[0002] When the air conditioner is in heating mode, if the outdoor ambient temperature is low, ice can easily form on the outdoor unit chassis after defrosting, making it difficult for water to drain from the outdoor unit chassis.

[0003] The usual solution to the above problem is to add an electric heating element to the outdoor unit chassis to melt the ice layer on the chassis, so that the defrost water can be discharged smoothly from the outdoor unit chassis.

[0004] In the existing technology, the activation control of the heating belt on the outdoor unit chassis is determined solely by the outdoor ambient temperature.

[0011] Optionally, when the air conditioner is in heating mode and the current outdoor ambient temperature is lower than a first temperature value, before determining whether the saturation temperature corresponding to the current suction pressure of the air conditioner is lower than a second temperature value, the control method further includes: upon receiving a start-up control command, detecting the air conditioner's operating mode; when the air conditioner's operating mode is not heating mode, not turning on the air conditioner's electric heating element; and when the air conditioner's operating mode is heating mode, determining whether the current outdoor ambient temperature is lower than the first temperature value within a continuous second preset time period.

[0012] Optionally, when the air conditioner is in the heating mode, after determining whether the current outdoor ambient temperature is lower than the first temperature value within a continuous second preset time period, the control method further includes: when the air conditioner is in the heating mode and the current outdoor ambient temperature is greater than or equal to the first temperature value within a continuous second preset time period, not turning on the electric heating belt.

[0013] Optionally, the control method further includes: after a third preset time period, sequentially executing the determining step, the acquiring step, and the executing step at least once, until the air conditioner is turned off.

[0014] According to another aspect of this application, a control device for an air conditioner is provided. The outdoor unit of the air conditioner includes an electric heating element and a heat exchanger. The control device includes: a first determining unit, configured to perform a determining step, determining whether the saturation temperature corresponding to the current suction pressure of the air conditioner is less than a second temperature value when the air conditioner is in heating mode and the current outdoor ambient temperature is less than a first temperature value; an acquiring unit, configured to perform an acquiring step, acquiring the temperature value of the temperature sensor of the heat exchanger when the saturation temperature corresponding to the suction pressure is less than the second temperature value, and turning on the electric heating element when the temperature value of the temperature sensor of the heat exchanger is less than a third temperature value; and a first executing unit, configured to perform an executing step, not turning on the electric heating element when the saturation temperature corresponding to the suction pressure is greater than or equal to the second temperature value.

In this solution, the actual operating effect of the air conditioner is determined by the saturation temperature corresponding to the suction pressure of the air conditioning system. If the saturation temperature corresponding to the suction pressure is greater than or equal to the second temperature value, the electric heating belt does not need to be turned on. If the saturation temperature corresponding to the suction pressure is less than the second temperature value, the outdoor unit chassis is checked for ice buildup by the temperature sensor at the bottom of the heat exchanger. That is, if the temperature value of the temperature sensor is less than the third temperature value, the electric heating belt is turned on. This ensures more precise and reasonable control of the electric heating belt, avoiding unnecessary activation and solving the problem of energy waste caused by unreasonable control of the electric heating belt on the outdoor unit chassis in existing technologies.

[0030] The methods and embodiments provided in this application can be executed on a mobile terminal, computer terminal, or similar computing device. Taking running on a mobile terminal as an example, Figure 1 This is a hardware structure block diagram of a mobile terminal for an air conditioner control method according to an embodiment of the present invention. Figure 1 As shown, a mobile terminal may include one or more ( Figure 1 Only one is shown in the diagram.

[0032] This embodiment provides a method for controlling an air conditioner that runs on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0033] Figure 2 This is a flowchart of an air conditioner control method according to an embodiment of this application. The outdoor unit of the air conditioner includes an electric heating element and a heat exchanger, such as... Figure 2 As shown, the control method includes the following steps:

[0034] Step S201, Determination Step: When the air conditioner is in heating mode and the current outdoor ambient temperature is less than the first temperature value, determine whether the saturation temperature corresponding to the current suction pressure of the air conditioner is less than the second temperature value.

[0035] In practical applications, the magnitude of the aforementioned first temperature value can be flexibly adjusted according to the specific application conditions. This application does not impose a limitation on the magnitude of the aforementioned first temperature value. Furthermore, the aforementioned first temperature value can be a preset ambient temperature threshold obtained from multiple experiments. In one specific embodiment of this application, the aforementioned first temperature value can be 3°C.

[0036] In addition, the air intake pressure of an air conditioner is the air intake pressure of the air conditioning system (air conditioning unit).

[0037] In step S201 above, when the air conditioner is in heating mode and the current outdoor ambient temperature is lower than the first temperature value, the saturation temperature corresponding to the current suction pressure of the air conditioner can be obtained after a ninth preset time period.

[0038] Step S202, the acquisition step, when the saturation temperature corresponding to the above-mentioned suction pressure is less than the above-mentioned second temperature value, the temperature value of the temperature sensing bulb of the heat exchanger is acquired, and when the temperature value of the temperature sensing bulb of the heat exchanger is less than the third temperature value, the electric heating belt is turned on.

[0039] In step S202 above, since the program requires a certain waiting time to run, if the temperature value of the heat exchanger's sensing bulb is lower than the third temperature value, the electric heating belt can be turned on after a fourth preset time period. Of course, this application does not limit the size of the fourth preset time period; it can be flexibly adjusted according to actual circumstances. The fourth preset time period can be set to a relatively small value, such as 3 to 5 seconds.

[0040] Specifically, the magnitudes of the second and third temperature values ​​can be flexibly adjusted according to actual application conditions. This application does not impose any limitations on the magnitudes of the second and third temperature values. Furthermore, the second temperature value can be the saturation temperature corresponding to a preset intake pressure obtained from multiple experiments. In one specific embodiment of this application, the second temperature value can be 5°C. The third temperature value can be the preset temperature value of the heat exchanger's sensing bulb obtained from multiple experiments. In one specific embodiment of this application, the third temperature value can be 0°C.

[0041] Step S203: Execute the following step: If the saturation temperature corresponding to the above-mentioned suction pressure is greater than or equal to the above-mentioned second temperature value, do not turn on the above-mentioned electric heating belt.

[0042] In step S203 above, since the program requires a certain waiting time to run, if the saturation temperature corresponding to the inhalation pressure is greater than or equal to the second temperature value, the electric heating belt may not be activated after a fifth preset time period. Of course, this application does not limit the size of the fifth preset time period; it can be flexibly adjusted according to actual circumstances. The fifth preset time period can be set to a relatively small value, such as 3 to 5 seconds.

[0043] In this embodiment, when the air conditioner is in heating mode and the current outdoor ambient temperature is lower than a first temperature value, it is determined whether the saturation temperature corresponding to the current suction pressure of the air conditioning system is lower than a second temperature value. If the saturation temperature corresponding to the current suction pressure of the air conditioning system is lower than the second temperature value, the temperature value of the heat exchanger's temperature sensor is obtained. Based on the relationship between the temperature value of the heat exchanger's temperature sensor and a third temperature value, it is determined whether to activate the electric heating belt. That is, if the temperature value of the heat exchanger's temperature sensor is lower than the third temperature value, the electric heating belt is activated; if the saturation temperature corresponding to the current suction pressure of the air conditioning system is greater than or equal to the second temperature value, the electric heating belt is not activated. In this solution, the actual operating effect of the air conditioner is determined by the saturation temperature corresponding to the suction pressure of the air conditioning system. If the saturation temperature corresponding to the suction pressure is greater than or equal to the second temperature value mentioned above, the electric heating belt will not be turned on. If the saturation temperature corresponding to the suction pressure is less than the second temperature value, the outdoor unit chassis is checked for ice buildup by the temperature sensor at the bottom of the heat exchanger. That is, if the temperature value of the temperature sensor is less than the third temperature value, the electric heating belt is turned on. This ensures more precise and reasonable control of the electric heating belt, avoiding unnecessary activation of the electric heating belt. This solves the problem of energy waste caused by unreasonable control of the activation of the electric heating belt on the outdoor unit chassis in the existing technology.

[0044] Furthermore, this application does not restrict the location of the temperature sensor in the heat exchanger of the outdoor unit of the air conditioner; the location of the temperature sensor can be reasonably arranged according to the actual situation of the air conditioner.

[0045] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0046] In specific implementation, the above control method can also, in step S204, prevent the electric heating belt from being turned on when the temperature value of the heat exchanger's temperature sensing bulb is greater than or equal to the third temperature value. In this solution, the electric heating belt is not turned on when the temperature value of the heat exchanger's temperature sensing bulb is greater than or equal to the third temperature value, thus further achieving precise control over whether the electric heating belt is turned on and ensuring that the control of the electric heating belt is more reasonable.

[0047] In practical applications, since the program requires a certain waiting time to run, the electric heating element will not be activated after the sixth preset time period if the temperature value of the heat exchanger's sensing bulb is greater than or equal to the third temperature value. Of course, this application does not limit the length of the sixth preset time period; it can be flexibly adjusted according to actual conditions. The sixth preset time period can be set to a relatively small value, such as 3 to 5 seconds.

[0048] In order to obtain the temperature value of the heat exchanger's temperature sensor more accurately, and to further ensure that the electric heating belt is controlled more accurately based on the temperature value of the heat exchanger's temperature sensor, the above-mentioned step S202 of this application can be achieved by the following steps: when the saturation temperature corresponding to the above-mentioned suction pressure is less than the above-mentioned second temperature value, after a first preset time period, the temperature value of the heat exchanger's temperature sensor is obtained.

[0049] In practical applications, the size of the first preset time period can be flexibly adjusted according to the actual situation. In this application, the size of the first preset time period is not limited.

[0050] In some embodiments, step S201 can be implemented through the following steps: when the air conditioner is operating in heating mode and the current outdoor ambient temperature is lower than the first temperature value for a continuous second preset time period, determine whether the saturation temperature corresponding to the current suction pressure of the air conditioner is lower than the second temperature value. In this solution, when the air conditioner is operating in heating mode and the outdoor ambient temperature is lower than the first temperature value for a continuous second preset time period, it indicates that the outdoor ambient temperature is low. Therefore, a preliminary judgment is made based on the outdoor ambient temperature to avoid turning on the electric heating element when the outdoor ambient temperature is high. This further ensures more reasonable control of the electric heating element and further reduces the unnecessary activation of the electric heating element.

[0051] In practical applications, the size of the second preset time period can be flexibly adjusted according to the actual situation. In this application, the size of the second preset time period is not limited.

[0052] In some specific embodiments, the control method may further include steps S205, S206, and S207. Specifically, in step S205, before determining whether the saturation temperature corresponding to the current suction pressure of the air conditioner is lower than a second temperature value when the air conditioner is in heating mode and the current outdoor ambient temperature is lower than a first temperature value, the air conditioner's operating mode is detected after receiving the start-up control command; in step S206, the electric heating element of the air conditioner is not activated when the air conditioner is not in heating mode; in step S207, when the air conditioner is in heating mode, it is determined whether the current outdoor ambient temperature is lower than the first temperature value within a continuous second preset time period. In this embodiment, a preliminary judgment is made based on the air conditioner's operating mode, which avoids activating the electric heating element when the air conditioner is not in heating mode, further preventing resource waste.

[0053] Specifically, after receiving the start-up control command, the air conditioner can detect its operating mode after a seventh preset time period. Additionally, if the air conditioner is not in heating mode, the electric heating element can be deactivated after an eighth preset time period.

[0054] In some embodiments, the control method may further include step S208, where, when the air conditioner is in the heating mode, after determining whether the current outdoor ambient temperature is lower than the first temperature value within the continuous second preset time period, the electric heating belt is not turned on when the air conditioner is in the heating mode and the current outdoor ambient temperature is greater than or equal to the first temperature value within the continuous second preset time period, thus further avoiding the problem of wasting resources.

[0055] Specifically, when the air conditioner is operating in the heating mode described above, and the current outdoor ambient temperature is greater than or equal to the first temperature value during the second preset time period, the electric heating belt may not be turned on after the eighth preset time period.

[0056] In some specific implementation processes, the above control method may further include step S209, where, after a third preset time period, the above determining step, the above acquiring step, and the above executing step are executed at least once in sequence until the air conditioner is turned off. This further ensures reasonable control of the electric heating element through continuous detection and avoids energy waste.

[0057] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the air conditioner control method of this application will be described in detail below with reference to specific embodiments.

[0058] This embodiment relates to a specific air conditioner control method, such as... Figure 3 As shown, it includes the following steps:

[0059] Step S1: The air conditioner is powered on. After receiving the start-up control command and after a seventh preset time period, the air conditioner obtains its operating mode.

[0060] Step S2: If the air conditioner is not in heating mode, the electric heating element of the air conditioner will not be turned on after the eighth preset time period.

[0061] Step S3: If the air conditioner is in heating mode, determine whether the current outdoor ambient temperature is lower than the first temperature value within a continuous second preset time period.

[0062] Step S4: If the outdoor ambient temperature is greater than or equal to the first temperature value during a continuous second preset time period, the electric heating belt will not be turned on after an eighth preset time period; if the outdoor ambient temperature is less than the first temperature value during a continuous second preset time period, the saturation temperature corresponding to the current air intake pressure of the air conditioner will be obtained after a ninth preset time period, and it will be determined whether the saturation temperature corresponding to the current air intake pressure of the air conditioner is less than the second temperature value.

[0063] Step S5: If the saturation temperature corresponding to the suction pressure is greater than or equal to the second temperature value, the electric heating belt is not turned on after the fifth preset time period; if the saturation temperature corresponding to the suction pressure is less than the second temperature value, the temperature value of the heat exchanger's temperature sensor is obtained after the first preset time period, and it is determined whether the temperature value of the air conditioner's heat exchanger's temperature sensor is less than the third temperature value.

[0064] Step S6: If the temperature value of the heat exchanger's sensing bulb is less than the third temperature value, the electric heating belt can be turned on after a fourth preset time period; if the temperature value of the heat exchanger's sensing bulb is greater than or equal to the third temperature value, the electric heating belt will not be turned on after a sixth preset time period.

[0065] Step S7: After the third preset time period, execute steps S1 to S5 above at least once in sequence until the air conditioner is turned off.

[0066] The air conditioner control method of this application can effectively avoid the situation where the electric heating belt is turned on due to misjudgment of the air conditioner's operating mode, such as when the air conditioner is not in heating mode. At the same time, it can also reduce unnecessary energy waste caused by the electric heating belt being turned on by mistake, based on the actual operating conditions of the air conditioner.

[0067] This application also provides an air conditioner control device. It should be noted that the air conditioner control device of this application embodiment can be used to execute the air conditioner control method provided in this application embodiment. This device is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0068] The control device for an air conditioner provided in the embodiments of this application will be described below.

[0069] Figure 4 This is a schematic diagram of the control device for an air conditioner according to an embodiment of this application. The outdoor unit of the air conditioner includes an electric heating element and a heat exchanger, such as... Figure 4 As shown, the control device includes:

[0070] The first determining unit 10 is used to perform the determining step, which determines whether the saturation temperature corresponding to the current suction pressure of the air conditioner is less than the second temperature value when the air conditioner is in heating mode and the current outdoor ambient temperature is less than the first temperature value.

[0071] In practical applications, the magnitude of the aforementioned first temperature value can be flexibly adjusted according to the specific application conditions. This application does not impose a limitation on the magnitude of the aforementioned first temperature value. Furthermore, the aforementioned first temperature value can be a preset ambient temperature threshold obtained from multiple experiments. In one specific embodiment of this application, the aforementioned first temperature value can be 3°C.

[0072] In addition, the air intake pressure of an air conditioner is the air intake pressure of the air conditioning system (air conditioning unit).

[0073] When the air conditioner is in heating mode and the current outdoor ambient temperature is lower than the first temperature value, the saturation temperature corresponding to the current air intake pressure of the air conditioner can be obtained after the ninth preset time period.

[0074] The acquisition unit 20 is used to perform the acquisition step, which is to acquire the temperature value of the temperature sensing bulb of the heat exchanger when the saturation temperature corresponding to the above-mentioned suction pressure is less than the above-mentioned second temperature value, and to turn on the above-mentioned electric heating belt when the temperature value of the temperature sensing bulb of the heat exchanger is less than the third temperature value.

[0075] Since the program requires a certain waiting time to run, the electric heating element can be activated after a fourth preset time period if the temperature value of the heat exchanger's sensing bulb is lower than the third temperature value. Of course, this application does not limit the length of the fourth preset time period; it can be flexibly adjusted according to actual conditions. The fourth preset time period can be set to a relatively small value, such as 3 to 5 seconds.

[0076] Specifically, the magnitudes of the second and third temperature values ​​can be flexibly adjusted according to actual application conditions. In this application, there is no limitation on the magnitudes of the first and third temperature values. Furthermore, the second temperature value can be the saturation temperature corresponding to a preset intake pressure obtained from multiple experiments. In one specific embodiment of this application, the second temperature value can be 5°C. The third temperature value can be the preset temperature value of the heat exchanger's sensing bulb obtained from multiple experiments. In one specific embodiment of this application, the third temperature value can be 0°C.

[0077] The first execution unit 30 is used to perform the execution steps, and when the saturation temperature corresponding to the above-mentioned suction pressure is greater than or equal to the above-mentioned second temperature value, the above-mentioned electric heating belt is not turned on.

[0078] Since the program requires a certain waiting time to run, if the saturation temperature corresponding to the intake pressure is greater than or equal to the second temperature value mentioned above, the electric heating belt may not be activated after a fifth preset time period. Of course, this application does not limit the size of the fifth preset time period; it can be flexibly adjusted according to actual circumstances. The fifth preset time period can be set to a relatively small value, such as 3 to 5 seconds.

[0079] In this embodiment, the first determining unit is used to determine whether the saturation temperature corresponding to the current suction pressure of the air conditioning system is less than a second temperature value when the air conditioner is in heating mode and the current outdoor ambient temperature is less than a first temperature value; the acquiring unit is used to acquire the temperature value of the heat exchanger's temperature sensor when the saturation temperature corresponding to the current suction pressure of the air conditioning system is less than the second temperature value, and determine whether to turn on the electric heating belt based on the relationship between the temperature value of the heat exchanger's temperature sensor and a third temperature value, that is, to turn on the electric heating belt when the temperature value of the heat exchanger's temperature sensor is less than the third temperature value; the first executing unit is used not to turn on the electric heating belt when the saturation temperature corresponding to the current suction pressure of the air conditioning system is greater than or equal to the second temperature value. In this solution, the actual operating effect of the air conditioner is determined by the saturation temperature corresponding to the suction pressure of the air conditioning system. If the saturation temperature corresponding to the suction pressure is greater than or equal to the second temperature value mentioned above, the electric heating belt will not be turned on. If the saturation temperature corresponding to the suction pressure is less than the second temperature value, the outdoor unit chassis is checked for ice buildup by the temperature sensor at the bottom of the heat exchanger. That is, if the temperature value of the temperature sensor is less than the third temperature value, the electric heating belt is turned on. This ensures more precise and reasonable control of the electric heating belt, avoiding unnecessary activation of the electric heating belt. This solves the problem of energy waste caused by unreasonable control of the activation of the electric heating belt on the outdoor unit chassis in the existing technology.

[0080] Furthermore, this application does not restrict the location of the temperature sensor in the heat exchanger of the outdoor unit of the air conditioner; the location of the temperature sensor can be reasonably arranged according to the actual situation of the air conditioner.

[0081] In specific implementation, the aforementioned control device can also have a second execution unit to prevent the electric heating belt from activating when the temperature value of the heat exchanger's sensing bulb is greater than or equal to the third temperature value. In this solution, the electric heating belt is not activated when the temperature value of the heat exchanger's sensing bulb is greater than or equal to the third temperature value, thus further achieving precise control over whether the electric heating belt is activated and ensuring more reasonable control of the electric heating belt.

[0082] In practical applications, since the program requires a certain waiting time to run, the electric heating element will not be activated after the sixth preset time period if the temperature value of the heat exchanger's sensing bulb is greater than or equal to the third temperature value. Of course, this application does not limit the length of the sixth preset time period; it can be flexibly adjusted according to actual conditions. The sixth preset time period can be set to a relatively small value, such as 3 to 5 seconds.

[0084] In practical applications, the size of the first preset time period can be flexibly adjusted according to the actual situation. In this application, the size of the first preset time period is not limited.

[0085] In some embodiments, the first determining unit includes a first determining module, used to determine whether the saturation temperature corresponding to the current suction pressure of the air conditioner is less than the second temperature value when the air conditioner is operating in the heating mode and the current outdoor ambient temperature is less than the first temperature value for a continuous second preset time period. In this solution, when the air conditioner is operating in the heating mode and the outdoor ambient temperature is less than the first temperature value for a continuous second preset time period, it indicates that the outdoor ambient temperature is low. This allows for a preliminary judgment based on the outdoor ambient temperature, avoiding the activation of the electric heating element when the outdoor ambient temperature is high. This further ensures more reasonable control of the electric heating element and further reduces the unnecessary activation of the electric heating element.

[0086] In practical applications, the size of the second preset time period can be flexibly adjusted according to the actual situation. In this application, the size of the second preset time period is not limited.

[0087] In some specific embodiments, the control device may further include a receiving unit, a third execution unit, and a second determining unit.

The third execution unit is used to prevent the air conditioner's electric heating element from activating when the air conditioner's operating mode is not heating mode. The second determining unit is used to determine whether the current outdoor ambient temperature is lower than the first temperature value within a continuous second preset time period when the air conditioner's operating mode is heating mode. In this embodiment, a preliminary judgment is made based on the air conditioner's operating mode, thus avoiding the activation of the electric heating element when the air conditioner is not in heating mode, further preventing resource waste.
