The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the conditioned and heat exchanged air.
The compressor compresses 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 may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner may 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 function as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater of a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler of a cooling mode.
An air conditioner according to some embodiments of the present application includes an air conditioner indoor unit installed in an indoor space.

Specifically, the area information of the area where the air conditioner 10 is located may be written into the air conditioner remote controller when the air conditioner is shipped, and a key for transmitting the area information is provided on the air conditioner remote controller. After the user operates the air conditioner remote controller to perform the power-on operation of the air conditioner 10, a key for transmitting the area information may be pressed to transmit the area information to the controller 6, and the controller 6 may automatically determine the area where the user is located according to the received area information. The area information may be divided according to geographical location, country, etc., and may be divided into india, european union, north american mexico, etc., for example.

TABLE 1
| Target indoor temperature DEG C | Zone one (e.g. india) | Zone two (e.g. European Union) | Region three (e.g., north America mexico) |
| 28 | 40％ | - | - |
| 27 | 40％ | - | 40％ |
| 26 | 45％ | - | 40％ |
| 25 | 45％ | 60％ | 45％ |
| 24 | 50％ | 60％ | 45％ |
| 23 | 55％ | 60％ | 50％ |
| 22 | 55％ | 60％ | 55％ |
| 21 | 60％ | 60％ | 55％ |
| 20 | 65％ | - | 60％ |
| 19 | 70％ | - | 65％ |

For example, when the area where the user is located is determined to be the european union and the indoor temperature is determined to be 24 ℃, after table 1 is queried, it may be determined that the corresponding indoor humidity is obtained to be 60%, and then 60% is taken as the target indoor humidity. For another example, when it is determined that the user is in mexico in north america and the indoor temperature is 23 ℃, it may be determined that the corresponding indoor humidity is 50% after looking up table 1, and 50% is set as the target indoor humidity.
In some embodiments, the refrigerant circuit and the indoor fan 5 are controlled according to a target indoor temperature and a target indoor humidity. Specifically, after the new target indoor temperature and the new target indoor humidity are obtained, the new target indoor temperature and the new target indoor humidity are used as control parameters of the temperature and the humidity to control the operation state of the air conditioner 10, for example, the operation states of the refrigerant circuit and the indoor fan 5, so as to meet the requirements of users in the area on the temperature and the humidity, and improve the comfort level of the users.
According to the air conditioner 10 provided by the embodiment of the invention, when a user wants to change the default indoor temperature or the default indoor humidity, the user can directly send the first change instruction for changing the default indoor temperature without knowing the control logic of the temperature and the humidity set in each air conditioner 10, the air conditioner 10 can automatically acquire the target indoor temperature in response to the first change instruction, and automatically acquire the target indoor humidity corresponding to the target indoor temperature of the area where the air conditioner 10 is located according to the target indoor temperature according to the automatic inquiry area temperature and humidity table, so that the user can adaptively adjust the temperature and the humidity according to the operation of the user after the user adjusts the target indoor temperature even if the user is unfamiliar with the air conditioner product, and the user experience is improved.
In some embodiments of the present invention, the controller 6 is further configured to determine that the modified indoor temperature according to the first modification instruction is within the set temperature range, and to set the modified indoor temperature as the target indoor temperature.
For example, a temperature range may be set as needed or under laboratory conditions, and for example, a default indoor temperature ±3 ℃ when the air conditioner 10 is automatically operated in a certain mode, that is, [ default indoor temperature-3 ℃, default indoor temperature +3℃ ] may be used as the set temperature range. Here, the controller 6 confirms that the user is in the european union and that the default indoor temperature of the air conditioner 10 is 22 ℃, for example, and may further determine that the set temperature range is [18 ℃,25 ℃.
Further, when the user controls the air conditioner remote controller to send the first modification instruction to the air conditioner 10, the controller 6 determines that the indoor temperature modified by the user is 24 ℃ according to the first modification instruction, and further determines that the 24 ℃ is within the set temperature range [18 ℃,25 ℃ and directly uses the 24 ℃ as the target indoor temperature.
Or in other embodiments, determining that the indoor temperature modified according to the first modification instruction exceeds the upper temperature threshold of the set temperature range, and taking the upper temperature threshold as the target indoor temperature.
Specifically, taking the example in which the controller 6 in the above embodiment confirms that the area where the user is located is the european union, the default indoor temperature of the air conditioner 10 is 22 ℃ and the set temperature range is [18 ℃,25 ℃, if the controller 6 determines that the indoor temperature after the user modification is 28 ℃ according to the first modification instruction, and further determines that the 28 ℃ is not within the set temperature range [18 ℃,25 ℃, that is, the modified indoor temperature 28 ℃ exceeds the upper limit temperature threshold 25 ℃ of the set temperature range, the upper limit temperature threshold 25 ℃ is directly used as the target indoor temperature.
Or in other embodiments, it is determined that the indoor temperature modified according to the first modification instruction is lower than a lower temperature threshold of the set temperature range, and the lower temperature threshold is taken as the target indoor temperature.
Specifically, if the controller 6 determines that the indoor temperature after the user modification is 16 ℃ according to the first modification instruction, and further determines that the 16 ℃ is not within the set temperature range [18 ℃,25 ℃) i.e. the modified indoor temperature 16 ℃ exceeds the lower limit temperature threshold 18 ℃ of the set temperature range, the lower limit temperature threshold 18 ℃ is directly used as the target indoor temperature.
In some embodiments of the present invention, the controller 6 is further configured to receive a second change instruction for the default indoor humidity, determine that the indoor humidity changed according to the second change instruction is within the set humidity range, and use the changed indoor humidity as the target indoor humidity.
The air conditioner remote controller can be further provided with a humidity adjusting key, a user can operate the humidity adjusting key to set humidity so as to improve or reduce indoor humidity, and therefore the second changing instruction can be an instruction for changing default indoor humidity, and after the controller 6 receives the second changing instruction, the controller responds to the second changing instruction to obtain the corresponding target indoor humidity.
For example, still taking the example that the controller 6 in the above embodiment confirms that the area where the user is located is the european union, the humidity range may be set as required or under laboratory conditions, for example, [40%,80% ] may be used as the set humidity range. Further, when the user controls the air conditioner remote controller to send the second modification instruction to the air conditioner 10, the controller 6 determines that the indoor humidity after the user modification is 45% according to the second modification instruction, and further determines that 45% is located in the set humidity range [40%,80% ], and directly uses 45% as the target indoor humidity.
Or in other embodiments of the present invention, it is determined that the indoor humidity modified according to the second modification instruction exceeds the upper humidity threshold of the set humidity range, and the upper humidity threshold is used as the target indoor humidity.
Specifically, taking the example that the controller 6 in the above embodiment confirms that the area where the user is located is the european union and the set humidity range is [40%,80% ], if the controller 6 determines that the indoor humidity after the user modification is 85% according to the second modification instruction, and further determines that 85% is not within the set humidity range [40%,80% ], that is, the modified indoor humidity 85% exceeds the upper humidity threshold 80% of the set humidity range, the upper humidity threshold 80% is directly used as the target indoor humidity.
Or in other embodiments of the present invention, it is determined that the indoor humidity modified according to the first modification instruction exceeds the lower humidity threshold of the set humidity range, and the lower humidity threshold is taken as the target indoor humidity.
Specifically, if the controller 6 determines that the indoor humidity after the user modification is 25% according to the second modification instruction, and further determines that 25% is not within the set humidity range [40%,80% ], that is, the modified indoor humidity 25% exceeds the lower humidity threshold 80% of the set humidity range, the lower humidity threshold 40% is directly used as the target indoor humidity.
In some embodiments of the present invention, as shown in fig. 6, a block diagram of an air conditioner according to another embodiment of the present invention is shown, wherein the air conditioner 10 further includes a temperature sensor 7, specifically, the temperature sensor 7 may be disposed in an outdoor unit for collecting outdoor environment temperature in real time, and the temperature sensor 7 is connected to the controller 6 to upload the detected outdoor environment temperature into the controller 6.
