[0002] An air conditioning device consists of an indoor unit and an outdoor unit, which perform heat exchange through the indoor unit and the outdoor unit to achieve functions such as refrigeration and heating. When the indoor air contains a large amount of moisture and the evaporator absorbs a large amount of heat, it will cause water accumulation, frosting, or even icing in the indoor unit. However, when frosting or freezing occurs in the indoor unit, it will reduce the heat exchange capacity of the air conditioning device, thereby affecting the working performance of the air conditioning device.

[0061] To make the above objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0062] In the prior art, the anti-freezing solution needs to obtain the sampled temperatures and operating states of the indoor and outdoor units, and the operating logic is usually in the main control of the outdoor unit. When the communication protocols between the indoor and outdoor units do not match or the communication is interrupted, the outdoor unit cannot obtain the key data of the indoor unit, resulting in a reduction or failure of the anti-freezing performance.

[0063] One of the core concepts of the embodiments of the present invention is to build a backup data transmission path by adding a first low-power module and a second low-power module. Even when the communication protocols between the indoor and outdoor unit main controls do not match or are interrupted, the operating data of the outdoor unit can still be transmitted to the indoor unit. The indoor unit obtains the outdoor unit data and combines its own data for logical judgment. Even when the communication between the indoor and outdoor units is interrupted, the anti-freezing logic can still be independently executed to ensure the normal operation of the anti-freezing function.

[0064] Refer to Figure 1 , which shows a structural block diagram of an air conditioner provided by an embodiment of the present invention. The air conditioner includes an outdoor unit 11, a first low-power module 12 provided on the outdoor unit 11, an indoor unit 13, and a second low-power module 14 provided on the indoor unit 13;

[0065] When the indoor and outdoor units use zero-fire communication, there may be a communication interruption. If the communication protocols between the indoor and outdoor units do not match, for example, the indoor unit uses RS-485 (RS-485 (also known as EIA-485) is a common serial communication standard that uses differential signal transmission and has strong anti-interference ability and long-distance communication ability), and the outdoor unit uses zero-fire, it is determined to be in a communication interruption state. When the indoor and outdoor units are in a communication interruption state, the user end sets to trigger special anti-freezing protection, and the manufacturer controls the indoor unit at the user end to trigger the special anti-freezing system.

[0066] The anti-freezing function needs to obtain the sampled temperatures and operating states of the indoor and outdoor units to determine whether to turn on. Due to the communication interruption between the indoor and outdoor units, the anti-freezing logic in the main control of the outdoor unit fails. Therefore, a first low-power module and a second low-power module are additionally added between the indoor and outdoor units to receive and transmit the outdoor unit temperature and the compressor operating state, and send them to the indoor unit to determine whether to turn on the anti-freezing function.

[0067] The outdoor unit 11 is used to obtain the operating data of the outdoor unit and send it to the first low-power module 12;

[0068] The outdoor unit is the core power part of the air conditioner system, responsible for heat exchange and compressor operation, and cooperates with the indoor unit to complete the refrigeration / heating cycle, including the core component compressor for driving the refrigerant cycle.

[0069] The first low-power module communicates with the outdoor unit, uses a common communication protocol to communicate with the outdoor unit of the unit, so as to construct a data link for the outdoor unit with different models or inconsistent communication matching. It is used to receive the operation data of the outdoor unit of the unit, and send the operation data of the outdoor unit of the unit to the indoor unit through the second low-power module, completing the data communication between the indoor unit and the outdoor unit.

[0070] In the embodiment of the present invention, after the communication between the indoor unit and the outdoor unit is interrupted, the outdoor unit obtains the operation data of the outdoor unit of the unit, including the compressor operation time, the operation state data of the condenser, and the outdoor ambient temperature, etc. These data reflect the operation state of the outdoor unit of the air conditioner and provide a reference basis for turning on the anti-freezing function. The outdoor unit sends the obtained operation data of the outdoor unit to the first low-power module.

[0071] The first low-power module 12 is used to receive the operation data of the outdoor unit sent by the outdoor unit 11 and send it to the second low-power module 14;

[0072] The first low-power module communicates with the outdoor unit and the second low-power module. The first low-power module communicates with the outdoor unit using a common communication protocol, and the first low-power module communicates with the second low-power module using a wired or wireless connection.

[0073] In the embodiment of the present invention, the first low-power module receives the operation data of the outdoor unit sent by the outdoor unit and sends the operation data of the outdoor unit to the second low-power module.

[0074] The second low-power module 14 is used to receive the operation data of the outdoor unit sent by the first low-power module 12 and send it to the indoor unit 13;

[0075] The second low-power module communicates with the indoor unit and the first low-power module. The second low-power module communicates with the indoor unit using a common communication protocol, and the second low-power module communicates with the first low-power module using a wired or wireless connection.

[0076] In the embodiment of the present invention, the second low-power module receives the operation data of the outdoor unit sent by the first low-power module and sends the operation data of the outdoor unit to the indoor unit.

[0077] The indoor unit 13 is used to receive the operation data of the outdoor unit sent by the second low-power module 14, obtain the operation data of the indoor unit, and determine whether to turn on the anti-freezing function according to the operation data of the outdoor unit and the operation data of the indoor unit.

[0078] The indoor unit is one of the core components of the air-conditioning system, mainly responsible for air conditioning and circulation, and works in coordination with the outdoor unit to achieve the refrigeration / heating function. The second low-power module communicates with the indoor unit, uses a common communication protocol to communicate with the indoor unit of the unit, so as to construct a data link for the outdoor unit with different models or inconsistent communication matching.

[0079] The anti-freezing function (also known as anti-freeze protection or anti-frost function) is a protection mechanism for air conditioners, mainly used to prevent the evaporator of the air conditioner from freezing due to abnormal conditions during the heating or cooling mode, which may damage the equipment.

[0080] In the embodiment of the present invention, the indoor unit receives the outdoor unit operation data sent by the second low-power module, and obtains the indoor unit operation data including the evaporator operation temperature and the indoor ambient temperature, etc. These data reflect the operation state of the indoor unit of the air conditioner and provide a reference basis for turning on the anti-freezing function. After the indoor unit obtains the outdoor unit operation data and the indoor unit operation data, it determines whether to turn on the anti-freezing function according to the outdoor unit operation data and the indoor unit operation data.

[0081] Refer to Figure 2 , which shows the structural block diagram of a low-power module of an air conditioner provided by an embodiment of the present invention. The first low-power module and the second low-power module both include a transceiver module, a control module, and a communication module. The transceiver module is connected to the control module to communicate with each other, and the communication module is connected to the control module to communicate with each other.

[0082] The low-power communication module is composed of a transceiver module, a control module, and a communication module. The function of the transceiver module is to send and receive data with other low-power modules, and transmit data in a wired or wireless form. The control module plays the role of processing, relaying, and caching data, and is in a sleep state when there is no data to be processed. The function of the communication module is to communicate with the indoor unit and the outdoor unit. For example, taking the outdoor unit as an example, the communication module communicates with the outdoor unit through a general communication protocol to obtain the outdoor unit operation data, then sends the outdoor unit operation data to the control module, and then sends the outdoor unit operation data to the low-power module at the indoor unit end through the transceiver module.

[0083] The first low-power module 12 includes a first transceiver module 121, a first control module 122, and a first communication module 123; the first communication module 123 is used to receive the outdoor unit operation data sent by the outdoor unit 11; and send the outdoor unit operation data to the first control module 122;

[0084] In the embodiment of the present invention, the first communication module in the first low-power module communicates with the outdoor unit through a general communication protocol. After the outdoor unit obtains the outdoor unit operation data, it sends it to the first communication module. After the first communication module receives the outdoor unit operation data sent by the outdoor unit, it sends the outdoor unit operation data to the first control module.

[0085] The first control module 122 is used to be in a sleep state when the first preset condition is not met, or to switch from the sleep state to a working state when the first preset condition is met; in the working state, it receives the outdoor unit operation data sent by the first communication module 123 and sends the outdoor unit operation data to the first transceiver module 121;

[0086] Considering that the ambient temperature, the operating state of the compressor, and the compressor operation control instruction have non-real-time update characteristics, the control module in the low-power consumption module will be in a sleep state for a long time to reduce working losses. Only when data needs to be sent and received or updated, the control module will enter the working mode, which can reduce unnecessary working losses and energy consumption.

[0087] The first preset condition is the basis condition for the first control module to switch from the sleep state to the working state. Only when the first preset condition is met, the first control module will switch from the sleep state to the working state. When the first preset condition is not met, the first control module will switch to the sleep state.

[0088] In an embodiment of the present invention, the first control module is in a sleep state when the first preset condition is not met, or switches from the sleep state to the working state when the first preset condition is met. When the first control module is in the working state, it receives the outdoor unit operation data sent by the first communication module and caches the outdoor unit operation data, and then sends the outdoor unit operation data to the first transceiver module.

[0089] The first transceiver module 121 is used to receive the outdoor unit operation data sent by the first control module 122 and send the outdoor unit operation data to the second low-power consumption module 14.

[0090] In an embodiment of the present invention, the first transceiver module plays an important data transmission function in the whole system. After receiving the outdoor unit operation data sent by the first control module, which covers various key parameters of the outdoor unit operation, the first transceiver module will quickly and stably send the received outdoor unit operation data to the second low-power consumption module to ensure the smoothness and timeliness of data transmission.

[0091] The second low-power consumption module 14 includes a second transceiver module 141, a second control module 142, and a second communication module 143; the second transceiver module 141 is used to receive the outdoor unit operation data sent by the first transceiver module 121 and send the outdoor unit operation data to the second control module 142;

[0092] In an embodiment of the present invention, the second low-power module includes a second transceiver module, a second control module, and a second communication module. The second transceiver module is connected to the second control module to communicate with each other, and the second communication module is connected to the second control module to communicate with each other. The second transceiver module is connected to the first transceiver module wirelessly or wiredly, enabling communication between the first low-power module and the second low-power module. After receiving the external unit operation data sent by the first transceiver module, the second transceiver module sends the external unit operation data to the second control module.

[0093] The second control module 142 is configured to be in a sleep state when the second preset condition is not met, or to switch from the sleep state to a working state when the second preset condition is met; in the working state, it receives the external unit operation data sent by the second transceiver module 141 and sends the external unit operation data to the second communication module 143;

[0094] The second preset condition is the basis for the second control module to switch from the sleep state to the working state. Only when the second preset condition is met will the second control module switch from the sleep state to the working state, and when the second preset condition is not met, the second control module will switch to the sleep state.

[0095] In an embodiment of the present invention, the second control module is in a sleep state when the second preset condition is not met, or switches from the sleep state to the working state when the second preset condition is met. When the second control module is in the working state, it receives the external unit operation data sent by the second transceiver module and then sends the external unit operation data to the second communication module.

[0096] The second communication module 143 is configured to receive the external unit operation data sent by the second control module 142 and send the external unit operation data to the internal unit 13.

[0097] In an embodiment of the present invention, the second communication module in the second low-power module communicates with the internal unit through a general protocol. After receiving the external unit operation data sent by the second control module, the second communication module sends the external unit operation data to the internal unit. After receiving the external unit operation data, the internal unit determines whether to activate the anti-freezing function in combination with the internal unit operation data.

[0098] The first preset condition is that the external unit operation data is updated; or, when communication between the internal unit and the external unit is interrupted and the internal unit operation data is updated; the second preset condition is that the internal unit operation data is updated; or, when communication between the internal unit and the external unit is interrupted and the external unit operation data is updated.

[0099] In an embodiment of the present invention, the first preset condition is used to determine whether the first control module in the first low-power module needs to be woken up and switched from the sleep state to the working state. The first communication module communicates with the outdoor unit and receives the operation data of the outdoor unit. The first control module will cache the operation data of the outdoor unit. When the received operation data of the outdoor unit is inconsistent with the operation data of the outdoor unit cached by the first control module, it indicates that the operation data of the outdoor unit needs to be updated. Therefore, it is necessary to wake up the first control module to switch from the sleep state to the working state and re-cache the operation data of the outdoor unit.

[0100] Alternatively, when the communication between the indoor unit and the outdoor unit is interrupted, if the second communication module receives that the operation data of the indoor unit is inconsistent with the operation data of the indoor unit cached by the second control module, and determines that the operation data of the indoor unit needs to be updated, and judges that the indoor unit needs to send data to the outdoor unit, the second transceiver module will send a paging signal to the first transceiver module, and the first transceiver module will send this paging signal to the first control module to wake it up. The first control module will switch from the sleep state to the working state to receive data from the indoor unit. At the same time, if the indoor unit needs to send a control instruction to the outdoor unit, the second transceiver module will send a paging signal to the first transceiver module, and the first transceiver module will send this paging signal to the first control module to wake it up. After being woken up, the first control module will send the control instruction to the indoor unit through the first communication module.

[0101] The second preset condition is used to determine whether the second control module in the second low-power module needs to be woken up and switched from the sleep state to the working state. The second communication module communicates with the indoor unit and receives the operation data of the indoor unit. The second control module will cache the operation data of the indoor unit. When the received operation data of the indoor unit is inconsistent with the operation data of the indoor unit cached by the second control module, it indicates that the operation data of the indoor unit needs to be updated. Therefore, it is necessary to wake up the second control module to switch from the sleep state to the working state and re-cache the operation data of the indoor unit.

[0102] Alternatively, when the communication between the indoor unit and the outdoor unit is interrupted, if the first communication module receives that the operation data of the outdoor unit is inconsistent with the operation data of the outdoor unit cached by the first control module, and determines that the operation data of the outdoor unit needs to be updated, and judges that the outdoor unit needs to send data to the indoor unit, the first transceiver module will send a paging signal to the second transceiver module, and the second transceiver module will send this paging signal to the second control module to wake it up. The second control module will switch from the sleep state to the working state to receive data from the outdoor unit.

[0103] When the control module of the low-power module does not receive a paging signal within a period of time or the operation data of the indoor and outdoor units does not need to be updated, it will re-enter the sleep mode to reduce the power consumption caused by the addition of extra modules.

[0104] The outdoor unit 11 includes a compressor; the indoor unit 13 includes an evaporator; the operating data of the outdoor unit includes the operating time of the compressor and the outdoor ambient temperature; the operating data of the indoor unit includes the inner pipe temperature of the evaporator and the indoor ambient temperature;

[0105] The air conditioner compressor is the main component of the refrigeration system, responsible for compressing the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas, driving the entire refrigeration cycle. The operating time of the air conditioner compressor is a key factor affecting the performance, energy consumption, and service life of the air conditioner.

[0106] The air conditioner evaporator is a key heat exchange component in the refrigeration system. Its main function is to absorb indoor heat to achieve the refrigeration effect. The low-temperature and low-pressure liquid refrigerant evaporates and absorbs heat in the pipe, and the indoor air is forced by the fan to pass through the fin gaps, and the heat is transferred from the air to the refrigerant to achieve cooling. The inner pipe temperature of the evaporator is a key parameter for the operation of the air conditioner system, directly affecting the refrigeration efficiency and system safety.

[0107] The indoor unit 13 is configured to determine whether to activate the anti-freezing function according to the operating time of the compressor, the outdoor ambient temperature, the inner pipe temperature of the evaporator, and the indoor ambient temperature.

[0108] In the embodiment of the present invention, in the operating mechanism of the entire air conditioner system, the indoor unit combines multiple important parameters to determine whether to activate the anti-freezing function. Specifically, it determines whether to activate the anti-freezing function according to the operating time of the compressor, the outdoor ambient temperature, the inner pipe temperature of the evaporator, and the indoor ambient temperature. The operating time of the compressor may cause changes in the system operating conditions due to long-term operation; the low outdoor ambient temperature may increase the freezing risk; it also obtains the inner pipe temperature of the evaporator in real time, which directly reflects the state of the refrigeration link; and it always monitors the indoor ambient temperature to ensure indoor comfort. The indoor unit will comprehensively analyze and evaluate these data. Once it determines that there is a freezing hazard, it will activate the anti-freezing function in a timely manner, thereby ensuring the stable operation and high efficiency of the air conditioner system.

[0109] The indoor unit 13 is configured to determine to activate the anti-freezing function when the operating time of the compressor meets a first threshold duration and the inner pipe temperature of the evaporator is less than a first threshold temperature within a continuous preset time; and / or when the outdoor ambient temperature is less than or equal to a second threshold temperature, the continuous operating time of the compressor is greater than a second threshold duration, and after the inner pipe temperature of the evaporator drops to the lowest temperature value and then rises again, the difference between the inner pipe temperature of the evaporator and the lowest temperature value is greater than a preset temperature difference, determine to activate the anti-freezing function; and / or when the outdoor ambient temperature is less than or equal to a third threshold temperature, the indoor ambient temperature is greater than a fourth threshold temperature, and the continuous operating time of the compressor is greater than a third threshold duration, determine to activate the anti-freezing function; and / or when the outdoor ambient temperature is less than or equal to a third threshold temperature, the indoor ambient temperature is greater than a fourth threshold temperature, and the continuous operating time of the compressor is greater than a fourth threshold duration, determine to activate the anti-freezing function.

[0110] In an embodiment of the present invention, the indoor unit comprehensively analyzes four parameters including the operating time of the compressor, the outdoor ambient temperature, the inner pipe temperature of the evaporator, and the indoor ambient temperature to determine whether to activate the anti-freezing function. Based on the judgment of these four parameters, when the operating time of the compressor meets a first threshold duration and the inner pipe temperature of the evaporator is less than a first threshold temperature within a continuous preset time; and / or when the outdoor ambient temperature is less than or equal to a second threshold temperature, the continuous operating time of the compressor is greater than a second threshold duration, and after the inner pipe temperature of the evaporator drops to the lowest temperature value and then rises again, the difference between the inner pipe temperature of the evaporator and the lowest temperature value is greater than a preset temperature difference; and / or when the outdoor ambient temperature is less than or equal to a third threshold temperature, the indoor ambient temperature is greater than a fourth threshold temperature, and the continuous operating time of the compressor is greater than a third threshold duration; and / or when the outdoor ambient temperature is less than or equal to a third threshold temperature, the indoor ambient temperature is greater than a fourth threshold temperature, and the continuous operating time of the compressor is greater than a fourth threshold duration. When the indoor unit determines that at least one of the above conditions is met, it will activate the anti-freezing function.

[0111] After the anti-freezing function is activated, if the inner pipe temperature of the evaporator is greater than a fifth threshold temperature within a continuous second preset time, or the difference between the inner pipe temperature of the evaporator and the indoor ambient temperature is greater than or equal to a preset temperature difference within a continuous third preset time, the indoor unit will deactivate the anti-freezing function.

[0112] The indoor unit 13 is configured to send a stop instruction to the second low-power module 14 and stop operating after determining to activate the anti-freezing function;

[0113] The second low-power module 14 is configured to receive the stop instruction sent by the indoor unit 13 and send it to the first low-power module 12;

[0114] The first low-power module 12 is configured to receive the stop instruction sent by the second low-power module 14 and send it to the outdoor unit 11;

[0115] The outdoor unit 11 is configured to receive the stop instruction sent by the first low-power module 12 and stop running after receiving the stop instruction.

[0116] In the embodiment of the present invention, after the indoor unit determines to activate the anti-freezing function, it will send a stop instruction to the second low-power module and stop running. The second low-power module receives the stop instruction sent by the indoor unit and sends the stop instruction to the first low-power module. The first low-power module receives the stop instruction sent by the second low-power module, sends it to the outdoor unit after receiving the stop instruction, and the outdoor unit receives the stop instruction sent by the first low-power module and stops running after receiving the stop instruction. This realizes the stop of the compressor of the outdoor unit and prevents the evaporator of the indoor unit from frosting and icing.

[0117] Referring to Figure 3 , a logic flowchart of the anti-freezing function of an air conditioner provided by an embodiment of the present invention is shown;

[0118] In this embodiment, first, the communication status between the indoor unit and the outdoor unit needs to be obtained to determine whether the indoor unit and the outdoor unit are communicating normally. If the communication between the indoor unit and the outdoor unit is interrupted, it will enter the special anti-freezing mode, and the communication between the indoor unit and the outdoor unit is completed through the first low-power module and the second low-power module. Entering the special anti-freezing mode requires waking up the control module in the low-power module to send and receive data. The indoor unit receives the operation data of the outdoor unit through the first low-power module and the second low-power module, and obtains the operation data of the indoor unit to determine whether to activate the anti-freezing function. After the indoor unit activates the anti-freezing function, it sends a control instruction to the outdoor unit. At the same time, the indoor unit also needs to determine whether to deactivate the anti-freezing function, and deactivate the anti-freezing function when the anti-freezing conditions are not met.

By adding a first low-power consumption module and a second low-power consumption module to construct a backup data transmission path, even when the main control communication protocols of the indoor and outdoor units do not match or are interrupted, the outdoor unit operation data can still be transmitted to the indoor unit, and the indoor unit can obtain the outdoor unit data and perform logical judgment in combination with its own data. Even when the communication between the indoor and outdoor units is interrupted, the anti-freezing logic can still be independently executed to ensure the normal operation of the anti-freezing function.
