Description

Air conditioner control method, machine-readable storage medium, and air conditioner

Technical Field

The present invention relates to the technical field of air treatment equipment, and in particular to a control method of an air conditioner, a machine-readable storage medium and an air conditioner.

Background technique

At present, air conditioners usually have a dehumidification function, especially in scenarios with high humidity, the dehumidification function of the air conditioner is often used. However, when dehumidifying in a high temperature environment and a high set temperature, the indoor fan runs at the lowest speed to dehumidify by lowering the coil temperature. This causes the air flow in the entire room to deteriorate, and the indoor temperature and humidity cannot be uniform; in order to prevent the temperature from shutting down, the compressor runs at a low frequency, and the coil has a small cooling amount, resulting in a general dehumidification effect. When dehumidifying in scenarios with low indoor temperature and high humidity such as the return of the south wind, the dew point temperature is very low. In order to avoid the indoor temperature being too low, electric heating is usually used; however, the heat from the electric heating is not enough to make up for the cooling brought by the refrigeration, resulting in a poor user experience.

In summary, when the existing air conditioner is in dehumidification operation under special usage scenarios, it cannot well balance the dehumidification effect and the user's comfortable temperature experience, which reduces the user's comprehensive usage experience.

FIG1 is a schematic flow chart of a control method of an air conditioner according to an embodiment of the present invention, and in combination with FIG2-6, the present invention provides a control method of an air conditioner 100. As shown in FIG10, the air conditioner includes two laterally arranged air outlets 140, and the air outlet 140 includes an air duct 141, an indoor heat exchanger 143 and a fan 142.

The control method of the air conditioner 100 may include the following steps:

S100, in response to a dehumidification mode start instruction, obtaining a set temperature;

S200, executing a corresponding dehumidification strategy at least according to the temperature of the set temperature to control one or both of the two air outlet parts 140 to operate in cooling mode.

Specifically, the two air outlets 140 are independent of each other, and the air duct 141 of each air outlet 140 is connected to an air outlet, so that the air conditioner can achieve the following air outlet modes: ① Both air outlets 140 discharge cold air, specifically, the two air outlets 140 are in cooling operation at the same time, that is, the indoor heat exchangers 143 of the two air outlets 140 are in cooling operation, and the fans 142 in the two air outlets 140 are turned on; ② One air outlet 140 discharges hot air and the other air outlet 140 does not discharge air, specifically, one air outlet 140 is in cooling operation and the other air outlet 140 is in cooling operation. 0 is not working, that is, the indoor heat exchanger 143 in one air outlet 140 is in cooling operation and the fan 142 is turned on, and the indoor heat exchanger 143 and the fan 142 in the other air outlet 140 are both turned off; ③ One air outlet 140 discharges cold air and the other air outlet 140 discharges non-heat exchange air. Specifically, one air outlet 140 is in cooling operation and the other air outlet 140 is in non-heat exchange operation, that is, the indoor heat exchanger 143 in one air outlet 140 is in cooling operation and the fan 142 is turned on, and the indoor heat exchanger 143 in the other air outlet 140 is turned off and the fan 142 is turned on. Among them, the non-heat exchange air can be natural wind or fresh air. Multiple temperature ranges and multiple dehumidification strategies can be preset in the air conditioner, and each temperature range corresponds to a dehumidification strategy.

In this embodiment, when a dehumidification mode start instruction is received, a set temperature is obtained, and then a corresponding dehumidification strategy is executed at least according to the set temperature. That is, during dehumidification, one or both of the two air outlets 140 are controlled to operate for cooling according to the set temperature, so as to control the cooling capacity and dehumidification capacity according to the working conditions. In addition, since the cooling capacity affects both the dehumidification effect and the user's temperature experience. Therefore, the control method of the present invention can enable the air conditioner to well balance the dehumidification effect and the user's temperature experience in different dehumidification scenarios, so that the user has a better comprehensive use experience.

As shown in FIG. 2 , in some optional embodiments of the present invention, S200, the step of executing a corresponding dehumidification strategy at least according to a set temperature may include the following steps:

S210, in response to the set temperature being less than the first preset temperature, executing a first dehumidification strategy; the first dehumidification strategy includes: controlling one of the two air outlets 140 to operate in cooling mode and the other to not operate or operate in non-heat exchange mode.

In some optional embodiments of the present invention, S200, the execution of a corresponding dehumidification strategy at least according to a set temperature may include the following steps:

S220, in response to the set temperature being greater than or equal to the second preset temperature, executing a second dehumidification strategy; the second dehumidification strategy includes: obtaining the indoor temperature and indoor humidity, and controlling the cooling operation of one or both of the two indoor heat exchangers 143 at least according to the indoor temperature and indoor humidity.

As shown in FIG. 2 , in some optional embodiments of the present invention, S200, the step of executing a corresponding dehumidification strategy at least according to a set temperature may include the following steps:

S210, in response to the set temperature being less than the first preset temperature, executing a first dehumidification strategy; the first dehumidification strategy includes: controlling one of the two air outlets 140 to operate in cooling mode and the other to not operate or operate in non-heat exchange mode;

S220, in response to the set temperature being greater than or equal to the second preset temperature, executing a second dehumidification strategy; the second dehumidification strategy includes: obtaining the indoor temperature and the indoor humidity, and controlling one or both of the two indoor heat exchangers 143 to operate in cooling mode at least according to the indoor temperature and the indoor humidity;

Wherein, the first preset temperature is lower than the second preset temperature.

In the above three embodiments, the first preset temperature may be 15-21° C., for example, the first preset temperature may be any one of 15° C., 16° C., 17° C., 18° C., 19° C., 20° C. and 21° C. Preferably, the first preset temperature is 20° C.

The second preset temperature may be 24-28° C., for example, the second preset temperature may be any one of 24° C., 25° C., 26° C., 27° C. and 28° C. Preferably, the second preset temperature is 25° C.

In step S210, when the set temperature is less than the first preset temperature, the temperature in the indoor space where the air conditioner is located is relatively low, for example, the current time is in the season of the return of the south wind. When dehumidification is performed at low temperature, the indoor temperature is low, the dew point temperature is very low, and a lower coil temperature is required for dehumidification. Under the same other conditions, compared with the refrigeration of the double air outlet 140, the refrigeration of the single air outlet 140 has a lower cooling capacity, which can prevent excessive cooling, so that the user can have a better temperature experience. In addition, compared with the refrigeration operation of the double air outlet 140, the refrigeration operation of the single air outlet 140 can reduce the total heat exchange area of the indoor heat exchanger 143 by half, so that the indoor coil temperature can be significantly reduced, and the dehumidification amount can be greatly increased. Therefore, when the set temperature is less than the first preset temperature, the first dehumidification strategy is executed, which can prevent the indoor temperature from dropping too low and have a lot of dehumidification; that is, it can take into account both the dehumidification effect and the user's temperature experience, so that the user has a good comprehensive use experience.

In step S220, when the set temperature is greater than or equal to the second preset temperature, it means that the set temperature is high and the indoor temperature is easy to reach the set temperature. A high set temperature means that the user does not like low temperatures. At this time, one or both of the two indoor heat exchangers 143 are controlled to operate in cooling mode according to the indoor temperature and indoor humidity to balance the temperature demand and humidity demand, so that the user has a good humidity experience and temperature experience.

Furthermore, in some optional embodiments of the present invention, an electric heater 144 is provided in each air duct 141. The first dehumidification strategy also includes: at least controlling the indoor heat exchanger corresponding to the air outlet 140 in cooling operation to be turned on. "At least controlling the indoor heat exchanger corresponding to the air outlet 140 in cooling operation to be turned on" includes the following two situations: ① controlling the indoor heat exchanger corresponding to the air outlet 140 in cooling operation to be turned on; ② controlling the electric heaters 144 of both air outlets 140 to be turned on.

In this embodiment, when the set temperature is lower than the first preset temperature, turning on the electric heating can make the heating capacity of the electric heating greater than or equal to the cooling capacity of the indoor heat exchanger 143, thereby achieving constant temperature dehumidification in the room, which can further enhance the user's comprehensive usage experience.

Furthermore, compared with the method of turning on only one electric heater, turning on two electric heaters at the same time is more conducive to achieving constant temperature dehumidification in the room, thereby being more conducive to improving the user's comprehensive usage experience.

As shown in FIG. 3 , in some optional embodiments of the present invention, in the first dehumidification strategy, the step of controlling one of the two air outlets 140 to operate in cooling mode and the other to not operate or operate in non-heat exchange mode includes the following steps:

S211, obtaining the indoor user location;

S212, controlling the air outlet 140 far from the user position to operate in cooling mode, and controlling the other air outlet 140 to operate in non-operation or non-heat exchange mode.

When the air conditioner is performing low-temperature dehumidification, the air outlet 140 for cooling operation is selected according to the user's position, and the air outlet 140 far away from the user's position is used as a cooling air outlet column. While ensuring the dehumidification effect, it is more conducive to improving the user's temperature experience, and further more conducive to improving the user's comprehensive usage experience.

Preferably, S212 includes: controlling the air outlet 140 far from the user position to operate in cooling mode, and controlling the other air outlet 140 to operate in non-heat exchange mode. Compared with the mode in which the other air outlet 140 is not working, the other air outlet 140 discharges non-heat exchange air, which can improve the fluidity of indoor air, thereby being more conducive to the uniformity of indoor temperature and humidity, and further more conducive to rapid dehumidification.

Further preferably, S212 includes: controlling the air outlet 140 far from the user position to operate in cooling mode, and controlling another air outlet 140 to operate in non-heat exchange mode and at a high wind speed. For example, the air outlet 140 in non-heat exchange mode may rotate at a maximum preset speed.

As shown in FIG. 4 , in some optional embodiments of the present invention, in the second dehumidification strategy, controlling one or both of the two air outlets 140 to operate in cooling mode at least according to the indoor temperature and the indoor humidity may include the following steps:

S221, determining whether the temperature difference between the indoor temperature and the set temperature is less than a preset temperature difference value, and whether the humidity difference between the indoor humidity and the set humidity is greater than a preset humidity difference value; if so, executing S222; if not, executing S223;

S222, controlling one air outlet portion 140 to operate in cooling mode;

S223, controlling the two air outlet parts 140 to operate in cooling mode.

Specifically, the preset humidity difference may be 5% to 20%, for example, 5%, 10%, 15%, 18% or 20%; preferably, the preset humidity difference is 10%.

In this embodiment, when the set temperature is greater than or equal to the second preset temperature, if the temperature difference between the indoor temperature and the set temperature is less than the preset temperature difference value, and the humidity difference between the indoor humidity and the set humidity is greater than the preset humidity difference value, one air outlet 140 is controlled to operate for cooling, so that the air conditioner has a smaller cooling capacity, thereby preventing shutdown or very low-frequency operation caused by too fast temperature drop. In addition, compared with the cooling operation of the double air outlets 140, the cooling operation of the single air outlet 140 can reduce the total area of the indoor heat exchanger 143 by half, and can significantly reduce the coil temperature, so that the dehumidification capacity can be greatly improved.

When the set temperature is greater than or equal to the second preset temperature, if the temperature difference between the indoor temperature and the set temperature is not less than the preset temperature difference value, or the humidity difference between the indoor humidity and the set humidity is not greater than the preset humidity difference value, the user's demand for temperature is higher than the demand for humidity. At this time, controlling both air outlets 140 to operate in cooling mode is more conducive to quickly lowering the indoor ambient temperature, thereby allowing users to have a better overall use experience.

As shown in FIG. 5 , further, in some optional embodiments of the present invention, S222, controlling one air outlet portion 140 to operate in cooling mode, may include the following steps:

S2221, obtaining the indoor user location;

S2222, controlling the air outlet portion 140 far from the user position to operate in cooling mode, and controlling the other air outlet portion 140 to operate in non-operating mode or in non-heat exchanging mode.

In this embodiment, the air outlet 140 for cooling operation is selected according to the user's position, and the air outlet 140 far away from the user's position is used as a cooling air outlet column. While ensuring the dehumidification effect, it is more conducive to improving the user's temperature experience, and further more conducive to improving the user's overall usage experience.

Preferably, S2222 includes: controlling the air outlet 140 far from the user position to operate in cooling mode, and controlling the other air outlet 140 to operate in non-heat exchange mode. Compared with the mode in which the other air outlet 140 is not working, the other air outlet 140 discharges non-heat exchange air, which can improve the fluidity of indoor air, thereby being more conducive to the uniformity of indoor temperature and humidity, and further more conducive to rapid dehumidification.

Further preferably, S2222 includes: controlling the air outlet 140 far from the user position to operate in cooling mode, and controlling another air outlet 140 to operate in non-heat exchange mode and at a high wind speed. For example, the air outlet 140 in non-heat exchange mode may rotate at a maximum preset speed.

As shown in FIG. 2 , in some optional embodiments of the present invention, S200, the step of executing a corresponding dehumidification strategy at least according to a set temperature may include the following steps:

S230, in response to the set temperature being greater than or equal to the first preset temperature and less than the second preset temperature, executing a third dehumidification strategy; the third dehumidification strategy includes: controlling both air outlets 140 to operate in cooling mode.

Specifically, when the first preset temperature ≤ the set temperature < the second preset temperature, the two air outlets 140 are controlled to operate in cooling mode, so that the air conditioner has a larger dehumidification and cooling capacity, thereby providing users with a better overall usage experience.

In some optional embodiments of the present invention, the control of the air outlet 140 far from the user position to operate in cooling mode and the control of the other air outlet 140 not to operate or operate in non-heat exchange mode includes: controlling the air outlet 140 far from the user position to operate in cooling mode and to discharge air toward a side far from the user position. The above method can further enhance the user experience.

In some optional embodiments of the present invention, the control of the air outlet 140 far from the user's position to operate in cooling mode and the control of another air outlet 140 not to operate or operate in non-heat exchange mode includes: controlling the air outlet 140 near the user's position to operate in non-heat exchange mode and to execute the automatic swing mode. Through the above method, the fluidity of indoor air can be improved, which is conducive to improving the uniformity of indoor temperature and indoor humidity.

As shown in Figure 9, in some optional embodiments of the present invention, the air conditioner also includes a flow control device 115, which is configured to control two indoor heat exchangers 143 to work simultaneously or only one of the indoor heat exchangers 143 to work. When any air outlet 140 does not discharge air, the corresponding indoor heat exchanger 143 also does not work.

Specifically, the two air outlets 140 are respectively the first air outlet and the second air outlet, and the corresponding two indoor heat exchangers 143 are respectively the first indoor heat exchanger and the second indoor heat exchanger. The first indoor heat exchanger and the second indoor heat exchanger are arranged in parallel. In some embodiments, as shown in FIG9 , the flow control device 115 includes a three-way valve, the three-way valve has three openings, and the three openings are respectively connected to the outlet of the throttling device 114, the inlet of the first indoor heat exchanger, and the inlet of the second indoor heat exchanger. By controlling the three-way valve, it is possible to control only one heat exchanger to work or two heat exchangers to work simultaneously.

In some alternative embodiments, the flow control device includes two ball valves, the two ball valves are respectively a first ball valve and a second ball valve, and the two are arranged in parallel. The first ball valve is connected in series with the first indoor heat exchanger 143, and the second ball valve is connected in series with the second indoor heat exchanger 143. By controlling the first ball valve and the second ball valve, one indoor heat exchanger 143 can be controlled to work or two indoor heat exchangers 143 can work simultaneously.

In some embodiments of the present invention, as shown in FIG9 , the air conditioner 100 further includes a compressor 111, a four-way valve 112, an outdoor heat exchanger 113 and a throttling device 114. The throttling device 114 is located upstream of the indoor heat exchanger 143. The throttling device 114 is used to control the amount of the working medium entering the indoor heat exchanger 143. The throttling device 114 generally includes a capillary tube, a mechanical expansion valve, an electronic expansion valve, etc. Preferably, the throttling device 114 is an electronic expansion valve. The inlet of the throttling device 114 is connected to the outlet of the outdoor heat exchanger 113.

In some optional embodiments of the present invention, the air outlet 140 has a vertical bar-shaped air outlet. The air outlet is columnar, and the indoor unit of the air conditioner is a vertical air conditioner indoor unit. Preferably, the two air outlets are two air outlet columns, and the indoor unit is a double-column air conditioner indoor unit.

As shown in FIG. 6 , in a preferred embodiment of the present invention, the control method of the air conditioner 100 includes the following steps:

S10, in response to the dehumidification mode start instruction, obtain the set temperature; when the set temperature is ≥25°C, execute S20; when 25°C＞set temperature≥20°C, execute S30; when the set temperature is <20°C, execute S40;
