Detailed Description
The following will describe embodiments of the present application in detail with reference to the drawings and examples, thereby solving the technical problems by applying technical means to the present application, and realizing the corresponding technical effects can be fully understood and implemented accordingly. The embodiment of the application and the characteristics in the embodiment can be mutually combined on the premise of no conflict, and the formed technical scheme is within the protection scope of the application.
As known from the background art, the existing solution is to use two vapor-liquid separators or a larger vapor-liquid separator to solve the bias flow problem of the compressor, resulting in increased cost. And for the compact-structure unit, another vapor-liquid separator cannot be added or a larger vapor-liquid separator cannot be replaced.
In view of the above, the present application provides a method, an apparatus, a storage medium and an electronic device for processing a bias current of a compressor, which solve the technical problem of increased cost caused by adding a vapor-liquid separator or replacing a larger vapor-liquid separator in the related art.
Example 1
Fig. 1 is a flow chart of a method for processing bias current of a compressor according to an embodiment of the present application, as shown in fig. 1, the method is applied to an air conditioning unit with dual compressors, and the method includes:
S101, judging whether a refrigerant leaving a vapor-liquid separator is in a vapor-liquid two-phase state or not;
it should be noted that, the method is applied to an air conditioning unit with two compressors, and the bias flow of the compressors will only occur if the two compressors are operated, so before executing step S101, a step may be further included: and judging whether both compressors are in an operating state.
Because the air conditioning unit generally runs only when a single compressor can meet the capacity requirement, and the single compressor cannot meet the capacity requirement, the other compressor can be run, so that whether two compressors are in the running state can be judged by detecting whether the compressors in the secondary running are in the running state, the running state of one compressor can be detected less, and the effects of improving the efficiency and saving the energy are achieved.
S102, if the refrigerant leaving the vapor-liquid separator is in a vapor-liquid two-phase state, judging whether the bias flow of the compressor occurs;
S103, if the bias flow of the compressors is judged, selecting a target compressor with bias flow in the double compressors;
S104, closing the target compressor;
It should be noted that, stopping one compressor, allowing the other compressor to operate independently consumes the liquid refrigerant in the vapor-liquid separator, and when the vapor-liquid separator is all the gaseous refrigerant, the bias flow phenomenon of the compressor will not occur. If two compressors are directly operated, bias flow can cause one compressor to have a large exhaust superheat and one compressor to have a small exhaust superheat, which is disadvantageous for both compressors.
S105, restarting the air conditioning unit when detecting that the difference value between the air outlet temperature of the vapor-liquid separator and the air inlet temperature of the vapor-liquid separator is larger than a preset temperature threshold value and the duration reaches a first preset time.
It should be noted that, when the vapor-liquid separators are all gaseous refrigerants, T Air outlet -T Low and low ＞T Pre-preparation is set, that is, the difference between the outlet temperature of the vapor-liquid separator and the inlet temperature of the vapor-liquid separator is greater than a preset temperature threshold, and in order to ensure accuracy, a first preset time is set to ensure that the vapor-liquid separators are all gaseous refrigerants.
In some embodiments, the determining whether the refrigerant leaving the vapor-liquid separator is in a vapor-liquid two-phase state includes:
If the T Air outlet -T Low and low ≤T Pre-preparation is detected continuously for the second preset time, judging that the refrigerant leaving the vapor-liquid separator is in a vapor-liquid two-phase state;
Wherein T Air outlet is the outlet temperature of the vapor-liquid separator, T Low and low is the inlet temperature of the vapor-liquid separator, and T Pre-preparation is a preset temperature threshold.
The difference between the gas outlet temperature of the gas-liquid separator and the gas inlet temperature of the gas-liquid separator when the refrigerant leaving the gas-liquid separator is in a pure gas state is different from the difference between the gas outlet temperature of the gas-liquid separator and the gas inlet temperature of the gas-liquid separator when the refrigerant leaving the gas-liquid separator is in a gas-liquid two-phase state, so that a preset temperature threshold can be set according to the difference between the gas outlet temperature of the gas-liquid separator and the gas inlet temperature of the gas-liquid separator when the refrigerant leaving the gas-liquid separator is in a pure gas state, the state of the refrigerant leaving the gas-liquid separator is judged, and when the refrigerant leaving the gas-liquid separator is in the gas-liquid two-phase state, the flow and the state of the refrigerant entering each compressor are inconsistent, and the bias flow is caused finally.
In some embodiments, the determining whether a compressor bias current is present comprises:
If the |T Top 1-T Top 2|≥T Top 0 is detected in the third preset time continuously, judging that the bias flow of the compressor occurs;
Wherein, T Top 1 is the first compressor shell top temperature, T Top 2 is the second compressor shell top temperature, and T Top 0 is a preset shell top temperature threshold.
It should be noted that, once the bias flow of the compressors occurs, the cooling effect of the two compressors is inconsistent, the inconsistent cooling effect of the two compressors can be determined by detecting the shell top temperatures of the two compressors, that is, the bias flow occurs, and the preset shell top temperature threshold is theoretically 0, when the refrigerants entering the two compressors are in pure gas state, the cooling effect of the two compressors is the same, the difference between the shell top temperature of the first compressor and the shell top temperature of the second compressor is equal to 0, but in the practical application process, a small amount of liquid refrigerant is allowed to occur, that is, the difference between the shell top temperature of the first compressor and the shell top temperature of the second compressor is allowed to be greater than 0, so that a reasonable preset shell top temperature threshold which is greater than 0, for example, 10 ℃ can be selected according to experience, and the third preset time can be preferably 20 seconds.
In some embodiments, the target compressor of the selected dual compressor for which bias current occurs comprises:
Comparing the shell top temperatures of the two compressors;
if T Top 1＞T Top 2, determining that the second compressor is biased;
If T Top 1＞T Top 2, the first compressor bias current is determined.
It should be noted that, if T Top 1＞T Top 2, it is indicated that more liquid refrigerant flows into the second compressor, so that it is determined that the second compressor is biased; if T Top 1＞T Top 2, it is indicated that more liquid refrigerant is flowing into the first compressor, and therefore, a bias flow of the first compressor is determined.
In summary, an embodiment of the present application provides a method for processing a bias current of a compressor, including: judging whether the refrigerant leaving the vapor-liquid separator is in a vapor-liquid two-phase state or not; if the refrigerant leaving the vapor-liquid separator is in a vapor-liquid two-phase state, judging whether the bias flow of the compressor occurs; if the bias flow of the compressors is judged to occur, selecting a target compressor with bias flow in the double compressors; turning off the target compressor; and restarting the air conditioning unit when detecting that the difference value between the air outlet temperature of the vapor-liquid separator and the air inlet temperature of the vapor-liquid separator is larger than a preset temperature threshold value and the duration reaches a first preset time. When the bias flow of the compressors is detected, the liquid level in the vapor-liquid separator is reduced by stopping the operation of the double compressors and only operating the single compressor, and then the air conditioning unit is restarted, so that the refrigerant can uniformly flow to the two compressors.
