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. Those skilled in the art can adapt it as desired to suit a particular application. For example, although the mute operation control method of the present invention is described in connection with an air conditioner, this is not limitative, and other heat exchange devices having similar mute operation requirements may also operate the mute operation control method of the present invention, such as a heat exchange type water heater, a heat exchange type dehumidifier, etc.
Further, it should be noted that, in the description of the present invention, although the respective steps of the control method of the present invention are described in a specific order in the present application, these orders are not limitative, 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 noise reduction effect of the existing physical noise reduction mode is not ideal and the mute operation of the air conditioner is difficult to realize, the invention provides a mute operation control method of the air conditioner, which aims to radically eliminate most of operation noise of the air conditioner and achieve the aim of enabling the air conditioner to operate in a mute mode.
In general, an air conditioner is provided with a fixed system pressure capable of satisfying the normal operation requirement of the air conditioner when the air conditioner is operated. When the air conditioner is operated, the actual system pressure is adjusted in real time by referring to the fixed system pressure so as to enable the actual system pressure to be always close to (or equal to) the fixed system pressure, thereby ensuring the normal operation of the air conditioner.
The air conditioner of the present invention includes a normal operation mode and a mute operation mode, wherein the normal operation mode is matched with a normal system pressure, which is equivalent to a fixed system pressure conventionally set by the air conditioner. The mute operation mode is matched with a preset mute pressure, which is a set pressure value greater than the normal system pressure.
Referring first to fig. 1, fig. 1 is a flowchart showing main steps of a mute operation control method of an air conditioner according to the present invention. As shown in fig. 1, the mute operation control method 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 preset mute pressure is a set critical pressure value for dividing the normal operation mode and the mute operation mode of the air conditioner. When the air conditioner is in the normal operation mode, the actual system pressure of the air conditioner is continuously adjusted towards a direction approaching the normal system pressure and is always below the critical pressure value; when the air conditioner is in the mute operation mode, the actual system pressure of the air conditioner is continuously adjusted in a direction approaching the preset mute pressure, and is always not lower than the critical pressure value.
In step S3, in view of the close relationship between the system pressure of the air conditioner and the rotational speed of the outdoor fan, the following is specific: when the rotation speed of the outdoor fan is reduced, the flow degree of the air flow at the outdoor side is reduced, and the heat exchange efficiency of the outdoor heat exchanger of the air conditioner is reduced, thereby causing a reduction in the amount of conversion (e.g., liquefaction) of the refrigerant in the outdoor heat exchanger per unit time, thereby causing an increase in the system pressure of the air conditioner. Therefore, if the value of the system pressure set by the air conditioner is larger, the rotation speed of the outdoor fan which is operated when the air conditioner approaches the system pressure is higher.
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 magnitude of the numerical difference, so that the actual system pressure of the air conditioner is not lower than the preset mute pressure and is in the range of the system pressure corresponding to the mute operation mode (namely, the system pressure is greater than or equal to the preset mute pressure), the air conditioner is in the mute operation mode, and the air conditioner is prevented from operating at a larger rotating speed of the outdoor fan to generate obvious working noise.
In the steps S1 to S3, the current system pressure of the air conditioner is compared with the preset mute pressure, so that the adjustment requirement of the rotation speed of the outdoor fan of the air conditioner can be determined, and the system pressure of the air conditioner is continuously adjusted by comparing with the preset mute pressure, so that the rotation speed of the outdoor fan of the air conditioner is always in a lower rotation range, and the purpose of enabling the air conditioner to operate in mute is achieved.
In the above embodiment, it should be noted that the conventional system pressure and the mute preset pressure are not limited, and those skilled in the art may set specific values of the conventional system pressure and the mute preset pressure according to the functional parameters of the air conditioner, the actual operation requirement of the air conditioner, and the like.
In a preferred embodiment, the mute mode of operation includes at least two mute gears, each of which is respectively matched to a predetermined mute pressure. For example, the above-mentioned mute operation mode includes a primary mute gear and a secondary mute gear having a greater mute effect than the primary mute gear, and the preset mute pressure P1 corresponding to the primary mute gear is greater than the normal system pressure P0 and less than the preset mute pressure P2 corresponding to the secondary mute gear. From the first-level silence gear to the second-level silence gear, the silence effect becomes strong. When the air conditioner is operated, a specific mute gear in a mute operation mode can be selected according to the actual mute requirement.
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 step, since the current mute gear is determined according to the current actual mute requirement of the air conditioner, such as a default mute gear set by a user or set in a mute operation mode of the system of the air conditioner, the current mute gear of the air conditioner is determined each time the mute operation is started, and thus the corresponding preset mute pressure is also determined. In this case, when the above steps are performed, only the preset mute pressure currently matched is 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 step, when the air conditioner is in any mute gear of the mute operation mode, the current actual system pressure of the air conditioner needs to be selectively adjusted compared with the preset mute pressure in the mute gear.
Taking the current mute gear as an example of the primary mute gear, when the current system pressure is smaller than the preset mute pressure P1 corresponding to the primary mute gear, the current system pressure is not in a system pressure interval [ P1, P2) corresponding to the primary mute gear, and the operation standard of the primary mute gear is not met. Therefore, the rotating speed of the outdoor fan is reduced so as to increase the current system pressure, and the current system pressure is promoted to approach the preset mute pressure P1, so that the current system pressure falls in a system pressure interval corresponding to the first-level mute gear.
Further, the step S3 further includes:
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.
In the above steps, when the current system pressure is not less than the preset mute pressure P1, the mute effect of the air conditioner during the current operation is at least not weaker than the mute effect of the one-level mute gear, so as to satisfy the mute requirement corresponding to the one-level mute gear, and therefore, the value of the current system pressure does not need to be adjusted by reducing the rotation speed of the outdoor fan.
In one possible embodiment, the mute mode of operation comprises only one mute gear, i.e. the mute mode of operation is only matched with a preset mute pressure, and the air conditioner corresponds to only one mute effect in the mute mode of operation.
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 further includes:
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 mute operation control method of an air conditioner of the present invention further includes:
after the preset time, the current unit operation load of the air conditioner is obtained;
determining a numerical interval in which the current unit operation load is located;
and selectively correcting the system pressure of the air conditioner according to the numerical interval of the current unit operation load.
In the above steps, the difference between the current unit operation effect and the actual operation requirement of the air conditioner can be determined through the numerical interval of the current unit operation load of the air conditioner. According to the difference, the system pressure of the air conditioner is corrected, so that the air conditioner can be prevented from reducing the operation effect because of pursuing the mute effect.
For example, the preset time may be set to 5 minutes.
In a preferred embodiment, the silent mode of operation is the above-described case comprising at least two silent gear steps, each of which is matched to a preset silence pressure,
the step of selectively correcting the system pressure of the air conditioner according to the 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, the system pressure of the air conditioner is downwards adjusted from the system pressure corresponding to the current mute gear to the 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 the operation load of the air conditioner, which is pre-calculated in the current operation environment and exactly matches the current heating/cooling requirement. And the "first preset load" is a set operating load greater 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 indicated to be overlarge, the heating value of electronic components of the air conditioner is larger, and the rotating speed of the outdoor fan is required to be increased to increase the heat exchange efficiency of the outdoor side and the refrigerating capacity of the air conditioner. In view of this, when the current unit operation load is greater than or equal to the first preset load, the system pressure of the air conditioner is adjusted down 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 normal system pressure, so that the air conditioner approaches the normal system pressure to operate, exits the mute operation mode and enters the normal 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 less than the first preset load and greater 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 operation load smaller than the above-described 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 refrigerating/refrigerating effect and the silencing effect of the air conditioner are balanced.
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 running load of the current unit is smaller than or equal to the second preset load and the current mute gear has the advanced mute gear, the system pressure of the air conditioner is up-regulated from the system pressure corresponding to the current mute gear to the preset mute pressure corresponding to the advanced mute gear.
In the above steps, the "advanced mute gear" specifically refers to a mute gear having a stronger mute effect than the current mute gear. For example, in the case where the mute operation mode includes a primary mute gear and a secondary mute gear, if the current mute gear is the primary mute gear, there is a higher-order mute gear, i.e., a secondary mute gear, in which the mute effect is stronger, in the current mute gear. If the current mute gear is a secondary mute gear, no advanced mute gear exists in the current mute gear.
When the running load of the current unit is smaller than or equal to the second preset load, the heat productivity of the electronic components of the air conditioner is small, so that the normal running of the air conditioner is not affected even if the refrigerating capacity of the air conditioner is reduced. At this time, 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 advanced 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 mute operation mode includes the primary mute gear and the secondary mute gear, the first preset load may be set to 1.2 times the current budget load, and the second preset load may be set to 0.5 times the current budget load. Of course, in practical applications, the person skilled in the art can adjust the magnitudes of 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 embodiment is described in connection with two preset load parameters, i.e., a first preset compliance and a second preset load, this is not a limitation. Under the condition that the number of the mute gears is large, the person skilled in the art can set more preset loads to refine the numerical interval where the running load of the current unit is located.
In one possible embodiment, in the case that the mute operation mode includes only one mute gear, the step of "selectively correcting the system pressure of the air conditioner according to the value interval in which the current unit operation load is located" includes:
and if the current unit operation load is greater than or equal to the first preset load, the system pressure of the air conditioner is downwards regulated 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:
if the current unit operation load is smaller than the first preset load, the system pressure of the air conditioner is not adjusted.
With continued reference to fig. 2, fig. 2 is a detailed step flow diagram of a preferred embodiment of a mute operation control method of an air conditioner according to the present invention. As shown in fig. 2, in the case where the mute operation mode includes a primary mute gear and a secondary mute gear, when a user selects any one of the mute gear determinations of the air conditioner, a preferred embodiment of the mute operation control method of the air conditioner of the present invention specifically includes the steps of:
step S100: acquiring the current system pressure of the air conditioner;
step S101: judging whether the current system pressure is smaller than the preset mute pressure corresponding to the current mute gear or not;
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 a preset mute pressure corresponding to the current mute gear;
step S103: enabling the air conditioner to maintain the current system pressure to operate;
step S104: after the preset time, the current unit operation load of the air conditioner is obtained;
step S105: determining a numerical interval in which the current unit operation load Q is located;
if Q is greater than or equal to Q1, executing step S106, and if Q2 is less than 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 downwards adjusted to the conventional system pressure from the system pressure corresponding to the current mute gear;
step S107: the system pressure of the air conditioner is not adjusted;
step S108: judging whether the current mute gear is a primary mute gear or not, namely whether a high-level mute gear (a secondary mute gear) exists or not;
if the current mute gear is the primary mute gear, executing the step S109, otherwise executing the step S107;
step S109: and (3) up-regulating the system pressure of the air conditioner from the system pressure corresponding to the primary mute gear to the preset mute pressure corresponding to the secondary 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 with respect to the case of only one or two mute gears, this is not limitative, but in practice, those skilled in the art may modify the number of mute gears according to the dividing requirement of the mute effect, such as setting the mute gears to four.
In summary, the mute operation control method of the air conditioner of the invention can take the preset mute pressure as the comparison standard of the real-time system pressure of the air conditioner, so as to selectively reduce the rotation speed of the outdoor fan of the air conditioner based on the specific difference degree of the current system pressure and the preset mute pressure of the air conditioner, thereby avoiding the air conditioner from running at a fixed large rotation speed of the outdoor fan in the whole process of cooling/heating, radically eliminating most of operation noise of the air conditioner and achieving the purpose of mute operation of the air conditioner. On the basis, the mute operation control method can also intermittently correct the system pressure based on the unit operation load so as to ensure the operation efficiency and the mute effect of the air conditioner at the same time and optimize the mute effect as much as possible.
