Description:-Converting an inverter split air conditioner (AC) to a non-inverter split AC involves significant modifications, including changing the compressor and the DC inverter PCB (Printed Circuit Board) to components suitable for a non-inverter AC. This process requires advanced technical skills and understanding of HVAC systems. Below is a detailed tutorial on how to perform this conversion:
Tools and Materials Needed:
New non-inverter compressor
New non-inverter PCB board
Refrigerant recovery machine
Manifold gauge set
Vacuum pump
Refrigerant (suitable for the AC unit)
Wrenches and screwdrivers
Electrical tape
Insulation tape
Soldering kit
Multimeter
Safety gear (gloves, goggles, etc.)
Step-by-Step Guide:
1. Safety Precautions:
Power Off: Ensure the AC unit is completely powered off and unplugged from the electrical supply.
Refrigerant Recovery: Use a refrigerant recovery machine to safely recover the refrigerant from the AC system.
2. Remove the Old Compressor:
Access the Compressor: Open the outdoor unit of the split AC to access the compressor.
Disconnect Piping: Carefully disconnect the refrigerant pipes connected to the compressor.
Electrical Connections: Label and disconnect the electrical wires connected to the compressor.
Remove Compressor: Unscrew and remove the compressor from its mountings.
3. Install the New Non-Inverter Compressor:
Position the Compressor: Place the new non-inverter compressor in the mounting position.
Reconnect Piping: Connect the refrigerant pipes to the new compressor, ensuring tight and secure connections.
Electrical Connections: Connect the electrical wires to the compressor as per the wiring diagram of the non-inverter compressor.
Secure Compressor: Screw the compressor into place.
4. Replace the Inverter PCB Board:
Access the PCB: Open the indoor unit to access the inverter PCB board.
Disconnect Wires: Label and disconnect all the wires connected to the inverter PCB.
Remove the Inverter PCB: Unscrew and remove the inverter PCB board.
Install the Non-Inverter PCB: Position the new non-inverter PCB board and screw it into place.
Reconnect Wires: Connect the electrical wires to the new PCB board as per the wiring diagram.
5. System Reassembly:
Check Connections: Ensure all refrigerant and electrical connections are secure and properly insulated.
Close Units: Reassemble the outdoor and indoor units, ensuring all panels and covers are properly secured.
6. Vacuum and Recharge the System:
Vacuum the System: Connect a vacuum pump to the service port and vacuum the system for at least 30 minutes to remove any air and moisture.
Recharge with Refrigerant: After ensuring there are no leaks, recharge the system with the appropriate refrigerant as per the AC unit’s specifications.
7. Testing and Calibration:
Power On: Turn on the power supply to the AC unit.
Operational Test: Test the AC unit to ensure it is functioning correctly. Check for proper cooling performance, compressor operation, and ensure there are no abnormal noises.
Electrical Tests: Use a multimeter to check the electrical parameters and ensure everything is within the specified range.
Final Notes:
Professional Assistance: This process is complex and should ideally be performed by a professional HVAC technician to avoid any potential hazards or damage to the AC unit.
Warranty Void: Modifying an AC unit in this manner will likely void any existing warranty. Consider this carefully before proceeding.
Compliance: Ensure that all modifications comply with local regulations and standards for HVAC systems.
Converting an inverter split AC to a non-inverter split AC is a challenging task that requires a thorough understanding of both types of systems. Proper handling of refrigerants and electrical components is crucial for safety and system performance.
