2. Full water system: Each air-conditioned room is equipped with air treatment equipment, and the low-temperature chilled water (or heating hot water) made by the central refrigeration unit needs to be sent to each room. It is generally used in places with many rooms and different use times, such as hotel rooms, KTV, small conference rooms, hotel rooms and so on. Obviously, there are a lot of air handling equipment, which increases the difficulty of maintenance and management. In addition, the running of water pipes indoors also increases the hidden dangers of water leakage and condensate. Total water and total air are equivalent to two opposite ways, one is broken into parts and the other is broken into parts.

Disadvantages are that outdoor units affect the appearance, low efficiency and indoor ceiling modeling.
