The mobile device may include, for example, a cell phone, smart home device, wearable device, smart mobile device, virtual reality device, etc., or any combination thereof, wherein the wearable device includes, for example: smart watches, smart bracelets, pedometers, etc.

In the embodiment of the disclosure, the oil temperature superheat represents the difference between the oil sump temperature at the bottom of the compressor and the high pressure value. Wherein the high pressure value represents a saturation temperature value corresponding to the exhaust pressure value. The discharge pressure can be detected by installing a pressure sensor on the discharge pipe of the air conditioner.

As shown in fig. 1, an embodiment of the present disclosure provides a control method for an air conditioner, including:

s01, the air conditioner obtains the oil temperature superheat degree of a compressor of the air conditioner in a refrigeration mode.

S02, regulating and controlling the rotating speed value of the outdoor fan and/or the indoor fan under the condition that the overheat degree of the oil temperature does not meet the oil temperature condition.

By adopting the control method for the air conditioner, when the superheat degree of the oil temperature does not meet the oil temperature condition, the rotating speed value of the outdoor fan is reduced, and the exhaust pressure value is increased. Accordingly, the high-pressure value increases. At the same time, the sump temperature also increases. The temperature rising rate of the oil pool temperature is higher than that of the high-pressure value, so that the overheat degree of the oil temperature tends to increase. When the superheat degree of the oil temperature does not meet the oil temperature condition, the rotating speed value of the indoor fan is increased, so that the evaporation efficiency of the indoor heat exchanger is increased. Accordingly, the high-pressure value increases and the oil sump temperature also increases and the temperature rise rate of the oil sump temperature is higher than that of the high-pressure value, resulting in a corresponding tendency of increasing the degree of superheat of the oil temperature. Therefore, the oil temperature superheat degree of the compressor can be regulated and controlled when the air conditioner operates in a refrigerating mode by regulating and controlling the rotating speed of the outdoor fan and/or the indoor fan, and the operation reliability of the air conditioner in the refrigerating mode is improved.

Optionally, referring to fig. 2, when the superheat degree of the oil temperature does not meet the oil temperature condition, the air conditioner regulates the rotation speed value of the outdoor fan and/or the indoor fan, including:

s11, the air conditioner reduces the rotating speed value of the outdoor fan at a first preset change rate under the condition that the overheat degree of the oil temperature does not meet the oil temperature condition.

In the step, after the air conditioner reduces the rotation speed value of the outdoor fan at a first preset change rate, the air conditioner can judge whether the oil temperature superheat degree meets the oil temperature condition again at intervals of a first preset time length. If the oil temperature superheat degree still does not meet the oil temperature condition, the air conditioner reduces the rotating speed value of the outdoor fan according to the first preset change rate until the oil temperature superheat degree meets the oil temperature condition. The first preset change rate can be determined according to the model of the air conditioner. As an example, the first preset rate of change is 30 revolutions per minute or 50 revolutions per minute.

S12, the air conditioner re-acquires the new oil temperature superheat degree, and increases the rotating speed value of the indoor fan at a second preset change rate under the condition that the new oil temperature superheat degree does not meet the oil temperature condition.

In the step, after the air conditioner increases the rotation speed value of the indoor fan at the second preset change rate, the air conditioner can judge whether the oil temperature superheat degree meets the oil temperature condition again at intervals of a second preset time length. If the oil temperature superheat degree still does not meet the oil temperature condition, the air conditioner increases the rotating speed value of the indoor fan according to a second preset change rate until the oil temperature superheat degree meets the oil temperature condition. The second preset change rate can be determined according to the model of the air conditioner. As an example, the second preset rate of change is 20 revolutions per minute or 30 revolutions per minute.

Thus, the accurate regulation and control of the superheat degree of the oil temperature is realized by carrying out gradient regulation and control on the outdoor fan and the indoor unit fan.

Optionally, referring to fig. 3, when the superheat degree of the oil temperature does not meet the oil temperature condition, the air conditioner regulates the rotation speed value of the outdoor fan and/or the indoor fan, including:

s21, the air conditioner reduces the rotating speed value of the outdoor fan at a first preset change rate under the condition that the overheat degree of the oil temperature does not meet the oil temperature condition.

S22, the air conditioner obtains the current outdoor fan rotating speed value of the outdoor fan.

S23, the air conditioner acquires new oil temperature superheat degree again under the condition that the current outdoor fan rotating speed value is matched with the rotating speed lower limit value of the outdoor fan.

In this step, the current rotation speed value of the outdoor fan is matched with the rotation speed lower limit value of the outdoor fan, which may be that the current rotation speed value of the outdoor fan is smaller than or equal to the rotation speed lower limit value of the outdoor fan, or that the current rotation speed value of the outdoor fan is located in a preset rotation speed range corresponding to the rotation speed lower limit value of the outdoor fan.

And S24, when the new oil temperature superheat degree does not meet the oil temperature condition, the air conditioner increases the rotating speed value of the indoor fan at a second preset change rate.

Therefore, the rotating speed value of the outdoor fan has a certain regulation and control range, and if the rotating speed value exceeds the regulation and control range, the operation stability of the outdoor fan can be affected. Therefore, when the outdoor fan is matched with the rotating speed lower limit value and the new oil temperature superheat degree still does not meet the oil temperature condition, the air conditioner regulates the oil temperature superheat degree by increasing the rotating speed value of the indoor fan, so that the oil pool temperature and the high-pressure value are continuously increased by increasing the evaporation efficiency of the indoor heat exchanger, and finally, the effect of increasing the oil temperature superheat degree is achieved.

Optionally, referring to fig. 4, when the superheat degree of the oil temperature does not meet the oil temperature condition, the air conditioner regulates the rotation speed value of the outdoor fan and/or the indoor fan, including:

s31, the air conditioner reduces the rotating speed value of the outdoor fan at a first preset change rate under the condition that the overheat degree of the oil temperature does not meet the oil temperature condition.

S32, the air conditioner re-acquires the new oil temperature superheat degree, and increases the rotating speed value of the indoor fan at a second preset change rate under the condition that the new oil temperature superheat degree does not meet the oil temperature condition.

S33, under the condition that the indoor fan rotating speed value of the indoor fan is larger than the rotating speed upper limit value, the air conditioner operates for a third preset time period with the indoor fan rotating speed value and then pushes prompt information carrying with the oil temperature overheat fault so as to prompt the oil temperature overheat fault.

Therefore, the rotating speed value of the indoor fan has a certain regulation and control range, and if the rotating speed value exceeds the regulation and control range, the operation stability of the indoor fan can be affected. Therefore, the air conditioner can monitor the rotating speed value and the rotating speed upper limit value of the indoor fan while increasing the rotating speed of the indoor fan. If the rotating speed value of the indoor fan is larger than the rotating speed upper limit value, the fact that the oil temperature superheat degree cannot be effectively regulated in a mode of regulating and controlling the outdoor fan and the indoor fan is indicated. At the moment, after the indoor fan runs for a third preset time period according to the rotation speed value of the indoor fan, prompt information is pushed, so that a user can know that the air conditioner has an oil temperature overheat fault and timely carries out fault treatment.

As shown in fig. 5, an embodiment of the present disclosure further provides a control method for an air conditioner, including:

s41, the air conditioner obtains the oil temperature superheat degree of the compressor of the air conditioner in a refrigeration mode.

S42, regulating and controlling the rotating speed value of the outdoor fan and/or the indoor fan by the air conditioner under the condition that the overheat degree of the oil temperature does not meet the oil temperature condition.

S43, when the overheat degree of the oil temperature meets the oil temperature condition, the air conditioner maintains the rotating speed value of the outdoor fan.

By adopting the control method for the air conditioner, which is provided by the embodiment of the disclosure, when the air conditioner determines that the superheat degree of the oil temperature meets the oil temperature condition, the rotating speed value of the outdoor fan is kept unchanged. The numerical value of the oil temperature superheat degree is kept stable, so that the oil temperature superheat degree continuously meets the oil temperature condition, and the running reliability of the air conditioner in a refrigeration mode is improved.

In step S43, when the degree of superheat of the oil temperature satisfies the oil temperature condition, the air conditioner may be configured to reduce the outdoor fan alone and then to satisfy the oil temperature condition. At this time, the air conditioner is operated with the latest regulated and controlled rotation speed value of the outdoor fan.

Optionally, the oil temperature superheat degree does not satisfy the oil temperature condition, including:

the oil temperature superheat degree is smaller than or equal to the preset oil temperature superheat degree.

Therefore, the air conditioner can know whether the oil temperature superheat degree needs the intervention of the indoor fan and the outdoor fan according to the oil temperature superheat degree and the numerical value of the preset oil temperature superheat degree, and the accuracy of the regulation and control of the outdoor fan and/or the indoor fan is improved.

As shown in fig. 6, an embodiment of the present disclosure further provides a control method for an air conditioner, including:

s51, the air conditioner acquires an outdoor environment temperature value associated with the air conditioner.

S52, acquiring the oil temperature superheat degree of the compressor in a refrigeration mode under the condition that the outdoor environment temperature value is smaller than or equal to a preset temperature value.

In this step, the preset temperature value may be 15℃or 10 ℃.

S53, the air conditioner regulates and controls the rotation speed value of the outdoor fan and/or the indoor fan under the condition that the overheat degree of the oil temperature does not meet the oil temperature condition.

By adopting the control method for the air conditioner, the air conditioner can judge the running mode of the air conditioner according to the outdoor environment temperature value and the preset temperature value. And the air conditioner can only generate the condition of low oil temperature superheat degree when the outdoor environment temperature value is low. Therefore, when the outdoor environment temperature value is smaller than or equal to the preset temperature value, the air conditioner judges whether the oil temperature superheat degree meets the oil temperature condition or not. Therefore, the oil temperature superheat degree is not required to be continuously monitored, the oil temperature superheat degree is obtained only when the outdoor environment temperature value is low, and the accuracy of regulating and controlling the oil temperature superheat degree of the compressor is improved according to whether the oil temperature superheat degree meets the oil temperature condition or not.

In practical application, the control method for the air conditioner specifically performs the following steps:

and S61, continuously monitoring the outdoor environment temperature after the air conditioner operates in a refrigerating mode. After the outdoor environment temperature is less than 15 ℃, the air conditioner obtains the oil temperature superheat degree.

S62, judging that the superheat degree of the oil temperature is smaller than the preset superheat degree of the oil temperature. Thus, the air conditioner controls the outdoor fan to decrease the value of the outdoor fan rotation speed at a rotation speed change rate of 30 rpm. After 5 minutes, the air conditioner acquires the new oil temperature superheat degree again, and the new oil temperature superheat degree is still smaller than the preset oil temperature superheat degree after judging. The air conditioner controls the outdoor fan again to reduce the rotational speed value of the outdoor fan at a rotational speed change rate of 30 rpm. After the two times of regulation, the new rotation speed value of the outdoor fan is equal to the lower limit value of the rotation speed of the outdoor fan. However, the updated oil temperature superheat is still less than the preset oil temperature superheat.

S63, the air conditioner controls the indoor fan to increase the rotating speed value of the indoor fan at the rotating speed change rate of 20 revolutions per minute. The air conditioner again judges whether the latest oil temperature superheat degree is greater than the preset oil temperature superheat degree. And judging that the latest oil temperature superheat degree is larger than the preset oil temperature superheat degree. Therefore, the air conditioner realizes the regulation and control of the oil temperature superheat degree of the compressor by regulating and controlling the rotation speed value of the outdoor fan and the rotation speed value of the indoor fan in sequence, and improves the running reliability of the air conditioner in a refrigeration mode.

As shown in fig. 7, an embodiment of the present disclosure provides a control device for an air conditioner, including an acquisition module 201 and an execution module 202. The acquisition module 201 is configured to acquire an oil temperature superheat degree of a compressor of the air conditioner in a cooling mode; the execution module 202 is configured to regulate the rotational speed value of the outdoor fan and/or the indoor fan in the case where the oil temperature superheat degree does not satisfy the oil temperature condition.

By adopting the control device for the air conditioner, provided by the embodiment of the disclosure, the control of the oil temperature superheat degree of the compressor can be realized when the air conditioner operates in a refrigeration mode by regulating and controlling the rotation speed of the outdoor fan and/or the indoor fan, and the operation reliability of the air conditioner in the refrigeration mode is improved.
