Assembling an air conditioner involves several key steps, combining mechanical assembly, system connection, and safety checks. Below is a general guide to the process, often supported by specialized equipment .
1. Prepare Tools and Components
Gather necessary parts: indoor unit (evaporator, fan, control panel), outdoor unit (compressor, condenser, fan), copper pipes, electrical wires, insulation materials, and fasteners.
Use tools like pipe cutters, flaring tools, torque wrenches, and specialized equipment.
2. Assemble the Indoor Unit
Mount the indoor unit on a wall or ceiling using brackets, ensuring stability.
Install internal components: secure the evaporator coil, connect the fan motor to the control board, and attach the air filter and front panel.
3. Assemble the Outdoor Unit
Place the outdoor unit on a level surface (concrete pad or bracket).
Secure core components: mount the compressor, condenser coil, and fan motor in the cabinet. Connect refrigerant lines to the compressor and condenser.
4. Connect Refrigerant Lines
Cut and flare copper pipes to connect the indoor and outdoor units (liquid and suction lines).
Insulate the suction line to prevent condensation.
Use flaring tools to ensure airtight connections, critical for refrigerant efficiency.
5. Electrical Wiring
Connect power cables, control wires, and sensors between the indoor and outdoor units, following the wiring diagram.
Ensure proper grounding to meet safety standards .
6. Leak Detection
Pressurize the refrigerant lines with high-pressure nitrogen to check for leaks.
Apply soapy water to joints; bubbles indicate leaks, which must be repaired before proceeding.
7. Evacuate Air and Moisture
Use a vacuum pump to evacuate air, moisture, and contaminants from the lines. Ensure the system reaches a vacuum level of ≤10Pa.
8. Charge Refrigerant
Charge the system with the specified refrigerant (e.g., R32, R410A) using a refrigerant charging machine (Dongliu offers both standard and explosion-proof models for flammable refrigerants like R32/R290).
Follow precise charging amounts based on the unit’s specifications.
9. Test Operation
Power on the unit and test cooling/heating functions, fan speed, and controls.
Use performance test systems (such as Dongliu’s Air Conditioner Performance Test System) to verify parameters like temperature difference, pressure, and power consumption.
Safety Notes:
For flammable refrigerants (R32, R290), use explosion-proof equipment and ensure ventilation (refer to Dongliu’s Leakage Alarm Detection System for safety monitoring).
Adhere to local electrical and refrigerant handling standards.
Specialized equipment from manufacturers like Foshan Dongliu Automation (e.g., automated assembly lines, leak detectors, and refrigerant charging machines) streamlines this process for mass production, ensuring consistency and compliance with industry standards.
