[ 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 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 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.

upgrading from the current software version number O-100 to a software version number O-101; // upgrade policy
Configuring an upgrade package of a software version number O-101; // upgrade kit
Outdoor unit software 00-03';
upgrading from the current software version number O-999 to a software version number O-1001; // upgrade policy
Configuring an upgrade package of a software version number O-1001; // upgrade kit
Fourthly, indoor unit software 00-04;
upgrading from the current software version number I-100 to a software version number I-101; // upgrade policy
And configuring an upgrade package of the software version number I-101. // upgrade Package.
And carrying out strategy distribution on the APP side so as to be used for upgrading the equipment to be upgraded in order.
The policy allocation procedure on the APP side can be described as follows.
(1) And acquiring a device policy data List List taking a family as a unit from the APP user from the cloud platform.
The device measurement data List is specific to all devices to be upgraded (including indoor units, outdoor units, gateway devices, and networking line controllers) in a certain home.
The device policy data List at least includes: the Device identification Device _ FLG and the Device Type Device _ Type which represent each Device to be upgraded, the upgrade identification OTA _ FLG which represents whether each Device to be upgraded is to be upgraded and the upgrade strategy list.
List {
Device_FLG；
Device_Type；
OTA_FLG；
Upgrade policy List
An upgrade policy 1;
an upgrade policy 2;
......
}
}
the device identifier may be a device code or a binding code assigned to the device, such as a two-dimensional code.
Each device to be upgraded has a device code, similar to the device identification card, for distinguishing between different devices.
The Device Type Device _ Type identifies the Type of the Device, which may be a gateway Device, a networking cable manager, an indoor unit, or an outdoor unit, for example, the Device Type Device _ Type is labeled as Type 1, Type 2, Type 3, and Type 4, where Type 1 represents a gateway Device, Type 2 represents a networking cable manager, Type 3 represents an outdoor unit, and Type 4 represents an indoor unit.
Note that, with the gateway device represented by type 1, there may also be gateway devices of different device codes.
The upgrade identifier OTA _ FLG is 1 or 0, wherein 1, 1 indicates that the device is to be upgraded, and 0 indicates that the device is not upgraded.
The upgrade policy list refers to a container that receives the upgrade policies of the devices to be upgraded at the same time.
For example, upgrade policy 1 may be: the outdoor unit 00-04 is upgraded from the current software version number O-100 to the software version number O-101; upgrade policy 2 may be: the indoor unit software 00-04 is upgraded from the current software version number I-100 to the software version number I-101.
It should be noted that, acquiring the new software version number acquires the corresponding upgrade package.
The device policy data List may include a user confirmation identification Confirm _ FLG and a policy Type Strategy _ Type, in addition to those described above.
Each device to be upgraded has a user confirmation identity Confirm _ FLG, and the initial values can be respectively assigned to 0.
On the APP side, when the user selects to upgrade the device, assigning 1 to the user confirmation identifier Confirm _ FLG, and the user confirmation identifier Confirm _ FLG of the device that is not selected to be upgraded is still 0.
The policy Type Strategy _ Type is used to identify which device Type of upgrade policy.
The policy Type Strategy _ Type corresponds to the Device Type Device _ Type.
As described above, the Device Type Device _ Type includes a gateway Device, a networking line controller, an indoor unit, and an outdoor unit; correspondingly, the policy Type Strategy _ Type refers to an upgrade policy of the gateway device, the networking line controller, the indoor unit, and the outdoor unit.
If the current Device is a gateway Device, the Device Type Device _ Type is the gateway Device, and the corresponding policy Type Strategy _ Type represents an upgrade policy of the gateway Device.
As such, the device policy data List may also be represented as follows:
List{
Device_FLG；
Device_Type；
OTA_FLG；
upgrade policy List
An upgrade policy 1;
an upgrade policy 2;
......
}
Confirm_FLG；
Strategy_Type；
}
(2) and the APP side screens out the Device List Device _ List of each Device to be upgraded through the upgrade identification OTA _ FLG in the Device strategy data List List.
That is, the relevant content of the corresponding device of OTA _ FLG =0 is filtered out in the device policy data List, leaving the relevant content of each device to be upgraded (i.e., OTA _ FLG = 1).
Thus, the Device List has a policy identification OTA _ ID and a policy description OTA _ DESC in addition to the content (e.g., OTA _ FLG) filtered out of the Device policy data List.
Device_List{
OTA_FLG；
OTA_ID；
OTA_DESC；
}
The policy identification OTA _ ID refers to an identity used to identify the policy, e.g., the OTA _ ID of the gateway device is used to represent the policy of the gateway device and the OTA _ ID of the networking gatekeeper is used to represent the policy of the networking gatekeeper.
And determining the upgrading priority order of each device to be upgraded according to the OTA _ ID.
The policy description OTA _ DESC refers to a textual description of the policy content.
Each of the screened devices to be upgraded has a Device List Device _ List.
The Device List Device _ List may also include a user confirmation identification Confirm _ FLG, a policy Type Strategy _ Type, and a Popup identification Popup _ FLG.
The policy identification OTA _ ID and the policy Type Strategy _ Type also correspond to each other.
Each device to be upgraded has a Popup flag Popup _ FLG, and the initial values may be respectively assigned to 0.
At the APP side, if the pop-up prompts the indoor unit to be upgraded, the pop-up flag Popup _ FLG in the Device List Device _ List corresponding to the indoor unit is assigned (for example, to 1), otherwise, the initial value is maintained (for example, to 0).
As such, the Device List Device _ List may also be as follows:
Device_List{
OTA_FLG；
OTA_ID；
OTA_DESC；
Confirm_FLG；
Popup_FLG；
Strategy_Type；
}
when each device to be upgraded is upgraded, the windows are popped, so that a user can select whether to upgrade (for example, upgrade is not performed temporarily/upgrade is performed immediately), and the user experience is improved.
Certainly, the device to be upgraded can be upgraded in sequence according to the priority order by default without popping the window until the upgrade is finished.
(3) Traversing the Device List Device _ List, splicing the OTA _ DESC in the Device List Device _ List under different OTA _ IDs, and outputting a spliced policy document (namely, a text description of spliced policy contents).
For example, the Device List Device _ List1 for which indoor units exist is as follows:
Device_List1{
OTA _ FLG; // upgrade identification; for example, 1
OTA _ ID; // policy identification, e.g., 10000
OTA _ DESC; // policy description, e.g. indoor unit upgrade
}
For example, the Device List Device _ List2 for the presence gateway Device is as follows:
Device_List2 {
OTA _ FLG; // upgrade identification; for example, 1
OTA _ ID; // policy identification, e.g., 20000
OTA _ DESC; // policy description, e.g. gateway device upgrade
}
For example, the Device List Device _ List3 in which the outdoor units exist is as follows:
Device_List3{
OTA _ FLG; // upgrade identification; for example, 1
OTA _ ID; // policy identification, e.g., 30000
OTA _ DESC; // policy description, e.g. outdoor unit upgrade
}
Then, the splicing order of the device types (or policy types) is determined according to the policy identification OTA _ ID.
In the application, the OTA _ DESC in the Device List Device _ List are spliced according to different OTA _ IDs, namely according to the splicing sequence of the gateway Device- > networking line controller- > outdoor unit- > indoor unit.
Therefore, the strategy document spliced as above can output: (a) the software of the gateway device/the networking line controller/the outdoor unit/the indoor unit is upgrading, or the software of the gateway device/the outdoor unit/the indoor unit is upgrading; or the networked drive-by-wire/outdoor/indoor software is being upgraded, etc.
In addition, the policy document may also output: (b) suspending APP service in the upgrading process; (c) the upgrade process takes approximately N minutes, where N minutes is calculated, for example, from the time required for upgrading the gateway device/network cable controller/outdoor unit/indoor unit software.
(b) For alerting the user that the APP should not be operated during the device upgrade, (c) for feeding back to the user the time required for the upgrade so that the user can schedule the time appropriately.
Thus, for example, a policy document as described above may be expressed as follows:
(a) gateway device/networking line controller/outdoor unit/indoor unit software is upgrading;
(b) suspending APP service in the upgrading process;
(c) the upgrade process takes approximately N minutes.
(4) And outputting an upgrading interface and a strategy file of each device to be upgraded at the APP side, wherein the strategy file can be displayed in the upgrading interface.
The upgrading interface comprises an upgrading strategy and a strategy file of each device to be upgraded, and each device to be upgraded is provided with one upgrading interface.
And on the APP side, an upgrading interface for prompting upgrading of the equipment can be output according to the priority order in a window pop-up mode until all the equipment to be upgraded is upgraded.
For example, the outdoor unit is upgraded, and the upgrade interface may include the following:
00-03 of an outdoor unit;
the current version: o-100;
and (4) new version: o-101;
upgrading from the current software version number O-100 to a software version number O-101;
the strategy scheme.
And the upgrade interface includes the options "upgrade not on the fly" and "upgrade immediately".
And after the user clicks 'upgrade immediately', assigning a user confirmation identifier Confirm _ FLG (firmware _ flash) to upgrade the outdoor unit, otherwise, not upgrading the outdoor unit temporarily.
After the outdoor unit is upgraded, an upgrading interface for upgrading the indoor unit can be popped up, so that all the equipment to be upgraded are upgraded, and at the moment, the upgrading is finished.
The strategy of the equipment to be upgraded in the remote upgrading process can be configured through the WEB management platform, the flexibility is high, and the remote operation is convenient and fast; and then, the cloud platform is matched, the problem of strategy distribution during remote upgrading of equipment is solved at the APP side, ordered and active upgrading of each gateway device, the networking line controllers, the outdoor unit and the indoor unit is realized, the user software upgrading experience is improved, upgrading conflicts of each device are avoided, and reliable upgrading is realized.
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.
