How to choose air-conditioners?
1. Make sure the voltage is single phrase or 3 phrases, as well as the highest voltage. Also whether the air-conditioner can be installed on external wall.
2. The air-conditioner is for household, commercial, industrial or other special usage.
3. Choose the right cooling capacity to suit the size of the room. Whether the room has direct sunlight, the ventilation condition, etc are also considerable factors.
4. For restaurants, halls, conference rooms, audio-visual rooms & jewelry shops, which occupied large space needs larger cooling capacity than general air-conditioner.
