1. Features Nested in the ceiling, space-saving and noble. High capacity of cooling/heating, efficient, and energy-saving. The air outlet is laid out according to you desire. Economic and convenient installation

---Several diffusers branch off from an indoor unit, adjusting the room temperature, which makes many rooms to be air-conditioned with only one indoor unit.

---All models feature thin design making them applicable to ceiling pocket that tends to be shallow Way of air intake and inserting air filter

It is suitable be used for office, hospital, commercial place and home, the air conditioner will create the

comfortable and elegance environment for you.
