Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for conditioning an air conditioner, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system, such as a set of computer executable instructions, and that although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that illustrated herein.
Fig. 1 is a flowchart of a method for adjusting an air conditioner according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, detecting whether the air conditioner generates exhaust fluctuation in the low-frequency operation process, wherein the exhaust fluctuation is the fluctuation caused by the incoordination between the exhaust temperature response speed of a compressor of the air conditioner and the opening change speed of an expansion valve;

step S106, adjusting the action time of the expansion valve according to the response lag time.
In the embodiment of the invention, whether the air conditioner generates exhaust fluctuation in the low-frequency operation process is detected, wherein the exhaust fluctuation is the fluctuation caused by the incoordination between the exhaust temperature response speed of a compressor of the air conditioner and the opening change speed of an expansion valve; acquiring a response delay time length when the exhaust fluctuation is generated, wherein the response delay time length is a time length required for controlling the coordinated change of the exhaust temperature response speed when the opening change speed is changed in a stable state; the action time of the expansion valve is adjusted according to the response lag time, so that the purpose of adjusting the action time of the expansion valve according to the reason of the exhaust fluctuation generated in the low-frequency operation process of the air conditioner is achieved, the technical effect of avoiding the adverse effect caused by the exhaust fluctuation generated in the low-frequency operation process of the air conditioner is achieved, and the technical problems that the main reason of the exhaust fluctuation is not clear and the corresponding solving measure is not provided in the related technology are solved.
Optionally, the exhaust fluctuation is a fluctuation caused by an inconsistency between an exhaust temperature response speed of a compressor of the air conditioner and an opening degree change speed of an expansion valve.
Since one of the root causes of the above-mentioned exhaust fluctuation is the inconsistency between the exhaust temperature response speed of the compressor and the opening degree change speed of the expansion valve, it is necessary to adjust the actuation time of the above-mentioned expansion valve, that is, the dynamically adjustable valve opening degree change speed, to be compatible with the fixed exhaust temperature response speed of the air conditioning system, and thus it is necessary to determine the response delay time period of the air conditioning system.

It should be noted that the response lag time T is described aboveLMay be understood as the period of time required for a system parameter (e.g., an exhaust parameter) to vary by a unit amount when a control parameter of the air conditioning system is changed in a steady state; because the expansion valve mostly adopts an interval table control method, the response lag time is the time required for controlling the coordinated change of the response speed of the exhaust temperature when the opening change speed changes in a stable state.
As an alternative embodiment, the above-mentioned influence factor of the response delay time includes but is not limited to at least one of the following: it should be noted that, the frequency of the compressor, the heat exchange rate of the heat exchanger (for example, the rotation speed of the inner fan, the rotation speed of the outer fan, the inner ring, and the outer ring), the amount of refrigerant, the volume of the refrigerant channel, the heat capacity of the material, and the like may be determined by a test method because the influence factors are basically impossible to obtain through theoretical calculation.

step S202, acquiring a first response time of the air conditioner under a first operation condition, wherein the first operation condition is that the air conditioner is operated by adopting a lowest compressor frequency value and a lowest fan rotating speed value;
step S204, acquiring a second response time of the air conditioner under a second operation condition, wherein the second operation condition is that the air conditioner operates by adopting a highest compressor frequency value and a highest fan rotating speed value;

T used in actual control methodLThe first test is carried out under the conditions of lower limit of normal working condition, lower limit of frequency and lowest rotating speed of a fanA response time period TLmaxTesting under the conditions of upper limit of normal working condition, upper limit of frequency and highest rotating speed of fan to obtain second response time TLminThen by TLmaxAnd TLminObtaining T for baseline interpolationLThe value is obtained.
Optionally, the first response duration and the second response duration are both based on a linear interpolation, and as an optional embodiment, multiple test experiments may be performed in this embodiment, and then several more reference response duration values may be taken to improve the accuracy.
In an alternative embodiment, the response delay time T is calculated by the following calculation formulaL：
Wherein, TLmaxFor the first response time, TLminFor said second response period, f is the standard compressor frequency value, f1For the compressor frequency value in the first operating condition, f2Is the compressor frequency value, r, for the second operating conditionnIs a standard evaporation side fan rotating speed value rwIs a standard fan rotating speed value of a condensation side, rn1The rotation speed value r of the fan at the evaporation side under the first operation conditionn2The rotation speed value r of the evaporation side fan under the second operation conditionw1Is the rotational speed value r of the fan at the condensation side under the first operation conditionw2The rotation speed value of the condensing side fan under the second operation condition is obtained.
In an alternative embodiment, adjusting the actuation time of the expansion valve in accordance with the response lag time comprises: obtaining an adjustment interval of the expansion valve, wherein the adjustment interval includes: a rapid regulation interval and a normal regulation interval; and adjusting the action time of the normal adjustment interval according to the response lag time.
In an alternative embodiment, the following calculation is used to adjust the normal tone according to the response delay periodOperation time T between sectionsv：Tv＝α×TL；
Wherein α is a margin coefficient of the normal regulation interval.
In the embodiment of the present application, the operation section of the rapid adjustment section is not adjusted or corrected.
In an optional embodiment, the method further includes:
step S302, increasing the current compressor frequency value of the air conditioner to an oil return frequency value;
and step S304, reducing the oil return frequency value to a target compressor frequency value required by the low-frequency operation process by adopting different frequency reduction rates and step reduction modes, wherein the frequency reduction rate of the oil return frequency value is smaller than a preset frequency reduction rate limit value under the condition that the oil return frequency value is smaller than a critical frequency value.
In the embodiment of the present application, in order to avoid the exhaust fluctuation caused by the gas leakage of the high-low pressure chamber of the compressor during the test or the low-frequency operation after the air conditioner is started, the current compressor frequency value of the air conditioner may be controlled to be reduced to the target compressor frequency value required by the low-frequency operation process according to, but not limited to, the following methods: raising the current compressor frequency value of the air conditioner to an oil return frequency value f3(ii) a Reducing the oil return frequency value to a target compressor frequency value required by the low-frequency operation process by adopting different frequency reduction rates and stepped reduction modes, for example, as shown in fig. 3, from f3Down to f at a down rate of A1 from f4Down to f5The down-conversion rate of time is a 2.
And under the condition that the oil return frequency value is smaller than a critical frequency value, the frequency reduction rate of the oil return frequency value is smaller than a preset frequency reduction rate limit value, wherein the critical frequency value is the highest frequency value of the running of the compressor of the air conditioner when the high-pressure chamber and the low-pressure chamber leak gas.
As another optional embodiment, besides the test method for determining the response delay time, the air conditioning system can be used for automatically operating according to the method for determining the response delay time, so that the development investment is reduced, and the difference adaptability of individual prototypes is improved.
