units working in the cooling and heating generator of the above-mentioned working cooling and heating device.
[0112] (34) Obtain the second quantity of spring card material units corresponding to the temperature difference between the current ambient temperature and the second temperature;
[0113] (35) Calculate the quantity difference between the first quantity and the second quantity mentioned above;
[0114] (36) When the above quantity difference is positive, the spring card material unit controlling the above quantity difference quantity stops working, so that the second number of spring card material units in the cooling and heating generator of the above working cooling and heating device continues to work, and adjusts the above environment from the above current ambient temperature to the above second temperature.
[0115] (37) When the above quantity difference is negative, the spring card material unit that controls the quantity difference starts to work, so that the second number of spring card material units in the cooling and heating generator of the above working cooling and heating device continue to work, and adjust the environment from the current ambient temperature to the second temperature.
[0116] In step (32) above, the mass of the spring card material corresponding to the cooling and heating capacity is the mass of the spring card material that can adjust the environment from the first temperature to the second temperature and generate the above-mentioned cooling and heating capacity during the operation of the working cooling and heating device.
[0117] When the control unit starts working on the cooling and heating device, it calculates the mass of the spring card material corresponding to the cooling and heating capacity, and then buffers the calculated mass of the spring card material corresponding to the cooling and heating capacity.
[0118] In step (33) above, the first quantity of cartridge material units is equal to the mass of cartridge material divided by the mass of a single cartridge material unit.
[0119] The control unit pre-buffers the mass of a single cartridge material unit. In step (34) above, the control unit pre-sets a correspondence between the temperature difference and the number of cartridge material units.
[0120] The control unit can obtain the second number of cartridge material units corresponding to the temperature difference between the current ambient temperature and the aforementioned second temperature from the correspondence between the temperature difference and the number of cartridge material units.
[0121] In addition to the troubleshooting and precise temperature control methods mentioned above, the control unit can also control the refrigeration and heating equipment through zoned temperature control.
[0122] If the environment in which the aforementioned refrigeration and heating equipment is located is divided into two different temperature control zones, then the two refrigeration and heating devices can be installed in the two different temperature control zones respectively.
[0123] In order to perform zoned temperature control on the refrigeration and heating equipment, the control method for the refrigeration and heating equipment proposed in this embodiment may further include the following steps (40) to (42):
[0124] (40) Obtain the required temperature adjustment instructions for each temperature adjustment region in different temperature adjustment regions, wherein the temperature adjustment instructions for each of the above temperature adjustment regions include: the current fifth temperature and the adjusted sixth temperature of each of the above temperature adjustment regions;
[0125] (41) Determine the cooling and heating capacity of each temperature regulation zone according to the current fifth temperature and the sixth temperature after temperature adjustment.
[0126] (42) Based on the determined cooling and heating capacity of each temperature regulation zone, the cooling and heating devices installed in each temperature regulation zone are controlled to regulate the temperature of each of the above-mentioned temperature regulation zones, thereby performing different temperature control on each temperature regulation zone.
[0127] In step (41) above, the temperature difference between the current fifth temperature and the adjusted sixth temperature of each temperature adjustment zone is used to determine the cooling capacity of each temperature adjustment zone from the pre-set correspondence between the temperature difference and the cooling capacity.
[0128] In step (42) above, in order to control the cooling and heating devices installed in each temperature regulation zone to adjust the temperature of each temperature regulation zone based on the determined cooling and heating capacity of each temperature regulation zone, the following steps (421) to (423) can be performed:
[0129] (421) Based on the determined cooling and heating capacity of each temperature regulation zone, the operating time corresponding to the cooling and heating capacity of each temperature regulation zone and the third driving frequency and mass of the spring clip material in the cooling and heating device in each temperature regulation zone are obtained.
[0130] (422) Based on the obtained mass of the above-mentioned spring clip material, determine the fifth number of spring clip material units that need to work in the cooling and heating generator of the cooling and heating device in each of the above-mentioned temperature regulation areas.
[0131] (423) Control the operation of the fifth number of spring material units in the cooling and heating generator in each of the above-mentioned temperature adjustment zones to adjust the environment from the fifth temperature to the sixth temperature.
[0132] In step (421) above, the running time corresponding to the cooling and heating capacity of each of the above temperature regulation zones is equal to the cooling and heating capacity of each temperature regulation zone divided by the cooling and heating power of the spring card material.
