T3 Condition Computer Room Precision Air Conditioner of the data center room is mainly divided into air cooling direct evaporation air conditioning system, water cooling direct evaporation air conditioning system, chilled water air conditioning system, and dual cooling source air conditioning system.

The chilled water system with the T3 Condition Computer Room Precision Air Conditioner in the data center room as the centralized cold source, compared with the independent direct evaporation air conditioning system, the refrigeration efficiency is higher, the equipment is more centralized, the operation is more stable, the failure rate and maintenance cost is lower, many large data centers abroad widely used chilled water air conditioning system. Alxi proposed the data center natural cooling chilled water system, has been approved by the national patent. It through the careful design and control logic of the frozen water circulation pipeline optimization, implementation and internal air conditioning room air distribution perfect match, and can according to indoor heat load and the change of the outdoor environment, flexible adjustment of frozen water, put the benefits of natural cooling, always keep the unit run efficiently. According to the different climate conditions of the installation area, the air conditioning solution of the data center room can achieve 20% ~ 50% energy saving, which greatly reduces the operation cost. The initial investment in air conditioning equipment can be recovered in up to two years, and the service life of the whole unit is at least 10 years.

Chilled water air conditioning system includes chilled water type unit and cold water host without cold source.
