Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.
In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
To further describe the solution of the present application, as shown in fig. 2, a schematic structural diagram of an air conditioner provided in the embodiment of the present application is specifically:
the refrigerant circulation circuit 101 circulates a refrigerant in a circuit including a compressor, a condenser, an expansion valve, an evaporator, a four-way valve, and a pressure reducer.
In a preferred embodiment of the present application, an air conditioner performs a refrigeration cycle of the air conditioner by using 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 102 is configured to compress a low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure refrigerant gas, and discharge the high-temperature and high-pressure refrigerant gas to the condenser.
In a preferred embodiment of the present application, 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 indoor heat exchanger 103 operates as a condenser or an evaporator.
In a preferred embodiment of the present application, the outdoor unit of the air conditioner includes 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 either the indoor unit or the outdoor unit.
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 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.
A fresh air fan 104 for providing outdoor fresh air to the indoor space;
a remote controller 105 mounted with a carbon dioxide sensor for detecting a carbon dioxide concentration around the remote controller;
most users are used to place the remote controller in a range which is easy to contact with the remote controller, the carbon dioxide sensor is installed on the remote controller, air volume control is carried out on the fresh air fan according to the detection value of the carbon dioxide sensor on the remote controller, and the exchanged fresh air is closest to the ideal state of the users. Meanwhile, due to the characteristic that the position of the remote controller is not fixed, the monitoring of the carbon dioxide concentration conditions at different positions in a room is facilitated.
The controller 106 is configured to determine whether the remote controller is indoors according to a distance between the remote controller and the controller;
if the remote controller is indoors, the carbon dioxide concentration detected by the remote controller is used as the indoor carbon dioxide concentration, and the operation of the fresh air fan is controlled based on the indoor carbon dioxide concentration and the operation state of the fresh air fan;
and if the remote controller is not indoors, controlling the fresh air fan to operate based on a default operation mode.
In a specific implementation scenario, it is considered that a user may take the remote controller out of a room to be monitored, and whether the remote controller is indoors needs to be judged to ensure that the concentration of carbon dioxide detected by the remote controller is effective data, and whether the remote controller is indoors can be judged through a straight-line distance between the remote controller and the controller. Because the remote controller is provided with the carbon dioxide sensor, the carbon dioxide concentration needs to be fed back to the controller once at intervals (such as 30s), and the remote controller and the controller need to be connected in a Bluetooth communication mode or a wireless communication mode and the like to transmit information. Therefore, the linear distance between the remote controller and the controller can be determined based on the signal strength or the positioning mode, and whether the remote controller is indoors or not can be judged by comparing the linear distance with the preset distance. The preset distance may have a factory default value (e.g., 3m), and the user may also specifically set the preset distance according to the use environment, and the setting mode may be set by a remote controller, application software corresponding to the mobile terminal, or an operation panel of the air conditioner.
When the distance between the remote controller and the controller does not exceed the preset distance, the remote controller is judged to be indoors, the carbon dioxide concentration detected by the remote controller is the carbon dioxide concentration closest to the actual feeling of a user, and the carbon dioxide concentration is used as the indoor carbon dioxide concentration to control the fresh air fan.
When the distance between the remote controller and the controller exceeds the preset distance, the remote controller is judged to be outdoors, the reference value of the carbon dioxide concentration detected by the remote controller is low, and the fresh air fan can be directly controlled according to a default operation mode. The default operation mode is specifically that when the fresh air fan is in an automatic air state, the air volume of the fresh air fan is controlled to operate according to high-medium-low-medium-high circulation, and each gear of rotating speed is operated for a period of time (such as 10 min); when the fresh air fan is in an un-started state, no action is performed. If when the carbon dioxide sensor breaks down in the remote controller, the concentration of carbon dioxide can not be detected, and the fresh air fan can be directly controlled according to a default operation mode. It should be noted that the default operation mode is only a preferred scheme provided in this embodiment, and the specific implementation content is not limited thereto. In order to confirm that the remote controller is not indoors, a confirmation message can be sent to the user to remind the user to judge whether the remote controller is in a room to be monitored. Judging the position of the remote controller according to the user confirmation instruction; and if the user does not reply any instruction after a period of time, judging that the remote controller is outdoors.
In order to accurately detect the indoor carbon dioxide concentration, in a preferred embodiment of the present application, the air conditioner further includes a fixed carbon dioxide sensor fixedly installed indoors for detecting the surrounding carbon dioxide concentration, and the controller is further configured to:
and if the remote controller is not indoors, taking the concentration of the carbon dioxide detected by the fixed carbon dioxide sensor as the indoor carbon dioxide concentration, and controlling the operation of the fresh air fan based on the indoor carbon dioxide concentration and the operation state of the fresh air fan.
In a specific implementation scenario, the fixed carbon dioxide sensor may be installed at any indoor location, including but not limited to the body of an indoor unit of an air conditioner, indoor furniture, and other indoor appliances. For example, the air conditioner.
When the remote controller is not indoors, the carbon dioxide concentration detected by the remote controller lacks effectiveness and cannot represent the indoor carbon dioxide concentration, the fresh air fan is controlled according to the default operation mode, the fresh air fan cannot be adjusted according to the indoor carbon dioxide concentration, and poor experience feeling is easily caused for a user. The carbon dioxide concentration detected by the fixed carbon dioxide sensor is used as indoor carbon dioxide concentration to control the fresh air fan, and optimal fresh air volume can be provided under the condition.
It should be noted that the above solution of the preferred embodiment is only one specific implementation solution proposed in the present application, and other ways of detecting the indoor carbon dioxide concentration when the remote controller is not indoors are all within the protection scope of the present application.
In order to better control the operation of the fresh air fan, in a preferred embodiment of the present application, the controller is specifically configured to:
if the fresh air fan is in an automatic air state, controlling the fresh air volume of the fresh air fan based on the indoor carbon dioxide concentration;
if the fresh air fan is in a manual air state, controlling the fresh air volume of the fresh air fan based on an operation instruction of a user;
and if the fresh air fan is in an un-started state, controlling the fresh air fan to start and operate based on the indoor carbon dioxide concentration and a starting instruction sent by a user.
In a specific implementation scene, the fresh air fan has multiple running states, including a starting state and an un-starting state, wherein the starting state further includes an automatic wind state and a manual wind state. When the fresh air fan is in an automatic air state, the fresh air quantity can be automatically adjusted based on the concentration of carbon dioxide, and the most comfortable air environment is provided for users. The fresh air fan in the manual air state can only control the fresh air volume of the fresh air fan according to the operation instruction of a user, and does not have an automatic adjusting function. If a user manually inputs a low wind instruction, the fresh air fan only operates in a low wind volume mode all the time. When the fresh air fan is in an un-started state, the concentration of carbon dioxide in a room can be monitored in real time, and the fresh air fan is controlled to be started automatically according to a starting instruction sent by a user.
In order to more accurately adjust the fresh air volume based on the carbon dioxide concentration, in a preferred embodiment of the present application, the fresh air blower is in an automatic air state, and the controller is specifically configured to:
if the indoor carbon dioxide concentration is smaller than a first threshold value, controlling the fresh air fan to operate in a low air volume mode;
if the indoor carbon dioxide concentration is greater than a second threshold value, controlling the fresh air fan to operate in a high air volume mode;
and if the indoor carbon dioxide concentration is greater than or equal to the first threshold value and less than or equal to the second threshold value, controlling the fresh air fan to operate in a medium air volume mode.
In a specific implementation scene, the carbon dioxide concentration is divided into a plurality of intervals corresponding to the fresh air volume grades, and the air volume mode corresponding to the operation of the fresh air fan is controlled according to the fresh air volume grades of the intervals corresponding to the carbon dioxide concentration. Generally, the indoor carbon dioxide concentration is low, the indoor air quality is good, in order to save energy and improve the user experience, excessive fresh air does not need to be provided, and only the low air volume mode is operated; the corresponding indoor carbon dioxide concentration is higher, the indoor air quality is poorer, and fresh air needs to be supplemented indoors urgently, so that the high-air-volume mode is operated. The first threshold is smaller than the second threshold, and the specific threshold setting can be specifically set according to the specific implementation scenario.
In order to control the fresh air fan to start and operate when appropriate, in a preferred embodiment of the present application, the fresh air fan is in an un-started state, and the controller is specifically configured to:
when the indoor carbon dioxide concentration exceeds a third threshold value, sending reminding information to a user and receiving a starting instruction sent by the user;
if the starting instruction is a starting instruction, controlling the fresh air fan to start and operate;
if the starting instruction is a closing instruction, reminding information is not sent to a user within a preset first time;
and if the starting instruction is not received within the preset second time, controlling the fresh air fan to start and operate.
In a specific implementation scene, when the fresh air fan is not started, the indoor carbon dioxide concentration can rise. When the concentration exceeds a set third threshold, the indoor carbon dioxide concentration exceeds the standard, and the user experience is influenced. At the moment, the controller sends reminding information to the user to remind the user to start the fresh air fan and collect outdoor fresh air. The specific reminding information can be sent to mobile terminal application software, a remote controller, an air conditioner control panel and the like, when a user receives the reminding information, the user can select a corresponding starting instruction to control the operation of the fresh air fan, select an opening instruction to control the start operation of the fresh air fan, and select a closing instruction to not send the reminding information to the user again within a period of time. When the user is asleep or otherwise cannot receive the reminding message and does not send any instruction, the controller can control the fresh air fan to start and operate by default after a period of time. The preset first time, the preset second time and the third threshold value can be specifically set according to a specific implementation scenario. For example, as the carbon dioxide concentration exceeds the standard, the controller pushes a message on the intelligent APP to remind the user that the carbon dioxide concentration exceeds the standard. The user clicks 'open immediately', and the new fan is started; clicking 'not to open', and no longer pushing carbon dioxide by the APP within 4h for detection; if the user has no operation all the time, the fresh air fan is automatically started after 15 min.
It should be noted that the scheme of the above preferred embodiment is only a specific implementation scheme provided by the present application, and other manners of controlling the operation of the fresh air fan based on the carbon dioxide concentration and the operation state of the fresh air fan all belong to the protection scope of the present application.

By applying the scheme, the indoor carbon dioxide concentration can be accurately detected, the controlled fresh air volume is closest to the ideal state of a user, and the user experience is improved.
