The inverter air conditioner refers to the conventional air conditioner of the inverter.The compressor is the heart of the air conditioner, and its speed directly affects the use efficiency of the air conditioner. The inverter is the control system used to control and adjust the speed of the compressor to make it always in a state of speed.Energy -saving at least 30%).
Inverter air conditioning classification
The variable frequency air conditioner can be roughly divided into: AC variable frequency and DC frequency conversion.AC frequency frequency air conditioners use AC frequency conversion compressors, which adjusts the voltage conversion twice. Because of the fixed -frequency compressor, there is no startup capacitor, so the circuit loss is reduced, thereby achieving the purpose of power saving.
AC frequency frequency
Adopt AC frequency conversion compressors and adjust the voltage conversion twice to achieve the purpose of power saving.
DC inverter
Using DC digital variable speed compressor, only one voltage conversion, similar to the DC motor, removes the iron loss in the circuit. ThereforeEssence
Analysis of inverter air conditioning maintenance skills
Most of the time in the low -speed operating state, the variable frequency air conditioner compressor will not start frequently, so it is not easy to break.The faults generally occur in the control circuit, and there are components such as thyristor, transistors, resistors, capacitors, and integrated circuits with high failure incidence.Because there are many control circuit components and will be related to each other. Once a failure is faulty, it is difficult to repair.Therefore, pay attention to the following points during maintenance.
1. If the cause of failure is not checked and forcibly operates, the circuit will create a circuit over voltage or over -current, which will damage some normal components.
2. Four insurance tubes are commonly used in variable frequency air conditioners, which are installed on the inner room control board, outdoor control board, power board, main power supply circuit.Insurance tubes are often caused by short circuits in the corresponding circuit analysis or circuit.If only the insurance tube is replaced without finding the cause of the fault, it is likely that the components are damaged due to excessive pressure.
3. Inverter air conditioners usually have only 2 to 3 start capacitors, and the capacity is between 480 and 2000UF, such as capacitors breakdown, disconnection, or parameter changes, power circuits, and flow.The machine cannot start normally.
4. Maintaining frequency frequency air conditioners, first clarify the principle of the circuit working principle and the normal parameters of each component. It is best to write down the normal working data of the key components. After the failure, it can be measured and compared.exclude.
