[ basic operation principle of air conditioner ]
A refrigeration cycle of an air conditioner includes 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 the heat is released to the ambient 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 an air conditioner refers to a portion including a compressor of a refrigeration cycle and includes an outdoor heat exchanger, the indoor unit of an air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit of an air conditioner.
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 for a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler for a cooling mode.

The central air conditioner comprises at least one outdoor unit, at least two indoor units, at least one wire controller, gateway equipment, a cloud platform and an APP side.

And each outdoor unit is in communication connection with each indoor unit through a communication bus.
Each outdoor unit and each indoor unit has its own address number.
One outdoor unit and a corresponding indoor unit form an air conditioning apparatus performing a function of conditioning air.
In the present application, the state of the air conditioner (i.e., the state of the indoor unit) may include a power on/off mode, a (cooling/heating/dehumidifying) mode, an air volume, and additional functions, which may include functions of energy saving, muting, sleeping, health, self-cleaning, forest wind, auxiliary heating, humidification, and the like.
The wire controller is used for controlling the indoor unit to work.
The wire controller can be a wireless wire controller (such as a WiFi wire controller) with a communication module, or a wired wire controller without a communication module.

For example, the 11# indoor unit has the following states: on/off, (cooling/heating/dehumidifying) mode, air volume, additional functions (energy saving, mute, sleep) are recorded as 11# state set.
The # 12 indoor unit has the following states: the on-off, (cooling/heating/dehumidifying) mode, air volume, additional functions (energy saving, mute, self-cleaning) are recorded as 12# state set.
At this time, the 1# line controller should display the on/off mode, (cooling/heating/dehumidifying) mode, the air volume, and additional functions (energy saving and mute).
The 21# indoor unit has the following states: the on/off, (cooling/heating/dehumidifying) mode, air volume, additional functions (energy saving, mute, sleep, health) are recorded as the 21# state set.
The 22# indoor unit has the following states: the on-off, (cooling/heating/dehumidifying) mode, air volume, additional functions (energy saving, silence, sleep, self-cleaning, forest wind) are recorded as the 22# state set.
The 23# indoor unit has the following states: on/off, (cooling/heating/dehumidifying) mode, air volume, additional functions (energy saving, silence, sleep, auxiliary heating, humidification) are recorded as 23# state set.
At this time, the 2# line controller should display the on/off mode, (cooling/heating/dehumidifying) mode, the air volume, and additional functions (energy saving, mute, sleep).
The gateway equipment is provided with a communication module, is not limited to communication in WiFi/NB-IOT modes and the like, and is used for reporting the state of the air conditioning equipment to the cloud platform.
The gateway device may be an NB-IOT adapter configured on the outdoor unit, and the NB-IOT adapter includes a main control chip and a communication chip connected to the main control chip.
The main control chip is used for acquiring the operation information of the internal and external units in the air conditioning system and transmitting the state change to the communication chip.
The communication chip is used for receiving the state change and feeding back the states of the internal and external units in the current air conditioning system to the cloud platform.
The gateway device may also be a WiFi gateway, which may be independent of the air conditioning system, connected to the communication bus, and capable of reporting the information related to the air conditioning system to the cloud platform.
And the cloud platform is interacted with the outdoor unit and the indoor unit through the gateway equipment.
In order to realize the control to air conditioning equipment through the APP side when a plurality of indoor sets of same drive-by-wire ware control, the cloud platform can calculate the intersection of the state of all indoor sets according to the drive-by-wire ware identification position of all drive-by-wire wares and the state of all indoor sets that each drive-by-wire ware is connected in this application to with APP side after-interaction, export at the APP side.

Therefore, the instruction of the control state of the APP side issued to the 1# wire controller can be responded by the 1# wire controller, and the purpose of controlling the central air conditioner through the APP is achieved.
The central air conditioning control system can not generate the problem that the wire controller is in centralized control by issuing a control instruction through the APP, and can not control the central air conditioner through the APP, so that the user experience is good.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
