1. Don't be greedy for the low temperature of the air cooler that does not need to be well-drilled, and the temperature can be set appropriately. Because the cooling fan without drilling wells is cooling, the set temperature is 2 degrees higher, which can save 20% of electricity. In winter, the indoor temperature should be set between 20 degrees Celsius and 24 degrees Celsius;

2. The filter should be cleaned frequently. Too much dust will clog the mesh and make the air conditioner more laborious;

3. The air outlet around the air cooler without drilling wells should be kept smooth. Do not stack large pieces of furniture to block heat dissipation and increase unnecessary power consumption;

4. Avoid direct sunlight. In summer, blocking the direct sunlight on the air cooler can save about 5% of electricity;

5. When the cooling fan without well drilling is used for cooling, the position of the air deflector is adjusted to the horizontal direction, and the cooling effect will be better;

6. The environmental protection air-conditioning piping connecting the indoor unit and the outdoor unit is short and not bent, and the cooling effect is good and does not cost electricity. Even if it is necessary to bend, keep the piping in a horizontal position;

7. Improve the maintenance structure of the room. For some rooms with poor door and window structure and large gaps, it is best to improve them, such as sealing the window gaps with glue paper tape, using sunshade curtains, etc., to reduce the loss of air-conditioning caused by the gaps;

8. Choose environmentally friendly air conditioners with moderate cooling power. An air conditioner with insufficient cooling power not only cannot provide sufficient cooling effect, but also shortens the service life of the air conditioner due to continuous operation for a long time, and increases the possibility of malfunction of the air conditioner. The most important thing is that whether the air cooler without drilling well saves electricity or not depends on its energy efficiency ratio. The higher the energy efficiency ratio, the more energy-saving it is.
