One aspect of the present invention provides a refrigeration control method for an air conditioner. The refrigeration control method in the embodiment of the present invention can be applied to wall-mounted units, cabinet units, window units, patio units, or other various forms of air conditioners.

The air conditioner in the embodiment of the present invention includes a plurality of air deflectors 50 for guiding the up and down air outlet angles of the air outlets 12 . For example, as shown in FIG. 3 , the plurality of air deflectors 50 can be divided into multiple groups (two groups in the figure) along the lateral direction of the housing 10 , and each group includes two upper and lower air deflectors 50 . Each wind deflector 50 is rotatably mounted on the casing 10 around a horizontal axis. Each wind deflector 50 is matched with a motor (not shown), and each motor is independently controlled by the controller 800 . In this way, the adjustment of the air conditioner to the upper and lower air outlet angles is more refined.

Fig. 1 is a schematic diagram of a refrigeration control method for an air conditioner according to an embodiment of the present invention; Fig. 2 is a schematic block diagram of an air conditioner according to an embodiment of the present invention; Fig. 3 is a schematic structural diagram of an air conditioner according to an embodiment of the present invention; Fig. 4 It is a schematic enlarged side view of the air conditioner shown in Figure 3 when the air outlet area is cut; Figure 5 is the air conditioner shown in Figure 3 when the left wind deflector is closed and the right wind deflector is at the upper wind deflecting angle Figure 6 is a schematic enlarged side view of the air conditioner shown in Figure 5 when it is cut in the air outlet area.

As shown in Fig. 1 to Fig. 6, the refrigeration control method of the air conditioner according to the embodiment of the present invention includes:

Step S102: receiving an instruction to enable the intelligent temperature control mode.

Specifically, when the user wants the air conditioner to operate in the intelligent temperature control mode, the user can perform corresponding operations on the remote control, wire controller, control panel of the air conditioner main unit, or other intelligent terminal devices that are wirelessly connected to the air conditioner, so that the air conditioner controller 800 Issue the start command of the intelligent temperature control mode.

Step S104: Run the initial cooling stage.

That is, when the controller 800 of the air conditioner receives the command to turn on the intelligent temperature control mode, it controls the air conditioner to enter the initial stage of cooling. In the initial stage of cooling, the preset first target temperature is used as the cooling target temperature. And, make each wind deflector 50 reciprocate and swing the wind in the maximum range.

In this step, the first target temperature is lower than the cooling target temperature generally set by users. For example, generally users are accustomed to setting the cooling target temperature between 25°C and 29°C, so the first target temperature may be set between 18°C and 23°C, for example, 22°C. In the initial stage of refrigeration, the cooling target temperature is set lower, so as to promote the compressor to run at a higher frequency, so that the cooling capacity of the air conditioner is greater, and the indoor temperature drops faster, so that the indoor environment can get out of the hot state as soon as possible. Make each air deflector 50 reciprocate and swing air in the largest range, so that the cold air can diffuse in a wider range and speed up the cooling speed. Further, the swing blade 60 can also be made to swing back and forth in a maximum range.

Step S106: Judging whether a preset first switching condition is met. If yes, execute step S108; if not, return to execute step S104.

Step S108: Run the mid-refrigeration stage.

That is, when the preset first switching condition is met, the air conditioner is switched from the initial stage of cooling to the middle stage of cooling. The cooling target temperature in the mid-refrigeration stage is higher than the first target temperature, and each air guide plate 50 is rotated to the upper air guide angle, so as to guide the outlet air flow upwards and avoid cold wind from blowing people.

After the initial stage of refrigeration, the indoor ambient temperature has dropped significantly. If the air conditioner continues to operate rapidly and with high power, the power consumption of the compressor will be large, and the power consumption of the air conditioner will be too large. Therefore, when the preset first switching condition is satisfied, the air conditioner is switched to the mid-refrigeration stage in time, the cooling target temperature is increased, and the frequency of the compressor is reduced. For example, in an optional solution, the first target temperature may be set to 22°C, and the cooling target temperature in the mid-refrigeration stage may be set to 24°C.

In some embodiments, the cooling target temperature is constant throughout the mid-cooling phase. In some other embodiments, the cooling target temperature in the mid-cooling stage can also be made a variable, so that it shows a decreasing trend according to a preset function.

Step S110: Determine whether a preset second switching condition is met. If yes, execute step S112; if not, return to execute step S108.

Step S112: Run the stable running phase.

That is, when the preset second switching condition is met, it is judged that the indoor environment has reached or basically reached the comfortable temperature range required by general users, and then the air conditioner is switched from the mid-cooling stage to the preset stable operation stage. In this stable operation stage, the cooling target temperature is made higher than the first target temperature and part of the air deflector 50 is closed. Here, closing a certain wind deflector 50 refers to turning the wind deflector 50 to the position of closing the air outlet 12 , refer to the wind deflector 50 on the left side of FIG. 5 . For example, a set of wind deflectors 50 may be closed. In this way, the air volume of the air conditioner is further reduced, the indoor environment is kept in a low wind state, and the human body feels more comfortable. The cooling target temperature in the stable operation stage is greater than or equal to the cooling target temperature in the cooling middle stage, so that the compressor can be kept running at a low frequency.

In addition, in the stable operation stage, the unclosed wind deflector 50 can be kept at an upper wind deflecting angle, as shown in FIG. 5 , so as to keep at an angle that does not blow people.

In short, in the refrigeration control method of the air conditioner in the embodiment of the present invention, the air conditioner has an intelligent temperature control mode, and the intelligent temperature control mode is divided into multiple operation stages, and different operation stages play different roles. Rapid cooling is carried out in the initial stage of cooling, so that the air deflector 50 swings the wind back and forth in the maximum range, so that the indoor ambient temperature drops rapidly. In the mid-refrigeration stage, appropriately increase the cooling target temperature to reduce the power of the compressor, and keep the air deflector 50 at the upper air deflecting angle, so as to avoid the cold wind blowing directly on the human body. In the stable operation stage, part of the air deflectors 50 are closed to further reduce the air volume of the air conditioner, keep the indoor environment in a low wind state, and make the human body feel more comfortable.

The embodiment of the present invention not only realizes the rapid cooling of the indoor environment, but also meets the user's comfort requirements, and also saves the energy consumption of the air conditioner, and realizes the goal of energy saving and emission reduction. In addition, the refrigeration control method of the embodiment of the present invention realizes intelligent temperature control and automatic adjustment, which saves the user from the trouble of repeatedly adjusting various parameters, and enhances the user's intelligent experience.

Furthermore, in the refrigeration control method of the air conditioner of the present invention, different fan speed gears are designed for different operation stages, so as to match the respective cooling targets of each operation stage and achieve the optimal cooling effect. The fan 30 is used to force the indoor air to enter the casing 10 , so that the air flow and the heat exchanger complete heat exchange to form cold or hot air, and then blow out through the air outlet 12 .

Specifically, in some embodiments, the rotation speed of the fan 30 of the air conditioner in the early stage of cooling is greater than that in the middle stage of cooling. Specifically, in the initial stage of cooling, the fan 30 can be operated at the maximum speed (or called the strongest wind gear). In the mid-refrigeration stage, the fan 30 can be operated at a middle speed (or called a middle wind speed).

In some embodiments, in the stable operation stage, the fan speed of the air conditioner is adjusted according to the indoor ambient temperature. That is to say, when the indoor ambient temperature is at a higher level, a higher fan speed is used to appropriately accelerate the cooling speed. When the indoor ambient temperature is at a low level, a lower fan speed is used. The air conditioner may be provided with a temperature detection module 40 for detecting the indoor ambient temperature. The temperature detection module 40 can be a temperature sensor.

In some embodiments, the aforementioned first switching condition is: the running time of the initial cooling stage reaches the first preset duration or the indoor ambient temperature is less than or equal to the first temperature threshold, and the first temperature threshold is greater than the cooling target temperature in the middle cooling stage. That is, if one of the two conditions is met, it can be determined that the first switching condition is met.

The second switching condition is: the running time of the mid-cooling stage reaches a second preset duration or the difference between the indoor ambient temperature and the cooling target temperature of the mid-cooling stage is less than or equal to the preset difference.

For example, in a preferred embodiment, the first target temperature can be set to 22°C, the cooling target temperature in the mid-refrigeration stage can be set to 24°C, and the first temperature threshold can be set to 26°C. Make the preset difference 1°C. When the indoor ambient temperature is less than or equal to 23°, the difference between the indoor ambient temperature and the cooling target temperature is less than or equal to 1° C., and the second switching condition is met.

The value range of the first preset duration is 1 min to 5 min, for example, 3 min. The value range of the second preset duration is 18 minutes to 22 minutes, for example, 20 minutes. The first preset duration is shortened to avoid long-term high-frequency operation of the compressor, resulting in overcooling of the indoor temperature and excessive energy consumption of the compressor.

Another aspect of the present invention provides an air conditioner. The present invention does not impose any limitation on the form of the air conditioner, and the air conditioner may be a wall-mounted unit, a cabinet unit, a window unit, a patio unit or other various forms of air conditioners.

As shown in FIGS. 3 to 6 , the air conditioner according to the embodiment of the present invention may generally include a casing 10 , a plurality of wind deflectors 50 and a controller 800 .

The housing 10 is provided with an air outlet 12 for blowing out cold air. Each wind deflector 50 is rotatably mounted on the casing 10 for guiding the up and down air outlet angles of the air outlet 12 . For example, as shown in FIG. 3 , the plurality of air deflectors 50 can be divided into multiple groups along the lateral direction of the casing 10 , and each group includes two upper and lower air deflectors 50 . For example, as shown in FIG. 3 , they are divided into two groups, with a total of four wind deflectors 50 . For example, as shown in FIG. 4 , both the wind deflector 50 on the upper side and the wind deflector 50 on the lower side can be swung to expand the swing angle range. Alternatively, as shown in FIG. 5 and FIG. 6 , a group of wind deflectors 50 on the left side can be closed so that the right wind deflector 50 is at an upper wind deflecting angle. Of course, more wind guiding modes can also be obtained by combining the wind guiding angles of the various wind guiding plates 50 , which will not be repeated here.

The controller 800 includes a processor 810 and a memory 820. The memory 820 stores a computer program 821. When the computer program 821 is executed by the processor 810, it is used to implement the refrigeration control method of the air conditioner in any embodiment of the present invention.
