Background

Currently, an air conditioner generally has a dehumidifying function, and particularly in a use scene with high humidity, the dehumidifying function of the air conditioner is often used. However, when the indoor fan is dehumidified in a high-temperature environment and in a use scene with a higher set temperature, the indoor fan operates at the lowest speed so as to dehumidify by reducing the temperature of the coil. This results in poor air flowability of the whole room, and the indoor temperature and humidity cannot be uniform; in order to prevent Wen Tingji from running at low frequency, the temperature reduction of the coil is small, which leads to a general dehumidification effect. When dehumidification is performed in use scenes of low indoor temperature, high humidity, and the like, such as the back-to-the-sun, the dew point temperature is very low, and electric heating is usually adopted to avoid the low indoor temperature; however, the heat of electric heating is insufficient to compensate the cold energy caused by refrigeration, so that the use experience of users is poor.

Fig. 1 is a schematic flowchart of a control method of an air conditioner according to an embodiment of the present invention, and in conjunction with fig. 2-6, the present invention provides a control method of an air conditioner 100. As shown in fig. 10, the air conditioner includes two air outlet parts 140 arranged in a lateral direction, and the air outlet parts 140 include an air duct 141, an indoor heat exchanger 143, and a blower fan 142.

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

S100, responding to a dehumidification mode starting instruction, and acquiring a set temperature;

and S200, executing a corresponding dehumidification strategy at least according to the temperature of the set temperature so as to control one or two refrigeration operations in the two air outlet parts 140.

Specifically, the two air outlet portions 140 are independent from each other, and the air duct 141 of each air outlet portion 140 is connected with an air outlet, so that the air conditioner can realize the following air outlet modes: ① The two air outlet portions 140 both outlet cold air, specifically, the two air outlet portions 140 perform refrigeration operation simultaneously, that is, the indoor heat exchangers 143 of the two air outlet portions 140 perform refrigeration operation, and the fans 142 in the two air outlet portions 140 are all turned on; ② One air outlet portion 140 is used for exchanging hot air, the other air outlet portion 140 is not used for air outlet, specifically, one air outlet portion 140 is used for refrigerating operation, the other air outlet portion 140 is not used, namely, the indoor heat exchanger 143 in the one air outlet portion 140 is used for refrigerating operation, the fan 142 is started, and the indoor heat exchanger 143 and the fan 142 in the other air outlet portion 140 are both closed; ③ One air outlet portion 140 outputs cold air and the other air outlet portion 140 outputs non-heat exchanging air, specifically, one air outlet portion 140 performs refrigeration operation and the other air outlet portion 140 performs non-heat exchanging operation, namely, the indoor heat exchanger 143 in the one air outlet portion 140 performs refrigeration operation and the fan 142 is turned on, and the indoor heat exchanger 143 in the other air outlet portion 140 is turned off and the fan 142 is turned on. Wherein, the non-exchanging air can be natural air or fresh air. A plurality of temperature intervals and a plurality of dehumidification strategies can be preset in the air conditioner, and each temperature interval corresponds to one 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, at the time of dehumidification, one or both cooling operations of the two air outlet parts 140 are controlled according to the set temperature to achieve control of the cooling capacity and the dehumidification capacity according to the working conditions. In addition, the dehumidification effect and the user temperature experience are simultaneously affected due to the refrigerating capacity. Therefore, by adopting the control method, the air conditioner can well give consideration to dehumidification effect and user temperature experience under different dehumidification scenes, so that a user has better comprehensive use experience.

As shown in fig. 2, in some alternative embodiments of the present invention, S200, the performing the corresponding dehumidification strategy according to at least the set temperature may include the following steps:

S210, executing a first dehumidification strategy in response to the set temperature being less than a first preset temperature; the first dehumidification strategy includes: one of the two air outlet portions 140 is controlled to perform a cooling operation and the other one is controlled to perform a non-operation or a non-heat exchange operation.

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

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

As shown in fig. 2, in some alternative embodiments of the present invention, S200, the performing the corresponding dehumidification strategy according to at least the set temperature may include the following steps:

s210, executing a first dehumidification strategy in response to the set temperature being less than a first preset temperature; the first dehumidification strategy includes: one of the two air outlet parts 140 is controlled to perform refrigeration operation, and the other air outlet part is controlled to perform non-operation or non-heat exchange operation;

S220, executing a second dehumidification strategy in response to the set temperature being greater than or equal to a second preset temperature; the second dehumidification strategy includes: acquiring an indoor temperature and an indoor humidity, and controlling one or two refrigeration operations of the two indoor heat exchangers 143 at least according to the indoor temperature and the indoor humidity;

wherein the first preset temperature is less than the second preset temperature.

In the above three embodiments, the first preset temperature may be 15 to 21 ℃, for example: the first preset temperature may be any one of a temperature value of 15 ℃, 16 ℃, 17 ℃, 18 ℃, 19 ℃, 20 ℃ and 21 ℃. Preferably, the first preset temperature is 20 ℃.

The second preset temperature may be 24 to 28 ℃, for example: the second preset temperature may be any one of a temperature value of 24 ℃,25 ℃, 26 ℃, 27 ℃ and 28 ℃. Preferably, the second preset temperature is 25 ℃.

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 low, for example, the current time is in the southward season. When dehumidification is carried out at low temperature, the indoor temperature is low, the dew point temperature is low, dehumidification is carried out at lower coil temperature, and under the condition that other conditions are the same, compared with the refrigeration of the double air outlet parts 140, the refrigeration of the single air outlet part 140 has lower refrigeration capacity, excessive cooling can be prevented, and therefore a user can have better temperature experience. In addition, compared with the cooling operation of the double air outlet parts 140, the cooling operation of the single air outlet part 140 can reduce the total heat exchange area of the indoor heat exchanger 143 by half, so that the temperature of the indoor coil pipe can be obviously reduced, and the dehumidification amount can be greatly improved. Therefore, when the set temperature is smaller than the first preset temperature, the first dehumidification strategy is executed, so that the indoor temperature is prevented from being reduced too low, and a large amount of dehumidification is realized; that is, the dehumidification effect and the user temperature experience can be simultaneously considered, so that the user has good comprehensive use experience.

In step S220, when the set temperature is greater than or equal to the second preset temperature, it is indicated that the set temperature is higher, and the indoor temperature is easier to reach the set temperature. A higher set temperature indicates that the user does not like a low temperature, and at this time, one or both of the two indoor heat exchangers 143 are controlled to perform cooling operation according to the indoor temperature and the indoor humidity to balance the temperature demand and the humidity demand, thereby enabling the user to have a good humidity experience and temperature experience.

Further, in some alternative embodiments of the present invention, an electric heater 144 is disposed within each air channel 141. The first dehumidification strategy further comprises: at least the indoor heat exchanger corresponding to the air outlet 140 in the cooling operation is controlled to be turned on. "at least control the opening of the indoor heat exchanger corresponding to the air outlet 140 in the cooling operation" includes the following two cases: ① Controlling the indoor heat exchanger corresponding to the air outlet part 140 in the refrigeration operation to be started; ② The electric heaters 144 of both the air outlet portions 140 are controlled to be turned on.

In this embodiment, when the set temperature is less than the first preset temperature, the electric heating is turned on, so that the heating capacity of the electric heating is greater than or equal to the refrigerating capacity of the indoor heat exchanger 143, and constant-temperature dehumidification in the room can be achieved, so that the comprehensive use experience of the user can be further improved.

Further, compared with a mode of only starting one electric heater, the mode of starting two electric heaters simultaneously is more beneficial to realizing constant temperature dehumidification in a room, so that comprehensive use experience of a user is more beneficial to improvement.

As shown in fig. 3, in some alternative embodiments of the present invention, in the first dehumidification strategy, the step of controlling one of the two air outlets 140 to perform cooling operation and the other to perform non-operation or non-heat exchange operation includes the following steps:

S211, acquiring the indoor user position;

S212, controlling the air outlet part 140 far from the user position to perform refrigeration operation, and controlling the other air outlet part 140 to perform non-working or non-heat exchange operation.

When the air conditioner dehumidifies at a low temperature, the air outlet part 140 of the refrigeration operation is selected according to the user position, the air outlet part 140 far away from the user position is used as a refrigeration air outlet column, the dehumidification effect is ensured, the temperature experience of the user is improved, and the comprehensive use experience of the user is improved.

Preferably, S212 includes: the air outlet 140 far from the user position is controlled to perform cooling operation, and the other air outlet 140 is controlled to perform non-heat exchange operation. Compared with the mode that the other air outlet part 140 does not work, the other air outlet part 140 can output non-heat exchange air, so that the fluidity of indoor air can be improved, the uniformity of indoor temperature and humidity is facilitated, and rapid dehumidification is facilitated.

Further preferably, S212 includes: the air outlet portion 140 far from the user position is controlled to perform cooling operation, and the other air outlet portion 140 is controlled to perform non-heat exchange operation and operate according to high wind speed. For example, the non-heat exchanging operation of the air outlet 140 may be rotated at a maximum preset rotational speed.

As shown in fig. 4, in some alternative embodiments of the present invention, in the second dehumidification strategy, the controlling one or two cooling operations of the two air outlet portions 140 according to at least the indoor temperature and the indoor humidity may include the following steps:

S221, judging whether the temperature difference between the indoor temperature and the set temperature is smaller than a preset temperature difference value, and whether the humidity difference between the indoor humidity and the set humidity is larger than a preset humidity difference value; if yes, executing S222; if not, then S223 is performed;

s222, controlling one air outlet part 140 to perform refrigeration operation;

s223, controlling the two air outlet parts 140 to perform cooling operation.

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, and the humidity difference between the indoor humidity and the set humidity is greater than the preset humidity difference, the air outlet 140 is controlled to perform cooling operation, so that the air conditioner has a smaller cooling capacity, and thus shutdown or very low frequency operation caused by too fast temperature decrease can be prevented. In addition, compared with the cooling operation of the double air outlet portions 140, the cooling operation of the single air outlet portion 140 can reduce the total area of the indoor heat exchanger 143 by half, and the coil temperature can be significantly reduced, 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, or the humidity difference between the indoor humidity and the set humidity is not greater than the preset humidity difference, the requirement of the user on temperature is higher than the requirement on humidity, and at this time, the two air outlet parts 140 are controlled to perform refrigeration operation, so that the indoor environment temperature is reduced more conveniently and rapidly, and the user can have better comprehensive use experience.

Further, as shown in fig. 5, in some alternative embodiments of the present invention, S222, controlling a cooling operation of an air outlet portion 140 may include the following steps:

s2221, acquiring indoor user positions;

S2222, controlling the air outlet part 140 far from the user position to perform refrigeration operation, and controlling the other air outlet part 140 to perform non-working or non-heat exchange operation.

In this embodiment, according to the air outlet portion 140 of the refrigeration operation of user position selection, the air outlet portion 140 that will keep away from user position is regarded as the refrigeration air-out post, when guaranteeing dehumidification effect, is more favorable to promoting user's temperature experience, and then is favorable to promoting user's comprehensive use experience more.

Preferably, S2222 includes: the air outlet 140 far from the user position is controlled to perform cooling operation, and the other air outlet 140 is controlled to perform non-heat exchange operation. Compared with the mode that the other air outlet part 140 does not work, the other air outlet part 140 can output non-heat exchange air, so that the fluidity of indoor air can be improved, the uniformity of indoor temperature and humidity is facilitated, and rapid dehumidification is facilitated.

Further preferably, S2222 includes: the air outlet portion 140 far from the user position is controlled to perform cooling operation, and the other air outlet portion 140 is controlled to perform non-heat exchange operation and operate according to high wind speed. For example, the non-heat exchanging operation of the air outlet 140 may be rotated at a maximum preset rotational speed.

As shown in fig. 2, in some alternative embodiments of the present invention, S200, the performing the corresponding dehumidification strategy according to at least the set temperature may include the following steps:

S230, executing a third dehumidification strategy in response to the set temperature being greater than or equal to the first preset temperature and less than the second preset temperature; the third dehumidification strategy includes: both air outlet portions 140 are controlled to perform cooling operation.

Specifically, when the first preset temperature is less than or equal to the set temperature and less than the second preset temperature, the two air outlet portions 140 are controlled to perform refrigeration operation, so that the air conditioner has larger dehumidification and refrigeration capacity, and a user can have better comprehensive use experience.

In some alternative embodiments of the present invention, the controlling the cooling operation of the air outlet 140 away from the user location, and controlling the other air outlet 140 to be inactive or not to perform heat exchange operation includes: the air outlet part 140 far from the user position is controlled to perform cooling operation and air is discharged towards one side far from the user position. By the method, the use experience of the user can be further improved.

In some alternative embodiments of the present invention, the controlling the cooling operation of the air outlet 140 away from the user location, and controlling the other air outlet 140 to be inactive or not to perform heat exchange operation includes: the air outlet 140 near the user's location is controlled to perform a non-heat exchanging operation and an automatic air swing mode is performed. By the method, the fluidity of indoor air can be improved, so that the uniformity of indoor temperature and indoor humidity can be improved.

As shown in fig. 9, in some alternative embodiments of the present invention, the air conditioner further includes a flow path control device 115, and the flow path control device 115 is configured to control two indoor heat exchangers 143 to operate simultaneously or only one of the indoor heat exchangers 143 to operate, and when any one of the air outlet parts 140 does not perform air outlet, the corresponding indoor heat exchanger 143 does not operate.

Specifically, the two air outlet portions 140 are a first air outlet portion and a second air outlet portion, and the corresponding two indoor heat exchangers 143 are a first indoor heat exchanger and a second indoor heat exchanger, respectively. The first indoor heat exchanger and the second indoor heat exchanger are arranged in parallel. In some embodiments, as shown in fig. 9, the flow path control device 115 includes a three-way valve having three openings connected to the outlet of the restriction device 114, the inlet of the first indoor heat exchanger, and the inlet of the second indoor heat exchanger, respectively. Only one heat exchanger can be controlled to work or two heat exchangers can be controlled to work simultaneously by controlling the three-way valve.

In some alternative embodiments, the flow path control device comprises two ball valves, a first ball valve and a second ball valve, respectively, disposed in parallel. Wherein, the first ball valve is connected with the first indoor heat exchanger 143 in series, and the second ball valve is connected with the second indoor heat exchanger 143 in series. By controlling the first ball valve and the second ball valve, the operation of one indoor heat exchanger 143 or the simultaneous operation of two indoor heat exchangers 143 can be controlled.

In some embodiments of the present invention, as shown in fig. 9, the air conditioner 100 further includes a compressor 111, a four-way valve 112, an outdoor heat exchanger 113, and a throttle device 114. The restriction 114 is upstream of the indoor heat exchanger 143. Throttle device 114 is used to control the amount of working fluid entering indoor heat exchanger 143.
