The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
Fig. 1 shows a circuit configuration of an air conditioner 1, and the air conditioner 1 includes a refrigerant circuit 10, and is capable of executing a vapor compression refrigeration cycle by circulating a refrigerant in the refrigerant circuit 10. The indoor unit 3 and the outdoor unit 2 are connected by a connecting pipe 4 to form a refrigerant circuit 10 in which a refrigerant circulates. The refrigerant circuit 10 includes a compressor 11, an outdoor heat exchanger 13, an expansion valve 14, an accumulator 15, and an indoor heat exchanger 16. Among them, the indoor heat exchanger 16 and the outdoor heat exchanger 13 operate as a condenser or an evaporator. The compressor 11 sucks the refrigerant from the suction port, and discharges the refrigerant compressed therein to the indoor heat exchanger 16 from the discharge port. The compressor 11 is an inverter compressor with variable capacity that performs rotational speed control by an inverter, and the four-way valve 12 switches between heating and cooling.
The outdoor heat exchanger 13 has a first inlet and a second outlet for allowing the refrigerant to flow between the refrigerant and the suction port of the compressor 11 through the accumulator 15, and the refrigerant flows between the refrigerant and the expansion valve 14. The outdoor heat exchanger 13 exchanges heat between the outdoor air and the refrigerant flowing through a heat transfer pipe (not shown) connected between the second inlet and the first inlet of the outdoor heat exchanger 13.
The expansion valve 14 is disposed between the outdoor heat exchanger 13 and the indoor heat exchanger 16. The expansion valve 14 has a function of expanding and decompressing the refrigerant flowing between the outdoor heat exchanger 13 and the indoor heat exchanger 16. The expansion valve 14 is configured to be capable of changing the opening degree, and by decreasing the opening degree, the flow path resistance of the refrigerant passing through the expansion valve 14 is increased, and by increasing the opening degree, the flow path resistance of the refrigerant passing through the expansion valve 14 is decreased. The expansion valve 14 expands and decompresses the refrigerant flowing from the indoor heat exchanger 16 to the outdoor heat exchanger 13 during the heating operation. Further, even if the states of other devices installed in the refrigerant circuit 10 do not change, when the opening degree of the expansion valve 14 changes, the flow rate of the refrigerant flowing in the refrigerant circuit 10 changes.
The indoor heat exchanger 16 has a second inlet and outlet for allowing the liquid refrigerant to flow between the expansion valve 14 and the indoor heat exchanger, and has a first inlet and outlet for allowing the gas refrigerant to flow between the compressor 11 and the discharge port. The indoor heat exchanger 16 exchanges heat between the refrigerant flowing through the heat transfer pipe connected between the second inlet and the first inlet and the second outlet of the indoor heat exchanger 16 and the indoor air.
An accumulator 15 is disposed between the outdoor heat exchanger 13 and the suction port of the compressor 11. In the accumulator 15, the refrigerant flowing from the outdoor heat exchanger 13 to the compressor 11 is separated into a gas refrigerant and a liquid refrigerant. Then, the gas refrigerant is mainly supplied from the accumulator 15 to the suction port of the compressor 11.
The outdoor unit 2 further includes an outdoor fan 21, and the outdoor fan 21 generates an airflow of outdoor air passing through the outdoor heat exchanger 13 to promote heat exchange between the refrigerant flowing through the heat transfer tubes and the outdoor air. The outdoor fan 21 is driven by an outdoor fan motor 21A capable of changing the rotation speed. The indoor unit 3 further includes an indoor fan 31, and the indoor fan 31 generates an airflow of the indoor air passing through the indoor heat exchanger 16 to promote heat exchange between the refrigerant flowing through the heat transfer tubes and the indoor air. The indoor fan 31 is driven by an indoor fan motor 31A whose rotation speed can be changed.
According to the embodiment of the invention, the controller of the air conditioner is configured to receive the query request sent by the server at the preset moment, the information to be compared of the air conditioner is returned to the server according to the query request, and the server compares the information to be compared with the upgrading information, and then receives the upgrading instruction to upgrade or receives the upgrading information to display to the user, so that OTA can be prevented from being carried out in batch, OTA upgrading can be carried out on a specific air conditioner independently, and user experience is improved.

And comparing the read air conditioner complete machine code with the complete machine code upgraded by the OTA, and judging whether the air conditioner complete machine code is in the complete machine code range upgraded by the OTA. The complete machine code of the OTA upgrade is a combination, and can be 1 or more or all complete machine codes. And when the whole machine code settings of the OTA upgrade are all 0, the OTA upgrade is considered to be a whole machine. And regarding the air conditioner which fails to read the whole machine code or does not accord with the coding rule, the air conditioner is not considered to be in the whole machine coding range of the OTA upgrading.
And judging the difference between the current OTA version information of the air conditioner and the current OTA version information. The OTA version information comprises a version number of a digital combination, and the OTA version is distinguished by comparing the size of the digital combination.
And step three, upgrading according to the comparison result.
If the current OTA version information accords with the whole machine coding range of the OTA upgrade and the first version number of the current OTA version information is lower than the second version number of the current OTA version information, pushing the OTA upgrade information to a user or forcibly carrying out the OTA upgrade; if the data is not matched with the data, OTA upgrading information is not pushed to the user, and if the importance of the software to be pushed corresponding to the OTA upgrading is higher, the OTA upgrading can be forced.

and if the indication information is the third indication information, the upgrading information is not sent to the controller any more.
And step four, determining an upgrading result.
And after the upgrading is finished, comparing OTA version information, if the current OTA version information is the same as the current OTA version information, upgrading successfully, and if the current OTA version information is different from the current OTA version information, upgrading fails.
And when the upgrading fails, the OTA interface prompts the user that the upgrading fails and pushes the OTA upgrading information again.
