The fixed capacitor and variable capacitor air conditioners are connected in different ways.
For a fixed capacitance air conditioner, the capacitor needs to be connected between the two terminals of the motor, and the capacitor is connected in parallel.
This can help stabilize the current and voltage, thereby increasing the air conditioning efficiency and power factor.
Therefore, during installation, the capacitor should be fixed on the motor to prevent vibration and heat damage.
For variable capacitance air conditioners, capacitors are connected to the air conditioner motherboard, and their role is to adjust the motor speed by changing the capacitance value.
Therefore, at the time of installation, the leads should be correctly connected according to the capacitor circuit diagram.
It should be noted that the air conditioner power supply should be disconnected before installation to avoid electric shock accidents.
In addition, it is also very important to choose the right type of capacitor.
If the capacitor fails, it should be replaced in time to ensure the normal operation of the air conditioner.
The connection method of fixed frequency air conditioner capacitor is as follows:

1. Open the panel of the air conditioner controller and turn off the power switch. Ensure that the power supply is disconnected.

2. Loosen the screws on the air conditioner shell and remove the shell.

3. Locate the capacitor and its connection position. Usually, the capacitor is connected to the drive motor in parallel, and the connecting line is on the circuit board, and it is marked.

The above is the connection method of fixed frequency air conditioning capacitor. Please note that if you do not understand the basic knowledge of electricity, or do not have maintenance experience, do not operate privately. In the case of repair, it is recommended to seek professional help.
It's a parallel connection.
Because the capacitance in the fixed-frequency air conditioner is used to generate the phase difference, the starting current is provided when the air conditioner compressor is started.
The parallel connection can ensure the normal operation of the air conditioner and improve the service life of the capacitor.
At the same time, it should be noted that the capacitor must be connected in accordance with the circuit diagram of the air conditioner to avoid connection errors.
The capacitor connection mode should be parallel.
Because the fixed-frequency air conditioning circuit needs frequent start-stop operation, and the smooth output of voltage is achieved through capacitance.
The parallel mode can increase the capacity of the capacitor, and the fluctuation of the output voltage of the circuit will be reduced, so as to achieve better results.
At the same time, when selecting the capacitor, it is also necessary to choose the appropriate model and capacity according to the specific situation to ensure the normal operation and long life of the circuit.
Series connection Because the role of the fixed frequency air conditioning capacitor is to store electricity and reverse, the series connection can make the voltage of the capacitor higher to achieve better storage effect.
At the same time, the series connection can also reduce the parasitic inductance of the capacitor and improve the energy efficiency of the air conditioner.
It should be noted that the order of capacitor connection cannot be mistaken, otherwise it will affect the use of capacitors, and even cause damage to the air conditioning system.
The connection method of fixed frequency air conditioning capacitor: first turn off the power, then disassemble the machine shell, find the capacitor, connect the wire according to the mark on the capacitor, generally speaking, the red wire is connected to the positive electrode, and the blue wire is connected to the negative electrode. Note that there may be high voltage on the capacitor, be careful when operating.
After the connection is complete, close the shell and turn on the power to test whether it works normally.
First of all, distinguish the three lines of the fixed-frequency air conditioning compressor, the black is the running end, the white is the control end, and the yellow is the public end
2. First, connect the yellow public end to the starting capacitor
3. Then connect the white control end to the starting capacitor
4, then connect the black running end of the cable clip.
5. Insert the black public end into the power fireline. This completes the connection.
1. First of all, ensure that the power is cut off to ensure safety;

2. Find the capacitor inside the air conditioner, usually located next to the control panel or on the circuit board;
< br >
3. Pay attention to the mark next to the capacitor and find its positive and negative poles;
< br >
4. When connecting the capacitor, connect the wires at both ends of the capacitor to the positive and negative poles of the air conditioner respectively;

5. Tighten capacitors and check whether all connections are firm;
< br >
6. Connect the power supply and start the air conditioner. Check whether any problem exists.

considerations
1. Ensure that all power supplies are disconnected during operation to ensure safety;
2. When replacing the capacitor, the same model and specification as the original capacitor should be used;
3. Use the right tools and techniques to avoid damage to electrical components;
The compressor capacitor is connected to the starting winding capacitor without positive and negative terminals
