In addition, in the drawings, structures with similar or identical structures are represented by the same reference numerals.

[0013] See also Figure 1 The present invention provides a combined refrigeration method, which is applied to an ice storage refrigeration system and is used to distribute the power supply of the ice storage refrigeration system to ensure the refrigeration capacity of the air conditioner. The combined refrigeration method includes S110-S120.

[0014] S110, controlled by a start-up instruction to start the ice storage refrigeration system, controlling the cold energy conduction component to be turned on so that the cold energy in the ice maker flows into the air conditioner through the cold energy conduction component, and confirming the power supply mode of the ice storage refrigeration system.

[0015] In an embodiment of the present invention, an ice storage refrigeration system may include an ice maker, an air conditioner, a power supply device, a cold energy conduction component and a control device, wherein the ice maker is used to make ice cubes and generate cold energy; the air conditioner is used for refrigeration; the power supply device is used to supply power to the ice maker and the air conditioner; the cold energy conduction component is used to connect the ice maker and the air conditioner so that the cold energy in the ice maker flows into the air conditioner; and the control device is used to distribute power to the ice maker and the air conditioner through the power supply device to ensure the refrigeration capacity of the air conditioner.

[0016] In the ice storage refrigeration system, the ice maker is in an automatic working state, that is, the ice maker automatically works according to its ice storage capacity. The ice storage capacity refers to the number of ice cubes stored in the ice maker. Generally speaking, when the ice storage capacity of the ice maker is lower than a certain level, the ice maker starts and makes ice cubes to increase the number of ice cubes and maintain the ice storage capacity of the ice maker near a standard value. When a start command is received, that is, when a command to start the air conditioner is received, the air conditioner starts, and the ice storage refrigeration system is in a working state. After the air conditioner is started, the power supply mode of the ice storage refrigeration system is confirmed.

[0017] The power supply mode may include a normal power supply mode and a standby power supply mode. The normal power supply mode refers to power supply by a normal power supply, and the standby power supply mode refers to power supply by a standby power supply, which may usually be a battery. When the ice storage refrigeration system starts to work, it indicates that the ice maker and the air conditioner are both in working state. At this time, the ice maker and the air conditioner are connected through the cold energy conduction component. It can be understood that when only the ice maker is in working state and the air conditioner is in the off state, the cold energy conduction component is in the off state, that is, the ice maker is not connected to the air conditioner.

[0018] When the ice maker and the air conditioner are in operation at the same time, the air conditioner is used for cooling to lower the temperature of the environment, and the ice maker is used for making ice cubes to provide cooling for the air conditioner. At this time, the ice maker and the air conditioner are connected through the cold energy conduction component, and the ice cubes in the ice maker exchange heat with the medium in the cold energy conduction component, thereby transferring the cooling energy of the ice cubes to the medium, and the medium in the cold energy conduction component then flows to the evaporator in the air conditioner and exchanges heat with the evaporator, thereby providing additional cooling energy for the air conditioner, lowering the temperature of the refrigerant in the air conditioner, and improving the cooling efficiency of the air conditioner.

[0019] S120: Allocate power to the ice maker and the air conditioner according to the power supply mode to compensate for the cooling capacity of the air conditioner.

[0020] In the embodiment of the present invention, the difference between different power supply modes mainly lies in the distribution of power supply. When there is sufficient power supply capacity, power can be distributed according to the rated power of the ice maker and the air conditioner. When power is insufficient, part of the power can be allocated to the ice maker on the premise of meeting the power supply demand of the air conditioner, so that the ice maker can make ice cubes. In extreme cases, all power can be allocated to the air conditioner to ensure that the air conditioner can cool normally. At this time, the ice maker does not work, but the ice maker and the air conditioner are still connected. The cold energy in the ice maker can still exchange heat with the cold energy conduction component, thereby reducing the temperature of the refrigerant in the air conditioner and improving the cooling capacity of the air conditioner.

[0021] See also Figure 2In some embodiments, such as in the present embodiment, the power supply mode includes a normal power supply mode and a standby power supply mode, and the step S120 may include steps S121-S122.

[0022] S121, if the power supply mode is the normal power supply mode, allocating power to the ice maker according to the rated power of the ice maker and allocating power to the air conditioner according to the rated power of the air conditioner; S122: If the power supply mode is the standby power supply mode, power is allocated to the ice maker according to the minimum operating power of the ice maker and power is allocated to the air conditioner according to the minimum operating power of the air conditioner.

[0023] In an embodiment of the present invention, the power supply mode may include a normal power supply mode and a backup power supply mode. The normal power supply mode means that the ice maker and the air conditioner are powered by a normal power supply, and the backup power supply mode means that the ice maker and the air conditioner are powered by a backup power supply.

[0024] In normal power supply mode, power is allocated to the ice maker and the air conditioner according to the rated power of the ice maker and the rated power of the air conditioner. At this time, the ice maker makes ice cubes normally, the air conditioner refrigerates normally, the ice maker is connected to the air conditioner, and the cold energy in the ice maker flows into the air conditioner through the cold energy conduction component, reducing the temperature of the refrigerant and improving the refrigeration capacity of the air conditioner.

[0025] In the backup power supply mode, the power can be allocated to the ice maker and the air conditioner according to the minimum operating power, and the power of the backup battery can be monitored in real time. When the power of the backup battery drops to a certain level, the ice maker can be turned off to extend the use time of the air conditioner. In the backup power supply mode, the ice maker and the air conditioner are still connected, and the cold energy can enter the air conditioner normally, thereby improving the cooling efficiency of the air conditioner. Even if the ice maker is turned off, the ice cubes stored in the ice maker can still continue to provide cold energy for the air conditioner.

[0026] See also Figure 3 In some embodiments, such as in the present embodiment, in the normal power supply mode, the method further includes step S130.

[0027] S130, obtaining the current indoor temperature, and adjusting the amount of cold energy from the ice maker flowing into the air conditioner through the cold energy conduction component according to the indoor temperature.

[0028] In the embodiment of the present invention, when the power supply mode is the normal power supply mode, the indoor temperature can be obtained, and the amount of cold that flows from the ice maker to the air conditioner can be adjusted according to the indoor temperature. For example, a throttle valve can be provided on the cold energy conduction component, and the amount of cold that flows into the cold energy conduction component can be adjusted through the throttle valve, thereby adjusting the amount of cold that enters the air conditioner.

[0029] See also Figure 4 In some embodiments, such as in the present embodiment, in the normal power supply mode, the step S130 also includes steps S131-S133.

[0030] S131, if the indoor temperature is greater than a first preset temperature threshold, adjusting the conduction degree of the cold energy conduction component so that all the cold energy generated by the ice maker flows into the air conditioner; S132, if the indoor temperature is less than or equal to the first preset temperature threshold and greater than a second preset temperature threshold, adjusting the conduction degree of the cold energy conduction component to allow a first preset percentage of cold energy to flow into the air conditioner; S133, if the indoor temperature is less than or equal to the second preset temperature threshold and greater than the third preset temperature threshold, adjusting the conduction degree of the cold energy conduction component to allow a second preset percentage of cold energy to flow into the air conditioner.

[0031] In the embodiment of the present invention, the first preset temperature threshold, the second preset temperature threshold and the third preset temperature threshold can all be empirical values, which can be determined by the specific types of the air conditioner and the ice maker. For example, the first preset temperature threshold can be 8°C, the second preset temperature threshold can be 5°C, and the third preset temperature threshold can be 3°C. When the indoor temperature is greater than 8°C, the throttle valve of the cold energy conduction component is fully opened, so that the cold in the ice maker can flow completely into the cold energy conduction component. When the indoor temperature is less than or equal to 8°C and greater than 5°C, the throttle valve of the cold energy conduction component is opened by 70%. When the indoor temperature is less than or equal to 5°C and greater than 3°C, the throttle valve of the cold energy conduction component is opened by 50%. When the indoor temperature is less than 3°C, the cold energy conduction component can be closed.

[0032] See also Figure 5 In some embodiments, such as in the present embodiment, in the normal power supply mode, the method further includes steps S140-S150.

[0033] S140, obtaining the current indoor temperature and the ice storage capacity of the ice maker; S150: If the indoor temperature is consistent with the cooling temperature set by the air conditioner and the ice storage amount is consistent with the preset ice storage amount, the ice storage refrigeration system is controlled to enter an energy-saving mode.

[0034] In the embodiment of the present invention, after the ice storage refrigeration system has been working for a period of time, the indoor temperature and the ice storage capacity of the ice maker are obtained. When the indoor temperature is the same as the set refrigeration temperature of the air conditioner and the ice storage capacity is the same as the preset ice storage capacity, the ice storage refrigeration system is controlled to enter the energy-saving mode. The set temperature of the air conditioner refers to the target temperature of the air conditioner, which is usually set by the user. For example, the refrigeration temperature of the air conditioner can be set to 26°C. The preset ice storage capacity is an empirical value, which is also set by the user. For example, the preset ice storage capacity can be 45kg. When the indoor temperature is 26°C and the ice storage capacity is 45kg, the energy-saving mode is entered.

[0035] In the energy-saving mode, the working cycle of the air conditioner is shortened, for example, the working cycle of the air conditioner is shortened from 30 minutes per hour to 15 minutes per hour. At the same time, the production frequency of the ice maker is reduced, for example, the ice maker produces ice cubes from 30 minutes per hour to 20 minutes per hour. In addition, the opening degree of the throttle valve of the cold energy conduction component can also be adjusted according to the indoor temperature and the ice storage capacity of the ice maker. For example, the opening degree of the throttle valve can be reduced to delay the consumption of ice cubes.

[0036] See also Figure 6 In some embodiments, such as in the present embodiment, in the normal power supply mode, the method further includes step S160.

[0037] S160: If it is detected that the power supply of the ice storage refrigeration system is abnormal, the power supply mode is switched to the backup power supply mode.

[0038] In the embodiment of the present invention, when the power supply is abnormal, for example, a power outage or power fluctuation occurs, the power supply mode can be switched from the normal power supply mode to the backup power supply mode.

[0039] See also Figure 7 In some embodiments, such as in the present embodiment, in the backup power supply mode, the method further includes steps S170-S180.

[0040] S170, obtaining the current indoor temperature and the cooling temperature set for the air conditioner; S180: If the difference between the indoor temperature and the cooling temperature is greater than a first preset threshold, the power supply of the ice storage refrigeration system is controlled to preferentially meet the power supply demand of the air conditioner.

[0041] In an embodiment of the present invention, in the standby power supply mode, the production frequency of the ice maker is reduced, the working cycle of the air conditioner is shortened, and the power is allocated according to the difference between the indoor temperature and the cooling temperature. For example, when the difference between the indoor temperature and the cooling temperature is greater than the first preset threshold, the power supply is controlled to give priority to meeting the power supply demand of the air conditioner, and the power supply can be a battery. The first preset threshold is an empirical value, which can be 5°C, that is, when the difference between the indoor temperature and the cooling temperature is greater than 5°C, the power supply is controlled to give priority to meeting the power supply demand of the air conditioner.

[0042] See also Figure 8 In some embodiments, such as in the present embodiment, in the backup power supply mode, the method further includes steps S1901-S1902.

[0043] S1901, obtaining the ice storage capacity of the ice maker; S1902: If the ice storage amount is less than a second preset threshold, control the power supply of the ice storage refrigeration system to preferentially meet the power supply demand of the ice maker.

[0044] In the embodiment of the present invention, in the standby power supply mode, when the ice storage amount is less than the second preset threshold, the power supply is controlled to preferentially meet the power supply demand of the ice maker. The second preset threshold is also an empirical value. For example, the second preset threshold may be one third of the total storage amount. Then, when the ice storage amount is less than one third of the total storage amount, the power supply preferentially meets the power supply demand of the ice maker.

[0045] In actual use, if the difference between the indoor temperature and the cooling temperature is greater than the first preset threshold and the ice storage amount is lower than the second preset threshold, the power supply demand of the air conditioner can be prioritized. After the power supply demand of the air conditioner is met, the power can be allocated to the ice maker.

[0046] See also Fig. 9 In some embodiments, such as in the present embodiment, in the backup power supply mode, the method further includes step S1903.

[0047] S1903: If an abnormality is detected in the ice maker or the air conditioner, an alarm message is output.

[0048] In an embodiment of the present invention, when an abnormality is detected in an ice maker or an air conditioner, an alarm message can be output to remind the user. For example, the temperature of the air conditioner is abnormal, and the ice storage of the ice maker is overweight. In addition, the ice storage refrigeration system can also be provided with an intelligent adjustment mode. In the intelligent adjustment mode, the ice storage refrigeration system performs self-learning and adjustment according to historical data and user habits. Collect data such as temperature, user demand for a certain appliance, and frequency of use. For example, according to the user's living habits, when going out to work in the morning and returning home in the evening, the operating time periods of the air conditioner and the ice maker are automatically adjusted to clarify whether the operating mode is cooling priority or ice storage priority within a certain time period.

[0049] See also Fig.10 The present invention also provides an ice storage refrigeration system, which includes an ice maker 100, an air conditioner 200, a power supply device 300, a cold energy conduction component 400 and a control device 500; the ice maker 100 is used to make ice cubes and generate cold energy; the air conditioner 200 is used for refrigeration; the power supply device 300 is used to supply power to the ice maker 100, the air conditioner 200, the cold energy conduction component 400 and the control device 500; the cold energy conduction component 400 is used to connect the ice maker 100 and the air conditioner 200 so that the cold energy in the ice maker 100 flows indirectly into the air conditioner 200; the control device 500 is used to distribute power to the ice maker 100 and the air conditioner 200 through the power supply device 300 to ensure the refrigeration capacity of the air conditioner 200.

[0050] Specifically, the air conditioner 200 may include an evaporator 210, a condenser 220, a throttling device and a compressor, and the above four devices constitute a refrigeration cycle. When the air conditioner 200 is in a closed state, the refrigerant is stored in the system in a liquid state. After the air conditioner 200 is turned on, the low-temperature, low-pressure gaseous refrigerant is sucked into the compressor from the liquid storage tank through the suction pipe. In the compressor, the refrigerant is compressed and becomes a high-temperature, high-pressure gaseous refrigerant, which enters the condenser 220 through the exhaust pipe. In the condenser 220, the refrigerant exchanges heat with the outside air and condenses into a high-pressure liquid refrigerant after releasing heat. The high-pressure liquid refrigerant passes through the throttling device, and the pressure is rapidly reduced, and the refrigerant becomes a low-pressure mixed state (mainly liquid, partly gaseous). The low-pressure and low-temperature refrigerant enters the evaporator 210 of the indoor unit, absorbs the heat of the indoor air in the evaporator 210, and evaporates into a low-pressure gaseous refrigerant, thereby reducing the temperature of the indoor air. At this time, the evaporator 210 acts as a heat exchanger. The low-pressure gaseous refrigerant returns to the compressor through the suction pipe and enters the next refrigeration cycle.

[0051] The ice maker 100 may include an ice storage module and an ice use module. The ice storage module may use polyurethane foam or other high-efficiency insulating materials to reduce the loss of coldness of ice cubes, and the ice use module may use water for users. When the power supply is normal, the ice maker 100 generates ice cubes. When the ice use module meets the user's use needs, the ice cubes in the ice storage module on the other side can also indirectly transfer coldness to the evaporator 210 of the air conditioner 200 through the cold energy conduction component 400. For example, multiple compartments such as ice storage modules and ice use modules may be provided in the ice maker 100, the former is used to place edible ice cubes, and the latter is used to place inedible ice cubes to provide energy for the air conditioner 200.

[0052] The cold energy conduction component 400 penetrates the inner wall of the ice maker 100 and is provided with a medium therein, which may be an ethylene glycol aqueous solution, a methanol aqueous solution or a specially designed low-temperature medium, and can absorb heat in a low-temperature environment and transfer it to the evaporator 210 .

[0053] The power supply device 300 may include a normal power supply 310 and a backup power supply 320. The backup power supply 320 may be a battery. When the normal power supply 310 is normal, the normal power supply 310 supplies power to the ice storage refrigeration system. When the normal power supply 310 is abnormal, the backup power supply 320 supplies power. The backup power supply 320 may be a battery.

[0054] The control device 500 is mainly used to receive data sent by the ice maker 100, the air conditioner 200 and various sensors, and allocate power to the ice maker 100 and the air conditioner 200 according to the power situation to ensure that the air conditioner 200 can cool normally.

[0055] In actual use, in the normal power supply mode, power is allocated to the ice maker 100 and the air conditioner 200 respectively according to the rated power of the ice maker 100 and the rated power of the air conditioner 200. At this time, the ice maker 100 makes ice cubes normally, the air conditioner 200 refrigerates normally, the ice maker 100 is connected with the air conditioner 200, and the cold energy in the ice maker 100 flows into the air conditioner 200 through the cold energy conduction component 400, reducing the temperature of the refrigerant and improving the refrigeration power of the air conditioner 200.

[0056] In the standby power supply mode, the power can be allocated to the ice maker 100 and the air conditioner 200 according to the minimum operating power, and the power of the standby battery can be monitored in real time. When the power of the standby battery is reduced to a certain level, the power supply to the ice maker 100 can be turned off to extend the use time of the air conditioner 200. In the standby power supply mode, the ice maker 100 and the air conditioner 200 are still in a connected state, and the cold energy can enter the air conditioner 200 normally, thereby improving the refrigeration efficiency of the air conditioner 200, and even if the ice maker 100 is in a closed state, the ice cubes stored in the ice maker 100 can still continue to provide cold energy for the air conditioner 200. At the same time, in this mode, the production frequency of the ice maker 100 is reduced, the working cycle of the air conditioner 200 is shortened, and the power is allocated according to the difference between the indoor temperature and the refrigeration temperature. For example, when the difference between the indoor temperature and the refrigeration temperature is greater than the first preset threshold, the power supply is controlled to give priority to meeting the power supply demand of the air conditioner 200, and the power supply can be a battery. The first preset threshold is an empirical value, which may be 5°C, that is, when the difference between the indoor temperature and the cooling temperature is greater than 5°C, the power supply is controlled to preferentially meet the power supply demand of the air conditioner 200. When the ice storage amount is less than the second preset threshold, the power supply is controlled to preferentially meet the power supply demand of the ice maker 100. The second preset threshold is also an empirical value, for example, the second preset threshold may be one third of the total storage amount, then when the ice storage amount is less than one third of the total storage amount, the power supply preferentially meets the power supply demand of the ice maker 100.

[0057] The combined refrigeration method and ice storage refrigeration system disclosed in the present invention can not only allocate electricity to the ice maker and the air conditioner according to the power supply mode, but also allocate the cooling capacity generated by the ice maker to the air conditioner, thereby ensuring the refrigeration capacity of the air conditioner and improving the refrigeration efficiency.

[0058] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
