Referring to fig. 2, in an embodiment of the humidity detection method of the present invention, the humidity detection method includes the following steps:
step S10, acquiring the refrigerant inlet temperature of an indoor heat exchanger in the air conditioner refrigeration mode, the fan operation parameters and the indoor environment temperature in the action space of the air conditioner;
step S20, determining the dew point temperature corresponding to the air conditioner acting space according to the refrigerant inlet temperature and the fan operation parameters;
and step S30, determining the relative humidity in the action space according to the dew point temperature and the indoor environment temperature.
In this embodiment, when the air conditioner operates in the cooling mode, the temperature of the refrigerant inlet of the indoor heat exchanger of the air conditioner may be obtained after the air conditioner stably operates. The air conditioner is provided with a temperature detection sensor between the throttling component and the refrigerant inlet of the indoor heat exchanger, so that the temperature of the refrigerant inlet of the indoor heat exchanger in the refrigeration mode of the air conditioner can be obtained based on the temperature sensor. The fan operation parameter may include a current operating wind speed level of the air conditioner or a fan rotation speed.
Specifically, the temperature detection sensor can be set to a thermal bulb, and the thermal bulb is in communication connection with a processor of the air conditioner, so that the processor can acquire the temperature of a refrigerant inlet at the refrigerant inlet of the indoor heat exchanger at regular time through the thermal bulb. Alternatively, the processor may control the thermal bulb to continuously detect a refrigerant inlet temperature at a refrigerant inlet of the indoor heat exchanger.
For example, the temperature detection sensor may be provided with a thermistor such that the thermistor may change a resistance value according to a temperature change at a refrigerant inlet of the indoor heat exchanger. So that the voltage value corresponding to the thermistor in the temperature detection circuit changes along with the temperature change. The processor can acquire the voltage value at regular time and then determine a corresponding temperature value according to the voltage value, or can continuously acquire the voltage value to continuously monitor the temperature value.
The fan operation parameters can be directly determined according to the current operation parameters of the air conditioner, and the processor can directly read the fan rotation speed or the wind speed grade of the air conditioner because the processor controls the fan rotation speed or the wind speed grade of the air conditioner. It should be noted that the air conditioner may be provided with an automatic wind mode and a fixed wind mode. When the air conditioner operates in the automatic wind mode, the fan rotating speed or the wind speed grade of the air conditioner can be determined according to an automatic wind calculation rule, and the processor obtains the fan rotating speed or the wind speed grade determined according to the automatic wind calculation rule. When the air conditioner operates in the fixed wind mode, a wind speed level set by a user can be acquired. The corresponding fan speed may also be determined based on a user-set wind speed rating. The mapping relation between the wind speed grade and the rotating speed of the fan is pre-stored data and can be directly read.
In addition, the air conditioner may be further provided with a temperature detection sensor for detecting an indoor ambient temperature in an action space of the air conditioner to acquire the ambient temperature in the action space. The type of the temperature sensor for detecting the ambient temperature of the user is not particularly limited in this embodiment.
Further, after the refrigerant inlet temperature, the fan operating parameter, and the indoor environment temperature are obtained, the dew point temperature in the action space may be determined based on the refrigerant inlet temperature and the fan operating parameter. Wherein the dew point temperature may be calculated according to the following formula:
TL＝TM+A*F
wherein, TLIs the dew point temperature, TMThe refrigerant inlet temperature, A is a dew point calculation factor, and is a fixed constant, F, the fan operating parameter. It is understood that the dew point calculation factor a corresponding to F when the fan speed is set is generally different from the dew point calculation factor a corresponding to F when the wind speed is set to F (or may be the same value in some special cases). In an embodiment, when F is the wind speed level, the value range of the corresponding dew point calculation factor a may be set to 1 to 5, for example, may be set to any one of 1, 2, 3, 4, or 5.
It should be noted that when the air conditioner is operated in the cooling mode, the evaporation temperature (i.e., the refrigerant inlet temperature) of the indoor heat exchanger of the air conditioner is low, and when the dew point temperature in the working space is higher than the evaporation temperature, moisture in the air is automatically precipitated, so that the air humidity in the air is reduced. As the moisture in the air in the action space is continually released, the ambient humidity in the action space is continually reduced. The dew point temperature in the process space also drops continuously as the ambient humidity drops. Whether the moisture in the air in the action space is separated out or not depends on the ambient temperature in the action space, the evaporation temperature of the air conditioner and the air output. When the air conditioner is in a stable state, the indoor environment temperature does not change any more, and the water analysis amount in the action space is in a balanced state. That is, the dew point temperature in the operating space is in equilibrium with the air output and evaporation temperature of the air conditioner. And the air output quantity depends on the fan operation parameters of the air conditioner. Therefore, when the air conditioner is in a steady state, the dew point temperature can be determined based on the evaporation temperature (i.e., the refrigerant inlet temperature) and the fan operation parameter.
After determining the dew point temperature, obtaining a mapping relation between the dew point temperature and the indoor environment temperature and the relative humidity, wherein the mapping relation between the dew point temperature and the indoor environment temperature and the relative humidity can be stored in a storage medium in a form of a table, so that a processor of an air conditioner can directly read the mapping relation. For example, the table corresponding to the dew point temperature and the mapping relationship between the indoor ambient temperature and the relative humidity may be as shown in table 1 below:
Figure BDA0002471962720000091
TABLE 1
In Table 1, TS1、TS2、TS3And TS4For different values of room temperature, TL1And TL2Are different values of dew point temperature, S11、S21、S31、S41、S12、S22、S32And S42Are different values of relative humidity.
Based on the dew point temperature and the mapping relation between the indoor environment temperature and the relative humidity, after the dew point temperature and the indoor environment temperature are determined, the air conditioner can determine the relative humidity in the action space based on the dew point temperature, the indoor temperature and the mapping relation.
In the technical scheme disclosed in this embodiment, a refrigerant inlet temperature of an indoor heat exchanger in a refrigeration mode of an air conditioner, a fan operation parameter and an indoor environment temperature in an action space of the air conditioner are obtained first, then a dew point temperature corresponding to the action space of the air conditioner is determined according to the refrigerant inlet temperature and the fan operation parameter, and finally a relative humidity in the action space is determined according to the dew point temperature and the indoor environment temperature. The relative humidity in the action space of the air conditioner can be determined according to the refrigerant inlet temperature, the fan operation parameters and the indoor environment temperature, so that the air conditioner does not need to acquire the relative humidity in the action space through the humidity detection sensor, and therefore the phenomenon that the humidity detection sensor is damaged to cause obvious deviation between a humidity detection value and actual humidity is avoided, the humidity detection accuracy is poor, and the effect of improving the humidity detection accuracy is achieved. Meanwhile, the air conditioner does not need to acquire the environmental humidity in the action space through the humidity sensor, so that the air conditioner does not need to be provided with an additional humidity sensor specially used for detecting the environmental humidity, and the effect of reducing the production cost of the air conditioner is achieved. In addition, when the humidity detection method provided by the application is applied to an air conditioner provided with a humidity sensor, the relative humidity determined by the humidity detection method can be corrected or corrected based on the description of the invention, so that the effect of improving the humidity detection precision of the air conditioner can be achieved.

step S40, acquiring outdoor environment temperature;
step S50, determining the operation parameters of the air conditioner according to the outdoor environment temperature, the indoor environment temperature and the relative humidity;
and step S60, controlling the air conditioner to operate according to the operation parameters.
In this embodiment, the air conditioner may be provided with a temperature detection sensor for detecting the outdoor ambient temperature to acquire the outdoor ambient temperature based on the temperature detection sensor. The temperature detection sensor may be integrally provided with an outdoor unit of the air conditioner, or may be independently provided outdoors. And/or the air conditioner can also be connected with other equipment with a temperature detection function through the communication module so as to acquire the outdoor environment temperature detected by the other equipment. And/or the air conditioner can also be provided with a network interface, so that the air conditioner can be communicated with a network server, weather information corresponding to the position of the air conditioner is obtained based on the network server, and the outdoor temperature corresponding to the current time point is determined according to the weather information.
After the outdoor temperature is obtained, the operation parameters of the air conditioner can be determined according to the outdoor temperature, the indoor temperature and the similar humidity.
Specifically, after the outdoor temperature, the indoor temperature and the relative humidity are obtained, the operation parameters corresponding to the outdoor temperature, the indoor temperature and the relative humidity can be obtained through a pre-trained neural network model. When the neural network model is trained, a plurality of training data combined by different outdoor temperatures, indoor temperatures and relative humidities can be used for training, and the optimal operation parameters of the energy efficiency performance of the air conditioner are stored as training results under different combinations of the outdoor temperatures, the indoor temperatures and the relative humidities. Therefore, when the air conditioner is determined to be operated by the operation parameters based on the outdoor temperature, the indoor temperature and the relative humidity according to the pre-trained neural network model, the optimal energy efficiency performance of the air conditioner corresponding to the current outdoor temperature, the current indoor temperature and the current relative humidity can be achieved.
In the technical scheme disclosed in this embodiment, the outdoor environment temperature is obtained, the operation parameters of the air conditioner are determined according to the outdoor environment temperature, the indoor environment temperature and the relative humidity, and the air conditioner is controlled according to the operation parameters, so that the effect of improving the control rationality of the air conditioner is achieved.
