70-95kW Capacity Precision Air Conditioning System with R22(R407C/R410A)

Products Introduction                                    

With the development of the Internet and information technology, the amount of data processing and storage has continued to grow, and this growth has also led to a continuous increase in the heat density of the data center, and has brought about dynamically changing load requirements at different time periods. Coolnet precision air conditioners can be combined with microprocessor systems to provide full control of computer rooms and precision equipment workshops, including control of ambient temperature, humidity and air cleanliness in these locations. The precision air conditioner can control the temperature and relative humidity of the equipment room within plus or minus 1 degree Celsius and 5%, thus greatly improving the life and reliability of the equipment.

Applications                                  

• Large, medium and small exchange room, Large data center
• Small and medium computer rooms, equipment rooms, power rooms
• Outdoor electronics, Communication equipment rooms
• Substations, Laboratories, Testing rooms, Storage rooms

The unit uses a high-efficiency fan and a fully enclosed compressor system to reduce operating costs and always pay attention to energy efficiency.

Multiple air supply
The air supply method of the air-conditioned room depends on the source and distribution characteristics of the heat in the room. According to the dense arrangement of equipment in the computer room, the number of cables and bridges, and the wiring method, the air supply method of the air conditioner is divided into lower delivery, upper return, top feed back, top feed side back, side feed side back.

Static pressure box air supply
The air conditioner in the computer room usually does not use pipes, but uses the space at the lower part of the raised floor or the upper part of the ceiling as the return air of the static pressure box. static pressure is equal.
