Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and in particular to an air conditioning device and its control method, apparatus, equipment and air conditioning system. Background Technology

[0002] Air conditioning equipment refers to devices that supply treated air to a designated space to maintain specified temperature, humidity, etc. Non-communication air conditioning equipment is a type of air conditioning equipment. The indoor and outdoor units of non-communication air conditioning equipment do not communicate with each other; they operate independently without interference. Therefore, when replacing the equipment, only the outdoor unit needs to be replaced, while the indoor unit remains unchanged. Different brands of indoor and outdoor units can be used interchangeably, making installation simple and cost-effective.

[0003] However, traditional air conditioning units without communication capabilities often have a constant heating and cooling capacity, and the unit can only control the indoor temperature by frequently stopping at specific temperature points. In this case, the unit's energy efficiency and comfort are often poor, and the frequent start-stop of the fan inside the compressor results in high noise levels, which also affects the reliability of the unit's operation. Summary of the Invention

[0004] Therefore, it is necessary to provide an air conditioning device, control method, apparatus, equipment, and air conditioning system that can improve the operational reliability of the unit, addressing the issue of low operational reliability of traditional air conditioning equipment without communication at temperatures.

[0006] The thermostat has an active power signal interface. The indoor unit or the outdoor unit that has no communication connection with the thermostat has two or more passive power signal interfaces. Each passive power signal interface has no communication connection with the active power signal interface. When different passive power signal interfaces receive power signals, the working state of the indoor unit or the outdoor unit is different.

[0007] In one embodiment, the indoor unit has no communication connection with the thermostat, while the outdoor unit has a communication connection with the thermostat; or, the indoor unit has a communication connection with the thermostat, while the outdoor unit has no communication connection with the thermostat.

[0012] Based on the indoor ambient temperature and the temperature set by the thermostat, a power signal is sent to the corresponding passive power signal interface.

[0013] In one embodiment, sending a power signal to the corresponding passive power signal interface based on the indoor ambient temperature and the temperature set by the thermostat includes:

[0014] Based on the indoor ambient temperature and the temperature set by the thermostat, a power signal is sent to a different number of passive power signal interfaces in a device.

[0015] In one embodiment, sending power signals to different numbers of passive power signal interfaces based on the indoor ambient temperature and the temperature set by the thermostat includes:

[0016] If the indoor ambient temperature is greater than the upper limit of the temperature fluctuation set by the thermostat when cooling, or less than the lower limit of the temperature fluctuation set by the thermostat when heating, a power signal is sent to a first number of passive power signal interfaces in a device.

[0017] If the indoor ambient temperature is greater than the temperature set by the thermostat during cooling and less than the upper limit of the fluctuation of the temperature set by the thermostat, or if the indoor ambient temperature is greater than the lower limit of the fluctuation of the temperature set by the thermostat during heating and less than the temperature set by the thermostat, a power signal is sent to the second number of passive power signal interfaces in a device.

[0018] If the indoor ambient temperature is lower than the set temperature of the thermostat when cooling, or higher than the set temperature of the thermostat when heating, a power signal is sent to a third number of passive power signal interfaces in a device; the first number is greater than the second number, and the second number is greater than the third number.

[0019] In one embodiment, the air conditioning equipment control method further includes:

[0020] The operating frequency of the communication-connected device is adjusted according to the indoor ambient temperature and the temperature set by the thermostat.

[0021] In one embodiment, adjusting the operating frequency of a device without a communication connection based on the indoor ambient temperature and the temperature set by the thermostat includes:

[0022] Based on the difference between the indoor ambient temperature and the temperature set by the thermostat, adjust the operating frequency of the communication-connected device; and / or,

[0023] The rate of change of the operating frequency of the communication-connected devices is adjusted according to the rate of change of the indoor ambient temperature.

[0024] In one embodiment, the air conditioning equipment control method further includes: if the air conditioning equipment stops operating, stopping the transmission of power signals to the passive power signal interface.

[0025] Thirdly, this application also provides an air conditioning equipment control device, implemented based on the aforementioned air conditioning equipment, comprising:

The indoor or outdoor unit without a communication connection to the thermostat has two or more passive power signal interfaces. Each passive power signal interface has no communication connection with the active power signal interface. When different passive power signal interfaces receive power signals, the operating state of the corresponding indoor or outdoor unit differs. Because at least one of the indoor or outdoor units has no communication connection with the thermostat, when only the outdoor unit is replaced, the replaced outdoor unit can still work with the original indoor unit. The active power signal interface of the thermostat is connected to the passive power signal interface without a communication device. By sending power signals to different passive power signal interfaces, the operating state of the indoor unit or the outdoor unit where the passive power signal interface is located can be adjusted.

[0044] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0046] It is understood that the terms "first," "second," etc., used herein may be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this application, a first resistor may be referred to as a second resistor, and similarly, a second resistor may be referred to as a first resistor. Both the first resistor and the second resistor are resistors, but they are not the same resistor.

[0047] It is understood that the term "connection" in the following embodiments should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have electrical signal or data transmission with each other.

[0048] It is understandable that "at least one" refers to one or more, and "multiple" refers to two or more. "At least a part of an element" refers to part or all of an element.

[0049] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0050] This application provides an air conditioning device, also referred to as a unit. The unit includes a thermostat, an indoor unit, and an outdoor unit. The thermostat is used to obtain a set temperature based on user-sent instructions; this set temperature can be understood as the target temperature. The thermostat may be equipped with a temperature detection device, which can be a temperature sensor, used to detect the ambient temperature of the environment in which the thermostat is located. For example, the thermostat is typically installed indoors, and the temperature detection device on the thermostat is used to detect the indoor ambient temperature. The outdoor unit is usually installed outdoors, and the indoor unit is usually installed indoors. For example, as shown... Figure 1 As shown, the outdoor unit includes a variable frequency compressor 01, a four-way valve 02, a condenser 03, an electronic expansion valve 04, a speed-regulating temperature sensor 07 in the external pipe, a pressure sensor 08, and an exhaust temperature sensor 09. The condenser 03 and the fan are located in the same air duct. The indoor unit includes a thermal expansion valve 05 and an evaporator 06. The blower and the evaporator 06 are located in the same air duct.

[0051] In temperature control equipment, at least one of the indoor and outdoor units has no communication connection with the thermostat. Specifically, no communication connection means that there is no communication protocol between the connected units, and neither is aware of the other's operating status. For example, when the indoor and outdoor units have no communication connection, there is no communication protocol between them; the outdoor unit is unaware of the indoor unit's operating status, and vice versa. "At least one of the indoor and outdoor units has no communication connection with the thermostat" means that either the indoor or outdoor unit has no communication connection with the thermostat, or both the indoor and outdoor units may have no communication connection.

[0052] The thermostat has an active power signal interface used to transmit power signals. Indoor or outdoor units that are not connected to the thermostat have two or more passive power signal interfaces, none of which are connected to the active power signal interface. In other words, if the indoor unit is not connected to the thermostat, it has two or more passive power signal interfaces, and these interfaces are not connected to the thermostat's active power signal interface; similarly, if the outdoor unit is not connected to the thermostat, it has two or more passive power signal interfaces, and these interfaces are not connected to the thermostat's active power signal interface.

[0053] The number of passive power signal interfaces can be configured according to actual needs, for example, there can be two or three. The number of active power signal interfaces can be one or more. Furthermore, the number of active power signal interfaces can be equal to the number of passive power signal interfaces. Thus, each active power signal interface can be connected to one passive power signal interface, allowing power signals to be transmitted independently through different channels, resulting in more accurate control of the air conditioning equipment.

[0054] Different passive power signal interfaces result in different operating states for the indoor or outdoor unit. For example, different passive power signal interfaces in the indoor unit will result in different operating states, and the same applies to the outdoor unit. Taking an indoor unit with two passive power signal interfaces (a first passive power signal interface and a second passive power signal interface) as an example, if the first passive power signal interface receives a power signal, the indoor unit will operate at a high setting; if the second passive power signal interface receives a power signal, the indoor unit will operate at a low setting. Therefore, by sending power signals to different passive power signal interfaces, the devices connected to those interfaces can be controlled to operate in different states, thus adjusting the unit's output capacity and better meeting user needs.

[0055] The aforementioned air conditioning equipment includes a thermostat, an indoor unit, and an outdoor unit. At least one of the indoor and outdoor units has no communication connection with the thermostat. The thermostat has an active power signal interface. The indoor or outdoor unit without a communication connection to the thermostat has two or more passive power signal interfaces. Each passive power signal interface has no communication connection with the active power signal interface. When different passive power signal interfaces receive power signals, the operating state of the corresponding indoor or outdoor unit differs. Because at least one of the indoor or outdoor units has no communication connection with the thermostat, when only the outdoor unit is replaced, the replaced outdoor unit can still work with the original indoor unit. The active power signal interface of the thermostat connects to the passive power signal interface without a communication device. By sending power signals to different passive power signal interfaces, the operating state of the indoor unit or the outdoor unit connected to the passive power signal interface can be adjusted. This allows for on-demand adjustment of the air conditioning equipment's operating state, reducing noise and energy loss caused by frequent start-ups and shutdowns, and improving the unit's operational reliability.

[0056] In one embodiment, the indoor unit has no communication connection with the thermostat, while the outdoor unit has a communication connection with the thermostat. Alternatively, the indoor unit has a communication connection with the thermostat, while the outdoor unit does not.

[0057] Specifically, the indoor unit has no communication connection with the thermostat, while the outdoor unit does. The power signal can be a 24V power signal or other values; as long as the passive power signal interface has both on and off states, the judgment function can be achieved. The number of passive power signal interfaces in the indoor unit is not unique; for example, it can have three. The number of active power signal interfaces in the thermostat is also not unique; for example, it can be the same as the number of passive power signal interfaces in the indoor unit, or it can have three.

[0058] For example, such as Figure 2 As shown, the indoor unit and thermostat are connected via a 24V non-communication connection. The indoor unit has three 24V power signal interfaces: High (G3), Medium (G2), and Low (G1), which are connected to the thermostat's active power signal interfaces G3, G2, and G1, respectively. The outdoor unit and thermostat are connected via RS485 or other data transmission methods with communication capabilities. The outdoor unit includes communication terminals H1 and H2, which are connected to the thermostat's communication terminals H1 and H2, respectively. In addition, the indoor unit may include other power signal interfaces, such as a four-way valve signal terminal B, an electric heating signal terminal W1, and a 24V power supply terminal. The indoor unit can determine the switching state of the four-way valve by whether terminal B receives 24V voltage. It can be preset that when terminal B receives 24V voltage, the outdoor unit's four-way valve switches to heat pump mode, and when terminal B does not receive 24V voltage, the outdoor unit's four-way valve switches to cooling mode only. Alternatively, it can be preset that terminal B is energized during cooling and de-energized during heating.

[0059] Similarly, the indoor unit communicates with the thermostat, while the outdoor unit does not. The power signal can be a 24V signal or other values; the detection function can be achieved as long as the passive power signal interface exhibits both on and off states. The number of passive power signal interfaces in the outdoor unit is not unique; for example, it can have three. The number of active power signal interfaces in the thermostat is also not unique; for example, it can be the same as the number of passive power signal interfaces in the outdoor unit, or it can have three.

[0060] For example, such as Figure 2 As shown, the outdoor unit and the thermostat are connected via a 24V non-communication connection. The outdoor unit has three 24V power signal interfaces: High (Y3), Medium (Y2), and Low (Y1). The indoor unit and the thermostat are connected via RS485 or other data transmission-enabled communication methods. The indoor unit includes communication terminals. Additionally, the outdoor unit may include other power signal interfaces.

[0061] In this embodiment, one of the indoor and outdoor units has no communication connection with the thermostat. When it is necessary to replace the outdoor or indoor unit, the newly installed components can be matched with the original components, making it widely applicable.

[0062] In one embodiment, the indoor unit has no communication connection with the thermostat, and the outdoor unit has no communication connection with the thermostat.

[0063] Specifically, when the indoor unit and thermostat are not connected, the thermostat's active power signal interface connects to the indoor unit's passive power signal interface. The thermostat can send power signals to the indoor unit's passive power signal interface through its active power signal interface. When different passive power signal interfaces of the indoor unit receive power signals, the indoor unit is in different operating states. Similarly, when the outdoor unit and thermostat are not connected, the thermostat's active power signal interface connects to the outdoor unit's passive power signal interface. The thermostat can send power signals to the outdoor unit's passive power signal interface through its active power signal interface. When different passive power signal interfaces of the outdoor unit receive power signals, the outdoor unit is in different operating states.

[0064] For example, such as Figure 3 As shown, the indoor unit and the thermostat are connected via a 24V non-communication connection, as are the outdoor unit and the thermostat. The indoor unit has three 24V power signal interfaces: High (G3), Medium (G2), and Low (G1), which are connected to the thermostat's active power signal interfaces G3, G2, and G1, respectively. The outdoor unit has three 24V power signal interfaces: High (Y3), Medium (Y2), and Low (Y1), which are connected to the thermostat's active power signal interfaces Y3, Y2, and Y1, respectively.

[0065] In this embodiment, the indoor unit and the thermostat have no communication connection, and the outdoor unit and the thermostat also have no communication connection. The outdoor unit can be paired with different indoor units, and can also meet the needs of users who only need to replace the outdoor unit when upgrading their devices.

[0066] In one embodiment, the indoor unit has two or more passive power signal interfaces, and the outdoor unit has two or more passive power signal interfaces. The passive power signal interfaces of the indoor unit and the passive power signal interfaces of the outdoor unit have no communication connection.

[0067] Besides the option where at least one of the indoor or outdoor units has no communication connection with the thermostat, the outdoor and indoor units can also be connected without communication. In this communication method, the indoor unit has two or more passive power signal interfaces, and the outdoor unit has two or more passive power signal interfaces, with no communication connection between the indoor and outdoor units' passive power signal interfaces. Furthermore, the number of passive power signal interfaces in the outdoor unit can be equal to the number in the indoor unit, allowing for one-to-one connection between the outdoor and indoor units' passive power signal interfaces. The outdoor unit can send power signals to the indoor unit's passive power signal interfaces to control the indoor unit's operating status. Alternatively, the indoor unit can also send power signals to the outdoor unit's passive power signal interfaces to control the outdoor unit's operating status.

[0068] In this embodiment, the indoor unit has two or more passive power signal interfaces, and the outdoor unit has two or more passive power signal interfaces. The passive power signal interfaces of the indoor unit and the outdoor unit are not communicatively connected. Therefore, the outdoor unit can send power signals to the passive power signal interfaces of the indoor unit to control the operating status of the indoor unit. The indoor unit can also send power signals to the passive power signal interfaces of the outdoor unit to control the operating status of the outdoor unit.

[0069] In one embodiment, an air conditioning equipment control method is provided, implemented based on an air conditioning equipment according to any of the above embodiments. The air conditioning equipment control method can be executed by a controller, which can be a controller within a thermostat, a controller within an outdoor unit, or a controller within an indoor unit, determined by the connection method of the air conditioning equipment. For example, if the indoor unit has no communication connection with the thermostat, but the outdoor unit has a communication connection with the thermostat, the air conditioning equipment control method can be executed by the controller within the thermostat or by the controller within the outdoor unit. If the indoor unit has a communication connection with the thermostat, but the outdoor unit does not, the air conditioning equipment control method can be executed by the controller within the thermostat or by the controller within the indoor unit. If neither the indoor nor outdoor unit has a communication connection with the thermostat, the air conditioning equipment control method can be executed by the controller within the thermostat. Figure 4 As shown, the air conditioning equipment control method includes the following steps:

[0070] Step 402: Obtain the indoor ambient temperature and the thermostat set temperature.

[0071] The indoor ambient temperature refers to the temperature within the space where the indoor unit operates. This temperature is detected by a temperature detection device and sent to the controller. The temperature detection device can be located on the thermostat and is typically a built-in temperature sensor. The thermostat setpoint is the user-defined temperature. Users can set the temperature via the thermostat, and the thermostat receives the setpoint based on the user's command. This setpoint can be understood as the user's desired target temperature. Furthermore, the controller can also receive operating mode commands from the thermostat, which are used to control whether the air conditioning unit operates in heating or cooling mode.

[0072] Step 404: Send a power signal to the corresponding passive power signal interface according to the indoor ambient temperature and the temperature set by the thermostat.

[0073] After obtaining the indoor ambient temperature and the thermostat set temperature, the controller can determine the user's heating or cooling needs. Based on the magnitude of these needs, it sends a corresponding passive power signal to the corresponding device, causing the device connected to that passive power signal to operate in the user's desired state.

[0074] For example, the controller can send a power signal to the corresponding passive power signal interface based on the difference between the indoor ambient temperature and the thermostat's set temperature. If the difference between the indoor ambient temperature and the thermostat's set temperature is large, considering the user's heating or cooling demand, a power signal can be sent to the passive power signal interface of the controller for high-power operation, controlling the device at the passive power signal interface to operate in a high-power state, thereby increasing the unit's output capacity. Alternatively, if the difference between the indoor ambient temperature and the thermostat's set temperature is small, considering the user's heating or cooling demand, a power signal can be sent to the passive power signal interface of the controller for low-power operation, controlling the device at the passive power signal interface to operate in a low-power state, thereby saving unit energy consumption.

[0075] In the above-mentioned air conditioning equipment control method, after obtaining the indoor ambient temperature and the thermostat set temperature, a power signal is sent to the corresponding passive power signal interface according to the indoor ambient temperature and the thermostat set temperature. The unit output capacity of the air conditioning equipment can be adjusted according to the indoor ambient temperature and user needs, making the operation of the air conditioning equipment more reliable.

[0076] In one embodiment, such as Figure 5 As shown, step 404 includes step 502.

[0077] Step 502: Based on the indoor ambient temperature and the temperature set by the thermostat, send power signals to different numbers of passive power signal interfaces in a device.

[0078] When different numbers of passive power signal interfaces receive power signals, the operating state of the device at each passive power signal interface varies, for example, its operating power and output capability differ. After obtaining the indoor ambient temperature and the thermostat set temperature, power signals are sent to different numbers of passive power signal interfaces in a single device according to the different indoor ambient temperature and thermostat set temperature, thereby controlling the device at each passive power signal interface to operate in different states.

[0079] For example, if the thermostat has no communication connection with the indoor unit, and the indoor unit includes three passive power signal interfaces, the thermostat sends a power signal to one, two, or three passive power signal interfaces of the indoor unit based on the indoor ambient temperature and the thermostat's set temperature, thus enabling the indoor unit to operate at different settings. Similarly, if the thermostat has no communication connection with the outdoor unit, and the outdoor unit includes three passive power signal interfaces, the thermostat sends a power signal to one, two, or three passive power signal interfaces of the outdoor unit based on the indoor ambient temperature and the thermostat's set temperature, thus enabling the outdoor unit to operate at different settings.

[0080] In this embodiment, based on the indoor ambient temperature and the temperature set by the thermostat, a power signal is sent to a different number of passive power signal interfaces in a device. By controlling the number of passive power signal interfaces that receive the power signal, the indoor or outdoor unit can be controlled, and the working status of the indoor or outdoor unit can be adjusted even without communication.

[0081] In one embodiment, such as Figure 6 As shown, step 502 includes steps 602, 604 and 606.

[0082] Step 602: If the indoor ambient temperature is greater than the upper limit of the temperature fluctuation set by the thermostat when cooling, or less than the lower limit of the temperature fluctuation set by the thermostat when heating, send a power signal to the first number of passive power signal interfaces in a device.

[0083] The upper limit of the temperature fluctuation limit for the thermostat is the sum of the thermostat set temperature and the preset temperature difference, while the lower limit is the difference between the thermostat set temperature and the preset temperature difference. For example, if the preset temperature difference is 3℃, then the upper limit of the temperature fluctuation limit for the thermostat set temperature is the thermostat set temperature + 3℃, and the lower limit is the thermostat set temperature - 3℃.

[0084] The first number is greater than the second number, and the second number is greater than the third number. When the passive power signal interface of the first number receives a power signal, the operating power of the device is relatively high. When the passive power signal interface of the second number receives a power signal, the operating power of the device is moderate. When the passive power signal interface of the third number receives a power signal, the operating power of the device is relatively low.

[0085] If the indoor ambient temperature is greater than the upper limit of the temperature fluctuation set by the thermostat during cooling, and the cooling demand is relatively large, or if the indoor ambient temperature is less than the lower limit of the temperature fluctuation set by the thermostat during heating, and the heating demand is relatively large, in both cases, the controller sends a power signal to a first number of passive power signal interfaces in a device. For example, it sends a power signal to the first number of passive power signal interfaces of the indoor unit, so that the indoor unit operates at a high speed; or it sends a power signal to the first number of passive power signal interfaces of the outdoor unit, so that the outdoor unit operates at a high speed.

[0086] Step 604: If the indoor ambient temperature is greater than the temperature set by the thermostat during cooling and less than the upper limit of the fluctuation of the temperature set by the thermostat, or if the indoor ambient temperature is greater than the lower limit of the fluctuation of the temperature set by the thermostat during heating and less than the temperature set by the thermostat, send a power signal to the second number of passive power signal interfaces in one of the devices.

[0087] If the indoor ambient temperature is higher than the thermostat's set temperature but lower than the upper limit of the thermostat's set temperature fluctuation range during cooling, the unit's cooling demand is considered moderate. If the indoor ambient temperature is higher than the lower limit of the thermostat's set temperature fluctuation range but lower than the thermostat's set temperature during heating, the unit's heating demand is considered moderate. In both cases, the controller sends a power signal to a second number of passive power signal interfaces in one of the devices, for example, sending a power signal to a second number of passive power signal interfaces on the indoor unit to operate the indoor unit at a medium speed; or sending a power signal to a second number of passive power signal interfaces on the outdoor unit to operate the outdoor unit at a medium speed.

[0088] Step 606: If the indoor ambient temperature is lower than the thermostat set temperature during cooling, or higher than the thermostat set temperature during heating, send a power signal to the third passive power signal interface in one of the devices.

[0089] If the indoor ambient temperature is lower than the thermostat's set temperature during cooling, the unit's cooling demand is considered relatively low. If the indoor ambient temperature is higher than the thermostat's set temperature during heating, the unit's heating demand is considered relatively low. In both cases, the controller sends a power signal to a third passive power signal interface of a device, for example, sending a power signal to the third passive power signal interface of the indoor unit to make the indoor unit operate at a low speed; or sending a power signal to the third passive power signal interface of the outdoor unit to make the outdoor unit operate at a low speed.

[0090] In this embodiment, when the air conditioning device is in cooling mode or heating mode, based on the relationship between the indoor ambient temperature and the thermostat set temperature, the upper limit of the fluctuation of the thermostat set temperature, and the lower limit of the fluctuation of the thermostat set temperature, a power signal is sent to a first number of passive power signal interfaces in a device, or a second number of passive power signal interfaces in a device, or a third number of passive power signal interfaces in a device, so that the device where the passive power signal interface is located can operate in different states according to the required temperature difference.

[0091] In one embodiment, such as Figure 7 As shown, the air conditioning equipment control method also includes step 702.

[0092] Step 702: Adjust the operating frequency of the devices with communication connection according to the indoor ambient temperature and the temperature set by the thermostat.

[0093] If the actuator and the controlled device are connected via a communication link, the actuator can send control signals to the controlled device, specifically to the communication terminal of the passive device, thereby controlling the operating state of the controlled device. In this application, when the actuator is a thermostat, the controlled device can be an indoor unit or an outdoor unit that has a communication link with the thermostat.

[0094] If the indoor unit and thermostat are not connected, but the outdoor unit and thermostat are, the thermostat can send a power signal to the passive power signal interface of the indoor unit based on the indoor ambient temperature and the thermostat's set temperature, and adjust the outdoor unit's operating frequency accordingly.

[0095] In this embodiment, the operating frequency of the communication-connected devices is adjusted according to the indoor ambient temperature and the temperature set by the thermostat, so that the operating frequency of the communication-connected devices meets the cooling or heating requirements of the unit, thereby improving the operational reliability of the unit.

[0096] In one embodiment, such as Figure 8 As shown, step 702 includes step 802 and / or step 804.

[0097] Step 802: Adjust the operating frequency of the communication-connected device based on the difference between the indoor ambient temperature and the temperature set by the thermostat.

[0098] Specifically, if the difference between the indoor ambient temperature and the thermostat set temperature is large, and the unit's heating or cooling demand is high, the operating frequency of the communication-connected devices can be increased to improve the unit's output capacity. If the difference between the indoor ambient temperature and the thermostat set temperature is small, and the unit's heating or cooling demand is low, the operating frequency of the communication-connected devices can be decreased to save energy.

[0099] Furthermore, when the air conditioning unit is in cooling or heating mode, the operating frequency of the communication-connected device can be adjusted based on the relationship between the indoor ambient temperature and the thermostat's set temperature, the upper limit of the thermostat's set temperature fluctuation, and the lower limit of the thermostat's set temperature fluctuation. For example, if the indoor ambient temperature is greater than the upper limit of the thermostat's set temperature fluctuation during cooling, or less than the lower limit of the thermostat's set temperature fluctuation during heating, the operating frequency of the communication-connected device is adjusted to the highest frequency. If the indoor ambient temperature is greater than the thermostat's set temperature but less than the upper limit of the thermostat's set temperature fluctuation during cooling, or greater than the lower limit of the thermostat's set temperature fluctuation but less than the thermostat's set temperature during heating, the operating frequency of the communication-connected device is adjusted to gradually decrease as the absolute value of the difference between the indoor ambient temperature and the thermostat's set temperature decreases, and gradually increase as the absolute value of the difference between the indoor ambient temperature and the thermostat's set temperature increases. If the indoor ambient temperature is lower than the thermostat's set temperature when cooling, or higher than the thermostat's set temperature when heating, adjust the operating frequency of the communication-connected device to the lowest frequency.

[0100] Step 804: Adjust the rate of change of the operating frequency of devices without communication connection according to the rate of change of indoor ambient temperature.

[0101] Furthermore, when adjusting the operating frequency of devices without communication connections, the rate at which the frequency is increased or decreased can be determined based on the rate of change of the indoor ambient temperature. The faster the rate of change of the indoor ambient temperature, the faster the rate of change of the operating frequency of devices without communication connections; conversely, the slower the rate of change of the indoor ambient temperature, the slower the rate of change of the operating frequency of devices without communication connections.

[0102] In this embodiment, the operating frequency of the device with communication connection can be adjusted according to the difference between the indoor ambient temperature and the temperature set by the thermostat. The operating frequency of the device without communication connection can also be adjusted according to the rate of change of the indoor ambient temperature, so that the adjusted operating frequency of the device with communication connection is more in line with the actual operating conditions and user needs.

[0103] In one embodiment, such as Figure 9 As shown, the air conditioning equipment control method also includes step 902.

[0104] Step 902: If the air conditioning equipment stops operating, stop sending power signals to the passive power signal interface.

[0105] Specifically, the system can control whether or not to stop operation based on whether a stop command is received. If a stop command is received from the user, and considering that the air conditioning equipment needs to stop working, the system will control the air conditioning equipment to stop operating, stop sending power signals to the passive power signal interface, and cease adjusting the operating status of the indoor and outdoor units.

[0106] In this embodiment, if the air conditioning equipment stops operating, the power signal to the passive power signal interface is stopped, thus saving control steps.

[0107] To better understand the above embodiments, specific embodiments are listed below for detailed explanation.

[0108] In one embodiment, the air conditioning device includes a thermostat, an indoor unit, and an outdoor unit. The thermostat is used to obtain a set temperature based on user-sent instructions; this set temperature can be understood as the target temperature. The thermostat may be equipped with a temperature detection device, which can be a temperature sensor, used to detect the ambient temperature of the environment in which the thermostat is located. For example, the thermostat is typically installed indoors, and the temperature detection device on the thermostat is used to detect the indoor ambient temperature. The outdoor unit is typically installed outdoors, and the indoor unit is typically installed indoors. For example, as shown... Figure 1 As shown, the outdoor unit includes a variable frequency compressor 01, a four-way valve 02, a condenser 03, an electronic expansion valve 04, a speed-regulating temperature sensor 07 in the external pipe, a pressure sensor 08, and an exhaust temperature sensor 09. The condenser 03 and the fan are located in the same air duct. The indoor unit includes a thermal expansion valve 05 and an evaporator 06. The blower and the evaporator 06 are located in the same air duct.

[0109] In the first scenario, the indoor unit and thermostat are connected via a 24V non-communication connection. The indoor unit has three 24V power signal interfaces: High (G3), Medium (G2), and Low (G1), which connect to the thermostat's active power signal interfaces G3, G2, and G1, respectively. The outdoor unit and thermostat are connected via RS485 or other data-transferable communication methods. The outdoor unit includes communication terminals H1 and H2, which connect to the thermostat's communication terminals H1 and H2, respectively. Additionally, the indoor unit may include other power signal interfaces, such as a four-way valve signal terminal B, an electric heating signal terminal W1, and a 24V power supply terminal. The indoor unit can determine the four-way valve's switching state by whether terminal B receives 24V voltage. It can be preset that when terminal B receives 24V voltage, the outdoor unit's four-way valve switches to heat pump mode, and when terminal B does not receive 24V voltage, the outdoor unit's four-way valve switches to cooling mode only. Alternatively, it can be preset that terminal B is energized during cooling and de-energized during heating. R / B / W1 is for illustrative purposes only and may not be present.

[0110] like Figure 10As shown, after the unit starts running, the thermostat transmits the set temperature and indoor ambient temperature information to the outdoor unit. If the indoor ambient temperature is greater than the thermostat set temperature + t℃ during cooling, and less than the thermostat set temperature - t℃ during heating, the unit outputs its maximum capacity. The outdoor unit operates at the highest frequency corresponding to the outdoor environment, and the thermostat sends a 24V power signal for high-speed operation to the indoor unit (the medium and low fan speeds also output a 24V power signal at the same time). The indoor unit then operates at high fan speed. If, during cooling, the thermostat set temperature is less than the indoor ambient temperature and less than the thermostat set temperature + t℃, and during heating, the indoor ambient temperature is less than the thermostat set temperature, the outdoor unit frequency will gradually decrease as the absolute value of the difference between the indoor ambient temperature and the thermostat set temperature decreases. Conversely, the compressor frequency will gradually increase (the compressor frequency adjustment range is between the highest and lowest frequencies corresponding to the outdoor ambient temperature; the rate at which the compressor increases or decreases the frequency depends on the rate of change of the indoor ambient temperature; the faster the rate of change of the indoor ambient temperature, the faster the rate at which the compressor increases or decreases the frequency). The thermostat sends a 24V power signal for medium-speed operation to the indoor unit (a 24V power signal is also output at low fan speed, but not at high fan speed), and the indoor unit operates at medium fan speed. If the indoor ambient temperature is less than the thermostat's set temperature during cooling, and greater than the set temperature during heating, the outdoor unit operates at the lowest frequency corresponding to the outdoor ambient temperature. The thermostat sends a 24V power signal to the indoor unit for low-speed operation (no 24V power signal is output for medium and high speeds), and the indoor unit operates at a low fan speed. Alternatively, the outdoor unit can directly send a 24V power signal to the indoor unit, with both units using 24V control to regulate the indoor unit's fan speed, eliminating the need for the thermostat to send a 24V power signal. When the unit stops running, the thermostat will no longer send G3 / G2 / G1 fan speed signals. 't' is the preset temperature difference value, which can be set to 3℃ by default and then changed according to user needs. If using an indoor unit from another brand, which only has a single 24V power signal interface for fan speed, connect it only to the thermostat's low-speed interface, and so on.

[0111] In the second scenario, the outdoor unit and the thermostat are connected via a 24V non-communication connection. The outdoor unit has three 24V power signal interfaces: High (Y3), Medium (Y2), and Low (Y1). The indoor unit and the thermostat are connected via RS485 or other data transmission-enabled communication connection, and the indoor unit includes communication terminals. The control process for both the indoor and outdoor units is similar to that in the first scenario and will not be elaborated upon here.

[0112] In the third scenario, both the indoor and outdoor units use a 24V non-communication connection. The indoor unit has three 24V power signal interfaces: High (G3), Medium (G2), and Low (G1), which are connected to the thermostat's active power signal interfaces G3, G2, and G1, respectively. The outdoor unit has three 24V power signal interfaces: High (Y3), Medium (Y2), and Low (Y1), which are connected to the thermostat's active power signal interfaces Y3, Y2, and Y1, respectively.

[0113] like Figure 11 As shown, after the unit starts operating, if the indoor ambient temperature is greater than the thermostat set temperature + t℃ during cooling, and less than the thermostat set temperature - t℃ during heating, the unit outputs its maximum capacity. The thermostat sends a 24V power signal for high-speed operation to both the indoor and outdoor units (a 24V power signal is also output at medium and low fan speeds). The indoor unit operates at high fan speed, and the outdoor unit operates at a preset high frequency (generally the highest frequency corresponding to the outdoor ambient temperature). If the thermostat set temperature is less than the indoor ambient temperature and less than the thermostat set temperature + t℃ during cooling, and less than the indoor ambient temperature and less than the thermostat set temperature during heating, the thermostat sends a 24V power signal for medium-speed operation to both the indoor and outdoor units (a 24V power signal is also output at low fan speed, but not at high speed). The outdoor unit operates at a preset medium frequency (different medium frequencies are preset for different outdoor ambient temperatures; the compressor frequency can also be controlled by a preset target pressure, adjusting the compressor frequency so that the pressure sensed by the pressure sensor matches the preset target pressure), and the indoor unit operates at medium fan speed. If the indoor ambient temperature is less than the thermostat's set temperature during cooling, and greater than the set temperature during heating, the thermostat sends a 24V power signal to both the indoor and outdoor units (no 24V power signal is output for medium to high settings). The outdoor unit operates at the lowest frequency corresponding to the outdoor ambient temperature, and the indoor unit operates at a low fan speed. When the unit stops running, the thermostat will no longer send G3 / G2 / G1 / Y1 / Y2 / Y3 signals, and the indoor and outdoor units will stop if they do not receive the corresponding setting signal. 't' is the preset temperature difference value, which can be set to 3℃ by default and then changed according to user needs.

[0114] In all three implementation methods described above, the outdoor unit and thermostat communicate with each other via either a communication method or a 24V non-communication method to transmit indoor temperature and set temperature information to the outdoor unit. The outdoor unit can then adjust its output based on this information, preventing frequent temperature-point shutdowns. The indoor unit, outdoor unit, and thermostat still use a 24V non-communication control method, which can also be used to adjust the indoor unit's airflow to match the outdoor unit's operation. The outdoor unit of this system can still be used with indoor units from different brands. All three methods allow the outdoor unit to be compatible with different brands of indoor units while meeting the user's need to replace only the outdoor unit when upgrading. Furthermore, the system can adjust the unit according to cooling and heating capacity requirements, solving problems such as frequent temperature-point shutdowns leading to energy waste and poor operating noise.

The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more air conditioning equipment control device embodiments provided below can be found in the limitations of the air conditioning equipment control method described above, and will not be repeated here.

[0117] In one embodiment, such as Figure 12 As shown, an air conditioning equipment control device is provided, implemented based on any of the above embodiments of an air conditioning equipment, including a temperature acquisition module 1202 and a working adjustment module 1204, wherein:

[0118] Temperature acquisition module 1202 is used to acquire indoor ambient temperature and thermostat set temperature;

[0119] The working adjustment module 1204 is used to send a power signal to the corresponding passive power signal interface according to the indoor ambient temperature and the temperature set by the thermostat.

[0123] If the indoor ambient temperature is lower than the thermostat set temperature during cooling, or higher than the thermostat set temperature during heating, a power signal is sent to a third number of passive power signal interfaces in a device; the first number is greater than the second number, and the second number is greater than the third number.

[0126] The rate of change of the operating frequency of devices with communication connections is adjusted according to the rate of change of indoor ambient temperature.

[0127] In one embodiment, the operation adjustment module is further configured to stop sending power signals to the passive power signal interface if the air conditioning equipment stops operating.

[0128] Each module in the aforementioned air conditioning equipment control device can be implemented entirely or partially through software, hardware, or a combination thereof.
