Detailed Description
First, it should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention. And can be adjusted as needed by those skilled in the art to suit particular applications. For example, although the mute operation control method of the present invention is described in conjunction with an air conditioner, this is not limiting, and other heat exchange devices with similar mute operation requirements may also operate the mute operation control method of the present invention, such as a heat exchange water heater, a heat exchange dehumidifier, etc.
Secondly, it should be noted that in the description of the present invention, although the individual steps of the control method of the present invention are described in a specific order in the present application, these orders are not limiting, and a person skilled in the art may perform the steps in a different order without departing from the basic principle of the present invention.
Based on the problems that the existing physical noise reduction mode pointed out in the background art is not ideal in noise reduction effect and difficult to realize the mute operation of the air conditioner, the invention provides a mute operation control method of the air conditioner, aiming at fundamentally eliminating most of the operation noise of the air conditioner and achieving the aim of enabling the air conditioner to operate in a mute mode.
Generally, an air conditioner is operated with a fixed system pressure that meets the normal operating requirements of the air conditioner. When the air conditioner is operated, the actual system pressure is adjusted in real time by referring to the fixed system pressure, so that the actual system pressure is always close to (or equal to) the fixed system pressure, and the normal operation of the air conditioner is ensured.
The air conditioner of the present invention includes a normal operation mode and a silent operation mode, wherein the normal operation mode matches a normal system pressure, which is a fixed system pressure corresponding to the normal setting of the air conditioner. The silent operation mode is matched with a preset silent pressure which is a set pressure value greater than the pressure of the conventional system.
Referring to fig. 1, fig. 1 is a flow chart illustrating major steps of a method for controlling a mute operation of an air conditioner according to the present invention. As shown in fig. 1, the method for controlling a mute operation of an air conditioner of the present invention includes:
step S1: acquiring the current system pressure of the air conditioner;
step S2: comparing the current system pressure with a preset mute pressure;
step S3: and selectively reducing the rotating speed of the outdoor fan according to the comparison result of the current system pressure and the preset mute pressure so as to enable the air conditioner to operate based on the mute operation mode.
In the above step S2, the mute pressure is preset as a critical pressure value set for dividing the normal operation mode and the mute operation mode of the air conditioner. When the air conditioner is in a normal operation mode, the actual system pressure of the air conditioner is continuously adjusted to a direction close to the normal system pressure and is always below the critical pressure value; when the air conditioner is in the silent operation mode, the actual system pressure of the air conditioner is continuously adjusted to a direction close to the preset silent pressure value, and is not lower than the critical pressure value all the time.
In step S3, considering that the system pressure of the air conditioner is closely related to the rotation speed of the outdoor fan, specifically: when the rotating speed of the outdoor fan is reduced, the flowing degree of the airflow at the outdoor side is reduced, and the heat exchange efficiency of the outdoor heat exchanger of the air conditioner is reduced, so that the transformation amount (such as liquefaction amount) of the refrigerant in the outdoor heat exchanger in unit time is reduced, and the system pressure of the air conditioner is increased. Therefore, if the air conditioner sets a larger value of the system pressure, the outdoor fan is operated at a higher rotation speed when the air conditioner approaches the system pressure.
In this case, by comparing the current system pressure with the preset mute pressure, the magnitude of the numerical difference between the current system pressure and the preset mute pressure can be confirmed. The rotating speed of the outdoor fan is selectively reduced according to the value difference, and the actual system pressure of the air conditioner can be ensured to be not lower than the preset mute pressure and to be within the range of the system pressure corresponding to the mute operation mode (namely, the actual system pressure is more than or equal to the preset mute pressure), so that the air conditioner is ensured to be in the mute operation mode, and the air conditioner is prevented from generating obvious working noise due to the fact that the air conditioner operates at the higher rotating speed of the outdoor fan.
In the above steps S1 to S3, the adjustment requirement of the rotational speed of the outdoor fan of the air conditioner can be determined by comparing the current system pressure of the air conditioner with the preset mute pressure, so that the system pressure of the air conditioner is continuously adjusted in comparison with the preset mute pressure, and the rotational speed of the outdoor fan of the air conditioner is always in a lower rotational range, thereby achieving the purpose of enabling the air conditioner to operate in a mute manner.
In the above embodiment, it should be noted that neither the conventional system pressure nor the mute preset pressure is limited, and a person skilled in the art may set specific values of the conventional system pressure and the mute preset pressure according to functional parameters of the air conditioner, actual operation requirements of the air conditioner, and the like.
In a preferred embodiment, the mute operation mode includes at least two mute levels, and each mute level is respectively matched with a preset mute pressure. For example, the mute operation mode includes a first-stage mute stage and a second-stage mute stage having a greater mute effect than the first-stage mute stage, and the preset mute pressure P1 corresponding to the first-stage mute stage is greater than the normal system pressure P0 and less than the preset mute pressure P2 corresponding to the second-stage mute stage. From the first-level mute gear to the second-level mute gear, the mute effect becomes stronger. When the air conditioner operates, a specific mute gear in a mute operation mode can be selected according to actual mute requirements.
In this case, the step S2 specifically includes:
obtaining a preset mute pressure corresponding to the current mute gear according to the current mute gear;
comparing the current system pressure with a preset mute pressure corresponding to the current mute gear;
in the above steps, since the current mute level is determined according to the current actual mute requirement of the air conditioner, such as a default mute level set by a user or a default mute level set in a mute operation mode in a system of the air conditioner, the current mute level of the air conditioner is determined each time the air conditioner starts to perform mute operation, and thus the corresponding preset mute pressure is also determined. In this case, when the above steps are executed, only the currently matched preset mute pressure needs to be directly called.
The step S3 specifically includes:
and if the current system pressure is smaller than the preset mute pressure corresponding to the current mute gear, reducing the rotating speed of the outdoor fan so as to adjust the current system pressure to the preset mute pressure corresponding to the current mute gear.
In the above steps, when the air conditioner is in any mute shift of the mute operation mode, the current actual system pressure of the air conditioner needs to be selectively adjusted in comparison with the preset mute pressure in the mute shift.
Taking the current mute gear as the first-stage mute gear as an example, when the current system pressure is less than the preset mute pressure P1 corresponding to the first-stage mute gear, it is indicated that the current system pressure is not in the system pressure interval [ P1, P2) corresponding to the first-stage mute gear, and does not meet the operation standard of the first-stage mute gear. Therefore, the rotation speed of the outdoor fan is reduced to increase the current system pressure, so that the current system pressure is urged to approach the preset mute pressure P1, and thus falls within the system pressure interval corresponding to the one-stage mute stage.
Further, the step S3 includes:
and if the current system pressure is greater than or equal to the preset mute pressure corresponding to the current mute gear, the rotating speed of the outdoor fan is not reduced, and the air conditioner is enabled to maintain the current system pressure to operate.
Taking the current operation gear as the first-stage mute gear as an example, in the above step, when the current system pressure is not less than the preset mute pressure P1, it is indicated that the mute effect of the air conditioner in the current operation is at least not less than the mute effect of the first-stage mute gear, and the mute requirement corresponding to the first-stage mute gear can be met, so that the rotating speed of the outdoor fan does not need to be reduced to adjust the value of the current system pressure.
In a possible embodiment, the silent operation mode only includes one silent gear, i.e. the silent operation mode only matches a preset silent pressure, and the air conditioner only corresponds to a silent effect in the silent operation mode.
In this case, the step S3 specifically includes:
and if the current system pressure is smaller than the preset mute pressure, reducing the rotating speed of the outdoor fan so as to adjust the current system pressure to the preset mute pressure.
Further, the step S3 includes:
and if the current system pressure is greater than or equal to the preset mute pressure, the rotating speed of the outdoor fan is not reduced, and the air conditioner is enabled to maintain the current system pressure to operate.
Preferably, after step S3, the method for controlling a silent operation of an air conditioner according to the present invention further comprises:
after the preset time, acquiring the current unit operation load of the air conditioner;
determining a numerical value interval of the current unit operation load;
and selectively correcting the system pressure of the air conditioner according to the numerical value interval of the current unit operation load.
In the above steps, the difference between the current unit operation effect of the air conditioner and the actual operation requirement can be determined through the numerical value interval where the current unit operation load of the air conditioner is located. Correcting the system pressure of the air conditioner according to the difference can avoid the reduction of the operation effect of the air conditioner due to the pursuit of the mute effect.
For example, the preset time may be set to 5 min.
In a preferred embodiment, the silent operation mode is the above-mentioned case comprising at least two silent gear steps, each silent gear step being respectively matched with a preset silent pressure,
the step of selectively correcting the system pressure of the air conditioner according to the numerical value interval of the current unit operation load comprises the following steps:
and if the current unit operation load is greater than or equal to a first preset load, reducing the system pressure of the air conditioner from the system pressure corresponding to the current mute gear to a conventional system pressure, wherein the first preset load is greater than the current budget load of the air conditioner.
In the above steps, the "current budget load" is an operation load that is pre-calculated by the air conditioner in the current operation environment and exactly matches the current heating/cooling demand. And the "first preset load" is a set operating load larger than the current budget load. When the current unit operation load is larger than the first preset load, the current operation load of the air conditioner is over large, the heat productivity of electronic components of the air conditioner is large, and the rotating speed of an outdoor fan needs to be increased to increase the heat exchange efficiency of the outdoor side and increase the refrigerating capacity of the air conditioner. In view of this, when the current unit operating load is greater than or equal to the first preset load, the system pressure of the air conditioner is adjusted downward from the system pressure corresponding to the current mute gear (i.e., the system pressure value in the pressure interval corresponding to the current mute gear) to the conventional system pressure, so that the air conditioner approaches the conventional system pressure to operate, exits the mute operation mode, and enters the conventional operation mode.
Further, the step of selectively correcting the system pressure of the air conditioner according to the value interval of the current unit operation load further includes:
if the current unit operation load is smaller than the first preset load and larger than the second preset load, the system pressure of the air conditioner is not adjusted, wherein,
the second preset load is less than the current budget load.
In the above step, the "second preset load" is a set operating load smaller than the current budget load. When the current unit operation load is between the first preset load and the second preset load, the current unit operation load of the surface air conditioner does not exceed the normal operation range, and the current change trend of the unit operation load is in the expected reasonable range. At this time, the system pressure value of the air conditioner is not adjusted, and the refrigeration/refrigerating effect of the air conditioner and the silencing effect are balanced.
Furthermore, the step of selectively correcting the system pressure of the air conditioner according to the value interval of the current unit operation load further includes:
and if the current unit operation load is less than or equal to a second preset load and the current mute gear has a high-level mute gear, increasing the system pressure of the air conditioner from the system pressure corresponding to the current mute gear to the preset mute pressure corresponding to the high-level mute gear.
In the above steps, the "advanced mute stage" specifically refers to a mute stage having a stronger muting effect than that of the current mute stage. For example, in a case where the mute operation mode includes a first-stage mute gear and a second-stage mute gear, if the current mute gear is the first-stage mute gear, the current mute gear has a high-stage mute gear with a stronger mute effect, that is, the second-stage mute gear. And if the current mute gear is a secondary mute gear, the current mute gear does not have a high-grade mute gear.
When the current unit operation load is less than or equal to the second preset load, the heat productivity of the electronic components of the air conditioner is small at the moment, so that the normal operation of the air conditioner is not influenced even if the refrigerating capacity of the air conditioner is reduced. At this moment, under the condition that the mute gear can be further lifted, the current system pressure of the air conditioner can be adjusted to the preset mute pressure corresponding to the high-level mute gear by reducing the rotating speed of the outdoor fan, so that the current mute operation effect of the air conditioner is further optimized, and a user obtains better noise reduction experience.
As an example, in the case where the silent operation mode includes the primary silent gear and the secondary silent gear, the first preset load may be set to be 1.2 times the current budget load, and the second preset load may be set to be 0.5 times the current budget load. Of course, in practical applications, those skilled in the art may adjust the first preset load and the second preset load according to the performance parameters of the air conditioner and the actual mute requirement. In addition, although the above-described embodiment is described in connection with two preset load parameters, the first preset coincidence and the second preset load, this is not limitative. Under the condition that the number of the mute gears is large, a person skilled in the art can set more preset loads to refine the numerical interval where the current unit operation load is located.
In a possible embodiment, in the case that the mute operation mode includes only one mute shift, the step of "selectively correcting the system pressure of the air conditioner according to the value interval of the current unit operation load" includes:
and if the current unit operation load is greater than or equal to a first preset load, the system pressure of the air conditioner is adjusted from the system pressure corresponding to the mute gear to the conventional system pressure.
Further, the step of selectively correcting the system pressure of the air conditioner according to the value interval of the current unit operation load further includes:
and if the current unit operation load is smaller than the first preset load, not adjusting the system pressure of the air conditioner.
Continuing to refer to fig. 2, fig. 2 is a flowchart illustrating the detailed steps of a preferred embodiment of the mute operation control method of the air conditioner according to the present invention. As shown in fig. 2, in a case that the mute operation mode includes a first-stage mute shift and a second-stage mute shift, when a user selects any mute shift of the air conditioner to be determined, a preferred embodiment of the mute operation control method of the air conditioner of the present invention specifically includes the following steps:
step S100: acquiring the current system pressure of the air conditioner;
step S101: judging whether the current system pressure is smaller than a preset mute pressure corresponding to the current mute gear;
if the current system pressure is smaller than the preset mute pressure corresponding to the current mute gear, executing the step S102, otherwise, executing the step S103;
step S102: reducing the rotating speed of the outdoor fan so as to adjust the current system pressure to be the preset mute pressure corresponding to the current mute gear;
step S103: maintaining the current system pressure operation of the air conditioner;
step S104: after the preset time, acquiring the current unit operation load of the air conditioner;
step S105: determining a numerical value interval where the current unit operation load Q is located;
if Q is equal to or greater than Q1, executing step S106, if Q2 < Q1, executing step S107; if Q is less than or equal to Q2, executing step S108;
step S106: the system pressure of the air conditioner is adjusted from the system pressure corresponding to the current mute gear to the conventional system pressure;
step S107: the system pressure of the air conditioner is not adjusted;
step S108: judging whether the current mute gear is a first-level mute gear, namely whether a high-level mute gear (a second-level mute gear) exists;
if the current mute gear is the first-level mute gear, executing step S109, otherwise executing step S107;
step S109: and the system pressure of the air conditioner is adjusted from the system pressure corresponding to the first-stage mute gear to the preset mute pressure corresponding to the second-stage mute gear.
It should be understood by those skilled in the art that although the mute operation control method of the present invention is illustrated only in connection with the case of one or two mute levels, this is not limitative, and in fact, those skilled in the art may modify the number of mute levels according to the dividing requirement of the mute effect, such as setting the mute levels to four.
In summary, the mute operation control method of the air conditioner of the present invention can use the preset mute pressure as a comparison standard of the real-time system pressure of the air conditioner, so as to selectively reduce the outdoor fan rotation speed of the air conditioner based on the specific difference degree between the current system pressure of the air conditioner and the preset mute pressure, thereby preventing the air conditioner from operating at a fixed large outdoor fan rotation speed during the whole course of cooling/heating, fundamentally eliminating most of the operation noise of the air conditioner, and achieving the purpose of enabling the air conditioner to operate in a mute manner. On the basis, the mute operation control method can intermittently correct the system pressure based on the unit operation load so as to simultaneously ensure the operation efficiency and the mute effect of the air conditioner and optimize the mute effect as much as possible.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments.
