Seven attentions for air conditioners:
1. The observation aircraft has barrier-free access, removes the interior hood and clears the outer aircraft's vicinity。
2. To open the inner shell to observe whether there is dust and odor in the internal filter, please clean the filter regularly。
Method of cleaning the filter:
1. First, power cuts;
2. Open panels (a cabinet-type machine with a fixed screw with a wind fence should first remove the screws and open the wind fence);
3. Remove filters;
4. Cleaning of filters (cleaning of dust with a hairbrush cleaner, cleaning with water, oil when it is too dirty, washing with detergent or neutral soap, drying with water filtering);
5. Be careful not to wash with hot water above 40°c。
Three, three-to-five minutes of plug-in, setting the remote control in a cooling mode, setting the temperature at minimum and operating (preferably at noon and afternoon test)。
4. The air conditioner, after operation, sets the wind speed switch for the remote control at different slots to observe the presence of abnormal noise。
Five, 15 minutes. Observe whether the exterior fan is functioning properly and there is an abnormal noise on the exterior。
6 on-board for about 30 minutes to observe whether there is a chilling feeling of internal winding, whether out-of-house water flows out of the out-pipe and whether the flow is smooth。
7. Normal phenomena in air conditioning operations:
Accelerator or plastic sound is occasional: this is due to cold and heat expansion of the interior panel during air conditioning cooling。
2. Acoustic or streaming sound: a voice generated by the movement and evaporation of refrigerants within aircraft。
3. White smoke is blowing out of the inside: indoor air is wet enough to be produced by air-conditioning cooling。
4. Water beads on a leaf or pipe road: the interior is very wet, it is set to cause secondary condensation due to low temperatures, it is set to the extent possible to keep the interior vents at a level and the interior air is ventilated。
5. Naked out-of-the-frame pipes, and drops of water on the interfaces: the formation of condensed water molecules in the air is normal。
6. The voice of the fac exterior is small at large: this is due to changes in the frequency of fac compressors operating。
