The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic view of an air conditioner, the basic structure of which can be understood in conjunction with fig. 1, in which the air conditioner performs a cooling/heating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. Wherein the refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a 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 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 the 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.
An air conditioner according to some embodiments of the present application includes an air conditioner indoor unit installed in an indoor space. The indoor unit, which is an air conditioner, is connected to the outdoor unit, which is an air conditioner outdoor unit installed in an outdoor space, through a pipe. The outdoor unit of the air conditioner may be provided with a compressor, an outdoor heat exchanger, an outdoor fan, an expander, and similar components of a refrigeration cycle, and the indoor unit of the air conditioner may be provided with an indoor heat exchanger and an indoor fan.
In some embodiments of the present invention, fig. 2 is a block diagram of an air conditioner according to an embodiment of the present invention.
As shown in fig. 2, the air conditioner 10 includes a refrigerant circuit including a compressor 1, an indoor heat exchanger 2, a throttle valve 3, and an outdoor heat exchanger 4, and the air conditioner 10 further includes an indoor fan 5 and a controller 6. Wherein the indoor fan 5 is operated to supply air to the indoor heat exchanger 2.
The controller 6 is connected to the compressor 1 and the indoor fan 5, and is configured to control operation states of the compressor 1 and the indoor fan 5. Therein, the controller 6 of the embodiment of the present invention may be described in conjunction with fig. 3 and 4. Fig. 3 is a schematic view of an indoor unit of an air conditioner according to an embodiment of the present invention; FIG. 4 is a schematic diagram of a controller according to one embodiment of the invention. As shown in fig. 3, the controller 6 may be provided in the indoor unit of the air conditioner 10 shown in fig. 3 for receiving a signal from a user terminal, an air conditioner remote controller, or the like. As shown in fig. 4, the controller 6 may be a main control board with data processing and analyzing functions, wherein the main control board may include a monitoring unit, a determining unit, a control unit, and the like for processing and analyzing data.
The controller 6 is configured to: the area information and the operation mode setting information where the air conditioner 10 is located are acquired, and the corresponding default indoor temperature and default indoor humidity are acquired according to the area information and the operation mode setting information.
As shown in fig. 5, the air conditioner 10 may further include an air conditioner remote controller, which is a schematic diagram of an air conditioner remote controller according to an embodiment of the present invention, a user operates a key in the air conditioner remote controller to send signals such as a power-on instruction, area information, and a mode setting instruction to an indoor unit, and the air conditioner remote controller may be set as needed, which is not limited herein. The controller 6 can analyze and process the data to control the operation state of the air conditioner 10 after receiving the signal. 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, the user can press a key for sending the area information to send the area information to the controller 6, and the controller 6 can automatically judge the area where the user is located according to the received area information. The region information may be divided into regions according to geographical locations, countries, and the like, and the region may be divided into india, european union, and mexico in north america, for example.
Further, when the controller 6 determines the area where the air conditioner 10 is located according to the received area information, the controller may further control the air conditioner 10 to automatically operate a cooling mode, a heating mode, an air supply mode, and the like according to the environmental parameters of the area where the air conditioner is located, or a user may autonomously select an operation mode of the air conditioner 10 by operating an air conditioner remote controller. Furthermore, default indoor temperatures and default indoor humidities in different operation modes may be set in advance and stored in the controller 6, and when the controller 6 receives the operation mode setting information, the corresponding default indoor temperatures and default indoor humidities are directly obtained, and the air conditioner 10 is controlled to operate by using the default indoor temperatures and default indoor humidities as the target indoor temperatures and target indoor humidities.
For example, the air conditioner 10 is a product sold in the european union. When the air conditioner is delivered from a factory, the regional information of the European Union is written into the air conditioner remote controller, the main control board automatically judges that the region where the user is located is the European Union according to the remote control signal, the air conditioner enters a heating or air supply mode, and the default indoor temperature is 22 ℃.
In some embodiments, a first change instruction of the default indoor temperature is received, the default indoor temperature is changed according to the first change instruction, the target indoor temperature is obtained, a region temperature and humidity table is inquired according to the target indoor temperature and the region information to obtain the target indoor humidity, and the region temperature and humidity table is a corresponding data table of the region, the temperature and the humidity.
The air conditioner remote controller may further be provided with a temperature adjustment key, and a user may operate the temperature adjustment key to set the temperature so as to raise or lower the outlet air temperature of the air conditioner 10, so that the first change instruction may be an instruction for changing the default indoor temperature, and when the controller 6 receives the first change instruction, the controller obtains the appropriate target indoor temperature in response to the first change instruction.
Specifically, as shown in table 1, the regional temperature and humidity meter according to an embodiment of the present invention may be formed by detecting human body comfort in a large number of different regions and countries, or may be formed by querying different regional databases and performing weighted calculation according to characteristics of different data sources and user personality settings, and the regional temperature and humidity meter may be configured for environmental characteristics such as temperature and humidity of different regions, where in table 1, a region one is india, a region two is european union, and a region three is north america, for example. After the target indoor temperature and the area information are obtained, the target indoor temperature and the area information can be directly inquired in table 1 to obtain the corresponding target indoor humidity.

For example, when it is determined that the region where the user is located is the eu and it is determined that the indoor temperature is 24 ℃, after the table 1 is queried, it may be determined that the corresponding indoor humidity is obtained as 60%, and then 60% is used as the target indoor humidity. For another example, when it is determined that the region where the user is located is mexico in north america and the indoor temperature is 23 ℃, after referring to table 1, it may be determined that the corresponding indoor humidity is 50%, and 50% is taken 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 operating state of the air conditioner 10, for example, the operating states of the refrigerant circuit and the indoor fan 5, is controlled by using the new target indoor temperature and the target indoor humidity as the control parameters of the temperature and humidity, so as to meet the requirements of users in the area on the temperature and humidity, and improve the comfort of the users.
According to the air conditioner 10 provided in the embodiment of the present invention, when a user wants to change a default indoor temperature or a default indoor humidity, the user does not need to know a control logic for temperature and humidity set in each type of air conditioner 10, and can directly send a first change instruction for changing the default indoor temperature, and the air conditioner 10 can automatically obtain a target indoor temperature in response to the first change instruction, and automatically query a zone temperature and humidity table according to the target indoor temperature and humidity table to automatically obtain a target indoor humidity corresponding to the target indoor temperature of a zone where the air conditioner 10 is located.
In some embodiments of the present invention, the controller 6 is further configured to determine that the indoor temperature changed according to the first change instruction is within the set temperature range, and set the changed indoor temperature as the target indoor temperature.
For example, the temperature range may be set according to the requirement or under the laboratory condition, for example, the default indoor temperature ± 3 ℃ when the air conditioner 10 automatically operates in a certain mode, that is, [ default indoor temperature-3 ℃, default indoor temperature +3 ℃ ], may be used as the set temperature range. In the case where the controller 6 confirms that the region where the user is located is the eu and the default indoor temperature of the air conditioner 10 is 22 ℃, the set temperature range can be further determined to be [18 ℃,25 ℃).
Further, when the user operates the air conditioner remote controller to send a first change instruction to the air conditioner 10, the controller 6 determines that the indoor temperature changed by the user is 24 ℃ according to the first change instruction, and further determines that the 24 ℃ is within the set temperature range [18 ℃,25 ℃), and then directly takes the 24 ℃ as the target indoor temperature.
Alternatively, in other embodiments, it is determined that the indoor temperature after the modification according to the first modification instruction exceeds an upper limit temperature threshold of the set temperature range, and the upper limit temperature threshold is used as the target indoor temperature.
Specifically, also in the above embodiment, for example, if the controller 6 determines 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 ℃), the controller 6 determines that the indoor temperature after the user is changed is 28 ℃ according to the first change instruction, and further determines that the indoor temperature 28 ℃ is not within the set temperature range [18 ℃,25 ℃), that is, the indoor temperature after the change is 28 ℃ exceeding the upper limit temperature threshold of the set temperature range by 25 ℃, then directly takes the upper limit temperature threshold of 25 ℃ as the target indoor temperature.

Specifically, the area information of the area where the air conditioner 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 may be provided on the air conditioner remote controller. After the user operates the air conditioner remote controller to execute the starting operation of the air conditioner, the press key for sending the area information can be pressed to send the area information to the indoor unit, and the indoor unit can automatically judge the area where the user is located according to the received area information. The regional information may be divided into geographical locations, countries, and the like, and the region may be divided into india, european union, and mexico in north america, for example.
Furthermore, when the indoor unit determines the area of the air conditioner according to the received area information, the indoor unit can further control the air conditioner to automatically operate a cooling mode, a heating mode, an air supply mode and the like according to the environmental parameters of the area, or a user can also autonomously select the operation mode of the air conditioner by operating an air conditioner remote controller.
