The invention provides a refrigeration control method of an air conditioner. The refrigeration control method provided by the embodiment of the invention can be applied to wall-mounted air conditioners, cabinet air conditioners, window air conditioners, courtyard air conditioners or other air conditioners in various forms.
The air conditioner according to the embodiment of the present invention includes a plurality of air deflectors 50 for guiding the upper and lower air outlet angles of the air outlet 12. For example, as shown in fig. 3, the plurality of wind deflectors 50 may be divided into a plurality of groups (two groups are shown) along the transverse direction of the casing 10, and each group includes two wind deflectors 50. Each air deflection plate 50 is rotatably mounted to the housing 10 about a horizontal transverse axis. Each air deflector 50 is individually coupled to a motor (not shown), and each motor is individually controlled by the controller 800. So, make the air conditioner more refine to the regulation of upper and lower air-out angle.

As shown in fig. 1 to 6, a refrigeration control method of an air conditioner according to an embodiment of the present invention includes:
step S102: and receiving an opening instruction of the intelligent temperature control mode.
Specifically, when the user wants to operate the air conditioner in the intelligent temperature control mode, the user can perform corresponding operations on the remote controller, the line controller, the control panel of the air conditioner host, or other intelligent terminal devices wirelessly connected to the air conditioner, so that the user can send an opening instruction of the intelligent temperature control mode to the controller 800 of the air conditioner.
Step S104: and operating the initial stage of refrigeration.
That is, after the controller 800 of the air conditioner receives the start instruction of the intelligent temperature control mode, the air conditioner is controlled to enter the initial stage of cooling, and in the initial stage of cooling, the preset first target temperature is used as the target temperature of cooling. Then, each air guide plate 50 is caused to swing air to and fro within the maximum range.
In this step, the first target temperature is lower than the cooling target temperature set by the general user. For example, a general user is used to set the target cooling temperature between 25 ℃ and 29 ℃, so the first target temperature may be set between 18 ℃ and 23 ℃, for example, 22 ℃. The target cooling temperature is set lower in the initial cooling stage to cause the compressor to operate at a higher frequency, so that the cooling capacity of the air conditioner is greater, and the indoor temperature is lowered more rapidly to bring the indoor environment out of a hot state as soon as possible. The air deflectors 50 are made to swing air in a reciprocating manner in the maximum range, so that cold air can be diffused in a wider range, and the refrigerating speed is increased. Further, the swinging blade 60 can swing wind to and fro within the maximum range.
Step S106: and judging whether a preset first switching condition is met. If yes, go to step S108; if not, the process returns to step S104.
Step S108: and operating the middle stage of refrigeration.
That is, when a preset first switching condition is satisfied, the air conditioner is switched from the initial stage of cooling to the intermediate stage of cooling. The target temperature of the middle stage of the refrigeration is higher than the first target temperature, and the air deflectors 50 are rotated to the upper air guiding angle, so that the air flow is guided upwards to prevent cold air from blowing people.
After the initial stage of refrigeration, the indoor environment temperature is obviously reduced, and if the air conditioner is continuously refrigerated and operated quickly and in a high-power mode, the power consumption of the compressor is high, and the power consumption of the air conditioner is too high. Therefore, when the preset first switching condition is met, the air conditioner is switched to operate at the middle stage of refrigeration in time, the target refrigeration temperature is increased, and the frequency of the compressor is reduced. For example, in an alternative arrangement, the first target temperature may be set at 22 ℃ and the target temperature for refrigeration during the intermediate stage of refrigeration may be set at 24 ℃.
In some embodiments, the target temperature of refrigeration throughout the mid-stage of refrigeration is constant. In other embodiments, the target temperature of the middle stage of the cooling may be set as a variable, and the target temperature may be set to decrease in a preset function.
Step S110: and judging whether a preset second switching condition is met. If yes, go to step S112; if not, the process returns to step S108.
Step S112: and (5) operating in a stable operation stage.
That is, when the preset second switching condition is satisfied, it is determined that the indoor environment has reached or substantially reached the comfortable temperature range required by the general user, and the air conditioner is switched from the middle stage of cooling to the preset stable operation stage. In this steady operation phase, the cooling target temperature is made higher than the first target temperature and part of the air deflection plates 50 are closed. Here, turning off a certain air deflector 50 refers to turning the air deflector 50 to a position where the air outlet 12 is closed, and refer to the air deflector 50 on the left side of fig. 5. For example, a set of louvers 50 may be turned off. Therefore, the air volume of the air conditioner is further reduced, the indoor environment is kept in a low-air state, and the human body feels more comfortable. The target cooling temperature in the stable operation stage is greater than or equal to the target cooling temperature in the middle stage of cooling so as to keep the compressor operating at a low frequency.
In addition, in the stable operation stage, the air guide plate 50 which is not closed can be kept at the upper air guide angle, as shown in fig. 5, so as to be kept at the angle of not blowing people.
In a word, in the refrigeration control method of the air conditioner according to the embodiment of the present invention, the air conditioner has an intelligent temperature control mode, the intelligent temperature control mode is divided into a plurality of operation stages, and different operation stages play different roles. In the initial stage of cooling, the air deflector 50 swings air to and fro in the maximum range, so that the indoor environment temperature is rapidly reduced. In the middle stage of refrigeration, the target temperature of refrigeration is properly increased to reduce the power of the compressor, so that the air deflector 50 keeps an upward air guiding angle to prevent cold air from directly blowing to a human body. In the stable operation stage, part of the air deflectors 50 are closed, so that the air volume of the air conditioner is further reduced, the indoor environment is kept in a low-air state, and the human body feels more comfortable.
The embodiment of the invention not only realizes the rapid cooling of the indoor environment, but also can meet the comfort requirement of a user, and also saves the energy consumption of the air conditioner and realizes the aims of energy conservation and emission reduction. In addition, the refrigeration control method of the embodiment of the invention realizes intelligent temperature control and automatic adjustment, avoids the trouble of repeatedly adjusting various parameters of a user, and enhances the intelligent experience of the user.
Further, in the refrigeration control method of the air conditioner, different fan rotating speed gears are designed for different operation stages so as to be matched with respective refrigeration targets of the operation stages, and the optimal refrigeration effect is achieved. The fan 30 is used for causing indoor air to enter the housing 10, so that cold air or hot air is formed after the air flow exchanges heat with the heat exchanger, and then the cold air or the hot air is blown out through the air outlet 12.
Specifically, in some embodiments, the rotation speed of the blower 30 of the air conditioner is made greater at the early stage of cooling than at the middle stage of cooling. Specifically, during the initial stages of cooling, the fan 30 may be operated at a maximum rotational speed (otherwise referred to as a maximum wind range). During the mid-stage of cooling, the fan 30 may be operated at an intermediate rotational speed (alternatively referred to as an intermediate gear).
In some embodiments, during the stable operation phase, the fan speed of the air conditioner is adjusted according to the indoor ambient temperature. That is, when the indoor ambient temperature is at a higher level, a higher fan rotation speed is adopted to appropriately accelerate the cooling speed. When the indoor environment temperature is in a lower grade, a lower fan rotating speed is adopted. The air conditioner may be provided with a temperature detection module 40 for detecting an indoor ambient temperature. The temperature detection module 40 may be a temperature sensor.
In some embodiments, the first switching condition is: the operation time of the initial stage of refrigeration reaches a first preset time or the indoor environment temperature is less than or equal to a first temperature threshold, and the first temperature threshold is greater than the target temperature of refrigeration in the middle stage of refrigeration. That is, it can be determined that the first switching condition is satisfied when one of the two conditions is satisfied.
The second switching condition is: the operation time of the middle stage of the refrigeration reaches a second preset time or the difference between the indoor environment temperature and the target temperature of the middle stage of the refrigeration is less than or equal to a preset difference.
For example, in a preferred embodiment, the first target temperature may be set at 22 ℃, the target temperature for cooling at the middle stage of cooling may be set at 24 ℃, and the first temperature threshold may be set at 26 ℃. The preset difference was made to be 1 ℃. When the indoor environment temperature is less than or equal to 23 degrees, the difference value between the indoor environment temperature and the refrigeration target temperature is less than or equal to 1 ℃, and the second switching condition is met.
The first preset time period ranges from 1min to 5min, for example, 3min. The second preset time period ranges from 18min to 22min, for example, 20min. The first preset time is shorter, so that the phenomenon that the compressor operates at high frequency for a long time to cause the supercooling of indoor temperature and the overhigh energy consumption of the compressor is avoided.
Another aspect of the present invention provides an air conditioner. The form of the air conditioner is not limited in any way, and the air conditioner can be a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a courtyard machine or other various forms of air conditioners.
As shown in fig. 3 to 6, the air conditioner according to the embodiment of the present invention may generally include a case 10, a plurality of air deflectors 50, and a controller 800.
The housing 10 is provided with an air outlet 12 for blowing out a cool air flow. Each of the wind deflectors 50 is rotatably installed on the housing 10 for guiding the wind outlet 12 to wind upward and downward. For example, as shown in fig. 3, the plurality of air deflectors 50 may be divided into a plurality of groups along the transverse direction of the casing 10, each group including two upper and lower air deflectors 50. For example, as shown in fig. 3, the air guiding plates 50 are divided into two groups, and the total number is four. For example, as shown in fig. 4, the upper air guide plate 50 and the lower air guide plate 50 can be swung to expand the swing angle range. As shown in fig. 5 and 6, the left air guiding plate 50 may be closed to make the right air guiding plate 50 at the upper air guiding angle. Certainly, more air guiding modes can be obtained by combining the air guiding angles of the air guiding plates 50, which is not described in detail herein.
The controller 800 includes a processor 810 and a memory 820, the memory 820 stores a computer program 821, and the computer program 821 is used to implement the cooling control method of the air conditioner according to any embodiment of the present invention when the computer program 821 is executed by the processor 810.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
