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 high-temperature and high-pressure liquid-phase refrigerant 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 refrigerating effect by heat exchange 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 outdoor unit comprises an outdoor unit external storage unit, an outdoor main memory unit and an outdoor main memory unit, wherein the outdoor unit external storage unit is used for storing original outdoor unit operation data, the outdoor main memory unit is used for caching the outdoor unit operation data, the outdoor unit main memory unit is powered on every time, the main control unit of the outdoor unit calls the outdoor unit operation data from the outdoor unit external storage unit and caches the outdoor unit operation data to the outdoor main memory unit, and when the outdoor unit is controlled to operate, the main control unit directly calls the cached outdoor unit operation data from the outdoor main memory unit.
Fig. 1 is a flowchart illustrating a method for updating outdoor unit operation data according to an embodiment of the present invention, wherein the method for updating outdoor unit operation data is applied to an outdoor unit side, and includes at least steps S1-S3, as follows.
And S1, responding to the query instruction of the data stream number of the outdoor unit external storage unit, and feeding back the data stream number of the outdoor unit external storage unit, wherein the outdoor unit external storage unit is used for storing original outdoor unit operation data.
The outdoor unit external storage units are generally disposed on the circuit board, each outdoor unit external storage unit, such as an EEPROM, has a different data serial number, and the data serial numbers of the outdoor unit external storage units are written into the outdoor unit external storage units in a product development stage. The outdoor unit external storage units in the same batch or model can be identified through the data serial number.
In some embodiments of the present invention, an air conditioner update APP (Application) may be loaded on an upper computer, for example, a mobile terminal such as a tablet computer, a smart phone, or a desktop, and when an outdoor unit operation parameter needs to be updated, the outdoor unit operation parameter may be changed online by means of indoor and outdoor communication in a manner of upgrading an indoor unit program such as a mobile phone APP, where the outdoor unit operation parameter includes a motor parameter, a driving parameter, a system parameter, and the like of an outdoor unit.
Specifically, after the outdoor unit and the indoor unit establish communication, the indoor unit sends first frame data to the outdoor unit, the first frame data comprises a data stream number marker inquiry instruction for inquiring an external storage unit of the outdoor unit, the outdoor unit responds to the inquiry instruction of the data stream number of the external storage unit of the outdoor unit to execute OTA (over the air) upgrading of outdoor unit operation data, namely after the outdoor unit receives the first frame data sent by the indoor unit, the data stream number of the external storage unit of the outdoor unit is fed back to the indoor unit.
S2, an outdoor unit update packet is received.
In some embodiments of the present invention, the indoor unit determines whether there is a need for updating operation data of the outdoor unit, for example, whether an outdoor unit update data packet sent by an upper computer, for example, a mobile terminal, is received, if the indoor unit receives the outdoor unit update data packet, an inquiry command of a data stream number is sent, if the indoor unit receives the data stream number of an outdoor unit external storage unit, and determines that the outdoor unit matches according to the data stream number, an outdoor unit update data packet is sent to the outdoor unit, and if the outdoor unit receives the outdoor unit update data packet. The outdoor unit updating data packet is an OTA data packet, and the data packet comprises a storage address where outdoor unit operation data needing to be updated are located and data needing to be updated.
S3, the outdoor unit operation data in the data buffer area of the outdoor main memory unit is updated according to the outdoor unit update packet.
The main control unit calls the outdoor unit operation data from the outdoor unit external storage unit and caches the outdoor unit operation data into the outdoor main storage unit, and the response parameters are called from the outdoor main storage unit directly during operation.
Specifically, after the outdoor unit receives an outdoor unit update data packet, the outdoor unit obtains a target storage address and target operation data to be updated in the outdoor unit update data packet, and updates the outdoor unit operation data corresponding to the target storage address in the data cache region of the outdoor main memory unit to the target operation data, thereby updating the operation parameters of the outdoor unit. The outdoor unit only updates the outdoor unit operation data of the corresponding target address in the data cache region of the outdoor main memory unit, does not erase the actual operation chip storing the original outdoor unit operation parameters, namely the data in the outdoor unit external storage unit such as an EEPROM, and can ensure that the air conditioner can still call the original outdoor unit operation parameters from the outdoor unit external storage unit to ensure the normal operation of the outdoor unit when the updating fails or the updated data cannot be used.
After the outdoor unit updates the outdoor unit operating data in the data cache region of the outdoor main memory unit according to the outdoor unit update data packet, the outdoor unit needs to reply an OTA response mark to the indoor unit, wherein the OTA response mark can be represented by an appointed independent head code and a tail code.
The method for updating the running data of the outdoor unit is used for the outdoor unit, the outdoor unit receives the outdoor unit updating data packet, updates the running data of the outdoor unit in the data cache area of the outdoor main memory unit according to the outdoor unit updating data packet, does not erase the data in an actual running chip, namely an outdoor unit external storage unit, and can still run with the original running parameters when the updating fails or the updating data cannot be used. Through with the help of indoor outer communication, carry out OTA upgrading to off-premises station operating parameter, to the air conditioner that dispatches from the factory in batches, need not to return the factory or change outdoor control panel, adopt OTA's upgrading mode can realize the purpose of renewal off-premises station data, off-premises station operating parameter updates more convenient and with low costs.
