Poor allowed band, then illustrate that the operating status of air-conditioning the machine is in improper or non-optimal conditions, and after-sale service system can be with
The order of severity of abnormal running is analyzed according to the size of error, implements different after-sale services for different degree.
Unit current operating parameter and the multilevel iudge of multimachine Mean Parameters are currently run as a result, it is possible to characterize air-conditioning the machine
State, if multilevel iudge the result shows that current operating parameter and multimachine Mean Parameters in allowable range of error, characterization is empty
Adjust the machine current operating conditions normal, if multilevel iudge is the result shows that current operating parameter is permitted with multimachine Mean Parameters beyond error
Perhaps scope, then illustrate that the operating status of air-conditioning the machine is in improper or non-optimal conditions, after-sale service system can basis
The order of severity of the size analysis abnormal running of error, implements different after-sale services for different degree.
The historical data trend analysis judgment models of unit operation parameter, refering to what is shown in Fig. 2, being put down for air-conditioning the machine multicycle
The one embodiment for the trend curve analysis that equal operating parameter is formed on a timeline；Table is come with the historical operating parameter of electric current I
Levy the situation of refrigerant leakage.It is assumed that a cycle is 5 working days, then on 50 workaday time shafts, 10 cycles
Average operating parameter, or 50 workaday historical operating parameters form trend curve on a timeline, then from curve
Change can be inferred that the state of air-conditioning the machine operation, if curve conversion is gentle, either be all located at average operating parameter or more
When below machine average, illustrate air-conditioning the machine normal operation, if the trend for significantly decaying or increasing is presented in curve conversion,
Illustrate the operation of air-conditioning the machine there are potential problems, namely there is the trend and possibility to break down.
The method of above-mentioned judgment models statement can be combined with each other according to actual conditions in a particular application, or do details
Increase and decrease in judgement, but do not depart from the thought of the embodiment of the present application proposition.
When after-sale service system judges that the operating status of air-conditioning is abnormal according to the data and judgment models of acquisition,
After-sale service can be arranged to be safeguarded to customer to air-conditioning in time, ensure that air-conditioning operates in optimal or normal operation all the time
