Precautions:
1. For central air conditioners that have been sitting idle for a long time, there is already a lot of dust attached to the filters and the evaporator fins, so it needs to be cleaned before re-use to avoid the spread of mold from the air vents.
2. The core of the central air conditioner is the compressor, which contains lubricating oil (frozen oil). If not used for a long time, the frozen oil will be mixed with the liquid refrigerant. Before using again, please provide power one day in advance to warm up the central air conditioning compressor, so that the liquid refrigerant in the compressor is vaporized and separated from the frozen oil, so as not to cause damage to the compressor due to liquid shock when the compressor starts.
3, when using air conditioning, try to open doors and windows, and use thick, sun-protective curtains. Because in the cooling or heating system, the space is relatively closed, open doors and windows, will lead to air flow, indoor temperature fluctuations.
