Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Fig. 1 is a flowchart of an embodiment of a method for controlling an outdoor air conditioner fan according to the present invention, and as shown in fig. 1, the method for controlling an outdoor air conditioner fan according to the present embodiment may specifically include the following steps:
100. acquiring operation information of the multi-split system;
for example, the operation information of the multi-split air conditioning system in the embodiment may include, but is not limited to, an operation frequency of the compressor and an external ambient temperature of the outdoor unit. Therefore, in the embodiment, the operating frequency of the compressor can be obtained according to the capacity requirement of the indoor unit, and the external environment temperature of the outdoor unit is obtained through a dry bulb thermometer in the outdoor unit.
101. Determining a temperature value corresponding to the target high pressure of the multi-split system according to the operation information of the multi-split system;
in a specific implementation process, after the operation information of the multi-split air conditioning system is obtained, a temperature value corresponding to a target high pressure of the multi-split air conditioning system may be determined according to a preset analysis rule, an operation frequency of a compressor in the operation information of the multi-split air conditioning system, and an external environment temperature of an outdoor unit in the operation information of the multi-split air conditioning system. The temperature value corresponding to the target high pressure of the multi-split air conditioning system is preferably an allowance range value.
For example, the analysis rule preset in this embodiment can be implemented by using the following calculation formula (1):
T1＝(A×F+T2+B)±C (1)
wherein, T1 is a temperature value corresponding to a target high pressure of the multi-split air conditioning system, a is a constant, F is an operation frequency of the compressor, T2 is an external environment temperature of the outdoor unit, and C is an allowable error.
After the operating frequency of the compressor and the external environment temperature of the outdoor unit are obtained, the operating frequency of the compressor and the external environment temperature of the outdoor unit can be substituted into the calculation formula (1), so that a temperature value corresponding to the target high pressure of the multi-split system can be obtained.
In this embodiment, the temperature value corresponding to the target high pressure of the multi-split air-conditioning system is preferably an allowance range value obtained according to the operating frequency of the compressor and the external environment temperature of the outdoor unit, and the range is relatively small and real-time, so that when the pressure of the multi-split air-conditioning system is controlled, the precision is high, and the subsequent adjustment of the operating frequency of the outdoor fan of the air-conditioning system is facilitated.
102. And adjusting the operating frequency of the outdoor fan of the air conditioner according to the temperature value corresponding to the target high pressure of the multi-split system.
After the temperature value corresponding to the target high pressure of the multi-split air-conditioning system is obtained, the operating frequency of the outdoor fan of the air-conditioning can be adjusted according to the temperature value corresponding to the target high pressure, so that the pressure of the high-pressure side of the multi-split air-conditioning system is controlled within the temperature value corresponding to the target high pressure. For example, after the temperature value of the current high pressure of the multi-split system is obtained, if the detected temperature value of the current high pressure is smaller than the temperature value corresponding to the target high pressure, the operating frequency of the outdoor fan of the air conditioner is reduced; and if the detected temperature value of the current high pressure is larger than the temperature value corresponding to the target high pressure, the operating frequency of the outdoor fan of the air conditioner is increased.
In the embodiment, the temperature value corresponding to the target high pressure has higher precision, so that the operation frequency of the outdoor fan of the air conditioner can be more reasonable when the operation frequency of the outdoor fan of the air conditioner is adjusted, the multi-split system can operate under a better high pressure value, and the energy consumption of the multi-split system is reduced.
For example, in the high-voltage control method in the prior art, if the temperature value corresponding to the target high voltage is 30 to 40 ℃, when the external environment temperature of the outdoor unit is 45 ℃, because the load is large, a high temperature value is required for the multi-split air conditioner system to ensure comfort and relatively high energy consumption, and because the temperature value corresponding to the target high voltage is set to be 30 to 40 ℃, when the temperature of the high-voltage side of the multi-split air conditioner system is higher than 40 ℃, the operating frequency of the outdoor fan of the air conditioner is adjusted, so that the temperature of the high-voltage side of the multi-split air conditioner system is reduced to 40 ℃, that is, the pressure of the high-voltage side of the multi-split air conditioner system cannot reach 45 ℃, the comfort of the use of the air conditioner cannot be ensured, and the energy consumption is high in the operation process of the multi-.
In addition, in this embodiment, because the temperature value corresponding to the target high voltage of the multi-split air-conditioning system is preferably an allowance range value, it can effectively avoid the frequent switching frequency of the outdoor fan of the air-conditioning, reduce the failure rate of the outdoor fan of the air-conditioning, and improve the service life of the outdoor fan of the air-conditioning.
In the embodiment, the temperature value corresponding to the target high pressure of the multi-split air-conditioning system is a relatively accurate range value determined according to the operation information of the multi-split air-conditioning system, such as the operation frequency of the compressor, the external environment temperature of the outdoor unit and the like, and can be changed in real time according to the operation information of the multi-split air-conditioning system, so that the temperature value corresponding to the target high pressure with a smaller range can be obtained when the air-conditioning works under any condition, the comfort of the air-conditioning is ensured, and the energy consumption of the multi-split air-conditioning system in the operation process is reduced.
Similarly, for the shutdown condition of the air conditioner at the temperature close to the temperature point, the control principle is the same as that of the shutdown condition at the high temperature, and the above related description is referred to for details, which is not repeated herein.
The main executing body of the control method of the air conditioner outdoor fan in this embodiment may be a control device of the air conditioner outdoor fan, and the control device of the air conditioner outdoor fan may be specifically integrated by software, which is not particularly limited in this embodiment.
According to the control method of the air conditioner outdoor fan, the operation information of the multi-split air conditioner system is obtained; determining a temperature value corresponding to the target high pressure of the multi-split system according to the operation information of the multi-split system; the operating frequency of the outdoor fan of the air conditioner is adjusted according to the temperature value corresponding to the target high pressure of the multi-split air conditioner system, the high-pressure range value of the multi-split air conditioner system is adjusted in real time, the range is small, the pressure control precision of the multi-split air conditioner system is high, and the operating frequency of the outdoor fan of the air conditioner is adjusted more reasonably. By adopting the technical scheme of the invention, the energy consumption of the multi-split system can be reduced.
In a specific implementation process, if the high voltage of the multi-split air conditioner system is too high, the energy consumption and the reliability of the multi-split air conditioner system are not good, and the hidden danger of triggering the high voltage protection of the multi-split air conditioner system exists.
For example, the first preset temperature value may be 40 ℃, the saturation temperature corresponding to the first fixed temperature value is 50 ℃ ± 0.5 ℃, and if the external environment temperature of the outdoor unit is 50 ℃, although the calculation formula (1) is used to obtain the better temperature value corresponding to the target high voltage, the temperature value exceeds the high voltage protection value, so that the temperature value corresponding to the target high voltage of the multi-split air-conditioning system may be set to a value corresponding to 50 ℃ ± 0.5 ℃.
Similarly, when the high voltage of the multi-split air conditioner system is too low, the high voltage is unfavorable for the energy consumption and the reliability of the system, and the hidden danger of triggering the low voltage protection of the system exists, so in the above embodiment, when the temperature value corresponding to the target high voltage of the multi-split air conditioner system is determined, the temperature value cannot be too low, and in the actual application process, if the external environment temperature of the outdoor unit is detected to be less than the second preset temperature value, the temperature value corresponding to the target high voltage is set as the second fixed temperature value; the first preset temperature value is larger than the second preset temperature value. For example, the second preset temperature value is 25 ℃, and the second fixed temperature value is a value corresponding to 31 ℃ ± 0.5 ℃.
In a specific implementation process, if it is detected that the external environment temperature of the outdoor unit is greater than or equal to the second preset temperature value and the external environment temperature of the outdoor unit is less than or equal to the first preset temperature value, a corresponding temperature value corresponding to a target high voltage may be obtained by using the calculation formula (1), but when the frequency of the compressor is too high, the obtained temperature value corresponding to the target high voltage may still exceed the high voltage protection value, so in this embodiment, if it is detected that the operating frequency of the compressor is less than or equal to the preset frequency value, the operating frequency of the compressor is used as a variable parameter, and the temperature value corresponding to the target high voltage is obtained according to the preset first calculation formula, the operating frequency of the compressor, and the external environment temperature of the outdoor unit; or if the operating frequency of the compressor is detected to be less than or equal to the preset frequency value, setting the operating frequency of the compressor as a constant, and obtaining a temperature value corresponding to the target high pressure according to a preset second calculation formula and the external environment temperature of the outdoor unit. Wherein the first calculation formula is a calculation formula (1), and the second calculation formula can be realized by using the following calculation formula (2):
T1＝(D+T2)±C (2)
wherein D is A × F1+ B, f1 is a constant.
According to the control method of the air-conditioning outdoor fan, through calculation and experiments, when the operating frequency of the air-conditioning outdoor fan is adjusted according to the temperature value corresponding to the target high voltage of the multi-split air-conditioning system, at least five frequency points of the air-conditioning outdoor fan can operate, the operable range of the air-conditioning outdoor fan is wide enough, the problem of short service life caused by frequent switching of the operating frequency is avoided to a great extent, and meanwhile, the fault rate of the air-conditioning outdoor fan can be reduced.
For example, within the tolerance range, the air conditioner outdoor fan has five frequency points which can be operated. For example, the saturation temperature corresponding to the high voltage is controlled to be 30 +/-1 ℃, namely controlled to be 29-31 ℃, in the range, the air-conditioning outdoor fan has at least five frequency points of 20Hz, 21Hz, 22Hz, 23Hz and 24Hz and can operate, namely when the temperature value corresponding to the target high voltage of the multi-split air-conditioning system is determined to be 29-31 ℃, the air-conditioning outdoor fan only needs to operate at any frequency of 20 Hz-24 Hz, and therefore frequent switching of the operating frequency of the air-conditioning outdoor fan is avoided.
Fig. 2 is an experimental diagram of a control method of an outdoor fan of an air conditioner according to the present invention, and as shown in fig. 2, in this embodiment, a straight line 1 is a linear graph of frequency versus high pressure when an external ambient temperature of an outdoor unit is 30 ℃ and a compressor is a single cylinder under an ideal condition, a curve 4 is a graph of frequency versus high pressure when the external ambient temperature of the outdoor unit is 30 ℃ and the compressor is a single cylinder during an actual operation process, and a curve 5 is a graph of frequency versus high pressure when the external ambient temperature of the outdoor unit is 30 ℃ and the compressor is a double cylinder during an actual operation process. In the theoretical case of the straight line 2, the external environment temperature of the outdoor unit is 35 ℃, the frequency-high pressure linear graph is obtained when the compressor is a single cylinder, the curve 6 is the frequency-high pressure curve graph when the external environment temperature of the outdoor unit is 35 ℃ and the compressor is a single cylinder in the actual operation process, and the curve 7 is the frequency-high pressure curve graph when the external environment temperature of the outdoor unit is 35 ℃ and the compressor is a double cylinder in the actual operation process. In the theoretical case of the straight line 3, the external environment temperature of the outdoor unit is 40 ℃, the frequency-high pressure linear graph is obtained when the compressor is a single cylinder, the curve 8 is the frequency-high pressure curve graph when the external environment temperature of the outdoor unit is 40 ℃ and the compressor is a single cylinder in the actual operation process, and the curve 9 is the frequency-high pressure curve graph when the external environment temperature of the outdoor unit is 40 ℃ and the compressor is a double cylinder in the actual operation process.
As can be seen from fig. 2, in this embodiment, a frequency-high voltage curve graph in actual operation of the multi-split air-conditioning system is substantially consistent with a frequency-high voltage linear graph in a theoretical situation, which illustrates that the control method of the air-conditioning outdoor fan according to this embodiment can reasonably adjust the operation frequency of the air-conditioning outdoor fan, and can reduce energy consumption of the multi-split air-conditioning system.
