Detailed ways

The embodiments of the present invention are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

An air conditioner and a control method and apparatus thereof according to embodiments of the present invention will be described below with reference to the accompanying drawings.

1 is a flow chart of a method of controlling an air conditioner according to an embodiment of the present invention.

As shown in FIG. 1 , a method for controlling an air conditioner according to an embodiment of the present invention includes the following steps:

S1, after the air conditioner enters the comfortable humidity mode and runs stably, the indoor ambient temperature and the indoor heat exchanger coil temperature are obtained.

When the air conditioner is operated in a comfortable humidity mode, the air conditioner can adjust the humidity in the room to meet the user's comfort requirements. The comfortable humidity mode can be a separate mode set by the user, for example, the air conditioner can be controlled to enter the comfortable humidity mode by triggering a mode switching button on the remote controller of the air conditioner or a button corresponding to the comfort humidity mode setting. The comfortable humidity mode can also be an additional mode in any operation mode of the air conditioner set by the user. For example, when the user sets the heating mode, the heating mode is added with a comfortable humidity mode, so that not only heating but also adjustment can be performed. The indoor temperature can also adjust the humidity in the room.

In an embodiment of the present invention, the air conditioner can be stably operated when the time when the air conditioner operates in the comfortable humidity mode reaches a preset time threshold.

The air conditioner of the embodiment of the invention may include an indoor ambient temperature sensor and an indoor heat exchanger coil temperature sensor corresponding to the indoor heat exchanger coil to detect the indoor ambient temperature and the indoor heat exchanger coil temperature, respectively.

S2, calculating a temperature difference between the indoor ambient temperature and the indoor heat exchanger coil temperature.

S3, controlling the air conditioner to perform humidification work or dehumidification work according to the temperature difference.

Specifically, the temperature difference may be determined. If the temperature difference is greater than the first preset value, the indoor humidity may be determined to be too low, and thus the humidifying device of the air conditioner may be controlled to be turned on for a first preset time to perform humidification.

If the temperature difference is less than or equal to the first preset value and greater than the second preset value, it may be determined that the indoor humidity is appropriate, that is, within the comfortable humidity range, and thus the air conditioner can be controlled to maintain the current operating state. The second preset value is smaller than the first preset value. In an embodiment of the invention, the first preset value is 14 to 16 ° C, and the second preset value is 11 to 13 ° C.

If the temperature difference is less than or equal to the second preset value and greater than the third preset value, it may be determined that the indoor humidity is slightly higher, so that the indoor fan speed of the air conditioner can be controlled to be reduced, so that the air conditioner performs the dehumidification work in the first manner; If the temperature difference is less than the third preset value, it can be determined that the indoor humidity is too high, and thus the dehumidification device of the air conditioner can be controlled to be turned on for a first preset time, so that the air conditioner performs the dehumidification work in the second manner. The third preset value is smaller than the second preset value. In one embodiment of the invention, the third predetermined value is 7 to 9 °C.

Relatively speaking, the humidity when the indoor humidity is slightly higher is lower than the humidity when the indoor humidity is too high. Therefore, when it is determined that the indoor humidity is slightly high, that is, when the moisture content in the current indoor room is not particularly high, the rotation speed of the indoor fan can be lowered. The temperature of the indoor heat exchanger, when the temperature of the indoor heat exchanger is lower than the dew point temperature of the current indoor air, the indoor heat exchanger has a certain dehumidification function, which plays a simple dehumidification effect, thereby achieving the speed of the indoor fan The purpose of small dehumidification is convenient and fast. For example, the first preset speed may be reduced by 5% to 15% based on the current indoor fan speed to enable the air conditioner to perform dehumidification in the first dehumidification mode. However, when it is determined that the humidity in the room is too high, that is, when the moisture content in the current room is high, the speed of the indoor fan can be reduced to a small dehumidification effect, but the humidity cannot be greatly reduced, so The dehumidification device realizes a large amount of dehumidification in the room, that is, the air conditioner operates in the second dehumidification mode to realize rapid dehumidification in the room and ensure the comfort of the indoor humidity. And during the dehumidification process, the indoor fan can run at normal speed.

In an embodiment of the present invention, the humidifying device may be an air conditioner independent of the air conditioner, and the humidifier communicates with the air conditioner, so that when the humidifying action needs to be performed, the start signal is sent to the humidifier through the air conditioner to control The humidifier starts to humidify; when it is not necessary to perform the humidification action, a stop signal is sent to the humidifier through the air conditioner to control the humidifier to stop humidification. In addition, the humidifying device may also be integrated into the humidifying component in the air conditioner. For example, the humidifying component includes a watering device disposed on the indoor heat exchanger, and when the humidifying action needs to be performed, the watering device is controlled to be exposed to the indoor heat exchanger. Water; when the humidification action is not required, the drenching device is controlled to stop watering.

In one embodiment of the present invention, the dehumidification apparatus includes a dehumidification valve disposed corresponding to the indoor heat exchanger, wherein the throttling operation is controlled by the dehumidification valve, and the throttle element is controlled to be fully open to cause the air conditioner to be dehumidified by the second The way to dehumidify.

Specifically, the air conditioner includes a compressor, an outdoor heat exchanger, a throttle element, and an indoor heat exchanger connected in sequence, and an indoor fan correspondingly disposed on the indoor heat exchanger, wherein the refrigerant pipeline of the indoor heat exchanger includes In two parts, a part of the refrigerant pipeline is directly connected to the throttle element and the compressor at one end; the other part of the refrigerant pipeline is connected to the throttle element through a dehumidification valve, and the other end is connected to the compressor.

By controlling the throttling element in the above structure to be in the fully open state, and controlling the dehumidification valve to perform the throttling operation, the dehumidification device is controlled to be turned on. At this time, the high-temperature and high-pressure gaseous refrigerant from the compressor is converted into a high-temperature and high-pressure liquid refrigerant after being exchanged by the outdoor heat exchanger, and then a part of the high-temperature and high-pressure liquid refrigerant directly enters a part of the refrigerant pipe of the indoor heat exchanger for heat exchange. The low-temperature and low-pressure liquid refrigerant is returned to the compressor; the other part of the high-temperature and high-pressure liquid refrigerant is thawed by the dehumidification valve, and then becomes a low-temperature low-pressure liquid refrigerant, and then flows back through another part of the refrigerant pipe of the indoor heat exchanger. To the compressor. Among them, a part of the refrigerant pipe of the indoor heat exchanger is used as a condenser to realize heating of the room, and another part of the refrigerant pipe is used as an evaporator to realize a large amount of dehumidification indoors, thereby achieving constant temperature dehumidification indoors and ensuring indoor humidity comfort. Sex.

When it is not necessary to control the dehumidification device to be turned on, the dehumidification valve is controlled to be fully open, and the throttling element is controlled to perform the throttling operation, that is, the control throttling element returns to the normal working state.

Therefore, a large amount of dehumidification function of the air conditioner can be realized by providing a corresponding dehumidification valve in the air conditioner, and the method is simple and easy to implement.

The comfortable humidity mode may be a separate mode set by the user, for example, the air conditioner may be controlled to enter the comfortable humidity mode by triggering a mode switching button on the remote controller of the air conditioner or a button corresponding to the comfort humidity mode setting. The comfortable humidity mode can also be an additional mode in any operation mode of the air conditioner set by the user. For example, when the user sets the heating mode, the heating mode is added with a comfortable humidity mode, so that not only heating but also adjustment can be performed. The indoor temperature can also adjust the humidity in the room.
