The air-conditioning linkage control system provided according to the embodiment of the present application, please refer to Figure 3 , includes an air conditioner 100, a water heater 102, a first temperature sensor 106, a second temperature sensor 108, a humidity sensor 110, a controller, etc.

The air conditioner 100 includes a compressor, a heat exchange component, a heating component, etc., is suitable for installation in a bathroom, and can change the temperature and humidity in the bathroom. During use, users can adjust the operating mode of the air conditioner through buttons or remote control devices.

The water heater 102 is suitable for installation in the bathroom. The water heater 102 includes a shower 104, a temperature adjustment component, a water storage tank, etc. The water storage tank is installed at a higher position in the bathroom to allow the hot water to be automatically discharged under the action of gravity. The temperature adjustment component can Adjust the water temperature of the shower head 104 to ensure user comfort.

The first temperature sensor 106 is connected to the shower head 104 of the water heater 102 and can obtain the outlet water temperature of the water heater 102 . The second temperature sensor 108 is suitable for installation in the bathroom and is used to obtain the ambient temperature in the bathroom. The humidity sensor 110 is suitable for installation in the bathroom and is used to obtain the relative humidity in the bathroom.

It should be noted that the first temperature sensor 106, the second temperature sensor 108 and the humidity sensor 110 can be of appropriate models and specifications as required.

The controller signal is connected to the air conditioner 100, the water heater 102, the first temperature sensor 106, the second temperature sensor 108 and the humidity sensor 110, and can obtain the environmental temperature information, relative humidity information and outlet water temperature information of the water heater 102 in the bathroom, and adjust the temperature according to the environment. The temperature, relative humidity and outlet water temperature are used to determine the fogging risk status in the bathroom, and then the air conditioner 100 is controlled to perform dehumidification, and then the air conditioner 100 is linked with the water heater 102 or shower head 104.

It should be noted that the controller can be an independent control device and can be connected to the air conditioner 100, water heater 102, first temperature sensor 106, and second temperature sensor through wired or wireless (including Bluetooth signal, infrared signal, WiFi signal, etc.) 108 and the humidity sensor 110, thereby realizing the linkage between the water heater 102 and the air conditioner 100, and dehumidifying according to the environmental conditions in the bathroom.

The controller can also be integrated with the control module of the air conditioner 100. The air conditioner 100 serves as the center of environmental control in the bathroom, receiving environmental information and controlling the operation of the compressor, heat exchange components, heating components, etc.

In some embodiments, the water heater 102 also includes an auxiliary heat and air supply component 112. The auxiliary heat and air supply component 112 is signal-connected to the controller. The auxiliary heat and air supply component 112 can be linked with the air conditioner 100 to provide auxiliary heating for the bathroom.

According to the air conditioning linkage control system provided by the embodiment of the present application, the first temperature sensor 106 is installed at the shower head 104 of the water heater 102 to obtain the outlet water temperature of the water heater 102 .

In some cases, the shower head 104 has a built-in wireless connection module, which can directly transmit signals to the air conditioner 100 through Bluetooth, WiFi, etc., thereby realizing linkage between the air conditioner 100 and the shower head 104. In this case, the shower head 104 has a built-in battery unit that can provide power for the wireless connection module and the first temperature sensor 106.

In other embodiments, the first temperature sensor 106 is signal-connected to a control module built into the water heater 102. The water heater 102 can transmit signals with the air conditioner 100 through Bluetooth, WiFi, etc., thereby realizing linkage between the air conditioner 100 and the water heater 102.

According to the air-conditioning linkage control system provided by the embodiment of the present application, the air-conditioning 100 can automatically adjust its own dehumidification mode according to the ambient temperature, relative humidity and water outlet temperature of the water heater in the bathroom, thereby avoiding fogging in the bathroom and avoiding mirrors in the bathroom. Water droplets condense on the walls and glass doors to prevent mildew in the bathroom.

In some embodiments, the shower head 104 is provided with buttons or a control unit, and the user can manually control the operation of the air conditioner 100 to adjust the humidity and temperature in the bathroom.

It is understandable that different users have different experiences when washing, and they also have different requirements for dehumidification in the bathroom. For example, users who are in a hurry to go out will increase the dehumidification efficiency to avoid fogging in the bathroom and affecting their time to organize their instruments. By setting a button or control unit on the shower head 104, the air-conditioning linkage control system can enter the manual control mode, and the user can directly control the air conditioner 100 to enter the dehumidification mode and adjust the dehumidification mode through the shower head 104.

It should be noted that the fogging risk status in the bathroom is related to the ambient temperature, relative humidity and the outlet water temperature of the water heater. The dew point temperature can be determined based on the outlet water temperature and relative humidity, and then the fogging risk status can be determined based on the difference between the ambient temperature and the dew point temperature. , and then adjust the dehumidification mode of the air conditioner 100 according to the fogging risk status in the bathroom.

When the compressor of the air conditioner 100 operates at different frequencies, the heat exchange capabilities of the compressor are different. The higher the operating frequency of the compressor, the higher the condensation rate of water vapor in the bathroom and the higher the dehumidification efficiency. Therefore, controlling the operating frequency of the compressor can adjust the dehumidification efficiency.

In some embodiments, the fogging risk state is a continuous value X, the dehumidification efficiency is a continuous value Y, and the two satisfy a linear functional relationship.

In other embodiments, the fogging risk status is divided into different levels, including a very prone to fogging state, an easy to fogging state, a not prone to fogging state, etc., and the dehumidification mode of the air conditioner can be adjusted for different fogging risk states.

The air conditioning linkage control method provided according to the embodiment of the present application, please refer to Figures 1 to 2, includes:

S100: Obtain the ambient temperature, relative humidity and outlet water temperature of the water heater in the bathroom.

It can be understood that the first temperature sensor 106, the second temperature sensor 108 and the humidity sensor 110 are provided in the bathroom. The first temperature sensor 106 is installed at the shower head 104 of the water heater 102 and can obtain the temperature of the water outlet from the shower head 104. The second temperature sensor 108 is disposed on the top or wall of the bathroom to obtain the ambient temperature in the bathroom. The humidity sensor 110 is disposed on the top or wall of the bathroom to obtain the relative humidity in the bathroom.

S200. Determine a fogging risk state according to the ambient temperature, the relative humidity, and the outlet water temperature.

It can be understood that under certain temperature conditions, water and water vapor in a closed bathroom are in a state of dynamic equilibrium, and the water outlet temperature of the water heater, the relative humidity in the bathroom, and the ambient temperature all have an effect on the condensation of water vapor. When the outlet water temperature is higher, water molecules are more active, which can increase the relative humidity in the bathroom. There is always a dynamic balance between water vapor and water. When the ambient temperature in the bathroom changes, such as a lower temperature, it will directly affect the balance of water vapor, resulting in an increased risk of fogging in the bathroom. Taking into account the ambient temperature, relative humidity and outlet water temperature of the water heater in the bathroom, the fogging risk status in the bathroom can be determined.

S300: Control the air conditioner to perform dehumidification according to the fogging risk state.

It is understandable that adjusting the dehumidification mode of the air conditioner according to different fogging risk states can not only achieve efficient dehumidification, but also avoid problems such as energy waste or low dehumidification efficiency.

According to the air conditioner linkage control method provided by the embodiment of the present application, the air conditioner 100 can dehumidify according to the fogging risk status in the bathroom, and can discharge the water vapor in the bathroom in time, avoiding condensation of water droplets on mirrors, walls and glass doors in the bathroom. Avoid mildew in the bathroom. At the same time, the air conditioner 100 can adjust the dehumidification mode according to the fogging risk status, thereby reducing energy consumption while ensuring efficient dehumidification. The air conditioner 100 is linked with the water heater 102 or the shower head 104 to automatically realize dehumidification in the bathroom.

In some embodiments, the fogging risk status is determined based on ambient temperature, relative humidity, and outlet water temperature, including:

S210. Determine the dew point temperature according to the outlet water temperature and the relative humidity.

It can be understood that when the outlet water temperature of the water heater 102 changes, the dynamic balance of water vapor and water in the bathroom changes, and the dew point temperature of the water vapor also changes. The higher the outlet water temperature, the more active the movement of water molecules, and the higher the dew point temperature.

S222. When it is determined that the difference between the ambient temperature and the dew point temperature is less than the first temperature threshold, the fogging risk state is an extremely prone to fogging state.

S224. When it is determined that the difference between the ambient temperature and the dew point temperature is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, the fogging risk state is a prone to fogging state.

S226: When it is determined that the difference between the ambient temperature and the dew point temperature is greater than the second temperature threshold, the fogging risk state is a state where fogging is difficult.

When the water vapor content in the bathroom remains constant and the air pressure is kept constant, the temperature when the air is cooled to saturation is called the dew point temperature, or dew point for short, and the unit is expressed in ℃ or ℉. In fact, it is the temperature at which water vapor and water reach equilibrium. The difference between the ambient temperature and the dew point temperature indicates the degree of saturation of the air. When the ambient temperature is greater than the dew point temperature, it means that the water vapor content in the air is not saturated. When the ambient temperature is equal to the dew point temperature, it means that the water vapor content in the air is saturated. When the ambient temperature is greater than the dew point temperature, it means that the water vapor content in the air is saturated. When the temperature is lower than the dew point temperature, it means that the water vapor content in the air is saturated.

From the above, it can be seen that the saturation status of water vapor in the bathroom can be determined based on the difference between the ambient temperature and the dew point temperature, and then the risk status of fogging in the bathroom can be determined. Assuming that the difference between the ambient temperature and the dew point temperature is K, the value of K indicates the risk status of water vapor fogging in the bathroom.

Assuming that the first temperature threshold is -2°C and the second temperature threshold is 2°C, the following relationship exists:

When K＜-2℃, the fogging risk state in the bathroom is determined to be extremely prone to fogging; when -2℃≤K≤2℃, the fogging risk state in the bathroom is determined to be prone to fogging; when 2 When ℃＜K, the fogging risk state in the bathroom is determined to be a state where fogging is unlikely.

In other embodiments, the first temperature threshold and the second temperature threshold can be set according to the structure in the bathroom. For example, when the area of glass or mirror is large, the values of the first temperature threshold and the second temperature threshold can be appropriately adjusted.

In some embodiments, controlling the air conditioner to perform dehumidification according to the fogging risk status includes:

S302. When the fogging risk state is the extremely prone to fogging state, control the air conditioner to operate in the first dehumidification mode.

S304. When the fogging risk state is the fogging-prone state, control the air conditioner to operate in the second dehumidification mode.

S306. When the fogging risk state is the difficult-to-fog state, control the air conditioner to operate in the third dehumidification mode.

It can be understood that when the compressor of the air conditioner 100 operates at different frequencies, the heat exchange capabilities of the compressor are different. The higher the operating frequency of the compressor, the lower the temperature of the heat exchange component, and the higher the condensation rate of water vapor in the bathroom. The condensed water vapor forms droplets and is discharged. The more obvious the dehumidification effect in the bathroom, that is, the higher the dehumidification efficiency. , so controlling the operating frequency of the compressor can adjust the dehumidification efficiency.

In the first dehumidification mode, the compressor of the air conditioner 100 operates at a frequency of 60Hz to 80Hz and enters the powerful dehumidification mode.

In the second dehumidification mode, the compressor of the air conditioner 100 operates at a frequency of 40Hz to 60Hz and enters the normal dehumidification mode.

In the third dehumidification mode, the compressor of the air conditioner 100 operates at a frequency of 20Hz to 40Hz and enters the light dehumidification mode.

It should be noted that under different dehumidification modes, the operating frequency of the compressor can be adjusted as needed to ensure that the water vapor in the bathroom is discharged in time.

In other embodiments, there is a linear relationship between the risk state of fogging in the bathroom and the operating frequency of the compressor.

It can be understood that as the risk of fogging in the bathroom increases, the air conditioner 100 and the water heater 102 or the shower head 104 are linked to adjust the dehumidification mode of the air conditioner 100 in a targeted manner, and the water vapor in the bathroom can be discharged in a timely manner to avoid the problem of mist in the bathroom. Water droplets condense on interior mirrors, walls and glass doors to prevent mildew in the bathroom. At the same time, the air conditioner 100 can automatically adjust the dehumidification mode according to the fogging risk status, reducing energy consumption while ensuring efficient dehumidification.

In some embodiments, controlling the air conditioner to perform dehumidification according to the fogging risk status also includes:

S232: When it is determined that the difference between the ambient temperature and the outlet water temperature is less than or equal to the third temperature threshold, control the air conditioner to operate in a rapid heating mode.

S234: When it is determined that the difference between the ambient temperature and the outlet water temperature is greater than the third temperature threshold, control the air conditioner to perform dehumidification according to the fogging risk state.

It can be understood that the linkage between the air conditioner 100 and the water heater 102 or the shower head 104 can reduce the risk of fogging in the bathroom and improve the user's comfort when washing. During dehumidification, if the temperature in the bathroom is low, the user experience will be degraded.

In some embodiments, the preset third temperature threshold is -10°C, and the difference between the ambient temperature and the outlet water temperature is L.

When L ≤ -10°C, it indicates that the temperature in the bathroom is low, and the air conditioner 100 is controlled to operate in the rapid heating mode, which can quickly increase the ambient temperature in the bathroom, avoid the user from catching a cold, and improve the user experience.

When L>-10°C, it indicates that the temperature in the bathroom is acceptable, and the air conditioner 100 is controlled to perform dehumidification according to the established plan.

It should be noted that the value of the third temperature threshold can be set according to the user's personal experience. When the value of the third temperature threshold is larger, the air conditioner 100 will operate in the rapid heating mode only when the ambient temperature is low and is more sensitive to cold. Users can appropriately adjust the third temperature threshold to ensure that the bathroom is in a warm state.

When it is determined that the difference between the ambient temperature and the outlet water temperature is greater than the third temperature threshold, the air conditioner 100 performs dehumidification according to a preset plan. At the same time, the difference between the ambient temperature and the outlet water temperature is continuously monitored. When the difference between the ambient temperature and the outlet water temperature is less than or equal to the third temperature threshold again, the air conditioner 100 is controlled to run in the rapid heating mode again.

S242: When it is determined that the difference between the ambient temperature and the outlet water temperature is less than or equal to the third temperature threshold, control the air conditioner to operate in a rapid heating mode.

S244: When it is determined that the difference between the ambient temperature and the outlet water temperature is greater than the third temperature threshold, control the air conditioner to operate in a constant temperature dehumidification mode.

It can be understood that when it is determined that the difference between the ambient temperature and the outlet water temperature is greater than the third temperature threshold, the air conditioner 100 continues to dehumidify. At this time, the temperature in the bathroom may drop, thereby reducing the user's experience. The constant temperature dehumidification mode means that the air conditioner 100 turns on the dehumidification mode and the heating mode at the same time, controls the operation of the compressor to dehumidify the bathroom, and controls the operation of the heating component to heat the bathroom. When the air conditioner 100 operates in the constant temperature dehumidification mode, it can not only perform dehumidification, but also ensure that the bathroom is at a constant temperature.

In some embodiments, controlling the air conditioner to operate in a constant temperature dehumidification mode also includes:

S246: When it is determined that the difference between the ambient temperature and the outlet water temperature is less than or equal to the third temperature threshold again, control the air conditioner to operate in a fourth dehumidification mode.

It can be understood that when the air conditioner 100 operates in the constant temperature dehumidification mode, the heat generated by the air conditioner 100 during heating is greater than or equal to the heat taken away during cooling, thereby keeping the bathroom in a constant temperature state. During use, users may open and close the bathroom door, take clothes, etc., causing the temperature in the bathroom to drop. Continuously monitor the difference between the ambient temperature and the outlet water temperature. When it is determined that the difference between the ambient temperature and the outlet water temperature is less than or equal to the third temperature threshold again, it means that the temperature in the bathroom has dropped. At this time, the air conditioner 100 is controlled to operate in the fourth dehumidification mode to reduce the temperature. The cooling capacity of the air conditioner is 100.

It should be noted that the fourth dehumidification mode is a low-frequency dehumidification mode. The operating frequency of the compressor is between 10Hz and 20Hz. The compressor can also cooperate with the electronic expansion valve to quickly open, so that the actual cooling capacity of the air conditioner 100 due to the dehumidification mode is less than the heating capacity. The heating capacity of the component is achieved to achieve heating/constant temperature dehumidification.

S252: When it is determined that the difference between the ambient temperature and the outlet water temperature is greater than the third temperature threshold, control the auxiliary heating and air supply component to heat the bathroom.

It can be understood that when it is determined that the difference between the ambient temperature and the outlet water temperature is greater than the third temperature threshold, the temperature in the bathroom is more suitable. At this time, the air conditioner 100 is controlled to perform dehumidification. Dehumidification will cause the temperature in the bathroom to drop.

When controlling the air conditioner 100 for dehumidification, the auxiliary heat and air supply component 112 of the water heater 102 is turned on, the air conditioner 100 turns on the dehumidification mode, and the auxiliary heat and air supply component 112 turns on the heating mode, which can reduce the humidity in the bathroom and avoid fogging, while also ensuring that the bathroom The interior is at a constant temperature, improving user comfort.

S260: Manually control the air conditioner to perform dehumidification according to the fogging risk state.

It can be understood that the shower head 104 is provided with buttons or a control unit, and the user can manually control the operation of the air conditioner 100 . Different users have different experiences when washing, and they also have different dehumidification requirements in the bathroom. For example, users who are in a hurry to go out will increase the dehumidification power to avoid fogging in the bathroom and affecting their time to organize their instruments. By setting a button or control unit on the shower head 104, the air-conditioning linkage control system can enter the manual control mode, and the user can directly control the air conditioner 100 to enter the dehumidification mode and adjust the dehumidification mode through the shower head 104. In the same way, users can also manually control the ambient temperature in the bathroom to ensure that the ambient temperature is in a comfortable state.

In some embodiments, controlling the air conditioner to perform dehumidification according to the fogging risk state further includes:

S410. When it is determined that the time period for the water heater to stop discharging water is less than a preset time period, control the air conditioner to continue dehumidification.

S420: When it is determined that the time period for the water heater to stop discharging water is greater than or equal to the preset time period, control the air conditioner to stop dehumidification.

It is understandable that the user may turn on and off the water heater 102 multiple times when washing to complete operations such as body moistening, detergent application, and body washing. The shower head 104 is turned on when water is needed and turned off when water is not needed. When the water heater 102 stops discharging water intermittently, it can be determined that the user has not completed washing, and the air conditioner 100 should keep operating in the dehumidification mode. After the user finishes washing, the water heater 102 stops water output and the air conditioner 100 turns off the dehumidification mode to save energy consumption. During use, it can be determined whether the user has finished washing based on the time the water heater 102 stops discharging water.

The timer starts after the water heater 102 stops discharging water. If the water heater 102 discharges water again within the preset time period, it means that the user is still in the washing state. At this time, the air conditioner 100 is controlled to operate in the dehumidification mode. When the water heater 102 stops discharging water for longer than or equal to the preset time, it indicates that the user has finished washing and there is no need to continue dehumidification in the bathroom. The air conditioner 100 is controlled to automatically stop dehumidification to reduce energy consumption. The air conditioner 100 can automatically control the startup and shutdown of the dehumidification mode. It has a high level of intelligence and is more convenient for users to use.

It should be noted that whether the water heater 102 discharges water and the duration of stopping the water discharge can be determined by detecting the flow rate of the drainage pipe. It can also be determined by using components such as the valve of the shower 104 to determine whether the water heater 102 discharges water and the duration of stopping the water discharge. When the water heater 102 does not produce water, the air conditioner 100 does not perform dehumidification and does not exit the dehumidification mode.

In some embodiments, determining that the time period for which the water heater 102 stops discharging water is greater than or equal to a preset time period also includes:

S430. When it is determined that the ambient temperature is less than or equal to the fourth temperature threshold, control the air conditioner to run in the rapid heating mode.

It can be understood that when the water heater 102 stops water for longer than or equal to the preset time, it indicates that the user has finished washing. If the ambient temperature is low at this time, for example, lower than 20°C, the air conditioner 100 is controlled to run in the rapid heating mode to quickly improve the bathroom. The temperature inside the device prevents users from catching colds and improves the user experience.
