2. Regularly cleaning the filter screen dust will block the filter screen and reduce the effect of heating and cooling air. It should be cleaned once every half month or so.
3. Opening doors and windows as little as possible can reduce indoor and outdoor heat exchange and help save electricity.
4. Don't block the air outlet of the outdoor unit, otherwise it will reduce the heating and cooling effect and waste electricity.
5. Choose a suitable air outlet angle. Cold air flow is heavier than air and easy to sink, while warm air flow is the opposite. Therefore, the air outlet is upward during refrigeration, and the thermal efficiency is greatly improved.
6. Control startup and use status settings. When starting, set high cold/high heat to achieve the control purpose as soon as possible; When the temperature is suitable, change it to medium-low wind to reduce energy consumption and noise.
7. The connecting pipe should not be too long. The outdoor unit should be placed in a dry and easy-to-dissipate place, and the connecting pipes of indoor and outdoor units should not exceed the recommended length as far as possible, so as to enhance the refrigeration effect.
Simple fault checking method
1. The air conditioner is broken. Is there a power outage? Is the power fuse open? Is the power on/off in the "off" position? Has the power plug been unplugged?
2. The operation is noisy. Is the installation tilted? Is the grille closed?
3. The room is not cold. Are the doors and windows open? Is there any dust jam on the dust filter net? Are the air inlets and air outlets of indoor or outdoor units blocked? Is the set temperature too high? Is the peak voltage too low or fluctuating too much?
4. The refrigeration is not good. Is the outdoor unit exposed to the sun or the outdoor temperature exceeds 45℃?
