The air -conditioning unit is an important part of the central air -conditioning system, and its installation quality and standardization directly affect the performance and safety of the entire system.The following are several key issues that need to be paid attention to when installing the air -conditioning unit:
1. As far as possible, the air conditioner and indoor machine are placed to reduce the number of elbows of the refrigerant pipeline.
2. Add rubber pads between the racks and branches to reduce the vibration of the air conditioner outdoor and indoor machine.
3. When connecting the gas tube and the fluid pipe, you must keep the warmth. Do not weld the two together.In order to facilitate and support, they can be tied together, but they must be separated with insulation materials.At the wall, the refrigerant pipes are treated with the heating layer and sealing materials of the refrigerant pipeline to reduce the vibration and maintain a certain flexibility.
4. Turn off the outdoor and indoor intercept valve, and the leakage treatment is performed after the welding of the pipeline is welded.After the vacuum and drying are correct, if the refrigerant is required, the liquid refrigerant is charged next to the liquid intercept valve.
5. The drainage pipe should be extended out of the building, and its drainage shall not flow to the wall.
6. When the initial boot or long -term shutdown is reorganized, the power must be connected in advance to heat the crankshaft box for at least 6 hours (unless the surface temperature of the compressor is at least 10 ° C than the surrounding temperature).
7. Keep the surface of the condenser and evaporator clean and clean it regularly.
