Disassembly steps and installation precautions of central air conditioning

Air conditioners have been in our lives for a long time. The central air conditioners installed in some homes or other places may be very old. It is time to disassemble, repair, or replace them. So here comes the problem again, do you know the disassembly and assembly steps of the central air conditioner?

　　Recovered refrigerant

Before disassembling the machine, start the air compressor to set the refrigeration state. After the compressor runs for 5-10 minutes and the refrigeration state is normal, unscrew the cap on the interface between the liquid pipe and the gas pipe of the external machine, and close the high pressure pipe (thin) After 1 minute, the surface of the pipe will condense. Close the low-pressure pipe (thick) shut-off valve immediately, quickly shut down, unplug the power plug, and tighten the safety cap with a wrench. The refrigerant recovery work is now complete.

　　 Disassemble the outdoor unit

　　 After the refrigerant is recovered, the indoor unit can be disassembled. Use a wrench to unscrew the connection lock nut of the indoor unit, and use the prepared sealing sodium screw to protect the wire pattern of the indoor unit connection joint to prevent damage to the joint wire pattern during transportation; then use a cross lifter to remove the control wire. After unscrewing the outer machine connection lock nut, use the prepared sealing sodium to screw the thread of the outer machine connection joint. Then use a wrench to loosen the fixing screws on the feet of the outer machine.

　　Internal machine installation location is determined

　　 When putting down the outdoor unit after disassembly, it is best to hang it with a rope. When discharging, pay attention to balance, avoid vibration and bumps, and pay attention to safety. Slowly straighten the pipe of the outdoor air conditioner and seal the four ports of the connecting pipe with the prepared four plugs to prevent dust and water from entering the air.

　　 Home central air conditioning installation precautions

　　 1. Due to the particularity of household central air-conditioning, its use effect has a great relationship with installation design and installation quality. It cannot be installed by ordinary installation companies, but should be undertaken by professional household central air-conditioning installation companies.

　　2. Before installation, the installer should carefully check the detailed drawings of the household central air-conditioning installation, and coordinate with the design of the performance. However, the current household central air-conditioning installation market is rather chaotic. During the design and installation process, installers do not provide detailed installation drawings, and do not calculate and consider the actual energy efficiency of air-conditioning.

2. The technical quality of the installers is poor. Some construction teams often cannot find a technician with a professional installation certificate. The installation quality problem is serious; the user is not provided with alternative solutions during the installation process, and the performance of the brand machine cannot be determined. Perform reasonable installation, and cannot be fully responsible for the problems that occur during the use of the air conditioner; the contract does not disclose the list of materials required for installation, does not disclose the cost details of the materials, and deceives users by shoddy during the construction process.

　　 After reading the central air-conditioning installation steps introduced by the editor above, I hope to help everyone understand the structure of central air-conditioning. Speaking of disassembly and assembly, the editor of okmarts.com would like to remind everyone that you should not disassemble or disassemble the air conditioner without authorization. This is an errand that can only be done by professionals. Also, you must hire professional personnel to disassemble and assemble, preferably professional The certificate shows that this is the most secure.
