Recovering the refrigerant
Whether in the winter or summer, we should collect the refrigerant when moving the machine. Disassemble should start before air conditioning units, available remote control to set the refrigeration state of air conditioning units, to be the normal state of operation of the compressor refrigeration with a wrench, unscrew the insurance cap on the liquid pipe and gas pipe outside the machine interface, and shut down the high-pressure pipe (fine) tube appearance condensation cutoff valve l min (air conditioning is about two minutes, etc.), immediately turn off the low-pressure pipe (coarse) cut-off valve, with the rapid shutdown, unplug the power plug, use a wrench to tighten the insurance cap, bringing recovery of refrigerant is completed. (If it is winter, are advised to use warm towel to cover the indoor temperature sensor probe, and then control the cold state to set the boot.)
Demolish the indoor unit
The indoor unit connected locknuts with a wrench unscrew ready sealed sodium sub-spin good cover the indoor unit connector lines, prevent joint line break something in conveying; then screwdriver to remove the control line. It should also be marked to avoid a wrong installation. If you pick the wrong signal line or power cord, which may cause the stop of the machine outside, or the machine is uncontrolled. Within the machine hung board generally fixed more firmly, more difficult to unload; Remove the peg board, and place it in the plane of the concrete floor and then pat flat and make some correction.
Demolish the outdoor unit
The demolition of the outdoor unit should be carried out by professional refrigeration repairman in the circumstances to ensure the safety of demolition. Tighten away the lock letters, applications live in the prepared sealed sodium sub spin good care out machine connector wire pattern. Use a wrench to loosen the screws outside the foot of machine. Put down the outdoor unit after the demolition of the best with a rope, we should pay attention to the balance at the same time of unloading, to avoid vibration, bump, and pay attention to the downstairs cars and people.
The installation of air conditioning
We should pay attention to reinstall install location and convection when reinstalling the ceiling air conditioner. Finally, carry out the leak detection and observe whether there are bubbles in each connector by detergent, and we can tighten the valve after verifying that there is no leakage. Installed within the machine, rough brass connected to slightly open the valve, close the valve when the gas and other thin tube feeling cold, thin tube connected. (in order to exclude the air pipe). Open the valve. Coat it with soap and water (or detergent plus water) in the joints to see if there is no leak. The brass should not be exposed.
www.airconditionings.cn established a national postdoctoral scientific research workstation and two provincial technical centers. Shenling has also constructed four state-level product performance- testing centers for packaged air conditioners, high-temperature-use air conditioners, air and water- cooled chillers and FCU & AHU. Moreover, a joint laboratory named Shenling-Siemens network-based professional lab for air-conditioning operating & monitoring system was set up in Shenling, which was the first lab of this kind co-constructed with Siemens in HVAC industry in china.
