It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Thus, a feature indicated in this specification will serve to explain one of the features of one embodiment of the invention, and does not imply that every embodiment of the invention must have the stated feature. Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.
The principles of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.
After the unit of the air conditioner is installed at a specific position of a building by an installer or a debugger, the debugger needs to start the air conditioner and inputs corresponding unit installation information according to the on-site installation condition of the air conditioner unit, so that the air conditioner can automatically complete the self-adaptive debugging process.
In this embodiment, the debugger that is operated on site by the debugger is improved, so that the debugger can receive the installation information of the unit input by the debugger on the installation site according to the field installation condition of the unit, and the installation information of the unit that can be input includes, but is not limited to, one or a combination of the connection length of the pipeline of the air conditioner, the height drop of the installation positions of the internal unit and the external unit, and the height drop of the installation positions of the internal unit and the internal unit.
The air conditioner can be adaptively debugged after being started for the first time, and relevant information of the air conditioner is collected by an external unit, wherein the relevant information includes but is not limited to: the type of the unit, the number of the connected internal and external units of the unit, various temperature and pressure parameters of the unit and the like. The judgment of what kind of debugging is required will be automatically started according to the collected information about the air conditioner, and generally, the following debugging situations can be roughly classified according to the collected information.
Referring to fig. 1, after the air conditioning unit is powered on, when the air conditioner is identified as an air conditioner with a refrigerating capacity smaller than a preset refrigerating capacity a, the simple debugging is automatically performed, the simple debugging specifically comprises two parts, one part is that a debugging worker judges whether the total number of the indoor unit and the outdoor unit of the air conditioner is consistent with the total number of the indoor unit and the outdoor unit of an installation site according to the total number of the indoor unit and the outdoor unit of the air conditioner in the information collected by the air conditioner, and the other part is that whether each component of the air conditioner can normally operate is determined, namely, after the components of the air conditioner are subjected to conventional health detection, the debugging is automatically completed.
Referring to fig. 2, after the air conditioning unit is powered on, although the air conditioner is identified as an air conditioner with a cooling capacity greater than a preset cooling capacity a, when the total number of all online indoor and outdoor units collected by the air conditioner is less than or equal to a preset number B, the air conditioner can automatically perform simple debugging, and a debugger determines whether the total number of the indoor and outdoor units of the air conditioner is consistent with the total number of the indoor and outdoor units in an installation site according to the total number of the indoor and outdoor units of the air conditioner in information collected by the air conditioner, and determines whether each component of the air conditioner can normally operate.
Referring to fig. 3, after the air conditioning unit is powered on, when the air conditioner is identified as an air conditioner with a cooling capacity greater than a preset cooling capacity and the total number of all the collected online internal and external machines is greater than a preset number, the deep debugging is automatically started.
The method comprises the steps of firstly, judging whether the total number of the air conditioner internal and external units is consistent with that of the air conditioner internal and external units in a field according to the total number of the air conditioner internal and external units in information collected by the air conditioner, determining whether each component of the air conditioner can normally operate, and then further detecting engineering installation parameters and system parameters.
The method comprises the steps that a correction coefficient of a target suction pressure of an air conditioner compressor is determined according to the pipeline connection length of the air conditioner, whether the connection length of a pipeline of the air conditioner, which is obtained by a debugging worker in an installation site and input into a debugger, is larger than or equal to a preset length or not is judged, if the connection length of the pipeline of the air conditioner is smaller than the preset length, the target suction pressure of the compressor does not need to be corrected, and if the connection length of the pipeline of the air conditioner is larger than or equal to the preset length, the target suction. When the specific correction is carried out, the target suction pressure of the compressor is set firstly, the refrigerating capacity of the internal machines is controlled to be started to be larger than the preset percentage (if the starting refrigerating capacity is larger than 80%), after the unit runs for the first preset time, the pipe inlet temperature of all the started internal machines is detected, the average value of all the pipe inlet temperatures is obtained, the temperature difference between the average value of the pipe inlet temperatures and the saturation temperature corresponding to the suction pressure of the compressor is calculated, the correction coefficient of the target suction pressure of the compressor is obtained according to the temperature difference, the suction pressure of the compressor is corrected, and the running capacity of the unit can be adjusted according to the corrected suction pressure value of the compressor.
When the connection length of the air conditioning pipeline is greater than or equal to the preset length, the values of the pipe inlet temperatures of all the started indoor units and the saturation temperature corresponding to the suction pressure of the compressor are continuously detected, and a temperature difference delta P1= the average value of the pipe inlet temperatures of all the started indoor units- [ average low pressure Ps-a ], wherein the average low pressure Ps-a is the saturation temperature corresponding to the suction pressure of the compressor.
When the temperature difference delta P1 is less than or equal to a first preset temperature difference X: the correction factor is 0.
When the temperature difference delta P1 meets a first preset temperature difference X < [ delta P1 ] and is not more than a second preset temperature difference Y: and the correction coefficient is judged and corrected by combining the proportion delta P2 of the refrigerating capacities of all the startup internal machines, and the proportion = the refrigerating capacity of the startup internal machines/the refrigerating capacity of the external machines. Taking the unit cooling operation as an example, when the ratio Δ P2 exceeds the first ratio (e.g., 80%), the correction coefficient-1 is output, and when the ratio Δ P2 is smaller than the first ratio (80%), the correction coefficient 0 is output. Taking the unit heating operation as an example: when the ratio Δ P2 is smaller than a first ratio (e.g., 80%), outputting a correction coefficient of 1; when the ratio Δ P2 is smaller than the first ratio (e.g., 80%), the correction coefficient 0 is output.
When the temperature difference satisfies the following conditions that the temperature difference is delta P1> a second preset temperature difference Y: and the correction coefficient is judged and corrected by combining with the ratio delta P2 of the refrigerating capacity of the starting internal machine of the system, and the ratio = refrigerating capacity of the starting internal machine/refrigerating capacity of the external machine. Taking the unit refrigeration operation as an example: when the proportion Δ P2 exceeds a first proportion (e.g., 80%), a correction factor of-2 is output. When the ratio Δ P2 is smaller than the first ratio (e.g., 80%), the correction coefficient-1 is output. Taking the unit heating operation as an example: when the proportion Δ P2 exceeds a first proportion (e.g., 80%), outputting a correction factor of 2; when the ratio Δ P2 is smaller than the first ratio (e.g., 80%), the correction coefficient 1 is output.
After the correction coefficient is obtained, the original suction pressure value is corrected by adding the corresponding correction coefficient.
The preset control strategy is selected according to the height difference of the installation positions between the outer machine and the inner machine and between the inner machine and the inner machine, a plurality of control strategies are preset, the control strategies are related to the flow speed and the flow of the refrigerant, if debugging personnel do not input any height difference or the input height difference is 0, the debugging personnel do not need to determine any control strategy through debugging, if the height difference exists between the outer machine and the inner machine or between the inner machine and the inner machine, the preset control strategy is selected or switched to carry out debugging until the flow speed or the flow of the refrigerant meets the preset requirement, the air conditioner records the selected control strategy to control the opening degree of an electronic expansion valve of the unit, so that the flow speed of the refrigerant is adjusted, and the working capacity of the multi-split air conditioner is controlled.
The refrigerant condition of the unit is obtained according to the running condition of the air conditioner so as to detect whether a refrigerating system of the air conditioner is a supercooling medium or a refrigerant lack. According to the working condition that the unit of the air conditioner corresponds to the outdoor environment temperature (the refrigerant lack detection is the detection during the shutdown, so the working condition is the current outdoor environment temperature condition during the shutdown), whether the detected exhaust pressure of the compressor is less than or equal to the preset pressure is judged, if so, the refrigerant condition of the unit is judged to be the refrigerant lack, and a debugging person needs to be informed to carry out corresponding processing. Starting a unit of an air conditioner, detecting the exhaust superheat degree of the unit after the unit operates for more than a second preset time (for example, after the unit operates for 10 min), wherein the exhaust superheat degree refers to a difference value between the exhaust temperature of an operating compressor and the temperature corresponding to the exhaust pressure of a system compressor, namely [ exhaust superheat degree actual value ] = [ compressor exhaust temperature ] - [ exhaust pressure Pd ], the exhaust pressure Pd is the temperature corresponding to the exhaust pressure, and if the compressor is a plurality of compressors, the lowest exhaust pressure temperature value of the operating compressor is taken. And when the exhaust superheat degree of the unit is smaller than a first preset exhaust superheat degree, judging that the refrigerant condition of the unit is a supercooling medium running condition. One or both of these options may be selected by one skilled in the art depending on the circumstances.
The health condition of the oil return pipe of the compressor is obtained according to the running condition of the air conditioner and is used for detecting whether the oil return pipe is blocked or leaked. And starting a unit of the air conditioner, detecting the exhaust superheat degree of the unit after the unit operates for more than a third preset time (for example, the unit operates for more than 20 min), and judging that the oil return pipe of the compressor is blocked when the exhaust superheat degree of the unit is more than a second preset superheat degree and the temperature of the oil return pipe of the compressor is less than the saturation temperature corresponding to the exhaust pressure or the temperature of the oil return pipe of the compressor is less than the current outdoor environment temperature. And stopping the operation of the compressor, detecting the temperature of the oil return pipe after the stand-by of the unit exceeds a fourth preset time (for example, the stand-by lasts for more than 2 hours), and judging that the oil return pipeline has leakage when the temperature of the oil return pipe is higher than the saturation temperature corresponding to the exhaust pressure of the compressor or the temperature of the oil return pipe is higher than the current outdoor environment temperature. One or both of these options may be selected by one skilled in the art depending on the circumstances.
In the debugging process, the unit needs to be bound with the GPRS module for data collection, after the unit enters the debugging process, the air conditioning unit detects whether the GPRS module is on line, if not, the unit does not enter the adaptive debugging process, if so, the adaptive debugging process is started, and the execution condition and the debugging data of the debugging process can be completely collected in the whole debugging process.
Meanwhile, the air conditioner can also position the specific installation geographical position of the unit according to the GRPS module, confirm the altitude and climate area of unit installation, and correct the unit output capacity according to the atmospheric pressure of different altitudes or different climate areas. The unit leaves factory and sets up a plurality of climatic regions or interval of atmospheric pressure, different climatic regions or interval of atmospheric pressure set up different output ability correction factor, the output used for correcting ability, after the unit is installed, the climatic information that GPRS transmits, carry on the adaptive positioning to the area that the unit sets up. For example, a person skilled in the art can correspond to a pre-divided climate altitude area according to the location information located by the GPRS module: the number of the regions is not limited to 5, different correction coefficients are set in different regions, and after the unit is powered on to acquire the geographic position information positioned by the GPRS module, the corresponding correction coefficients are selected to be added with the actual output capacity to correct the output capacity.
When the device is applied specifically, for example, a certain shop needs to be provided with a shop multi-split air conditioner, the installation project only needs 1 to drag 2 units, and the installation connecting pipe connecting line, the refrigerant quantity and the like are controllable aiming at the installation project, so that the total quantity of the internal and external machines and the communication between the internal and external machines can be confirmed to be normal, and the debugging can be completed. For example, a hotel needs to install multi-split air conditioners, the number of the multi-split air conditioners in the system is hundreds, and therefore for the installation project, after the unit is debugged, whether the total number of the connection of the internal unit and the external unit of the unit is the same as the actual number, whether each component of the unit is normal, whether system parameters are abnormal, whether a refrigerant is appropriate, whether a pipeline is blocked, whether the state of a valve is judged, and the trial operation and starting are confirmed. And adjusting corresponding control parameters according to the installation information of the project, and changing a control strategy according to the positioning information and the climate parameters so that the multi-split air conditioner can have the optimal parameter range of the specific installation position.
