Fig. 1 is a schematic diagram of a method for preventing condensation of a fresh air pipe of an air conditioner according to an embodiment of the present disclosure; referring to fig. 1, an embodiment of the present disclosure provides a method for preventing condensation of a fresh air pipe of an air conditioner, including:
s11, under the condition that the air conditioner is started to perform a heating mode and a fresh air mode, the air conditioner obtains the current outdoor temperature, the current dew point temperature and the temperature of the inner pipe wall of the new air pipe.
S12, under the condition that the current outdoor temperature is not higher than the dew point temperature, the air conditioner determines a target operation scheme of an induced draft fan of the air conditioner according to the temperature of the inner pipe wall of the new air pipe.
S13, the air conditioner controls the induced draft fan to execute the target operation scheme.
In the scheme, under the condition that the air conditioner is started to perform a heating mode and a fresh air mode, the air conditioner obtains the current outdoor temperature, the current dew point temperature and the temperature of the inner pipe wall of the new air pipe. Here, the air conditioner may obtain the current outdoor temperature in various ways. In one example, if an air conditioner is associated with an outdoor ambient temperature sensor, temperature information collected by the outdoor ambient temperature sensor may be determined as a current outdoor temperature. In another example, the air conditioner may also obtain the current outdoor temperature through its associated mobile device. Here, the mobile device may include: a cell phone, a smart watch or a smart bracelet. In addition, the air conditioner can also be provided with a temperature sensor at the position where the fresh air pipe enters the room, and the temperature information acquired by the temperature sensor is determined as the temperature of the inner pipe wall of the fresh air pipe.
Further, the air conditioner can judge the magnitude relation between the current outdoor temperature and the dew point temperature after obtaining the current outdoor temperature, the current dew point temperature and the temperature of the inner pipe wall of the fresh air pipe, so as to judge whether the current fresh air pipe has condensation risk. Specifically, the air conditioner can determine that the condensation risk exists under the condition that the current outdoor temperature is not higher than the dew point temperature, so that the target operation scheme of the induced draft fan of the air conditioner is determined by combining the temperature of the inner pipe wall of the new air pipe. In this embodiment, the air conditioner may be provided with an induced draft fan. Here, the draught fan can be arranged at the air outlet of the air conditioner, and under the premise that the draught fan is started, the air blown out from the air outlet of the air conditioner can be introduced into the cladding pipe of the fresh air pipe. Therefore, the hot air blown out from the air outlet of the air conditioner can be more reasonably utilized.
Further, the air conditioner may control the induced draft fan to execute the target operation scheme after determining the target operation scheme of the induced draft fan. It can be understood that under the condition that the air conditioner operates in the heating mode and the fresh air mode, when the air conditioner executes the target operation scheme of the induced draft fan, the induced draft fan of the air conditioner starts to operate according to the target operation scheme, at this moment, the induced draft fan can introduce hot air blown out from the air outlet of the air conditioner into the cladding pipe of the fresh air pipe so as to heat the fresh air pipe through the hot air conveyed into the cladding pipe, and the condensation condition of the fresh air pipe is effectively avoided.
By adopting the method for preventing the fresh air pipe of the air conditioner from condensation, the current outdoor temperature, the current dew point temperature and the temperature of the inner pipe wall of the fresh air pipe are obtained under the condition that the air conditioner is started in a heating mode and a fresh air mode; under the condition that the current outdoor temperature is not higher than the dew point temperature, determining a target operation scheme of the air conditioner induced draft fan according to the temperature of the inner pipe wall of the new air pipe; and controlling the induced draft fan of the air conditioner to execute a target operation scheme. With this scheme, can be under the condition that confirm that there is the condensation hidden danger in the fresh air fan of air conditioner, combine the inner tube wall temperature of new tuber pipe, confirm the target operation scheme who is adapted to the air conditioner draught fan to under the condition that the air conditioner control draught fan carried out target operation scheme, avoid fresh air pipe surface to produce the condensation, also need not additionally to install the heat preservation design on the air conditioner, improved the life of air conditioner when saving air conditioner manufacturing cost, satisfied the user to the control demand of air conditioner.
Optionally, S12, the air conditioner determines a target operation scheme of the induced draft fan of the air conditioner according to the temperature of the inner pipe wall of the new air pipe, including:
under the condition that the temperature of the inner pipe wall of the fresh air pipe is lower than a first temperature threshold value and higher than a second temperature threshold value, the air conditioner determines that the target operation scheme of the induced draft fan is to control the induced draft fan of the air conditioner to operate according to a first gear; under the condition that the temperature of the inner pipe wall of the fresh air pipe is lower than a second temperature threshold value, the air conditioner determines that the target operation scheme of the induced draft fan of the air conditioner is to control the induced draft fan of the air conditioner to operate according to a second gear; wherein the first gear is lower than the second gear.
In the scheme, the air conditioner can judge the condensation risk of the new air pipe by combining the temperature of the inner pipe wall of the new air pipe, and determine the target operation scheme suitable for the induced draft fan of the air conditioner by combining the condensation risk of the new air pipe. Specifically, the first temperature threshold value and the second temperature threshold value may be preferentially determined, where the first temperature threshold value=the current dew point temperature+3, and the second temperature threshold value=the current dew point temperature+1; for example, if the current dew point temperature is 2 ℃, the first temperature threshold is 5 ℃ and the second temperature threshold is 3 ℃. In this embodiment, under the condition that the temperature of the inner pipe wall of the fresh air pipe is lower than the first temperature threshold and higher than the second temperature threshold, it can be determined that the air conditioner fresh air pipe has lower condensation risk, and the air conditioner can determine that the target operation scheme of the induced draft fan is to control the induced draft fan of the air conditioner to operate according to the first gear, so that hot air blown out from the air outlet of the air conditioner can be blown into the cladding pipe of the fresh air pipe at a lower speed, and the fresh air pipe is heated by a small amount of hot air conveyed into the cladding pipe, so that the condensation on the surface of the fresh air pipe is avoided. Under the condition that the temperature of the inner pipe wall of the fresh air pipe is lower than a second temperature threshold value, the air conditioner can determine that the fresh air pipe of the air conditioner has higher condensation risk, and the air conditioner can determine that the target operation scheme of the induced draft fan of the air conditioner is to control the induced draft fan of the air conditioner to operate according to a second gear. As one example, an air conditioner induced draft fan may include two operating gears. I.e. a first gear and a second gear. And the first gear is lower than the second gear. Like this, can blow the hot-blast cladding pipe of fresh air pipe with higher speed with the hot-blast that blows out of air conditioner air outlet department to this can transport the hot-blast cladding pipe with the hot-blast that blows out of air conditioner air outlet department as early as possible in, in order to heat the fresh air pipe in time, avoid the fresh air pipe surface to produce the bad experience that the condensation brought for the user.
Optionally, under the condition that the temperature of the inner pipe wall of the fresh air pipe is higher than a third temperature threshold, the air conditioner determines that the target operation scheme of the induced draft fan is to turn off the air conditioner induced draft fan; wherein the third temperature threshold is higher than the first temperature threshold.
In this scenario, the third temperature threshold is higher than the first temperature threshold. Here, the third temperature threshold=the current dew point temperature+4. For example, if the current dew point temperature is 2 ℃, the third temperature threshold is 6 ℃. Specifically, after the air conditioner controls the induced draft fan to execute the target operation scheme, the condensation risk which does not exist in the air conditioner new air pipe can be determined under the condition that the temperature of the inner pipe wall of the new air pipe is higher than the third temperature threshold value, and then the air conditioner determines that the target operation scheme of the induced draft fan is to turn off the air conditioner induced draft fan. Therefore, the closing time of the induced draft fan of the air conditioner can be more accurately determined, and unnecessary electric power resource waste is avoided under the condition that the new air pipe of the air conditioner does not have condensation risk.
FIG. 2 is a schematic diagram of a method for obtaining dew point temperature provided by an embodiment of the present disclosure; referring to fig. 2, S11, the air conditioner obtains a current dew point temperature, including:
s21, the air conditioner obtains the current indoor temperature and the current relative humidity.
S22, the air conditioner calculates the current dew point temperature according to the current indoor temperature and the current relative humidity.
In this scheme, the air conditioner can also obtain the current indoor temperature and the current relative humidity through its associated ambient temperature sensor or mobile device. It will be appreciated that the dew point temperature is not the same at different ambient temperatures and humidity. Therefore, the air conditioner can calculate the current dew point temperature by combining the current indoor temperature and the current relative humidity after obtaining the current indoor temperature and the current relative humidity. Therefore, the dew point temperature can be obtained more accurately by combining the current temperature and humidity, and an accurate data basis is provided for the judging process of the dew condition of the fresh air fan.
Optionally, S22, the air conditioner calculates a current dew point temperature according to the current indoor temperature and the current relative humidity, including:
in this scheme, T d The current dew point temperature, b is a first influencing factor, RH is the current relative humidity, a is a second influencing factor, and T is the current indoor temperature. And γ (T, RH) can be calculated by the following formula:
the first influencing factor b is 237.7 ℃ and the second influencing factor a is 17.27. In this way, the current indoor temperature and the current relative humidity can be input into the calculation formula of the dew point temperature, and the dew point temperature can be obtained more accurately.
FIG. 3 is a schematic diagram of another method for preventing condensation of a fresh air duct of an air conditioner according to an embodiment of the present disclosure; as shown in fig. 3, an embodiment of the present disclosure further provides a method for preventing condensation of a fresh air pipe of an air conditioner, including:
s31, under the condition that the air conditioner is started to perform a heating mode and a fresh air mode, the air conditioner obtains the current outdoor temperature, the current dew point temperature and the temperature of the inner pipe wall of the new air pipe.
S32, under the condition that the current outdoor temperature is higher than the dew point temperature and the temperature of the inner pipe wall of the fresh air pipe is lower than the dew point temperature, the air conditioner pushes fault reminding to the associated user.
In the scheme, after the air conditioner obtains the current outdoor temperature, the current dew point temperature and the temperature of the inner pipe wall of the new air pipe, the magnitude relation of the outdoor temperature, the dew point temperature and the temperature of the inner pipe wall of the new air pipe can be judged. Specifically, under the condition that the current outdoor temperature is higher than the dew point temperature and the temperature of the inner pipe wall of the fresh air pipe is lower than the dew point temperature, the current fresh air pipe is determined to have the condensation risk, and the condensation risk is not caused by the fact that the outdoor temperature is lower, so that the air conditioner can push a fault reminder to an associated user. Here, the fault reminder may be pushed to its associated user by text push or voice push. Therefore, the user can be warned of the occurrence of faults of the air conditioner under the condition that the current fresh air pipe is determined to have the condensation risk which is not caused by lower outdoor temperature, and the occurrence of more serious adverse effects is avoided.
FIG. 4 is a schematic diagram of another method for preventing condensation of a fresh air duct of an air conditioner according to an embodiment of the present disclosure; as shown in fig. 4, an embodiment of the present disclosure further provides a method for preventing condensation of a fresh air pipe of an air conditioner, including:
s41, the air conditioner acquires the current inner pipe wall temperature.
S42, under the condition that the current time length of the inner pipe wall temperature lower than the fourth temperature threshold value lasts for a preset time length, the air conditioner controls the air conditioner to close the fresh air fan baffle plate so as to prevent outdoor cold air from continuously entering a room.
In the scheme, after the air conditioner controls the induced draft fan to execute the target operation scheme, the air conditioner can acquire the current inner pipe wall temperature, so that the current condensation condition of the new air pipe can be judged through the acquired inner pipe wall temperature again. Further, under the condition that the current time length that the temperature of the inner pipe wall is lower than the fourth temperature threshold value is continuously preset time length, after the air conditioner is determined to operate the induced draft fan according to the target operation scheme, the condensation condition of the fresh air fan is not improved, and then the air conditioner can be controlled to close the fresh air fan baffle. Here, the fourth temperature threshold = current dew point temperature-1; the preset time period may be 10 minutes. Therefore, outdoor cold air can be prevented from continuously entering the room, and the condensation condition of the fresh air pipe is aggravated.
Optionally, after the air conditioner controls the air conditioner to close the fresh air fan baffle, the induced draft fan and the fresh air fan can be reset periodically.
