The air conditioner may further include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005.

Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0058] Those skilled in the art can understand that Figure 1 the structure shown in the figure does not constitute a limitation on the air conditioner, and it may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements.

[0059] As Figure 1 shown, the memory 1005 regarded as a computer storage medium may include an operating system, a network communication module, a user interface module, and an air conditioner refrigeration program.

[0061] Based on the above hardware structure, an embodiment of the air conditioner refrigeration method of the present invention is proposed.

[0062] Referring to Figure 2 , Figure 2 which is a schematic flowchart of the first embodiment of the air conditioner refrigeration method of the present invention, the first embodiment of the air conditioner refrigeration method of the present invention is proposed.

[0063] In the first embodiment, the air conditioner refrigeration method is applied to an air conditioner, which includes: an indoor energy storage heat exchanger, an outdoor additional heat exchanger, and a circulation pump. The indoor energy storage heat exchanger is connected to the outdoor additional heat exchanger through the circulation pump;

[0064] The air conditioner refrigeration method includes the following steps:

[0065] Step S10: When the air conditioner is in the refrigeration mode, collect the current outdoor ambient temperature, and determine the current refrigeration condition according to the current outdoor ambient temperature.

[0066] It should be understood that the execution subject of this embodiment is the air conditioner, and this embodiment does not limit this.

[0067] It can be understood that collecting the current outdoor ambient temperature can be receiving the sensor information uploaded by a preset sensor and determining the current outdoor ambient temperature according to the sensor information. Among them, the preset sensor can be a temperature sensor pre-installed on the air conditioner by the manufacturer of the air conditioner, and this embodiment does not limit this.

[0068] It should be understood that determining the current refrigeration condition according to the current outdoor ambient temperature can be finding the current refrigeration condition corresponding to the current outdoor temperature in a preset condition table. Among them, the preset condition table contains the corresponding relationship between the current outdoor temperature and the current refrigeration condition, and the corresponding relationship between the current outdoor temperature and the current refrigeration condition can be pre-set by the manufacturer of the air conditioner, and this embodiment does not limit this.

[0069] Furthermore, in order to simplify the refrigeration condition judgment step and improve the reliability of the refrigeration condition detection result, the step of collecting the current outdoor ambient temperature and determining the current refrigeration condition according to the current outdoor ambient temperature when the air conditioner is in the refrigeration mode includes:

[0070] When the air conditioner is in the refrigeration mode, collect the current outdoor ambient temperature, judge whether the current outdoor ambient temperature is less than or equal to a preset energy storage start temperature to obtain a first judgment result, judge whether the current outdoor ambient temperature is greater than or equal to a preset heat exchange start temperature to obtain a second judgment result, and determine the current refrigeration condition according to the first judgment result and the second judgment result.

[0071] Step S20: When the current refrigeration condition is a high-temperature refrigeration condition, collect the current first indoor ambient temperature and obtain the current first air conditioner set temperature of the air conditioner.

[0072] It should be noted that the high-temperature refrigeration condition can be the condition corresponding to the air conditioner when the outdoor ambient temperature is lower than the preset heat exchange start temperature, and this embodiment does not limit this.

[0073] It can be understood that the air conditioner set temperature can be the operating temperature of the air conditioner pre-set by the user through the control panel of the air conditioner; it can also be the operating temperature of the air conditioner pre-set by the user through the remote control corresponding to the air conditioner; it can also be the operating temperature of the air conditioner pre-set by the user through the terminal device that has pre-established a communication connection with the air conditioner. This embodiment does not limit this.

[0074] In specific implementation, for example, the air conditioner set temperature can be the operating temperature of the air conditioner pre-set by the user through a smart phone that has pre-established a wireless connection with the air conditioner. For example, 26 °C.

[0075] Step S30: When the first indoor environmental temperature is greater than the first air conditioner set temperature, control the indoor energy storage heat exchanger of the air conditioner to release cold energy, and control the circulation pump to start, so that the cold energy released by the indoor energy storage heat exchanger enters the outdoor additional heat exchanger.

[0076] It should be understood that when the first indoor environmental temperature is greater than the first air conditioner set temperature, the air conditioner enters the strong mode.

[0077] In addition, for the sake of easy understanding, refer to Figure 3 For example: After the air conditioner enters the strong mode, control the indoor energy storage heat exchanger 4 to start, and start the circulation pump 6, so that the cold energy released by the indoor energy storage heat exchanger 4 enters the outdoor additional heat exchanger 3, so as to be able to cool the refrigerant in the outdoor additional heat exchanger 3, make the temperature of the refrigerant before throttling at high temperature equivalent to that at normal temperature, reduce the evaporation temperature, and increase the cooling capacity of the system.

[0078] Furthermore, in order to ensure that the indoor energy storage heat exchanger can provide sufficient cold energy, therefore, it is necessary to first judge whether the indoor energy storage heat exchanger is in a sufficient energy storage state. To solve the above problems, when the first indoor environmental temperature is greater than the first air conditioner set temperature, controlling the indoor energy storage heat exchanger of the air conditioner to release cold energy and controlling the circulation pump to start so that the cold energy released by the indoor energy storage heat exchanger enters the outdoor additional heat exchanger includes:

[0079] When the first indoor environmental temperature is greater than the first air conditioner set temperature, obtain the first energy storage temperature of the indoor energy storage heat exchanger of the air conditioner, judge whether the indoor energy storage heat exchanger is in a sufficient energy storage state according to the first energy storage temperature, and when the indoor energy storage heat exchanger is in a sufficient energy storage state, control the indoor energy storage heat exchanger of the air conditioner to release cold energy and control the circulation pump to start.

[0080] Step S40: Control the outdoor additional heat exchanger to start, so that the air conditioner performs refrigeration.

[0081] In addition, for the sake of easy understanding, refer to Figure 3For example: After the air conditioner enters the strong mode, the indoor energy storage heat exchanger 4 is controlled to be turned on, the third cut-off valve 10 is controlled to be closed, the fourth cut-off valve 11 is controlled to be opened, and the outdoor additional heat exchanger 3 is controlled to be turned on. The refrigerant that has exchanged heat in the condenser 2 then enters the outdoor additional heat exchanger 3, where the refrigerant continues to exchange heat, making the temperature of the refrigerant before throttling at high temperature equivalent to that at normal temperature, reducing the evaporation temperature, and increasing the cooling capacity of the system. After entering the strong mode, the circulation pump 6 can be turned on so that the cold energy released by the indoor energy storage heat exchanger 4 enters the outdoor additional heat exchanger 3, thereby being able to cool the refrigerant in the outdoor additional heat exchanger 3.

[0082] In a specific implementation, Figure 4 is a schematic diagram of cold energy circulation in the strong mode of an embodiment. The refrigerant can circulate along the solid line circulation route in Figure 4 , and the heat transfer medium can circulate along the dotted line circulation route in Figure 4 . After the air conditioner enters the strong mode, the third cut-off valve 10 is controlled to be closed, the fourth cut-off valve 11 is controlled to be opened, and the circulation pump 6 is not turned on. At this time, the refrigerant flows out from the compressor 1 and into the condenser 2. After one heat exchange in the condenser 2, it enters the outdoor additional heat exchanger 3 through the fourth cut-off valve 11. The refrigerant continues to exchange heat in the outdoor additional heat exchanger 3. Moreover, the heat transfer medium released by the indoor energy storage heat exchanger 4 can enter the outdoor additional heat exchanger 3 through the circulation pump 6 to further exchange heat with the refrigerant in the outdoor additional heat exchanger 3. Finally, the heat-exchanged refrigerant enters the evaporator 5 through the first cut-off valve 8 and the second cut-off valve 9 for refrigeration, so as to achieve the purpose of increasing the cooling capacity at high temperature.

[0083] In the first embodiment, the air conditioner refrigeration method is applied to an air conditioner, which includes an indoor energy storage heat exchanger, an outdoor additional heat exchanger, and a circulation pump. The indoor energy storage heat exchanger is connected to the outdoor additional heat exchanger through the circulation pump. The air conditioner refrigeration method includes: when the air conditioner is in the refrigeration mode, collecting the current outdoor ambient temperature, and determining the current refrigeration condition according to the current outdoor ambient temperature. When the current refrigeration condition is a high-temperature refrigeration condition, collecting the current first indoor ambient temperature, and obtaining the current first air conditioner set temperature of the air conditioner. When the first indoor ambient temperature is greater than the first air conditioner set temperature, controlling the indoor energy storage heat exchanger of the air conditioner to release cold energy, and controlling the circulation pump to start, so that the cold energy released by the indoor energy storage heat exchanger enters the outdoor additional heat exchanger, and controlling the outdoor additional heat exchanger to start, so that the air conditioner performs refrigeration. Compared with the existing method of directly exchanging heat between the outdoor heat exchanger side and the high-temperature outdoor air, in the present invention, by additionally setting an indoor energy storage heat exchanger, an outdoor additional heat exchanger, and a circulation pump, when the current refrigeration condition is a high-temperature refrigeration condition, the cold energy stored in the indoor energy storage heat exchanger can be introduced into the outdoor additional heat exchanger through the circulation pump, so that the air conditioner enters the strong mode for refrigeration, and the refrigeration capacity at high temperatures is improved.

[0084] Referring to Figure 5 , Figure 5 FIG. is a schematic flow chart of the second embodiment of the air conditioner refrigeration method of the present invention. Based on the above Figure 2 shown first embodiment, a second embodiment of the air conditioner refrigeration method of the present invention is proposed.

[0085] In the second embodiment, the step S10 includes:

[0086] Step S101: When the air conditioner is in the refrigeration mode, collect the current outdoor ambient temperature.

[0087] It should be understood that collecting the current outdoor ambient temperature may be receiving the sensor information uploaded by a preset sensor and determining the current outdoor ambient temperature according to the sensor information. Among them, the preset sensor may be a temperature sensor pre-installed on the air conditioner by the manufacturer of the air conditioner, and this embodiment does not limit this.

[0088] Step S102: Determine whether the current outdoor ambient temperature is less than or equal to a preset energy storage start temperature to obtain a first determination result.

[0089] It should be noted that the preset energy storage start temperature may be pre-set by the manufacturer of the air conditioner, and this embodiment does not limit this.

[0090] Step S103: Determine whether the current outdoor ambient temperature is greater than or equal to a preset heat exchange start temperature to obtain a second determination result.

[0091] It should be noted that the preset heat exchange start temperature can be pre-set by the air conditioner manufacturer, and this embodiment does not limit it.

[0092] Step S104: Determine the current refrigeration condition according to the first judgment result and the second judgment result.

[0093] It should be noted that the current refrigeration condition can include a low-temperature refrigeration condition, a conventional refrigeration condition, and a high-temperature refrigeration condition.

[0094] It can be understood that determining the current refrigeration condition according to the first judgment result and the second judgment result can be when the current outdoor ambient temperature is less than or equal to the preset energy storage start temperature, determining that the current refrigeration condition is a low-temperature refrigeration condition; when the current outdoor ambient temperature is greater than the preset energy storage start temperature and less than the preset heat exchange start temperature, determining that the current refrigeration condition is a conventional refrigeration condition; when the current outdoor ambient temperature is greater than or equal to the preset heat exchange start temperature, determining that the current refrigeration condition is a high-temperature refrigeration condition.

[0095] In the second embodiment, when the air conditioner is in the refrigeration mode, the current outdoor ambient temperature is collected, it is judged whether the current outdoor ambient temperature is less than or equal to the preset energy storage start temperature to obtain a first judgment result, it is judged whether the current outdoor ambient temperature is greater than or equal to the preset heat exchange start temperature to obtain a second judgment result, and the current refrigeration condition is determined according to the first judgment result and the second judgment result; in this embodiment, by comparing the current outdoor ambient temperature with the preset energy storage start temperature and the preset heat exchange start temperature, and determining the current refrigeration condition according to the comparison result, the refrigeration condition judgment steps can be simplified, and the reliability of the refrigeration condition detection result can be improved.

[0096] In the second embodiment, after step S10, it further includes:

[0097] Step S110: When the current refrigeration condition is a low-temperature refrigeration condition, collect the current second indoor ambient temperature and obtain the current second air conditioner set temperature of the air conditioner.

[0098] It should be noted that the low-temperature refrigeration condition can be the condition of the air conditioner when the outdoor ambient temperature is lower than the preset energy storage start temperature, and this embodiment does not limit it.

[0099] The air conditioner set temperature can be the air conditioner operating temperature pre-set by the user through the control panel of the air conditioner; it can also be the air conditioner operating temperature pre-set by the user through the remote control corresponding to the air conditioner; it can also be the air conditioner operating temperature pre-set by the user through the terminal device that has been pre-connected to the air conditioner for communication, and this embodiment does not limit it.

[0100] In a specific implementation, for example, the set temperature of the air conditioner can be the operating temperature of the air conditioner pre-set by the user through a smart phone that has been pre-connected to the air conditioner wirelessly. For example, it can be 26°C.

[0101] It should be understood that obtaining the current second set temperature of the air conditioner can be reading the current second set temperature of the air conditioner from a preset storage area. Among them, the preset storage area can be a storage area pre-set by the manufacturer of the air conditioner for storing temperature information.

[0102] Step S120: When the second indoor environmental temperature is lower than the second set temperature of the air conditioner, control the indoor energy storage heat exchanger of the air conditioner to store cold energy.

[0103] It should be understood that when the second indoor environmental temperature is greater than or equal to the second set temperature of the air conditioner, the air conditioner does not perform any action and operates in a normal mode.

[0104] It can be understood that when the second indoor environmental temperature is lower than the second set temperature of the air conditioner, the air conditioner operates in an energy storage mode

[0105] In addition, for the sake of easy understanding, refer to Figure 6 for an example: Figure 6 FIG. is a schematic diagram of the cold energy cycle in the energy storage mode of an embodiment. The refrigerant can circulate in the cycle loop according to the solid line cycle route in Figure 6 . After the air conditioner enters the energy storage mode, control the second cut-off valve 9 to open and the first cut-off valve 8 to close. At this time, the refrigerant flows out of the compressor 1, flows into the condenser 2, after a heat exchange in the condenser 2, flows into the indoor energy storage heat exchanger 4 through the second cut-off valve 9 for heat exchange, and then enters the evaporator 5 for heat exchange, so that a part of the cold energy can be stored in the indoor energy storage heat exchanger 4.

[0106] In the second embodiment, when the current refrigeration working condition is a low-temperature refrigeration working condition, collect the current second indoor environmental temperature, and obtain the current second set temperature of the air conditioner. When the second indoor environmental temperature is lower than the second set temperature of the air conditioner, control the indoor energy storage heat exchanger of the air conditioner to store cold energy, so that when the indoor environmental temperature is lower than the user-set temperature, the redundant refrigeration capacity of the system can be stored for subsequent refrigeration use.

[0107] In the second embodiment, the step S30 includes:

[0108] Step S301: When the first indoor environmental temperature is greater than the first set temperature of the air conditioner, obtain the first energy storage temperature of the indoor energy storage heat exchanger of the air conditioner.

[0109] It should be noted that the first energy storage temperature can be the internal temperature of the indoor energy storage heat exchanger, and this embodiment does not limit this.

[0110] It should be understood that obtaining the first energy storage temperature of the indoor energy storage heat exchanger of the air conditioner can be receiving the first energy storage temperature uploaded by a sensor installed on the indoor energy storage heat exchanger, and this embodiment does not limit this.

[0111] Step S302: Determine whether the indoor energy storage heat exchanger is in a sufficient energy storage state according to the first energy storage temperature.

[0112] It should be noted that the energy storage temperature can be the internal temperature of the energy storage device, and this embodiment does not limit this.

[0113] It should be understood that determining whether the indoor energy storage heat exchanger is in a sufficient energy storage state according to the first energy storage temperature can be obtaining the current first condenser outlet temperature, and determining whether the indoor energy storage heat exchanger is in a sufficient energy storage state according to the first energy storage temperature and the first condenser outlet temperature.

[0114] It should be understood that determining whether the indoor energy storage heat exchanger is in a sufficient energy storage state according to the first energy storage temperature and the first condenser outlet temperature can be determining a first temperature difference according to the first energy storage temperature and the first condenser outlet temperature. When the first temperature difference is greater than or equal to a preset temperature threshold, it is determined that the indoor energy storage heat exchanger is in a sufficient energy storage state; when the first temperature difference is less than the preset temperature threshold, it is determined that the indoor energy storage heat exchanger is not in a sufficient energy storage state. Among them, the preset temperature threshold can be pre-set by the manufacturer of the air conditioner, and this embodiment does not limit this.

[0115] Step S303: When the indoor energy storage heat exchanger is in a sufficient energy storage state, control the indoor energy storage heat exchanger of the air conditioner to release cold energy, and control the circulation pump to start.

[0116] In addition, for the sake of easy understanding, refer to Figure 3 For example: When the indoor energy storage heat exchanger is in a sufficient energy storage state, control the indoor energy storage heat exchanger 4 to start, and start the circulation pump 6, so that the cold energy released by the indoor energy storage heat exchanger 4 enters the outdoor additional heat exchanger 3, so as to be able to cool the refrigerant in the outdoor additional heat exchanger 3, make the temperature of the refrigerant before throttling at high temperature equivalent to that at normal temperature, reduce the evaporation temperature, and increase the cooling capacity of the system.

[0117] In the second embodiment, when the indoor environmental temperature in the first chamber is greater than the first air-conditioning set temperature, the first energy storage temperature of the indoor energy storage heat exchanger of the air conditioner is obtained, and whether the indoor energy storage heat exchanger is in a sufficient energy storage state is judged according to the first energy storage temperature. When the indoor energy storage heat exchanger is in a sufficient energy storage state, the air conditioner is controlled to release the cold energy stored in the indoor energy storage heat exchanger, and the circulation pump is controlled to start, so that when the indoor environmental temperature is greater than the user-set temperature, the cold energy stored in the indoor energy storage heat exchanger can be released to the outdoor additional heat exchanger to cool the refrigerant in the outdoor additional heat exchanger, thereby increasing the cooling capacity of the system.

[0118] Refer to Figure 7 , Figure 7 which is a schematic flowchart of the third embodiment of the refrigeration method of the air conditioner of the present invention. Based on the above Figure 5 shown second embodiment, the third embodiment of the refrigeration method of the air conditioner of the present invention is proposed.

[0119] In the third embodiment, after the step S120, the following steps are further included:

[0120] Step S130: Obtain the energy storage time of the indoor energy storage heat exchanger, and judge whether the energy storage time is equal to the preset operation time of the cold storage mode.

[0121] It should be noted that the preset operation time of the cold storage mode can be pre-set by the manufacturer of the air conditioner, and this embodiment does not limit this.

[0122] It should be understood that when obtaining the energy storage time of the indoor energy storage heat exchanger, timing can be started when controlling the indoor energy storage heat exchanger to store cold energy, and the timing time is used as the energy storage time.

[0123] It can be understood that when the energy storage time is less than the preset operation time of the cold storage mode, the indoor energy storage heat exchanger is controlled to continue storing cold energy.

[0124] Step S140: When the energy storage time is equal to the preset operation time of the cold storage mode, obtain the second energy storage temperature of the indoor energy storage heat exchanger.

[0125] It should be noted that the second energy storage temperature can be the internal temperature of the indoor energy storage heat exchanger, and this embodiment does not limit this.

[0126] Step S150: Judge whether the indoor energy storage heat exchanger has completed energy storage according to the second energy storage temperature.

[0127] It should be understood that determining whether the indoor energy storage heat exchanger is in a sufficient energy storage state according to the second energy storage temperature may be to obtain the current second condenser outlet temperature, and determine whether the indoor energy storage heat exchanger is in a sufficient energy storage state according to the second energy storage temperature and the second condenser outlet temperature.

[0128] It should be understood that determining whether the indoor energy storage heat exchanger is in a sufficient energy storage state according to the second energy storage temperature and the second condenser outlet temperature may be to determine a second temperature difference according to the second energy storage temperature and the second condenser outlet temperature. When the second temperature difference is greater than or equal to a preset temperature threshold, it is determined that the indoor energy storage heat exchanger is in a sufficient energy storage state; when the second temperature difference is less than the preset temperature threshold, it is determined that the indoor energy storage heat exchanger is not in a sufficient energy storage state. Among them, the preset temperature threshold can be pre-set by the manufacturer of the air conditioner, and this embodiment does not limit this.

[0129] Further, in order to ensure that when the indoor energy storage heat exchanger has not completed energy storage, the cold quantity continues to be stored. After the step S150, it further includes:

[0130] When the indoor energy storage heat exchanger has not completed energy storage, return to the step of collecting the current second indoor environment temperature and obtaining the current second air conditioner set temperature of the air conditioner until the indoor energy storage heat exchanger completes energy storage.

[0131] It should be understood that when the indoor energy storage heat exchanger has not completed energy storage, the current second indoor environment temperature is collected again, and when the second indoor environment temperature is less than the second air conditioner set temperature, the indoor energy storage heat exchanger of the air conditioner is controlled to store cold quantity until the indoor energy storage heat exchanger completes energy storage.

[0132] Step S160: When the indoor energy storage heat exchanger completes energy storage, control the indoor energy storage heat exchanger to close.

[0133] In addition, for the sake of easy understanding, refer to Figure 3For example: when the current refrigeration condition is a low-temperature refrigeration condition, control the third cut-off valve 10 to open, the fourth cut-off valve 11 to close, control the outdoor additional heat exchanger 3 to close, control the second cut-off valve 9 to open, the first cut-off valve 8 to close, and control the indoor energy storage heat exchanger 4 to start. By adjusting the frequency of the compressor 1 and the throttling intensity of the throttling component 7, make the refrigerant enter the indoor energy storage heat exchanger 4 at a temperature lower than the energy storage temperature Tc_1 of the indoor energy storage heat exchanger. The refrigerant first stores a part of the cold energy in the indoor energy storage heat exchanger 4, and then enters the evaporator 5 for heat exchange, and transfers the remaining cold energy to the indoor space. After the indoor energy storage heat exchanger 4 operates for the preset cold storage mode operation time ΔT2, compare the indoor environmental temperature T1 with the air conditioner set temperature Ts. If T1 is less than Ts, the indoor energy storage heat exchanger 4 remains open until the energy storage of the indoor energy storage heat exchanger 4 ends. If T1 is greater than Ts, close the indoor energy storage heat exchanger 4, and the air conditioner enters the normal mode operation.

[0134] In the third embodiment, by obtaining the energy storage time of the indoor energy storage heat exchanger and judging whether the energy storage time is equal to the preset cold storage mode operation time, and judging whether the indoor energy storage heat exchanger has completed energy storage according to the second energy storage temperature, when the indoor energy storage heat exchanger has completed energy storage, control the indoor energy storage heat exchanger to close; in this embodiment, by comparing the energy storage time and the energy storage temperature with the preset information, it is possible to ensure that the indoor energy storage heat exchanger has completed energy storage and close it in time.

[0135] Refer to Figure 8 , Figure 8 is a schematic flowchart of the fourth embodiment of the refrigeration method of the air conditioner of the present invention. Based on the first embodiment shown above Figure 2 a fourth embodiment of the refrigeration method of the air conditioner of the present invention is proposed.

[0136] In the fourth embodiment, after the step S40, it further includes:

[0137] Step S50: Obtain the cold energy release time of the indoor energy storage heat exchanger, and judge whether the cold energy release time is equal to the preset strong mode operation time.

[0138] It should be noted that the preset strong mode operation time can be preset by the manufacturer of the air conditioner, and this embodiment does not limit this.

[0139] It should be understood that when obtaining the cold energy release time of the indoor energy storage heat exchanger, timing can be started when controlling the indoor energy storage heat exchanger to release cold energy, and the timing time is used as the cold energy release time.

[0140] It can be understood that when the cold energy release time is less than the preset strong mode operation time, control the indoor energy storage heat exchanger of the air conditioner to continue to release cold energy.

[0141] Step S60: When the cold release time is equal to the preset strong mode operation time, return to the step of collecting the current first indoor environmental temperature and obtaining the current first air conditioner set temperature of the air conditioner until the first indoor environmental temperature is less than or equal to the first air conditioner set temperature.

[0142] It can be understood that when the cold release time is equal to the preset strong mode operation time, it is necessary to determine whether to continue to turn on the strong mode. Therefore, it is necessary to return to the step of collecting the current first indoor environmental temperature and obtaining the current first air conditioner set temperature of the air conditioner.

[0143] Step S70: When the first indoor environmental temperature is less than or equal to the first air conditioner set temperature, control the outdoor additional heat exchanger and the indoor energy storage heat exchanger to close.

[0144] In addition, for the sake of understanding, refer to Figure 3 For example: When the current refrigeration condition is a high-temperature refrigeration condition, control the indoor energy storage heat exchanger 4 to turn on, control the third cut-off valve 10 to close, the fourth cut-off valve 11 to turn on, and the outdoor additional heat exchanger 3 to turn on. The refrigerant that has exchanged heat through the condenser 2 then enters the outdoor additional heat exchanger 3, and the refrigerant continues to exchange heat in the outdoor additional heat exchanger 3, making the temperature of the refrigerant before throttling at high temperature equivalent to that at normal temperature, reducing the evaporation temperature, and increasing the refrigeration capacity of the system. After entering the strong mode, the system first determines whether the energy storage of the indoor energy storage heat exchanger 4 is sufficient. If the energy storage is sufficient, turn on the circulation pump 6 so that the cold released by the indoor energy storage heat exchanger 4 enters the outdoor additional heat exchanger 3, thereby being able to cool the refrigerant in the outdoor additional heat exchanger 3. After each operation for the preset strong mode operation time ΔT3, compare the size of the indoor environmental temperature T1 and the air conditioner set temperature Ts. If T1 is greater than Ts, the strong mode remains on until the energy storage of the indoor energy storage heat exchanger 4 is insufficient. If T1 is less than Ts, exit the strong mode, and the system enters the normal mode operation.

[0145] In the fourth embodiment, by obtaining the cold release time of the indoor energy storage heat exchanger and determining whether the cold release time is equal to the preset strong mode operation time, when the cold release time is equal to the preset strong mode operation time, return to the step of collecting the current first indoor environmental temperature and obtaining the current first air conditioner set temperature of the air conditioner until the first indoor environmental temperature is less than or equal to the first air conditioner set temperature. When the first indoor environmental temperature is less than or equal to the first air conditioner set temperature, control the outdoor additional heat exchanger and the indoor energy storage heat exchanger to close, thereby enabling the temperature of the refrigerant before throttling at high temperature to be equivalent to that at normal temperature, reducing the evaporation temperature, and increasing the refrigeration capacity of the system.

[0146] In addition, an embodiment of the present invention further provides a storage medium, on which an air conditioner refrigeration program is stored. When the air conditioner refrigeration program is executed by a processor, the steps of the air conditioner refrigeration method described above are implemented.

[0147] In addition, with reference to Figure 9 , an embodiment of the present invention further provides an air conditioner refrigeration device, which includes a determination module 10, an acquisition module 20, and a control module 30;

[0148] The determination module 10 is configured to collect the current outdoor ambient temperature when the air conditioner is in the refrigeration mode, and determine the current refrigeration condition according to the current outdoor ambient temperature.

[0149] It can be understood that collecting the current outdoor ambient temperature can be receiving the sensor information uploaded by a preset sensor and determining the current outdoor ambient temperature according to the sensor information. Among them, the preset sensor can be a temperature sensor pre-installed on the air conditioner by the manufacturer of the air conditioner, and this embodiment does not limit this.

[0150] It should be understood that determining the current refrigeration condition according to the current outdoor ambient temperature can be finding the current refrigeration condition corresponding to the current outdoor temperature in a preset condition table. Among them, the preset condition table contains the corresponding relationship between the current outdoor temperature and the current refrigeration condition, and the corresponding relationship between the current outdoor temperature and the current refrigeration condition can be pre-set by the manufacturer of the air conditioner, and this embodiment does not limit this.

[0151] Further, in order to simplify the refrigeration condition judgment step and improve the reliability of the refrigeration condition detection result, the determination module 10 is further configured to collect the current outdoor ambient temperature when the air conditioner is in the refrigeration mode, judge whether the current outdoor ambient temperature is less than or equal to a preset energy storage start temperature to obtain a first judgment result, judge whether the current outdoor ambient temperature is greater than or equal to a preset heat exchange start temperature to obtain a second judgment result, and determine the current refrigeration condition according to the first judgment result and the second judgment result.

[0152] The acquisition module 20 is configured to collect the current first indoor ambient temperature and obtain the current first air conditioner set temperature of the air conditioner when the current refrigeration condition is a high-temperature refrigeration condition.

[0153] It should be noted that the high-temperature refrigeration condition can be the condition corresponding to the air conditioner when the outdoor ambient temperature is lower than the preset heat exchange start temperature, and this embodiment does not limit this.

[0154] It can be understood that the air conditioner set temperature can be the air conditioner operating temperature pre-set by the user through the control panel of the air conditioner; it can also be the air conditioner operating temperature pre-set by the user through the remote control corresponding to the air conditioner; it can also be the air conditioner operating temperature pre-set by the user through the terminal device that has been pre-connected to the air conditioner for communication. This embodiment does not limit this.

[0155] In a specific implementation, for example, the air conditioner set temperature can be the air conditioner operating temperature pre-set by the user through a smart phone that has been pre-connected to the air conditioner wirelessly. For example, it is 26°C.

[0156] The control module 30 is used to control the indoor energy storage heat exchanger of the air conditioner to release cold when the first indoor environmental temperature is greater than the first air conditioner set temperature, and to control the circulation pump to start, so that the cold released by the indoor energy storage heat exchanger enters the outdoor additional heat exchanger.

[0157] It should be understood that when the first indoor environmental temperature is greater than the first air conditioner set temperature, the air conditioner enters the strong mode.

[0158] In addition, for the sake of easy understanding, refer to Figure 3 For example: after the air conditioner enters the strong mode, control the indoor energy storage heat exchanger 4 to start, and start the circulation pump 6, so that the cold released by the indoor energy storage heat exchanger 4 enters the outdoor additional heat exchanger 3, so as to be able to cool the refrigerant in the outdoor additional heat exchanger 3, make the temperature of the refrigerant before throttling at high temperature equivalent to that at normal temperature, reduce the evaporation temperature, and increase the cooling capacity of the system.

[0159] Furthermore, in order to ensure that the indoor energy storage heat exchanger can provide sufficient cold, it is necessary to first determine whether the indoor energy storage heat exchanger is in a sufficient energy storage state. To solve the above problems, the control module 30 is also used to obtain the first energy storage temperature of the indoor energy storage heat exchanger of the air conditioner when the first indoor environmental temperature is greater than the first air conditioner set temperature, judge whether the indoor energy storage heat exchanger is in a sufficient energy storage state according to the first energy storage temperature, and when the indoor energy storage heat exchanger is in a sufficient energy storage state, control the indoor energy storage heat exchanger of the air conditioner to release cold, and control the circulation pump to start.

[0160] The control module 30 is also used to control the outdoor additional heat exchanger to start, so that the air conditioner performs refrigeration.

[0161] In addition, for the sake of easy understanding, refer to Figure 3For example: after the air conditioner enters the strong mode, control the indoor energy storage heat exchanger 4 to start, control the third cut-off valve 10 to close, the fourth cut-off valve 11 to open, and the outdoor additional heat exchanger 3 to open. The refrigerant that has exchanged heat in the condenser 2 then enters the outdoor additional heat exchanger 3, where the refrigerant continues to exchange heat, making the temperature of the refrigerant before throttling at high temperature equivalent to that at normal temperature, reducing the evaporation temperature, and increasing the cooling capacity of the system. After entering the strong mode, the circulation pump 6 can be started so that the cold energy released by the indoor energy storage heat exchanger 4 enters the outdoor additional heat exchanger 3, thereby being able to cool the refrigerant in the outdoor additional heat exchanger 3.

[0162] In a specific implementation, Figure 4 is a schematic diagram of cold energy circulation in the strong mode of an embodiment. The refrigerant can circulate along the solid line circulation route in Figure 4 , and the heat carrier can circulate along the dotted line circulation route in Figure 4 . After the air conditioner enters the strong mode, control the third cut-off valve 10 to close, the fourth cut-off valve 11 to open, and the circulation pump 6 not to start. At this time, the refrigerant flows out of the compressor 1 and into the condenser 2. After one heat exchange in the condenser 2, it enters the outdoor additional heat exchanger 3 through the fourth cut-off valve 11. The refrigerant continues to exchange heat in the outdoor additional heat exchanger 3. Moreover, the heat carrier released by the indoor energy storage heat exchanger 4 can enter the outdoor additional heat exchanger 3 through the circulation pump 6 to further exchange heat with the refrigerant in the outdoor additional heat exchanger 3. Finally, the heat-exchanged refrigerant enters the evaporator 5 through the first cut-off valve 8 and the second cut-off valve 9 for refrigeration, so as to achieve the purpose of increasing the cooling capacity at high temperature.

[0163] In this embodiment, the air conditioner refrigeration method is applied to an air conditioner, which includes an indoor energy storage heat exchanger, an outdoor additional heat exchanger, and a circulation pump.

Compared with the existing method of directly exchanging heat between the outdoor heat exchanger side and the outdoor high-temperature air, in the present invention, by additionally setting an indoor energy storage heat exchanger, an outdoor additional heat exchanger, and a circulation pump, when the current refrigeration working condition is a high-temperature refrigeration working condition, the cold energy stored in the indoor energy storage heat exchanger can be introduced into the outdoor additional heat exchanger through the circulation pump, so that the air conditioner enters the strong mode for refrigeration and improves the refrigeration capacity at high temperatures.

[0164] In one embodiment, the control module 30 is further configured to, when the first indoor ambient temperature is greater than the first air conditioner set temperature, obtain the first energy storage temperature of the indoor energy storage heat exchanger of the air conditioner, determine whether the indoor energy storage heat exchanger is in a sufficient energy storage state according to the first energy storage temperature, and when the indoor energy storage heat exchanger is in a sufficient energy storage state, control the indoor energy storage heat exchanger of the air conditioner to release cold energy and control the circulation pump to start;

[0165] In one embodiment, the control module 30 is further configured to obtain the cold energy release time of the indoor energy storage heat exchanger and determine whether the cold energy release time is equal to the preset strong mode operation time. When the cold energy release time is equal to the preset strong mode operation time, return to the step of collecting the current first indoor ambient temperature and obtaining the current first air conditioner set temperature of the air conditioner until the first indoor ambient temperature is less than or equal to the first air conditioner set temperature. When the first indoor ambient temperature is less than or equal to the first air conditioner set temperature, control the outdoor additional heat exchanger and the indoor energy storage heat exchanger to close;

[0166] In one embodiment, the air conditioner refrigeration device further includes an energy storage module;

[0167] The energy storage module is configured to, when the current refrigeration working condition is a low-temperature refrigeration working condition, collect the current second indoor ambient temperature and obtain the current second air conditioner set temperature of the air conditioner, and when the second indoor ambient temperature is less than the second air conditioner set temperature, control the indoor energy storage heat exchanger of the air conditioner to store cold energy;
