Central air conditioning installation process:
1, internal crane
Infrared positioning: Determine the installation position according to the previously determined design drawings. In order to avoid dislocation, a professional infrared locator is used to determine the position.
Ensure the level: after fixing, be sure to use a professional level meter to ensure the level inside the machine, to ensure smooth drainage and no water accumulation in the water tray.
Protect the internal machine: Finally, remember to wrap the internal machine with plastic film and other materials to prevent dust from entering and affecting the normal work of the machine.
Workshop equipped with copper pipes:
Tube expanding: When the copper tube with the same diameter is to be welded, it must be expanded first, otherwise it will be easy to weld badly.
Welding: nitrogen must be replaced during welding, and the copper tube should be cooled naturally before the next process, otherwise it will easily leak.
Wrapping: When wrapping the copper tube with thermal insulation material, it should be wrapped from bottom to top, and there should be no seams, otherwise it will be easy to flow back in rainy days.
Spacing: In order to avoid shaking and loosening and ensure the firmness of the supporting part, the spacing between two copper tube brackets should not exceed1.5m..
Laying condensate pipe
Slope: The paved condensate pipe should have a slope of at least1100, which will not affect the decoration effect, but also ensure its normal drainage.
2. Install the outdoor unit
External wall hole: the angle should be inclined downward to prevent rainwater from flowing backwards in rainy days. And try to ensure that its surface energy is smooth and flat, and put on a pipe sleeve, otherwise it is easy to tear the insulation material on the outer wall of the pipeline.
Shockproof rubber: When installing the outdoor unit, the bottom should be covered with shockproof rubber to prevent the outdoor unit from being affected by vibration.
3. Testing and debugging
Leakage inspection: After the internal and external machines are connected, leakage inspection shall be conducted to confirm that there is no leakage in the internal and external machines and pipeline system.
Vacuum: Remember the vacuum to ensure that the system is dry. If there is moisture in the system, it is easy to cause system ice blocking and electrical insulation damage.
Trial operation: Finally, a trial operation is needed to confirm whether the data such as return air temperature, supply air temperature, operating current and voltage of the air conditioner are normal.
