The invention provides a refrigeration control method of an air conditioner. The refrigeration control method of the embodiment of the invention can be applied to wall-mounted air conditioners, cabinet air conditioners, window air conditioners, courtyard air conditioners or other various forms of air conditioners.
Fig. 1 is a schematic view of a cooling control method of an air conditioner according to an embodiment of the present invention, and fig. 2 is a schematic block diagram of an air conditioner according to an embodiment of the present invention.
As shown in fig. 1 and 2, 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.
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 to be low in the initial stage of cooling so as to cause the compressor to operate at a higher frequency, so that the cooling capacity of the air conditioner is larger, and the indoor temperature is more rapidly decreased, so that the indoor environment is separated from a hot state as soon as possible.
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, and the target temperature of cooling in the intermediate stage of cooling is higher than the first target temperature. That is, after the initial stage of cooling, the indoor ambient temperature has been significantly reduced, and if the air conditioner continues to perform cooling operation quickly and with high power, the power consumption of the compressor is large, and the power consumption of the air conditioner is too large. 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 refrigeration can be made variable and gradually decreased by 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: a preset PMV mode is run.
That is, when the preset second switching condition is satisfied, the indoor environment is judged to reach or substantially reach the comfortable temperature range required by the general user, and the air conditioner is switched to the preset PMV mode from the middle stage of refrigeration, so that the indoor temperature is finely adjusted and kept at the level enabling the human body to feel most comfortable.
The thermal comfort index PMV is an evaluation index commonly used in the air-conditioning industry for representing the thermal response of a human body, and is a thermal comfort evaluation index which has the widest application range and the highest recognition degree in the world at present. In a PMV evaluation system, besides four objective factors of relative humidity, temperature, air flow rate and average radiation temperature, which influence the thermal comfort of a human body, two subjective factors of thermal resistance of human body clothing and human body metabolism rate play very important roles. The PMV index indicates the average index of the user population for seven levels of thermo-sensory voting (-3, -2, -1, 0, 1, 2, 3).
The PMV mode of the air conditioner refers to an operation mode in which the air conditioner automatically adjusts an operation parameter of the air conditioner according to an environmental parameter such as a human PMV index and an indoor and outdoor ambient temperature so as to constantly and stably maintain the indoor temperature at a level that makes a human feel most comfortable. Since this PMV mode is widely used in the air conditioning industry, the detailed control scheme is not described herein.
In summary, 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. The rapid cooling is performed in the initial stage of cooling, so that the indoor environment temperature is rapidly reduced. And in the middle stage of refrigeration, the target refrigeration temperature is properly adjusted to reduce the power of the compressor. And finally, operating the PMV mode to finely adjust the indoor environment temperature so as to keep the indoor human body in a comfortable state all the time.
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 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.
Furthermore, in the refrigeration control method of the air conditioner, different fan rotating speed gears and air guide schemes 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.
Specifically, in some embodiments, the rotational 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. The fan 30 is used for causing indoor air to enter the shell of the air conditioner, so that cold air or hot air is formed after heat exchange between airflow and the heat exchanger is completed, and then the air is blown out through the air outlet. Specifically, during the initial stages of cooling, the fan 30 may be operated at a maximum rotational speed (otherwise referred to as the 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, the swing wind range of the air deflector 50 and the swing blade 60 of the air conditioner at the early stage of cooling is made larger than that at the middle stage of cooling. So as to spread the cold air in a wider range in the initial stage of refrigeration and accelerate the refrigeration speed. For example, in the early stage of cooling, the air deflector 50 and the swinging blade 60 swing air to and fro to the maximum extent, and in the middle stage of cooling, the air deflector 50 guides air upwards to make cold air flow upwards, so as to avoid the cold air from blowing directly to the human body and causing discomfort to the human body.
In some embodiments, when the PMV mode is operated, the air guide plate 50 of the air conditioner swings air up and down, so that indoor cold air is distributed more dispersedly, uneven cold and hot conditions are avoided, and the indoor environment is more comfortable.
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. 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 refrigeration reaches a second preset time or the indoor environment temperature is less than or equal to a second temperature threshold. 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.
The first temperature threshold is greater than the target temperature of the middle stage of refrigeration, and the second temperature threshold is less than the target temperature of the middle stage of refrigeration. For example, in one preferred embodiment, the first target temperature may be set at 22 ℃, the target temperature for refrigeration during the middle stage of refrigeration may be set at 24 ℃, the first temperature threshold may be set at 26 ℃, and the second temperature threshold may be set at 23 ℃.
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.
The air conditioner includes a controller 800, 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 executed by the processor 810 to implement a cooling control method of the air conditioner according to any one of the embodiments of the present invention.
Fig. 3 is a schematic structural view of an air conditioner according to an embodiment of the present invention; FIG. 4 is an enlarged schematic side view of the air conditioner shown in FIG. 3 with the air outlet area cut away; fig. 5 is a schematic view of the air conditioner shown in fig. 4 after the air guiding angle of the air deflector 50 is changed.
As shown in fig. 3 to 5, in some embodiments, the air conditioner is a wall-mounted air conditioner, and four air deflectors 50 are disposed at the air outlet 12, and each air deflector 50 is rotatably mounted to the casing 10 about a horizontal transverse axis. The four air deflectors 50 are arranged in two groups along the length direction of the casing 10, and each group includes two upper and lower air deflectors 50. In other words, the four air deflectors 50 are arranged in a matrix. The four air deflectors 50 are respectively matched with motors (not shown), and each motor is independently controlled by the controller 800. So, make the air conditioner more refine to the regulation of upper and lower air-out angle.
For example, as shown in fig. 4, both the upper air guide plate 50 and the lower air guide plate 50 may be swung to widen the swing angle range, or as shown in fig. 5, the lower air guide plate 50 may be set to the closed position, and the upper air guide plate 50 may be moved upward. Of course, more air guiding modes can be obtained by combining the air guiding angles of the four air guiding plates 50, which is not described in detail herein.
Thus, it should be appreciated by those skilled in the art that while various exemplary embodiments of the invention have been shown and described in detail herein, many other variations or modifications which are consistent with the principles of this invention may be determined or derived directly from the disclosure of the present invention without departing from the spirit and scope of the invention.
